There are many ways to classify ceramic tiles.
1. Classified by purpose
(1) Interior Wall Tiles: Glazed ceramic products with a water absorption of less than 21% for interior wall decoration. The main features are high glaze gloss, rich decoration techniques, and high appearance quality and dimensional accuracy.
(2) External wall tiles: Ceramic tiles with a water absorption rate of less than 10% are used for exterior wall decoration. According to different outdoor air temperatures, brick tiles with different water absorption rates are selected. In cold areas, bricks with a water absorption rate of less than 3% should be used. The glazed surfaces of the outer wall tiles are mostly semi-glossy (matt) or matt, and tiles with low water absorption are not glazed.
(3) Floor tiles: Ceramic tiles used for floor covering. The main features are high hardness, wear resistance, thick carcass, high mechanical strength, and good stain resistance.
2. Classified by material
(1) Porcelain tiles: The water absorption rate is less than 0.5%, the light transmission is good, and the cross section is delicate and shell-like.
(2) Semi-ceramic tiles: The water absorption rate is 0.5 to 10%, including enamel bricks, fine enamel bricks, and enamel bricks. It has poor light transmission, but it has high mechanical strength, good thermal stability, good chemical resistance, and a stone-like section.
(3) Ceramic tile: The water absorption rate is large, generally 10% to 21%. The green body has a low degree of sintering, is opaque to light, has a low mechanical strength, and has a rough surface.
3. Classified by forming method
(1) Dry pressing method (powder method): The slurry is made into a powder with a moisture content of less than 6%, and the powder in the mold is made into sheet-like bricks by a press.
(2) Plastic method (extrusion method, wet pressing method, roll pressing method, etc.): The mud material is made into a mud mass with a water content of about 20%, and after pressing, rolling, and other different pressure methods, it will be plastic. The mud pellets are pressed into sheet-like bricks.
(3) Grouting method: The slurry is made into grouting material and dehydrated by using a gypsum model. This molding method is inefficient and is used to produce special products with few parts.
In the performance testing of products, the inspection standards are usually selected according to the material and molding method. For example, the standard selected for testing porcelain tiles is the standard method of powder molding and porcelain tiles with a water absorption rate of less than 0.5%.
