Chokhazikika cha Tin ya Methyl
Methyl Tin Stabilizer ndi imodzi mwa zolimbitsa kutentha. Makhalidwe akuluakulu ndi kugwira ntchito bwino kwambiri, kuwonekera bwino kwambiri, kukana kutentha kwambiri, komanso kukana kuipitsidwa ndi vulcanization. Imagwiritsidwa ntchito makamaka mu filimu yopaka chakudya ndi zinthu zina zowonekera za PVC. Ili ndi choletsa chachikulu cha utoto wa zinthu za PVC panthawi yokonza, kukana bwino kwa UV komanso kukhazikika kwa nthawi yayitali, kusinthasintha kwabwino, kusunga bwino utoto panthawi yokonza, komanso kuwonekera bwino kwa zinthu. Makamaka, kukhazikika kwake kwa photothermal kwafika pamlingo wotsogola padziko lonse lapansi, ndipo imatha kusunga bwino kugwiritsanso ntchito kwachiwiri. Organotin stabilizer imagwiritsidwa ntchito kwambiri mumakampani opanga utomoni wa polyvinyl chloride (PVC), yoyenera kupangira ma calender a PVC, extrusion, blow molding, injection molding ndi njira zina zopangira utomoni, makamaka yoyenera mankhwala, chakudya, mapaipi amadzi akumwa ndi njira zina zopangira PVC. (Cholimbitsa ichi sichiyenera kugwiritsidwa ntchito ndi lead, cadmium ndi zina zolimbitsa.) Zambiri zimachepa.

Cholimbitsa Kutentha Chophatikizana
Zolimbitsa mchere wa lead zili ndi magulu awiri akuluakulu a monomers ndi composites, ndipo zolimbitsa mchere wa lead zimagwiritsidwa ntchito ngati cholimbitsa chachikulu ku China. Cholimbitsa kutentha cha mchere wa lead chophatikizana chimagwiritsa ntchito ukadaulo wa symbiotic reaction kuti chisakanize mchere itatu, mchere iwiri ndi sopo wachitsulo mu reaction system ndi kukula koyambirira kwa tirigu wachilengedwe ndi mafuta osiyanasiyana kuti zitsimikizire kuti cholimbitsa kutentha chifalikira mokwanira mu PVC system, ndipo nthawi yomweyo, chifukwa cha kusakanikirana ndi mafuta kuti apange mawonekedwe a granular, chimapewanso poizoni womwe umabwera chifukwa cha fumbi la lead. Zolimbitsa mchere wa lead wophatikizana zimakhala ndi zolimbitsa kutentha komanso zinthu zolimbitsa mafuta zomwe zimafunikira pokonza ndipo zimatchedwa zolimbitsa kutentha zonse.

Chokhazikika cha Calcium ndi Zinc
Zokhazikika za calcium ndi zinc zimapangidwa pogwiritsa ntchito njira yapadera yopangira mchere wa calcium, mchere wa zinc, mafuta, ma antioxidants, ndi zina zotero monga zigawo zazikulu. Sizingosintha zokhazikika za poizoni monga mchere wa lead ndi cadmium ndi organotins, komanso zimakhala ndi kukhazikika kwa kutentha, kukhazikika kwa kuwala ndi kuwonekera bwino komanso mphamvu ya utoto. Ndi PVC resin processing processing imakhala ndi kufalikira kwabwino, kugwirizana, kusinthasintha kwa processing, kusinthasintha kwakukulu, kutha bwino kwa pamwamba pa chinthucho; Kukhazikika kwa kutentha kwabwino, mtundu woyambira wochepa, palibe mvula; Palibe zitsulo zolemera ndi zigawo zina za poizoni, palibe vulcanization; Nthawi yoyesera ya Congo red ndi yayitali, yokhala ndi insulation yabwino yamagetsi, yopanda zodetsa, yokhala ndi kukana kwa nyengo kogwira ntchito kwambiri; Kugwiritsa ntchito kwakukulu, kugwiritsa ntchito mwamphamvu, mlingo wochepa, magwiridwe antchito ambiri; Pakati pa zinthu zoyera, kuyera kuli bwino kuposa kwa zinthu zofanana. Zambiri zatsika.
