Granite is a volcanic eruption of lava and is subjected to considerable pressure to bulge in the molten state to the tectonic rocks of the surface of the earth's crust. In the formation of the surface layer of the earth's crust, it slowly moves to cool down. It is a kind of igneous rock, which is a substance formed by cooling and solidifying crystals of magma or lava containing silicate (silicate) melt. When the molten magma freezes and solidifies, the mineral is formed in igneous rocks, such as olivine and pyroxene. The most dense iron- magnesium silicate mineral is formed at the highest magma temperature; minerals with lower density, such as feldspar and quartz , form in the later stages of cooling. Minerals formed in lava can usually grow without any restraint and have well-developed crystal forms.

Because granite is second only to diamonds and durable, it is clearly the ideal material for wall tiles and floor tiles. Because granite is rarer than ceramics or any other man-made material, laying granite floors can greatly increase the value of a large property. Granite is available in a wide range of colours and offers a wide range of options. Granite countertops are easy to maintain and have a strong anti-fouling capability. In general, granite floor tiles provide users with an extremely durable and easy to maintain surface. In addition, unlike synthetic synthetic materials, natural granite countertops have unique temperature resistance, making them the first choice for all types of sheet metal processing.

A deep-form acid igneous rock belonging to magmatic rock. Commonly known as granite. The silica content is more than 70%. The block has no bedding, and the granite inlaid structure is often weathered by globular. The color is lighter, and it is more common in grayish white and flesh red. It is mainly composed of dark minerals such as quartz (hardness 7), feldspar (hardness 6) and a small amount of biotite (hardness 2 to 4). The quartz content is 20% to 40%, and the alkaline feldspar is more than the plagioclase, accounting for more than 2/3 of the total feldspar. Alkaline feldspar is a variety of potassium feldspar and albite, and plagioclase is mainly sodium longer or longer. Dark minerals are mainly composed of biotite and contain a small amount of amphibole. It has a granitic structure or a plaque-like structure.
In terms of genesis, some people think that granite is a granitoid slurry deep in the earth's crust, which is formed by condensation crystallization or crystallization from basalt magma. It is also considered to be the result of granitization caused by deep metamorphism and metasomatism. Many non-ferrous metal minerals such as copper, lead, zinc, tungsten, tin, bismuth, molybdenum, precious metals such as gold, silver and other precious metals such as niobium, tantalum, beryllium, radioactive elements such as uranium, thorium, etc., are related to granite . The granite structure is uniform, the texture is hard, and the color is beautiful. It is a high-quality building stone.
Flat disk Rotary Damper mainly used for large diameter, small height space. Disk dampers provide energy absorption and rotational deceleration. We offer many different models from mild to extreme.
