I-PVC resin yefilimu
I-PVC resin yefilimu,
I-PVC resin yefilimu eqinile, pvc resin for soft PVC ifilimu,
Ukukhiqizwa kwefilimu ye-PVC
Ngokuyinhloko kunezindlela ezimbili zokukhiqiza ifilimu ye-pvc: i-extrusion calendering kanye nokusakaza.I-Extrusion calendering iyindlela eningi kakhulu.
Ifilimu ye-PVC ingahlukaniswa ngamaqembu amabili amakhulu: athambile futhi aqinile.Isidingo semakethe sefilimu ye-PVC eqinile sifinyelela cishe izingxenye ezimbili kwezintathu.
Ishidi le-PVC elithambile ngokuvamile lisetshenziselwa izindwangu zetafula, omata abangasheleli, nezikhwama.Ngenxa yokuthi ishidi le-PVC elithambile noma ifilimu liqukethe izinto ezithambisayo, kulula ukuba brittle futhi kube nzima ukuzigcina.Lokhu kukhawulela ububanzi bohlelo lwayo lokusebenza.
I-PVC eqinile ayinazo izithambisa.Iyavumelana nezimo, kulula ukuyakheka, akulula ukuba brittle, ayinabuthi futhi ayinakho ukungcola.Inesikhathi eside sokugcina, ukumelana nokushisa okuphezulu, akulula ukuncibilika.Iyaphrinta, futhi inomphumela omuhle we-inking.Inenani elikhulu kanye nezicelo ezinkulu.Isakhiwo kanye nezinto zikagesi zisebenzisa u-60% wefilimu namashidi epulasitiki ye-PVC.Izimboni eziningi zokupakisha nazo zisebenzisa izinto eziningi ze-PVC.Kukhona futhi izinhlelo zokusebenza ezimbalwa, njengebhokisi lokubhalela eligoqayo, ukusika kwe-laser, namabhodi okuhlukanisa nokunye.
