Kungani izengezo ezishelelayo ne-anti-block zibalulekile ekukhiqizeni amafilimu epulasitiki?

Izindiza kanye ne-anti-block adlitiveszisetshenziswa ekukhiqizeni amafilimu epulasitiki, ikakhulukazi ngezinto zokwakha ezinjenge-polyolefins (isib. polyethylene ne-polypropylene), ukuthuthukisa ukusebenza ngesikhathi sokukhiqiza, ukucubungula kanye nokusetshenziswa. Nakhu ukuthi kungani bebalulekile:
Izithasiselo zeSlip zinciphisa ukungqubuzana phakathi kwezindawo zefilimu noma phakathi kwefilimu nemishini. Lokhu kwenza kube lula kumafilimu ukuhambisa kahle ngemigqa yokukhiqiza, kubavimbele ekunamatheleni imishini, futhi ithuthukise ukuphathwa emisebenzini yokupakisha. Isibonelo, ngaphandle kokusheshisa, ifilimu yepulasitiki lingahudula noma lijamu ngesikhathi sejubane eliphezulu, liphuze izinto phansi noma zibangele amaphutha. Baphinde basize ekusetshenzisweni kwezicelo ezifana nezikhwama noma ukugoqa, lapho ufuna izingqimba ukuslayida kalula lapho uvulwa.
Anti-block adlitives, ngakolunye uhlangothi, sibhekane nenkinga ehlukile: Bamisa izingqimba zefilimu ukuthi zinamathele ndawonye, ​​impikiswano ejwayelekile eyaziwa ngokuthi "ukuvimba." Ukuvinjwa kwenzeka lapho amafilimu ecindezelwa ndawonye - yithi, emgomeni noma isitaki - futhi unamathele ngenxa yokucindezela, ukushisa, noma ukubekezelela kwabo ngokwemvelo. Izithasiselo ze-Anti-block zidala ukungahambi kahle komhlaba omncane, ukunciphisa ukuxhumana phakathi kwezendlalelo nokwenza kube lula ukunqanda ama-rolls noma amashidi ahlukile ngaphandle kokudwengula.
Ngokubambisana, lezi zengezo zithuthukisa ukusebenza kahle nekhwalithi. Basheshisa ukukhiqizwa ngokunciphisa isikhathi sokuphumula besuka ezindabeni ezinamathela noma zokuphambana, bathuthukise ukusebenza komkhiqizo wokugcina (cabanga ngezikhwama zepulasitiki zokugcina), futhi zilondoloze ukucaciswa noma ezinye izakhiwo ezifunwayo lapho zilinganiselwe kahle. Ngaphandle kwabo, abakhiqizi babezobhekana nezinqubo ezihamba kancane, imfucuza engaphezulu, kanye nomkhiqizo osebenzayo omncane - ubuhlungu bekhanda akekho okufunayo.
