I-calcium zinc stabilizeriyingxenye ebalulekile ekukhiqizeni imikhiqizo ye-PVC (i-polyvinyl chloride). I-PVC iyipulasitiki ethandwayo esetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza, kusukela ezintweni zokwakha kuya emikhiqizweni yabathengi. Ukuqinisekisa ukuqina nokusebenza kwesikhathi eside kwe-PVC, izinzisi zokushisa zengezwa endabeni ngesikhathi senqubo yokukhiqiza. I-stabilizer evamile yokushisa esetshenziswa ekukhiqizeni i-PVC i-calcium zinc stabilizer.
Iziqinisi ze-calcium zinc zisetshenziselwa ukuvimbela i-PVC ekuwohlokeni emazingeni okushisa aphezulu. Basebenza ngokusabela ngama-athomu e-chlorine ku-PVC, esiza ukuvimbela i-hydrochloric acid ekubunjweni ngesikhathi sokushisa. Lokhu kusabela kusiza futhi ukugcina izakhiwo ze-PVC zemishini nezomzimba, iqinisekisa ukuthi impahla ihlala izinzile futhi ihlala isikhathi eside kuyo yonke impilo yayo yesevisi.
Enye yezinzuzo eziyinhloko zokusebenzisa i-calcium zinc stabilizers ekukhiqizeni kwe-PVC yikhono labo lokuhlinzeka ngokusimama okuhle kakhulu kokushisa. Lokhu kusho ukuthi imikhiqizo ye-PVC equkethe i-calcium zinc stabilizer iyakwazi ukumelana namazinga okushisa aphezulu ngaphandle kokulahlekelwa ubuqotho bayo besakhiwo noma izici zokusebenza. Ngakho-ke, le mikhiqizo ivame ukusetshenziselwa izinhlelo zokusebenza lapho ukumelana nokushisa kubalulekile, njengezinto zokwakha, izingxenye zezimoto, nokufakwa kukagesi.
Ngaphezu kokunikeza ukuzinza okushisayo, iziqinisi ze-calcium zinc nazo zinikeza ukumelana okuhle kwe-UV. Lokhu kusho ukuthi imikhiqizo ye-PVC equkethe lezi ziqinisi ingamelana nokuchayeka isikhathi eside elangeni ngaphandle kokwehliswa isithunzi noma ukuba brittle. Lokhu kubaluleke kakhulu ezinhlelweni zokusebenza zangaphandle, njengezinto zokwakha, amafreyimu amafasitela kanye nefenisha yangaphandle, lapho ukuvezwa kwe-UV kuyisici esiqhubekayo.
Omunye umsebenzi obalulekile we-calcium zinc stabilizers ekukhiqizeni kwe-PVC ukuthuthukisa ukusebenza okuphelele kokucubungula kanye nezakhiwo zemishini zento. Ngokusebenzisa lezi ziqinisi, abakhiqizi bayakwazi ukufeza ukuhlanganisa okungcono namandla okuncibilika, kanye nokwenyuka kokumelana nomthelela nokuguquguquka. Lokhu kukhiqiza imikhiqizo ye-PVC yekhwalithi ephezulu engamelana nobunzima bokusetshenziswa kwansuku zonke ngaphandle kokulahlekelwa ukwakheka noma izakhiwo zayo.
Ngaphezu kwezinzuzo zobuchwepheshe, i-calcium-zinc stabilizers nayo inezinzuzo zemvelo. Ngokungafani nezinye izinhlobo zezinzisi zokushisa, njengeziqinisi ezisekelwe kumthofu, iziqinisi ze-calcium zinc azinabuthi futhi azihambisani nemvelo. Lokhu kubenza babe ukukhetha okuphezulu kubakhiqizi nabathengi abafuna izinto ezisimeme neziphephile. Ukwengeza, ukusetshenziswa kwe-calcium zinc stabilizers ekukhiqizeni kwe-PVC kusiza ukuqinisekisa ukuhambisana nemithetho nezindinganiso zemvelo, okwenza kube inketho ekhangayo ezinkampanini ezifuna ukunciphisa indawo yazo yemvelo.
Sekukonke, i-calcium zinc stabilizers idlala indima ebalulekile ekukhiqizeni imikhiqizo ye-PVC ngokunikeza ukuqina okuhle kakhulu kokushisa, ukumelana ne-UV kanye nezakhiwo zemishini. Ukusetshenziswa kwabo ekukhiqizeni kwe-PVC kuvumela ukudala izinto ezihlala isikhathi eside nezihlala isikhathi eside ezingamelana nezimo eziningi zemvelo kanye nezimo zokusetshenziswa. Njengoba isidingo sezinto ezisezingeni eliphezulu nezisimeme siqhubeka sikhula, ukubaluleka kwe-calcium-zinc stabilizers ekukhiqizeni kwe-PVC kungenzeka kukhule, okwenza kube yingxenye ebalulekile yemboni yepulasitiki.
