What is the reason for the cracking of tiles?
The cracking of floor tiles is divided into the crack of glaze and the cracking of the embryo. Because of their geological problems will cause a certain degree of subsidence, resulting in wall deformation and cracking, but also caused cracks in ceramic floor tiles. The cracking situation is generally a coherent and regular crack. Pry the rustic tile and shovel the cement mortar to see if the wall is cracked or deformed. The walls that have just been reformed do not immediately paste the tiles.
Used the High standard cement. The tiles are usually made of ordinary 425 ordinary silicate cement, and the proportion of cement sand is 1:3. If the cement label is too high, when the cement mortar solidify, the cement will absorb the moisture in large quantities. When the moisture of the tile is absorbed too much, it will be easily cracked. Many flooring tiles cracked, and the direction of cracking texture was irregular.
The glazed ceramic tiles are covered with empty drum make the tiles are cracked. The expansion coefficient of cement mortar and tile design is different due to the hollowing and non hollowing parts, resulting in deformation and cracking of tiles. The cracked tiles are irregular in distribution, and the cracks are irregular. The cracks are linear and vary in length. Take a coin to knock the tiles surface, listen to the sound, see whether it is hollowing? The sound of the knocking is low and cloudy, that is, the empty drum.
The slots will also cause the tiles to crack. No cracks are laid on the tiles, the expansion of the ceramic tile cost and the foundation layer is not consistent, and the thermal expansion and cold contraction cause the marble flooring to crack. Tile edges and corners are split, the surface cracking texture is fine, and the texture is relatively short. It is suggested that the paving should be kept in the gap. The tiles are cracked due to insufficient water before wall tiles. When the water is not enough, when the cement mortar is solidified, the cement absorbs moisture and causes the marble tiles to crack. The cracked tiles are irregular in distribution, irregular in cracks, irregular in shape and different in length. Water is not enough to cause tiles cracking generally appear after tiles paving soon.
Smashing walls causes vibration of tiles price and cracks. If the next door neighbor is decorated behind, the wall will be vibrate and the stone wall tiles will be cracked. The cracked wall stone are concentrated on the wall that is close to the neighbours. The tile was cracked by the impact of the external force. For example, direct impact of heavy objects will also cause cracking of tiles. The number of cracked tiles is small, and the cracking texture is reticulate. From the surface, the surface of cracking is damaged.
The ceramic tiles that have been cut and processed are cracked. During the cutting process, a dark crack is formed. After a period of time, the tiles are cracked due to the influence of cement shrinkage and external force. It is easier to distinguish. If there are more marbling for cutting, BARANA recommends that they be processed to professional paving plants and then put to the shop. The tiles are so close to the fire stove that the color tiles are cracked. It is too close to some heat sources and is affected by supercooling and superheated temperature. The thermal expansion and cold contraction cause tiles cracking. This phenomenon usually occurs in the kitchen and boiler room.
The quality of the colors tile itself causes cracking. Tile quality problems generally have two points: first, some tiles water absorption rate is high, the degree of compression is not enough, resulting in tile cracking; Second, the tiles are not burned in the firing process, causing cracks in transportation, storage and use. The quality of tiles are generally characterized by mesh, such as the size of the fine hair, the relatively high proportion of cracking, and the possibility of cracking in a tile. This situation generally occurs in lower grade products.
Generally, when the tiles cracks occur, everyone will think that this is the quality problem of glazed rustic tiles. In fact, the production technology of polished tiles factory is relatively mature now, and the quality control is also very stable. Generally speaking, the quality of tiles basically goes through the border. From the various reasons mentioned above, we can see that there are many reasons for the cracking of the tiles, not only the problem of marble porcelain tiles quality. Most of the problems are due to external causes.
