Die Cast Metal Zinc Alloy Ingots Raw Materials neElectroplating & Spraying Painting zvakananga kubva kuMugadziri

Zvidimbu zvezinc zvinogadzirwa nesimbi zvinoshandiswa pakukanda zvinhu. Zvidimbu zvine zvinhu zvakaita sealuminium, copper, uye magnesium. Zvinopa musanganiswa wezvakanakira, zvinosanganisira kunyunguduka kushoma, kuyerera kwakanaka, kurongeka kwepamusoro-soro, kupenya kwakatsetseka, uye mutengo uri pakati nepakati, zvichiita kuti zvive chimwe chezvinhu zvinoshandiswa zvakanyanya pasi rose pakukanda zvinhu nesimbi.
I. Kuumbwa Kwepakati uye Magiredhi Makuru
Maitiro: GB/T 8738-2014 (Zinc Alloy Ingots for Casting), GB/T 13818-2024 (Zinc Alloys for Die Casting); pasi rose, Zamak (3/5/7) uye ZA (8/12/27) nhevedzano dzinoshandiswa zvakanyanya.
Zamak 3 (Zinc Alloy Nhamba 3, Inonyanya Kushandiswa)
Musanganiswa: Al 3.8%–4.3%, Cu ≤0.03%, Mg 0.035%–0.06%, Zn yakaenzana; tsvina Pb/Cd ≤0.003%, Sn ≤0.001%.
Hunhu: Kufamba zvakanaka kwazvo, kugadzikana kwezvikamu, uye nyore kushandisa electroplating; kushanda zvakanaka; inodarika 70% yekushandiswa kwepasi rose.
Mashandisirwo: Matoyi, zvishongo, madhonza emazipi, midziyo midiki, uye mavharo emagetsi.
Zamak 5 (Zinc Alloy Nhamba 5, Simba Rakanyanya)
Kuumbwa: Al 3.8%–4.3%, Cu 0.7%–1.1%, Mg 0.035%–0.06%, Zn yakaenzana.
Hunhu: Simba rakakwirira uye kuomarara kupfuura Nhamba 3, kuramba kupfeka zvakanaka, kugadzikana kwakaderera zvishoma.
Mashandisirwo: Makiyi emasuo emotokari, zvivharo zvetangi remafuta, zvikamu zvemagetsi, dzimba dzematurusi, midziyo yepamusoro-soro.
Zamak 7 (Zinc Alloy Nhamba 7, Hunhu Hwakakwirira)
Musanganiswa: Al 3.8%–4.3%, Cu ≤0.03%, Mg 0.02%–0.04%, trace Ni, kuchena kwakanyanya.
Hunhu: Kugadzikana kwakanaka, kupedzisa kwepamusoro-soro, kwakakodzera zvikamu zvekushongedza nemazvo.
Mashandisirwo: Zvishongo, mabhokisi ewachi, zvikamu zvekushongedza zvepamusoro-soro, zvikamu zvemaziso.
