The company has invested heavily in introducing 12 advanced automatic production lines, with a daily production capacity of 180000 square meters. Chen Di ceramics' eclectic scientific application concept and product creative thinking, from the perspective of market influence, Chen Di ceramic tiles are OK, belonging to the second-tier better brand in eastern Guangdong, with high, middle and low grades.
Code for quality inspection of ceramic tiles
1, the water absorption rate of ceramic tile refers to the percentage of the product weight that is as thin as water after the opening of the product is filled with water, which can directly explain the density of the product and affect the dirt resistance of the product. If the tile absorbs water quickly, it means that the quality of the tile is poor. The actual effect of 10-20% water absorption is that a cup of 150 ml water is poured behind the tile, and after 3 seconds, all the water will penetrate into the brick body.
2. Error detection of tile length and width. The length and width of ceramic tile refers to the error between the actual length and width of the product and the standard length and width of the product. Where e refers to the upper limit error of the same model 10 brick, and f refers to the average error of the same model 10 brick. If ordinary consumers want to judge the length and width error of tiles, they can measure four tiles of the same type with a box ruler. If the length and width of the four tiles are basically equal, it means that the tiles are qualified.
3. Right-angle test. The deformation degree of tile corner relative to the standard right angle is expressed as%, which will directly affect the tile paving effect. After professional calculation, if the result is between 89.5 and 90.5 degrees, it is a qualified product. If ordinary consumers want to judge the right angle of tiles, they can measure the diagonal of tiles with a box ruler. If the two diagonal lines are equal in length, it means that the four corners of the tile are right angles.
4. Surface smoothness. Smoothness is the general term for central curvature and warping. Among them, the central curvature refers to the distance that the central point deviates from the plane when three of the four corners of the tile are on the same plane. Warp refers to the distance that the fourth corner of the tile deviates from a plane when the three corners are on the same plane. Where is the mistake? The qualified products are within 0.5%. When purchasing tiles, ordinary consumers can put two tiles of the same model in front of each other, then fold them in half with ordinary 157g coated paper and insert them into the gap. If they can easily enter, it means that the flatness of the tiles is defective.
5. Wear resistance inspection. The wear resistance of ceramic tiles is divided into five degrees, from low to high. Five degrees belong to super wear resistance and are generally not used for home improvement. Bricks for home improvement can be selected between one degree and four degrees. The state has no clear regulations on the wear resistance of ceramic tiles. Consumers can scrape tiles with sharp objects when buying tiles to see if there are scratches. If there are scratches, it means that poor glazing will make people easy to slip and polish, and the dirty surface of ceramic tiles will not be cleaned.
Above, we mainly studied the quality inspection specifications of ceramic tiles. For ordinary consumers, some terms may be difficult to understand, but for several important quality inspections, everyone should master specific methods. Let's talk about the brand again. It doesn't matter which brand Chen Di tiles belong to. When buying, you still need to do detailed testing and inspection, so as to ensure the quality of tiles.
