How To Choose Insulation Bricks?

Ordinary thermal insulation bricks, the use temperature is below 1000 ℃, mainly include diatomaceous earth bricks, expanded razor stone bricks, expanded perlite bricks, etc., and are mostly used as heat insulation layers for thermal equipment.

Refractory and thermal insulation bricks are used at temperatures between 1000 and 1500°C. They mainly include light clay bricks, light silica bricks, and light high alumina bricks.

High-temperature insulation bricks are used at temperatures above 1500°C and can be directly used as furnace linings for high-temperature kilns. They mainly include lightweight corundum bricks, hollow alumina sphere products and zirconia hollow sphere products.

Ultra-high temperature insulation bricks are made of fibrous materials such as silicon fiber, aluminum fiber, carbon fiber, nitrogen fiber, silicon carbide fiber, at least one heat-resistant inorganic material such as silica, alumina, lithium oxide, magnesium oxide and adhesive The aggregate is used as the raw material and is formed by molding and sintering. This kind of brick is lightweight and high-strength, has excellent ultra-high temperature heat resistance and thermal conductivity, is easy to process, and is suitable for aerospace devices, industrial furnaces, etc.
