Rigid PVC FIlms yog cov khoom ntim ntau yam siv rau ntau daim ntawv thov ntim.Cov khoom yog ib qho yooj yim mus siv raws li rau lwm cov yas substrates ... nws cov yam ntxwv xws li clarity, formability ntawm qis kub, yooj yim printability ua rau nws ib tug khoom ntawm yooj yim.
Rau kev tsim thiab siv PVC tawv pob tshab zaj duab xis, cov resin yog tus cwj pwm los ntawm nqaim faib ntawm resin polymerization degree los xyuas kom meej nws zoo heev plasticizing kev ua tau zoo thiab zoo txhua yam khoom.Resin ntses qhov muag thiab impurities tsawg, cov khoom "cov ntsiab lus crystal" tsawg dua, zoo heev transmittance. .
Polyvinyl chloride (PVC) resin yog lub siab polymer uas tsim los ntawm polymerization ntawm ethylene.Suspension polymerization yog siv los ua cov txheej txheem kev lag luam polymerization.Nws feem ntau yog ib qho khoom uas tuaj yeem ua kom mos los ntawm cua sov.Thaum rhuab, nws feem ntau muaj qhov kub thiab txias ntawm melting lossis softening, thiab tuaj yeem nyob rau hauv lub xeev cov yas ntws raws li qhov kev txiav txim ntawm sab nraud quab yuam.Lub Hoobkas tuaj yeem ntxiv cov yas yas lossis lwm cov koom haum kom ua tau raws li qhov yuav tsum tau ua raws li kev ua tau zoo ntawm cov khoom yas.
Qib S-1300 feem ntau yog siv los tsim cov khoom lag luam siab zog, cov ntaub ntawv xovxwm, nruj thiab yoog raws extrusion molding thiab insulating cov ntaub ntawv, thiab lwm yam xws li nyias zaj duab xis, nyias phaj, tawv tawv, hlau, cable sheath thiab mos txhua yam profiles.
