Guangzhou Wanxin Ecological Ceramic Pervious Brick
Nowadays, the sidewalks on the street are mostly ordinary bricks, which will easily cause flooding if it encounters heavy rain. 广州万信水泥制品厂 出产一种新式的环保型砖，那就是 陶瓷 Now with the continuous progress and development of science and technology, Guangzhou Wanxin Cement Product Factory produces a new type of environmentally friendly brick, that is, ceramics ，可能有一部分朋友关于这个姓名不是非常的了解，那么究竟什么时候陶瓷生态透水砖呢？ Ecological permeable bricks , some friends may not know the name very well, so when exactly is ceramic ecological permeable bricks ? Raw materials of Wanxin through ecological ceramic permeable brick Adhesive: Low temperature adhesive mainly composed of polyvinyl alcohol, cellulose, water glass and several auxiliary agents. Clay: Use low-temperature and high-viscosity clay, in which the total amount of Al2O3 and SiO2 is less than 90%. Industrial waste: Industrial waste such as coal gangue, waste ceramics, and waste glass. Pore-forming agent: It is mainly composed of several organic materials, sawdust and carbonate. Production process The coal gangue, waste ceramics and waste glass are first crushed by a jaw crusher, and then the shape of the particles is uniformed by a ball mill. The particles are sieved into coarse and fine solid particles with a fine particle diameter of 0.05-2 mm and a coarse particle diameter of 2-6 mm. Mix water, adhesive and coarse and fine solid particles separately and evenly. Participate in the coarse-grained mixture on the bottom layer of the mold of the compactor and the fine-grained mixture on the upper layer of the mold. , Press molding under the pressure of 500-800 tons. Finally, it was put into a tunnel kiln, and it was dried at 100-120 ° C for 1 hour, and then calcined at 1160 ° C for 1.5 hours. After the temperature of the furnace is reduced to room temperature, the porous ceramic ceramic permeable brick can be made. According to the requirements of the user, in the production, you can participate in an appropriate amount of pigment in the upper layer of material and equip it into a permeable brick of different colors. Laying method of Wanxin through ecological ceramic permeable brick 1. Low-level processing. Level the foundation soil, tamp the ground, and lay a mixed layer of gravel and sand with a thickness of 100-150mm on the foundation. The proportion of stones and sand is 3: 1. 2. Sand cushion. On the mixed layer of gravel and sand, use medium sand to level and compact. The thickness of the cushion layer is 30-50mm. The cushion layer requires a flatness of ± 15mm and a mud content of less than 15%. 3. Laying. Lay the permeable brick according to the planning picture, and use the bake hammer to tap it from the side. After laying, ram the permeable brick with a high-frequency small plate and walk 3 times. 4. Marginal processing. The gap between the curb and the baseline of the paving bricks is filled with mortar or permeable bricks , and the permeable bricks are fixed with curb stones. Ceramic ecological permeable bricks -the use of environmentally friendly ceramic permeable bricks Environmentally friendly ceramic permeable bricks can be widely used in sidewalks, pedestrian streets, outdoor parking lots, public squares, house yards and other places. The environmentally-friendly permeable brick has increased the permeable and breathable space, and has played a very good role in adjusting urban climate and maintaining ecological balance. Therefore, the implementation and use of environmentally-friendly ceramic permeable bricks will definitely produce outstanding economic and social benefits.
