1) Sim xaiv cov khoom siv ntxiv thiab cov khoom siv raw nrog cov thermal stability thiab volatile tsis kam (PVC, CPE, ACR, lubricants, thiab lwm yam);
2) Cov tsos thiab qhov loj me me ntawm cov khoom siv tsis zoo (calcium carbonate, hmoov dawb, hydrotalc, zeolite, thiab lwm yam) txhawm rau txhim kho qhov zoo ntawm qhov chaw pretreatment;
3) Qhov zoo thiab ntau npaum li cas ntawm stabilizer (tseem) kom ntseeg tau tias cov khoom muaj thermal stability; 4) Xaiv cov khoom siv raw uas tsis tshua muaj hluav taws xob vim muaj cua sov txo;
Compatibility ntawm calcium thiab zinc stabilizer Cheebtsam nrog resins
1) Ordinary calcium stearate yog ib qho yooj yim rau tshuaj tsuag thiab zinc stearate, thiab kev sib raug zoo nrog polyvinyl chloride tsis zoo. Qee cov organic auxiliary stabilizers kuj yooj yim los nag. Calcium ntsev thiab zinc ntsev tsim los ntawm ntau lub teeb hauv paus acid yog Lewis acid qauv, thiab kev sib raug zoo nrog polyvinyl chloride zoo heev;
2) Quaternary tetraol tuaj yeem cuam tshuam zinc hlawv, tab sis vim nws qhov hnyav molecular me me thiab yooj yim tsiv teb tsaws, nws yuav tsum tau acetated.
3) Kev sib xyaw ua ke ntawm cov khoom siv roj hmab thiab PVC tsis zoo, thiab nag lossis daus yuav muaj zog.
Qhov saturation ntawm cov khoom xyaw hauv cov mis
