Product Detail
Properties

Specially for pharmaceutical intermediate

Sample Nature:

Molecular formula:Zn

Molecular weight: 65.38

Physical property: Dark gray metal fine powder.

Density: 7.14g/cm³, Melting point: 419.58℃,

Boiling point: 907℃.

Chemical Properties:

It does not dissolve in water. It dissolves in acid and base. It dissolves in acetic acid and anunonia water slowly. It has strong reducibility. When it reacts with acid and base, hydrogen will be produced. It agglomerates under humid condition. It is stable in dry air. White basic carbonate is produced in humid air and it covers on the surface. When it is burnt in air, blue flame is produced. Besides, zinc oxide is generated. The product with high purity reacts with sulfuric acid,nitric acid and hydrochloric acid slowly. When it contains a little other met川such as iron, tin and lead, the reaction will accelerate.

Product Characteristics:

Huiyuan zinc powder used specially for waterborne inorganic zinc-rich paint has characteristics such as high metal zinc content,low content of other impurity elements, smooth particle surface and large specific surface area, low loose-packed powder density, less surface oxidation and less melting deformation and grape-like particles through adhesion. Total zinc content is more than 98.5%. Metal zinc content is more than 96%. The time for corrosion resistance is long and antiseptic effect is good.

Product Use:

The base material of Huiyuan zinc powder used specially for waterborne inorganic zinc-rich paint includes waterborne lithium silicate, waterborne potassium silicate, TEOS or cement slurry. The average particle size of zinc powder used specially for waterborne inorganic zinc-rich paint is 4-5 μm. The powder is distributed in narrow size fraction with good dispersion.
