When decorating the toilet, if you want to buy a satisfactory glazed tile for the interior wall, it is recommended to make a scientific choice from five aspects: check, look, listen, try and compare.
1. Check whether there is the name and address of the manufacturer, as well as the product name, specification, grade, quantity, trademark, production date and the standards to be implemented on the product packaging box. Check whether there is a factory certificate, whether the products are damaged, and whether the quantity and quality of the products in the box are consistent with the contents on the packaging box.
Second, the glazed surface of ceramic tiles of * * * should be smooth, delicate, shiny and bright, and the matt glaze should be soft and comfortable. Under sufficient natural light or fluorescent lamp illumination, the brick shall be placed at a distance of 1 m for vertical observation, and no obvious glaze defects shall be seen, and the product shall have no color difference. The pattern of patterned bricks shall be clear and fine, and there shall be no obvious defects such as lack of color, broken line, dislocation, etc. The size deviation of good products is small, so a batch of products can be vertically placed on a plane to see if there is any irregularity; Look at the flatness of the bricks. The ceramic tiles can be placed flat on the plane and observed directly with naked eyes. The ceramic tile plane is not warped, and the straight side of the tile is measured with a ruler without gaps. In this way, the product is free of deformation and high regularity, and the construction is convenient. The tile surface is flat and beautiful after paving.
Three tins. You can knock ceramic tiles gently and listen carefully to their sound. For products with good quality, the clear sound indicates that ceramic tiles have high porcelain density and hardness, * * *. Poor quality products will make an "empty" sound when knocked.
Four trials: ceramic glazed tiles with low water absorption should be selected to measure the water absorption of ceramic tiles. The lower the water absorption, the higher the internal stability of ceramic tiles, and the more suitable the space with high moisture or water content (such as toilet and kitchen), without black spots and other problems*** A simple detection method is to pour a glass of water on the back of the ceramic tile. The rapid diffusion of water stains indicates that the water absorption rate is on the high side. On the contrary, it is low. The slower the water absorption rate is, the smaller the water absorption rate is, the better the internal quality is, and the better the product durability is.
Five comparisons, we must shop around and compare the quality within one comparison. Ceramic tiles of the same specification have low water absorption due to their heavy weight and good internal quality. After a certain understanding of the product, we will make a comprehensive comparison of the brand, quality, price, service and other aspects of the product before determining how to purchase
