Isiphumo sokusebenzisana kwe-organic tin kunye ne-powder calcium zinc stabilizers kwi-polyvinyl chloride (PVC):
Iziqinisi ze-organic tin (thiol methyl tin) luhlobo olusetyenziswa kakhulu lwe-PVC heat stabilizer. Zisabela kunye ne-acidic hydrogen chloride (HCl) kwi-PVC ukuze zenze iityuwa ezingenabungozi (ezifana ne-tin chloride), ngaloo ndlela zithintela ukuqokelelwa kwe-HCl kwaye zinciphise ukubola kunye nokutyheli kwezinto ze-PVC.
I-powder calcium zinc stabilizer ngumxube we-calcium kunye ne-zinc salts, edla ngokudityaniswa ngendlela ye-fine powder kwi-PVC. Zombini i-calcium kunye ne-zinc ions zinamandla okuqinisa i-PVC. I-calcium ions zinokuphelisa izinto ezine-acidic eziveliswa kwi-PVC kwaye zenze ii-stable calcium salt compounds. I-zinc ions zisabela kwi-hydrogen peroxide (HCl) kwi-PVC ukuze zenze ii-inorganic compounds ezingenabungozi kwaye zithintele ukuqokelelana kwe-HCl.
Xa iziqinisi ze-organic tin kunye ne-powder calcium zinc stabilizers zisebenza kunye kwi-PVC, zinokukhuthazana kwaye ziphucule amandla okunyanga i-HCl. I-Organic tin inokubonelela ngamandla ongezelelweyo okuthomalalisa ukonakala kwe-HCl eveliswayo, ngelixa iziqinisi ze-calcium zinc eziphuhliweyo zinokubonelela nge-calcium kunye ne-zinc ions ezingaphezulu, nto leyo ethintela ngakumbi ukuqokelelwa kwe-HCl. Ngale mpembelelo yokusebenzisana, iziqinisi ze-organic tin kunye ne-powder calcium zinc zinokuphucula uzinzo lobushushu bezinto ze-PVC, ziphucule ubomi bazo benkonzo kunye nokuzinza kokusebenza.
Kufuneka kuqatshelwe ukuba ubungakanani kunye nomlinganiselo we-organic tin kunye ne-calcium zinc stabilizers kufuneka zilungiswe ngokufanelekileyo ngokweemfuno ezithile kunye nendawo yokusetyenziswa kweemveliso ze-PVC, ukuze kufezekiswe isiphumo esihle kakhulu sokusebenzisana. Kwangaxeshanye, kuyimfuneko ukuqaphela imiba yokhuseleko kunye neyokusingqongileyo ngexesha lokusetyenziswa ukuze kuthintelwe iziphumo ezimbi kwimpilo yabantu nakwindalo esingqongileyo.
