Micro-expanding Refractory Plastic

Micro-expansion refractory plastic High-temperature micro-expansion refractory plastic is made of a certain grade of low-iron and high-aluminum refractory aggregate as the main material, adding an appropriate amount of kyanite powder and binders and admixtures in a certain proportion. It uses water glass as a binder and introduces chemical coagulants. It shows good strength at high, medium and low temperatures, good plasticity at room temperature, micro-expansion at high temperature, high strength after high temperature, good sealing performance and convenient construction. It is a gas-hardening material.

Application field of high-temperature micro-expansion refractory plastic: High-temperature micro-expansion refractory plastic is widely used in metallurgy, petrochemical, electric power, building materials and other fields, especially in different parts of power plant boilers. When used above 1200℃, the material shows micro-expansion. It has strong plasticity at room temperature, strong adhesion, high strength after natural drying, micro-expansion of volume at high temperature, high refractoriness, good sealing performance, good high-temperature performance and refractoriness, excellent thermal shock stability, and convenient construction. It can be widely used in the top wall pipes, flame folding angles, and complex parts of furnace walls of industrial kilns such as CFB boilers and pulverized coal furnaces in the thermal power industry.
