Mhedzisiro yekubatana kwe organic tin uye hupfu hwe calcium zinc stabilizers mu polyvinyl chloride (PVC):
Zvigadzirisi zve tin zveOrganic (thiol methyl tin) imhando yePVC heat stabilizer inoshandiswa zvakanyanya. Zvinoita sezvine acidic hydrogen chloride (HCl) muPVC kuti zvigadzire munyu usingakuvadzi (wakaita setin chloride), nokudaro zvichidzivirira kuungana kweHCl uye kuderedza kuora uye kutsvuka kwezvinhu zvePVC.
Powder calcium zinc stabilizer musanganiswa wecalcium ne zinc salts, inowanzo wedzerwa muchimiro chefine powder kuPVC. Calcium ne zinc ions zvese zvine simba rekugadzirisa PVC. Calcium ions dzinogona kugadzirisa acidic substances inogadzirwa muPVC uye kugadzira stable calcium salt compounds. Zinc ions dzinoita related ne hydrogen peroxide (HCl) muPVC kuti dzigadzire inorganic compounds dzisina njodzi uye dzidzivirire kuunganidzwa kweHCl.
Kana organic tin neupfu hwecalcium zinc stabilizers zvikabatana muPVC, zvinogona kukurudzirana uye kuvandudza kugona kurapa HCl. Organic tin inogona kupa kugona kwekuwedzera kuderedza HCl yakawanda inogadzirwa, nepo powdered calcium zinc stabilizers inogona kupa calcium yakawanda ne zinc ions, zvichidzivirira kuunganidzwa kweHCl. Kuburikidza nemhedzisiro iyi yekubatana, organic tin neupfu hwecalcium zinc stabilizers zvinogona kuwedzera kugadzikana kwekupisa kwezvinhu zvePVC, kuvandudza hupenyu hwazvo hwekushanda uye kugadzikana kwekushanda.
Zvinofanira kucherechedzwa kuti huwandu uye huwandu hwezvinodzivirira organic tin necalcium zinc zvinofanirwa kugadziriswa zvine mwero zvichienderana nezvinodiwa uye nzvimbo yekushandiswa kwezvigadzirwa zvePVC, kuitira kuti zvibudirire zvakanyanya. Panguva imwe chete, zvakakosha kutarisisa nyaya dzekuchengetedza uye nharaunda panguva yekushandisa kudzivirira migumisiro yakaipa pahutano hwevanhu nenharaunda.
