Nowadays, many roads in the city have gradually changed to pavement tiles. The original floor tiles can not be compared with the new colorful permeable bricks in appearance or function. Colorful permeable bricks can beautified by spelling different patterns. The city has played a very good effect, and the colorful permeable bricks have the same water-permeable and breathable function as the permeable bricks, which can alleviate the problem of water accumulation on roads in rainy days. In addition, the "heat island effect" of summer cities can also have a suppressing effect.
The first is to make the fabric layer of colorful permeable bricks. The color of the colorful permeable bricks is generated by mixing various colors of cement, pigment powder and fine sand according to a certain ratio, and then it can be milled in a ball mill for about 15 minutes. Finish is still the color can meet the relevant national standards.
Another is to make the bottom layer of colorful permeable bricks. The bottom layer of colorful permeable bricks is made by mixing stone powder, waste stone, and some cement and curing agent, but it is necessary to pay attention to the stone powder, waste stone, and cement and curing. The composition of the agent is different, so the quality of the mix directly affects the quality of the base material and the strength and quality of the color bricks.
Then it is the process of pressure forming of colorful permeable bricks. Generally, the pressure forming liquid constrained brick machine is equipped with four worktables for four workers to operate in a cycle, one for each mold. First add colorful surface layer material (quantitative), and then add the bottom layer material to the plane of the mold frame. After being made into a high pressure by the brick making machine, it can be demoulded, stacked and maintained immediately. Due to abnormal product specifications, the molding pressure has also changed (the molding pressure can be arbitrarily scheduled). Simply transforming the mold can constrain products of various shapes and specifications, such as colorful pavement tiles, square tiles, grass planting bricks, slope protection bricks, and standard bricks. The output of Taiwan shifts is 2,000 to 7,000.
The last is to do the maintenance of colorful permeable bricks. This is also an appropriate and important step. It is the so-called traveling hundred miles and half-nineties. This is the reason. After many processes before, the last step is completed. If the later maintenance is done, If not in place, there will be a lot of unqualified products. The most important thing is to use steam for 24 hours.
