Detailed Description

Nanometer active zinc oxide is a kind of white and yellowish powder, which takes the inferior zinc oxide as the main raw material, after the sulfuric acid acidolysis, the removing of impurity, the precipitation, the separation, drying and the roasting. Compared with the ordinary zinc oxide, nm active zinc oxide has some advantages, that is, the small crystal particle, the large surface area and easy to disperse .Its particle diameter is only 1/10 to that of the ordinary zinc oxide, and the specific surface area is 10 times than that of the ordinary zinc oxide, which can achieve to 45 m2/g with the beehive shaped crystal form. It is characteristics of the good calendering and machining, easy to disperse and fill. Therefore it is widely applied in the industries of rubber, ceramics, glass, electric cable, high-quality coating. Nanometer active zinc oxide has the distinct advantages on reduction of the usage amount and the steady stabilization of physics machine capability, which is effective to improve the product quality and to reduce the cost evidently Quality index: CAQR003--2002 Zinc oxide % 93-96 Moisture content % ≤0.7 Loss on ignition % 1-4 Hydrochloric acid insoluble’s ≤ 0.02 Lead oxide (Pb)% ≤0.01 Manganese (Mn)% ≤0.001 screening residue (45um) % ≤ 0.1 Specific surface area m2/g ≥ 45 Bulk density g/ml ≥ 0.35 Average particle diameterΦ\um ≥ 60 25kg/bag
