Product Description
Zinc oxide, also known as zinc white, is a pure white powder consisting of small particles that are amorphous or needle-like. As a basic chemical raw material, it has a wide range of applications, such as rubber electronics, medicine, coatings and other industries.
Zinc oxide (ZnO), commonly known as zinc white, is an oxide of zinc. Insoluble in water, soluble in acids and strong bases. Zinc oxide is a common chemical additive, widely used in plastics, silicate products, synthetic rubber, lubricating oil, paint coatings, ointment, adhesives, food, batteries, flame retardant and other products in the production. Zinc oxide has large band gap and exciton binding energy, high transparency, excellent luminescence performance at room temperature, and has been used in liquid crystal display, thin film transistor, light emitting diode and other products in the field of semiconductor. In addition, microgranular zinc oxide as a kind of nanomaterial also began to play a role in related fields.

Zinc oxide can be used as: feed nutrition enhancer, nutritional supplement (zinc fortifier); Rubber or cable reinforcing agent to make rubber have good corrosion resistance, tear resistance and elasticity, vulcanization activator for natural rubber, colorant and filler for white rubber; Fine particles (particle size of about 0.1μm) can be used as light stabilizers for plastics such as polyolefins or polyvinyl chloride; pigments for paints and fillers for rubber; In medicine, it is used to make ointment, zinc paste, rubber paste, etc.; Analytical reagents, reference reagents, fluorescent agents, and substrates of photosensitive materials; Electrostatic wet copying, dry transfer, laser fax communication, electrostatic recording and electrostatic plate making of electronic computers; In the redox capacity determination of manganese, it is used to precipitate salts that are easy to digest: such as iron, chromium, vanadium, Chemicalbook titanium and zirconium, which are used as hydrogen sulfide absorbers; Reference agent for the calibration of disodium ethylenediaminetetraacetate; A novel chiral framework material NaZnSiO3OH was prepared, which could be applied to ion exchange, adsorption or catalysis. Inorganic white pigment, coloring strength is not as good as titanium dioxide and lead powder, widely used in ABS resin, polystyrene, epoxy resin, phenolic resin, amino resin and polyvinyl chloride and paint and ink coloring; production of lacquered cloth, cosmetics, enamel, paper, leather, matches, cables, etc.; Printing and dyeing, glass industry, pharmaceutical industry, etc.; Used in plastic industry, sunscreen cosmetics products, special ceramic products, special functional coatings and textile hygiene processing; It is widely used in the deep desulfurization and purification process of industrial raw gas and oil such as m ethanol and hydrogen production.
