Marble is a kind of building stone product widely used in modern times. Due to its natural appearance and color, marble is more and more popular among modern people, especially in the interior decoration process, using marble, not only its decorative effect. Good, and its wear resistance is good, and its anti-fouling ability is strong; but due to the market competition, many stone enterprises are constantly filling the stone market with the inferior marble produced by them, and as a consumer how to carry out the marble materials on the market. What is the quality? How to judge the true and false? 1. Eye view: The stone with uniform fine structure has fine texture and is the best for stone; the stone with coarse grain and unequal grain structure has poor appearance. 2, ear hearing: good quality stone knocking sound is crisp and sweet; if there is a slight crack inside the stone or due to weathering, the contact between the particles becomes loose, then the knocking sound is rough. 3, dripping ink: a small amount of ink is dropped on the back side of the stone, such as the ink is quickly dispersed and leached everywhere, which means that the inner particles of the stone are loose or there are gaps, the quality of the stone is not good; if the ink drops in place, it means the stone material Well, because of its relatively high density, good compactness and low water absorption, it will be more moisture-proof during use and the service life will last for a long time. In addition, it is recommended that consumers ask the manufacturer to produce the inspection report when purchasing the stone, and should pay attention to the date of the inspection report. The stone of the same variety has different radioactivity due to the difference of its ore point, ore layer and place of origin, so it is selected or used.
