Polivinielchloried (PVC) is een van die sintetiese polimere wat die meeste in die wêreld gebruik word, gewaardeer vir sy uitstekende veelsydigheid, kostedoeltreffendheid, chemiese weerstand, en meganiese eienskappe. Dit het byna elke terrein van die moderne lewe binnegedring, van konstruksie en verpakking tot motor, elektriese en elektroniese industrieë. Egter, suiwer PVC-hars het inherente beperkings soos swak termiese stabiliteit, onvoldoende impakweerstand, en smal verwerkingsvenster, wat die toepassing daarvan in hoëprestasie-scenario's beperk. Om hierdie tekortkominge te oorkom en die toepassing daarvan uit te brei, PVC-mengselmengseltegnologie het na vore getree as 'n sleutelskakel in die PVC-verwerkingsbedryf. Hierdie tegnologie behels die vermenging van PVC-hars met verskeie bymiddels (soos weekmakers, stabiliseerders, vullers, smeermiddels, en wysigers) deur professionele toerusting, gevolg deur granulering of direkte gietvorm, om PVC-verbindings te verkry met pasgemaakte eienskappe wat aan spesifieke toepassingsvereistes voldoen.
Ons het diepgaande en unieke ervaring opgedoen op die gebied van PVC-verbindingsmengsel en verwerking. Oor die jare, ons is daartoe verbind om PVC-verwerkingstegnologie na te vors en te optimaliseer, en het geteikende ekstrusie-oplossings vir verskillende tipes PVC-materiale ontwikkel (insluitend stewige PVC, buigsame PVC, en gewysigde PVC). Ons tegniese span het 'n diep begrip van die verwerkingseienskappe van verskeie PVC-harse en bymiddels, en kan pasgemaakte oplossings verskaf volgens die spesifieke behoeftes van kliënte. Of dit nou 'n standaard PVC-produk is of 'n spesiale aangepaste PVC-verbinding met streng prestasievereistes, ons kan stabiele en betroubare verwerkingsgehalte verseker deur wetenskaplike prosesontwerp en gevorderde toerustingkonfigurasie.
1. Oorsig van PVC-mengselmengseltegnologie
1.1 Basiese beginsels van PVC-mengselmenging
PVC-mengselvermenging is 'n komplekse fisiese en chemiese proses wat vaste vermenging integreer, smelt, plastiseer, skeer, en homogenisering. Die kerndoel is om verskeie bymiddels eenvormig in die PVC-harsmatriks te versprei, elimineer interne defekte (soos lugborrels, agglomerasie, en ongelyke komponentverspreiding) van die mengsel, en verbeter die plastiseringsgraad en verwerkingsprestasie van die verbinding, om 'n stewige grondslag te lê vir die daaropvolgende gietverwerking (soos ekstrusie, spuitgiet, kalandering) en die finale produkprestasie.
Die mengproses van PVC-verbindings word gewoonlik in twee fases verdeel: droë meng en smelt meng. Droë vermenging is die aanvanklike stadium, wat hoofsaaklik behels die vermenging van PVC-harspoeier met verskeie bymiddels (soos stabiliseerders, smeermiddels, vullers, weekmakers vir buigsame PVC) in 'n hoëspoedmenger. Die doel van droë vermenging is om die bymiddels eenvormig aan die oppervlak van PVC-harspartikels te laat kleef deur die werking van meganiese roer en wrywingshitte, en om die mengsel tot 'n sekere temperatuur voor te verhit, wat bevorderlik is vir die daaropvolgende smeltplastisering. Smeltvermenging is die sleutelstadium, wat gewoonlik in ekstrueerders of interne mengers voltooi word. Onder die gekombineerde werking van eksterne verwarming en skuifkrag wat deur die skroef gegenereer word (of rotor), die PVC-harspartikels word geleidelik gesmelt en geplastiseer, en die bymiddels word verder op molekulêre vlak in die harsmatriks versprei om 'n eenvormige en stabiele smeltstelsel te vorm. Uiteindelik, die smelt word geëxtrudeer, gegranuleer of direk tot produkte gevorm word.
1.2 Sleutelbymiddels vir PVC-mengselmengsels
Die werkverrigting van PVC-verbindings word grootliks deur die tipe bepaal, dosering en meng effek van bymiddels. Verskillende bymiddels speel verskillende rolle in die meng- en verwerkingsproses en die finale produkte. Die volgende is die belangrikste bymiddels wat algemeen gebruik word in die meng van PVC-verbindings:
1.2.1 Stabiliseerders:
PVC-hars is geneig tot termiese agteruitgang by hoë temperature (bo 100 ℃), wat tot verkleuring sal lei (van wit na geel, bruin, selfs swart), vermindering van meganiese eienskappe en verlies aan gebruikswaarde. Daarom, stabiliseerders moet by PVC-verbindings gevoeg word om hul termiese stabiliteit te verbeter. Algemene PVC-stabiliseerders sluit in loodgebaseerde stabiliseerders, kalsium-sink saamgestelde stabiliseerders, barium-kadmium stabiliseerders, en organiese tinstabiliseerders. Onder hulle, kalsium-sink saamgestelde stabiliseerders word wyd gebruik as gevolg van hul omgewingsvriendelikheid, nie-toksisiteit, en goeie termiese stabiliteit, wat in lyn is met die wêreldwye omgewingsbeskermingsvereistes vir plastiekprodukte.
1.2.2 Weekmakers:
Weekmakers word hoofsaaklik in buigsame PVC-verbindings gebruik om die glasoorgangstemperatuur van PVC-hars te verminder, verbeter sy buigsaamheid, taaiheid en verwerkbaarheid. Hulle kan die molekulêre ketting van PVC binnedring, verswak die intermolekulêre krag, maak die molekulêre ketting maklik om te beweeg, maak dus die PVC-verbinding sag en maklik om te verwerk. Algemene weekmakers sluit dioktielftalaat in (DOP), dioktieltereftalaat (DOTP), diisononielftalaat (DINP), en epoksie soja-olie. Onder hulle, DOTP het die voordele van omgewingsbeskerming, lae wisselvalligheid, en goeie verenigbaarheid met PVC, en word wyd gebruik in hoëgraadse buigsame PVC-produkte (soos mediese slange, voedselverpakkingsfilms).
1.2.3 Vullers:
Vullers word by PVC-verbindings gevoeg om produksiekoste te verminder, verbeter die styfheid, hardheid, slytasieweerstand en dimensionele stabiliteit van produkte, en pas die digtheid van verbindings aan. Algemene vullers sluit kalsiumkarbonaat in (ligte kalsiumkarbonaat, swaar kalsiumkarbonaat), talkpoeier, kaolien, en koolstofswart. Kalsiumkarbonaat is die vulstof wat die meeste gebruik word as gevolg van sy lae prys, oorvloedige bronne, en goeie verenigbaarheid met PVC. Die byvoeging van 'n gepaste hoeveelheid kalsiumkarbonaat kan nie net koste verminder nie, maar ook die verwerkingsvloeibaarheid en impakweerstand van PVC-verbindings verbeter.
1.2.4 Smeermiddels:
Smeermiddels word gebruik om die wrywing tussen PVC-harspartikels te verminder, tussen die mengsel en die toerusting (soos die binnewand van die menger, die skroef van die ekstruder), en tussen die smelt en die vorm, om die verwerkingsvloeibaarheid van die verbinding te verbeter, verhoed dat die materiaal aan die toerusting kleef, en verseker die gladde vordering van die meng- en gietproses. Algemene smeermiddels sluit steariensuur in, kalsiumstearaat, sinkstearaat, en paraffien. Volgens die aksiemeganisme, smeermiddels kan verdeel word in interne smeermiddels en eksterne smeermiddels. Interne smeermiddels kan die wrywing tussen PVC-molekulêre kettings verminder, verbeter die plastiseringsdoeltreffendheid; eksterne smeermiddels kan 'n smeerfilm op die oppervlak van die materiaal vorm, verminder die wrywing tussen die materiaal en die toerusting.
1.2.5 Wysigers:
Wysigingsmiddels word bygevoeg om spesifieke eienskappe van PVC-verbindings te verbeter, soos impakweerstand, hitte weerstand, en deursigtigheid. Algemene wysigers sluit in akrilonitril-butadieen-stireen (ABS) hars, metielmetakrilaat-butadieen-stireen (MBS) hars, gechloreerde poliëtileen (CPE), en akrielhars. Byvoorbeeld, MBS-hars kan die impakweerstand van rigiede PVC-verbindings aansienlik verbeter, wat hulle geskik maak vir die vervaardiging van plastiekpype, profiele, en spuitgietonderdele wat hoë taaiheid vereis.
1.3 Belangrikheid van PVC-verbindingsmodifikasie en -granulering
In die meeste PVC-verwerkingscenario's, PVC-hars moet eers gemodifiseer en gegranuleer word voor die daaropvolgende gietverwerking. Dit is omdat gewysigde granulering baie ooglopende voordele kan inhou:
Eerstens, dit verbeter die plastiseringsgraad van PVC. Deur die gekombineerde werking van droë vermenging en smeltvermenging in die granuleringsproses, PVC-harspartikels word volledig gesmelt en geplastiseer, en bymiddels word eenvormig versprei, wat die probleme van onvoldoende plastisering vermy, ongelyke komponentverspreiding, en interne defekte in direkte giet van suiwer hars, verbeter dus die verwerkingsprestasie van die materiaal.
Tweedens, dit vereenvoudig die daaropvolgende verwerkingsproses. Die PVC-korrels na modifikasie en granulering het eenvormige deeltjiegrootte, goeie vloeibaarheid, en stabiele prestasie. Hulle kan direk in ekstrusie gebruik word, spuitgiet, kalandering, blaasvorm en ander gietprosesse sonder bykomende vermenging of voorverwerking, wat die produksieproses verminder, verbeter produksiedoeltreffendheid, en verminder die arbeidsintensiteit van operateurs.
Derde, dit verseker die stabiliteit van produkkwaliteit. Die werkverrigting van gemodifiseerde PVC-korrels is relatief stabiel, wat die fluktuasie van produkprestasie kan vermy wat veroorsaak word deur ongelyke vermenging van bymiddels in direkte giet, verseker dus die konsekwentheid van produkkwaliteit en verminder die produkdefektesyfer.
Vierde, dit brei die toepassingsomvang van PVC uit. Deur doelgerigte wysiging (soos om verskillende wysigers by te voeg, weekmakers, en vullers), PVC-verbindings met verskillende eienskappe kan voorberei word, wat aan die vereistes van verskillende toepassingsvelde kan voldoen. Byvoorbeeld, stewige PVC-korrels met hoë styfheid en slagweerstand kan in die vervaardiging van plastiekpype en -profiele gebruik word; buigsame PVC-korrels met goeie buigsaamheid en sagtheid kan in die vervaardiging van slange gebruik word, kabels, en verpakkingsfilms; vlamvertragende PVC-korrels kan gebruik word in die vervaardiging van elektriese en elektroniese produkte.
Dit moet beklemtoon word dat vir PVC produkte met spesiale vereistes (soos hoë temperatuur weerstand, weerstand teen korrosie, vlamvertraging, en deursigtigheid) en PVC-gemodifiseerde formules, ons voer altyd pasgemaakte ontwikkeling uit volgens die spesifieke behoeftes van kliënte. Ons tegniese span sal in-diepte kommunikasie met kliënte voer om hul produkgebruikscenario's te verstaan, prestasievereistes, en produksiekoste, en ontwerp dan die mees geskikte gewysigde formule en mengproses om te verseker dat die vervaardigde PVC-verbindings ten volle aan die kliënt se verwagtinge kan voldoen.
2. Ekstrusietoerusting vir PVC-mengselmengsel en granulering
Ekstruderers is die kerntoerusting vir die vermenging van PVC-verbindings, granulasie, en gietverwerking. Hulle speel 'n deurslaggewende rol in die smeltplastisering, skeer vermenging, en ekstrusie giet van PVC mengsels. Die werkbeginsel van ekstrueerders is om eksterne kragoordrag te gebruik om die skroef te laat draai, en gebruik die hitte-oordrag van eksterne verwarmingselemente en die skuifhitte wat deur die draai van die skroef gegenereer word om die soliede vervoer te realiseer, verdigting, smelt, skeer vermenging, en ekstrusie van PVC-materiaal. As 'n belangrike toerusting in plastiek giet verwerking, ekstrueerders word wyd gebruik in die granulering van PVC-verbindings en die giet van verskeie PVC-produkte, en 'n onvervangbare posisie in die PVC-verwerkingsbedryf beklee.
Volgens die struktuur en werkverrigting van ekstrueerders, ons het twee reekse ekstrueerders ontwikkel wat geskik is vir die meng en granulering van PVC-verbindings, naamlik die ZTE MODEL reeks en die HTE reeks. Hierdie twee reekse ekstrueerders het hul eie eienskappe en voordele, en kan voldoen aan die verskillende behoeftes van kliënte vir produksiekapasiteit, produk kwaliteit, en kostebeheer.
2.1 ZTE MODEL Ekstruder: Koste-effektiewe keuse vir algemene PVC-materiale

In terme van strukturele ontwerp, die ZTE MODEL-ekstruder neem 'n enkelskroefstruktuur aan, wat 'n eenvoudige struktuur het, betroubare werking, en maklike instandhouding. Die skroef is gemaak van hoë-gehalte legeringstaal,经过 presisie bewerking en hittebehandeling, wat hoë hardheid het, slytasie weerstand, en weerstand teen korrosie, en kan die lewensduur van die skroef effektief verleng. Die loop is ook gemaak van hoë-gehalte legeringstaal, met 'n ingeboude verwarmingselement en 'n verkoelingstelsel, wat die temperatuur van die vat akkuraat kan beheer, verseker dat die PVC-mengsel ten volle gesmelt en geplastiseer is, en vermy termiese agteruitgang van die materiaal as gevolg van oormatige temperatuur.
In terme van prestasie parameters, die ZTE MODEL-ekstruder het 'n wye reeks verstelbare spoed, wat die skroefspoed kan aanpas volgens die tipe PVC-materiaal en die vereistes van die granulasieproses, om sodoende die produksiekapasiteit en die mate van skuifmenging te beheer. Die ekstrusiedruk van die ekstruder is stabiel, wat die eenvormige deeltjiegrootte van die geëxtrudeerde korrels en goeie vloeibaarheid kan verseker. Die produksiekapasiteit van die ZTE MODEL ekstruder wissel van 50kg/h tot 200kg/h, wat geskik is vir klein en mediumgrootte ondernemings en kliënte met matige produksievraag.
Daarby, die ZTE MODEL-ekstruder is toegerus met 'n volledige beheerstelsel, wat 'n PLC-beheerpaneel aanneem, met eenvoudige bediening en duidelike vertoning.

Dit is veral geskik vir die vermenging en granulering van hoëgraadse gemodifiseerde PVC-verbindings (soos hoë-impak PVC, vlamvertragende PVC, deursigtige PVC) en PVC-produkte met streng prestasievereistes.
In terme van strukturele ontwerp, die HTE-reeks-ekstruder neem 'n dubbelskroefstruktuur aan, wat ooglopende voordele in vergelyking met die enkelskroef-ekstruder in terme van skuifmenging inhou, plastisering doeltreffendheid, en produksievermoë. Die dubbelskroef kan sterk skuifkrag en mengeffek tydens rotasie genereer, wat die PVC-mengsel en bymiddels meer eenvormig gemeng kan maak, en die plastiseringsgraad is hoër, verbeter dus die werkverrigting van die PVC-verbinding. Volgens die vorm van die skroef, die dubbelskroef-ekstruder kan verdeel word in koniese dubbelskroef-ekstruder en parallelle dubbelskroef-ekstruder. Onder hulle, die koniese dubbelskroef-ekstruder is 'n ideale keuse vir stywe PVC-verbindingsmengsel en -granulering.
The conical twin-screw extruder in the HTE series has a unique conical screw design, with a large screw diameter at the feeding end and a small screw diameter at the extrusion end. This design can make the PVC mixture gradually compressed in the process of conveying, and the shear force gradually increases, which is conducive to the melting and plasticization of rigid PVC resin (which has high viscosity and requires strong shear force for plasticization). Terselfdertyd, the conical twin-screw extruder has good self-cleaning performance, which can avoid the accumulation of material in the screw and barrel, reduce the waste of material, and ensure the stability of the production process.
In terms of material selection, the screw and barrel of the HTE series extruder are made of high-quality wear-resistant and corrosion-resistant alloy steel,经过 special surface treatment (such as nitriding treatment), which further improves the hardness and wear resistance of the screw and barrel, and can adapt to the mixing and granulation of PVC compounds containing fillers (soos kalsiumkarbonaat) and corrosive additives, prolonging the service life of the equipment.
In terms of performance advantages, the HTE series extruder has the characteristics of high production capacity, lae energieverbruik, and good product quality. Compared with the ZTE MODEL extruder, the HTE series extruder can increase the production capacity by 30%-50% under the same power condition, and the energy consumption per unit product can be reduced by 20%-30%, which can effectively reduce the production cost of customers and improve the market competitiveness of their products. Terselfdertyd, the HTE series extruder has a more precise temperature control system and speed control system, which can accurately control the plasticization temperature, shear speed, and extrusion pressure of the PVC mixture, ensuring that the performance of the produced PVC granules is stable and uniform, and meeting the strict requirements of high-end products.
Daarby, the HTE series extruder is equipped with an advanced intelligent control system, which adopts a touch screen control panel and can realize real-time monitoring and adjustment of the production process. The control system has functions such as fault alarm, parameter memory, and automatic shutdown, which can effectively improve the safety and reliability of the production process, reduce the labor intensity of operators, and improve production efficiency. The HTE series extruder can also be matched with high-end auxiliary equipment (such as precision high-speed mixers, air-cooled pelletizers, and automatic packaging machines) to form an automatic PVC compound granulation production line, realizing the integration of feeding, vermenging, plastiseer, ekstrudeer, granuleer, verkoeling, en verpakking, further improving production efficiency and product quality.
The HTE series extruder is widely used in the production of high-grade PVC compounds, such as high-impact PVC pipe granules, flame-retardant PVC cable granules, transparent PVC packaging granules, and medical PVC granules. It is a high-performance and energy-saving solution for customers who pursue high product quality, hoë produksiedoeltreffendheid, and low energy consumption.
2.3 Key Considerations in Selecting PVC Extruders

2.3.2 Produksie kapasiteit:
Customers need to select the extruder with appropriate production capacity according to their own production scale and market demand. If the production demand is small (less than 100kg/h), the ZTE MODEL extruder is suitable; if the production demand is large (more than 100kg/h), the HTE series extruder is more suitable.
2.3.3 Product Quality Requirements:
If the customer’s products have strict requirements on performance (soos impakweerstand, deursigtigheid, vlamvertraging), the HTE series extruder with high plasticization efficiency and uniform mixing effect should be selected; if the product quality requirements are general, the ZTE MODEL extruder with stable performance and high cost performance can be selected.
2.3.4 Energy Consumption and Maintenance Cost:
Energy consumption and maintenance cost are important factors affecting the long-term production cost of customers. The HTE series extruder has the advantage of low energy consumption per unit product, but the initial investment is relatively high; the ZTE MODEL extruder has a lower initial investment and maintenance cost, which is suitable for customers with limited budget.
2.3.5 Compatibility with Auxiliary Equipment:
The selected extruder should be compatible with the existing auxiliary equipment (such as mixers, pelletiseerders, and conveyors) om 'n volledige produksielyn te vorm, avoiding the problem of equipment mismatch affecting production efficiency.
Our professional technical team can provide one-stop consulting and selection services for customers. According to the customer’s specific needs, we will recommend the most suitable extruder model and provide customized equipment configuration and process design to help customers achieve the best production effect with the most reasonable cost.
