Thaum cov calcium thiab zinc composite stabilizer sib xyaw ua ke, zinc xab npum yuav tau nrog ob daim ntawv cog lus hloov thaum hloov allyl chloride. Qhov no nyob rau hauv lem rhuav tshem cov qauv polyene thiab tiv thaiv tsis muaj xim.
Txawm li cas los xij, zinc chloride yuav precipitate hauv PVC, uas muaj cov nyhuv catalytic acceleration ntawm HCl tshem tawm, ua rau cov khoom sib xyaw ua ke tsis ruaj khov, yog li ntawd blackening ua rau bridging.
Calcium fertilizer hloov zinc chloride rau hauv zinc xab npum tom qab qhov kev ua ntawm zinc xab npum thiab polyvinyl chloride stabilized chlorine atoms raws li cov tshuaj tiv thaiv ob zaug decomposition, uas activates zinc xab npum ntawm ib sab tes thiab activates zinc xab npum ntawm qhov tod tes los tiv thaiv kev puas tsuaj ntawm zinc. tshuaj chloride. Ntau cov organic tebchaw tuaj yeem txhim kho cov xim thawj zaug ntawm cov khoom siv tes ua, yog li lawv feem ntau siv los ua cov tshuaj tiv thaiv kab mob kom them nyiaj rau qhov tsis muaj xim ntawm calcium thaum ntxov thiab zinc stabilizers.
Polyols kuj tseem siv hauv PVC calcium zinc stabilizers.
Kev ua haujlwm ntawm polyols yog los tiv thaiv kev puas tsuaj. Tsis tas li ntawd, nyob rau hauv catalytic kev txiav txim ntawm hlau ntsev, polyols kuj tseem tuaj yeem hloov cov pab pawg acrylic thiab txhim kho thawj xim ntawm calcium zinc composite stabilizer, tab sis cov cuab yeej compacting loj cuam tshuam rau daim ntawv thov ntawm polyols, thiab daim ntawv thov ntawm polyols hauv PVC crafts nrog siab. kev cai rwb thaiv tsev yog txwv.
