Zitsulo Zopangidwa ndi Zinc Alloy Zipangizo Zopangira Zinthu Zopangidwa ndi Electroplating & Spraying Kuchokera kwa Wopanga

Zinki zophikidwa ndi ufa ndi zinki zophikidwa ndi zinki zomwe zimagwiritsidwa ntchito popanga ufa. Zili ndi zinki zokhala ndi zinthu zina monga aluminiyamu, mkuwa, ndi magnesium. Zimapereka ubwino wambiri, kuphatikizapo malo osungunuka pang'ono, kusinthasintha kwabwino, kulondola kwakukulu, kutha bwino kwa pamwamba, komanso mtengo wochepa, zomwe zimapangitsa kuti zikhale chimodzi mwa zinthu zomwe zimagwiritsidwa ntchito kwambiri padziko lonse lapansi popanga ufa.
I. Kapangidwe ka Core ndi Magiredi Aakulu
Miyezo: GB/T 8738-2014 (Zinc Alloy Ingots for Casting), GB/T 13818-2024 (Zinc Alloys for Die Casting); padziko lonse lapansi, mndandanda wa Zamak (3/5/7) ndi ZA (8/12/27) ndi omwe amagwiritsidwa ntchito kwambiri.
Zamak 3 (Zinc Alloy Nambala 3, Yogwiritsidwa Ntchito Kwambiri)
Kapangidwe kake: Al 3.8%–4.3%, Cu ≤0.03%, Mg 0.035%–0.06%, Zn balance; zonyansa Pb/Cd ≤0.003%, Sn ≤0.001%.
Makhalidwe ake: Kuyenda bwino kwambiri, kukhazikika kwa mawonekedwe ake, komanso kusavuta kugwiritsa ntchito ma electroplating; magwiridwe antchito abwino; ndi oposa 70% ya zomwe zimagwiritsidwa ntchito padziko lonse lapansi.
Kugwiritsa Ntchito: Zoseweretsa, zodzikongoletsera, zokokera zipper, zida zazing'ono, ndi zotchingira zamagetsi.
Zamak 5 (Zinc Alloy Nambala 5, Mphamvu Yaikulu)
Kapangidwe kake: Al 3.8%–4.3%, Cu 0.7%–1.1%, Mg 0.035%–0.06%, Zn balance.
Makhalidwe: Mphamvu ndi kuuma kwakukulu kuposa Nambala 3, kukana kuvala bwino, kukhazikika pang'ono.
Kugwiritsa Ntchito: Maloko a Zitseko zamagalimoto, zipewa za thanki yamafuta, zida zamagetsi, zida zapamwamba.
Zamak 7 (Zinc Alloy Nambala 7, Ubwino Wapamwamba)
Kapangidwe kake: Al 3.8%–4.3%, Cu ≤0.03%, Mg 0.02%–0.04%, trace Ni, kuyera kwambiri.
Makhalidwe: Kugwira ntchito bwino, kutha pamwamba kwambiri, koyenera kukongoletsa bwino.
Kugwiritsa Ntchito: Zodzikongoletsera, mawotchi, zida zapamwamba zokongoletsera, zida zowunikira.
