With the advent of the heating season, the bathroom must face the "double test", which must have good waterproof and moisture-proof ability, and must withstand the drying after heating and baking. Recently, many readers have reported the problem of wall tile detachment in the bathroom. After identification, the root cause is in the problem that the water absorption rate of the tile is easily ignored by most consumers.
Tile water absorption is easy to ignore
The Bohai Morning Post reporter found that the vast majority of consumers put the appearance of the product in the first place when purchasing ceramic tiles, and did not pay attention to the water absorption rate. Some consumers mistakenly believe that the lower the water absorption rate, the better. According to industry insiders, the water absorption rate refers to the adsorption and penetration ability of the ceramic tile. The low water absorption rate indicates that the product has high strength, is not easy to expand, and has high internal stability. However, tiles with too low water absorption may cause hidden dangers on the wall. When the low water absorption rate tile is used for the wall surface, it needs to be coated with higher viscosity to ensure the firmness; if the traditional cement sand is used, the water absorption rate of the tile is too low, which may cause hollowing and cracking. Tiles do not absorb and solidify the moisture contained in the cement slurry, which in turn loses the grip of the tile on the wall.
Paving methods also have an impact
The insiders have revealed the secret of water absorption rate: the water absorption rate of ceramic tiles is an important performance index of products, and the water absorption rate is different. The general consumers pay little attention when purchasing, generally only look at the strength and color. Aspects.
If the paving method is not appropriate, it is easy to cause the tiles to fall off. The Bohai Morning Post reporter learned that the wall tiles are covered with cement mortar paste method and thin paste method. Among them, the cement mortar paste method is a relatively common construction method, that is, the tile is immersed in the water for a certain period of time before the tile is laid, and the cement sand is mixed and debugged according to a certain ratio, and is smeared on the wall behind the tile. This method is suitable for ordinary light bricks and glazed tiles. Another method is the more popular thin sticking method, that is, before the brick laying, the leveling treatment is performed on the base layer of the wall, and then the tile adhesive is used to paste the tile on the wall, and the process is more complicated. This method is suitable for wall tiles with low water absorption and heavier water.
Distinct water absorption
How to judge the water absorption rate? The method is very simple. According to industry insiders, water absorption can be judged by simple methods such as dripping and tapping. For example, tapping on the sound carefully, the product with low water absorption sounds crisp and pleasing to the ear, and the water with high water absorption is dull; or dripping water on the back of the tile to observe the degree of water absorption, the water absorption rate is high, water seepage Slow or even no water absorption, the water absorption rate is low.
