Isiqinisi se-calcium zinciyingxenye ebalulekile ekukhiqizweni kwemikhiqizo ye-PVC (polyvinyl chloride). I-PVC iyipulasitiki ethandwayo esetshenziswa ezinhlobonhlobo zezicelo, kusukela ezintweni zokwakha kuya emikhiqizweni yabathengi. Ukuqinisekisa ukuqina nokusebenza kwesikhathi eside kwe-PVC, iziqinisi zokushisa zengezwa ezintweni ngesikhathi senqubo yokukhiqiza. Isiqinisi sokushisa esivamile esisetshenziswa ekukhiqizweni kwe-PVC yi-calcium zinc stabilizer.
Ama-calcium zinc stabilizer asetshenziselwa ukuvimbela i-PVC ukuthi yonakale emazingeni okushisa aphezulu. Asebenza ngokusabela nama-athomu e-chlorine ku-PVC, okusiza ukuvimbela i-hydrochloric acid ukuthi yakheke ngesikhathi sokushisa. Lokhu kusabela kusiza futhi ukugcina izakhiwo ze-PVC zemishini nezomzimba, ukuqinisekisa ukuthi izinto zihlala zizinzile futhi ziqinile kuyo yonke impilo yazo yokusebenza.
Enye yezinzuzo eziyinhloko zokusebenzisa iziqinisi ze-calcium zinc ekukhiqizweni kwe-PVC yikhono lazo lokunikeza ukuzinza okuhle kakhulu kokushisa. Lokhu kusho ukuthi imikhiqizo ye-PVC equkethe iziqinisi ze-calcium zinc iyakwazi ukumelana namazinga okushisa aphezulu ngaphandle kokulahlekelwa ubuqotho besakhiwo noma izici zokusebenza. Ngakho-ke, le mikhiqizo ivame ukusetshenziswa ezisetshenziswa lapho ukumelana nokushisa kubalulekile, njengezinto zokwakha, izingxenye zezimoto, kanye nokufakwa kukagesi.
Ngaphezu kokunikeza ukuzinza kokushisa, iziqinisi ze-calcium zinc nazo zinikeza ukumelana okuhle kakhulu kwe-UV. Lokhu kusho ukuthi imikhiqizo ye-PVC equkethe lezi ziqinisi ingamelana nokuchayeka elangeni isikhathi eside ngaphandle kokuwohloka noma ukuqhekeka. Lokhu kubaluleke kakhulu ekusetshenzisweni kwangaphandle, njengezinto zokwakha, ozimele bamafasitela kanye nefenisha yangaphandle, lapho ukuchayeka kwe-UV kuyisici esiqhubekayo.
Omunye umsebenzi obalulekile weziqinisi ze-calcium zinc ekukhiqizweni kwe-PVC ukuthuthukisa ukusebenza kokucubungula okuphelele kanye nezakhiwo zemishini zento. Ngokusebenzisa lezi ziqinisi, abakhiqizi bayakwazi ukuthola amandla okuhlangana nokuncibilika okungcono, kanye nokwanda kokumelana nokushayisana kanye nokuguquguquka. Lokhu kukhiqiza imikhiqizo ye-PVC esezingeni eliphezulu engamelana nobunzima bokusetshenziswa kwansuku zonke ngaphandle kokulahlekelwa ukuma noma izakhiwo zayo.
Ngaphezu kwezinzuzo zobuchwepheshe, iziqinisi ze-calcium-zinc nazo zinezinzuzo zemvelo. Ngokungafani nezinye izinhlobo zeziqinisi zokushisa, njengeziqinisi ezisekelwe ku-lead, iziqinisi ze-calcium zinc azinabo ubuthi futhi zinobungani nemvelo. Lokhu kuzenza zibe ukukhetha okuphezulu kubakhiqizi nabathengi abafuna izinto ezihlala isikhathi eside neziphephile. Ngaphezu kwalokho, ukusetshenziswa kweziqinisi ze-calcium zinc ekukhiqizweni kwe-PVC kusiza ukuqinisekisa ukuhambisana nemithethonqubo nezindinganiso zemvelo, okwenza kube inketho ekhangayo ezinkampanini ezifuna ukunciphisa ukunyathela kwazo kwemvelo.
Sekukonke, iziqinisi ze-calcium zinc zidlala indima ebalulekile ekukhiqizweni kwemikhiqizo ye-PVC ngokuhlinzeka ngokuqina okuhle kakhulu kokushisa, ukumelana ne-UV kanye nezakhiwo zemishini. Ukusetshenziswa kwazo ekukhiqizweni kwe-PVC kuvumela ukudalwa kwezinto ezihlala isikhathi eside nezihlala isikhathi eside ezingamelana nezimo eziningi zemvelo kanye nezimo zokusetshenziswa. Njengoba isidingo sezinto ezisezingeni eliphezulu nezihlala isikhathi eside siqhubeka sikhula, ukubaluleka kweziqinisi ze-calcium-zinc ekukhiqizweni kwe-PVC cishe kuzokhula, okwenza kube yingxenye ebalulekile embonini yepulasitiki.
