How to distinguish anti-counterfeiting of Yu Hui tiles? Is it made in Guangdong? In recent years, various brands and types of ceramic tile products emerge in an endless stream, and consumers are easily dazzled and confused when purchasing. In fact, it is not difficult to choose a suitable product as long as you grasp the main points. Steps/methods 1 depending on the grade identification. Ceramic tiles are divided into five grades, first-class, second-class, third-class and off-grade. As the prices vary greatly, we need to compare them carefully. In addition, when purchasing, we should also pay attention to whether the signs, specifications and color numbers on the tiles and the packaging boxes are consistent, and whether the product certificate, trademark and quality inspection label are clear. 2 Look at the size of the specifications, which is not only conducive to construction, but also reflects the decorative effect. Good specification deviation is small, uniform after paving, straight brick joints and good decorative effect. Products with dimensional error greater than 0.5 mm and flatness greater than 0. 1 mm will not increase the construction difficulty, and the effect after decoration will be poor. Whether the size is up to standard can be judged by the target. Put the brick on the plane and see if its four sides are completely consistent with the plane, and at the same time see if the four corners of the tile are at right angles. It is good to report that there are no defects such as concave-convex, bulging, warping, etc., and the error of side length is not more than 0.2-0.3mm, and the error of thickness is not more than 0.1mm. The higher the accuracy of the side length of ceramic tile, the better the effect after paving. Buying high-quality tiles is not only convenient for construction, but also saves working hours and accessories. Measure the size and periphery of each tile with a tape measure, and the one with high accuracy is the top grade. Hardness ceramic tile is the top grade with good hardness, strong toughness and non-fragile. Scrape each other with the edges and corners of tile fragments to see whether the broken fragments are fine or loose, brittle or soft, leaving scratches or loose powder. If the former is top grade, the latter is poor quality. Whether the size is standard or not is the key to judge the quality of ceramic tiles. Use a tape measure or caliper to measure whether the diagonal and four sides of the tile are consistent in size and thickness. A good ceramic tile has a crisp sound, indicating a high porcelain content. If the sound is "click" and stubble breaks, it means that there is a crack in the brick. Good tiles are easy to be installed by the master, and the installed effect is standardized. 4. The tiles with good patterns have clear and consistent patterns, exquisite workmanship, and no obvious color leakage, dislocation, broken line or inconsistent depth. 5 The color difference of color-difference tiles is directly related to the decoration effect. Not a batch of products, or the same batch may produce color difference. Therefore, in the process of purchasing, it is necessary to sample and compare each packaged product, put the tiles in the same variety and model of bricks, and observe the degree of color difference. Good products have little color difference, the colors between products are basically the same, the colors are bright and even, and they are radiant, while poor products have large color difference and different shades. The color of ceramic tiles should be uniform, the surface smoothness and flatness should be better, the periphery should be regular and the pattern should be complete. Take out four or five pieces from a box to see if there are any defects such as color difference, deformation and lack of edges and corners. 6 Listen to the sound and tap with a hard object. The crisper the sound, the higher the porcelain degree and the better the quality. You can also hold a corner of the tile with your left thumb, forefinger and middle finger and hang it down easily. Tap the middle and lower part of the tile with the index finger of your right hand. If the sound is crisp and pleasant, it is the top grade; if the sound is dull and stagnant, it is the inferior grade. 7. The water drop test can drop water on the back of the tile to see seepage velocity after the water is dispersed. Generally speaking, the slower the water absorption, the greater the density of tiles; On the contrary, the faster the water absorption, the rarer the density and the better the internal quality. Yu Hui ceramic tile has clear and consistent patterns and colors, exquisite workmanship, no obvious color leakage, strong toughness and no scratches. If you don't believe it, you can try it according to the above method!
