1) glazed tiles: face tiles made of clay or porcelain clay after being sprayed with glaze; This kind of brick is divided into two categories: one is fired with clay, which must be glazed because of its high water absorption. Because this kind of brick has low strength, it is rarely used now; The other is fired with porcelain clay. In order to pursue the decorative effect, the glaze is also fired. This kind of ceramic tile has dense structure, high strength, low water absorption and strong pollution resistance. The price is slightly higher than that of ceramic fired tiles

common specifications: 152 square glazed tiles × 152mm、200 × 200mm rectangular glazed tiles 152 × 200mm、200 × 300mm, and the thickness of commonly used glazed tiles is 5mm and 6mm

2) full body brick: this kind of brick is not glazed, and the surface is polished after firing, with patterns inside and outside; Full body brick is a kind of wear-resistant brick. Although there are still varieties such as porous full body brick, its design and color are relatively inferior to glazed tiles. It is widely used in the floors of decoration projects such as halls, corridors and outdoor walkways; Generally, it is rarely used on the wall. Most of the anti-skid bricks are full-length bricks

common specifications: 300X300mm, 400x400mm, 500x500mm, 600x600mm, 800x800mm, etc

3) polished brick: the whole brick is polished, thin, light and hard. After distinguishing the categories of ceramic tiles, you can make specific choices according to the use environment. Polished brick is a kind of all-round brick, which is hard and wear-resistant, and is suitable for use in most indoor spaces except toilets, kitchens and indoor environments. The disadvantage of polished bricks is that they are easy to get dirty

common specifications: 400x400mm, 500x500mm, 600x600mm, 800x800mm, 900x900mm, 1000X1000mm

4) vitrified bricks: in order to solve the problem of easy dirt of polished bricks, vitrified bricks appear in the market. Vitrified brick is actually a full ceramic tile. Its surface is bright and clean, but it does not need polishing, so there is no problem of polishing pores. Vitrified brick is a kind of strengthened polished brick, which is fired at high temperature. The texture is harder and more wear-resistant than polished bricks. There is no doubt that its price is also higher

common specifications: 400x400mm, 500x500mm, 600x600mm, 800x800mm, 900x900mm, 1000X1000mm

5) mosaic: it has many specifications, thin and small, hard texture, acid resistance, alkali resistance, wear resistance, water impermeability, strong pressure resistance, not easy to break, various colors and wide applications

a. ceramic mosaic. It is the most traditional mosaic. It is famous for its small and exquisite, but it is monotonous and low-grade

b. marble mosaic. It is a mosaic variety developed in the medium term, which is rich and colorful, but its acid-base resistance and waterproof performance are poor, so the market response is not very good

c. glass mosaic. The colorful glass brings vitality to the mosaic. According to the variety of glass, it is divided into many small varieties:

I) molten glass mosaic. It is a glass mosaic with silicate as the main raw material, which is melted and formed at high temperature and is milky or galactic, containing a small amount of bubbles and unmelted particles

ii) sintered glass mosaic. Take glass powder as the main raw material, add an appropriate amount of binder and press it into a green body with a certain size; Glass mosaic sintered at a certain temperature

iii) Venus glass mosaic. It contains a small amount of bubbles and a certain amount of metal crystal particles, and has a glass mosaic that flickers obviously when encountering light

common specifications: the common specifications of mosaic are 20 × 20mm、25 × 25mm、30 × 30mm, with thickness ranging from 4mm to 4.3mm

6) antique tiles

so how do we choose tiles correctly

look. Observe whether the brick surface is fine and uniform, and whether there are visible defects such as specks, holes, etc

quantity. Take a brick and measure whether its side length meets the requirements, then take several bricks and stack them together to compare whether their sizes are consistent. Take two bricks side by side and see whether the edge seam is small and straight, then the edge straightness is good; Then buckle the two bricks together to see whether the gap is small and straight, and the flatness is good. Whether the brick surface is concave or convex, it is better to be flat and slightly convex

knock. Gently tap (or snap with your fingers) the suspended tiles with a thin stick, and the crisp sound indicates that the tiles have no cracks, good sintering degree, low water absorption and high strength; If the sound is hoarse, the ceramic tile may have cracks; The sound "stuffy" indicates that the ceramic tile has poor sintering degree, high water absorption and low strength

drop. Drop a few drops of water on the back of the ceramic tile and observe the absorption speed. The faster the absorption, the greater the water absorption. Generally speaking, products with low water absorption have good sintering degree, high strength, good frost resistance and good product quality. Or apply several drops of colored liquid on the local surface evenly, wipe it with a wet cloth after a few seconds, and observe whether there are residual color spots on the surface. More color spots indicate that there are many pinholes, which are easy to get dirty, and the glaze quality is not high; If it cannot be wiped off, it means that the brick has high water absorption and poor anti fouling ability
