Kodi njira yokhazikitsira ya madzi a calcium zinc stabilizer ndi chiyani?

Zokhazikika zamadzimadzi za calcium zinc, monga mtundu wa zipangizo zogwirira ntchito zomwe zimatha kukonza zinthu zosiyanasiyana zofewa za PVC, zakhala zikugwiritsidwa ntchito kwambiri mu malamba otumizira a PVC, zoseweretsa za PVC, filimu ya PVC, ma profiles otulutsidwa, nsapato ndi zinthu zina. Zokhazikika zamadzimadzi za calcium zinc ndizochezeka komanso sizowononga chilengedwe, zokhala ndi kukhazikika kwa kutentha, kufalikira, kukana nyengo komanso mphamvu zoletsa ukalamba.

Zigawo zazikulu za zinki zokhazikika za calcium ndi zinc ndi izi: mchere wa organic acid wa calcium ndi zinc, zosungunulira ndizolimbitsa kutentha zothandizira zachilengedwe.

Pambuyo pogwiritsira ntchito mchere wa calcium ndi zinc organic acid, njira yayikulu yokhazikitsira bata ndi mphamvu ya calcium ndi zinc organic acid salts. Mchere wa zinc uwu umakonda kupanga Lewis acid metal chlorides ZnCl2 ikalowa mu HCl. ZnCl2 imakhala ndi mphamvu yamphamvu yochepetsera kuwononga kwa PVC, motero imalimbikitsa kuchotsedwa kwa chlorine mu PVC, zomwe zimapangitsa kuti PVC iwonongeke mwachangu. Pambuyo posakanikirana, mphamvu ya ZnCl2 yochepetsera kuwononga kwa PVC imachepetsedwa kudzera mu kusinthana pakati pa mchere wa calcium ndi ZnCl2, zomwe zimatha kuletsa kutentha kwa zinc, kuonetsetsa kuti utoto umayamba bwino komanso kukulitsa kukhazikika kwa PVC.

Kuwonjezera pa mphamvu yonse yogwirizana yomwe yatchulidwa pamwambapa, mphamvu yogwirizana ya zolimbitsa kutentha zothandizira zachilengedwe ndi zolimbitsa thupi zoyambirira ziyeneranso kuganiziridwa popanga zolimbitsa thupi zamadzimadzi za calcium zinc, zomwe ndi cholinga cha kafukufuku ndi chitukuko cha zolimbitsa thupi zamadzimadzi za calcium zinc.
