Apperance: white powder. Odorless. 

Nature: The relative density is 5. 606; Melting point 1975 °c; Sublimation at 1720 °c. Stable at room temperature, insoluble in water and alcohol, soluble in acid, alkali ammonia salt solution, amphoteric oxide. Absorption of carbon dioxide and water in the air to produce zinc carbonate white, should be sealed preservation. Not reduced by hydrogen, it is lemon yellow when heated, and turns white after cooling. It has good hiding power and coloring power.

Use: It is used as a pigment for paint and a filler for rubber. It is used in medicine to make ointments, zinc pastes, plasters, etc.Suitable for use as a zinc supplement in feed processing mainly used in rubber or cable industry as a reinforcing agent and active agent, also as a white adhesive colorant and filler, used in chloroprene rubber curing agent Application of raw material gas for fine desulfurization in chemical fertilizer industry Mainly used as white pigment, rubber vulcanization active agent, reinforcing agent, organic synthesis catalyst, desulfurization agent, used in electrostatic copying, pharmaceutical, etc Applications for ammonia synthesis, oil, natural gas, chemical feed gas desulfurization Use as a matrix for analytical reagents, reference reagents, fluorescent agents, and photosensitive materials Applications for electrostatic wet copying, dry transfer, laser fax communications, electronic

Safety: Store in a ventilated, cool, dry warehouse. The package should be tightly sealed to prevent breakage. Protection against heat, water and moisture. And pay attention to the strong acid and edible raw materials Isolation storage. In case of fire, it can be suppressed by using water, foam fire extinguishing equipment or other fire extinguishing equipment.
