Marble cabinet countertops are recognized by the high-end market for their elegant natural texture, but there are always many consumers who hesitate because of the radiation problem of marble and the identification method. These problems will naturally be solved after reading this article.
Marble, also known as marble, is a recrystallized limestone whose main component is CaCO3. Limestone softens under high temperature and pressure and recrystallizes to form marble when the minerals in it change. It is mainly used for processing into various shapes and plates and used as the wall, floor, platform, and pillar of the building. It is also commonly used as the material of monumental buildings such as monuments, towers, and statues.
Marble originally refers to the white limestone with black patterns produced in Dali, Yunnan Province. The section can form a natural ink landscape painting. In ancient times, marble with shaped patterns was often used to make painting screens or mosaic paintings. Later, the name marble countertop gradually It has been developed to refer to all kinds of limestone that have various colors and patterns and are used as building decoration materials. White marble is generally called white marble, but white marble for statues made in the West is also called marble.
How to identify marble countertops:
For processed finished marble countertops, the quality can be distinguished from the following four aspects: At first glance, the surface structure of the stone is observed with the naked eye. Generally speaking, the uniform fine material structure of the stone has a fine texture, which is the best product of the stone; the coarse-grained and unequal-grained structure of the stone has a poor appearance effect. In addition, due to the influence of geological effects, the stone often produces some small cracks in it. The stone is most likely to break along these parts, so care should be taken to remove it. As for the lack of edges and corners, it affects the appearance, so you should pay special attention to it when choosing. The second quantity is to measure the size and specifications of the stone, so as not to affect the splicing, or cause the patterns, patterns, and lines after the splicing to be deformed, and affect the decorative effect. Listen three times, that is, listen to the percussion of the stone.
The editor of China Cabinet Network reminds you that the percussion sound of a good-quality stone is clear and pleasant; on the contrary, if there are slight cracks in the stone or the contact between the particles becomes loose due to weathering, the percussion sound will be rough. Four tests, that is, use a simple test method to test the quality of the stone. Usually, a small drop of ink is dropped on the back of the stone. If the ink is quickly dispersed and leached, it means that the particles inside the stone are loose or there are gaps, and the quality of the stone is not good. On the contrary, if the ink drops stay in place, the stone is of good quality.
The characteristics and advantages of marble countertops:
1. No deformation, high hardness, strong wear resistance. After long-term natural aging, the structure of the rock is uniform, the linear expansion coefficient is extremely small, the internal stress disappears completely, and it is not deformed. It is not afraid of acid, alkaline liquids, corrosion, no rust, no need to apply oil, not easy to stick to dust, convenient and simple maintenance, and long service life.
2. Anti-abrasion, high-temperature resistance, and maintenance-free. Good rigidity, high hardness, strong wear resistance, low-temperature deformation. There will be no scratches, it is not blocked by constant temperature conditions, and its original physical properties can be maintained at room temperature.
3. Physically stable, well-structured, impacted grains fall off, the surface does not have burrs, does not affect the plane accuracy, the material is stable, can ensure long-term non-deformation, the linear expansion coefficient is small, the mechanical accuracy is high, rust-proof, anti-magnetic, and insulation. It is not magnetized, can move smoothly during measurement, has no sense of stagnation, is not affected by moisture, and the plane is weighed well.
