Permeable brick is the basic material of the construction of sponge city brick, pavement high-grade material permeable brick, test and measure a qualified quality standard of permeable brick, in addition to the overall appearance smooth, but also look at its permeable aging, speed, service life,

Compressive strength, folding resistance, frost resistance. With the continuous standardization of the construction requirements of sponge cities, the permeable bricks produced by some manufacturers using poor brick machine equipment are difficult to meet the market standard requirements, but they are eliminated.

Liushi machinery tells you that we must use good brand manufacturers brick machine equipment products, brand is the guarantee of quality, there are many brand manufacturers in the market, and there are great differences in quality, when choosing brick machine equipment, we need to know more

According to the actual investigation, the quality of the manufacturer's products has been widely recognized and trusted by the market, and the permeable bricks produced by such manufacturers are more secure.

Of course, good brick equipment is on the one hand, the raw materials and methods of making permeable bricks are also very key, so let's take a look at the advantages of permeable bricks how to facilitate it! To Liu's machinery Co., Ltd. for many years of experience to tell big

Home, first of all, look at the overall appearance of permeable bricks, some manufacturers of permeable bricks are relatively incomplete appearance is very rough, the gap is very large, the corners are still incomplete, the pavement will be able to see the past, carefully look at the brick special time, this brick

The selling price will be low, but the service life is also very low, the effect is poor, can not reach the good effect and value, secondly, look at the material particles, a good permeable brick bottom material and fabric material requirements are also very high, the size of particles should be uniform and clean,

Some in order to reduce the cost of brick making, a large number of powdered tail material into it, which will cause blockage of the brick gap, affecting the water permeability effect, a long time will no longer have water permeability, must be strict requirements, scientific ratio. Finally, look at the brick inspection standard,

The strength of permeable brick is greater than or equal to 35MPa, the bending resistance is greater than or equal to 6MPa, the penetration coefficient is greater than or equal to 0.1mm/s, and the anti-freezing mark is greater than or equal to 50 times, which is to meet the national standard and the local standard requirements.
