Enkambisweni yokucubungula nokusetshenziswa kwamafilimu epulasitiki, ukuze kuthuthukiswe ifa leminye imikhiqizo ye-resin noma ifilimu engahlangabezani nezidingo zobuchwepheshe bayo bokucubungula obudingekayo, kuyadingeka ukwengeza izithasiselo zepulasitiki ezingashintsha izici zazo zomzimba ukuze kushintshwe ukusebenza komkhiqizo. Njengenye yezithasiselo ezidingekayo zefilimu ebhujisiwe, ngezansi kwethulwa okuningiliziwe kwe-ejenti yepulasitiki. Kunezinhlobo ezintathu ezivame ukusetshenziswa njenge-open slippery agent anti-blocking agent: i-oleic amide, i-erucamide, i-silicon dioxide; Ngaphezu kwezithasiselo, kunezi-masterbatches ezisebenzayo njenge-open masterbatches kanye ne-smooth masterbatches.
1. I-ejenti eshelelayo
Ukwengeza isithako esibushelelezi efilimini njengokufaka ungqimba lwamanzi phakathi kwezingcezu ezimbili zengilazi, okwenza ifilimu yepulasitiki kube lula ukuyishelela izingqimba ezimbili kodwa kube nzima ukuzihlukanisa.
2. I-ejenti yokuvula umlomo
Ukwengeza i-opener noma i-masterbatch efilimini njengokusebenzisa i-sandpaper ukugoqa indawo ephakathi kwezingcezu ezimbili zengilazi, ukuze kube lula ukuhlukanisa izingqimba ezimbili zefilimu, kodwa kunzima ukushelela.
3. Vula i-masterbatch
Ukwakheka kuyi-silica (inorganic)
4. I-masterbatch ebushelelezi
Izithako: ama-amide (angokwemvelo). Faka i-amide kanye ne-anti-blocking agent ku-masterbatch ukuze wenze okuqukethwe okungu-20 ~ 30%.
5. Ukukhetha i-ejenti yokuvula
Ku-masterbatch evulekile ebushelelezi, ukukhetha i-amide ne-silica kubaluleke kakhulu. Ikhwalithi ye-amide ayilingani, okuholela ekuthonyeni kwe-masterbatch kulwelwesi ngezikhathi ezithile, njengokunambitheka okukhulu, amabala amnyama njll., konke okubangelwa ukungcola okweqile kanye nokuqukethwe okungcolile kwamafutha ezilwane. Enqubweni yokukhetha, kufanele kunqunywe ngokuya ngokuhlolwa kokusebenza kanye nokusetshenziswa kwe-amide. Ukukhethwa kwe-silica kubaluleke kakhulu, futhi kufanele kucatshangelwe ezicini eziningi njengosayizi wezinhlayiya, indawo ethile yobuso, okuqukethwe kwamanzi, ukwelashwa kobuso, njll., okunomthelela obalulekile ekukhiqizweni kwe-masterbatch kanye nenqubo yokukhishwa kwefilimu.
