Method
The zinc ingot obtained by electrolysis is heated to 600-700℃ to melt, and then placed in a high-temperature resistant crucible to melt and vaporize at a high temperature of 1250-1300℃. Hot air is introduced for oxidation. The generated zinc oxide is cooled and cyclone separated, and the fine particles are captured with a cloth bag to obtain the finished zinc oxide product.
Applications
Food and Nutritional Products: In food processing, zinc oxide is used as a source of zinc to supplement zinc in food and improve nutritional value. It is commonly found in cereals, baby food and nutritional supplements.
Pharmaceutical industry: Zinc oxide is often used in ointments and anti-inflammatory agents. It has the effects of astringency, antibacterial and accelerated wound healing. It is often used in the treatment of skin diseases such as eczema, acne and diaper rash.
Electronics industry: Zinc oxide is a semiconductor material widely used in the manufacture of optoelectronic devices, solar cells, LED lights and transparent conductive films.
