With the improvement of people's aesthetic taste, more and more figures of stone have appeared in the construction and decoration materials. Marble is a popular type among many stone types. There are many reasons why marble is so popular, such as beautiful and durable. Marble is formed after a long period of natural aging, uniform structure, not easily deformed, and high hardness, strong wear resistance, therefore, is not easy to scratch. So what are the main components of marble and what are the characteristics and uses of marble? Let's go and see it together.
The main ingredient of marble
1. Marble, also known as marble, is a recrystallized limestone and its main component is CaCO?. Limestone softens at high temperatures and pressures and recrystallizes to form marble when the contained minerals change. The main components are calcium and dolomite, with many colors, usually with obvious patterns and many mineral particles. Mohs hardness between 2.5 and 5. Because marble generally contains impurities, and calcium carbonate in the atmosphere by the role of carbon dioxide, carbides, water, but also easy to weathering and erosion, and make the surface lose luster quickly.
2, marble general physical properties are relatively soft, which is relative to granite. In interior decoration, marble is suitable for use on TV stands, windowsills, and indoor floors. Marble is a trade name, not a petrological definition. Marble is a type of natural building decorative stone, generally refers to a modified or non-metamorphic carbonate rock that can be processed into building stone or handicrafts. It is named after the famous stone with beautiful color and pattern produced by Dang Cang Mountain in Dali, Yunnan, China. Marble refers to skarn and marble formed by different alterations of marble, limestone, dolomite, and carbonate rocks.
Marble classification
Marble is divided into three categories:
Dolomite: Magnesite (calcium carbonate) content more than 40%
Forsterite: The content of magnesite (calcium carbonate) is between 5% and 40%.
Calcite: magnesite (calcium carbonate) content less than 5%
Ore raw material features
(I) Process Classification
Marble is a type of rock represented by marble, including carbonate rocks and related metamorphic rocks. It is generally softer than granite.
Common rocks are marble, limestone, dolomite, skarn and so on. The division of marble varieties, the naming principles are different, some named after the origin and color, such as Dandong green, Tieling red, etc.; some named after the pattern and color, such as snow white, Aiyeqing; some named after the pattern image, such as autumn , waves; some are traditional names, such as white marble, crystal ink jade and so on. Therefore, due to different origins often have the same synonym or different rock with the same phenomenon.
The basic colors of marble produced in China can be divided into seven series: white, yellow, green, gray, red, coffee and black. Each series can be divided into several sub-categories according to the color and pattern characteristics of the polished surface, such as: white marble, rosin yellow, Dandong green, hang grey and so on.
The pattern and grain size of marble vary greatly, including landscapes, clouds, patterns (threads, willows, images, paleontology, etc.), and snowflakes. Modern buildings are colourful and constantly changing. Therefore, marbles for decoration are also required for many varieties and colors, and can be used in different parts of buildings. Generally require monochromatic marble color uniformity;
Caihua marble requires a gradual transition between pattern and depth; pattern-type marble requires clear patterns, vivid colors, and strong pattern regularity. In short, beautiful colors, convenient large-area splicing and decoration, and the ability to supply in batches of colors are all good.
(b) Mineral composition and main features
The mineral composition and ore characteristics of marble are directly related to the performance and decorative effects of its products.
(C) Chemical composition and physical properties
The chemical composition of marble generally does not play a major role in its ability to be used, but it can directly explain the lithology and indirectly affect the physical and chemical properties, and has certain significance for the evaluation of machinability, weathering resistance and corrosion resistance of marble.
The physical property of marble is an important index to judge its machinability, and it is also an important reference for the performance and scope of use.
The characteristics and use of marble
Marble refers to skarn and marble formed by different alterations of marble, limestone, dolomite, and carbonate rocks.
The main consolidating component of the marble is calcium, which is the natural constituent of the marble. Some of the viscous minerals are incorporated into the calcium during stone formation, creating beautiful colors. Viscous minerals are also stains for granite and other natural stone.
The characteristics and advantages of marble are: no deformation, high hardness, long service life, no scratches, no magnetization, etc. The rock is naturally formed over a long period of time, and its structure is uniform and easily deformed. After proper stone care, the service life can be extended. Marble can maintain its original physical properties at room temperature.
Marble has beautiful colors and patterns, has high compressive strength and good physical and chemical properties, has a wide distribution of resources, and is easy to process. With the development of economy, the scope of application of marble has been continuously expanding, and the amount of marble has been increasing. Plays an important role. Especially in the past 10 years, the large-scale mining, industrial processing and international trade of marble have led to the large-scale entry of marble decorative plates into the architectural decoration industry, not only for luxurious public buildings but also for home decoration. Marble is mainly used for processing into various shapes and plates, and is used as a precious material for furniture inlays, such as walls, floors, tables and columns of buildings. It is also commonly used for monumental buildings such as monuments, towers, statues, etc. Marble can also be carved into works of art, stationery, lamps, utensils and other practical works of art. The texture of the marble is soft, artistic, elegant, and colorful. It is an ideal material for decoration of luxury buildings, and it is also a traditional material for art carving. Some marbles (including limestone, dolomite, marble, etc.) can also be made alkali-resistant. In the process of marble extraction and processing, gravel and corners are often used in the production of artificial stone, terrazzo, stone rice, and stone powder, and can be used for fillers in coatings, plastics, and rubber industries.
The natural marble color is beautiful and dignified. At present, no artificial material can replace the effect of natural marble. Its composition is different, causing its density, color, processing type and so on. So the use of a large range of different. Generally used for high-end places of the ground, walls, furniture decoration.
Editor's summary: Information on the main components of marble, the characteristics and uses of marble is presented here for everyone. I hope this article will be helpful to everyone.
