MST' production process of Impurity free zinc oxide powder:

The MST® China Impurity free zinc oxide powder produced by MST all uses the best quality 0# zinc ingot (zinc content ≥99.995%) as raw materials. The metal zinc ingot is heated to 1300℃at high temperature, and the zinc ingot is melted and vaporized and then introduced into the hot air. Perform oxidation. Then, after cooling and cyclone separation, the fine particles produced are collected by a trap. Finally, the finished zinc oxide is graded and packaged through sampling, testing, and analysis.

Why choose China Impurity free zinc oxide powder produced by MST?

Because we strictly control the quality of Impurity free zinc oxide powder produced by MST, we can inspect every link:

1) Before the zinc ingot is put into production, conduct a full analysis and test on the zinc ingot to ensure that the quality of the raw materials meets the standards and strictly control the unqualified products;

2) During the production process of Impurity free zinc oxide powder, the regular items of zinc oxide produced are tested and tested, and samples are retained to ensure stable product quality.

3) Inspection before packaging: Before packaging, conduct a full analysis and laboratory inspection on China Impurity free zinc oxide powder, package it in categories and retain samples to ensure the quality of the finished product;

4) China Impurity free zinc oxide powder pre-factory inspection: Before leaving the factory, the zinc oxide products are sampled and tested to ensure that the products meet customer requirements.

5) Keep samples: We keep samples for each batch of products for six months for quality traceability or investigation.
