1. Characteristics:
1. Huiyuan brand zinc oxide used specially in chemical industry has small particle size, medium grain size, scattered ability, high speed and thoroughly chemical reaction and consistent reaction rate.
2. High purity, high stability and little impurity. It greatly reduces the influence of other products to the main products.
3. Single grain's density and proportion are small. It is not easily to precipitation in reaction process.
4. It has pure white color. So it has no effect to the color of the products.
2. Usage:
Huiyuan brand zinc oxide used specially in chemical industry is widely used in the production of zinc stearate, zinc bromide, zinc borate, phosphorizing liquid and other products. It can also be used to allocate plating solution.
3. Product implementing standards:
