Isiqinisi se-calcium zinclicandelo elibalulekileyo ekuvelisweni kweemveliso zePVC (polyvinyl chloride). IPVC yiplastiki edumileyo esetyenziswa kwiintlobo ngeentlobo zezicelo, ukusuka kwizinto zokwakha ukuya kwiimveliso zabathengi. Ukuqinisekisa ukuqina nokusebenza kwexesha elide kwePVC, kongezwa izinto ezigcina ubushushu kwizixhobo ngexesha lenkqubo yokuvelisa. Isizinzisi sobushushu esiqhelekileyo esisetyenziswa kwimveliso yePVC yi-calcium zinc stabilizer.
Iziqinisi zecalcium zinc zisetyenziselwa ukuthintela i-PVC ukuba ingonakali xa ishushu kakhulu. Zisebenza ngokuphendula ngeeathom ze-chlorine kwi-PVC, nto leyo enceda ekuthinteleni ukwakheka kwe-hydrochloric acid ngexesha lokufudumeza. Le mpendulo ikwanceda ekugcineni iipropati zoomatshini nezomzimba ze-PVC, ukuqinisekisa ukuba izinto zihlala zizinzile kwaye zihlala ixesha elide kulo lonke ixesha lokusebenza kwayo.
Enye yezona nzuzo ziphambili zokusebenzisa iziqinisi ze-calcium zinc kwimveliso ye-PVC kukuba ziyakwazi ukubonelela ngozinzo oluhle kakhulu lobushushu. Oku kuthetha ukuba iimveliso ze-PVC eziqulethe iziqinisi ze-calcium zinc ziyakwazi ukumelana nobushushu obuphezulu ngaphandle kokulahlekelwa bubume bazo okanye iimpawu zokusebenza. Ke ngoko, ezi mveliso zihlala zisetyenziswa kwiindawo apho ukumelana nobushushu kubalulekile, njengezinto zokwakha, izinto zeemoto, kunye nokufakelwa kombane.
Ukongeza ekuzinzeni kobushushu, iziqinisi ze-calcium zinc zikwabonelela ngokumelana okuhle kakhulu ne-UV. Oku kuthetha ukuba iimveliso ze-PVC eziqulathe ezi ziqinisi zinokumelana nokukhanya kwelanga ixesha elide ngaphandle kokubola okanye ukuqhekeka. Oku kubaluleke kakhulu kwizicelo zangaphandle, ezifana nezixhobo zokwakha, iifreyimu zeefestile kunye nefenitshala yangaphandle, apho ukuvezwa kwe-UV kuyinto eqhubekayo.
Omnye umsebenzi obalulekileyo wezinzisi ze-calcium zinc kwimveliso ye-PVC kukuphucula ukusebenza kwayo yonke into kunye neempawu zoomatshini zezinto. Ngokusebenzisa ezi zinzisi, abavelisi bayakwazi ukufumana amandla angcono okuxuba kunye nokunyibilika, kunye nokwanda kokumelana nempembelelo kunye nokuguquguquka. Oku kuvelisa iimveliso ze-PVC ezikumgangatho ophezulu ezinokumelana nobunzima bokusetyenziswa kwemihla ngemihla ngaphandle kokulahlekelwa yimo okanye iimpawu zazo.
Ukongeza kwiingenelo zobugcisa, iziqinisi ze-calcium-zinc nazo zineengenelo zokusingqongileyo. Ngokungafaniyo nezinye iintlobo zeziqinisi zobushushu, ezifana neziqinisi ezisekelwe kwi-lead, iziqinisi ze-calcium zinc azinabungozi kwaye zinobuhlobo nokusingqongileyo. Oku kuzenza zibe lukhetho oluphezulu kubavelisi kunye nabathengi abafuna izixhobo ezizinzileyo nezikhuselekileyo. Ukongeza, ukusetyenziswa kweziqinisi ze-calcium zinc kwimveliso ye-PVC kunceda ukuqinisekisa ukuthotyelwa kwemigaqo nemigangatho yokusingqongileyo, okwenza kube lukhetho olunomtsalane kwiinkampani ezifuna ukunciphisa umkhondo wazo kokusingqongileyo.
Lilonke, iziqinisi ze-calcium zinc zidlala indima ebalulekileyo ekuvelisweni kweemveliso ze-PVC ngokubonelela ngozinzo oluhle kakhulu lobushushu, ukumelana ne-UV kunye neempawu zoomatshini. Ukusetyenziswa kwazo kwimveliso ye-PVC kuvumela ukudalwa kwezinto ezihlala ixesha elide nezihlala ixesha elide ezinokumelana neemeko ezahlukeneyo zokusingqongileyo kunye neemeko zokusetyenziswa. Njengoko imfuno yezinto ezisemgangathweni ophezulu nezizinzileyo iqhubeka ikhula, ukubaluleka kweziqinisi ze-calcium-zinc kwimveliso ye-PVC kusenokwenzeka ukuba kwande, nto leyo eyenza ukuba ibe yinxalenye ebalulekileyo yeshishini leplastiki.
