The vitrified bricks are bright and clean, and they look generous and beautiful after the paving. The price is moderate and easy to clean. However, it also has the disadvantage that it has a certain permeability. When colored stains (such as ink) are dropped, it must be wiped quickly, or it will infiltrate to leave a mark. For a long time, more than one has become a flower. However, good quality vitrified tiles are better resistant to penetration. This is a feature of vitrified bricks that are less than glazed tiles. Selection techniques for high quality vitrified tiles 1) Collect relevant information in various ways through various channels. Such as: friends introduction, online collection and other methods. 2) Visit the market in person. This is necessary because it gives a more intuitive understanding of the performance price of the product. Personally recommend to choose some well-known brands or strong businesses to buy. Because the brand and strength are also the guarantee of product quality and good after-sales service! 3) The quality of the vitrified brick is simple and easy to distinguish: You can choose by a few simple methods: “Look, sing, listen, measure, tryâ€! A look: mainly to see whether the polished brick vitrified brick / polished tile surface is shiny, with or without scratches, stains, leaking, missing, missing, missing feet and other defects. Look at the bottom mark of the embryo. The bottom of the product produced by the regular manufacturer has a clear product mark. If it is not or is particularly blurred, it is recommended to be careful! Second 掂: It is the test feeling, the same specification product, good quality, high density brick feel is relatively heavy, on the contrary, the quality of the product feels lighter. Listening to the tile: If the sound is thick and the sound is long and the sound of the echo is as long as the sound of the bronze bell, the degree of porcelain is high, the wear resistance is strong, the bending strength is high, the water absorption rate is low, and it is not easily contaminated. The degree of porcelain is low (even cracks exist), the wear resistance is poor, the bending strength is low, the water absorption rate is high, and it is highly susceptible to contamination. Four quantities: the length deviation of the polished brick is ≤1mm, the deviation of the foot line is 500×500 products ≤1.5mm, the 600×600 product ≤2mm, the 800×800 product ≤2.2mm, if it exceeds this standard, it will be for you. The decorative effect has a big impact. The best way to measure the size of the diagonal is to straighten the diagonal line with a very thin line to see if there is a deviation. Five tests: First, try the shop, randomly sample a number of products in different boxes in the same model and the same color number, try to shop on the ground, stand 3 meters and observe carefully, check whether the product color difference is obvious, brick and brick Whether the gap is straight and the chamfer is uniform; the second is to test the foot feeling, see if the slip is not slippery, pay attention to whether the test brick is non-slip and not add water, because the more water will be more crappy. 4) Precautions during acceptance: a. The packaging of the regular manufacturer is clearly marked with the name of the factory, the address, the trademark, the specification, the grade, the color number, the work number or the production batch number, etc., and has clear instructions for use and implementation standards. b. The polished bricks of regular manufacturers have clear trademarks or logos. c. When you make a brand selection and find that the above marks or marks are not complete, please be careful to do so. If necessary, you can go to the local industry and commerce or quality supervision department for identification. d. The identification of product quality can also be identified according to the steps of “look, slap, listen, measure, testâ€.
