Zithini iimpawu zeziqinisi ze-calcium zinc ezinobuhlobo nokusingqongileyo:

Iziqinisi zeCalcium zinc zii-synthases ze-nitric oxide ezakhiwe ziityuwa ze-calcium zinc organic, ii-hypophosphite esters, ii-polyether polyols, ii-antioxidants, kunye nezinyibilikisi ze-organic. Iziqinisi zeCalcium zinc zihambelana kakuhle nee-epoxy resins kunye neziqinisi, zicacile kakuhle, kwaye azilula ukuzilungisa. Zisetyenziswa ngobuninzi obuncinci kwaye kulula ukuzisebenzisa. Nangona kunjalo, zinengxaki yokungakwazi ukumanzisa kakuhle, ukunciphisa indawo yokuthamba kwemveliso, kwaye ukugcinwa ixesha elide kunokubangela ukukhula kwesikhunta. Iziqinisi zeSolid state composite calcium zinc seap zenziwe ikakhulu ngesepha ye-polyether, zilandelwa yisepha ye-lauric acid kunye nesepha ye-fatty acid. Uphawu lweziqinisi zeCalcium zinc kukumanzisa kakuhle, okunganciphisi indawo yokuthamba kweemveliso eziqinileyo zePVC, kwaye zifanelekile kwimveliso kunye nokucutshungulwa kwemibhobho yePVC eqinileyo kunye neeprofayili zePVC. Iimveliso eziveliswe kwaye zicutshungulwe kwitekhnoloji ye-microemulsion zinokususa ezi ziphene zikhankanyiweyo.

Sigxila kakhulu kwiinkalo ezimbini zokwenza uphuculo: ukuze kuphuculwe umbala kwasekuqaleni, kongezwa isixa esaneleyo sesepha ye-zinc, kwaye ii-antioxidants zisetyenziselwa ukunyanga i-zinc chloride engenabungozi, eba yi-zinc compound eninzi kwaye inciphise isixa sesepha ye-zinc eyongeziweyo ukuthintela ukutsha kwe-zinc.

Ukusetyenziswa kwezithinteli zokuthintela ukutshintsha inkqubo yombala yangaphambili kubangela indibaniselwano ephantsi ye-zinc, esetyenziswa kakhulu kungekuphela nje kwiimveliso ezithambileyo kodwa nakwizinzo zobushushu kunye nokucaca kwezithinteli ze-calcium zinc. Ikwasetyenziswe ngempumelelo kwimveliso kunye nokulungiswa kweemveliso eziqinileyo, ukuze kugcinwe ngcono inkqubo yolawulo lwe-calcium/zinc ngelixa kuthintelwa ukutsha kwe-zinc kwangethuba.

Ngokubanzi, iityuwa ze-lead zincamatheliswa kuphela kumphezulu wee-pc particles ze-PVC, kwaye isiphumo sazo silingana nokuthintela ukubopha phakathi kwee-pc particles ze-PVC, ukulibazisa kakhulu ukwenziwa kweplastiki, ukunciphisa ukungqubana phakathi kwee-pc particles, kunye nokunciphisa isiphumo sokusika ngaphakathi kwe-PVC. Izixhobo zemveliso zithwala umthwalo ophantsi, kwaye ubungakanani betyuwa ye-lead esetyenzisiweyo buphezulu. Okukhona ii-pc particles zetyuwa ye-lead zixineneyo, kokukhona isiphumo sesibini sibaluleke ngakumbi. Iimveliso zemveli eziluhlaza nezinobuhlobo nokusingqongileyo ezifana neziqinisi ze-calcium zinc zine-electronegativity enamandla ngexesha lenkqubo yokwenziwa kweplastiki. Amaqela asebenzayo asebenzayo anokusuleleka okuthile ngamanqaku onxibelelwano oluncinci lwe-PVC epoxy resin, evelisa ikhonkco elinamandla amakhulu ebhondi, elibuthathaka okanye elisusa ukutsala kwee-ion bonds kwiileya ezahlukeneyo ze-PVC. Le yikhonkco yokuvula ye-PVC edityaniswe kunye, okwenza kube lula ukusasazwa kwangaphandle. Ulwakhiwo lwe-molecular lwamaqela asebenzayo lwenza kube lula ukuba i-PVC isasazeke. Umda ophakathi unceda ukwenziwa kwe-PVC epoxy resin ibe yiplastiki.
