Kodi ntchito ya calcium zinc stabilizer mu zinthu za PVC ndi yotani?

Chokhazikika cha calcium ndi zinc chimapangidwa ndi njira yapadera yophatikizana ndi mchere wa calcium, zinc, mafuta ndi antioxidant monga zigawo zazikulu. Sichingosintha mchere wa lead ndi cadmium ndi zokhazikika za poizoni monga organotin, komanso chimakhala ndi kukhazikika kwa kutentha, kukhazikika kwa kuwala ndi kuwonekera bwino komanso mphamvu ya utoto. Machitidwe okhazikika a Ca-Zn atsimikizira kuti muzinthu zopangidwa ndi PVC resin, magwiridwe antchito ndi kukhazikika kwa kutentha ndizofanana ndi zomwe zimapangitsa kuti mchere wa lead ukhale wokhazikika, womwe ndi wokhazikika bwino wopanda poizoni.

Maonekedwe a calcium zinc stabilizer makamaka ndi ufa woyera, flake, phala.

Chokhazikika cha zinki cha calcium chimagwiritsidwa ntchito kwambiri pokonza ndi kupanga zinthu za PVC, ndipo zinthu za PVC zomwe zimapangidwa zimakhala ndi zinthu zambiri zabwino kwambiri. Zotsatirazi zikufotokoza ntchito yeniyeni ya zokhazikika za calcium ndi zinki:

1, ikhoza kusintha chokhazikika cha organotin ndi chokhazikika cha mchere wa lead, kuti ikwaniritse zofunikira za waya ndi chingwe zomwe sizili poizoni pa thanzi la chilengedwe;

2, yokhala ndi kuyera koyambirira kwabwino komanso kukhazikika kwa kutentha, kuipitsa kwa anti-sulfide;

3, calcium zinc stabilizer ili ndi mafuta abwino komanso mphamvu yapadera yolumikizira, kotero kuti chodzazacho chimakhala ndi kufalikira kwabwino, chimawonjezera kulongedza kwa utomoni, chimawongolera magwiridwe antchito azinthu, chimachepetsa kuwonongeka kwa makina, ndikuwonjezera moyo wautumiki wa zida;

4, kulimbikitsa ndi kulimbikitsa ntchito yosungunula, kusungunuka kwa pulasitiki ndikwabwino;

5, ingapangitse kuti PVC isakanizike bwino komanso kuti isungunuke mofulumira kwambiri, zomwe zimapangitsa kuti pamwamba pake pakhale posalala.

Zinc stabilizer ndi chinthu choteteza chilengedwe komanso chothandiza kwambiri pa kutentha kwa madzi a calcium zinc. Chokhazikika bwino pa kutentha komanso chowonekera bwino, palibe mvula pamwamba komanso kusamuka kwa zinthu za PVC, komanso chabwino ndi mafuta osatentha, epoxy methyl ester, calcium zinc stabilizer ndi mafuta a epoxy soya. Choyenera kukonzedwa ndi PVC phala, chomwe chimagwiritsidwa ntchito kwambiri mu slush, pulasitiki, pulasitiki ndi ukadaulo wina wopangira PVC.

Calcium zinc stabilizer sikuti imangokhala ndi mphamvu yolamulira kukhuthala komanso kukhuthala, komanso imakhala ndi utoto wabwino komanso kusunga mtundu poyamba.

Katunduyu watsimikizika kuti ndi wothandiza kwambiri pa kutentha. Amagwirizana bwino, sasinthasintha kwambiri, sasinthasintha kwambiri, amakana kuwala bwino, ndi oyenera kugwiritsa ntchito payipi, granulation, rolled film, zoseweretsa, conveyor lamba, nsalu zotsatsa, mapepala ophimba mapepala ndi makampani ena a PVC.
