Mmetụta synergistic nke organic tin na ntụ ntụ calcium zinc stabilizers na polyvinyl chloride (PVC):
Organic tin stabilizers (thiol methyl tin) bụ ụdị PVC okpomọkụ a na-ejikarị eme ihe. Ha na-emeghachi omume na acidic hydrogen chloride (HCl) na PVC na-emepụta nnu inorganic na-adịghị emerụ ahụ (dị ka tin chloride), si otú ahụ na-egbochi mkpokọta HCl na ibelata nbibi na odo nke ihe PVC.
Powder calcium zinc stabilizer bụ ngwakọta nke calcium na zinc salts, na-agbakwunyekarị n'ụdị ntụ ntụ dị mma na PVC. Ma calcium na zinc ion nwere ike ime ka PVC kwụsie ike. Calcium ion nwere ike imebi ihe acidic emepụtara na PVC wee mepụta ogige nnu calcium kwụsiri ike. Zinc ion na-emeghachi omume na hydrogen peroxide (HCl) na PVC iji mepụta ogige inorganic na-adịghị emerụ ahụ ma gbochie mkpokọta HCl.
Mgbe tin organic na ntụ ntụ calcium zinc stabilizers bi na PVC, ha nwere ike ịkwalite ibe ha ma melite ikike ịgwọ HCl. Organic tin nwere ike inyekwu ikike nkwụsịtụ iji mebie HCl ndị ọzọ emepụtara, ebe calcium zinc stabilizers powdered nwere ike inyekwu calcium na zinc ion, na-egbochi nchikota HCl. Site na mmetụta a synergistic, organic tin na ntụ ntụ calcium zinc stabilizers nwere ike welie thermal nkwụsi ike nke PVC ihe, melite ọrụ ndụ ha na arụmọrụ kwụsie ike.
Ekwesiri ighota na ego na oke nke organic tin na calcium zinc stabilizers kwesiri ka edozi ya nke oma dika ihe a choro na ebe eji eme ihe nke ngwaahịa PVC, iji nweta mmetụta synergistic kacha mma. N'otu oge ahụ, ọ dị mkpa ịṅa ntị na nchekwa na gburugburu ebe obibi n'oge eji iji zere mmetụta ọjọọ na ahụike mmadụ na gburugburu ebe obibi.
