Calcination of zinc oxide
It has high specific gravity, good fluidity, high effective purity, 30% lower harmful water-soluble salt than other counterparts, excellent glaze performance, and 2.0-3.0 vibration specific gravity can be adjusted according to user's requirements. The glaze produced by this method has small shrinkage, high smoothness, no pinholes, bubbles and cracks on the glaze surface, bright color effect and excellent sunshine fatigue resistance detection. The modified calcined zinc oxide in Xinrunfeng Zinc Industry has stable spherical structure, stable performance and uniform particle size. The company's conventional product content is 99%, 99.5%, 99.6%, 99.8%, other unconventional standard products can be customized according to user needs.
The properties of zinc oxide calcined by high temperature curve are stable. It can reduce the shrinkage of glaze surface, reduce the defects of bald glaze, bubble and pinhole caused by shrinkage, increase its density and fluidity, avoid thixotropy of glaze paste in the form of "tofu brain", and improve the properties of raw glaze. Calcinated zinc oxide has a strong melting aid effect in glaze, which can reduce the expansion coefficient of glaze, improve the thermal stability of products, increase the gloss and whiteness of glaze, improve the elasticity of glaze, improve the resistance of glaze color to temperature change, and enhance its chemical stability. When the amount of zinc silicate in glaze is supersaturated, the crystallization of zinc silicate can be formed.
