Enqubweni yokucubungula nokusetshenziswa kwamafilimu epulasitiki, ukuthuthukisa impahla yeminye imikhiqizo ye-resin noma yefilimu ayihlangabezani nezidingo zobuchwepheshe obudingekayo bokucubungula, kuyadingeka ukwengeza izithasiselo zepulasitiki ezingashintsha izici zazo zomzimba ukuze kuguqulwe ukusebenza kwe umkhiqizo. Njengenye yezithasiselo ezidingekayo zefilimu eshaywayo, ngezansi kunemininingwane yokwethulwa kwe-ejenti yepulasitiki. Kunama-agent anti-blocking amathathu asetshenziswa ngokuvamile ashelelayo: i-oleic amide, i-erucamide, i-silicon dioxide; Ngaphezu kwezithasiselo, kukhona ama-masterbatches asebenzayo afana nama-masterbatches avulekile nama-masterbatches abushelelezi.
1.I-ejenti eshelelayo
Ukwengeza isithako esibushelelezi kwifilimu njengokwengeza ungqimba lwamanzi phakathi kwezingcezu ezimbili zengilazi, okwenza ifilimu yepulasitiki ibe lula ukuslayida izendlalelo ezimbili kodwa kube nzima ukuzihlukanisa.
2.I-ejenti yokuvula umlomo
Ukwengeza i-opener noma i-masterbatch efilimini njengokusebenzisa i-sandpaper ukwenza ama-rough ebusweni phakathi kwezingcezu ezimbili zengilazi, ukuze kube lula ukuhlukanisa izingqimba ezimbili zefilimu, kodwa kunzima ukushelela.
3.Vula i-masterbatch
Ukwakhiwa kwe-silica (inorganic)
4.I-masterbatch ebushelelezi
Izithako: ama-amide (organic). Engeza i-amide ne-anti-blocking ejenti ku-masterbatch ukuze wenze okuqukethwe okungu-20~30%.
5.Ukukhethwa kwe-ejenti yokuvula
Ku-masterbatch ebushelelezi evulekile, ukukhetha kwe-amide ne-silica kubaluleke kakhulu. Izinga le-amide alilingani, okubangela ithonya le-masterbatch kulwelwesi ngezikhathi ezithile, njengokunambitha okukhulu, amabala amnyama njll., konke okubangelwa ukungcola okudlulele kanye nokuqukethwe okungcolile kwamafutha ezilwane. Enqubweni yokukhetha, kufanele kunqunywe ngokuhambisana nokuhlolwa kokusebenza nokusetshenziswa kwe-amide. Ukukhethwa kwe-silica kubaluleke kakhulu, futhi kufanele kucatshangelwe ezicini eziningi ezifana nobukhulu bezinhlayiyana, indawo ethile yendawo, okuqukethwe kwamanzi, ukwelashwa kwendawo, njll, okunomthelela obalulekile ekukhiqizeni i-masterbatch kanye nenqubo yokukhululwa kwefilimu.
