Cov thawv yas yog pob tshab folding thawv, lub tog raj kheej, sab saum toj thiab hauv qab npog lub thawv, hnab tes, dai phaib thiab lwm yam khoom siv yas ua los ntawm PVC / PET / PP / PS cov ntaub ntawv, uas tuaj yeem ua tiav cov teebmeem luam ntawv xws li UV offset luam ntawv, tshuaj ntsuam luam ntawv, kub. stamping / nyiaj, sanding, thiab lwm yam.
Cov thawv yas muaj cov yam ntxwv ntawm cov neeg siv kev paub ntau ntxiv, ntim ruaj khov thiab ruaj khov, tsis muaj dej tsis zoo, tiv thaiv dej tsis zoo, muaj zog toughness, muaj zog kev nyab xeeb kev thauj mus los, thiab txhim kho cov khoom qib.
Yas feem ntau yog ua los ntawm hluavtaws lossis ntuj polymer resins. Tom qab ntxiv ntau yam additives, nws muaj ductility ntawm ib tug tej yam kub thiab siab, thiab yuav kho tau nyob rau hauv nws xav tau zoo tom qab txias. Cov txheej txheem ntawm plasticizing ntuj los yog hluavtaws polymer resin molecules uas twb nyob rau hauv lub xeev molten thiab muaj tusyees faib auxiliary molecules nyob ib ncig ntawm lawv yog hu ua plasticization. Cov txheej txheem no yog hu ua plasticization thaum cov nyiaj hnyav tau mus txog, thiab nws suav tias tsis tau plasticized. Cov ntim yas yog ib qho ntawm plaub yam khoom tseem ceeb hauv kev lag luam ntim khoom: ntawv thiab duab los qhia rau 30%, yas nyiaj rau 25%, hlau nyiaj rau 25%, thiab iav nyiaj rau 15%.
