Chinese name: Zinc powder English name: zinc powder Chinese name 2: lead powder English name 2: Zinc dust Molecular formula: Zn Molecular weight: 65.39 Basic physicochemical properties: Color: dark grey; Molecular structure: spherical; Average gravity: 7.14g /cm33; Melting point: 419â??; Boiling point: 907â??. Solubility: insoluble in water, soluble in acid and alkali, ammonia; Stability: has a strong reducibility, and acid and base action to release hydrogen, easy to burn, combustion; Stable in dry air, a large amount of zinc powder can be burned in humid air; Burning in hot air produces a blue flame and produces zinc oxide. Flying in the air, the encounter of Mars can cause combustion, the allowable concentration in the air is 15mg/m3; It is easily caked by moisture, forming white basic carbonate in moist air and coating the surface; The reaction with sulfuric acid and nitric acid is slow, and the reaction is accelerated when there is a small amount of other metals such as copper, tin and lead. ã?? Main uses of metal zinc powder ã?? Huiyuan brand metal zinc powder is widely used in medical intermediates, electronic materials, military materials, zinc salt chemical industry, anticorrosive coatings, nonferrous and rare metal smelting and other industries.
Basic zinc carbonate(Transparent Zinc Oxide Powder), is a kind of inorganic carbonate, mainly as a raw materials of ceramic and lithopone manufacturing. Its specially used in transparent rubber products because of its refractive index similar to rubber. Bellow are the advantages in application in rubber 1. It is able to increase the thermal conductivity glue, improve the thermal conductivity and the curing rate, especially suitable for hot air vulcanization process. 2. It can improve the stability of the shape of semi-finished products in the curing process, which is suitable for non-model products (such as the based products which is the use of continuous vulcanization technology).
Anticorrosive treatment for ferrous metal production in electroplating industry, also used as metal surface treatment agent, used as colorant in ceramic industry. In surface treatment applications, used as an analytical reagent and anticorrosive agent, mainly in phosphating solutions for iron and steel parts. Used as embalmment of making black metal in the electroplating industry, capacity superior to manganese dihydrogen phosphate. Also used as anticorrosive and phosphatizing treatment chemicals of metal surface. In the ceramic industry is used as colorant and in the glass industry, it is used as clarifier.
