Marble Grinding Powder Performance Characteristics

Marble, also known as marble, is a recrystallized limestone, the main component is CaCO3. The limestone softens under high temperature and pressure and recrystallizes to form marble when the minerals contained change. The main ingredients are calcium and dolomite, which are many colors, usually have obvious patterns, and have many mineral particles. The Mohs hardness is between 2.5 and 5. Because marble generally contains impurities, and calcium carbonate in the atmosphere by carbon dioxide, carbides, water vapor, but also easy to weather and dissolve, and the surface quickly loses luster. 

Performance Characteristics

Marble is generally physically softer, which is relative to granite. In interior decoration, TV countertops, window sills, indoor floors, etc. are suitable for the use of marble. Marble is a trade name, not a petrology definition. Marble is a type of natural architectural decorative stone, generally refers to the decorative function, can be processed into building stone or handicrafts of the deteriorated or unnatured carbonate rock. 

Non-deformation: The rock has a long-term natural aging, uniform tissue structure, small linear expansion coefficient, and disappears internal stress without deformation. 

High hardness: good rigidity, high hardness, strong wear resistance, small temperature deformation. 

Long service life: no need to apply oil, not easy to stick to dust, maintenance, maintenance is convenient and simple, long service life. No scratches, no constant temperature conditions, and its original physical properties are maintained at room temperature. 

Non-magnetization: can move smoothly when measuring, no sense of stagnation, not affected by moisture, and the plane is weighed well. 

Physical Properties

• specific gravity:2970-3070kg/m3 
• compressive strength: 2500-2600kg/cm3 
• elastic coefficient: 1.3-1.5×106kg/cm2

Apply The Orientation

It is mainly used for processing into various shapes and plates, as the walls, floors, platforms, columns of buildings, and is also often used as materials for monumental buildings such as monuments, towers, statues, etc. Marble can also be carved into arts and crafts, stationery, lamps, utensils and other practical works of art. Soft in texture, it is a decorative material and a traditional material for artistic carving. 

The main color of this stone is: multi-color, subjective properties are: pattern, has high compressive strength and good physical and chemical properties, easy to process, with the development of the economy, the scope of application continues to expand, the amount of use is getting larger and larger, playing an important role in people's lives.

In particular, large-scale mining and industrial processing have made decorative panels enter the building decoration industry in large quantities, not only for public buildings, but also for home decoration. It is also widely used in the manufacture of utensils, such as furniture, lamps, smoking equipment and art carving. Some can also be used as alkali-resistant materials. The crushed stone and corner residue produced in the mining and processing process are also commonly used in the production of artificial stone, terrazzo, stone rice and stone powder, and can be used for fillers in coatings, plastics, rubber and other industries.
