Corundum-mullite bricks are a high-hardness, high-strength building material made from corundum and mullite powders pressed at high temperatures. It has excellent mechanical properties and chemical stability and is suitable for use in demanding construction and industrial fields. Corundum mullite bricks can be used as high-temperature insulation materials, wear-resistant plates, kiln inner
walls, floor paving, etc., and have high use value and economic benefits.
Corundum mullite bricks have the characteristics of high hardness, high strength, high wear resistance, high temperature resistance, etc., and are suitable for the following fields:
1. High-temperature insulation material: As a high-temperature material, corundum mullite bricks can be used as lining and insulation materials for high-temperature equipment such as kiln inner walls, furnace roofs, flues, pipes, kiln tunnels, boilers, furnaces, electric furnaces, etc. High temperature resistance can reach above 1800℃.
2. Wear-resistant plates: As an extremely wear-resistant material, corundum mullite bricks can be used to make mechanical parts, sandblasting and shot blasting chambers, wind turbines, drums in the steel industry, scraper conveyors, etc. pieces.
3. Floor paving: Corundum mullite bricks have high hardness and wear resistance and can be used for floor paving in factories, warehouses, computer rooms, etc. that require wear resistance and anti-skid.
4. Other fields: Corundum mullite bricks can also be used in road sound insulation panels, building curtain wall materials and other fields.
In short, corundum mullite brick is a high-performance, high-stability building material suitable for various high-demand construction and industrial fields.
