Ua kua calcium zinc stabilizers, raws li hom khoom siv ua haujlwm nrog kev muaj peev xwm ua cov khoom siv ntau hom PVC cov khoom ua si, PVC Zaj duab xis, extruded profiles, cov khau khiab thiab lwm yam khoom. Ua kua calcium zinc stabilizers yog ib puag ncig phooj ywg thiab tsis muaj tshuaj lom, nrog cov kev sib cais ua kom zoo nkauj, huab cua tsis kam thiab tiv thaiv kev laus.
Lub ntsiab ntawm cov kua calcium zinc stabilizers muaj: organic acid ntsev ntawm cov calcium thiab zinc, cov kuab tshuaj thiaborganic uxiliate kub stabilizersCov.
Tom qab cov compound siv ntawm calcium thiab zinc organic acid ntsev, lub ntsiab ruaj khov mechanism yog lub synergistic muaj txiaj ntsig ntawm cov calcium thiab zinc organic accet ntsev. Cov ntsev no DINT yog ib qho los tsim Lewis Acid hlau CLNL2 thaum nqus hcL. ZNCL2 muaj cov txuj ci muaj zog ntawm kev ua kom muaj kev cuam tshuam ntawm PVC, yog li nws txhawb nqa lub dehydroforination ntawm PVC, uas ua rau muaj kev cuam tshuam ntawm PVC hauv lub sijhawm luv. Tom qab compounding, catalytic cov nyhuv ntawm zncl2 ntawm qhov kev cuam tshuam los ntawm kev hloov pauv ntawm calcium kev ua tau zoo ntawm cov xim calcium, kom ua tau zoo heev xim zoo nkauj thiab txhim kho kev ruaj ntseg ntawm PVC.
Ntxiv rau cov nyhuv dav dav tau hais saum toj no, cov nyhuv synergicy ntawm cov khoom siv thaum muaj cov kev tshawb fawb ua kua.
