1).Isivinini sokukhiqiza solayini wokukhiqiza ifilimu ye-extrusion siphezulu kunaleso sendlela yefilimu ephephethwa umoya, engaba phezulu njengo-300m/min, kuyilapho indlela yefilimu evutheliwe ngokuvamile iba ngu-30-60m/min kuphela ngenxa yomkhawulo wokupholisa. isivinini sefilimu ye-bubble.Izinga lokushisa eliphakathi nendawo lokupholisa lingaba ngu-0-5℃, futhi linamathiselwe ngokuqondile ku-roller, futhi umphumela wokupholisa muhle.
2).Ukungafihli kwefilimu yabalingisi be-extrusion kungcono kunokwendlela yefilimu eshaywayo.Kungakhathaliseki ukuthi i-PE noma i-pp, ingakhiqiza ifilimu enokucaca okuhle ngendlela yokusakaza ye-extrusion.Kodwa-ke, uma indlela yokufutha kwefilimu ipholile emoyeni, i-p ayikwazi ukuba nokukhanyela okuhle.Ukuze uthole ukukhanya okuhle, indlela yokupholisa amanzi kufanele isetshenziswe.
3).Ukufana kogqinsi kwendlela yokukhipha i-extrusion kungcono kunaleyo yendlela yefilimu ephephethiwe.
4).Izakhiwo ze-longitudinal kanye ne-transverse zefilimu ye-extrusion cast ziyalingana, kuyilapho izakhiwo ze-longitudinal ne-transverse zefilimu eshaywayo zihlukile ngenxa yomehluko wejubane le-traction roller kanye ne-inflation ratio.Ngokuyisisekelo, ifilimu ekhiqizwa indlela yokukhipha i-extrusion idluliselwa isuka komunye umqulu iye komunye ngaphandle kokushuba kokusonta noma ukudonsa, ngakho-ke ifilimu yokukhipha i-extrusion ayinwetshiwe ku-longitudinal noma isiqondiso esiphambene, futhi ukusebenza kuyalingana.
