1. Ifilimu yebhamuza ayizinzanga
I-1) Ukushisa kwe-extrusion kuphantsi kakhulu kwaye inani lokukhutshwa lincinci;
Isisombululo: lungisa ubushushu be-extrusion;
I-2) Yaphazamiseka kwaye yachatshazelwa ngumoya oqinileyo wangaphandle.
Isisombululo: ukuthintela kunye nokunciphisa ukuphazamiseka kokuhamba komoya kwangaphandle.
3) Umthamo womoya wendandatho yokupholisa umoya awuzinzile, kwaye ukupholisa ifilimu ye-bubble ayifani;
Isisombululo: Qwalasela umsesane womoya wokupholisa ukuqinisekisa ukuba kukho umoya ofanayo;
I-4) Ukushisa kwe-Extrusion kuphezulu kakhulu, i-fluidity ye-resin edibeneyo inkulu kakhulu, i-viscosity incinci kakhulu, kulula ukuvelisa ukuguquguquka;
Isisombululo: Lungisa ubushushu be-extrusion;
2. Ukutywinwa kobushushu befilimu kubi
I-1) Ukuba indawo yombethe iphantsi kakhulu, iimolekyuli zepolymer ziya kuqhelaniswa, ukwenzela ukuba ukusebenza kwefilimu kusondele kwifilimu ejoliswe kuyo, okubangelwa ukunciphisa ukusebenza kokutywinwa kobushushu;
Isisombululo: Lungisa ubungakanani bomthamo womoya kwindandatho, yenza ukuba umbethe unyuke phezulu, kangangoko kunokwenzeka phantsi kwendawo yokunyibilika yokuvuthela kweplastiki kunye ne-traction, ukuze kuncitshiswe i-molecular stretching orientation ebangelwa ukuvuthela kunye ne-traction;
Ukuba umlinganiselo wokuvuthela kunye ne-traction ratio ayifanelekanga (inkulu kakhulu), ifilimu iya kuba ne-tensile orientation, eya kuchaphazela ukusebenza kokutywinwa kwe-thermal yefilimu.
Isisombululo: umlinganiselo wokuvuthela kunye nomlinganiselo wokutsaleka kufuneka ube mncinci ngokufanelekileyo, ukuba umlinganiselo wokuvuthela mkhulu kakhulu, kwaye isantya sokutsaleka sikhawuleza kakhulu, i-horizontal and longitudinal tensile yefilimu igqithise, ngoko iya kwenza ukuba ukusebenza kwefilimu kuthande ukuba kumacala omabini. ukuqina, ukutywinwa kobushushu befilimu kuya kuba kubi.
3. Umphezulu wefilimu unzima kwaye awulingani
I-1) Iqondo lokushisa le-extrusion liphantsi kakhulu, iplastiki ye-resin imbi;
Isisombululo: Lungisa i-extrusion setting yeqondo lobushushu, kwaye ngokufanelekileyo wandise ubushushu be-extrusion, ukuqinisekisa ukuba i-resin yenziwe ngeplastiki kakuhle.
2) Isantya se-extrusion sikhawuleza kakhulu.
Isisombululo: Nciphisa isantya se-extrusion ngokufanelekileyo
