Ifilimu ye-Polyethylene (PE) iyinto encane, eguquguqukayo eyenziwe nge-polyethylene polymer esetshenziselwa kakhulu ukupakisha, ukuvikela, nezinye izinhlelo zokusebenza.Inqubo yokukhiqiza ifilimu ye-polyethylene ingahlukaniswa kabanzi ngezigaba eziningana:
- Ukukhiqizwa kwe-resin: Isinyathelo sokuqala senqubo yokukhiqiza ukukhiqiza impahla eluhlaza, okuwuhlobo lwe-polyethylene resin.Lokhu kwenziwa nge-polymerization, inqubo yamakhemikhali eyenza amaketanga amade ama-molecule e-polymer avela kuma-monomers afana ne-ethylene.Khona-ke i-resin igaywa nge-pellet, yomiswe, futhi igcinwe ukuze iqhubeke nokusebenza.
- I-Extrusion: Isigaba esilandelayo ukuguqula inhlaka ibe ifilimu.Lokhu kwenziwa ngokudlulisela inhlaka emshinini okhipha inhlaka, umshini oncibilikisa inhlaka bese uyiphoqa ngembobo encane ebizwa ngokuthi i-die.I-resin encibilikisiwe iyaphola futhi iqine njengoba ikhishwa, yenze ishidi lefilimu eliqhubekayo.
- Ukupholisa nokusonteka: Ngemva kokuba ifilimu isikhishiwe, ipholiswa ibe ngaphansi kwezinga lokushisa elilingana negumbi bese ilinyelwa emqulwini.Ifilimu inganwetshwa futhi iqondiswe phakathi nale nqubo, ethuthukisa izakhiwo zayo zemishini futhi iyenze ibe yinto efanayo.
- I-Calendering: Ifilimu ingaphinde icutshungulwe ngenqubo ebizwa nge-calendering, lapho idluliswa kusethi yamarola ashisayo ukuze kwakhe indawo ebushelelezi futhi ecwebezelayo.
- I-Lamination: Ifilimu ingahlanganiswa nezinye izinto zokwakha isakhiwo se-laminated.Lokhu kuvame ukwenziwa ngokusebenzisa isendlalelo sokunamathisela phakathi kwezingqimba ezimbili noma ngaphezulu zefilimu, ehlinzeka ngezakhiwo ezithuthukisiwe zokuvimbela futhi ithuthukise ukusebenza komkhiqizo wokugcina.
- Ukuphrinta nokusika: Umkhiqizo wokugcina wefilimu ungaphrintwa ngamaphethini afiswayo noma ihluzo, bese usikwa kusayizi oyifunayo kanye nokuma kwezinhlelo zokusebenza ezithile.
Lezi zigaba zingahluka kuye ngokuthi izakhiwo ezifunwayo kanye nezicelo zokusetshenziswa kokuphela kwefilimu ye-polyethylene, kodwa inqubo eyisisekelo ihlala ifana.
