Tips for identifying the quality of ceramic tiles

1. Look: Look at the color uniformity and surface finish of the tiles. Take out four or five tiles from a box and wear glasses (if you It is not necessary if the visual acuity is above 1.5), check for defects such as color difference, deformation, missing edges and corners.

2. Knock: tap the brick body with a hard object. The crisper the sound, the higher the vitrification and the better the quality. You can also hold the corner of the tile with your left thumb, index finger and middle finger, hang it down easily, and tap the middle and lower part of the tile with your right index finger. If the sound is clear and pleasant, it is very OK. If the sound is dull and turbid, it is certainly not good.

3. Drops: Drop colored water droplets (such as ink) on the front of the tile, let it sit for a minute and then wipe it with a damp cloth. If there are traces on the tile surface, it means that dirt has been sucked into the tile; such as If the brick surface is still as bright as a mirror, it means that the tiles do not absorb dirt, are easy to clean, and are of high quality.

4. Quantity: The higher the accuracy of the side length of the ceramic tiles, the better the effect after paving. Buying high-quality ceramic tiles is not only easier to construct, but also saves man-hours and auxiliary materials. Use a tape measure to measure the size of each tile and see if there is any difference around it. The highest accuracy is the best.

5. Scratching: Ceramic tiles have good hardness, strong toughness and are not easily broken. Scratch each other with the edges and corners of the tile fragments to see whether the broken fragments are dense or loose, whether they are brittle and hard or loose and soft, whether they leave scratches or scattered powder. If it is the former, it is good and the latter is bad.

How to identify the quality of ceramic tiles when purchasing

1. Take any number of bricks from the box and check the surface of the bricks Whether it is bright and deformed, and defects such as missing corners, missing edges, missing glaze, holes, spots, etc. are not allowed

2. Take four or more ceramic tiles and place them on a flat surface to see if the color of the tiles is Consistent, check whether the pattern is complete; look a little further to see whether the overall effect is ideal.

3. Take two or more ceramic tiles and place them on the glass surface to see if the tile surface is flat; press the opposite corners of the tiles with your hands to see if there are warped edges; look at the gaps, the smaller the better.

4. Touch two bricks and listen to see if the sound is crisp and loud. If there are any abnormalities, it means that there are cracks in the tiles or there is air remaining in the tiles during the sintering process.

5. Buy the required tiles at one time to avoid color difference.

6. Eliminate tiles whose size does not meet the requirements.
