Makhalidwe a calcium zinc stabilizers ogwirizana ndi chilengedwe:
Calcium zinc stabilizers ndi nitric oxide synthases wopangidwa ndi calcium zinc organic salt, hypophosphite esters, polyether polyols, antioxidants, ndi organic solvents. Ma Calcium zinc stabilizers amalumikizana bwino ndi epoxy resins ndi thickeners, kuwonekera bwino, ndipo sizosavuta kugwa. Amagwiritsidwa ntchito pang'ono ndipo ndi osavuta kugwiritsa ntchito. Komabe, ali ndi vuto la kunyowa kofooka, kuchepetsa kufewetsa kwa mankhwalawa, ndipo kusungidwa kwa nthawi yayitali kungayambitse nkhungu kukula. Solid state composite calcium zinc soap stabilizers amapangidwa makamaka ndi sopo wa polyether, wotsatiridwa ndi sopo wa lauric acid ndi sopo wamafuta acid. Makhalidwe a calcium zinc stabilizers ndi kunyowetsa bwino, zomwe sizichepetsa kufewetsa kwa zinthu zolimba za PVC, ndipo ndizoyenera kupanga ndi kukonza mapaipi olimba a PVC ndi mbiri ya PVC. Zopangidwa ndi kukonzedwa kuchokera kuukadaulo wa microemulsion zimatha kuthetsa zolakwika zomwe tatchulazi.
Timayang'ana kwambiri pazigawo ziwiri kuti tikwaniritse bwino: kuti tisinthe utoto woyambirira, sopo wokwanira wa zinki amawonjezeredwa, ndipo ma antioxidants amagwiritsidwa ntchito popanga zinc chloride, yomwe imakhala chigawo chachikulu cha zinc ndikuchepetsa kuchuluka kwake. sopo wa zinc wowonjezeredwa kuti athetse kuyaka kwa zinc.
Kugwiritsiridwa ntchito kwa zotetezera kusintha kusintha kwa mitundu yapitayi kumabweretsa kusakaniza kwa zinc otsika, komwe kumagwiritsidwa ntchito kwambiri osati pazinthu zofewa komanso kukhazikika kwa kutentha ndi kumveka bwino kwa calcium zinc stabilizers. Zagwiritsidwanso ntchito bwino popanga ndi kukonza zinthu zolimba, kuti zisungidwe bwino kasamalidwe ka calcium / zinc ndikupewa kukongoletsa koyambirira ndi kupondereza kuyaka kwa zinc.
Nthawi zambiri, mchere wamchere umangomangiriridwa pamwamba pa particles za PVC, ndipo zotsatira zake zimakhala zofanana ndi kutsekereza kumangirira pakati pa PVC particles, kuchedwetsa kwambiri plasticization, kuchepetsa mikangano pakati pa PVC particles, ndi kuchepetsa kudula mkati mwa PVC. Zida zopangira zimanyamula katundu wochepa, ndipo kuchuluka kwa mchere wogwiritsidwa ntchito ndi wochuluka. Kuchulukirachulukira kwa tinthu ta mchere wa mtovu kumapangitsanso mphamvu yachiwiri. Zogulitsa zachikhalidwe zobiriwira komanso zachilengedwe monga calcium zinc stabilizers zimakhala ndi mphamvu yamagetsi pakupanga pulasitiki. Magulu ogwirira ntchito optically ali ndi vuto linalake lokhala ndi ma subacute kugwirizana kwa PVC epoxy resin, kupanga chomangira chokhala ndi mphamvu zomangira zolimba kwambiri, zomwe zimafooketsa kapena kuchotsa kukopa kwa ma ion bond m'magulu osiyanasiyana a PVC. Uwu ndiye unyolo wotsegulira wa PVC womwe umalumikizidwa wina ndi mzake, kupangitsa kuti kukhale kosavuta kufalikira kwakunja. Mapangidwe a maselo amagulu ogwira ntchito amapangitsa kuti PVC ifalikire mosavuta. Malire apakati amathandizira kupangidwa kwa PVC epoxy resin.
