I-POLYVINYL CHLORIDE FILM, yenziweI-PVC resinnezinye izilungisi ngenqubo ye-calender noma inqubo yokubumba igalelo.Ubukhulu obujwayelekile bungu-0.08~0.2mm, bukhulu kuno-0.25mm obubizwa ngeshidi le-PVC.I-Plasticizer, i-stabilizer, i-lubricant kanye nokunye ukucubungula okusebenzayo kwe-AIDS kwengezwa ku-PVC resin, futhi ifilimu yenziwa nge-calendering.

Ifilimu ye-PVC ingahlukaniswa izigaba ezimbili, esisodwa i-PVC Film, eyaziwa nangokuthi ifilimu ye-PVC ethambile, enye i-Unplasticized PVC Film, eyaziwa nangokuthi i-hard PVC Film.

Phakathi kwazo, i-PVC eqinile ibalelwa ku-2/3 wemakethe, kanye nama-akhawunti athambile e-PVC angu-1/3.I-PVC ethambile ngokuvamile isetshenziselwa indawo yaphansi, uphahla kanye nesikhumba, kodwa ngenxa yokuthi i-PVC ethambile iqukethe isithambisa (lokhu futhi umehluko phakathi kwe-PVC ethambile ne-PVC eqinile), kulula ukuba yi-brittle, akulula ukuyilondoloza, ngakho ububanzi bayo bokusetshenziswa bulinganiselwe. .I-PVC eqinile ayiqukethe okokuthambisa, ngakho inokuguquguquka okuhle, ukubumba okulula, akulula ukucwenga, okungeyona ubuthi futhi akungcolisi, isikhathi eside sokulondoloza, ngakho-ke inokuthuthukiswa okukhulu kanye nenani lesicelo.Ingqikithi yefilimu ye-PVC iyifilimu ye-vacuum blister, esetshenziselwa ukupakishwa kwendawo yazo zonke izinhlobo zamaphaneli, ngakho-ke yaziwa nangokuthi ifilimu yokuhlobisa, ifilimu yokunamathisela, esetshenziselwa izinto zokwakha, ukupakisha, imithi kanye nezinye izimboni eziningi.Phakathi kwazo, imboni yezinto zokwakha ibamba ingxenye enkulu yama-60%, ilandelwa yimboni yokupakisha, kunezinye izinhlelo zokusebenza ezincane zemboni.

⑴ Ngokusho kwempahla eluhlaza esetshenziselwa ukwenza ifilimu: ifilimu ye-polyethylene, ifilimu ye-polypropylene, ifilimu ye-polyvinyl chloride nefilimu ye-polyester.

(2) Ukuhlukaniswa ngokusetshenziswa kwefilimu: ifilimu yezolimo (lapha ngokusho kokusetshenziswa okuqondile kwefilimu yezolimo, ingahlukaniswa ifilimu yepulasitiki kanye nefilimu ye-greenhouse);Ifilimu yokupakisha (Ifilimu yokupakisha ngokusho kokusetshenziswa kwayo okuqondile, futhi ingahlukaniswa ifilimu yokupakisha ukudla kanye nefilimu yokupakisha yemikhiqizo yezimboni ehlukahlukene, njll.) kanye nemvelo ekhethekile, ngokusetshenziswa okukhethekile kwefilimu ephefumulayo, ifilimu encibilikayo emanzini kanye nezakhiwo ze-piezoelectric zefilimu. .

(3) Ngokwesigaba sendlela yokubumba ifilimu: i-extrusion plasticization, bese ishaya ifilimu yokubumba, ebizwa ngokuthi ifilimu yokubumba ifilimu;Ngemuva kwe-extrusion plasticization, bese kuthi izinto ezincibilikisiwe zigeleze ziphuma emlonyeni wesikhunta ozenza ifilimu, ebizwa ngokuthi ifilimu yokugeleza;Emshinini we-calendering ngama-rolls amaningana agayiwe izinto ezenziwe ngefilimu, ezibizwa ngefilimu ye-calendering.

Ukusetshenziswa kwefilimu ye-PVC
