Enqubweni yokukhiqizwa kwe-PVC, ngenxa yemingcele yefomula yokulawula inqubo yokukhiqiza nezinye izici, uhlobo olufanayo lwe-PVC olukhiqizwa izinkampani ezahlukene (uhlobo lwe-SG5 ngokwesibonelo) ekusebenzeni luhlukile Kumabhizinisi okucubungula i-PVC, avame ukufana. isikhathi sokusetshenziswa kwemikhiqizo eminingi, kanye nenkampani ehlukene ekukhiqizeni i-PVC ekuhlukeni kokusebenza (ngisho nokuncane), idinga amabhizinisi acubungula inqubo yokukhiqiza ifomula yokulungisa efanele, i-PVC, noma enye ifomula efanayo yezinkampani ezahlukene ingase ivele ukucubungula inkinga yekhwalithi yokukhiqiza Ngakho-ke, kumabhizinisi okucubungula i-PVC, qonda imingcele yokusebenza ye-PVC ngayinye, ingaklanywa ngokuvumelana nezici zokusebenza zemikhiqizo yayo, ukugwema ukulungisa iphutha okungaboni okubangelwa ukuchithwa kwezinsiza Kumabhizinisi okukhiqiza i-PVC, ukuqonda inkampani. ukukhiqizwa kwe-PVC nezinye izinkampani kumehluko wokusebenza, zingagqamisa amandla azo, zinxephezele ubuthakathaka bazo, zenze umkhiqizo ube nezimo zokuncintisana ezimakethe, umbhali kuphela wasekhaya AB c DE abakhiqizi be-PVC ngokubonakala kwe-viscosity yokuhlolwa kokuncibilika okubonakalayo kokusebenza. Ekuhlolweni, umbhali ngokuphelele ngokuhambisana nesimiso sokufuna iqiniso emaqinisweni, ukuhlolwa okulungile nokunenjongo, ngokusho kwemfundiso eyisisekelo yokucubungula kwe-PVC, ukusebenza kwezinkomba zomkhiqizo kuqhathaniswa.
(1) I-PVC ekhiqizwe i-Factory C ine-viscosity ephezulu kakhulu.Ukuphakama kwe-viscosity, i-PVC resin plasticizing enzima kakhulu, ukucubungula okunzima kakhulu;I-viscosity ephansi kunazo zonke yi-A, B, E factory ekhiqizwa i-PVC, i-viscosity iphansi, i-PVC resin ilula ukwenza ipulasitiki, kulula ukuyicubungula.
(2) Ukuminyana okusobala kwePVC ekhiqizwe ifektri B inkulu kakhulu, futhi leyo ekhiqizwa ifektri E incane kakhulu.Enqubweni yokucutshungulwa kwenhlaka ye-PVC, izinhlayiya zenhlaka ye-PVC ezincane (okungukuthi, ukuminyana okukhulu okubonakalayo), imikhiqizo eyenziwe intekenteke futhi inombolo "yeso lezinhlanzi" incane, kulula ukuyicubungula.
(3) Inani lokumuncwa kwe-plasticizer lalilikhulu ku-PVC elikhiqizwe ifektri C futhi elincane ku-PVC elikhiqizwe ifektri B. Uma likhulu inani lokumuncwa kwe-plasticizer, i-PVC resin enqubweni yokuxuba kulula ukumunca i-plasticizer, i-lubricant nokunye. ukucubungula izithasiselo, izinga lengxube lihle, ukusebenza kwayo kokuncibilika kokucubungula nakho kungcono.
(4) Inombolo “yamehlo ezinhlanzi” akhiqizwa ifektri engu-B iyi-PVC eningi kakhulu."I-Fisheye" iwumgogodla wenqubo ye-polymerization ngenxa yezimo ezingalungile kanye nokwakheka kwenani elincane lesakhiwo samangqamuzana e-polymer PVC, okunzima ukuyifaka ipulasitiki ngesikhathi sokucubungula i-PVC, inomthelela omkhulu kwikhwalithi yomkhiqizo, ngakho-ke okuncane inani elithi "fisheye" lingcono.
(5) Ngokombono wesikhathi sokuzinza kwe-thermal, i-PVC ekhiqizwa ifektri B inesikhathi eside kakhulu sokuzinza kokushisa, kuyilapho i-PVC ekhiqizwa ifektri D inesikhathi esifushane kakhulu sokuzinzisa okushisayo.Ukuzinza okushisayo kwe-resin kuthinta ngokuqondile ukucutshungulwa kwemikhiqizo, ikakhulukazi emikhiqizweni eqinile.Ukuze uvimbele ukubola kwe-PVC enqubweni yokucubungula, ukwandisa isikhathi sokucubungula, kufanele ulungise umthamo we-stabilizer kufomula ngokuvumelana nokuzinza kwayo.
