Kugwiritsa ntchito PVC lead salt stabilizer

Chokhazikika cha mchere wa PVC ndi chokhazikika cha kutentha chomwe chimagwiritsidwa ntchito kwambiri pokonza polyvinyl chloride (PVC). Chimathandizira kwambiri kukhazikika kwa kutentha kwa zinthuzo pogwira hydrogen chloride (HCl), ndipo chili ndi kutchinjiriza kwamagetsi kwabwino kwambiri komanso ubwino wake. Magawo ofunikira omwe amagwiritsidwa ntchito ndi awa:
Zochitika zazikulu zogwiritsira ntchito:
1. Zinthu zolimba za PVC
Monga mapaipi, mbale, ma profiles, ndi zina zotero, makamaka zoyenera zinthu zosawoneka bwino (monga zingwe ndi zingwe zomangira, mapaipi omangira madzi). Zolimbitsa mchere wa lead zimatha kuletsa kuwonongeka kwa kutentha kwa PVC panthawi yokonza ndikuwonjezera moyo wa ntchito ya zinthu.
2. Makampani opanga mawaya ndi zingwe
Chifukwa cha mphamvu zake zabwino kwambiri zotetezera magetsi, zoteteza mchere wa lead zimagwiritsidwa ntchito kwambiri popanga zipangizo za PVC.
Ubwino waukadaulo:
Kukonza mchere wa lead wopangidwa ndi zinthu zosiyanasiyana: Mchere wa lead umaphatikizidwa ndi mafuta odzola pogwiritsa ntchito ukadaulo wa symbiotic reaction kuti apange zinthu zopanda fumbi, kuchepetsa kuipitsa fumbi komanso kukonza kufalikira kwa fumbi.
Kugwiritsa ntchito bwino ndalama: Chitsulo chochuluka, mphamvu yotha kuyamwa HCl, komanso kusinthasintha kwa kutentha, koyenera kupanga mafakitale akuluakulu.
Zolepheretsa ndi Njira Zina Zochitira Zinthu
Vuto la poizoni: Kuopsa kwa lead chifukwa cha zitsulo zolemera kumalepheretsa kugwiritsidwa ntchito kwake muzinthu zokhudzana ndi chakudya, zida zamankhwala, ndi zina.
Kusintha chilengedwe: Chifukwa cha kufunikira kwakukulu kwa chitetezo cha chilengedwe, zinthu zochepetsa poizoni monga calcium zinc composite stabilizers ndi organotin pang'onopang'ono zikulowa m'malo mwa mchere wa lead.
Chidule: Zosungira mchere wa PVC zomwe zimathandizira kuti zinthu zisamawonongeke m'mafakitale akadali ndi mpikisano m'mafakitale akale, koma kuchuluka kwa momwe zimagwiritsidwira ntchito kuyenera kulinganizidwa ndi malamulo okhudza chilengedwe. Ukadaulo wa mchere wamitundu yosiyanasiyana wasunga malo ake pamsika m'njira zinazake mwa kukonza njira ndi njira.
