Application of laser particle size analyzer in zinc oxide

Zinc oxide is an oxide of zinc, which is insoluble in water but soluble in acid and strong alkali. It is a white solid, so it is also called zinc white. It can be obtained by burning zinc or roasting sphalerite (zinc sulfide). In nature, zinc oxide is the main component of the mineral zincite. Zinc oxide is used as an additive in a variety of materials and products, including plastics, ceramics, glass, cement, lubricants, paints, ointments, adhesives, gap filling materials, pigments, food (zinc supplements), batteries, ferrite Body materials, flame retardant materials and medical emergency bandages, etc. Zinc oxide is a wide-bandgap semiconductor material with a band gap of about 3.3eV at room temperature and an exciton binding energy as high as 60meV. It is expected to replace GaN as a material for ultraviolet LDs and LEDs. It has important applications in the field of optoelectronics.

Zinc oxide is extremely widely used, mainly used in rubber, plastics, paints, petrochemicals, glass, ceramics, pigments, batteries, cement, medicine and feed, etc. It is also used in photography and electrostatic recovery spacecraft coatings, manufacturing fireworks and smoke bombs, ammonium nitrate explosives and even cigarette filters.

This time Winner2018 is recommended to test zinc oxide powder samples for customers.

This test method is easy to operate, simple, fast, practical and instructive; it can be used to screen zinc oxide raw material powder during the production and processing of zinc stearate, screen zinc oxide raw material powder with suitable particle size, and avoid stearic acid During the zinc synthesis reaction process, the problem of uneven and insufficient reaction caused by the large particle size and poor dispersion of zinc oxide powder can effectively solve the problem of high residual zinc oxide particles in zinc stearate products, thereby ensuring that zinc stearate The product quality and purity have practical guiding significance for improving the quality of zinc stearate products. This time Winner2018 is recommended to test zinc oxide powder samples for customers.
