Understand the difference of clay bricks

Clay brick is a clay product with 30%-50% aluminum content. It is made of clay powder plus various refractory materials and binders. After being pressed and molded, it is sintered at a high temperature in a kiln. The clay brick is crushed by almost bauxite. After that, the mixing is stopped and the high-pressure machine is pressed to form. The properties of clay bricks made with different original materials are also different.

And the density and strength of the clay bricks made by using different presses to stop the compaction of the clay bricks in the brick molding process are also different. The clay bricks after the large-scale press stop the compaction will have higher strength after firing and molding than the small press molding. The brick strength will be greater. The raw material of clay bricks is also a decisive factor in determining the quality of clay bricks.

Clay bricks manufactured with rough materials will stop sintering after being pressed and will easily show cracks and other phenomena. Impurities will affect the separation performance of the clay bricks. The sintering performance will be affected. If the sintering temperature is high, the impurities in the bricks will be burned out to form clay. There are too many rough spots on the surface of the brick, and the lack of lubricity affects the appearance of the brick and the effect of the use of the brick.

Clay bricks must first stop the selection of original materials during the manufacturing process. The performance and appearance of products made from good materials are all qualitatively different, and the density, hardness, and refractoriness of the bricks have been greatly improved. Yes, a better clay brick will be made by adding a large amount of high-alumina fine powder in the clay and then passing through a high-weight press to stop the compression molding and firing.
