How to maintain and use ceramic permeable bricks?

Ceramic permeable brick is a high-quality permeable building material formed by using ceramic raw materials through screening and selection, reasonable organization of particle gradation, addition of binder, and then through molding, drying, and high-temperature sintering process. And it has the following characteristics: 1. Good water permeability

Ceramic permeable bricks are made of reasonable particle gradation, which can quickly pass through the precipitation of light to moderate rain. 2. High strength: The product is fired at a high temperature of 1200-1300, and the product bond is formed by the cooling of the physical components between the particles after melting, and the strength is very high.

Usually greater than 45 MPa. 3. Good freeze-thaw resistance: due to the large pores between the particles, the bonding is sintering, and it has good resistance to freeze-thaw in the north.

It solves the problem that the permeability of cement permeable bricks is good, but the freeze-thaw resistance is not good, and the freeze-thaw resistance is not permeable. 4. Good anti-skid performance: the surface particles of ceramic permeable bricks are coarse, the rainwater infiltrates quickly, there is no water accumulation and ice formation after rain and snow, and the anti-skid effect is better.

5. Good ecological and environmental protection performance: it can be produced from industrial wastes such as ceramic waste, sewer sludge particles, waste refractory materials, and fire gangue, and can be reused. After crushing, it can be fired again into bricks.

6. It can improve the urban microclimate and hinder the formation of urban floods: the porosity of ceramic permeable bricks is 20-30%, and it has a good water storage capacity. When sunlight is strong, water evaporation lowers the surface temperature and improves the microclimate. If a large area of pavement is formed, it can effectively block rainwater and reduce the probability of urban flooding.

If you want to absorb it well, maintenance is indispensable. In the construction of sponge city, ceramic particle permeable brick pavement has been widely used. Ceramic particle permeable bricks occupy a large proportion in the permeable pavement of the pavement.

Improper maintenance of ceramic permeable bricks after paving will lead to reduced water permeability, or even impermeability, which will greatly reduce the water permeability of the road.

1. Chewing gum (chewing gum).

Sprinkle salt water on top and let it freeze or harden before shoveling.

2. Animal manure.

Sweep, rinse with water, still not clean, wash with neutral detergent.

3. Rust. It is effective to remove with oxalic acid-based detergents.

4. Sludge.

Sweep and rinse with high-pressure water.

5. Oil stains (oil stains, grease, asphalt, etc.).

Remove with the corresponding detergent, methyl ketone, Tianna water, etc.

6. Paints (paints, coatings, latex paints).

After handling with the corresponding detergent or thinner, wipe it off with a dry cloth.

7. Moss (strictly speaking, it does not belong to pollution), crevice grass.

a.Clean the surface of the bricks in time to prevent humus-containing debris from attaching and staying, and moss will not grow.

b.If moss has grown, carefully remove it with a shovel and spray an appropriate amount of herbicide.

c.The grass is the same.

Ceramic permeable bricks are generally used in roads, squares and other outdoor hardened floors, so that rainwater can penetrate the road surface and flow into the ground, which is of great significance for improving road driving safety in rainy days, alleviating urban waterlogging, protecting underground water sources, and improving the urban ecological environment. On different occasions, ceramic permeable bricks should adopt different pavement maintenance and use schemes.

Ceramic permeable brick is a type of brick that is often used in urban ground, toilet and other scenes, the correct laying of ceramic permeable bricks is conducive to playing the role of ceramic permeable bricks, how to lay ceramic permeable bricks correctly? Today, PCHOUSE will answer them for you one by one.

1. The ceramic permeable brick should be treated with the base layer of the ground before laying. Clean up the debris on the base layer, and fully roll the roadbed before the ceramic permeable bricks are laid to ensure that the ground is flat, otherwise it will affect the accuracy of the subsequent construction.

2. After dealing with the base layer of the road surface, use a watering can to evenly sprinkle the ground base layer with water, but there can be no stagnant water.

3. Followed by the ash cake, the wall +50cm horizontal elevation line shall prevail, the surface elevation shall be measured, the horizontal line shall be pulled to make the ash cake, the upper skin of the ash cake block is the lower skin of the floor tile, the vertical and horizontal spacing is 1 meter, (bathroom and other rooms with water) according to the slope of 5 to find the slope in the direction of the floor drain. Clean the remaining slurry and brush the cement slurry binder layer (water-cement ratio is , and the interface agent with 15% water weight is mixed inside).

4. Then according to the construction requirements, play the grid mark to know the balance line, and then lay a permeable brick and punch the bar; Spread the evenly mixed cement on the ground, and then coat the bottom of the permeable brick with cement slurry and lay it on it in order, paying attention to the alignment of the gaps.

The correct purchase of ceramic permeable bricks can choose high-quality ceramic permeable brick products that meet their own needs. Today, PCHOUSE will answer them for you one by one.

Look at the purchase budget of ceramic permeable bricks. There are obvious differences in the products sold by different manufacturers in the market, before purchasing ceramic permeable bricks, they should estimate their budget, when purchasing ceramic permeable bricks, compare the product market with Zhengchang **, so as to choose the ceramic permeable bricks that are satisfactory to them within the budget, and can not be greedy for cheap and choose defective or "fake" ceramic permeable bricks.

2. Look at the manufacturers of ceramic permeable bricks. The production process of porcelain permeable bricks is cumbersome and complex, and it needs to go through multiple processes such as raw material crushing, screening, fine screening, independent batching, secondary distribution, and one-time strong pressure molding in order to produce products that meet market requirements.

3. Look at the use of ceramic permeable bricks. Ceramic permeable bricks can be roughly divided into step key Zen road bricks, sidewalk bricks, square bricks, garden bricks, courtyard bricks, and blind road bricks according to their use. Different specifications of ceramic permeable bricks should be used in different use scenarios to achieve the expected pavement effect.

4. Look at the strength of ceramic permeable bricks. The strength of high-quality Zhongguang ceramic permeable brick is more than twice that of ordinary pavement materials, with a compressive strength of up to 47MPa and flexural strength, which can be used for road and ordinary roads.

Ceramic permeable brick has the advantages of good slip resistance, good water permeability and water retention, when buying ceramic permeable bricks, people will not only pay attention to its advantages, but also understand the disadvantages of ceramic permeable bricks, so what are the disadvantages of ceramic permeable bricks? Today, PCHOUSE will answer them for you one by one.

1. Ceramic permeable bricks are relatively easy to damage, ceramic permeable bricks are mainly used for the laying of urban pavement, and ceramic permeable bricks need to be repaired and maintained by relevant departments after damage, which may lead to high pressure on relevant departments. Moreover, the ground of ceramic permeable bricks is easy to be uneven after damage, and pedestrians are easy to bump and fall when walking.

2. The splicing of ceramic permeable bricks is more time-consuming, and it is easy to splice unevenly. If the ceramic permeable brick is unevenly spliced, it will cause the inside to be uneven, and it is easy for pedestrians to bump and fall when walking, or to bump and unstable when riding.

3. After the ceramic permeable bricks are laid, there are many gaps, which are prone to dust accumulation and debris deposition, but there is no relatively mature technology to remove the dust, impurities and other deposits accumulated in the cracks of the permeable bricks.

Ceramic permeable brick is a kind of brick that is easy to lay uneven, pay attention to some details when laying ceramic permeable bricks to make the laying effect better, so what are the precautions for laying ceramic permeable bricks? Today, PCHOUSE will answer them for you one by one.

1. Before laying ceramic permeable bricks, it is necessary to do a good job in the treatment of the base layer. No matter what type of bricks are paved, the foundation treatment of the base is very necessary, and only the smoothness of the base can ensure that the bricks are paved in good condition. If there is debris on the ground to be cleaned up, the gravel should also be compacted, and the gravel layer should be paved to see if there is a thickness of 10 cm.

2. When laying ceramic permeable bricks, it is necessary to lay them again and again to check the flatness and firmness of the pavement, and if there is a problem with the flatness and firmness, it should be repaired immediately. In addition, the cutting of ceramic permeable bricks should be cut using a professional cutting machine.

3. After the ceramic permeable brick is laid, it is necessary to pay attention to the sprinkling acceptance. After the ceramic permeable brick is laid, it is necessary to carry out sprinkling acceptance, to evenly sprinkle water on the surface of the permeable brick, to let the sand inside expand, so as to avoid the loss of quicksand, and the laid permeable brick can not be rained, and it can be put into use after standing for more than 6 hours after acceptance.

1. Because it is laid outdoors, it is prone to quality problems due to long-term wind and rain and vehicle crushing in some areas.

2. There are many internal gaps in the brick body, so the compressive and bending strength is low, and the wear strength is low. There are compressive and bending problems such as easy breaking.

3. It is easy to be damaged, and the relevant departments need to repair and maintain it again after the damage, which may lead to high pressure on the relevant departments.

4. There is no relatively mature technology for permeable brick products to remove dust, impurities and other deposits accumulated in the cracks of permeable bricks.

The permeability of ceramic permeable bricks is good, the porosity is up to 40%, and most of the rainwater can seep into the ground when it rains, so that the groundwater can be naturally replenished. It can alleviate the problem of declining groundwater levels and reduce the pressure on urban drainage channels. The material of ceramic permeable brick can be ceramic raw materials, or it can be spontaneously combusted industrial waste, coal gangue, waste tiles, quartz, etc., which is a truly environmentally friendly material.

In line with the environmental protection concept advocated in today's world, it is also known as ecological environmental protection bricks.

Non-burnt product classification: two-layer structure silica sand permeable bricks, single-layer permeable cement bricks, adhesive stone bricks. (The latter two old products have been gradually eliminated from the market).

Two-layer structure silica sand permeable brick: the lower layer is a permeable concrete structure, the upper layer is a sand bonding structure, the density difference between the two layers of materials is large, the expansion coefficient is different, and the temperature difference between day and night is large, and the structure is unstable. The technical obstacle of silica sand permeable brick is the combination of cement layer and sand base.

We know that different substances have different physical properties, so their coefficient of expansion is also different. Take silica sand permeable brick as an example, it uses an organic glue as an adhesive to bond the sand base layer with the cement layer, so that there are two obvious risks in the process of use. On the one hand, due to the different expansion coefficients of the cement layer and the sand base, the product is easy to cause delamination in the process of use, which affects the strength and use of the product. Second, because the surface sand-based molding is made of organic adhesive bonding, and the adhesive is an organic matter, the organic matter is very easy to weathered under natural conditions, and the adhesive is weathered, so the strength of the product cannot be guaranteed, and it is not of much use.

Single-layer permeable cement brick: Because cement is an alkaline material, it is easy to react in case of acid rain (panalkali phenomenon) and is easy to weathering and decomposing. Adhesive stone bricks:

Due to the use of organic materials bonded, exposed to wind and sun, aging and degeneration will occur in about two years, resulting in problems such as fragile and fragile materials.

Permeable brick in a certain permeability at the same time, should also have a good anti-skid function and decorative effect, permeable ground permeability depends on the brick permeability and brick joint permeability, in the actual use process should also consider its air permeability, anti-slip and decorative effect. Color retention. High-quality floor tiles should have good color retention performance, and the pigments used are iron oxide inorganic pigments.

For light-colored concrete permeable bricks, when white cement has to be used as cementitious material, gray cement should be used as the base material as far as possible, and white cement should be used as the surface layer material composite pressure vibration molding process to maintain the good color retention and compressive strength of the pavement bricks, and avoid the serious "white birch" phenomenon. Laying method. Rectangular (Dutch long) floor tiles generally have four weaving methods, different laying methods not only produce different decorative effects, but also greatly affect the mechanical properties of the ground, for the heavy-duty ground, and the direction of the car at an angle of 45 degrees of "human" shape paving mechanical properties are the best, "one" shape and "flower basket" laying is generally only suitable for sidewalks and bicycle lanes.
