Ulwelo lwe-calcium zinc stabilizers, njengohlobo lwezinto ezisebenzayo ezikwaziyo ukucubungula iimveliso ezithambileyo ezahlukeneyo zePVC, zisetyenziswe ngokubanzi kwiibhanti zokuhambisa zePVC, iithoyi zePVC, ifilimu yePVC, iiprofayili ezikhutshiweyo, izihlangu kunye nezinye iimveliso. I-Liquid calcium zinc stabilizers ihambelana nokusingqongileyo kwaye ayinayo ityhefu, ngokuzinza okuhle kakhulu kwe-thermal, ukusabalalisa, ukuchasana kwemozulu kunye neempawu zokulwa nokuguga.
Amacandelo aphambili e-calcium zinc stabilizers aquka: i-organic acid salts ye-calcium kunye ne-zinc, izinyibilikisi kunyeorganic ezincedisayo ubushushu stabilizers.
Emva kokusetyenziswa kwekhalsiyam kunye ne-zinc organic acid salts, eyona ndlela ingundoqo yokuzinzisa yimpembelelo ye-synergistic ye-calcium kunye ne-zinc organic acid salts. Ezi zinki zetyuwa zithande ukuvelisa i-Lewis acid metal chlorides i-ZnCl2 xa ifunxa iHCl. I-ZnCl2 inefuthe elinamandla e-catalytic ekuthotyweni kwePVC, ngoko ikhuthaza ukuchithwa kwe-PVC, okukhokelela ekuthotyweni kwePVC ngexesha elifutshane. Emva kokudityaniswa, i-catalytic effect ye-ZnCl2 ekuthotyweni kwe-PVC iyanqandwa ngokuphendula ukutshintshwa phakathi kwetyuwa ye-calcium kunye ne-ZnCl2, enokuthi ithintele ngokufanelekileyo ukutshiswa kwe-zinc, iqinisekise ukusebenza kakuhle kwangaphambili kombala kunye nokuphucula ukuzinza kwe-PVC.
Ukongeza kwisiphumo esiqhelekileyo se-synergistic esikhankanywe ngasentla, isiphumo se-synergistic ye-organic axiliary stabilizers kunye nezizinzisi eziphambili kufuneka ziqwalaselwe xa kuphuhliswa i-calcium zinc stabilizers yolwelo, ekwayingqwalasela yophando kunye nophuhliso lwezinzinzi ze-calcium zinc.
