The white marble stone is pure and white, and it is also used to carve Buddha statues and decorate houses. The West has used white marble as a portrait carving material since the ancient Greek times.
Since ancient China, this kind of stone has been used to make stone steps and guardrails in palaces. The Huabiao in front of Tiananmen, the Jinshui Bridge, the palace pedestal, stone steps and guardrails in the palace are all made of white marble.
Judging from historical data, the mining of marble can be traced back to at least before Nanzhao in the Tang Dynasty. The Three Pagodas of Chongsheng Temple in Dali, built more than a thousand years ago in the Tang Dynasty, have been built with exquisite marble carvings, and have high craftsmanship. Level. The historical palace tombs, such as the Forbidden City in Beijing and the Ming Tombs, have used Yunnan marble in large quantities. Before the 1950s, the mining and processing of marble remained in the way of manual production, until the marble factory was built in 1953, which gradually realized mechanized production, increased the variety of products, and continuously improved the craftsmanship. Its products, in addition to domestic needs, are also exported to Southeast Asia and Arab markets.
Material reference parameters are: whiteness, gloss, compressive strength, flexural strength, Shore hardness, water absorption, density and so on. It is generally believed that it is a sedimentary metamorphic deposit formed under the influence of magmatic hydrothermal fluids, resulting in different degrees of hydrothermal metamorphism and dynamic metamorphism in carbonate formations. Since ancient China, this kind of stone has been used to make stone steps and guardrails in palaces. The Huabiao in front of Tiananmen, the Jinshui Bridge, the palace pedestal, stone steps and guardrails in the palace are all made of white marble. The main component of white marble is calcium carbonate, which is a compound with a chemical formula of CaCO3, mainly composed of CaCO3, MgCO3 and SiO2, and also contains a small amount of Al2O3, Fe2O3 and other components. The fine-grained marble is white in color and hard in quality, making it an excellent material for construction and carving. Basically it is not soluble in water. It can exist in the following forms: aragonite, calcite, chalk, limestone, marble, travertine. Found in rocks. The main component of animal back shell and snail shell. At the same time, it is also an important building material. White marble is hard and white
The advantages of white marble:
1. Not deformed
After a long period of natural aging, the structure of the rock is very uniform, the coefficient of linear expansion is extremely small, and the internal stress will completely disappear.
2. High hardness
Good rigidity, high hardness, strong wear resistance, and small temperature deformation.
3. Long service life
No need to apply oil, not easy to stick to fine dust, maintenance, maintenance is very convenient and simple.
4. No scratches
It will not be blocked by constant temperature conditions, and can maintain its original physical properties at room temperature.
5. Not magnetized
It can move smoothly, without stagnation and astringency, and will not be affected by moisture, and the plane weighing performance is excellent.
