Zinc oxide used specially in chemical industry

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.

Properties

Zinc oxide is a kind of pure white powder, which is composed of amorphous or needle like small particles. As a basic chemical raw material, it has a wide range of applications, such as rubber electronics, medicine, coatings and other industries. Zinc oxide can be used as white pigment in printing and dyeing, papermaking, match and pharmaceutical industry. In rubber industry, it is used as vulcanizing agent, reinforcing agent and colorant of natural rubber, synthetic rubber and latex. It is also used in the manufacture of pigment zinc chrome yellow, zinc acetate, zinc carbonate, zinc chloride, etc. In addition, it is also used in electron laser materials, phosphors, feed additives, catalysts, etc. In medicine, it is used to make ointment, zinc paste, rubber paste, etc.
