Pvc cov ntawv tawv yog ua los ntawm polyvinyl chloride resin nrog qee yam kev pab, thiab yog tsim los ntawm extrusion, calendering thiab lwm txoj kev ua. Nws yog cov khoom ntim ntim uas ua tau raws li kev yuav tsum tau kho mob.

Cov ntaub ntawv nyoos ntawm PVC tawv daim ntawv tsuas yog suav nrog PVC Resin, lub stababilizer, Ua Khoom, txhawb tus neeg sawv cev, kua npluas, yas yas, lwm.
1. Vim yog cov cai muaj kev nyab xeeb ntawm Kws muag tshuaj PVC Rigid Cov Ntawv, Lub ntsiab lus VCM ntawm cov xaiv tau PVC Resin yuav tsum tsawg dua
5thiab / cm2
2. Stabilizer txoj haujlwm ntawm stabilizer yog txhawm rau tiv thaiv cov decomposition ntawm polyvinyl chloride ntawm qhov kub, kom cov txheej txheem ua haujlwm tuaj yeem nqa tawm ib txwm.
Cov cua sov stabilizers siv nyob rau hauv kev ua tshuaj ntawm cov tshuaj PVC feem ntau yog organic tins, Tab sis tsuas yog methyl tin mercaptide thiab octyl Tin tuaj yeem siv rau rigid PVC los xij.
3. Ntxiv dag zog rau tus neeg saib xyuas tshuaj PVC yas muaj qhov tsis zoo loj yog nws tus brittleness, uas yuav cuam tshuam nws siv. rau
Txhawm rau txhim kho nws cov brittleness, Tus neeg sawv cev txhawb nqa (Kuj tseem hu ua Kev Cuam Tshuam Hloov Kho) yuav tsum tau ntxiv thaum ua kom txhim kho nws qhov kev cuam tshuam lub zog thiab ua kom cov kev siv qub hauv cov txheej txheem theem nrab. Tam sim no, Qhov cuam tshuam loj me hloov hauv Suav teb yog MSB (methyl methacrylate-butadiene-styrene copolymer).
