Zokhazikika za Lead Compound
Chokhazikika cha lead chimagwiritsidwa ntchito kwambiri m'mafakitale, makamaka chifukwa cha kukhazikika kwawo kwapadera kwa kutentha - chinthu chofunikira kwambiri chomwe chimawapangitsa kukhala ofunikira kwambiri pakukonza ma polima enaake, makamaka popanga zinthu za PVC zolimba zosawoneka bwino (Polyvinyl Chloride) komwe ubwino waukuluwu wawonetsedwa mokwanira. Kupatula kukhazikika kwa kutentha kwapamwamba kumeneku, mchere wa lead umakhalanso ndi kukana kwabwino kwa nyengo, umagwirizana bwino ndi ma resin a PVC, komanso umawononga ndalama zambiri.
| Giredi | Kugwiritsa ntchito | Ndemanga |
| TP-01 | S-PVC | Mbiri ya PVC, kukhazikika bwino |
| TP-02 | S-PVC | Mawaya ndi zingwe za PVC, kukhazikika bwino kwambiri |
| TP-03 | S-PVC | Mapaipi a UPVC, magwiridwe antchito apamwamba |
| TP-04 | S-PVC | Mapaipi a CPVC, magwiridwe antchito apamwamba |
| TP-05 | S-PVC | Bodi ya PVC, yokhazikika bwino |
| TP-06 | S-PVC | Mapaipi a UPVC, ntchito yonse |
Pomanga, cholimbitsa mphamvu ya lead chimagwiritsidwa ntchito kwambiri m'mapaipi a PVC, zolumikizira, ma profiles a zitseko/mawindo, ndi mapepala. Zogulitsazi zimakhala ndi mphamvu zambiri zamakaniko, kukana dzimbiri, komanso nthawi yayitali yogwira ntchito, zoyenera kuperekedwa madzi, ngalande, ndi machitidwe a zimbudzi. Ma profiles a zitseko/mawindo, omwe amafunika kukhazikika muyeso motsutsana ndi kusintha kwa kutentha kwakunja, amadalira mchere wa lead kuti apitirize kugwira ntchito bwino padzuwa la nthawi yayitali komanso kusinthasintha kwa kutentha.
Mu makampani opanga magetsi, mchere wa lead umalimbitsa zinthu zolimba za PVC monga zingwe zolumikizira mawaya, mabokosi amagetsi, ndi ma switch housings. Zimapirira kutentha kwambiri panthawi yokonza ndi kugwiritsa ntchito, kuonetsetsa kuti palibe kuwonongeka kapena kusinthika, motero zimateteza kutenthetsa magetsi komanso chitetezo cha kapangidwe kake.
Chochititsa chidwi n'chakuti, zotsatira za zinthu zolimbitsa thupi zomwe zimateteza ku zinthu zowononga zachilengedwe komanso thanzi la anthu zapangitsa kuti pakhale malamulo okhwima m'madera osiyanasiyana. Komabe, pozisamalira bwino, sizingasinthidwe m'malo moika patsogolo kugwiritsa ntchito bwino ndalama komanso kukhazikika kwa kutentha. Kafukufuku wokhudza njira zina zopanda lead zomwe zimagwirizana ndi kukhazikika kwa kutentha kwawo ukupitirira, cholinga chake ndi kugwirizanitsa magwiridwe antchito, mtengo, ndi chitetezo cha chilengedwe.
Kukula kwa Ntchito
