Ziziphi iimpawu zokusingqongileyo ze-calcium zinc stabilizers:

I-calcium zinc stabilizers i-nitric oxide synthases eyenziwe nge-calcium zinc organic salts, i-hypophosphite esters, i-polyether polyols, i-antioxidants, kunye ne-solvents eziphilayo. I-calcium zinc stabilizers inokuhambelana kakuhle kunye ne-epoxy resins kunye ne-thickeners, ukukhanya okulungileyo, kwaye akukho lula ukugawula. Zisetyenziswa ngamanani amancinci kwaye zilungele ukusetyenziswa. Nangona kunjalo, banobugwenxa bokumanzisa obuthathaka, ukunciphisa indawo yokuthambisa yemveliso, kunye nokugcinwa kwexesha elide kunokubangela ukukhula kwesikhunta. I-Solid state composite calcium zinc soap stabilizers ikakhulu yenziwe ngesepha yepolyether, ilandelwa yisepha ye-lauric acid kunye nesepha enamafutha acid. Iimpawu ze-calcium zinc stabilizers zilungile ukumanzisa, okunganciphisi indawo yokuthambisa ye-PVC yeemveliso ezinzima, kwaye ifanelekile ukuveliswa kunye nokulungiswa kwemibhobho ye-PVC enzima kunye neeprofayili ze-PVC. Iimveliso eziveliswe kwaye zicutshungulwe kwi-teknoloji ye-microemulsion inokuphelisa iziphene ezikhankanywe ngasentla.

Sigxininise kakhulu kwimiba emibini yokwenza uphuculo: ukwenzela ukuba kuphuculwe umbala kwisigaba sokuqala, isixa esaneleyo sesepha ye-zinc yongezwa, kwaye i-antioxidants isetyenziselwa ukuphatha i-zinc chloride engenabungozi, eyaba yinto ephezulu ye-zinc kwaye inciphisa inani. Isepha ye-zinc eyongezwe ukucinezela ukuvutha kwe-zinc.

Ukusetyenziswa kwezithinteli ukuguqula inkqubo yangaphambili yombala kubangela ukudibanisa kwe-zinc ephantsi, esetyenziswa ngokubanzi kungekhona nje kuphela kwiimveliso ezithambileyo kodwa kunye nokuzinza kwe-thermal kunye nokucaca kwe-calcium zinc stabilizers. Kwakhona isetyenziswe ngempumelelo kwimveliso kunye nokulungiswa kweemveliso ezinzima, ukwenzela ukuba kugcinwe kakuhle inkqubo yokulawula i-calcium / i-zinc ngelixa ukhusela umbala wokuqala kunye nokunyanzeliswa kwe-zinc ukutshisa.

Ngokuqhelekileyo, iityuwa ezikhokelayo zifakwe kuphela kumphezulu weengqungquthela zePVC, kwaye umphumo wazo ulingana nokuthintela ukubopha phakathi kweengqungquthela zePVC, ukulibazisa kakhulu iplastiki, ukunciphisa ukungqubuzana phakathi kweengqungquthela zePVC, kunye nokunciphisa umphumo wokusika ngaphakathi kwePVC. Isixhobo sokuvelisa sinomthwalo ophantsi, yaye umlinganiselo wetyuwa yelothe osetyenziswayo ungaphezulu. Ukuqina kwamasuntswana etyuwa elothe, kokukhona kubaluleke ngakumbi isiphumo sesibini. Iimveliso zemveli eziluhlaza kunye nokusingqongileyo ezifana ne-calcium zinc stabilizers zine-electronegativity eyomeleleyo ngexesha lenkqubo yeplastiki. Amaqela asebenzayo optical asebenzayo ane-infectivity ethile kunye neendawo zokudibanisa ezisezantsi ze-PVC epoxy resin, ukuvelisa ibhondi enamandla kakhulu ebhondi, eyenza buthathaka okanye isuse umtsalane weebhondi ze-ion kwiileya ezahlukeneyo zePVC. Eli likhonkco lokuvula lePVC elidityaniswe kunye, okwenza kube lula ukusasazwa kwangaphandle. Isakhiwo se-molecular yamaqela asebenzayo senza kube lula ukuba i-PVC isasazeke. Umda ophakathi uququzelela iplastiki ye-PVC epoxy resin.
