Mmetụta mmekọrịta nke ihe ndị na-eme ka calcium zinc kwụsie ike na polyvinyl chloride (PVC)

Mmetụta mmekọrịta nke ihe ndị na-eme ka calcium zinc kwụsie ike na polyvinyl chloride (PVC):

Ihe ndị na-eme ka tin dị ọcha sie ike (thiol methyl tin) bụ ụdị ihe na-eme ka okpomọkụ PVC sie ike nke a na-ejikarị eme ihe. Ha na-emeghachi omume na acidic hydrogen chloride (HCl) dị na PVC iji mepụta nnu ndị na-adịghị emerụ ahụ (dịka tin chloride), si otú a na-egbochi mkpokọta HCl ma na-ebelata mmebi na ịcha odo nke ihe PVC.

Ntụ ntụ calcium zinc stabilizer bụ ngwakọta nke nnu calcium na zinc, nke a na-agbakwụnyekarị n'ụdị ntụ ntụ dị nro na PVC. Ma ion calcium na zinc nwere ike ime ka PVC kwụsie ike. ion calcium nwere ike iwepụ ihe acidic emepụtara na PVC ma mepụta ngwakọta nnu calcium kwụsiri ike. ion zinc na-emeghachi omume na hydrogen peroxide (HCl) na PVC iji mepụta ngwakọta inorganic na-adịghị emerụ ahụ ma gbochie mkpokọta HCl.

Mgbe ihe ndị na-eme ka calcium zinc sie ike na tin organic na ntụ ntụ jikọtara ọnụ na PVC, ha nwere ike ịkwalite ibe ha ma melite ikike ịgwọ HCl. Tin organic nwere ike inye ikike ọzọ na-egbochi mmebi nke HCl ndị a na-emepụta, ebe ihe ndị na-eme ka calcium zinc sie ike nwere ike inye calcium na zinc ion karịa, na-egbochi mkpokọta HCl. Site na mmetụta a na-eme ka calcium zinc sie ike na tin organic na ntụ ntụ nwere ike ime ka nkwụsi ike okpomọkụ nke ihe PVC dịkwuo mma, melite ndụ ọrụ ha na nkwụsi ike arụmọrụ ha.

E kwesịrị ịmara na a ga-agbanwe ọnụọgụ na oke nke ihe ndị na-eme ka ígwè na calcium zinc sie ike n'ụzọ kwesịrị ekwesị dịka ihe achọrọ na gburugburu ebe eji ngwaahịa PVC mee si dị, iji nweta mmetụta kachasị mma. N'otu oge ahụ, ọ dị mkpa ịṅa ntị na nchekwa na nsogbu gburugburu ebe obibi n'oge ojiji iji zere mmetụta ọjọọ na ahụike mmadụ na gburugburu ebe obibi.
