Zinc Oxide (ZnO)-Powder

I. What is Zinc Oxide Powder?

Zinc oxide powder is a white or slightly yellow powder, which is an oxide of zinc, insoluble in water, soluble in acid and strong alkali. It is also a very common chemical additive, which is widely used in many fields today.

III. Applications of Zinc Oxide Powder

1. Mainly used as white pigment, rubber vulcanization activator, organic synthesis catalyst, desulfurizer, for electrostatic copying, pharmaceuticals, etc.

2. Used for desulfurization of synthetic ammonia, petroleum and natural gas chemical raw materials

3. Used as a matrix for analytical reagents, reference reagents, fluorescent agents and photosensitive materials

4. For electrostatic wet copying, dry transfer, laser fax communication, electrostatic recording of electronic computers and electrostatic plate making files

5. Used in the plastic industry, sunscreen cosmetics products, special ceramic products, special functional coatings and textile hygiene processing, etc.

6. Widely used in the deep desulfurization and purification process of industrial raw gas and oil such as synthetic ammonia, methanol and hydrogen production

7 Used as an astringent, used to make ointments or plaster

8. Mainly used as a reinforcing agent for rubber or cables, so that the rubber has good corrosion resistance, tear resistance and elasticity. Also used as vulcanization activator for natural rubber, colorant and filler for white rubber, vulcanizing agent for neoprene. Those with fine particles (about 0.1 μm in particle size) can be used as light stabilizers for plastics such as polyolefin or polyvinyl chloride.

9. Used as paint pigment and rubber filler, used in medicine to make ointment, zinc paste, plaster, etc.

10. It is suitable for supplementing zinc in feed processing.
