Description:

Zinc oxide (ZnO), commonly known as zinc white, is a kind of oxide of zinc, which is insoluble in water but soluble in acid and alkali. Zinc oxide(indirect method)  is the use of zinc ingots as raw materials, which is conversed to zinc vapor in graphite crucible at 1000 ° C, then zinc vapor is oxidized by bubbling air and through the cooling tube, zinc oxide particles are collected. The product purity varies with the raw material of zinc ingots. Except zinc ingots, zinc slag is another kind of raw material. Good technology and pure zinc ingots can make the product purity reach more than 99.8%.

Product Advantages:

Applications:

1. Indirect method zinc oxide is used as a reinforcing，active and curing agent in naturalrubber and synthetic rubber, it also used as the coloring agents and fillers in white glue. It can make rubber has good abrasion resistance, tear resistance and elasticity. It can be used in paint, ink, varnished coloring and printing industry.

2.  In the match industry, zinc oxide (indirect method) is applied to neutralize acid of glue and increase the adhesive effect.

3.   In the medical industry, zinc oxide can be used as adhesive material.

4.   In the cosmetics industry, zinc oxide have the ablity to absorb ultraviolet.
