Modern urban life is busy and tense, and a warm home can bring everyone the most relaxing leisure time. But how can you make your home warm and comfortable? With a little skill, you can easily create a pleasant home. Jiuzheng Building Materials Co., Ltd. has prepared a series of fashion information from house decoration to home decoration to help you have a relaxed and comfortable life. Place the tiles in a well-lit area for appearance quality identification: 1 size deviation size. Take a brick to measure whether its side length meets the requirements, then take several bricks stacked together, compare the size of the same, the large size error will not only increase the difficulty of construction, but also affect the effect after decoration. Small brick deviations are allowed at ±1 mm and large bricks are allowed at ±2 mm. 2 deformation size. Take two bricks side by side, depending on whether the side seams are small and straight, but the side straightness is good; then the two bricks are buckled together to see if the gap is small and straight, and the flatness is good. Look at the side of the tile for unevenness. The front side is flat and slightly convex. If the warpage is serious, it will affect the firmness of the tile in the future. The dimensional deviation and deformation size determine the size, straightness and flatness of the decorative surface of the tile. Note: The size of the different types of mixed paving, accessory bricks, waistline bricks and main bricks should be matched. 3 color difference size. Because the number of wall tiles purchased at one time is large, if there is obvious color difference between multiple packages, the decoration effect is very affected. It is necessary to sample and compare all the packaged products, observe the change of color difference, and the color difference can not be selected. 4 surface quality. Observe whether the brick surface is fine and even, and observe whether the product has obvious quality defects such as glaze, spots, cracks, glaze bubbles, corrugations, etc., and the above defects are absolutely unselectable. Then, use a few drops of colored liquid to spread on the surface of the surface. After a few seconds, dry it with a damp cloth to observe whether the surface has residual color points. The color point indicates that there are many pinholes, it is easy to hang dirty, and the quality of the glaze is not high. Can not be removed, indicating that the brick has a large water absorption rate and poor anti-staining ability. Intrinsic quality judgment 1 knock. Use a thin stick to gently knock (or use a finger to knock) the suspended tiles. The sound is crisp and the tiles are crack-free, the degree of sintering is good, and the strength is high. If the sound is boring, there may be heavy skin or cracks in the tile: heavy leather When the brick is formed, the air in the material is not discharged, resulting in poor bonding between the material and the material, and internal cracking, which cannot be seen from the surface, and can only be identified by listening to the sound. 2 handcuffs. The quality of the ceramic tile components are relatively heavy and relatively real. This is mainly due to the choice and proportion of raw materials. The better the mechanical pressure of the ceramic tile during processing, the heavier the weight. 3 drops of water. Drop a few drops of water on the back of the tile to observe the absorption speed, the faster the absorption, the greater the water absorption rate. In general, products with low water absorption, good sintering degree, high strength, good frost resistance and good product quality. 4 scraping. Scratch the tile glaze with sharp objects. If there are scratches, it means that the glaze is easy to slip, and after the glaze on the surface is polished, the brick surface will not be cleaned. Of course, the identification of technical performance can not be based solely on the feeling, but also must look at the recently valid quality inspection report certificate provided by the manufacturer with the CMA chapter, and the products that meet the technical standards have the certificate issued by the state.
