Applications: Zinc alloy is mainly used for hydrometallurgy, chemical industry, metallurgy, dyes, electroplating, alloy, die casting and other industries, such as electrolytic zinc, sodium hydrosulfite, lithopone, carved white block, zinc carbonate, zinc sulfate, chloride of zinc, dye intermediates in the production process used as the main reducing agent.

Alloys of zinc powder

Basic properties:
Molecular formula: Zn Molecular weight: 65.38
Physical Properties:
Zinc is the metal zinc powder. Color is dark gray. Spherical molecular structure, the proportion of 7.14 g/cm3, melting point 419º C, boiling point 907 º C,

Chemical properties:
1, zinc do not dissolve in water, soluble in acid and alkali, ammonia.
2, has a strong reduction of zinc, and acid-base effect of hydrogen release.
3, zinc powder burn easily occur, an explosion. Occurred in the hot blue flame burning in air to produce zinc oxide.
Stability in dry air, a large number of zinc in humid air combustion can occur;
Flying in the air, the case of Mars can cause an explosion in the air to allow the concentration of 15mg/m3.
4, zinc powder agglomeration become wet, moist air generated in the basic carbonate and white cover on the surface.
5, high-purity zinc powder and sulfuric acid, nitric acid slowly, when the small amount of other metals such as copper, tin, lead the response speed.
Executive Standard: HHXPQB-XF (HJ) -2005
Physical indicators: % (m / m)

Packaging, transportation, storage:
Packing with iron, rubber or composite plastic woven bag barrel form, each net weight 50kg, with double lined high density polyethylene bags do. Bag with a rope fastened removable tops should be securely and sealed.

Special Reminder:
1, zinc powder with water burning are two items. IMDG Code 52004. Should be covered during transport properties, anti-rain, moisture, fire, loading and unloading should pay attention to light up, to avoid the crash and fall.
2, should be stored in dry, ventilated warehouse fire, and acid, alkali, oxidizer, flammable substances kept separate to avoid open storage. Use of iron, rubber drum storage period of 6 months, the composite plastic woven bag of the storage period of 2 months. Are from the date of production.
