Ifilimu yePolyethylene (PE) yimathiriyeli encinci, eguquguqukayo eyenziwe kwi-polyethylene polymer esetyenziswa ngokubanzi ukupakisha, ukhuseleko, kunye nezinye izicelo.Inkqubo yokwenziwa kwefilimu ye-polyethylene inokwahlulwa ngokubanzi ngokwezigaba ezininzi:
- Ukuveliswa kwe-resin: Inyathelo lokuqala kwinkqubo yokwenziwa kukuvelisa izinto eziluhlaza, eziluhlobo lwe-polyethylene resin.Oku kwenziwa ngepolymerization, inkqubo yeekhemikhali eyenza amatyathanga amade eemolekyuli zepolymer ukusuka kwiimonomers ezifana ne-ethylene.Emva koko intlaka iye ifakwe kwipellet, yomiswe, ize igcinwe ukuze iqhubeke nokusebenza.
- I-Extrusion: Inqanaba elilandelayo kukuguqula i-resin ibe yifilimu.Oku kwenziwa ngokugqithisa intlaka kwi-extruder, umatshini onyibilikisa intlaka uze uyinyanzele kwingxuma encinane ebizwa ngokuba yi-die.I-resin enyibilikisiweyo ipholisa kwaye iqina njengoko ikhutshwe, yenze iphepha eliqhubekayo lefilimu.
- Ukupholisa kunye nokujika: Emva kokuba ifilimu ikhutshiwe, ipholiswe phantsi kwiqondo lokushisa kunye nenxeba kumqulu.Ifilimu inokwandiswa kwaye iqondiswe ngexesha le nkqubo, ephucula iimpawu zayo zemishini kwaye yenza ukuba ibe yinto efanayo.
- Ikhalenda: Ifilim inokuqhubekekiswa ngakumbi ngenkqubo ebizwa ngokuba yi-calendering, apho igqithiswa kwiseti yeerola ezifudunyeziweyo ukwenza umphezulu ogudileyo nomenyezelayo.
- I-Lamination: Ifilimu inokudibaniswa kunye nezinye izinto zokwenza isakhiwo se-laminated.Oku kudla ngokwenziwa ngokusebenzisa umaleko wokuncamathelisa phakathi kweengqimba ezimbini okanye ngaphezulu zefilimu, ezibonelela ngeempawu zomqobo eziphuculweyo kunye nokuphucula ukusebenza kwemveliso yokugqibela.
- Ukuprintwa kunye nokusika: Imveliso yokugqibela yefilimu inokuprintwa kunye neepateni ezifunwayo okanye imizobo, kwaye emva koko isikwe kubungakanani obufunwayo kunye nokumila kwezicelo ezithile.
Ezi zigaba zinokuhluka ngokuxhomekeka kwiipropati ezifunwayo kunye nezicelo zokugqibela zokusetyenziswa kwefilimu ye-polyethylene, kodwa inkqubo eyisiseko ihlala ifana.
