Carefully choose to buy healthy and safe tiles

According to industry experts, good quality ceramic tiles generally pay more attention to safety. Radiation will also be controlled within the limits allowed by the state. When buying ceramic tiles, it is necessary to check multiple ways rather than just look at the style of single products.

â—ŽInspection label: The product packaging box should have the name of the factory, the address of the factory, the name of the product, the telephone number of the after-sales service, the specifications, the quantity, the trademark, the date of manufacture and the standards implemented. For the porcelain bricks, the CCC certification mark must be inspected. For ceramic tiles, products with radionuclides that meet Class A requirements should be selected.

â—Ž Look at the appearance: the quality of the tile glaze should be smooth and delicate, the gloss glaze is crystal clear, and the matt glaze is soft and comfortable. Under sufficient natural light or fluorescent lighting, the bricks should be placed vertically at a distance of 1 m and no obvious glazed defects should be visible. The pattern of the pattern of bricks should be delicate and realistic, without obvious defects such as lack of color, broken lines and misalignment. The shading and trademark of the back of the high quality ceramic products are clear and complete, with little glaze or defects.

â—Ž splicing effect: good ceramic tile size deviation is small, put a batch of products vertically on a plane to see if there is any jagged phenomenon. Looking at the level of flatness, the edges of the two bricks can be pressed together to see if there are any gaps. Good product deformation is small, and the brick surface is flat and beautiful after paving. Look at the color difference of the product, put a few pieces of brick together and carefully look at the light, the products with different shades between the products, the overall effect is poor after the paving.

◎ Percussion: Listen gently to the tile and listen to its sound. The better quality product sounds crisp and sweet. Poor quality products are due to improper formulation of raw materials, short firing cycle, low firing temperature, and an “empty” sound when struck.

â—ŽComparative varieties: Floor tiles are divided into glazed floor tiles and unglazed floor tiles according to the glazed condition. Glazed floor tiles are mainly used for floor decoration of bathrooms and kitchens, and are used together with interior wall tiles. Most of the floor tiles are polished to a polished surface. Most polished tiles have a water absorption of less than 0.1%, also known as vitrified tiles. The polished surface of the polished brick is a high-grade ceramic product.

◎ Paving effect: When paving tiles, many consumers and workers have encountered difficulties in aligning the corners. This means that the flatness of the tiles may not be too close. When selecting tiles, randomly select a few pieces. The gaze is measured along the edge and diagonal of the tile. If there is a phenomenon of “warping”, it means that the flatness of the tile is not enough. If not, it means that the flatness of the tile is basically clear. This is also an optional tile. Tips.
