Permeable brick is inorganic non-metallic materials as the main raw material, after sintering or free sintering process forming process is made with a larger water permeability of floor tile. Mechanical properties Permaeable more sensitive to the process conditions. Compressive strength, flexural strength with decreasing particle size and increasing raw material, and the firing temperature is proportional; bentonite is added not only can improve the drying body strength, but also improve the mechanical properties of products. Pervious performance quality, permeability coefficient and porosity are related to what it? The smaller size of the material, the higher the firing temperature, wear better; bentonite is added to improve the wear resistance of permeable brick; the larger molding pressure Permaeable wear also possible. Changes in permeability coefficient permeable brick and firing temperature have a great relationship, and not influenced by the composition of the raw material particle size. In the case of narrow particle size distribution, the smaller the impact molding pressure on permeability coefficient. Porosity Permaeable with the burning temperature increases and lower molding pressure its impact is not obvious. Permeable brick factory wholesale reasonable price!
