Iziqinisi ze-calcium zinc ezingamanzi, njengohlobo lwezixhobo ezisebenzayo ezinokukwazi ukucubungula iimveliso ezahlukeneyo ze-PVC ezithambileyo, zisetyenziswe kakhulu kwiibhanti zokuhambisa ze-PVC, iithoyi ze-PVC, ifilimu ye-PVC, iiprofayili ezikhutshiweyo, izihlangu kunye nezinye iimveliso. Iziqinisi ze-calcium zinc ezingamanzi zinobuhlobo nokusingqongileyo kwaye azinabungozi, zinozinzo oluhle kakhulu lobushushu, ukusasazeka, ukumelana nemozulu kunye neempawu zokulwa nokwaluphala.
Izinto eziphambili ezisetyenziswa kwi-calcium zinc stabilizers ziquka: iityuwa ze-organic acid ze-calcium kunye ne-zinc, izinyibilikisi kunyeizinto ezincedisayo zokuqinisa ubushushu ezisebenzisa izinto eziphilayo.
Emva kokusetyenziswa kwe-calcium kunye ne-zinc organic acid salts, indlela ephambili yokuzinzisa yimpembelelo yokusebenzisana kwe-calcium kunye ne-zinc organic acid salts. Ezi zinc salts ziyakwazi ukuvelisa i-Lewis acid metal chloride ZnCl2 xa zifunxa i-HCl. I-ZnCl2 inempembelelo enamandla yokubangela ukubola kwe-PVC, ngoko ke ikhuthaza i-dehydrochlorination ye-PVC, nto leyo ekhokelela ekubola kwe-PVC ngexesha elifutshane. Emva kokudityaniswa, impembelelo yokubangela ukubola kwe-ZnCl2 kwi-PVC iyathintelwa nge-replacement reaction phakathi kwe-calcium salt kunye ne-ZnCl2, enokuthintela ngempumelelo ukutsha kwe-zinc, iqinisekise ukusebenza kakuhle kombala kwangethuba kwaye iphucule uzinzo lwe-PVC.
Ukongeza kwisiphumo esiqhelekileyo sokusebenzisana esikhankanyiweyo apha ngasentla, isiphumo sokusebenzisana kwezinto ezixhasa ubushushu ezincedisayo ze-organic kunye nezinto ezixhasa ubushushu eziphambili kufuneka ziqwalaselwe xa kusenziwa izinto ezixhasa ubushushu ezisebenzisa i-calcium zinc, nto leyo ekwayiyona nto iphambili kuphando nophuhliso lwezinto ezixhasa ubushushu ezisebenzisa i-calcium zinc.
