产品描述

Pure zinc ingot refers, of course, there will be impurities, but as zinc, at least more than 90% purity. Zinc uses: mainly used for die-casting alloys, batteries, printing and dyeing industry, pharmaceutical industry, rubber industry, chemical industry, an alloy of zinc and other metals in electroplating, painting and other industries are widely used.Main Application:
(A) galvanized
Zinc has excellent resistance to atmospheric corrosion, it is mainly used for surface coating of steel and steel parts (such as galvanized sheet), widely used in automotive, construction, shipbuilding, light industry and other industries. In recent years, Western countries began to try to do directly with a zinc alloy plate roof covering material, which can be up to life 120--140 years, and then recycled, and galvanized iron roofing material as life generally 5--10 years.
(B) of the copper alloy material (such as brass)
For the automotive and machinery industries. Zinc has suitable mechanical properties. Zinc itself is not high strength and hardness, but after adding alloying elements aluminum, copper, its strength and hardness are greatly improved, especially the emergence of titanium zinc and copper, its mechanical properties close to or reach aluminum, brass , the level of gray cast iron, and its creep resistance is also significantly be improved. Thus, zinc, copper and titanium has been widely used in hardware production.
(C) zinc alloy for casting
Mainly for the casting for the automotive and light industry. Many zinc alloy processing performance are relatively good, pass processing rate of up to 60% -80%. MV excellent performance, deep drawing, and self-lubricating, extending the life of the die, the available brazing or resistance welding or arc welding (required in helium) welding, surface can be plated or coated, cutting performance is good. Under certain conditions, with excellent superplasticity.
In addition, zinc has a good anti-electromagnetic properties. Electrical conductivity of zinc is 29% for electric and copper, in the case of RF interference, zinc plate is a very effective shielding material, and because zinc is non-magnetic, suitable for housing materials and instruments and instrument parts of the coin, Meanwhile, zinc and other metal itself and the collision will not spark, suitable for underground explosion-proof equipment.
(D) for the manufacture of zinc oxide, about 11%
Widely used in rubber, paint, enamel, pharmaceutical, printing, fiber and other industries.
(E) for the manufacture of dry batteries, zinc cake, zinc plate form, accounting for about 13%.
Zinc with appropriate chemical properties. Zinc can occur with NH4CI, release H + cations. Zinc - manganese dioxide zinc batteries is the use of this feature, made with zinc alloy battery case, both the battery electrolyte container, took part in the cell reaction constitutes a battery anode. It's this performance is also widely used in the pharmaceutical industry.
