What is mica, and what are the applications of mica?
Industrial production requires a large amount of raw materials, some raw materials are directly extracted from the natural world, and some raw materials need to be manually processed. Many people know a lot about industrial products, but they know very little about the raw materials they produce. In fact, many industrial products use some natural raw materials. Mineral resources are one of the indispensable natural resources in many industrial productions. For example, the iron and steel industry is based on iron ore resources, while the non-ferrous metal smelting industry is based on non-ferrous metal ore. There are many kinds of mineral resources in nature. They are important industrial raw materials, but we may not know about many mineral resources. For example, do you know what mica mines are? What types of mica are there? What are the applications of mica in industrial production?
First, what is mica?
It is well known that the earth's crust is composed of rocks, and the rock is composed of a single mineral or many types of minerals. Mica is one of the common rock-forming minerals. Mica has a hexagonal plate-like crystal shape, which is a general term for mica minerals. They are chemically composed of aluminosilicates of magnesium, iron, potassium, aluminum, and the like. The mica minerals mainly include muscovite, biotite and lithium mica. These three types of mica minerals also contain many subtypes. For example, muscovite includes sericite, sodium mica, etc., while biotite includes gold. Mica, iron biotite, manganese biotite, etc.
Second, the application of mica mine
Mica has the greatest advantages of minerals such as insulation, high temperature resistance and salt and alkali corrosion resistance. Therefore, it is widely used in many fields of industrial production. Different types of mica mines have different specific characteristics, so their specific uses are also different, but in summary, there are mainly the following types of applications:
1. As a raw material for various machine parts and components
Since the biotite has good insulation, high temperature resistance, salt and alkali resistance, they are often used to make various electrical equipment and electricians. Insulation material for the equipment. In addition, it can also be used to make parts for smelting furnaces and machinery on steam furnaces.
2. As an additive to various industrial materials
Many building materials need to be added with special ingredients to improve the properties of the materials. Muscovite and phlogopite are the most commonly used additives in the production of many building materials. For example, the production of industrial asphalt, paints, paints, fire extinguishing agents, etc., often adds muscovite to improve the properties of the material.
3, other applications of mica can be directly used to manufacture various types of insulation materials, mica and mica powder can also be used to make mica paper.
In addition, mica also has a certain medicinal value, which can be used to treat diseases such as muscle necrosis and general weakness. As a kind of mineral resource, mica has been gradually recognized by people in recent years and is well known. The distribution of such mineral resources in China is also very uneven. At present, the mica deposits found in China are very uneven. It is mainly distributed in the three provinces of Xinjiang, Sichuan and Inner Mongolia. The reserves of mica deposits in Xinjiang account for the vast majority of the country.
