I believe everyone knows that after the tiles are bought and put home, it will not be all right. Many homeowners may encounter cracks that have been cracked for no reason after the tiles have been laid for a while. The owner who lacks professional technical knowledge does not know what the reason is and who the responsibility should come from.
1. Material problems
If the cement label is incorrect, it will cause cracking. Tile tiling generally uses 425 ordinary silicate cement, cement sand mixing ratio is 1:3, if the cement label is too high, when the cement mortar solidifies, the cement will absorb a lot of water, then the tile moisture is absorbed too much Cracking.
Crack: Many tiles crack and the cracking texture is irregular.
2. Geological problems
Because the geological problems in itself will cause a certain degree of sinking, the wall will be deformed and cracked, causing the tiles to crack.
Crack: Cracking is generally a coherent and regular crack.
Resolution method: Open the tile, shovel the cement mortar, and check whether the wall has cracking deformation.
Note: Do not tiling the wall immediately after the transformation.
3. Construction problems
1 When the tile is laid, the hollow drum phenomenon occurs, while for the hollow and non-empty drum parts, the expansion coefficients of the cement mortar and the tile are different, causing the tile to deform and crack.
Crack: The cracked tile is irregularly distributed, the crack is not regular, and the crack is in the shape of a line, and the length is different.
2 The paving does not leave a seam, the tile and the base layer are inconsistent in expansion and contraction, and the thermal expansion and contraction causes the tile to crack.
Crack: The corners of the tile are cracked, the surface cracking texture is fine, and the texture is relatively short.
Note: It is recommended to leave at least 1~2mm gap for paving.
3 In addition, if the tile with a certain water absorption rate is not soaked before the paving, the tile will absorb the moisture in the process of cement mortar condensing and strength rising, and the brick surface will also crack due to the tensile force of the cement mortar. Insufficient water soaking, cement will absorb uneven water, it will also cause the tile to crack.
Resolving method: insufficient water so that the tile cracking usually appears shortly after the tile is laid.
4, force majeure
1 Direct impact by heavy objects or other external impacts may also cause the tiles to crack.
Crack: less cracked tiles, cracked texture is mesh
2 ç ¸ wall and other causes the wall to vibrate and cause the tile to crack.
Crack: Cracked tiles are concentrated on walls close to their neighbors.
3 During the cutting process, a crack is formed. After a period of time, the tile is cracked due to the shrinkage of the cement and the external force.
Note: When there are more tiles, it is recommended to go to the professional processing factory and then pull it to the site for paving.
5. Environmental factors
It is too close to the heat source such as the fire stove, subject to temperature changes caused by overheating and overheating, and the thermal expansion and contraction causes the tile to crack.
6, tile quality problems
Failure to meet the standard production of ceramic tiles may lead to cracking. First, some bricks have higher water absorption rate, and the pressure resistance is not enough, causing the tiles to crack. Second, the bricks are not burnt through during the firing process, causing cracking during transportation, storage and use. Third, if the hardness of the tiles is not enough, It is easy to crack when the load is too high or damaged during use.
Crack: The quality of the tile itself, the cracked texture is generally mesh-like, such as the size of the fine hair, the proportion of cracking is relatively high, and there may be many cracks in a tile.
In summary, in addition to environmental, construction, materials and other issues, the quality of the tile itself can not be ignored. As a first-line brand of ceramics, Jinai Ceramic Tiles adheres to the production philosophy of quality as the first goal. It uses high-quality raw materials, automated production lines and balers for tile production. Each batch of products undergoes strict quality inspection before leaving the factory. Create high-quality ceramic tiles with beautiful appearance, good quality and not easy to crack, so that every customer can buy with confidence and use them with peace of mind.
The inner surface of the zirconia ceramic plunger adopts a fluid structure with no dead angle and groove; and the inner cavity surface is matched with the surface of the plunger, and is also processed to the mirror surface by an advanced high-precision inner and outer cylindrical grinding machine, and the outer surface is vibrated and polished for convenient cleaning. ,disinfection.
Since zirconia ceramic plungers have so many advantages, they certainly attract more users. Compared with metal plungers, zirconia ceramic plungers are not only more durable, but also have better effects and can meet some special requirements. Application requirements under working conditions.
