Zinc indot
| Chinthu | Zinc indot |
| Wofanana | ASTM, Aisi, Jis, ISO, AYE, BS, GS, etc. |
| Malaya | Zn99.99, ZN99.995 |
| Kukula | Zizindikiro za zinc amakhala ndi mawonekedwe a trapengodal ndi kukula kwa 425 ± 5 220 mm × 55 mm. Kulemera kulikonse ndi pafupifupi 28 ± 2kg. Amakhala ophatikizidwa ndi zitsulo zozizira kwambiri. Mtolo uliwonse wa mitolo 46 ili ndi kulemera kwa intaneti pafupifupi 1300kg. |
| Karata yanchito | Amagwiritsidwa ntchito makamaka pakupha alloy, kusindikiza kwa batri, kugwiritsa ntchito ndi kupatsirana makampani ogulitsa, kugulitsa mabizinesi, etc. |

Katundu:
Mankhwala akulu ndi mankhwala: malo osungunuka a zinki ndi 419.5 ° C, pomwepo ndi 907 ° C, ndi kachulukidwe ku 0 ° Zinc ndi yopanda kutentha. Atatchera mpaka 100 ° C mpaka 150 ° C, zinc amatha kukanikizidwa ndi ma waya owonda kapena kukokedwa m'mawere ambiri, koma kutentha kwa matenthedwe 250 C, kumataya kutsirira.
Zinc amatha kuchitira ndi acid, zodetsa ndi mchere kuti mupange mchere watsopano. Nthaka imalumikizana ndi okosijeni, kaboni dayokisi, ndi madzi mlengalenga kuti apange zowonjezera za carbonate, zomwe zimateteza malonda.
Ndi zoletsedwa kugwiritsa ntchito zida zonyamula ndi zoyendera ndi acid, alkali, mchere ndi zina zachilengedwe, ndipo ziyenera kusungidwa m'malo ogulitsira, opanda kanthu, komanso otetezedwa ku mvula. Kutentha kwamphamvu kwa zinzi sikuyenera kupitirira 500 ℃ kuti muchepetse kutaya kwa oxidation ndi kutayika kwa mawu. Siziyenera kulumikizana ndi chitsulo ndi zitsulo zina zovulaza mukasungunuka kuti zisadetsedwe. Zirc oxide imapangidwa pamwamba pa yankho la zinc nthawi yosungunuka. Amonium chloride akhoza kugwiritsidwa ntchito kuti asunge zosintha kugwiritsa ntchito zinc. Ngati zowonongeka za zinc itatu zakhala zonyowa musanawonjezere madzi osungunula, kuti mupewe "kufuula" kupweteketsa anthu ndikuwononga zida.
