Introduction of Low Porosity Clay Brick
Low-porosity clay bricks are mainly made of high-alumina bauxite and scorched gemstones, which are prepared by adding sillimanite and andalusite in proportions, adding binders and adhesives, kneading, forming, drying, and then kiln firing. Low-porosity clay products.
Characteristics of low-porosity clay bricks
1. The apparent porosity is low and the compactness is strong.
2. Good penetration resistance and erosion resistance.
3. High temperature strength and long service life.
Application of Low Porosity Clay Brick
Mainly used in the regenerator of glass kilns, it can also be used in blast furnaces and hot blast furnaces in the iron and steel industry; cement kilns in the building materials industry; chemical kilns in the chemical industry as kiln linings. Features of low-porosity clay bricks: high strength, high refractoriness, compact structure, low pores, good thermal shock stability, and anti-stripping.
