Cov kua calcium zinc stabilizers, ua ib hom khoom siv ua haujlwm nrog lub peev xwm los ua ntau yam khoom mos PVC, tau siv dav hauv PVC conveyor siv, PVC cov khoom ua si, PVC zaj duab xis, extruded profiles, khau thiab lwm yam khoom. Cov kua calcium zinc stabilizers yog ib puag ncig zoo thiab tsis muaj tshuaj lom, nrog kev ruaj khov thermal zoo heev, kev sib kis, huab cua tiv taus thiab cov khoom tiv thaiv kev laus.
Cov khoom tseem ceeb ntawm cov kua calcium zinc stabilizers suav nrog: cov ntsev organic acid ntawm calcium thiab zinc, cov kuab tshuaj thiabcov organic auxiliary heat stabilizers.
Tom qab siv cov ntsev calcium thiab zinc organic acid sib xyaw ua ke, lub hauv paus tseem ceeb ntawm kev ruaj khov yog cov nyhuv synergistic ntawm calcium thiab zinc organic acid ntsev. Cov ntsev zinc no yooj yim tsim Lewis acid hlau chlorides ZnCl2 thaum nqus HCl. ZnCl2 muaj cov nyhuv catalytic muaj zog rau kev puas tsuaj ntawm PVC, yog li nws txhawb nqa dehydrochlorination ntawm PVC, uas ua rau kev puas tsuaj ntawm PVC hauv lub sijhawm luv luv. Tom qab sib xyaw ua ke, cov nyhuv catalytic ntawm ZnCl2 rau kev puas tsuaj ntawm PVC raug txwv los ntawm kev hloov pauv ntawm calcium ntsev thiab ZnCl2, uas tuaj yeem tiv thaiv zinc hlawv, xyuas kom meej tias cov xim thaum ntxov zoo heev thiab txhim kho kev ruaj khov ntawm PVC.
Ntxiv rau qhov cuam tshuam dav dav uas tau hais los saum toj no, qhov cuam tshuam synergistic ntawm cov organic auxiliary heat stabilizers thiab cov thawj stabilizers yuav tsum tau xav txog thaum tsim cov kua calcium zinc stabilizers, uas kuj yog qhov tseem ceeb ntawm kev tshawb fawb thiab kev txhim kho cov kua calcium zinc stabilizers.
