Put a drop of ink on the back of the marble. If the ink quickly disperses and leaches everywhere, it means that the particles inside the marble are loose and the quality is poor; but if the ink drops do not penetrate, the marble is dense and the quality is good. This is actually a simple test of the water absorption rate of the marble. If the ink droplets do not penetrate, it may indicate that the texture of the marble is relatively dense and the water absorption rate is low. Marble is generally coated with a protective agent to prevent stains from penetrating. Even if the customer sees that the ink droplets are not penetrating, it is likely that the protective agent is working, not the performance of the marble itself. In addition, if the water on the back of the marble becomes bead-like, it means that it is difficult to absorb water after the protective agent is applied to the marble, and it may not be able to adhere to the cement. Therefore, it can be considered that the lower the water absorption on the front of the marble, the better, but it is also It should be ...

Marble is mainly composed of calcite, limestone, serpentine and dolomite, and its main component is calcium carbonate, which accounts for more than 50%. Others include magnesium carbonate, calcium oxide, manganese oxide and silicon dioxide. Marble is generally soft in nature, which is relative to granite. Of course, you don't need to bother about this, because this geological age is calculated in billions. In our lifetime, this marble qualitative change is a limited change. Marble floor tiles have attracted the attention of consumers with their gorgeous appearance and very practical features. The difference between marble and other architectural stones is that each marble floor tile has a different texture. The marble with clear and curved texture is smooth and delicate, bright and fresh, like a visual feast that brings you time and time again, and is installed in the living room. , Can set off the living room more elegant and generous. Because marble generally contains impurities, and calcium carbonate in the atmosphere is affected by carbon dioxide, carbides, and water vapor, it is also easy to weather and dissolve, and the surface of the marble quickly loses its luster.

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, marbles with shaped patterns were often used to make painting screens or mosaic paintings. Later, the name marble gradually developed to refer to everything with various colors and patterns, and marble was used as limestone for building decoration materials. The white marble is generally referred to as white marble, but the white marble for statues made in the West is also called marble. Regarding the name of the marble, there is a saying-the marble in Dali, my country used to be the best quality. Hence the name.

The marble is very beautiful after polishing. Marble is mainly used for processing into various shapes and plates, as the walls, floors, platforms, and columns of buildings, and is often used as materials for monumental buildings such as monuments, towers, and statues. Marble can also be carved into practical works of art, such as arts and crafts, stationery, lamps, and utensils. According to the classification of marbles, the naming principles are different. Some are named after the place of origin and color, such as Dandong green, Tieling red, etc.; some marbles are named after patterns and colors, such as Snow White and Ai Yeqing; some are named after patterns. Such as autumn scenery and ocean waves; marble has traditional names, such as white marble and crystal ink jade. Therefore, the phenomenon of similar names or different rocks with the same name often appears due to the different origins of marble.

Marble is a metamorphic rock formed by the high temperature and high pressure of the original rocks in the earth's crust. The internal force of the earth's crust promotes the qualitative change of various types of rocks. The change of marble quality refers to the change in the structure, structure and mineral composition of the original rock. The new type of rock formed by the marble qualitative transformation is called metamorphic rock. Marble is mainly composed of calcite, limestone, serpentine and dolomite, and its main component is calcium carbonate, which accounts for more than 50%. Others include magnesium carbonate, calcium oxide, manganese oxide and silicon dioxide. Marble is generally soft in nature, which is relative to granite.

Мермер је генерално мекши у физичким својствима, што је у односу на гранит. У унутрашњој декорацији, мермер је погодан за ТВ плоче, прозорске прагове и унутрашње подове. Мермер је трговачко име, а не петролошка дефиниција. Мермер је главна категорија природног архитектонског украсног камена. Генерално, то се односи на метаморфне или неметаморфне карбонатне стене које имају декоративну функцију и могу се прерађивати у архитектонско камење или рукотворине. Мермер се односи на мермер, кречњак, доломит и скарн и мермер формиран различитим изменама карбонатних стена.

Due to the different applications of natural marble, its industrial technical requirements have different focuses. Natural marblemarble blocks The main requirements of the building materials industry standard (JC202-92) for natural marblemarble blocks are as follows: Marble blocks must have the shape of a right-angled parallelepiped. The size of marble blocks requires a length greater than or equal to 100cm, a width greater than or equal to 50cm, and a height greater than or equal to 70cm. The appearance quality of marble requires that the hue patterns of the same batch of marble blocks should be basically the same; the appearance quality grades such as missing corners, missing edges, and cracks of marble blocks should meet the requirements of Table 4.25.6. The physical performance requirements of marble (JCT202-2001): bulk density is not less than 2.6g/cm3; water absorption is not more than 0.5%; dry compressive strength is not less than 50MPa; bending strength is not less than 7.0MPa.

The construction process of marble's grinding treatment and crystal polishing treatment: First, before refurbishing and polishing the marble, do waterproofing first. The purpose is to make the marble absorb as little water as possible, so as to reduce the water absorption rate of the marble. After 300#, do the waterproofing. At that time, the waterproof effect will be reduced or disappeared because of the grinding. If allowed, it is best to do waterproofing again after 800#. When encountering relatively loose marbles, such as white sand beige, sandstone, tropical rain forest, wood grain stone, etc., first use high-content sealing curing agent (such as super-hard inorganic coating, silicone resin sealant with a content of more than 40%) as pre-treatment. It makes the marble harden the material while filling the looseness.
