Polüvinüülkloriid (PVC) on üks enim kasutatavaid sünteetilisi polümeere maailmas, hinnatud selle suurepärase mitmekülgsuse tõttu, tasuvus, keemiline vastupidavus, ja mehaanilised omadused. See on tunginud peaaegu igasse kaasaegse elu valdkonda, ehitusest ja pakkimisest autotööstuseni, elektri- ja elektroonikatööstus. Siiski, puhtal PVC-vaigul on omad piirangud, näiteks halb termiline stabiilsus, ebapiisav löögikindlus, ja kitsas töötlemisaken, mis piiravad selle rakendamist suure jõudlusega stsenaariumide korral. Nende puuduste ületamiseks ja selle rakendusala laiendamiseks, PVC segude segamise tehnoloogia on kujunenud PVC töötleva tööstuse võtmelüliks. See tehnoloogia hõlmab PVC vaigu segamist erinevate lisanditega (nagu plastifikaatorid, stabilisaatorid, täiteained, määrdeained, ja modifikaatorid) professionaalsete seadmete kaudu, järgneb granuleerimine või otsevormimine, et saada kohandatud omadustega PVC-ühendeid, mis vastavad konkreetsetele kasutusnõuetele.
Oleme kogunud põhjalikud ja ainulaadsed kogemused PVC segude segamise ja töötlemise valdkonnas. Aastate jooksul, oleme pühendunud PVC töötlemistehnoloogiate uurimisele ja optimeerimisele, ja on välja töötanud sihipärased ekstrusioonilahendused erinevat tüüpi PVC materjalide jaoks (sealhulgas jäik PVC, painduv PVC, ja modifitseeritud PVC). Meie tehnilisel meeskonnal on sügav arusaam erinevate PVC vaikude ja lisandite töötlemisomadustest, ja suudab pakkuda kohandatud lahendusi vastavalt klientide konkreetsetele vajadustele. Olgu see standardne PVC toode või spetsiaalne modifitseeritud PVC segu, millel on ranged toimivusnõuded, saame tagada stabiilse ja usaldusväärse töötlemise kvaliteedi teadusliku protsessi kavandamise ja täiustatud seadmete konfiguratsiooni kaudu.
1. Ülevaade PVC segamistehnoloogiast
1.1 PVC segude segamise põhiprintsiibid
PVC segu segamine on keeruline füüsikaline ja keemiline protsess, mis ühendab tahke aine segamise, sulamine, plastifikatsioon, pügamine, ja homogeniseerimine. Põhieesmärk on erinevate lisandite ühtlane hajutamine PVC vaigumaatriksisse, kõrvaldada sisemised vead (nagu õhumullid, linnastu, ja komponentide ebaühtlane jaotus) segust, ja parandada ühendi plastifitseerimisastet ja töötlemisvõimet, et luua tugev alus järgnevaks vormimistöötlemiseks (nagu ekstrusioon, survevalu, kalandreerimine) ja lõpptoote jõudlus.
PVC-ühendite segamisprotsess jaguneb tavaliselt kaheks etapiks: kuivsegamine ja sulasegamine. Kuivsegamine on esialgne etapp, mis hõlmab peamiselt PVC vaigupulbri segamist erinevate lisanditega (nagu stabilisaatorid, määrdeained, täiteained, elastse PVC plastifikaatorid) kiires mikseris. Kuivsegamise eesmärk on mehaanilise segamise ja hõõrdesoojuse toimel panna lisandid ühtlaselt PVC-vaiguosakeste pinnale., ja eelsoojendage segu teatud temperatuurini, mis soodustab järgnevat sulati plastifikatsiooni. Sula segamine on võtmeetapp, mis tavaliselt täidetakse ekstruuderites või sisesegistites. Kruvi tekitatud välise kuumutamise ja nihkejõu koosmõjul (või rootor), PVC vaigu osakesed sulavad ja plastifitseeritakse järk-järgult, ja lisandid hajutatakse edasi vaigumaatriksisse molekulaarsel tasemel, et moodustada ühtlane ja stabiilne sulamissüsteem. Lõpuks, sula pressitakse välja, granuleeritud või otse toodeteks vormitud.
1.2 Peamised lisandid PVC segamiseks
PVC-ühendite toimivuse määrab suuresti tüüp, lisaainete doseerimine ja segamise toime. Erinevad lisandid mängivad segamis- ja töötlemisprotsessis ning lõpptoodetes erinevat rolli. Järgmised on peamised lisandid, mida tavaliselt kasutatakse PVC segude segamisel:
1.2.1 Stabilisaatorid:
PVC vaik on kõrgel temperatuuril termiliselt lagunev (üle 100 ℃), mis toob kaasa värvimuutuse (valgest kollaseks, pruun, isegi must), mehaaniliste omaduste vähenemine ja kasutusväärtuse kadu. Seetõttu, PVC-ühenditele tuleb lisada stabilisaatoreid, et parandada nende termilist stabiilsust. Tavaliste PVC stabilisaatorite hulka kuuluvad pliipõhised stabilisaatorid, kaltsium-tsink komposiitstabilisaatorid, baarium-kaadmium stabilisaatorid, ja orgaanilised tina stabilisaatorid. Nende hulgas, kaltsium-tsink komposiitstabilisaatoreid kasutatakse laialdaselt nende keskkonnasõbralikkuse tõttu, mittetoksilisus, ja hea termiline stabiilsus, mis on kooskõlas plasttoodete ülemaailmsete keskkonnakaitsenõuetega.
1.2.2 Plastifikaatorid:
Plastifikaatoreid kasutatakse peamiselt elastsetes PVC-ühendites PVC-vaigu klaasistumistemperatuuri vähendamiseks, parandada selle paindlikkust, sitkus ja töödeldavus. Nad võivad tungida PVC molekulaarsesse ahelasse, nõrgendada molekulidevahelist jõudu, muudab molekulaarahela hõlpsasti liigutatavaks, muutes PVC segu pehmeks ja kergesti töödeldavaks. Levinud plastifikaatorite hulka kuuluvad dioktüülftalaat (DOP), dioktüültereftalaat (DOTP), diisononüülftalaat (DINP), ja epoksü sojaõli. Nende hulgas, DOTP-l on keskkonnakaitse eelised, madal volatiilsus, ja hea ühilduvus PVC-ga, ja seda kasutatakse laialdaselt kõrgekvaliteedilistes elastsetes PVC-toodetes (nagu meditsiinivoolikud, toiduainete pakkimiskiled).
1.2.3 Täiteained:
Tootmiskulude vähendamiseks lisatakse PVC-ühenditele täiteaineid, parandada jäikust, kõvadus, kulumiskindlus ja toodete mõõtmete stabiilsus, ja reguleerige ühendite tihedust. Levinud täiteainete hulka kuuluvad kaltsiumkarbonaat (kerge kaltsiumkarbonaat, raske kaltsiumkarbonaat), talgipulber, kaoliin, ja tahma. Kaltsiumkarbonaat on oma madala hinna tõttu kõige laialdasemalt kasutatav täiteaine, rikkalikud allikad, ja hea ühilduvus PVC-ga. Sobiva koguse kaltsiumkarbonaadi lisamine ei vähenda mitte ainult kulusid, vaid parandab ka PVC-ühendite töötlemise voolavust ja löögikindlust..
1.2.4 Määrdeained:
Määrdeaineid kasutatakse PVC-vaiguosakeste vahelise hõõrdumise vähendamiseks, segu ja seadmete vahel (nagu segisti sisesein, ekstruuderi kruvi), ning sulatise ja vormi vahel, et parandada ühendi töötlemise voolavust, vältida materjali kleepumist seadme külge, ning tagavad segamis- ja vormimisprotsessi sujuva edenemise. Levinud määrdeainete hulka kuuluvad steariinhape, kaltsiumstearaat, tsinkstearaat, ja parafiin. According to the action mechanism, lubricants can be divided into internal lubricants and external lubricants. Internal lubricants can reduce the friction between PVC molecular chains, improve the plasticization efficiency; external lubricants can form a lubricating film on the surface of the material, reduce the friction between the material and the equipment.
1.2.5 Modifiers:
Modifiers are added to improve specific properties of PVC compounds, such as impact resistance, kuumakindlus, and transparency. Common modifiers include acrylonitrile-butadiene-styrene (ABS) vaik, methyl methacrylate-butadiene-styrene (MBS) vaik, chlorinated polyethylene (CPE), and acrylic resin. Näiteks, MBS resin can significantly improve the impact resistance of rigid PVC compounds, making them suitable for the production of plastic pipes, profiilid, and injection molding parts that require high toughness.
1.3 PVC-ühendite modifitseerimise ja granuleerimise tähtsus
Enamikus PVC töötlemise stsenaariumides, PVC-vaiku tuleb enne järgnevat vormimistöötlust esmalt modifitseerida ja granuleerida. Seda seetõttu, et modifitseeritud granuleerimine võib tuua palju ilmseid eeliseid:
Esiteks, see parandab PVC plastifitseerimisastet. Kuivsegamise ja sulasegamise kombineeritud toime kaudu granuleerimisprotsessis, PVC vaigu osakesed on täielikult sulanud ja plastifitseeritud, ja lisandid on ühtlaselt hajutatud, mis väldib ebapiisava plastifitseerimise probleeme, komponentide ebaühtlane jaotus, ja sisemised vead puhta vaigu otsesel vormimisel, parandades seega materjali töötlemisvõimet.
Teiseks, see lihtsustab järgnevat töötlemisprotsessi. PVC graanulitel on pärast modifitseerimist ja granuleerimist ühtlane osakeste suurus, hea voolavus, ja stabiilne jõudlus. They can be directly used in extrusion, survevalu, kalandreerimine, blow molding and other molding processes without additional mixing or preprocessing, which reduces the production process, improves production efficiency, and reduces the labor intensity of operators.
Kolmandaks, it ensures the stability of product quality. The performance of modified PVC granules is relatively stable, which can avoid the fluctuation of product performance caused by uneven mixing of additives in direct molding, thus ensuring the consistency of product quality and reducing the product defect rate.
Neljandaks, it expands the application scope of PVC. Through targeted modification (such as adding different modifiers, plastifikaatorid, ja täiteaineid), PVC compounds with different properties can be prepared, which can meet the requirements of different application fields. Näiteks, Kõrge jäikuse ja löögikindlusega jäiku PVC-graanuleid saab kasutada plasttorude ja -profiilide tootmisel; voolikute valmistamisel saab kasutada hea painduvuse ja pehmusega painduvaid PVC-graanuleid, kaablid, ja pakkekiled; leegiaeglustavaid PVC-graanuleid saab kasutada elektri- ja elektroonikatoodete tootmisel.
Tuleb rõhutada, et erinõuetega PVC-toodete puhul (nagu vastupidavus kõrgele temperatuurile, korrosioonikindlus, leegiaeglustus, and transparency) ja PVC modifitseeritud valemid, viime läbi alati kohandatud arendust vastavalt klientide konkreetsetele vajadustele. Meie tehniline meeskond suhtleb klientidega põhjalikult, et mõista nende toote kasutamise stsenaariume, jõudlusnõuded, ja tootmiskulud, ja seejärel kavandage kõige sobivam modifitseeritud valem ja segamisprotsess, et toodetud PVC ühendid vastaksid täielikult kliendi ootustele.
2. Ekstrusiooniseadmed PVC segude segamiseks ja granuleerimiseks
Ekstruuderid on PVC segu segamise põhivarustus, granuleerimine, ja vormimise töötlemine. Need mängivad sulandite plastifitseerimisel üliolulist rolli, nihkega segamine, ja PVC-segude ekstrusioonvormimine. Ekstruuderite tööpõhimõte on kasutada välist jõuülekannet kruvi pööramiseks, ja kasutada tahke aine transportimiseks väliste kütteelementide soojusülekannet ja kruvi pöörlemisel tekkivat nihkesoojust, tihendamine, sulamine, nihkega segamine, ja PVC materjalide ekstrusioon. Olulise seadmena plasti vormimise töötlemisel, extruders are widely used in the granulation of PVC compounds and the molding of various PVC products, and occupy an irreplaceable position in the PVC processing industry.
According to the structure and performance of extruders, we have developed two series of extruders suitable for PVC compound mixing and granulation, namely the ZTE MODEL series and the HTE series.

This series of extruders combines high performance and high cost performance, adopts advanced structural design and core technology, and can effectively improve production capacity, reduce energy consumption, and ensure the high quality of PVC compounds. It is especially suitable for the mixing and granulation of high-grade modified PVC compounds (such as high-impact PVC, flame-retardant PVC, transparent PVC) and PVC products with strict performance requirements.
Konstruktsiooniprojekti osas, the HTE series extruder adopts a twin-screw structure, which has obvious advantages compared with the single-screw extruder in terms of shear mixing, plasticization efficiency, and production capacity. The twin-screw can generate strong shear force and mixing effect during rotation, which can make the PVC mixture and additives more uniformly mixed, and the plasticization degree is higher, thus improving the performance of the PVC compound. According to the shape of the screw, the twin-screw extruder can be divided into conical twin-screw extruder and parallel twin-screw extruder. Nende hulgas, the conical twin-screw extruder is an ideal choice for rigid PVC compound mixing and granulation.
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. See disain võib PVC segu transportimise käigus järk-järgult kokku suruda, ja nihkejõud suureneb järk-järgult, mis soodustab jäiga PVC vaigu sulamist ja plastifitseerimist (millel on kõrge viskoossus ja mis nõuab plastifitseerimiseks tugevat nihkejõudu). Samal ajal, koonilisel kahe kruviga ekstruuderil on hea isepuhastuv jõudlus, mis võib vältida materjali kogunemist kruvisse ja silindrisse, vähendada materjali raiskamist, ja tagada tootmisprotsessi stabiilsus.
Materjali valiku osas, HTE seeria ekstruuderi kruvi ja silin on valmistatud kvaliteetsest kulumis- ja korrosioonikindlast legeerterasest,Pärast spetsiaalset pinnatöötlust (nagu nitriiditöötlus), mis parandab veelgi kruvi ja silindri kõvadust ja kulumiskindlust, and can adapt to the mixing and granulation of PVC compounds containing fillers (nagu kaltsiumkarbonaat) and corrosive additives, prolonging the service life of the equipment.
