Product characteristics:
The highly active Zinc powder produced by our company has some characteristics of high contain of Zinc, low impurity elements, smooth surface, large surface area, small density of loose-powder, little oxide on surface, melting deformation and little grape shaped particles after sticking, average particle diameter is 0.1-4¦Ìm, total Zinc contain is more than 98.5%, metal Zinc contain is more than 96%.
Product Property:
Molecular formula: Zn
Molecular Weight: 65.38
Physical Property: light grey metal fine powder.
Density: 7.14g/cm3
Melting Point: 419.4¡ãC
Boiling Point: 908%
Chemical property: insoluble in water, soluble in acid and alkali, slowly soluble in acetic acid, ammonia water, it has strong reducing performance and give out hydrogen. Lumps when being wet, keeps stable in dry air and generates white basic carbonate covering in its surface in wet air. When combusting in the air, it can generate blue green flame and generate zinc oxide. High pure zinc act slowly with sulfuric acid and nitric acid, while act fast when it contains few of other metals such as steel, tin and lead.
Yechee provides a complete set of steel structure members for factory buildings, airport, stadium, station, bridge, thermal power plant, wind power project, commercial building & dwelling, crane system, communication tower, ocean engineering, ect. All the materials of our steel frame are c beam, z beam, h-shaped steel and thick iron plates or sheet, the grade is upon euro norm s355jrc or american norm astm a572 grade 50 or equivalent to q345b.
