Kodi zinthu zoteteza calcium zinc zomwe siziwononga chilengedwe zimakhala ndi makhalidwe otani?

Zokhazikika za calcium zinc ndi ma synthases a nitric oxide opangidwa ndi mchere wa calcium zinc organic, ma hypophosphite esters, ma polyether polyols, ma antioxidants, ndi ma organic solvents. Zokhazikika za calcium zinc zimagwirizana bwino ndi ma epoxy resins ndi ma thickeners, zowonekera bwino, ndipo sizosavuta kuzimitsa. Zimagwiritsidwa ntchito pang'ono ndipo ndizosavuta kugwiritsa ntchito. Komabe, zili ndi vuto la kunyowa pang'ono, kuchepetsa malo ofewa a chinthucho, ndipo kusungidwa kwa nthawi yayitali kungayambitse kukula kwa nkhungu. Zokhazikika za sopo wa calcium zinc zomwe zimapangidwa makamaka ndi sopo wa polyether, kutsatiridwa ndi sopo wa lauric acid ndi sopo wamafuta acid. Khalidwe la zokhazikika za calcium zinc ndi kunyowa bwino, komwe sikuchepetsa malo ofewa a zinthu zolimba za PVC, ndipo ndikoyenera kupanga ndi kukonza mapaipi olimba a PVC ndi ma profiles a PVC. Zinthu zopangidwa ndi kukonzedwa kuchokera ku ukadaulo wa microemulsion zimatha kuchotsa zolakwika zomwe zatchulidwazi.

Timayang'ana kwambiri mbali ziwiri kuti tiwongolere: kuti tiwongolere utoto pachiyambi, sopo wokwanira wa zinc umawonjezedwa, ndipo ma antioxidants amagwiritsidwa ntchito pochiza zinc chloride, yomwe imakhala zinc yambiri ndipo imachepetsa kuchuluka kwa sopo wa zinc womwe umawonjezedwa kuti uchepetse kutentha kwa zinc.

Kugwiritsa ntchito mankhwala osungira zinthu kuti asinthe utoto wakale kumapangitsa kuti pakhale kuphatikiza kochepa kwa zinc, komwe kumagwiritsidwa ntchito kwambiri osati pazinthu zofewa zokha komanso pakusintha kutentha ndi kumveka bwino kwa zinthu zokhazikika za calcium zinc. Kwagwiritsidwanso ntchito bwino popanga ndi kukonza zinthu zolimba, kuti zisunge bwino njira yoyendetsera calcium/zinc pomwe zikuletsa utoto woyambirira ndikuletsa kuyaka kwa zinc.

Kawirikawiri, mchere wa lead umangolumikizidwa pamwamba pa tinthu ta PVC, ndipo zotsatira zake zimakhala zofanana ndi kutseka kulumikizana pakati pa tinthu ta PVC, kuchedwetsa kwambiri kupangidwa kwa pulasitiki, kuchepetsa kukangana pakati pa tinthu ta PVC, ndikuchepetsa mphamvu yodula mkati mwa PVC. Zipangizo zopangira zimakhala ndi katundu wochepa, ndipo kuchuluka kwa mchere wa lead womwe umagwiritsidwa ntchito kumakhala kokwera. Tinthu ta mchere wa lead tikachuluka, zotsatira zake zimakhala zazikulu kwambiri. Zinthu zobiriwira komanso zachilengedwe monga calcium zinc stabilizers zimakhala ndi mphamvu yamagetsi yolimba panthawi ya pulasitiki. Magulu ogwira ntchito omwe amagwira ntchito bwino amakhala ndi mphamvu yolumikizirana ndi ma subacute a PVC epoxy resin, zomwe zimapangitsa kuti pakhale mgwirizano wamphamvu kwambiri, womwe umafooketsa kapena kuchotsa kukopa kwa ma ion bond m'magawo osiyanasiyana a PVC. Uwu ndi unyolo wotsegulira wa PVC womwe umalumikizana wina ndi mnzake, zomwe zimapangitsa kuti kufalikira kwakunja kukhale kosavuta. Kapangidwe ka mamolekyulu a magulu ogwira ntchito kumapangitsa kuti PVC ifalikire mosavuta. Malire apakati amathandizira kupangidwa kwa pulasitiki kwa PVC epoxy resin.
