1. Identify the brand:
At present, China's permeable brick shopping malls are relatively complicated. There are not many large manufacturers, but more small manufacturers and small workshops. The permeable bricks produced by these manufacturers cannot make a strong guarantee in quality. Therefore, when buying permeable bricks, the first thing to look at is the brand. Select some of the larger domestic manufacturers and trust the strength of the brand.
2. Observe the appearance of the water brick:
At present, domestic permeable bricks are roughly divided into two types. One is to permeate through the pores on the outer surface of the brick, and the other is to permeate through the gap between the brick and the brick. The appearance of bricks is relatively rough, and the permeable bricks on the market are relatively rough and the pores are very large. The permeable bricks have a relatively low service life and short permeable times. It is simply blocked by dust. Once it is blocked, it loses the function and value of the permeable brick. However, the cost of this large-pore permeable brick is relatively low. We should choose the permeable brick with a very fine appearance and the permeable brick Long time and long service life. At present, a kind of permeable brick made of sand is relatively popular on the market.
3. Check the permeation aging, service life, permeation speed and other data:
Specifications for inspecting the quality of permeable bricks: 1. See how long the permeable bricks are permeable; 2. See how the permeable bricks are used; and 3. See how permeable bricks are. These three specifications are the litmus test for the inductive quality of permeable bricks.
4, look at the price:
The price and cost have always been our concern. It is the so-called price and goods. It makes sense to be expensive and cheap. In fact, the price selection is also very simple. If you are interested in immediate interests, you can choose ordinary permeable bricks. If you are interested in long-term interests, then choose high-quality permeable bricks to ensure years of water permeability, and the quality is very good.
