nm active zinc oxide

Product Description

Nm 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 dismeter is only 1/*0 to that of the ordinary zinc oxide,and the specific surface area is *0 times than that of the ordinary zinc oxide, which can achieve to *5 m2/g with the beehive shaped crystal form. It is characteristics of the goodcalendering and machining,easy to disperse and fill. Therefore it is widely applied inthe industriesof 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
