Ubwino ndi kuipa kwa zinthu zokhazikika za calcium zinc

Pa nthawi yopangira pulasitiki, zokhazikika za calcium zinc zimakhala ndi mphamvu zambiri zamagetsi, ndipo ma node ozungulira a PVC resin amakhala ndi mphamvu inayake, zomwe zimapangitsa kuti pakhale mphamvu zolimba.
Zokhazikika za calcium zinc zitha kugawidwa m'magulu awiri: zokhazikika za calcium zinc ndi zokhazikika zamadzimadzi za calcium zinc
Chokhazikika cha calcium zinc chamadzimadzi chimagwirizana ndi ma resin ndi ma plasticizer, ndipo chimawoneka bwino, chimakhala ndi mvula yochepa, chimakhala ndi mlingo wochepa, komanso chimagwiritsidwa ntchito mosavuta. Zoyipa zazikulu ndi mafuta ochepa komanso kuwonongeka pakasungidwa kwa nthawi yayitali.
Zolimbitsa calcium zinc zolimba zimapangidwa makamaka ndi sopo wa stearic acid. Chogulitsachi chimadziwika ndi mafuta abwino ndipo ndi choyenera kukonzedwa mapaipi olimba a PVC ndi ma profiles.
Zinthu zomwe zimagwiritsidwa ntchito pogwiritsa ntchito ukadaulo wa microemulsification zimathetsa zovuta zomwe zatchulidwazi. Yang'anani kwambiri pakukonza zinthu kuchokera mbali ziwiri: kusintha mtundu woyamba, kugwiritsa ntchito sopo wokwanira wa zinc, ndikugwiritsa ntchito chinthu chophatikizana kuti zinc chloride ikhale yopanda vuto, yomwe imakhala zinc yambiri; Kuchepetsa kuchuluka kwa sopo wa zinc kuti zipewe kuyaka kwa zinc ndikusintha mtundu woyamba ndi zowonjezera kumadziwika kuti low zinc blending. Sikuti imagwiritsidwa ntchito kwambiri pazinthu zofewa zokha, komanso pokonza zinthu zolimba.
Zokhazikika za calcium zinc, chifukwa cha kuchuluka kwa ma elekitironi, zimakhala ndi mphamvu yogwirizana ndi ma node a PVC resin panthawi yopangidwa ndi pulasitiki, zomwe zimapangitsa kuti mphamvu ya ma bond energy ikhale yofooka kapena kuthetsa kukopa kwa ma ion bond m'magawo osiyanasiyana a PVC. Izi zimapangitsa kuti magawo olumikizana a PVC akhale osavuta kufalikira, ndipo magulu a mamolekyu amakhala ndi malire ang'onoang'ono, zomwe zimathandiza kuti utomoni wa PVC ukhale wopangidwa ndi pulasitiki. Zimayambitsa kuwonjezeka kwakukulu kwa kuthamanga kwa kusungunuka, kusungunuka.
Kukhuthala kwa thupi kumachepa, kutentha kumawonjezeka, ndipo kutentha kwa pulasitiki kumachepa.
Kuphatikiza apo, popeza zida zochizira za PVC zachikhalidwe zimapangidwa kuti zigwiritsidwe ntchito pogwiritsa ntchito zolimbitsa mchere wa lead, ngakhale zitawonjezeredwa mafuta okwanira, sizingalepheretse utomoniwo kupitirira kupangidwa pulasitiki pakapita nthawi yokwanira, zomwe zingasokoneze kulimbitsa mafuta koyambirira. Pakagwiritsidwa ntchito pambuyo pake, kusungunuka kwa PVC kumadya kutentha kwakukulu kokhazikika mu gawo la homogenization, koma nthawi yomweyo sikungathe kukwaniritsa kukhuthala ndi kusinthasintha koyenera kuti kukwaniritse zosowa za PVC yolimba.
