1) Gcoba futhi wenze i-HCL ingabi namandla, vimbela umphumela wayo we-auto catalytic. Lolu hlobo lwe-stabilizer luhlanganisa usawoti oholayo, insipho yensimbi ye-organic acid, ama-organotin compounds, ama-epoxy compounds, usawoti we-inorganic, nosawoti we-thiol wensimbi. Bangasabela nge-HCL futhi bavimbele ukusabela kwe-PVC ukuze kukhishwe i-HCL.
2) Ukushintsha ama-athomu e-chlorine angazinzile kuma-molecule e-PVC kuvimbela ukukhishwa kwe-HCL. Uma i-organic tin stabilizer ixhuma nama-athomu e-chlorine angazinzile wama-molecule e-PVC, i-organic tin izothathelwa indawo ama-athomu e-chlorine angazinzile emzimbeni wokuxhumanisa.
3) Ukusabela okungeziwe ngesakhiwo se-polyene kuphazamisa ukwakheka kwesistimu enkulu ehlanganisiwe futhi kunciphisa umbala. Usawoti noma ama-esters e-asidi engagcwalisiwe aqukethe amabhondi aphindwe kabili, abhekana nokusabela kokwengezwa kwe-diene nama-molecule e-PVC ngokuhlanganisa amabhondi akabili, abese ephazamisa ukwakheka kwawo okuhlanganisiwe futhi avimbele ukushintsha kombala.
I-4) Ukubamba ama-radicals wamahhala nokuvimbela ukusabela kwe-oxidation, lesi siqinisi esishisayo singaba nomphumela owodwa noma eminingana.
I-stabilizer yokushisa efanelekile ye-PVC kufanele ibe into esebenzayo noma ingxube yezinto ezingakwazi ukufeza le misebenzi elandelayo: okokuqala, shintsha izinto ezisebenzayo nezingazinzile; Okwesibili ukumunca nokwenza i-HCL ekhishwe ngesikhathi sokucutshungulwa kwe-PVC, kuqedwe umphumela wokuwohloka ozenzakalelayo we-HCL; Okwesithathu ukuqeda noma ukuvala ama-ion ensimbi nokunye ukungcola okuyingozi okudlala indima edala ukucekelwa phansi; Okwesine, izinhlobo ezihlukahlukene zokusabela kwamakhemikhali zingavimbela ukukhula okuqhubekayo kwamabhondi angagcwele futhi zivimbele ukuwohloka kombala; Okwesihlanu, inomphumela wokuvikela nokuvikela ekukhanyeni kwe-ultraviolet. Ngokuvamile, iziqinisi zokushisa zisetshenziswa ngokuhlanganiswa ngokusekelwe ekusebenzeni kwazo okuqondile, futhi ukusetshenziswa kwazo ngakunye akuvamile. Ngaphezu kwalokho, izinhlobonhlobo eziningi zisohlobo lwempushana, kanti ezinye zingamakhemikhali anobuthi obukhulu. Ukuze kube lula ukusetshenziswa, ukuvimbela ubuthi othulini, ukunciphisa izinto ezinobuthi noma esikhundleni sazo kufakwe izinto ezingezona ezinobuthi, izinhlobo eziningi zeziqinisi eziyinhlanganisela ziye zathuthukiswa kokubili ngaphakathi nakwamanye amazwe eminyakeni yamuva nje. Isibonelo, i-German Bear brand composite stabilizer series, kanye ne-organic tin noma iziqinisi ze-organic organic ezivela emazweni afana ne-United States, Germany, Japan, kanye ne-Netherlands, zonke zinesabelo esikhulu semakethe e-China. Ngakho-ke, kuyisidingo esiphuthumayo sokuthuthukiswa kwemboni yepulasitiki yaseShayina ukugqugquzela ngokugcwele ukusetshenziswa kwezinzinzisi ezintsha eziyinhlanganisela ezisebenza kahle, ezingabizi kakhulu, ezingenalo uthuli, ezingenabuthi noma ezinobuthi obuphansi.
