Umphumela we-synergistic we-organic tin kanye ne-powder calcium zinc stabilizers ku-polyvinyl chloride (PVC):
Iziqinisi ze-Organic tin (thiol methyl tin) ziwuhlobo oluvame ukusetshenziswa lwe-PVC yokusimamisa ukushisa. Zisabela nge-acidic hydrogen chloride (HCl) ku-PVC ukuze zenze usawoti wezinto ezingaphili ezingenabungozi (njenge-tin chloride), ngaleyo ndlela zivimbele ukunqwabelana kwe-HCl futhi zehlise ukuwohloka nokubaphuzi kwezinto ze-PVC.
I-Powder calcium zinc stabilizer iyingxube kasawoti we-calcium ne-zinc, ngokuvamile engezwa ngendlela yempushana ecolekile ku-PVC. Kokubili i-calcium ne-zinc ion inamandla okuzinzisa i-PVC. I-calcium ions inganciphisa izinto ezine-asidi ezikhiqizwa ku-PVC futhi zakhe izinhlanganisela ezizinzile zikasawoti we-calcium. I-Zinc ions isabela nge-hydrogen peroxide (HCl) ku-PVC ukwenza izinhlanganisela ezingenabungozi ezingenabungozi futhi ivimbele ukunqwabelana kwe-HCl.
Lapho i-organic tin ne-powder calcium zinc stabilizers kuhlangana ku-PVC, zingakhuthazana futhi zithuthukise ikhono lokwelapha i-HCl. I-organic tin inganikeza amandla engeziwe okunciphisa amandla okwehlisa i-HCl eyengeziwe ekhiqizwayo, kuyilapho izinzinzisi ze-calcium zinc eziyimpuphu zinganikeza ama-ion e-calcium ne-zinc engeziwe, kuqhubeke kuvimbele ukunqwabelana kwe-HCl. Ngalo mphumela we-synergistic, i-organic tin ne-powder calcium zinc stabilizers ingathuthukisa ukuzinza okushisayo kwezinto ze-PVC, ithuthukise impilo yabo yesevisi nokuzinza kokusebenza.
Kufanele kuqashelwe ukuthi inani nengxenye ye-organic tin kanye ne-calcium zinc stabilizers idinga ukulungiswa ngokufanele ngokuya ngezidingo ezithile kanye nemvelo yokusetshenziswa kwemikhiqizo ye-PVC, ukuze kuzuzwe umphumela omuhle kakhulu we-synergistic. Ngesikhathi esifanayo, kuyadingeka ukunaka ukuphepha kanye nezindaba zemvelo ngesikhathi sokusetshenziswa ukugwema imiphumela emibi empilweni yabantu kanye nemvelo.
