How to distinguish the good from the bad of ceramic tiles?

Ceramic tiles are the necessary materials for decoration, but we know little about the choice of ceramic tiles, often listen to others to introduce this good and that good, but the market materials fish dragon mixed with water and how much do we know? Today, let's talk about how to distinguish the good from the bad of ceramic tiles.     

Ceramic tiles, also known as magnetic tiles, are acid-and-alkali-resistant ceramic or stone building or decorative materials formed by grinding, mixing, pressing, glazing and sintering of refractory metal oxides and semi-metal oxides, which are called ceramic tiles. Its raw materials are mostly mixed by clay, quartz sand and so on. Ceramic tiles can also be divided into glazed tiles, through-body tiles, polished tiles, vitrified tiles, mosaics, etc.

Discrimination method:            

I. Look           

First, look at the water absorption of ceramic tiles. The lower the water absorption, the better the quality of ceramic tiles. How to look? Drip a drop of water to the back of the ceramic tile to see the diffusion area of the water drop. If the diffusion area is small, indicating low water absorption. Look at the label again, check whether there is a regular manufacturer's product label on the bottom embryo of ceramic tile, no or vague, it is suggested to choose carefully. At the same time, attention should be paid to whether there are black spots, bubbles, pinholes, cracks, scratches, stains, edges, corners, etc. on the surface of ceramic tiles, and whether there are defects such as leakage, wear and tear, and whether the glass tiles are deformed.            

II. Pinch            

After looking, if there is no problem with a pinch of components, try the feel of tile .If the feel of the tile is heavy, it means that the density is high and the quality is good. On the contrary, it is lighter and the quality is poor.            

III. Listening            

Listen to the sound can also distinguish the good from bad of ceramic tiles, but different ceramic tiles' knocking methods may be different. The following from the kitchen wall tiles and glass tiles to introduce two aspects:       

Tapping method:    

1) Wall tiles or small-sized tiles            

Separate with one hand and five fingers, hold up the tile, and tap the tile face with the other hand. If the sound emitted has a metallic texture, the quality of the tile is better;            

 2) Earth bricks (vitrified bricks or antique bricks used in living rooms and other floors). Lift one side of the ceramic tile with one hand and strike the middle of the ceramic tile with the upper part of the palm of the other hand. If the sound emitted is thick and the echo is long, the ceramization degree of the ceramic tile is high, the wear resistance is strong, the bending strength is high, the water absorption is low, and it is not easy to be polluted. If the sound is turbid and there is no echo, the ceramization degree is low (even cracks), the embryo body of the ceramic tile is not fully calcined, and the wear resistance is poor, flexural strength is low, water absorption is also higher. Such vitrified bricks are very vulnerable to pollution.            

IV. Opening            

Open the box for inspection to see if there is any damage. Pull the products in different boxes one by one. After paving, see if there is color difference and size.            

V. Spelling            

Take out 4 pieces of products of the same specifications and models at will and put them together. Through this step, the size, flatness and straight angle of ceramic tiles can be checked. 

VI. Trial            

As long as it is aimed at the anti-slip problem of ceramic floor tiles.
