Ifilimu ye-Polypropylene cast (CPP) isetshenziswa kabanzi.I-CPP ifilimu yabalingisi enganwetshiwe, engaqondile ekhiqizwe i-melt casting quenching.Uma iqhathaniswa nefilimu eshaywayo, ibonakala ngesivinini sokukhiqiza esisheshayo, ukuphuma okuphezulu, nokubonakala okuhle kwefilimu, ukucwebezela nokufana kokuqina.Ngesikhathi esifanayo, ngenxa yokuthi ifilimu ye-extrusion eyisicaba, izinqubo ezilandelayo ezifana nokunyathelisa kanye ne-lamination zilula kakhulu, ngakho-ke isetshenziswa kabanzi ekufakweni kwezindwangu, izimbali, ukudla, kanye nezidingo zansuku zonke.
Kunezindlela ezimbili zokukhiqiza i-CPP: ukusakaza kwesendlalelo esisodwa kanye nokusakaza okuhlangene kwezendlalelo eziningi.Ifilimu yongqimba olulodwa ngokuyinhloko idinga ukuthi izinto ezibonakalayo zibe nokusebenza okuhle kokuvala ukushisa okuphansi kwezinga lokushisa kanye nokuguquguquka.Ifilimu ye-multi-layer co-extrusion cast ingahlukaniswa ngokwezigaba ezintathu: ungqimba oluvala ukushisa, ungqimba olusekelayo kanye nongqimba lwe-corona.Ukukhethwa kwezinto ezibonakalayo kubanzi kunefilimu yongqimba olulodwa.Izinto ezihlangabezana nezidingo zesendlalelo ngasinye zingakhethwa ngazodwana ukuze zinikeze ifilimu izici ezihlukene, umsebenzi nenjongo.Phakathi kwazo, ungqimba oluvala ukushisa ludinga ukuvalwa ngokushisa, okudinga ukuthi impahla ibe nephuzu elincibilikayo eliphansi, i-hot-melt enhle, izinga lokushisa elibanzi lokuvalwa kokushisa, nokubeka uphawu kalula: isendlalelo sokusekela sisekela ifilimu futhi sandise ukukhanya. ukuqina kwefilimu.Ungqimba lwe-corona ludinga ukuphrinta noma lwenziwe insimbi, okudinga ukushuba okumaphakathi kwendawo, futhi ukungezwa kwezithasiselo kufanele kukhawulwe ngokuqinile.
Ifilimu yabalingisi ye-CPP inokusebenza okuhle kakhulu kokuvalwa kokushisa nokubonakala okuhle kakhulu, futhi ingenye yama-substrates ayinhlanganisela yokupakisha.Isetshenziselwa ukukhiqiza amafilimu okupheka okushisa okuphezulu, amafilimu e-vacuum aluminized, njll. Imakethe inethemba elikhulu.
