Ntchito ya PVC lead salt stabilizer

Chokhazikika cha mchere wa PVC ndi chokhazikika cha kutentha chomwe chimagwiritsidwa ntchito kwambiri pokonza polyvinyl chloride (PVC), chomwe chimaletsa kuwonongeka kwa kutentha kwa zinthu mwa kuyamwa hydrogen chloride yomwe imapangidwa ndi kuwonongeka kwa PVC ndikuyika m'malo mwa maatomu osakhazikika a chlorine. Makhalidwe ake ogwiritsira ntchito ndi awa:
Malo ofunikira kwambiri: zinthu zolimba za PVC zosawoneka bwino
Zolimbitsa mchere wa lead zimagwiritsidwa ntchito kwambiri popanga zinthu zolimba komanso zosawoneka bwino za PVC monga mawaya ndi zingwe, mapaipi, ndi ma profiles chifukwa cha mtengo wake wapamwamba komanso kukhazikika bwino kwa kutentha. Choteteza chake chamagetsi ndi chabwino kwambiri, makamaka choyenera malo opangira mafakitale omwe safuna kuwonekera kwambiri.
Ubwino wa zinthu zolimbitsa mchere wa lead: Zinthu zolimbitsa mchere wa lead zomwe zimagwiritsidwa ntchito popanga zinthu zimagwiritsa ntchito ukadaulo wa symbiotic reaction kusungunula mchere wa lead ndi mafuta, kupanga dongosolo lopanda fumbi, kukonza kufalikira kwa madzi ndikuchepetsa kuipitsa fumbi, kukhala njira yopanda fumbi kwa makampani opanga PVC. Mtundu uwu wa chinthu ukhoza kusintha kuyenda kwa zinthu ndi mawonekedwe a chinthucho pokonza mapaipi olimba a PVC, mapepala, ndi zinthu zina.
Zolepheretsa ndi Njira Zina Zochitira Zinthu
Kuchepetsa poizoni: Khalidwe lokhala ndi lead yachitsulo cholemera limapereka malamulo okhwima pa kugwiritsidwa ntchito kwake m'malo omwe ali ndi zofunikira kwambiri paukhondo monga kulongedza chakudya ndi zida zachipatala.
Kusintha chilengedwe: Popeza malamulo okhudza chilengedwe akukakamizidwa (monga momwe China idaletsera kugwiritsa ntchito zinthu zolimbitsa mchere wa lead mu zipangizo zomangira za PVC kuyambira 2012), zinthu zolimbitsa zachilengedwe monga organotin ndi calcium zinc pang'onopang'ono zakhala njira zina.
Kuletsa kwapadera kwa njira: Zolimbitsa mchere wa lead zimatha kusokoneza magwiridwe antchito a zinthu zopangira thovu za ADC, kotero sizoyenera kupanga chikopa chopangidwa ndi PVC chomwe chimafuna kukonza thovu.
Mitundu Yodziwika ndi Mapulogalamu Ophatikizana
Mchere wa monomeric lead: monga trisodium lead sulfate (yokhala ndi kutentha kolimba), dibasic lead phosphite (yokhala ndi ntchito yoteteza ku ma antioxidants), ndi zina zotero.
Dongosolo la zinthu zopangidwa ndi lead: Mitundu 2-3 ya mchere wa lead imagwiritsidwa ntchito kwambiri popanga zinthu zenizeni kuti igwirizane ndi kukhazikika kwa kutentha, magwiridwe antchito, ndi mtengo. Zinthu zokhazikika za zinthu zopangidwa ndi lead zimapitilira kugwiritsidwa ntchito m'magawo ena kudzera mu njira zabwino kwambiri (zomwe zili ndi lead 20% -60%) ndi njira zina.
Kuti mudziwe zambiri, chonde tsatirani BONTECN GROUP CHINA. Tili ndi antchito aluso oti ayankhe mafunso anu.
