Ziziphi iimfuno zobushushu kwimveliso yefilimu ekhuselayo ye-PE?

Ifilimu ekhuselayo ye-PE luhlobo olutsha lwemveliso yeplastiki yokupakishwa kwezinto, ekwasetyenziswa ngokubanzi kwipakethe ephakathi yazo zonke iintlobo zeempahla, esetyenziswa kakhulu kurhwebo lokuthumela ngaphandle, ishishini lamaphepha, ihardware, iikhemikhali zeplastiki, izinto zokwakha zokuhombisa, ishishini lokutya, oomatshini bonyango. kunye neminye imimandla.

Maninzi amalungiselelo athile obushushu kwinkqubo yokuveliswa kwefilimu ye-PE, ngoku makhe sidlule kuzo.

Ngokwemisebenzi eyahlukeneyo yobushushu, ukuveliswa kwefilimu ye-PE kunokohlulwa ngokwala manqanaba mabini alandelayo:

1. Ukufudumeza

Kwisiseko sokuba impahla yefilimu ye-PE ayinakwenzeka kumonakalo we-steam, ixesha lokufudumala akufanele libe lide kakhulu, kwaye i-steam kufuneka idluliselwe kwi-cabin yokugcina i-1 ~ 1.5 iiyure.Umzekelo, phantsi kwemeko ebandayo kunye nemanzi ye-96 ~ 100 ℃, ixesha lokulawula ubushushu liyi-8 iiyure entwasahlobo nasekwindla, iiyure ezi-7 ehlotyeni kunye neeyure ezili-10 ebusika.

2. Ukulawula ubushushu

Ulawulo lobushushu linyathelo eliphambili lokuqiniswa, ukuguqulwa kwe-hydrothermal kunye nokuphucula amandla okuqina.Ngokunyuka kwexesha lokulawula ubushushu, i-carbohydrate iqokelela, ukwanda kwamandla okuqina kuba ngokukhawuleza kwaye ngokukhawuleza.Emva kwexesha elithile lokulawula ubushushu, ukonyuka kwamandla okuqina kunciphisa kancinci.Izinto ezikrwada ezahlukeneyo, amanyathelo ahlukeneyo okuvelisa okanye okucubungula, iibhloko ezahlukeneyo ezifakwe umoya, zonke kufuneka zihambelane namaxesha azo okulawula ubushushu.

Oku ngasentla kukubonelela ngokumalunga nobushushu kwinkqubo yokuvelisa ifilimu yokukhusela ye-PE.Ukulawulwa okungqongqo kwimveliso kunye nobushushu bokuvelisa, kuqinisekisa ukuba iifilimu ezikhuselayo ze-PE zinamandla aphezulu, amandla acinezelayo aphezulu, ukuzincama okuhle kunye nomgangatho ophezulu.
