Product Name:Chemical grade zinc oxide
Usage: Widely used in production of zinc compound such as zinc stearic acid, zinc bromide, zinc borate, phosphorization fluid etc. Also be used for preparation of the electroplating solution.
Characteristic and function:
1.Small granule, even granularity, high dispersing ability. Fast chemical reaction speed and can react completely with other material.
2.It’s high purity bring high purity to product when it is used as raw material. This assure the stale quality of product and reduce the impact on main products of other resultants.
3.The single granularity density and proportion are small and it is difficult to precipitate in the reaction process.
4.It’s pure white color reduce the influence to color of result compound.
