Enqubweni yokucubungula nokusetshenziswa kwamafilimu epulasitiki, ukuthuthukisa impahla ye-resin ethile noma imikhiqizo yefilimu ayihlangabezani nezidingo zobuchwepheshe obudingekayo bokucubungula, kuyadingeka ukwengeza izithasiselo zepulasitiki ezingashintsha izici zabo zomzimba ukuze uguqule ukusebenza komkhiqizo. 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
Ukwakheka 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.
