Tšusumetso ea tšebelisano-'moho ea tin ea organic le phofo ea calcium zinc stabilizers ho polyvinyl chloride (PVC):
Li-stabilizer tsa tin ea tlhaho (thiol methyl tin) ke mofuta o sebelisoang haholo oa PVC stabilizer. Li arabela le asiti ea hydrogen chloride (HCl) ho PVC ho etsa matsoai a sa pheleng a se nang kotsi (joalo ka tin chloride), ka hona li thibela ho bokellana ha HCl le ho fokotsa ho senyeha le ho sootho ha thepa ea PVC.
Phofo ea calcium zinc stabilizer ke motsoako oa letsoai la calcium le zinc, hangata e eketsoa ka mokhoa oa phofo e ntle ho PVC. Li-ion tsa calcium le zinc ka bobeli li na le bokhoni ba ho tsitsisa PVC. Li-ion tsa calcium li ka fokotsa lintho tse nang le asiti tse hlahisoang ho PVC 'me tsa etsa metsoako e tsitsitseng ea letsoai la calcium. Li-ion tsa zinc li arabela ka hydrogen peroxide (HCl) ho PVC ho etsa metsoako e se nang kotsi ea lintho tse phelang le ho thibela ho bokellana ha HCl.
Ha di-stabilizer tsa calcium zinc tsa organic le phofo di le teng ka hara PVC, di ka kgothatsana mme tsa ntlafatsa bokgoni ba ho phekola HCl. Di-organic tin di ka fana ka bokgoni bo eketsehileng ba ho fokotsa ho senyeha ha HCl e ngata e hlahiswang, ha di-stabilizer tsa calcium zinc tsa organic di ka fana ka di-ion tse ngata tsa calcium le zinc, e leng se thibelang ho bokellana ha HCl. Ka phello ena ya tshebedisano mmoho, di-stabilizer tsa calcium zinc tsa organic le phofo di ka ntlafatsa botsitso ba mocheso ba thepa ya PVC, tsa ntlafatsa bophelo ba tsona ba tshebeletso le botsitso ba tshebetso.
Ho lokela ho hlokomeloa hore bongata le karolo ea li-stabilizer tsa tin ea organic le calcium zinc li hloka ho fetoloa ka nepo ho latela litlhoko tse ikhethileng le tikoloho ea ts'ebeliso ea lihlahisoa tsa PVC, e le ho fihlela phello e ntle ka ho fetisisa ea tšebelisano-'moho. Ka nako e ts'oanang, ho hlokahala ho ela hloko litaba tsa polokeho le tikoloho nakong ea ts'ebeliso ho qoba litlamorao tse mpe bophelong ba batho le tikolohong.
