Natural stone board is a kind of stone board with natural stone as raw material. We have strong appearance after processing. This kind of board is the most basic stone in the building decoration industry. When we process this kind of stone board, we need to judge the specific processing method of the stone according to the type of stone. Here we will talk about the processing of stone slabs with Xiaobian. 1. Natural Marble : Marble is named after Dali City, Yunnan Province, which produces such stone. Its main chemical composition is carbonate, which is a type of metamorphic rock formed by the deposition of limestone, dolomite and other rocks through high temperature and pressure in the earth's crust. The marble minerals are extremely rich, with a wide variety of products, and are produced all over the country. According to incomplete statistics, there are more than 400 varieties. In marble, red, yellow, brown, black, and green are present due to iron oxides, mica, and graphite. The texture is beautiful and elegant after polishing, people often named according to their place of production and color. Such as white (Beijing) Fangshan Hanbaiyu, Dali Cangshan white; black Guilin black, two peaks black; red Sichuan Jiangnan red, northeastern red; colored marble flowers have "spring flowers", "autumn flowers", "ink flowers" Three varieties, it is a unique boutique in Yunnan marble. Each piece of natural marble has a unique natural pattern and color. The high-quality marble furniture will use a single piece of stone material to match the ratio of materials in different parts. A good marble will have a large area of ​​natural lines at its main site, while the leftovers will be used to embellish the back and stigma. In the case of inferior furniture, scrap is used when preparing the material, and the surface is not changed. Artificial marble is made of natural marble or gravel as the filler, cement, gypsum and unsaturated polyester resin as binders, and is made by stirring, grinding and polishing. Artificial marble has poor transparency and no gloss. There is a simpler way to identify artificial and natural marble: a few drops of dilute hydrochloric acid, natural marble is strongly foamed, and artificial marble is weak or even non-foaming. After natural marble is laid, it is necessary to take measures to reduce pollution by reducing the pollution. In general, the half-life of harmful radon is only 3.2 days, and the indoor radon concentration can be reduced to outdoor level after 20 to 30 minutes after opening the door. Therefore, the easiest way is to increase ventilation. The room that has just been renovated is best to be tested. If the test results are not qualified, you can use radiation-reducing paint or install lead-free protective plates to prevent the release of cesium from building materials. If the radioactive index is too high, the stone must be replaced immediately. 2. Natural granite : Its main mineral composition is feldspar, quartz and mica. Its dense structure, small pores, with wear-resistant, antifreeze, anti-weathering corrosion and so on. Marble in the air will soon react with the water and carbides in the air. It will lose its luster and become rough, while granite has strong weather resistance and can be decorated both indoors and outdoors. There are many kinds of granites. China's Fujian, Shandong, Inner Mongolia, Xinjiang, Sichuan, Jiangxi, and Guangdong provinces are the origins of granite. In recent years, there have been many types of granite imported from abroad. Granite is also based on Named after the place of production and pattern tone, such as: "Jinan blue granite." According to the processing type, granite can also be divided into “Axe Axe Plate, Rough Grinding Plate, Polished Plate, Buckle Planing Plate, Burning Plate, etc. Their surface roughness is different, and they are suitable for different environmental renovations, and most interior decoration uses. Polished board.Artificial marble is divided into marble and artificial granite. Natural granite is igneous rock, also called acid crystal deep diagenetic rock. It is the most widely distributed type of rock in igneous rock and belongs to hard stone. It consists of feldspar, quartz and mica. Its composition is mainly silica, accounting for about 65%. ? 75%. The rock is hard and dense, and can be divided into three kinds of "Pie-crystal", "Crystalline" and "Fine-grained" according to the size of the crystal grains. The quality of granite depends on the composition and structure of the mineral. The fine granite has fine and uniform crystalline particles, less mica content and more quartz, and does not contain pyrite. Granite is not easy weathering and deterioration, the appearance of color can be maintained for more than a century, it is mostly used for wall base and exterior wall finishes. As granite has higher hardness and wear resistance, it is also commonly used in high-grade building renovation projects. The above is the introduction of knowledge about stone plate processing in Xiaobian. Please pay attention to Qijia information for more practical knowledge.
