Glazed tiles, also known as interior wall tiles, are the tiles whose surface has been glazed. They are also the most commonly used tiles in daily life. This kind of brick is divided into two types according to the raw materials: one is fired with clay, and the other is fired with clay. At present, about 80% of buyers of home decoration choose glazed tiles as floor decoration materials, but glazed tiles, also known as interior wall tiles, are the tiles whose surface has been glazed, and they are also the most commonly used tiles in daily life

this kind of brick is divided into two types according to raw materials: one is fired with clay, and the other is fired with porcelain clay. At present, about 80% of buyers of home decoration choose glazed tiles as floor decoration materials, but because the surface of glazed tiles is glaze, the wear resistance is not as good as polished tiles

according to the shape, it can be divided into square, rectangular, rectangular, special-shaped accessory bricks and other varieties. Square glazed tiles are 100x100mm, 152× 152mm、200× 200mm, rectangular glazed tiles have 152× 200mm、200× 300mm, 250x330, 300x450, etc., and the thickness of commonly used glazed tiles is 5mm-8mm

it can be divided into wollastonite, pyrophyllite, porcelain stone, limestone and feldspar according to its composition

the main physical properties of glazed tiles are: resistance to rapid cooling and heating, no cracking at one time, and the water absorption is no more than 22%>, Whiteness not less than 78%, good corrosion resistance

scope of application: it is suitable for various places of indoor decoration, and the wall is the best. For kitchens, bright bricks should be used as much as possible, and matte bricks should not be used. It is also used as an acid resistant tank

common quality problems mainly include two aspects: 1. Cracking: the root cause of cracking is that the stress between the blank and glaze exceeds the difference of thermal expansion coefficient between the blank and glaze. When the coefficient of thermal expansion of the glaze is greater than that of the blank, the shrinkage of the glaze is greater than that of the blank when it is cooled, and the glaze will be subject to tensile stress. When the tensile stress is greater than the ultimate strength that the glaze layer can bear, cracking will occur. 2. Back seepage: no matter which kind of brick, water absorption is natural, but when the density of the green body is too loose, it is not only the problem of water absorption, but the problem of cement seepage. That is, the sewage of cement will permeate the surface
