Granite is beautiful, durable and very hard. In ancient times, if there were perfect mining and processing equipment and technology, it would definitely be more popular than marble.
Granite often contains other minerals, such as amphibole and mica, and comes in a variety of colors, including brown, green, red, and common black. Because its crystallization process is very slow, its crystals are intertwined one by one like a Rubik's cube,
So it's very hard. It is as durable as a house, does not drop debris, is not easily scratched, and is not afraid of high temperatures. Regardless of color or light, as long as there is some maintenance common sense, it will not fade or darken. He is almost free from contamination, the surface gloss after polishing is very high, and the impurities brought by various weather can hardly adhere.
Wire rope sawing is generally used for mining granite. New processes such as dense row eye method and flame spray method have appeared. The stones mined by the flame jet method are neatly cut without dark injuries and high production efficiency. The mined stones are called rough blocks after roughing, and then drilled with artificial drill holes or machine sewing to obtain blocks and plates of the required size; processed with a stone milling machine or a rotary bed to become cylindrical Or curved body; at the end, cut coarse and fine rock-like patterns manually, or grind and polish with a machine to make the surface shiny and bright. Granite does not pollute the environment. Synthetic materials are often accompanied by bad or even toxic by-products and need to be replaced several times during the life of the building (each time there will be handling issues). Granite does not need to be replaced because it is very durable.
In addition, granite is very practical and can be made into a variety of surfaces-polished, matte, finely ground, fired, waterjet treated, and sandblasted. Because granite often contains radioactive materials, when using granite, it is necessary to measure its radiation level, and then confirm its use.
