A bharrachd air, bu chòir puing leaghaidh agus teòthachd giollachd an neach-giùlain a bhith co-chòrdail ri no beagan nas ìsle na an stuth amh plastaig targaid, gus lobhadh an neach-giùlain no am plastag targaid a sheachnadh rè giollachd.
1.2.3 Cur-ris: An Co-phàirt Gnìomhach Cuideachail
Tha cur-ris nam pàirtean taice air an cur ris gus coileanadh giollachd a leasachadh, dispersibility agus cleachdadh coileanadh masterbatch, cunntasachd airson 1%-10% den sgrìobhadh masterbatch. Tha an seòrsa agus an dòs de chur-ris air a dhearbhadh a rèir an seòrsa masterbatch agus riatanasan giullachd. Tha cur-ris cumanta a’ toirt a-steach:
- Luchd-sgaoilidh: An rud as cudromaiche ann an masterbatch, a dh’ fhaodadh teannachadh uachdar pigmentan a lughdachadh, casg a chur air cruinneachadh pigment, agus dèan pigmentan air an sgapadh gu cothromach anns a’ ghiùlan. Am measg an luchd-sgaoilidh cumanta tha cèir polyethylene, cèir polypropylene, searbhag stearic, stearate calcium, etc. Faodaidh cur-ris luchd-sgaoilidh leasachadh mòr a thoirt air sgapadh masterbatch, dèanamh cinnteach à dath èideadh de thoraidhean, agus lughdaich caitheamh uidheamachd eas-tharraing.
- Co-fhreagarrachd: Air a chleachdadh gus an co-chòrdalachd eadar pigmentan agus luchd-giùlan a leasachadh, agus eadar masterbatch agus targaid stuthan amh plastaig. Mar eisimpleir, nuair a tha droch cho-chòrdalachd aig an neach-giùlain agus am plastaig targaid (leithid giùlan PE agus plastaig PA), luchd-coimhid (leithid polyethylene grafted anhydride maleic) faodar a chur ris gus neart ceangail a neartachadh eatorra, seachain sgaradh masterbatch agus targaid plastaig rè giollachd, agus a’ leasachadh feartan meacanaigeach thoraidhean.
- Stabilizers teas: Air a chleachdadh gus casg a chuir air lobhadh pigmentan, luchd-giùlan agus plastaic targaid aig àm giollachd eas-tharraing àrd-teòthachd. Tha stabilizers teas cumanta a’ toirt a-steach salainn luaidhe, stabilizers calcium-sinc, stabilizers staoin organach, etc., a tha air an taghadh a rèir teòthachd giollachd agus riatanasan dìon na h-àrainneachd.

- Bealaidh: Air a chleachdadh gus an suathadh eadar stuthan agus uidheamachd eas-tharraing a lughdachadh (sgread, baraille, ceann bàs), leasachadh fluidity giollachd, lùghdachadh caitheamh lùtha, agus seachain stuth a’ cumail ri uidheamachd, a tha cuideachail airson adhartas rèidh ann an giullachd eas-tharraing.
1.2.4 Prionnsabal obrach masterbatch
Tha prionnsapal obrach masterbatch stèidhichte air an sgaoileadh èideadh de pigmentan dùmhlachd àrd anns a’ ghiùlan. Aig àm giollachd stuthan plastaig, àireamh bheag de masterbatch (mar as trice 1%-5%) air a mheasgachadh le stuthan amh plastaig gun dath. Fo ghnìomhachd teòthachd àrd agus feachd rùsgaidh aig àm eas-tharraing no cumadh stealladh, bidh giùlan an masterbatch a 'leaghadh agus a' measgachadh leis na stuthan amh plastaig targaid, agus tha na pigmentan a tha sgapte gu cothromach air an leigeil ma sgaoil agus air an sgaoileadh gu co-ionnan anns a’ mhaitrix plastaig targaid, mar sin a’ coileanadh adhbhar dathadh stuthan plastaig. Is e prìomh adhbhar a’ phròiseis seo gum feum na pigmentan anns an masterbatch a bhith air an sgapadh gu co-ionnan gun a bhith a’ cruinneachadh, air neo bidh e ag adhbhrachadh spotan dath, eadar-dhealachadh dath agus uireasbhaidhean eile anns na toraidhean dathte.
1.3 Seòrsachadh cumanta de Masterbatch
Faodar Masterbatch a roinn ann an diofar sheòrsaichean a rèir diofar inbhean seòrsachaidh, leithid seòrsa dath, seòrsa neach-giùlain, raon tagraidh, seòrsa gnìomh, etc. Tha an seòrsachadh ceart a’ cuideachadh le tuigse nas fheàrr fhaighinn air feartan coileanaidh agus riatanasan giullachd masterbatch, agus tagh uidheamachd eas-tharraing iomchaidh agus dòighean giullachd.
1.3.1 Seòrsachadh a rèir seòrsa dath
A rèir an t-seòrsa de cho-phàirt dathte, faodar masterbatch a roinn ann an dath masterbatch, masterbatch geal agus masterbatch dubh.
- Masterbatch dath: An seòrsa masterbatch as cumanta, a bhios a’ cleachdadh pigmentan organach no neo-organach de dhiofar dhathan (leithid dearg, buidhe, gorm, uaine, orains) mar phàirtean dathte, agus tha e air a chleachdadh airson dathadh stuthan plastaig de dhiofar dhathan. An neart clò-bhualaidh, Is e soilleireachd dath agus dispersibility dath masterbatch na prìomh chomharran airson a chàileachd a thomhas.
- Masterbatch geal: A 'cleachdadh titanium dà-ogsaid (TiO2) mar am prìomh phàirt dathte, it is used for whitening plastic products or as a base color for light-colored masterbatch. The whiteness, covering power and dispersibility of white masterbatch are the key indicators. Titanium dioxide has high hardness, which has high requirements on the wear resistance of extrusion equipment.
- Black Masterbatch: Using carbon black as the main coloring component, it is used for black coloring of plastic products. Carbon black has good UV resistance and weather resistance, and can also improve the mechanical properties of plastic products. The dispersibility of carbon black is the key to the quality of black masterbatch. Poor dispersibility will cause black spots and streaks in products.
1.3.2 Classification by Carrier Type
According to the type of carrier, masterbatch can be divided into PE masterbatch, PP masterbatch, PVC masterbatch, PA masterbatch, PET masterbatch, etc.
- PE Masterbatch: Using PE as the carrier, it is suitable for coloring PE plastic products (such as PE films, PE pipes, PE injection molding parts). It has good compatibility with PE raw materials, good processing fluidity and uniform coloring.
- PP Masterbatch: Using PP as the carrier, it is suitable for coloring PP plastic products (such as PP fibers, PP injection molding parts, Duilleagan PP). It has good heat resistance and is suitable for high-temperature processing of PP.
- PVC Masterbatch: Using PVC as the carrier, it is suitable for coloring PVC plastic products (leithid pìoban PVC, Pròifilean PVC, PVC films). It needs to be matched with PVC heat stabilizers to avoid PVC decomposition during processing.
- Engineering Plastic Masterbatch: Using engineering plastics (PA, PC, PBT, etc.) as carriers, tha e freagarrach airson dathadh bathar plastaig innleadaireachd (leithid pàirtean càr, co-phàirtean dealain). Tha deagh sheasamh teas aige agus co-chòrdalachd le plastaic innleadaireachd, agus tha riatanasan àrd aige air uidheamachd giollachd eas-tharraing.
1.3.3 Seòrsachadh a rèir raon tagraidh
A rèir raon tagraidh masterbatch, faodar a roinn ann an fiber masterbatch, masterbatch film, masterbatch cumadh buille, masterbatch eas-tharraing, masterbatch cumadh stealladh, etc., a tha a rèir nan còig prìomh raointean tagraidh de masterbatch.
- Fiber Masterbatch: Air a chleachdadh airson dathadh snàithleach ceimigeach (leithid snàithleach polyester, freumhag nylon), a tha air a chleachdadh ann am bratan-ùrlair, aodaich, cuiseanan agus bathar eile. Feumaidh e dispersibility àrd agus luaths dath, agus chan eil dath sam bith a’ seargadh aig àm snìomh agus fighe.
- Film masterbatch: Air a chleachdadh airson dathadh filmichean plastaig (leithid pocannan ceannach, filmichean tilgeadh, filmichean ioma-fhillte), a dh’ fheumas soilleireachd àrd agus dath èideadh, agus gun spotan dath no sreathan air uachdar an fhilm.
- Masterbatch Moulding Sèididh: Air a chleachdadh airson dath a dhèanamh air toraidhean cumadh buille (leithid soithichean meidigeach agus cosmaigeach, soithichean ola lubaidh agus peant), a dh’ fheumas fileantachd giollachd math agus dathadh èideadh, agus gun deformachadh no eadar-dhealachadh dath air a’ ghobhar.
- Masterbatch eas-tharraing: Air a chleachdadh airson dath a dhèanamh air toraidhean eas-tharraing (leithid duilleagan, pìoban, uèirichean agus càbaill), a dh ’fheumas seasmhachd meud math agus dath èideadh, agus gun eadar-dhealachadh dath air uachdar an toraidh.
- Masterbatch molltair stealladh: Air a chleachdadh airson dath a dhèanamh air toraidhean cumadh stealladh (leithid pàirtean càr, bathar eileagtronaigeach, stuthan togail, innealan taighe, àirneis, dèideagan), a dh’ fheumas dispersibility àrd agus coileanadh seasmhach, agus chan eil eadar-dhealachadh dath ann eadar batches de thoraidhean.
1.3.4 Seòrsachadh a rèir seòrsa gnìomh
A rèir gnìomhan a bharrachd masterbatch, it can be divided into ordinary masterbatch (only coloring function) agus masterbatch gnìomh (dathadh + gnìomhan a bharrachd). Is e masterbatch gnìomh an gluasad leasachaidh sa ghnìomhachas, agus tha seòrsachan cumanta a’ toirt a-steach masterbatch lasair-retardant, masterbatch antistatic, masterbatch antibacterial, Masterbatch a tha an aghaidh UV, masterbatch cruaidh, etc. Feumaidh masterbatch gnìomh cuir-ris gnìomh co-fhreagarrach a bharrachd air bunait masterbatch àbhaisteach, aig a bheil riatanasan nas àirde a thaobh buaidh measgachadh agus sgapadh uidheamachd eas-tharraing.
2. Teicneòlas giollachd bunaiteach de Masterbatch: Teicneòlas eas-tharraing Twin-Screw
Tha giollachd Masterbatch sa mhòr-chuid a’ toirt a-steach measgachadh, eas-tharraing, fuarachadh, granulation agus pròiseasan eile, am measg sin tha teicneòlas eas-tharraing dà-sgriubha mar phrìomh theicneòlas measgachadh masterbatch agus granulation. An coimeas ri teicneòlas eas-tharraing aon-sgriubha, Tha buannachdan aig teicneòlas eas-tharraing dà-sgriubha airson comas measgachadh làidir agus sgaoilidh, smachd teòthachd mionaideach, ùine còmhnaidh goirid, èifeachdas toraidh àrd agus sùbailteachd làidir gu stuthan amh, a dh'fhaodas fuasgladh èifeachdach a dhèanamh air na prìomh dhuilgheadasan a thaobh giollachd masterbatch (leithid cruinneachadh pigment, measgachadh neo-chothromach, èifeachdas toraidh ìosal) agus dèanamh cinnteach à càileachd bathar masterbatch.
Is e measgachadh masterbatch aon de na prìomh thagraidhean aig extruders dà-sgriubha. Tha càileachd masterbatch air a dhearbhadh gu dìreach le coileanadh an extruder dà-sgriubha agus reusantachd a ’phròiseas giullachd. Is e na prìomh riatanasan airson giollachd masterbatch airson extruders dà-sgriubha: measgachadh làidir agus buaidh sgaoilidh (gus dèanamh cinnteach à sgapadh aon-dath de pigmentan), smachd teòthachd mionaideach (gus lobhadh pigment agus truailleadh luchd-giùlain a sheachnadh), feachd gearraidh iomchaidh (gus cruinneachaidhean pigment a bhriseadh gun a bhith a’ dèanamh cron air mìrean pigment), èifeachdas toraidh àrd (gus coinneachadh ri feumalachdan cinneasachaidh mòr) agus deagh sheasamh an aghaidh caitheamh (gus gabhail ri caitheamh pigmentan àrd-chruaidh leithid titanium dioxide agus carbon dubh).
2.1 Duilgheadasan giullachd Masterbatch agus riatanasan airson uidheamachd eas-tharraing
Ged a tha teicneòlas eas-tharraing dà-sgriubha freagarrach airson giollachd masterbatch, air sgàth cho sònraichte ‘s a tha sgrìobhadh masterbatch (susbaint àrd pigment, cruinneachadh furasta de pigmentan) agus riatanasan giullachd (sgaoileadh èideadh, coileanadh seasmhach), tha mòran dhuilgheadasan ann fhathast ann an giullachd fìor. Tha na prìomh dhuilgheadasan giullachd agus riatanasan co-fhreagarrach airson uidheamachd eas-tharraing mar a leanas:
2.1.1 Agglomeration Pigment agus Droch Sgapadh
Dathan (gu sònraichte pigmentan neo-organach leithid titanium dioxide agus carbon dubh) tha polarity làidir agus farsaingeachd uachdar sònraichte mòr aca, a tha furasta an cruinneachadh ann am mìrean mòra rè stòradh agus measgachadh. Mura h-urrainnear na agglomerates a bhriseadh gu h-iomlan agus an sgapadh rè giollachd eas-tharraing, bidh droch sgapadh aig a’ masterbatch, agus bidh spotan dath air na toraidhean plastaig dathte, sreathan dath agus dath neo-chothromach, a bheir buaidh mhòr air càileachd toraidh. Is e seo an duilgheadas as cumanta agus as cudromaiche ann an giullachd masterbatch.
Feumaidh seo gum bi comas làidir measgachadh is sgaoilidh aig an uidheamachd eas-tharraing agus feachd rùsgaidh iomchaidh. Bu chòir don extruder dà-sgriubha gabhail ri structar co-chuairteachaidh eadar-mheadhanach, agus bu chòir gum biodh an sgriubha air a uidheamachadh le eileamaidean measgachadh gu leòr agus eileamaidean rùsgaidh gus feachd rùsgaidh làidir agus feachd glùineachaidh a ghineadh rè cuairteachadh, a dh’ fhaodas na cruinneachaidhean pigment a bhriseadh gu tur agus na pigmentan a sgaoileadh gu cothromach anns a’ ghiùlan. A bharrachd air, the screw speed and extrusion pressure should be adjustable to adapt to different types of pigments and masterbatch concentrations.
2.1.2 Pigment Decomposition and Carrier Degradation Caused by Overheating
Most pigments (especially organic pigments) have poor heat resistance, and the carrier (leithid PE, PP) also has a certain temperature resistance limit. If the extrusion temperature is too high or the residence time of the material in the extruder is too long, the pigment will decompose (resulting in color fading, discoloration), and the carrier will degrade (resulting in reduced mechanical properties of the masterbatch). This is another key difficulty in masterbatch processing.
This requires the extrusion equipment to have precise temperature control capacity and short residence time. The barrel of the extruder should be divided into multiple temperature control sections, and the temperature of each section should be precisely controlled within the optimal range (usually 150-220℃ for ordinary masterbatch, 200-280℃ for engineering plastic masterbatch), with a temperature control precision of ±1℃. The screw structure should be optimized to shorten the residence time of the material in the extruder (mar as trice 1-3 mionaidean), avoiding long-term contact between the material and high temperature.
2.1.3 Wear of Screw and Barrel Caused by High-Hardness Pigments
Inorganic pigments such as titanium dioxide and carbon black have high hardness (Mohs hardness 5-7), which will cause serious wear to the screw and barrel of the extruder during extrusion processing. Ma tha droch sheasamh aig an sgriubha agus am baraille, bidh iad air an caitheamh gu sgiobalta, resulting in reduced shear force and mixing capacity of the extruder, affecting the dispersibility of the masterbatch and reducing the service life of the equipment.
This requires the screw and barrel of the extruder to be made of high-quality wear-resistant materials and processed by advanced manufacturing technology. Mar eisimpleir, the screw and barrel can be made of imported wear-resistant alloy steel, and undergo bimetallic composite treatment or laser cladding treatment, which can greatly improve the wear resistance and corrosion resistance of the screw and barrel, and adapt to the processing of masterbatch with high-hardness pigments.
2.1.4 Instability of Product Quality Between Batches
Masterbatch processing requires strict control of various parameters (such as formula ratio, measgachadh ùine, extrusion temperature, astar sgriubha, astar beathachaidh). If the parameters fluctuate, the quality of the masterbatch (such as concentration, sgapadh, tinting strength) will be unstable, resulting in color difference between batches of colored products, which will affect the reputation of the manufacturer.
This requires the extrusion equipment to have intelligent control capacity and stable performance. The extruder should be equipped with a PLC intelligent control system, which can realize precise control of feeding speed, astar sgriubha, extrusion temperature and other parameters, and store multiple sets of formula parameters. When producing different batches of masterbatch, chan fheumar ach na paramadairean co-fhreagarrach a ghairm, a’ seachnadh ath-dhebugging, ensuring the stability of product quality between batches.
2.1.5 High Requirements on Processing Fluidity
Masterbatch has high pigment content, which will reduce the processing fluidity of the material. If the processing fluidity is too poor, bidh an stuth duilich a ghiùlan agus a thoirt a-mach, mar thoradh air èifeachdas toraidh ìosal, cuideam eas-tharraing neo-sheasmhach agus eadhon bacadh uidheamachd.
Feumaidh seo gum bi comas giùlain làidir agus feachd rùsgaidh a ghabhas atharrachadh aig an uidheamachd eas-tharraing. Bu chòir don extruder dà-sgriubha gabhail ri raon sgriubha reusanta, dealbhadh co-mheas luaidhe agus teannachaidh, agus bu chòir an sgriubha a bhith uidheamaichte le eileamaidean giùlain gu leòr gus dèanamh cinnteach gun tèid stuthan a ghiùlan gu rèidh. A bharrachd air, faodar an teòthachd eas-tharraing atharrachadh gu h-iomchaidh gus fluidity giollachd an stuth a leasachadh, agus faodar bealaidh a chuir ris gus an suathadh eadar stuthan a lughdachadh.
2.2 Prionnsabal Obrach agus Sruth Pròiseas de Extrusion Twin-Screw Masterbatch
Tha am pròiseas eas-tharraing dà-sgriubha de masterbatch na phròiseas measgachadh corporra iom-fhillte, a tha sa mhòr-chuid a’ toirt a-steach pretreatment stuthan amh, premixing, a 'biathadh, leaghadh, measgachadh agus rùsgadh, eas-tharraing, fuarachadh, gràinealachd, sgrìonadh agus pacadh. Is e am prìomh adhbhar pigmentan a sgaoileadh gu cothromach, luchd-giùlan agus stuthan cur-ris gus gràinneagan masterbatch àrd-inbhe a chruthachadh. Tha am prionnsapal obrach sònraichte agus sruth pròiseas mar a leanas:
2.2.1 Pretreatment Stuth Raw
Is e pretreatment stuthan amh bunait giollachd eas-tharraing masterbatch, a bheir buaidh dhìreach air buaidh measgachadh agus càileachd toraidh. Tha stuthan amh masterbatch sa mhòr-chuid a’ toirt a-steach pigmentan / dathan, luchd-giùlain, stuthan cur-ris (luchd-sgaoilidh, luchd-coimhid, stabilizers teas, etc.). Tha na ceumannan pretreatment mar a leanas:
- Làimhseachadh a 'tiormachadh: Cuid de pigmentan (leithid pigmentan organach) agus luchd-siubhail (leithid PA, Peata) tha sùghadh uisge àrd aca. Ma tha an taiseachd ro àrd, bheir e builgeanan, cruinneachadh agus uireasbhaidhean eile anns an masterbatch aig àm giollachd eas-tharraing, agus eadhon ag adhbhrachadh truailleadh hydrolytic den neach-giùlain. Uime sin, feumaidh na stuthan amh a bhith air an tiormachadh mus tèid an giullachd. Tha an teòthachd agus an ùine tiormachaidh air an co-dhùnadh a rèir an seòrsa stuth amh: Mar eisimpleir, tha pigmentan organach air an tiormachadh aig 60-80 ℃ airson 2-4 uairean, Tha luchd-giùlan PE / PP air an tiormachadh aig 80-100 ℃ airson 3-5 uairean, agus PA luchd-còmhdhail air an tiormachadh aig 100-120 ℃ airson 6-8 uairean. Bu chòir smachd a chumail air susbaint taiseachd nan stuthan amh tiormaichte gu h-ìosal 0.1%.
- A 'bruthadh agus a' sgoltadh: For pigments with large particle size (such as titanium dioxide agglomerates) and carriers with uneven particle size, crushing and sieving treatment should be carried out to ensure the uniformity of raw materials. Bu chòir smachd a chumail air meud nan stuthan amh a tha air am pronnadh aig 20-40 mogal, which is conducive to the uniform mixing of raw materials and the breaking of pigment agglomerates during extrusion.
- Impurity Removal: The raw materials may contain impurities (such as metal particles, clachan, duslach) during production and transportation. Impurities not only affect the quality of the masterbatch, ach cuideachd caith sgriubha agus baraille an extruder, agus eadhon bacadh uidheamachd adhbhrachadh. Uime sin, the raw materials must be filtered and removed before use, using a filter screen with appropriate mesh size to remove impurities.
2.2.2 Premixing
Premixing is the key step to improve the mixing and dispersing effect of masterbatch. A rèir a 'cho-mheas foirmle, the dried, crushed and impurity-removed pigments, bidh luchd-giùlan agus stuthan cur-ris air an cur ann am measgadair aig astar luath airson premixing. Is e adhbhar premixing toirt air na pigmentan agus na stuthan cur-ris cumail gu co-ionnan ri uachdar nam mìrean giùlain, cruthaich measgachadh tòiseachaidh, agus cuir bunait airson an sgapadh èideadh rè eas-tharraing.
Is e prìomh pharaimearan premixing astar measgachadh, measgachadh ùine agus teòthachd measgachadh. Tha an astar measgachadh san fharsaingeachd 800-1200 rpm, tha an ùine measgachadh 5-10 mionaidean, agus tha an teòthachd measgachadh air a smachdachadh aig 40-60 ℃. Faodaidh an teòthachd measgachadh iomchaidh feabhas a thoirt air gèilleadh cur-ris (leithid luchd-sgaoilidh) don neach-giùlain agus pigmentan, brosnachadh measgachadh èideadh. Airson masterbatch le susbaint àrd de pigment (Leithid 50% gu h-àrd), faodar an ùine premixing a leudachadh gu h-iomchaidh, agus faodar beagan inneal-sgaoilidh a chuir ris an toiseach gus sgapadh pigmentan a leasachadh. An dèidh premixing, bu chòir don mheasgachadh a bhith èideadh ann an dath, às aonais cruinneachaidhean pigment follaiseach agus mìrean cur-ris.
2.2.3 A 'biadhadh agus a' giùlan
The premixed mixture is sent to the feeding hopper of the twin-screw extruder through a screw feeder or a belt feeder. The feeding device of the extruder is usually equipped with a frequency conversion speed regulation function, which can adjust the feeding speed according to the screw speed and extrusion speed to ensure that the materials enter the extrusion cavity stably and uniformly, avoiding material accumulation or insufficient feeding.
The feeding hopper is also equipped with a drying device (such as an electric heating jacket) to prevent the raw materials from absorbing moisture again during feeding. For masterbatch with high pigment content and poor fluidity, a forced feeding device can be selected to ensure the smooth feeding of materials. A bharrachd air, the feeding port of the extruder should be smooth, without dead corners, to avoid material sticking and accumulation.
2.2.4 A' leaghadh, A 'measgachadh agus a' rùsgadh
Tha na stuthan a tha a’ dol a-steach do chuas eas-tharraing an extruder dà-sgriubha air am putadh air adhart gu leantainneach leis na sgriothan rothlach. Tha an cuas eas-tharraing air a dhèanamh suas de sgriubha agus baraille, agus bidh meud a’ chuas eas-tharraing a ’dol sìos mean air mhean air taobh an axis. Nuair a thionndaidheas na sgriothan, tha na stuthan air an teannachadh mean air mhean fo ghnìomhachd nan sgriothan agus a’ bharaille, agus bidh an cuideam anns a’ chuas eas-tharraing ag àrdachadh mean air mhean (generally 5-12MPa).
Aig an aon àm, tha na stuthan fo smachd feachd rùsgaidh làidir agus feachd brisidh air a chruthachadh leis a’ ghluasad dàimheach eadar na sgriothan agus am baraille, a bharrachd air eadar na tursan-adhair sgriubha. The shear force and friction force can fully break the agglomerates of pigments, make the pigments uniformly dispersed in the melted carrier, and promote the fusion and compatibility between the pigment, carrier and additives. Faodaidh an fheachd brisidh cuideachd beagan teas a ghineadh, a tha air a chur còmhla ri teasachadh taobh a-muigh a 'bharaille (teasachadh dealain no teasachadh smùid) to make the carrier gradually melt and plasticize.
Mar as trice tha baraille an extruder air a roinn ann 4-6 earrannan smachd teothachd (roinn beathachaidh, earrann leaghaidh, earrann measgachadh, roinn homogenizing, roinn ceann bàs), and the temperature of each section is precisely controlled according to the type of masterbatch (seòrsa neach-giùlain, pigment type). Mar eisimpleir, when processing PE masterbatch, the temperature of the feeding section is 100-120℃, the melting section is 160-180℃, the mixing section is 170-190℃, the homogenizing section is 160-180℃, and the die head section is 150-170℃. Faodaidh an smachd teothachd mionaideach dèanamh cinnteach gu bheil an neach-giùlain air a leaghadh gu tur gun lobhadh teirmeach, agus chan eil na pigmentan air an lobhadh no air an dath.
Bidh sgriubha an extruder dà-sgriubha a’ gabhail ri dealbhadh modular, a dh’ fhaodas diofar eileamaidean sgriubha a chur còmhla gu saor (leithid eileamaidean giùlan, measgachadh eileamaidean, eileamaidean rùsgaidh) a rèir an t-seòrsa masterbatch. Mar eisimpleir, nuair a bhios tu a’ giullachd masterbatch le susbaint àrd de pigment agus cruinneachadh furasta, faodar barrachd eileamaidean measgachaidh agus eileamaidean rùsgaidh a rèiteachadh gus a’ bhuaidh measgachaidh is sgapadh a neartachadh; nuair a bhios tu a’ giullachd masterbatch le deagh fhileantachd, faodar barrachd eileamaidean giùlain a rèiteachadh gus èifeachdas cinneasachaidh a leasachadh.
2.2.5 Extrusion agus cumadh
An làn leaghadh, tha stuth measgaichte agus sgapte air a phutadh gu ceann die an extruder leis na sgriothan. Mar as trice bidh ceann die an extruder masterbatch air a uidheamachadh le grunn thuill bàis cruinn (tha àireamh agus meud nan tuill-bàis air an co-dhùnadh a rèir meud nam pàirtean den masterbatch). The material is extruded from the die head at a high speed to form continuous strip-shaped semi-finished products (the diameter of the strip is usually 2-5mm, a ghabhas atharrachadh a rèir feumalachdan luchd-cleachdaidh).
The temperature of the die head is slightly lower than that of the homogenizing section, which can prevent the material from decomposing due to excessive temperature and ensure the shaping effect of the strip. The extrusion speed is controlled according to the type of masterbatch and the particle size requirement, generally ranging from 1-3m/min. The extrusion pressure should be kept stable (fluctuation within ±0.5MPa), which can ensure the uniform diameter of the strip and the consistency of the masterbatch quality.
2.2.6 Cooling and Solidification
Bithear a’ cur na toraidhean leth-chrìochnaichte cumadh stiallach gu inneal fuarachaidh airson fuarachadh luath agus solidification. Mar as trice is e fuarachadh tanca uisge an dòigh fuarachaidh airson masterbatch, agus tha teòthachd an uisge fuarachaidh air a smachdachadh aig 20-30 ℃. Tha fad an tanca uisge fuarachaidh 3-5 meatairean, agus tha an ùine fuarachaidh 2-4 mionaidean. Faodaidh fuarachadh luath toirt air an stiall daingneachadh gu sgiobalta, cumail suas cumadh agus meud an stiall, agus seachain deformation agus adhesion.
Bu chòir a thoirt fa-near gum bu chòir an astar fuarachaidh a bhith co-ionnan. Ma tha an astar fuarachaidh ro luath, bidh cuideam a-staigh an stiall ro mhòr, agus bidh an stiall brisg agus furasta a bhriseadh aig àm granulation; ma tha an astar fuarachaidh ro shlaodach, bidh an stiall bog agus furasta a chumail, toirt buaidh air buaidh granulation. An dèidh fuarachadh, bu chòir uachdar na stiall a bhith tioram, rèidh agus saor bho builgeanan agus sgàinidhean.
2.2.7 Buain agus Granaidh
An dèidh fuarachadh agus solidification, the strip is sent to a granulator for cutting to form granular masterbatch products. The granulator is equipped with a rotary knife and a fixed knife, and the cutting speed is adjustable (san fharsaingeachd 500-1000 rpm). The particle size of the masterbatch is controlled by adjusting the cutting speed and the speed of the strip conveying. The common particle size of masterbatch is 2-5mm (length and diameter are basically the same), which is convenient for mixing with plastic raw materials during later use.
The granulator should be equipped with a screening device to remove unqualified particles (leithid ro mhòr, too small, agglomerated or broken particles). The qualified particles enter the next process, and the unqualified particles are crushed and recycled (after drying and premixing, they are re-extruded and granulated).
2.2.8 Sgrionadh, Inspection and Packaging
Bithear a’ cur an masterbatch gràinealaichte gu scrion crathaidh airson sgrìonadh gus tuilleadh gràineanan agus neo-chunbhalachd a thoirt air falbh. Tha an scrion crathaidh air a uidheamachadh le scrion ioma-fhilleadh (diofar mheudan mogaill), as urrainn sgrìonadh a-mach mìrean masterbatch de dhiofar shònrachaidhean a rèir feumalachdan teachdaiche.
Às deidh sgrìonadh, feumaidh an masterbatch a dhol tro sgrùdadh càileachd. Tha na nithean sgrùdaidh sa mhòr-chuid a’ toirt a-steach: dath (èideadh, cunbhalachd leis an sampall àbhaisteach), sgapadh (air fhaicinn le miocroscop no dathadh pìos deuchainn), dùmhlachd (deuchainn neart teannachaidh), susbaint taiseachd, cuairteachadh meud gràin, etc. Is e dìreach an masterbatch a choinnicheas ri inbhean càileachd a dh’ fhaodar a phacaigeadh.
Bidh pacadh masterbatch a’ gabhail ri pacadh seulaichte agus dìon-taise (leithid pocannan plastaig fighte le film plastaig a-staigh, pocannan foil aluminium), agus mar as trice tha cuideam pacaidh 25kg/bag no 50kg/bag. The packaging bag is marked with the product name, modail, dath, dùmhlachd, seòrsa neach-giùlain, production date, shelf life, manufacturer and other information. The packaged masterbatch should be stored in a dry, taigh-bathair fionnar is fionnaraichte, a’ seachnadh solas dìreach agus taiseachd, agus tha beatha sgeilp san fharsaingeachd 6-12 mìosan.
2.3 Prìomh fhactaran a bheir buaidh air buaidh eas-tharraing dà-sgriubha Masterbatch
Bidh buaidh eas-tharraing dà-sgriubha a’ toirt buaidh dhìreach air càileachd masterbatch (sgapadh, tinting strength, seasmhachd). Tha grunn nithean ann a tha a’ toirt buaidh air a’ bhuaidh eas-tharraing, sa mhòr-chuid a’ toirt a-steach feartan stuthan amh, co-mheas foirmle, buaidh premixing, crìochan eas-tharraing agus coileanadh uidheamachd. Le bhith a’ maighstireachd nam prìomh nithean sin agus a’ dèanamh atharrachaidhean saidheansail faodaidh sin dèanamh cinnteach à seasmhachd a’ bhuaidh eas-tharraing agus cunbhalachd càileachd toraidh.
2.3.1 Feartan stuthan amh
An seòrsa, meud gràin, tha susbaint taiseachd agus purrachd stuthan amh a’ toirt buaidh mhòr air a ’bhuaidh eas-tharraing. Airson pigmentan, bu chòir meud na gràin a bhith èideadh agus ceart (20-40 mogal), agus bu chòir an ìre cruinneachaidh a bhith ìosal; tha droch sheasamh teas aig pigmentan organach, mar sin bu chòir smachd teann a chumail air an teòthachd eas-tharraing; tha cruas àrd aig pigmentan neo-organach, mar sin bu chòir gum biodh deagh sheasamh caitheamh aig an extruder. Airson luchd-siubhail, bu chòir an ìre leaghaidh agus an teòthachd giollachd a bhith co-chòrdail ris na stuthan amh plastaig targaid, agus bu chòir an co-chòrdalachd le pigmentan a bhith math. Airson stuthan cur-ris, bu chòir an seòrsa agus an dòs a bhith reusanta, and the compatibility with carriers and pigments should be good.
A bharrachd air, the moisture content of raw materials must be strictly controlled below 0.1%; ma tha an taiseachd ro àrd, it will cause bubbles and agglomeration in the masterbatch. Tha purrachd stuthan amh cuideachd glè chudromach; impurities in raw materials will not only affect the product quality, ach cuideachd caith sgriubha agus baraille an extruder.
2.3.2 Co-mheas foirmle
The formula ratio of masterbatch (the ratio of pigment, carrier and additive) is the key to determining the quality of the product. The pigment content should be determined according to the coloring requirements and the type of pigment: high-concentration masterbatch (susbaint pigment 50%-80%) can reduce the addition amount and production cost, but requires better dispersibility; low-concentration masterbatch (susbaint pigment 10%-30%) has better dispersibility, ach tha an t-suim a bharrachd mòr agus tha a’ chosgais toraidh àrd.
Tha dosage de dispersants san fharsaingeachd 1%-5% den dosachadh pigment; bidh cus sgaoilidh a’ leantainn gu droch sgapadh pigmentan, agus bheir cus sgaoilidh buaidh air feartan meacanaigeach an masterbatch agus na toraidhean dathte. Dosage de stuthan cur-ris eile (luchd-coimhid, stabilizers teas, bealaidh) tha san fharsaingeachd 0.5%-3%, a bu chòir a bhith air atharrachadh a rèir an t-seòrsa masterbatch agus giollachd riatanasan. Bu chòir smachd teann a chumail air co-mheas na foirmle, agus bu chòir don mhearachd a bhith taobh a-staigh ± 1%, gus dèanamh cinnteach à cunbhalachd càileachd toraidh eadar batches.
2.3.3 Buaidh Premixing
Is e premixing bunait giollachd eas-tharraing. Bidh èideadh premixing a’ toirt buaidh dhìreach air buaidh measgachadh agus sgapadh pigmentan aig àm eas-tharraing. Ma tha an premixing neo-chothromach, chan urrainnear na pigmentan a chumail gu co-ionnan ri uachdar an neach-giùlain, mar thoradh air cruinneachadh ionadail de pigmentan, measgachadh neo-chòmhnard de stuthan rè eas-tharraing, and reduced product dispersibility.
Gus dèanamh cinnteach à buaidh premixing, tha e riatanach smachd a chumail air astar measgachadh (800-1200 rpm), measgachadh ùine (5-10 mionaidean) and mixing temperature (40-60℃). Airson masterbatch le susbaint àrd de pigment, faodar an ùine premixing a leudachadh gu h-iomchaidh, and the dispersant can be added first and mixed with the pigment, then mixed with the carrier and other additives. A bharrachd air, the premixed mixture should be inspected; if there are obvious pigment agglomerates, it should be crushed and remixed.
2.3.4 Paramadairean eas-tharraing
Is e paramadairean eas-tharraing na factaran as cudromaiche a bheir buaidh air a’ bhuaidh eas-tharraing, sa mhòr-chuid a’ toirt a-steach astar sgriubha, teòthachd eas-tharraing agus cuideam eas-tharraing.
- Luas sgriubha: The screw speed of twin-screw extruders for masterbatch processing generally ranges from 200 gu 800 rpm. Mar as àirde an astar sgriubha, mar as motha am feachd rùsgaidh agus an fheachd brisidh a gheibh na stuthan, the better the mixing and dispersing effect of pigments, agus mar as àirde an èifeachdas toraidh. Ge-tà, ma tha astar an sgriubha ro àrd, tha ùine còmhnaidh nan stuthan anns a’ chuas eas-tharraing ro ghoirid, resulting in incomplete melting of the carrier, measgachadh gu leòr de stuthan, and uneven dispersibility; ma tha astar an sgriubha ro ìosal, chan eil an fheachd rùsgaidh agus an fheachd brisidh gu leòr, the pigment agglomerates cannot be fully broken, agus tha an èifeachdas toraidh ìosal.
- The screw speed should be adjusted according to the type of masterbatch: for masterbatch with high pigment content and easy agglomeration (such as black masterbatch, white masterbatch), a higher screw speed (500-800 rpm) is needed to ensure the uniform dispersion of pigments; for masterbatch with organic pigments (poor heat resistance), a moderate screw speed (300-500 rpm) is needed to avoid overheating and pigment decomposition.
- Teòthachd extrusion: The extrusion temperature is the key to ensuring the melting of the carrier and the stability of the pigment. The temperature of each section of the barrel and die head must be precisely controlled according to the type of masterbatch (seòrsa neach-giùlain, pigment type). Tha teòthachd an earrann beathachaidh nas ìsle (beagan nas àirde na an teòthachd tiormachaidh de na stuthan amh), a tha sa mhòr-chuid airson casg a chuir air na stuthan bho bhith a’ còcaireachd agus dèanamh cinnteach à biadhadh rèidh; tha teòthachd na h-earrainn leaghaidh meadhanach, which is mainly to promote the melting and plasticization of the carrier; tha teòthachd na h-earrainn measgachadh nas àirde, a tha sa mhòr-chuid airson a’ bhuaidh rùsgaidh is measgachaidh a neartachadh, and promote the uniform dispersion of pigments; tha teòthachd na h-earrainn homogenizing beagan nas ìsle na an roinn measgachadh, which is mainly to ensure the uniform temperature and viscosity of the materials, and avoid thermal decomposition; the temperature of the die head section is slightly lower than the homogenizing section, which is to ensure the shaping effect of the strip.
- The temperature control precision should reach ±1℃. Mar eisimpleir, nuair a bhios tu a’ làimhseachadh masterbatch PP le pigmentan organach, tha teòthachd gach earrann: earrann beathachaidh 110-130 ℃, earrann leaghadh 170-190 ℃, earrann measgachadh 180-200 ℃, homogenizing earrann 170-190 ℃, roinn ceann bàsachadh 160-180 ℃. Ma tha an teòthachd ro àrd, bidh am pigment a’ lobhadh agus bidh an neach-giùlain a’ dol sìos; ma tha an teòthachd ro ìosal, cha bhith an neach-giùlain air a leaghadh gu tur, agus chan urrainn am pigment a bhith air a sgaoileadh gu co-ionnan.
- Extrusion Brùthadh: Mar as trice tha an cuideam eas-tharraing de eas-tharraing dà-sgriubha masterbatch a’ dol bho 5 gu 12MPa. Tha an cuideam anns a’ chuas eas-tharraing air a dhearbhadh sa mhòr-chuid le co-mheas teannachaidh an sgriubha, meud an toll-bàis agus astar an sgriubha. Mar as àirde an cuideam eas-tharraing, 's ann as fheàrr a bhios buaidh measgachadh agus sgapadh stuthan, agus mar is dùmhail an stiall. Ge-tà, ma tha an cuideam ro àrd, àrdaichidh e caitheamh lùtha agus caitheamh an uidheim, agus eadhon a 'toirt air a' cheann bàs bacadh; ma tha an cuideam ro ìosal, chan urrainn na stuthan a bhith làn dhlùthadh agus measgachadh, tha an stiall sgaoilte, agus tha an sgapadh truagh.
- Bu chòir an cuideam eas-tharraing atharrachadh a rèir an seòrsa masterbatch agus meud ceann die: airson masterbatch le susbaint àrd de pigment agus droch fhileantachd, tha feum air cuideam eas-tharraing nas àirde; airson masterbatch le deagh fluidity, tha cuideam meadhanach eas-tharraing gu leòr. The extrusion pressure should be kept stable, agus bu chòir an atharrachadh a bhith taobh a-staigh ± 0.5MPa, gus dèanamh cinnteach à trast-thomhas èideadh an stiall agus cunbhalachd càileachd masterbatch.
2.3.5 Coileanadh Uidheam
Bidh coileanadh an extruder dà-sgriubha a’ dearbhadh gu dìreach a ’bhuaidh eas-tharraing. Tha prìomh chomharran coileanaidh an extruder gabhail a-steach measgachadh agus sgapadh comas, mionaideachd smachd teothachd, strì an aghaidh caitheamh, comas giùlain agus comas smachd tuigseach. Sreath slàn de extruders Zhuoyue (HTS BASIC / PLUS / SUPER, ZTE, HTE) air an dealbhadh gu sònraichte airson giollachd masterbatch, le coileanadh sàr-mhath anns na taobhan sin, as urrainn coinneachadh gu h-èifeachdach ri feumalachdan giollachd diofar sheòrsaichean masterbatch.
3. Sreath slàn Zhuoyue Extruders: Fuasglaidhean proifeasanta airson pròiseasadh Masterbatch
Tha Zhuoyue air a bhith an sàs anns an rannsachadh o chionn fhada, leasachadh agus cinneasachadh àrd-choileanadh dà-sgriubha extruders, agus tha e air eòlas beairteach a chruinneachadh ann an raon giollachd masterbatch. A rèir feartan giollachd masterbatch (susbaint àrd pigment, cruinneachadh furasta de pigmentan, riatanasan smachd teothachd teann, riatanasan àrd caitheamh caitheamh) agus feumalachdan eadar-dhealaichte luchd-saothrachaidh (diofar ìrean toraidh, diofar sheòrsaichean de masterbatch, different application fields), Zhuoyue has launched a full series of extruders suitable for masterbatch processing, gabhail a-steach sreath HTS BASIC, HTS PLUS series, HTS SUPER series, ZTE series and HTE series. Each series has its own performance characteristics and targeted adaptation scenarios, which can provide personalized and efficient processing solutions for masterbatch manufacturers of different scales.
3.1 Core Advantages of Zhuoyue’s Extruders for Masterbatch Processing
Whether it is the high-end HTS SUPER series or the cost-effective ZTE series, all Zhuoyue’s extruders have the following core advantages, which are specially optimized for masterbatch processing, ensuring high-quality, cinneasachadh èifeachdach agus seasmhach:
3.1.1 Buaidh measgachadh is sgapadh sàr-mhath
The core requirement of masterbatch processing is the uniform dispersion of pigments. Bidh a h-uile inneal-sgaoilidh dà-sgriubha Zhuoyue a’ gabhail ri structar co-chuairteachaidh eadar-mheadhanach, le pitch sgriubha reusanta, dealbhadh co-mheas luaidhe agus teannachaidh. Faodaidh eadar-fhilleadh agus cuairteachadh nan sgriubhaichean càraid feachd rùsgaidh làidir agus feachd glùineachaidh a ghineadh, which can fully break the agglomerates of pigments (eadhon cruinneachaidhean beaga de 100 μm gu h-àrd), agus dèan na pigmentan air an sgapadh gu cothromach anns a’ ghiùlan. Faodaidh èideadh measgachadh an extruders ruighinn barrachd air 95%, a tha mòran nas àirde na an fheadhainn àbhaisteach le dà sgriubha extruders (85%-90%).
A bharrachd air, bidh na sgriothan de gach sreath de extruders a’ gabhail ri dealbhadh modular, a tha comasach air diofar sheòrsaichean de eileamaidean sgriubha a chur còmhla gu saor (a' giùlan eileamaidean, measgachadh eileamaidean, eileamaidean rùsgaidh) a rèir an t-seòrsa masterbatch (leithid masterbatch dath, white masterbatch, maighstir dubh) agus feartan pigment.
