1. Inspection label: The product packaging box shall be marked with the name, address, product name, after-sales service telephone number, specification, quantity, trademark, production date and implementation standard. When buying ceramic tiles, it is necessary to check whether there is 3C certification mark. For the tiles designed and decorated in the interior, it is advisable to choose products with radionuclide meeting the requirements of Class A..
2. Look at the appearance carefully: the glazed surface of high-quality tiles should be smooth and delicate, the glossy glaze should be crystal clear and shiny, and the matte glaze should be soft and comfortable. When the brick is placed at a distance of 1 m, no obvious glaze defects should be seen under sufficient natural light or fluorescent light. Patterned tiles should be delicate and realistic, without obvious defects such as lack of color, broken line and dislocation. The back shading and trademarks of high-quality ceramic products are clear and complete, and there are basically no glaze marks and defects.
3. Splicing effect: Good tiles usually have a small size deviation. Users can put a batch of products vertically on a plane to see if there are any irregularities. Look at the flatness again, and press the edges of two bricks together to see if there are any gaps. Good products will not deform basically, and the brick surface will be smooth and beautiful after paving. In addition, users can also look at the color difference of the product, put a few bricks together and look carefully under sufficient light. For products with different shades, the overall effect after paving is not good.
4. Click to listen: Users can tap the tiles and listen to their sounds carefully. The sound of products with better quality is crisp and pleasant. Inferior products have short firing cycle and low firing temperature due to improper use of raw material formula, and will make an "empty" sound when knocking.
5. Weighing: Weigh the tiles. Usually, tiles with the same specifications have low water absorption and better internal quality.
6. Comparison of varieties: floor tiles are divided into glazed floor tiles and unglazed floor tiles according to glaze conditions. Glazed floor tiles are mainly used for floor decoration in bathrooms and kitchens, and are used in conjunction with interior wall tiles. Floor tiles become polished tiles after surface polishing. If the water absorption of polished brick is less than 0. 1%, it is also called vitrified brick. Polished tiles have a mirror-like surface and are high-grade ceramic products.
7. Tile corners: When laying tiles, many consumers and workers have encountered the problem that the corners are difficult to align, which shows that the flatness of tiles may not be consistent. When selecting tiles, the user randomly selects several tiles and looks along the edge and diagonal of the tiles with his eyes. If there is a phenomenon of "edge warping", it means that the flatness of the tile is not enough. If not, it means that the flatness of tiles is basically qualified, which is also a small skill in choosing tiles.
