Zinc oxide 1.white powder and an amphoteric oxide 2.Competitive price and high quality. 3.Free sample
Zinc Oxide Description:
Nature:White powder, density 5.606, melting point 1975 0C, is an amphoteric oxide, insoluble in water or ethanol, soluble in acid-base solution, high temperature yellow, after cooling to restore whiteness
USED:
1. Rubber grade zinc oxide is used in radial tires, bias tires, conveyor belts, hoses, tape, rubber, latex gloves and other rubber products. Performance of their products fully comply with the requirements of the countries, the Ministry of Chemical Industry and American Standard
2 .Advanced ceramic zinc oxide is an important ceramic chemical flux materials in the building ceramic wall and floor tile glaze with low-temperature enamel material usage more. Also widely used in the art of glaze in ceramics, zinc oxide is widely used as transparent rough glaze translucent glaze of the tile glaze and crude pottery and craft cutlery dish or cooked glaze. Strong flux of zinc oxide in the glaze, to reduce the expansion coefficient of the glaze, to improve the thermal stability of the product, at the same time to increase the luster and whiteness of the glaze, improve the elasticity of the glaze. To increase at the same time expand the melting range of the glaze luster.
3. Soft ferrite with zinc oxide is mainly used for the electronics industry manufacturing deflection cores and other zinc magnesium ferrite core, as well as zinc oxide arrester related parts, the manufacture of components of the electronic structure of magnetic materials - Ferrite, TV, radio, electrical communication devices and rheostats, etc. The use of such magnetic materials.
4. Mainly used for cosmetics, skin care products and cosmetics to add material production industries
5. In the electronics industry, the arrester special zinc oxide is mainly used to manufacture the components of the electronic structure of magnetic materials – ferrite, TV, radio, electrical and communication devices and rheostats, etc. The use of such magnetic materials.
6. Pharmaceutical grade zinc oxide is mainly used for the production of creams, tablets, capsules and injectable drugs. Is a necessary component of many new drugs products.
7. For the production of high-grade paints, coatings and other products and coating intermediates.
8. Brand feed zinc oxide zinc additives at all levels of poultry, livestock, fishing, various types
