I-liquid calcium zinc stabilizers, njengohlobo lwezinto ezisebenzayo ezinekhono lokucubungula imikhiqizo ehlukahlukene ye-PVC ethambile, isetshenziswe kabanzi kumabhande okuthutha e-PVC, amathoyizi e-PVC, ifilimu ye-PVC, amaphrofayili akhishiwe, izicathulo neminye imikhiqizo. I-Liquid calcium zinc stabilizers ihambisana nemvelo futhi ayinabo ubuthi, inokuqina okuhle kakhulu kokushisa, ukuhlakazeka, ukumelana nesimo sezulu kanye nezindawo zokulwa nokuguga.
Izingxenye eziyinhloko ze-liquid calcium zinc stabilizers zihlanganisa: usawoti we-organic acid we-calcium ne-zinc, ama-solvents kanyeorganic asizayo ukushisa stabilizer.
Ngemuva kokusetshenziswa kwe-calcium ne-zinc organic acid usawoti, indlela eyinhloko yokuzinzisa umphumela we-synergistic we-calcium ne-zinc organic acid usawoti. Lawa masawoti e-zinc ajwayele ukukhiqiza i-Lewis acid metal chloride i-ZnCl2 lapho imunca i-HCl. I-ZnCl2 inomphumela oqinile we-catalytic ekuwohlokeni kwe-PVC, ngakho-ke ikhuthaza ukuchithwa kwe-PVC, okuholela ekulimazeni kwe-PVC ngesikhathi esifushane. Ngemva kokuhlanganiswa, umthelela omkhulu we-ZnCl2 ekonakalisweni kwe-PVC uyavinjelwa ngokusabela kokushintshanisa phakathi kukasawoti we-calcium ne-ZnCl2, okungavimbela ngempumelelo ukusha kwe-zinc, kuqinisekise ukusebenza kahle kombala kwangaphambi kwesikhathi futhi kuthuthukise ukuzinza kwe-PVC.
Ngaphezu komphumela ojwayelekile we-synergistic okukhulunywe ngenhla, umphumela we-synergistic we-organic auxiliary heat stabilizers nama-primary stabilizer kufanele futhi ucatshangelwe lapho kwakhiwa iziqinisi ze-calcium zinc eziwuketshezi, okubuye kugxilwe kuzo ocwaningweni nasekuthuthukisweni kweziqinisi ze-calcium zinc ewuketshezi.
