Amafilimu e-PVC asetshenziswa kabanzi ekufakweni kokudla, ezolimo, nasekufakweni kwezimboni. I-Extrusion kanye ne-calendering yizinqubo ezimbili eziyinhloko zokukhiqiza.
I-Extrusion: Ukusebenza kahle Kuhlangabezana Nenzuzo Yezindleko
Isikhungo sokukhipha sizungeze i-screw extruder. Izinto ezihlangene zonga isikhala futhi kulula ukuzifaka nokuyilungisa. Ngemuva kokuxuba izinto ngokuya ngefomula, zingena ngokushesha ku-extruder. Njengoba isikulufu sizungeza ngesivinini esikhulu, izinto zokwakha zenziwa ipulasitiki ngokushesha ngamandla okugunda kanye nokushisa okunembile. Khona-ke, zidluliselwa ekubunjweni kwefilimu yokuqala ngekhanda lokufa eliklanywe ngokucophelela, futhi ekugcineni zipholiswe futhi zilolongelwe ama-roller okupholisa kanye nendandatho yomoya. Inqubo iyaqhubeka nokusebenza kahle okuphezulu.
Ugqinsi lwefilimu lusukela ku-0.01mm kuye ku-2mm, luhambisana nezidingo ezahlukahlukene. Nakuba incane iyunifomu ngogqinsi kunamafilimu ekhalenda, isebenzela imikhiqizo enezidingo ezinembayo eziphansi. Ukusebenzisa izinto ezigaywe kabusha kunciphisa izindleko. Ngokutshalwa kwezimali kwemishini ephansi kanye nokusetshenziswa kwamandla, inikeza umkhawulo wenzuzo enkulu. Ngakho-ke, amafilimu e-extrusion asetshenziswa kakhulu kwezolimo kanye nokupakishwa kwezimboni, njengamafilimu abamba ukushisa kanye namafilimu e-cargo stretch.
Ikhalenda: Okufanayo nekhwalithi ephezulu
Imishini yendlela ye-calendering yakhiwe ngama-roller okushisa amaningi anembayo ephezulu. Ezivamile ziyi-three-roll, i-four-roll noma i-five-roll calender, futhi ama-roller adinga ukulungiswa ngokucophelela ukuze kuqinisekiswe ukunemba kokusebenza. Izinto ezisetshenziswayo ziqale zixutshwe yi-high-speed kneader, bese zifaka i-mixer yangaphakathi ye-plasticization ejulile, futhi ngemva kokucindezelwa emashidini ngomshini ovulekile, zingena kwi-calender. Ngaphakathi kwekhalenda, amashidi akhishwe ngokunembile futhi anwetshwe ngama-roller amaningi okushisa. Ngokulawula izinga lokushisa nokuhlukaniswa kwama-roller, ukuchezuka kogqinsi kwefilimu kungasimamiswa phakathi kuka-±0.005mm, futhi ukuphakama kwendawo kuphezulu.
Amafilimu e-PVC anekhalenda anogqinsi olufanayo, izakhiwo ezilinganiselayo zemishini, izakhiwo ezinhle kakhulu zokubona, nokucaca okuphezulu. Emaphaketheni okudla, bakhombisa ngokudla futhi baqinisekise ukuphepha. Ezimpahleni zansuku zonke ezisezingeni eliphezulu kanye nokupakishwa kwemikhiqizo ye-elekthronikhi, ikhwalithi yazo ephakeme izenza zibe ukukhetha okuphezulu.
Ekukhiqizeni amafilimu e-PVC, kungakhathaliseki ukuthi inqubo ye-calendering noma inqubo ye-extrusion,I-PVC stabilizersdlala indima ebalulekile.I-TopJoy Chemical'si-liquid barium-zincfuthii-calcium-zinc stabilizersvimbela ukuwohloka kwe-PVC emazingeni okushisa aphezulu, uqinisekise ukuzinza kwezinto, uhlakaze kahle ohlelweni lwe-PVC, futhi uthuthukise ukusebenza kahle kokukhiqiza. Siyakwamukela ukuxhumana nathi nganoma yisiphi isikhathi futhi sibheke phambili ukubambisana okwengeziwe nawe!
