Physical properties of zinc oxide

2020-02-21

Zinc oxide is a white powder or hexagonal crystalline body, odorless and non-sandy. When heated, it turns yellow, and turns back to white after cooling. It sublimates when heated to 1800 degrees. Its covering power is half that of titanium dioxide and zinc sulfide. Its coloring power is twice that of basic lead carbonate. It is soluble in acids and alkalis, but insoluble in water and ethanol. It has a wide range of uses.

Zinc oxide It is a physical sunscreen that screens ultraviolet rays by absorption and scattering. As a semiconductor, the electrons in the valence band can accept energy from ultraviolet rays and undergo transitions, which is the principle of ultraviolet absorption. The functions of absorbing and scattering ultraviolet rays are related to the particle size of the material. If the particle size is smaller than the wavelength of ultraviolet rays, the particles can scatter ultraviolet rays in any direction, thereby reducing the irradiation intensity. If the particles are large, unnatural whitening will occur when applied to the skin. Surveys of various sunscreens have found this product to be effective and safe, and also has antibacterial and anti-inflammatory effects.

 

Shandong Xingyuan Zinc Industry Technology is Zinc oxide a manufacturer, and its products are widely used in rubber, ceramics, enamel, metallurgy, pesticides, magnetic materials, feed, glass medicine, electroplating, catalysts, electronics, paints, dyeing, military industry, coatings, and Dacromet technology, among other industries. Products are sold throughout the country and have received consistent praise from users. Its products have the following characteristics:

 

1. Strong activity, small particle size, strong dispersibility, and good vulcanization-promoting effect improve the cross-linking density of vulcanizates and make vulcanization more thorough.

2. The viscosity of the rubber can be better changed, improving the adhesion between rubber and steel wire and other skeleton materials such as fabric.

3. Good dynamic mechanical properties, small deformation of rubber products, less heat generation, good wear resistance, and good aging resistance.
