Zinc ingot (purified metallic zinc)
Zinc ingot refers to pure zinc, of course there will be
impurities, but as zinc ingot, at least more than 90% purity.
Zinc ingot
uses: mainly used in die casting alloy, battery industry,
printing and dyeing industry, medicine, rubber industry,
chemical
industry, zinc and other metal alloys in electroplating, spraying
and other industries have been widely used.
Chinese name zinc ingot
Foreign name BangHua Xin
Other nock - Zinc, 0# zinc, 1# zinc, 2# zinc
Class don't zinc
Chemical formula with recent
The molecular weight of 65
The main application
Physical specifications and packaging
The zinc ingot is rectangular trapezoid, the size is
406+15mm×205+10mm×10mm, the net weight of each piece is
20kg~25kg, the
package is made of galvanized cold-rolled steel belt, 46 pieces
per bundle, the net weight is 920kg~1150kg.
The main features
Zinc can react with acids, bases and salts to form new salts. Its
surface reacts with oxygen, carbon dioxide and water in the air
to produce dense basic zinc carbonate, which protects the product
from oxidation inside.
The dissolution point of zinc is 419.5℃, the boiling point is
907℃, and the density at 0℃ is 7.13g/cm3. Zinc is brittle at
room
temperature and can be pressed into thin sheet or drawn into wire
when heated to 100℃~150℃, but it loses its ductility when the
temperature exceeds 250℃.
Transport, storage, use
It is forbidden to use acid, alkali, salt and other corroded zinc
ingot packaging and transport vehicles to ship, and should be
stored in dry, ventilated, no attached materials in the
warehouse, strictly prevent rain wet.
The melting temperature of zinc should not exceed 500℃ to reduce
oxidative burn loss and volatilization loss. When melting, it is
not suitable to contact with iron and other harmful metals to
avoid contaminating products. Zinc oxide will be produced on the
surface of zinc liquid when melting, and ammonium oxide can be
used to make slag to improve the utilization rate of
zinc.
If zinc ingot products have been wet, before adding molten
liquid, should be dried, so as to avoid "shooting" wounding and
damage equipment.
