广州万信水泥制品厂 的功能指标吗？ Do you know the functional indicators of Guangzhou Wanxin Cement Product Factory ? 广州万信水泥制品厂 就做了一个具体的介绍： The following is a detailed introduction of Guangzhou Wanxin Cement Product Factory :
Permeable bricks are made of inorganic non-metal materials as the main material, and are made after sintering or non-sintering and other molding processes.
The mechanical function of the permeable brick is relatively sensitive to the process conditions. The compressive strength and flexural strength increase with the decrease of the particle size of the material, and are proportional to the firing temperature. The participation of bentonite can not only improve the boring strength of the green body, but also improve the mechanical function of the product.
The smaller the particle size of the material, the higher the firing temperature, the better the abrasion resistance; the participation of bentonite can improve the abrasion resistance of permeable bricks ; the greater the molding pressure, the better the abrasion resistance of permeable bricks .
The change of the permeability coefficient of permeable bricks is closely related to the firing temperature, but is not greatly affected by the particle size composition of the material. In the case of a narrow particle size distribution, the influence of the molding pressure on the water permeability coefficient is small.
The porosity of water bricks decreases with the progress of firing temperature, and the influence of molding pressure on it is not obvious.
