Rubber industry: (1) greatly enhance the strength of the refractory products agents, reinforcing effect can be used at or near the level of silica. (2) improve dimensional stability, and stress crack resistance, enhanced toughness products, anti-aging, anti-cracking brand refractories, the wear resistance of reinforced article. (3) has excellent acid and alkali resistance, and flame retardant and anti-corrosion properties. (4) increase the heat resistance of the refractory product varieties, reduce shrinkage, warpage; neutral refractories may also improve product resistance to solutions of gas permeability, thermal expansion. (5) the use of neutral refractory insulation performance can improve the electrical properties of rubber products. · Terms of friction materials: silk basic refractories has good high temperature, anti-friction properties, can be made of automotive brake systems - clutch, brakes, etc., industrial grinding wheel. Neutral refractory ore deposit classification and distribution of China's domestic reserves of mineral resources neutral refractories, refractory materials are also widely distributed, but less worthy of exploitation. According genesis neutral refractories, refractory generally neutral neutral refractory ore deposit into schist type deposits (Chuzhou neutral refractory ore), porphyry alteration type neutral refractory deposits (Jingdezhen Willow Bay porcelain quarry), alteration of volcanic deposits in Neutral Refractories (southern Zhejiang, Fujian Nanan neutral refractories quartz rock, etc.), secondary quartzite neutral refractories illite deposits (eastern Zhejiang pyroclastic alteration neutral refractory ore type illite), clay, rock type neutral refractories illite deposits (Beijing Huairou, Southern illite clay minerals, etc.), in which the refractory ore schist Neutral exploitation maximum value, because the class feature neutral refractories refractory ore is most obvious. Which is good refractories, Refractories shangzhuang (certified), Hefei refractories by shangzhuang Refractories Co., Ltd., Zhengzhou City. Zhengzhou City shangzhuang Refractories Co.
