Zinc ingot
| Yam khoom | Zinc ingot |
| Txuj | ASTM, AISI, JIS, ISO, EN, BS, GB, thiab lwm yam. |
| Khoom siv | Zn99.99, Zn99.995 |
| Loj | Zinc ingots muaj cov duab plaub trapezoidal nrog qhov loj ntawm 425 ± 5 220 mm × 55 mm. Txhua qhov hnyav yog li 28 ± 2Kg. Lawv yog bundled nrog galvanized txias dov steel strips. Txhua pob ntawm 46 ingots muaj qhov hnyav ntawm kwv yees li 1300Kg. |
| Daim ntawv thov | Nws yog tsuas yog siv nyob rau hauv tuag casting alloy, roj teeb kev lag luam, luam ntawv thiab dyeing kev lag luam, tshuaj kev lag luam, roj hmab kev lag luam, tshuaj kev lag luam, thiab lwm yam. Alloys ntawm zinc thiab lwm yam hlau tau lug siv nyob rau hauv electroplating, spraying thiab lwm yam lag luam. |

Cov khoom siv:
Lub ntsiab lub cev thiab tshuaj lom neeg cov khoom: lub melting point ntawm zinc yog 419.5 ° C, lub boiling point yog 907 ° C, thiab qhov ceev ntawm 0 ° C yog 7.13g / cm3. Zinc yog nkig ntawm qhov kub thiab txias. Thaum rhuab mus rau 100 ° C mus rau 150 ° C, zinc tuaj yeem nias rau hauv daim hlau nyias lossis kos rau hauv cov hlau hlau, tab sis thaum qhov kub siab tshaj 250 ° C, nws poob ductility.
Zinc tuaj yeem ua rau cov kua qaub, cov hauv paus thiab cov ntsev kom tsim cov ntsev tshiab. Qhov saum npoo cuam tshuam nrog oxygen, carbon dioxide, thiab dej hauv huab cua los tsim cov zinc carbonate tuab, uas tiv thaiv cov khoom los ntawm kev oxidized.
Nws yog txwv tsis pub siv cov khoom ntim thiab thauj khoom nrog cov kua qaub, alkali, ntsev thiab lwm yam corrosive zinc ingots, thiab nws yuav tsum tau muab cia rau hauv qhov chaw qhuav, qhov cua, tsis muaj corrosive warehouse, thiab tiv thaiv los nag. Lub melting kub ntawm zinc yuav tsum tsis txhob ntau tshaj 500 ℃ kom txo oxidation poob thiab volatilization poob. Nws yuav tsum tsis txhob nyob rau hauv kev sib cuag nrog hlau thiab lwm yam hlau tsis zoo thaum melting kom tsis txhob kis cov khoom. Zinc oxide yuav raug tsim nyob rau saum npoo ntawm zinc tov thaum melting. Ammonium chloride tuaj yeem siv los ua slag los txhim kho kev siv cov zinc. Yog tias cov khoom siv zinc ingot tau ntub los ntawm nag, nws yuav tsum tau qhuav ua ntej ntxiv cov kua nplaum, kom tsis txhob "blasting" ua mob rau tib neeg thiab ua rau cov khoom puas.
