Granite is beautiful, durable, very hard. In ancient times, if there were sophisticated mining, processing equipment and technology, it was definitely more popular than marble.
Granite often contains other minerals, such as hornblende and Mica, and presents a variety of colors, including: Brown, green, red, and common black. Because the crystallization process is slow, its crystals are interwoven together as a cube,
So it's hard. It is as durable as the house, not to drop debris, not easy to scratch, not afraid of high temperatures. Regardless of color or brightness, as long as there are some curing common sense, will not fade or darken. He is hardly contaminated, polished after a high surface gloss, all kinds of weather caused by impurities can hardly glue.
Steel Wire Rope saws for mining granite are generally used. A new process of dense eye-drainage and flame spraying is presented. Flame Spray method Mining stones cut neatly, not internal, high production efficiency. Mined stones are coarse after the whole, known as the shortage of material, and then by artificial drill wedge or machine saw cut, to make the required size of the block, plate; use milling stone machine or rotary bed processing, become cylindrical or arc body; finally artificially chopped coarse, fine rock lines, or machine grinding, polishing, so that the surface crystal bright. Granite does not pollute the environment. Synthetic materials are often accompanied by bad or even toxic by-products, which need to be replaced several times during the construction period (each time will be dealt with problems). Granite does not need to be replaced because it is very durable.
In addition, granite is very practical, can be made into a variety of surfaces-polishing, matte, fine grinding, fire, water knife treatment and sandblasting. Since the granite often contains radioactive substances, the use of granite is required to measure its radiation level, and then confirm its use.
