Isingeniso Se-ejenti yokuvula i-Silicon Dioxide

Amakhemikhali omkhiqizo azinzile, angavimbela ngokuphumelelayo ukunamathela kwefilimu, ukunciphisa i-coefficient yokungqubuzana, ukwenza ukugoqa kwefilimu kube bushelelezi, ukunciphisa imibimbi, kwenze kube lula ukwenza ukusika kwesibili noma ukuqaqa ifilimu, futhi kube lula ukufuduka komfaniswano kwamafutha noma ama-anti-static agents.
Ngokuphathelene nokusebenza, umsebenzi oyinhloko we-silica ye-ejenti yokuvula ukuvimbela ukunamathela kwezinto. Esikhathini sokukhiqiza ifilimu yepulasitiki, isibonelo, ukwengeza i-masterbatch yokuvula eyenziwe nge-silica kumafilimu e-polyethylene kanye ne-polypropylene kungenza ama-protrusions amancane ebusweni befilimu, ukunciphisa indawo yokuxhumana phakathi kwamafilimu, futhi ngaleyo ndlela kunciphise ukungqubuzana phakathi kwamafilimu, okwenza ifilimu ibe bushelelezi ukuze ivuleke ngaphandle kokunamathela.
Umkhiqizo wethu unokuhlakazeka okuhle futhi awukhiqizi amaphuzu amaningi ekristalu. Usayizi wezinhlayiyana umaphakathi futhi usatshalaliswa ngokulinganayo, futhi akulula ukuvimba isikrini sokuhlunga. Inkomba ye-refractive ifana neye-resin, enciphisa umthelela ekukhanyeni kwefilimu, inciphisa ukugqokwa kwemishini, futhi inombala wemvelo nofanayo. Ayiklwebhi ubuso befilimu futhi ayithinti umphumela wokupakisha.
Ngezinhlelo zokusebenza ezithile, ama-synthetic silica open agents anosayizi wezinhlayiyana we-3-8 μ m ngokuvamile asetshenziswa kwifomu lempushana. Kumele ziqale zixutshwe nenani elithile le-resin ye-carriers ngokusebenzisa i-twin-screw extruder ukuze zincibilike futhi zenziwe ngepulasitiki zibe yi-5-10% high concentration masterbatch. Ngemva kwalokho, zingangezwa kumkhiqizo wefilimu ngesilinganiso esithile futhi zixutshwe nezinye izithasiselo ukuze zenze i-masterbatch eyinhlanganisela. Kubakhiqizi beresin, inani elincane lika-0.1% kuya ku-1% lifakwa enqubweni yokukhiqiza i-polymer ukuze kwenziwe izinto ezikhethekile ezizosetshenziswa abakhiqizi bamafilimu angezansi. Ifanele izinhlobo ezivamile embonini, futhi inani le-ejenti yokuvula eyengezwe liyahlukahluka kuye ngezinhlobo ezahlukene zamafilimu.
Izindawo zokufaka isicelo: Ifilimu ye-polypropylene e-Biaxially oriented (BOPP), ifilimu ye-polypropylene eyi-cast (CPP), ifilimu ye-polyolefin evuthwe (PP, PE), ifilimu ye-polyester egxile ku-biaxially (BOPET), ifilimu enayiloni eqondiswe ku-biaxially (BOPA)
