日本三菱化成株式会社研制成功一种耐高温硅酸钙制品。该制品在高温下强度降低率小,而且在不同温度范围内导热系数小,因此用途广泛,这种耐高温硅酸钙制品之所以能获得良好的耐高温性是掺用了碳化硅微粒。因为它具有耐高温和抑制高温下强度降低的作用。 该制品的生产方法是将石灰质原料与硅酸质原料分散于水中,加热下反应,得到含硅酸钙水化物的水性浆料,再加入碳化硅微粒和玻璃
Japan’s Mitsubishi Kasei Co., Ltd. has successfully developed a high-temperature calcium silicate product. The product has a low strength reduction rate at a high temperature, and has a small thermal conductivity in different temperature ranges. Therefore, the utility model has a wide range of applications. The high temperature resistant calcium silicate product can obtain good high-temperature resistance by using silicon carbide particles. Because it has high temperature resistance and the effect of reducing the strength at high temperatures. The production method of the product is to disperse calcareous material and silicic acid raw material in water and react under heating to obtain an aqueous slurry containing calcium silicate hydrate, and then add silicon carbide particles and glass.
