The water absorption rate of ceramic tile is one of the important indicators for evaluating its quality and applicability, which directly reflects the density and hardness of ceramic tile. According to the different water absorption rates, ceramic tile is divided into different categories to meet different usage requirements.
The classification standards for water absorption rate of ceramic tile are as follows:
Porcelain tile: water absorption rate is less than or equal to 0.5%. This type of ceramic tile has high density, high hardness, strong stain resistance, and is suitable for indoor floor and wall decoration. Polished tiles, vitrified tiles, and antique tiles from some manufacturers belong to this category. Due to the extremely low water absorption rate, this type of ceramic tile does not need to be pre-soaked when paving, and it is not easy to deform or crack due to water absorption.
Stoneware porcelain tile: water absorption rate is greater than 0.5% but less than or equal to 3%. This type of ceramic tile has a moderate water absorption rate and good anti-slip performance. It is suitable for floors and walls in humid environments such as toilets and bathrooms.
Fine stoneware tile: water absorption rate is greater than 3% but less than or equal to 6%. This type of Ceramic tile has a slightly higher water absorption rate and is suitable for exterior wall decoration and certain indoor environments.
Stoneware tile: water absorption rate is greater than 6% but less than or equal to 10%. This type of Ceramic tile has a higher water absorption rate and is mainly used for outdoor floor and wall decoration, such as squares, sidewalks, etc.
Ceramic tile: water absorption rate is greater than 10%. This type of Ceramic tile has the highest water absorption rate and is usually called interior wall tile. It is widely used for wall decoration of buildings such as residential buildings, hotels, restaurants, and public places. Due to its high water absorption rate, it needs to be fully soaked before paving to ensure a firm bond with cement mortar.
In general, the water absorption classification standard of Ceramic tile is divided according to its different water absorption rates. Ceramic tiles with different water absorption rates are suitable for different use environments and decoration needs. When purchasing Ceramic tile, consumers can choose the appropriate Ceramic tile type according to actual needs and use environment. At the same time, water absorption rate is also one of the important indicators for evaluating the quality and performance of Ceramic tile, and consumers should pay attention to it when purchasing.
