1. Ifilimu yebhamuza ayizinzile
1) Izinga lokushisa le-extrusion liphansi kakhulu futhi inani lokukhishwa lincane;
Isixazululo: lungisa izinga lokushisa le-extrusion;
I-2) Yaphazanyiswa futhi yathonywa ukugeleza komoya okuqinile kwangaphandle.
Isixazululo: vimbela futhi unciphise ukuphazamiseka kokugeleza komoya kwangaphandle.
3) Umthamo womoya wendandatho yokupholisa umoya awuzinzile, futhi ukupholisa kwefilimu ye-bubble akufani;
Isixazululo: Hlola iringi yomoya opholisayo ukuze uqinisekise ukutholakala komoya okufanayo nxazonke;
4) Ukushisa kwe-Extrusion kuphezulu kakhulu, i-fluidity ye-resin ehlanganisiwe inkulu kakhulu, i-viscosity incane kakhulu, kulula ukukhiqiza ukushintshashintsha;
Isixazululo: Lungisa izinga lokushisa le-extrusion;
2. Ukuvalwa kokushisa kwefilimu kubi
I-1) Uma iphuzu lamazolo liphansi kakhulu, ama-molecule e-polymer azoqondiswa, ukuze ukusebenza kwefilimu kusondele kulokho kwefilimu eqondiswe, okuholela ekunciphiseni kokusebenza kokuvala ukushisa;
Isixazululo: Lungisa usayizi wevolumu yomoya eringini, wenze amazolo akhuphuke, ngangokunokwenzeka ngaphansi kwendawo yokuncibilika yokuvunguza nokudonsa kwepulasitiki, ukuze unciphise ukuma kwamangqamuzana okunwebeka okubangelwa ukufutha nokudonsa;
Uma isilinganiso se-blowout ne-traction ratio singafanelekile (sikhulu kakhulu), ifilimu izoba nomumo oqinile, okuzothinta ukusebenza kokuvala okushisayo kwefilimu.
Isixazululo: isilinganiso sokuphefumula kanye nesilinganiso sokudonsa kufanele sibe sincane ngokufanelekile, uma isilinganiso sokushaywa sisikhulu kakhulu, futhi isivinini sokudonsa sishesha kakhulu, ukuqina kwefilimu okuvundlile nelongitudinal kweqile, khona-ke kuzokwenza ukusebenza kwefilimu kuthambekele ekuqondeni kabili. ukushuba, ukuvala ukushisa kwefilimu kuzoba kubi kakhulu.
3. Ingaphezulu lefilimu lukhuni futhi alilingani
1) Ukushisa kwe-extrusion kuphansi kakhulu, i-plasticization ye-resin imbi;
Isixazululo: Lungisa ukulungiselelwa kwezinga lokushisa le-extrusion, futhi ukhuphule izinga lokushisa ngokufanelekile, ukuze uqinisekise ukuthi inhlaka yenziwe ngepulasitiki kahle.
2) Ijubane le-extrusion lishesha kakhulu.
Isixazululo: Yehlisa isivinini se-extrusion ngendlela efanele
