granite

Product Name: Granite Product Origin: Wenzhou Product Features: Excellent texture, acid resistance, corrosion resistance and wear resistance Product Description: Granite is a widely used building material. Ouhai granite resources are rich, widely distributed and varied, including white, green, black, blue, purplish red, blue and white, sesame flowers and so on. Folk tradition uses granite to build houses, roads and bridges. According to the survey, Daluo Mountain in the southeast of Ouhai covers an area of about 109 square kilometers and contains more than 10 billion cubic meters of granite. After technical appraisal, it contains a high amount of Shi Ying and little iron, and its crystal combination is very tight, with excellent texture, acid resistance, corrosion resistance and wear resistance. It is a high-quality corrosion-resistant material and can be used in chemical industry, metallurgy, brewing, printing and dyeing, national defense facilities and so on. Product history: Granite belongs to igneous rock, which is formed by underground magma ejection and intrusion cooling crystallization, as well as granitic metamorphic rocks. With visible crystal structure and texture. It consists of feldspar (usually potash feldspar and anorthite) and Shi Ying, mixed with a small amount of mica (biotite or muscovite) and trace minerals, such as zircon, apatite, magnetite, ilmenite and sphene. The main component of granite is silicon dioxide, and its content is about 65%-85%. The chemical properties of granite are weakly acidic. Usually, granite is slightly white or gray. Because it is mixed with dark crystals, its appearance is spotted. The addition of potash feldspar makes it red or flesh-colored. Granite is formed by the slow cooling and crystallization of magma, which is deeply buried under the ground. When the cooling rate is extremely slow, it forms a kind of granite with very rough texture, which is called crystalline granite. Granite and other crystalline rocks constitute the foundation of continental plate, and it is also the most common intrusive rock exposed on the earth's surface. Although granites are considered as igneous rocks formed by melted materials or magma, there is a lot of evidence that some granites are formed by local deformation or the products of previous rocks, which have been rearranged and recrystallized without liquid or melting process.
