Gold drill granite manufacturer

Gold drill granite manufacturer Granite is a igneous rocks, granite belonging to igneous rock is volcanic eruption magma or lava rocks crystallized condensate. The main component is silicon dioxide, about 65% -75%, are acidic rock. When the crystal, granular structure, visible particles spotted on a solid appearance. Granite Rock hard dense, abrasion resistance, corrosion resistance, so often used as a building exterior decorative use. Which contains a proportion of the amount of radiation the size of its specific composition formed varies, some radiation levels exceeded the standard, it is not recommended for large-scale use indoors (especially colors more vivid shades of red, etc.), but do indoor windowsill, stove, stone gate decorated office use. Qingdao Peng Jun stone factory is set mining, wholesale blocks, stone processing and sales in one of the large companies. Company size, strong technical force, all kinds of processing and mining equipment, products sold throughout the country and exported to many countries. The company has advanced management mechanism, first-class production technology, rich experience in processing, improve the sales system, the development of enterprises laid a solid foundation. The main production cherry safflower, sesame white, gold linen, Pingdu gray, crystal white, sesame gray, shaped stone, Laizhou green, gold drilling, garnet red, white linen, Huang Jin Bala, pearl flowers, pearls red granite products. 1) ,, applicable public places and outdoor decoration. 2), with excellent processing performance: sawing, cutting, grinding, drilling and carving. Its processing accuracy of 0.5μm or less, and luminosity of 1,600 or more. 3), wear resistance, and 5-10 times higher than cast iron. 4), the thermal expansion coefficient is small, not easily deformed, and indium steel similar, affected by temperature minimal. 5), elastic modulus, higher than cast iron. 6), rigid, internal damping, large 15 times greater than steel. You can shock, shock absorption. 7), granite brittle, damaged after only a partial loss, does not affect the overall flatness. 8), chemically stable granite, difficult to weathering, to acid, alkali erosion and corrosive gases, proportional to their chemical nature and silica content, the service life of up to 200 years. 9), the granite is not conductive, non-magnetic field is stable. Generally, granite is divided into three different categories: fine-grained granite: feldspar crystals average diameter of 1/16 to 1/8 inches. Medium-grained granite: feldspar crystals average diameter of about 1/4 inch. Coarse-grained granite: feldspar crystals average diameter of about 1/2 inch and larger diameter of crystal, some even up to a few centimeters, coarse-grained granite relatively low density.
