Zinc oxide by direct method

Use:
1, in the rubber and tire industries, the zinc oxide is essential additives, can be used as natural rubber, synthetic rubber latex and a vulcanizing agent and reinforcing agents and coloring agents.
2, in the chemical industry, zinc oxide is widely used as a catalyst, desulfurization agent, such as a methanol synthesis catalyst, as when ammonia desulfurization agent.
3, in the coatings industry, in addition to zinc oxide having a hiding power and tinting strength, but also is a coating agent as a preservative and emitting
4, in the glass industry, zinc oxide is used in special glass article.
5, in the ceramic industry, zinc oxide used as a flux.
