Kunzima ukuphikisa ukuthi ukunambitheka kwezitsha kuncike ezimweni zokugcina zezingxenye zayo. Ngeshwa, imikhiqizo eminingi inempilo emfushane yethelefu. Kodwa amanye amadivayisi asiza ukwandisa. Bangakwazi ukufaka ifilimu ye-PVC yokudla.
Iyini ukusetshenziswa kwefilimu ye-PVC?
PVC, noma welula ifilimu, iphakanyisiwe, ngokuvamile ifomula, eyenziwe nge-polyvinyl chloride, impahla ye-polymer enezinto ezikhethekile. Okokuqala, i-film elula yokudla ihamba emoyeni futhi ikhiqiza i-carbon dioxide. Ngenxa yalekhono, imikhiqizo ehlanganiswe kuyo ibonakala sengathi "iphefumula", kodwa umoya awuwutholi ngaphakathi kwephakheji. Ngenxa yalokhu ngaphansi kwe-PVC yokudambisa amafilimu awubonakali amaconsi we-condensate. Ngenxa yalokho, impilo yesheluli yemikhiqizo yanda kakhulu. Ukupakishwa kwefilimu elula kungenza ngisho nemikhiqizo esanda kusetshenzwa ukushisa. Okubalulekile kumkhakha onjalo wemikhiqizo, njengokudla nesinkwa.
Ngaphezu kwalokho, ifilimu ye-PVC iphephile ngokuphelele, ayishiyi noma yiziphi izinto ezilimazayo emikhiqizo. Ngokuyinhloko, ifilimu ye-PVC isetshenziselwa imikhiqizo ehlukahlukene yokudla - inhlanzi, inyama, isoso, imifino, ushizi, amasobhoji, isinkwa. Ububanzi befilimu yokudla bukhulu kakhulu: cishe cishe wonke amaketanga nezitolo. Yisebenzise kanye nasendlini yabendlukazi abasebenza kahle.
Izinhlobo zokudla ifilimu ye-PVC
Ukuhlukaniswa okuyinhloko ekukhiqizeni ifilimu ye-PVC yokudla yi-thickness. Ngakho-ke, isibonelo, ukufakelwa kwezithelo nezimpande, kusetshenziselwa imikhiqizo ye-microns ayi-9. Ifilimu engu-10 μm ifanele isinkwa ne-pasta. Imikhiqizo yezinyama nezinhlanzi zidinga ifilimu enamandla kakhulu - amamitha ayi-10-14.
Inketho evame kakhulu - ifilimu ebonakalayo, lapho ungabona khona isimo semikhiqizo egcinwe. Ngesinye isikhathi abathengisi bahlela ifilimu ye-PVC ngomthunzi, isibonelo, ukuphuzi ukunikeza isinkwa ukubukeka okukhangayo, okuluhlaza okwenziwe imifino.
