Granite is beautiful, durable and very hard. In ancient times, it would have been more popular than marble if mining and processing equipment and technology had been available.
Granite often contains other minerals, such as amphibole and mica, and a variety of colors, including: brown, green, red and common black and so on. Because it crystallizes very slowly, and its crystals are intertwined like a rubik’s cube. So we have a special cutting machine which is granite bridge saw machine.
So it’s hard. It is as durable as a house, does not drop debris, not easy to scratch, not afraid of high temperature. No matter color or light, want to have the common sense of a few conserve only, won’t fade or become dark. It is almost uncontaminated, and its polished surface is so shiny that impurities from all kinds of weather hardly stick.
Steel wire rope saw method is generally used to mine granite. New technologies such as dense row hole method and flame jet method appeared. Flame jet method of stone cutting seam neat, no damage, high production efficiency. The stone after the rough whole is called raw materials, then through artificial drilling or machine saw cut, the required size of the block, plate; Milling stone machine or rotary machine processing into cylindrical or curved body; Finally, manually cut coarse, fine rock grain, or machine grinding, polishing, so that the surface crystal bright. Granite does not pollute the environment. Synthetic materials are often accompanied by undesirable and even toxic by-products that need to be replaced several times over the life of the building (each time there is a disposal problem). Granite does not need replacing because it is very durable.
In addition, granite is very practical and can be made into a variety of surface – polishing, matt, fine grinding, fire, water knife treatment and sandblasting. Because granite often contains radioactive materials, it is necessary to measure the radiation level of granite before confirming its use.
Chinese granite mineral resources are also very rich, large reserves, varieties. According to investigation data statistic, the breed of design and color of Chinese natural granite is more than 100 kinds. Building decoration USES granite its decorative pattern, colour and lustre characteristic and raw material producing area name. Among them, the better ones are henan yanshi chrysanthemum green, snow green, yunlimei, jinan green in shandong, linzhou green in anyang, linzhou green, forest green, asbestos in sichuan, pea-green in jiangxi, zhongshan jade in guangdong, imperial consort red in lingqiu in shanxi, orange, hemp point white, green black flower, yellow black flower and so on. Granite from underground quality rock layer, after hundreds of millions of years of natural aging, form is very stable, do not have to worry about the conventional temperature difference and deformation. Granite platform by strict physical test and selection of granite, fine crystal, hard texture. Because granite is a non – metallic material, no magnetic reaction, no plastic deformation. Granite platform its hardness is high, so the accuracy of good retention. Because granite often contains radioactive materials, it is necessary to measure the radiation level of granite before confirming its use.
