There are two types of marble table and fireproof board. Today we have to understand what the marble table needs to pay attention to.
First, choose the grade: according to the size of the allowable deviations, flatness and angle allowable tolerances, as well as the appearance of quality, surface finish and other indicators, marble plate is divided into superior products, first-class products and qualified products of three grades; marble plate Grading, identification is mainly through the detection of instruments, measuring instruments to identify.
Second, check the appearance quality: the appearance of different grades of marble plate is different. Because marble is naturally formed, defects are inevitable. At the same time, the pros and cons of processing equipment and measuring tools are also the causes of sheet defects. Some plates are not full (warped or sag), plates have defects (cracks, blisters, stains, etc.), plate body specifications (such as lack of edges and corners, the body is not correct) and so on. According to national standards, all grades of marble slabs are allowed to have certain defects, but superior products are not so obvious.
Third, the choice of pattern color: marble plate colorful, varied colors, patterns are not the same, this is the marble plate valuable charm lies. The color tone is basically the same, the color difference is small, and the beautiful pattern is a concrete expression of the fine variety, otherwise it will seriously affect the decorative effect.
Fourth, the detection of surface gloss: the level of marble surface gloss will greatly affect the decorative effect. In general, the polished surface of a high-quality marble plate should have a mirror-like gloss and clearly reflect the scenery. However, due to the different chemical compositions of marbles of different qualities, the difference in glossiness will be great even for products of the same grade. Of course, the surface gloss of the board between different grades of the same material will also have some differences. In addition, the strength and water absorption of marble plates are also important indicators for evaluating marble quality.
