PVC utomoni wa filimu,
PVC utomoni kwa filimu olimba, pvc utomoni kwa zofewa PVC filimu,

Kupanga filimu ya PVC

Pali makamaka njira ziwiri zopangira filimu ya pvc: extrusion calendering ndi casting.Extrusion calendering ndiyo njira yambiri.

Filimu ya PVC ikhoza kugawidwa m'magulu awiri akuluakulu: ofewa komanso okhwima.Kufuna kwa msika kwa filimu yolimba ya PVC kumafika pafupifupi magawo awiri mwa atatu.

Pepala lofewa la PVC nthawi zambiri limagwiritsidwa ntchito popanga nsalu zapa tebulo, mphasa zosaterera, ndi zikwama.Chifukwa pepala lofewa la PVC kapena filimu lili ndi zofewa, ndizosavuta kukhala zolimba komanso zovuta kusunga.Izi zimachepetsa kuchuluka kwa ntchito yake.

PVC yolimba ilibe zofewa.Ndilosinthasintha, losavuta kupanga, losavuta kukhala lolimba, lopanda poizoni komanso lopanda kuipitsa.Ili ndi nthawi yayitali yosungira, kukana kutentha kwakukulu, kosavuta kusungunuka.Ndi yosindikiza, ndipo imakhala ndi inki yabwino.Ndiwofunika kwambiri komanso ntchito zazikulu.Zomangamanga ndi zamagetsi zimagwiritsa ntchito 60% ya filimu ndi mapepala apulasitiki a PVC.Makampani ambiri onyamula katundu amadyanso zinthu zambiri za PVC.Palinso ntchito zingapo, monga zopindika bokosi zolembera, kudula kwa laser, ma board ogawa ndi zina zotero.
