Ifilimu yepulasitikikuyinto encane eqhubekayo ye-polymeric material.Izinto zepulasitiki eziwugqinsi zivame ukubizwa ngokuthi “ishidi”.Lezi zingqimba zepulasitiki ezincanyana zisetshenziselwa ukuhlukanisa izindawo noma amavolumu, ukubamba izinto, ukusebenza njengezithiyo, noma njengendawo ephrintekayo.
Amafilimu epulasitiki asetshenziswa ezinhlobonhlobo zezicelo.Lokhu kufaka phakathi: ukupakishwa, izikhwama zepulasitiki, amalebula, ukwakhiwa kwebhilidi, ukulungiswa kwezwe, ukwenziwa kukagesi, ifilimu yezithombe, isitokwe sefilimu samamuvi, itheyiphu yevidiyo, njll.
Izinqubo
Amafilimu epulasitiki ngokuvamile ama-thermoplastics futhi akhiwa ngokuncibilika ukuze enze ifilimu.
I-Cast - I-Plastiki extrusion ingasakaza ifilimu epholile noma icime bese iboshwe kumqulu.
Ifilimu enwetshiwe inganwetshwa, incitshwe, noma iqondiswe ohlangothini olulodwa noma ezimbili.Inqubo eshaywayo noma ye-tubular iphoqa umoya ukuba ube yindandatho ekhishwe ukuze inwebe ifilimu.Amafreyimu amathenda ayisicaba anweba ifilimu ekhishwe ngaphambi kokuhushulwa.
Imiqulu yekhalenda ingasetshenziswa ukwenza ifilimu kusuka kuma-polymer ashisayo
Ukufakwa kwesixazululo kungenye inqubo yokwenza ifilimu.
I-Skiving isetshenziselwa ukuklebhula ifilimu kusuka kumongo oqinile (ngezinye izikhathi kusetshenziselwa ukwenza i-PTFE thread seal tape)
I-Coextrusion ihilela ukukhipha izendlalelo ezimbili noma ngaphezulu zama-polymer ahlukene zibe ifilimu eyodwa
I-Lamination ihlanganisa amafilimu amabili noma ngaphezulu (noma ezinye izinto) zibe sandwich
I-Extrusion coating isetshenziselwa ukwenza ifilimu kwenye ifilimu noma i-substrate
