How to judge the quality of ceramic tiles
? I believe that many of my friends found that some of the tiles had been cracked after they bought the tiles for a while, so today the editor of ceramics will tell you how to look at the quality of the tiles. 1. Look at the brand and grade identification of well-known brand wall and floor tiles, the quality meets the national standard, and the harmful substance content is within the safe range. At the same time, ceramic tiles are divided into five grades. There are differences between superior, first, second, third and qualified products. Because of the large price difference, careful comparison is required. In addition, when purchasing, pay attention to whether the brand logos, specifications, and color numbers on the ceramic tiles are consistent with those on the packaging box, and whether the product certification, trademark, and quality inspection standards are clear. 2. Look at the size of the specifications, not only conducive to the construction, but also can reflect the decorative effect. Good specifications have small deviations, neat after paving, straight outdoor wood deck tiles seams, and good decorative effects. Take two pieces back-to-back and face-to-face to see if they can be in close contact. If there is a phenomenon of excessively large gaps, it can be judged whether there is warping. The higher the accuracy of the side length of the tiles, the better the effect after paving. Buying high-quality tiles is not only easy to construct, but also saves man-hours and auxiliary materials. Use a tape measure to measure whether there is any difference in the size and periphery of each tile. The one with high accuracy is the top grade. 3. Hardness ceramic tiles are top grade with good hardness, strong toughness and not easy to break. Scratch each other with the edges and corners of the fragments of the tiles, check whether the broken fragments are fine or loose, whether they are hard, brittle or soft, whether they leave scratches, or are scattered powder. If the former is the top grade, the latter is the quality. difference. Whether the size is standard is the key to judging the quality of the tiles. Use a tape measure or caliper to measure whether the diagonal and four sides of the tiles are uniform in size and thickness. A good tile has a crisp sound, indicating that the porcelain content is high. If the sound 'click' with stubble, it means that there are cracks in the outdoor wood deck tiles. 4. The pattern and color of the pattern are clear and consistent, and the craftsmanship is delicate and exquisite. There is no obvious color leakage, dislocation, disconnection or inconsistent depth. The color difference of color difference tiles is directly related to the decoration effect. It is not a batch of products, or the same batch may produce color difference. Therefore, during the purchase process, each packaged product must be sampled and compared, and the tiles are placed Observe the degree of color difference among bricks of the same variety and the same model. Good products have very little color difference. The colors of the products are basically the same, the color is bright and uniform, and the color is radiant, while the poor products have a large color difference, and the color of the product is different. The color of the tiles should be uniform, the surface finish and flatness should be good, the periphery is regular, and the pattern is complete. Take out four or five pieces from a box to see if there are any defects such as color difference, deformation, lack of edges and corners. 6. Tap with a hard object to listen to the sound , The clearer the sound, the higher the degree of porcelain and the better the quality. You can also clamp the corner of the tile with your left thumb, index finger, and middle finger, and hang it down easily. Tap the middle and lower part of the tile with your right index finger. Dull and turbidity are inferior products. 7. The drip test can put water droplets on the back of the tile to see how fast the water is infiltrated after the water is dispersed. Generally speaking, the slower the water absorption, the greater the density of the tile; on the contrary, the faster the water absorption, the density Sparse, its inherent quality is better than the former. 8. Anti-fouling. Look for ink and apply it to the surface for 1 hour and then scrub to see if there are any traces. If there is no trace, the anti-fouling power is strong. If there is infiltration, the anti-fouling is poor. The editor of Ceramics brings you an article on how to read the quality of ceramic tiles. I hope that you can read about these aspects when you go to buy ceramic tiles after reading this article.
