1. inspection label: the product packaging box should contain the name, address, product name, after-sales service telephone number, specifications, quantity, trademark, production date and implementation standards. For ceramic tiles, CCC certification mark should be checked, and the ceramic tiles for interior design and decoration should be selected with products meeting Grade A requirements.
2. Look at the appearance carefully: the glaze of high-quality tiles should be smooth and delicate, the luster 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. Pattern brick pattern should be delicate and realistic, without obvious defects such as lack of color, broken line and dislocation. The shading and trademarks on the back of high-quality ceramic products are clear and complete, with few glaze marks or defects.
3. Splicing effect: Good tile size deviation is small. Put a batch of products vertically on a plane to see if there is any unevenness. Look at the flatness again, and press the edges of two bricks together to see if there are any gaps. Good products have small deformation, and the brick surface is smooth and beautiful after paving. Look at the color difference of the product, put a few bricks together and look carefully in sufficient light. For products with different shades of color, the overall effect after paving is not good.
4. Tap and listen: Tap the tile and listen to its sound carefully. The sound of products with better quality is crisp and pleasant. Inferior products will make an "empty" sound when knocked because of improper raw material formula, short firing cycle and low firing temperature.
5. Weighing: Weigh the tiles. Generally speaking, tiles of the same specification have low water absorption and good 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. Most floor tiles are polished and become polished tiles. The water absorption of most polished tiles is less than 0. 1%, which is also called vitrified tiles. 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, indicating that the flatness of tiles may not pass. When choosing tiles, randomly select a few pieces and look along the edge and diagonal of the tiles with your eyes. If the phenomenon of "edge warping" is found, it means that the flatness of the tile is not enough. If not, it means that the flatness of tiles has basically passed, which is also a tip for buying tiles.
