Feem ntau hais lus,Ua kua PVC stabilizershaum rau pob tshab calendered films mas suav nrogMethyl Tin,Calcium-Zincthiab Carium-Zinc stabilizers.
Cov kua dej Methyl Tin stabilizers muaj cov thermal stability zoo thiab tuaj yeem tiv thaiv qhov decomposition ntawm PVC nyob rau hauv high-temperature processing tej yam kev mob, kom ntseeg tau lub pob tshab thiab xim stability ntawm cov khoom. Txawm li cas los xij, lawv cov nqi kuj tseem siab. Hauv qee qhov xwm txheej ntawm daim ntawv thov uas tus nqi ntau dua, cov tuam txhab yuav nrhiav lwm txoj kev daws teeb meem.
PVC Barium Zinc stabilizers yog ib hom thermal stabilizers nrog kev ua tau zoo heev. Rau cov pob tshab calendered films, lawv tuaj yeem muab cov xim zoo rau thawj zaug, ua rau cov yeeb yaj kiab kom muaj qhov zoo nkauj thiab xim thaum ntxov ntawm kev ua haujlwm. Lawv kuj muaj qhov ua tau zoo thermal stability ntev thiab tuaj yeem ua kom ntseeg tau tias cov yeeb yaj kiab tsis tuaj yeem ua rau tsis muaj xim thiab kev laus thaum siv tom ntej. Lub caij no, lubricity ntawm barium-zinc stabilizers yog nruab nrab, uas pab cov khoom ntws thaum lub sij hawm ua thiab ua rau cov txheej txheem calendering smoother thiab txhim kho efficiency ntau lawm.
PVC Calcium Zinc stabilizers, raws li cov neeg sawv cev ntawm ib puag ncig tus phooj ywg stabilizers, yog maj mam dhau los ua lub ntsiab hauv kev lag luam. Lawv qhov txiaj ntsig loj tshaj plaws yog nyob rau hauv kev ua tus phooj ywg ib puag ncig thiab tsis muaj tshuaj lom, uas ua raws li cov qauv ntawm kev tiv thaiv ib puag ncig kom nruj rau cov khoom yas. Nyob rau hauv kev tsim cov pob tshab calendered films, calcium-zinc stabilizers tuaj yeem ua rau cov yeeb yaj kiab nrog cov pob tshab thiab cov huab cua zoo heev. Txawm hais tias cov yeeb yaj kiab raug cuam tshuam rau qhov chaw sab nraum zoov ntev ntev, lawv tuaj yeem tiv thaiv kev laus thiab cov teeb meem embrittlement los ntawm yam xws li ultraviolet rays thiab oxygen, yog li ua rau lub neej ntev ntawm cov yeeb yaj kiab.
