Feem ntau, peb xaiv hom stabilizer raws li qhov yuav tsum tau ua ntawm cov khoom hauv cov qauv. Rau kev xaiv cov stabilizers hauv PVC, peb tau sau cov ntsiab lus tseem ceeb hauv qab no:
1.Lead ntsev stabilizers feem ntau yog siv rau hauv cov khoom nruj. Lead ntsev stabilizers muaj thermal stability zoo, hluav taws xob zoo heev, thiab pheej yig. Txawm li cas los xij, lawv yog cov tshuaj lom heev, nquag ua rau cov khoom sib kis, thiab tsuas yog siv los tsim cov khoom opaque.
2. Barium-cadmium stabilizers yog ib hom stabilizer nrog kev ua tau zoo dua. Lawv tau siv dav hauv kev ua liaj ua teb PVC zaj duab xis. Lawv feem ntau siv ua ke nrog barium-cadmium-zinc, organic phosphites, thiab antioxidants.
3.Calcium zinc stabilizers tuaj yeem siv los ua cov khoom tsis muaj tshuaj lom hauv cov khoom ntim khoom noj, cov khoom siv kho mob, thiab cov khoom ntim tshuaj, ntawm lwm cov khoom siv tau yooj yim, lawv qhov ruaj khov yog qhov tsawg, thiab lawv feem ntau siv ua ke nrog polyols thiab antioxidants los txhim kho lawv cov kev ua tau zoo. Tsis tas li ntawd, kev siv cov calcium zinc complex stabil nyob rau hauv cov khoom nruj xws li cov kav dej kuj maj mam ua kom paub tab.
4. Organotin stabilizers muaj kev ua tau zoo thiab tsim nyog rau cov khoom tsis zoo thiab pob tshab PVC. Tshwj xeeb, octyl tin tau dhau los ua qhov ruaj khov rau cov khoom ntim tsis muaj tshuaj lom, tab sis nws kuj kim heev.
5.Epoxy stabilizers feem ntau yog siv los ua cov stabilizers. Thaum siv nrog barium, cadmium, calcium, thiab zinc stabil, lawv tuaj yeem txhim kho lub teeb thiab kub stability.
