1, glazed tiles:
Mainly to see whether the surface of the tile has black spots, bubbles, pinholes, cracks, scratches, stains, missing edges, missing corners, etc.
Face defects! The quality of bricks with many defects is relatively poor!
2, glass tiles:
In addition to seeing brick surface black tiles, bubbles, pinholes, cracks, scratches, stains, missing edges, missing corners, etc.
Surface defects, but also pay attention to leaks, leaks and other defects.
No matter what brand of product, the embryo body should have the brand mark of the tile, check the bottom embryo trademark mark, regular manufacturers
The product's bottom embryo has a clear product mark on it. If it is not or is particularly vague, it is recommended to be careful!
The enamel is the component of the enamel, and the feel of the ceramic tile is the same as that of the same product. The quality and density of the same tile product are relatively heavy. On the contrary, the quality of the product is lighter. There is no direct relationship between the quality of the tiles and the thickness of the tiles. The main thing is to look at the density of the tiles!
Listen by tapping on the tiles and discriminating the tiles by listening to the sound. Tiles or small-size tiles are generally separated by one hand and five fingers, dragging the tile, and tapping the tile face with the other hand, if the sound produced is metallic The quality of the tiles is better, if the quality of the tiles without metal texture sounds worse!
(1) Wall tiles or small-size tiles are generally separated by one hand and five fingers, drag the tiles, and tap the face of the other hand. If the emitted sound is metallic, the quality of the tiles is better, if there is no metal texture. The sound quality of the tiles is poor!
(2) Floor tiles (glass tiles or antique tiles used in the living room and other floors) are tiled on one side with one hand and tapped in the middle of the tiles with the palm of the other hand. If the sound is thick and echoes are long If the sound of copper bells is struck, ceramic tiles have a high degree of porcelainity, strong wear resistance, high flexural strength, low water absorption, and are less susceptible to contamination. If the sound is turbid and there is no echo, the ceramicity is low (even exists Cracks) The calcined body of the tile is not fully calcined, the wear resistance is poor, the flexural strength is low, and the water absorption rate is also higher. Such a vitrified tile is extremely susceptible to contamination.
The products of the same specification and model will be randomly picked up and the four pieces will be spliced. Through this step, you can check the size, flatness and straightness of the tile.
(1) Check the size of the tiles. Take two pieces of the same model to the horizontal surface. Use the back of the two hands to slide back and forth along the edge of the tile. If there is no obvious lag when passing through the tiles, The feeling of the hand indicates that the size of the tile is better and the error is small. The smaller the tile size error, the better the tile effect will be! On the contrary, if there are obvious feelings of hand-stopping tiles, indicating that the tile size error is larger, it will affect the effect of paving!
(2) Check the flatness of the tiles. Two or four tiles of the same type are tiled on the plane with the same lines and slide back and forth on the tiles by hand. If there are no obvious seams passing through the tiles. The sense of high and low indicates that the flatness of the tiles is good. On the contrary, it shows that the flatness of the tiles is poor, which will affect the overall effect of the tiles. If the floor tiles are poor in flatness, the serious situation will trip people! So this should attract attention.
(3) Check the verticality of the tiles Nowadays, the tiles are mostly rectangular, and each corner of the tile is a right angle. If the straight angle is poor, it will also affect the tile effect. Take four pieces of the same type of brick. Splicing, if there are four tiles can not be closely seam, always one or two seams appear gaps, indicating that the tile's straight angle is not particularly good.
The fifth point: The test is mainly aimed at the non-slip problem of the floor tiles. For the floor tiles, the materials are mainly divided into two types: vitrified and glazed. For the current non-slip problem of tiles, everyone's current practice is to add water to the tiles. , and then step on the above to see if it is slippery, this practice is not entirely appropriate, because some tiles, especially glass tiles, add water, they will feel more involved, this principle is somewhat similar to the glass Add water, if you want to open the glass, it is difficult to find, because the water squeezed out the middle of the air, make the brick and the upper contact more closely, so I feel more involved, and some glass tiles without water Feeling more slippery, in this regard, my personal advice is to add water and not call the water in both steps to try it!
Check the anti-slip properties of vitrified tile can also take the following methods to identify
