Diatomite thermal insulation bricks are made of high-quality diatomite, wood sawdust and high-temperature binder as the main raw materials. The raw materials are prepared, mixed and stirred, extruded, dried and then sintered. Diatomite thermal insulation brick contains a large number of micropores, which has the advantages of light weight, high compressive strength, low bulk density, low thermal conductivity, good energy saving and thermal insulation effect, high quality and low price. It also has the characteristics of non-deformation, non-toxic and odorless, and safe and convenient construction. It is an ideal material for wall insulation, insulation, and compartments; it can not only increase the temperature, shorten the heating time, and reduce fuel consumption. And has a good sound insulation and sound absorption effect. Diatomite thermal insulation brick is the choice of energy-saving and environmental protection equipment.
Diatomite thermal insulation brick product performance:
1. Thermal insulation products made of porous diatomaceous earth. The main raw material is natural porous diatomaceous earth, and a small amount of combined clay and combustibles are added.
2. The volume density of diatomite thermal insulation brick is 0.7g/cm3, the compressive strength at room temperature is 1～2MPa, the thermal conductivity at 400℃ is 0.13～0.20W/(m?K), showing that the porosity is greater than 70%. The coefficient of thermal expansion (at 1280°C) is 0.9×10-6°C-1, and the refractoriness is greater than 1250°C.
3. Diatomite thermal insulation bricks are mainly used as thermal insulation materials for industrial kilns and other thermal equipment and thermal pipelines. Generally, the temperature of the hot surface is about 1000℃.
