Phello ea synergistic ea organic tin le powder calcium zinc stabilizers ho polyvinyl chloride (PVC):
Organic tin stabilizers (thiol methyl tin) ke mofuta o sebelisoang hangata oa PVC mocheso stabilizer. Li itšoara ka acidic hydrogen chloride (HCl) ho PVC ho etsa matsoai a se nang kotsi (joaloka tin chloride), kahoo a thibela ho bokellana ha HCl le ho fokotsa ho senyeha le ho ba mosehla ha thepa ea PVC.
Powder calcium zinc stabilizer ke motswako wa calcium le matswai a zinki, hangata a eketswang ka mokgwa wa phofo e ntle ho PVC. Ka bobeli li-ion tsa calcium le zinki li na le bokhoni ba ho tsitsisa PVC. Li-ion tsa calcium li ka fokotsa lintho tse nang le asiti tse hlahisoang ka PVC 'me tsa etsa metsoako e tsitsitseng ea letsoai la calcium. Li-ion tsa zinki li sebetsana le hydrogen peroxide (HCl) ho PVC ho etsa metsoako e se nang kotsi le ho thibela ho bokellana ha HCl.
Ha organic tin le powder calcium zinc stabilizers li le hammoho PVC, li ka khothaletsana le ho ntlafatsa bokhoni ba ho phekola HCl. Organic tin e ka fana ka matla a eketsehileng a ho fokotsa matla a ho senya HCl e ngata e hlahisoang, ha li-calcium zinc stabilizers tse phofshoana li ka fana ka li-ion tse ngata tsa calcium le zinki, ho thibela ho bokellana ha HCl. Ka phello ena ea synergistic, organic tin le powder calcium zinc stabilizers li ka ntlafatsa botsitso ba mocheso oa thepa ea PVC, ea ntlafatsa bophelo ba bona ba ts'ebeletso le botsitso ba ts'ebetso.
Hoa lokela ho hlokomeloa hore palo le karolo ea li-organic tin le calcium zinc stabilizer li hloka ho fetoloa ka mokhoa o utloahalang ho ea ka litlhoko tse khethehileng le tikoloho ea tšebeliso ea lihlahisoa tsa PVC, e le ho finyella phello e ntle ka ho fetisisa ea synergistic. Ka nako e ts'oanang, hoa hlokahala ho ela hloko litaba tsa polokeho le tikoloho nakong ea ts'ebeliso ho qoba litlamorao tse mpe bophelong ba batho le tikolohong.
