Vim muaj cov hlau sib txawv, ntau yam hlau soaps tsim los ntawm calcium thiab zinc composite stabilizer muaj peev xwm sib txawv rau PVC. Ntxiv rau calcium zinc complex stabilizer, muaj ntau yam tshiab calcium zinc complex stabilizer. Yog tias zinc lossis tin xab npum nrog kev ua haujlwm siab yog ua ke nrog barium, cadmium, zinc thiab lwm yam tshuaj soaps, cov nyhuv synergistic tuaj yeem tsim kom tau txais txiaj ntsig zoo.
Tam sim no, ob qho tib si sab hauv thiab sab nrauv kev lag luam tsom rau kev txhim kho thiab kev siv cov calcium thiab zinc stabilizer, calcium thiab zinc complex stabilizer yog ib qho ntawm ntau hom kev cog lus. Cov khoom siv calcium-zinc kub calcium-zinc stabilizer muaj tus nqi qis thiab lubricity zoo. Tsis tas li ntawd, nws cov hmoov txhuas ntsev hmoov zoo sib xws hauv cov mis, lubrication mechanism thiab kev siv tshuab.
Nws yooj yim dua los hloov cov ntsev ntsev, tab sis nws cov thermal stability tsis zoo, thiab zinc xab npum feem ntau ua rau cov khoom "zinc hlawv". Nyob rau hauv cov ntaub ntawv ntawm kev ua tau zoo ntawm cov khoom yuav tsum tau, kev siv cov zinc xab npum kuj yuav raug txwv. Calcium zinc complex stabilizer muab faib ua cov khoom thiab cov kua ob hom. Hauv kev ua cov khoom siv PVC, cov tshuaj chloride tsim los ntawm cov tshuaj tiv thaiv ntawm HCl tso tawm los ntawm PVC thiab zinc tebchaw yog qhov tseeb catalyst rau degradation ntawm PVC polymeric cov ntaub ntawv, thiab lub luag hauj lwm ntawm calcium carboxylate yog hais tias ib zaug lub saum toj no zinc polymeric complex yog tsim, Nws tuaj yeem cuam tshuam HCl thiab inhibit qhov hloov pauv ntawm zinc polymeric complex rau zinc chloride, kom cov polymer tuaj yeem tau txais kev ruaj ntseg. Nws yog ib hom kub calcium zinc stabilizer rau PVC ua.
