The rapid development of new energy vehicles, batteries and other emerging industries also provides a new application scenario for mica products, such as power battery modules and energy storage system of mica cover plate, mica partition, mica monitoring board and composite mica tape and other products, the application of mica provides the industry with a fire safety solution.
Mixing and Blending: The mica powder and resin are mixed in a controlled environment to ensure uniform distribution. This step is crucial for achieving the desired properties in the final product.
Natural high quality Muscovite:feel fine, soft lubrication.
X represents large interlayer cations, such as K+, Na+, Ca2+, Ba2+, Rb+, Cs+, etc. Y represents octahedral cations, such as Al3+, Fe2+, Mg2+, Cr3+, Ti4+, Fe3+, etc. Z is mainly Si4+ and Al3+; The ideal ratio of the additional anion (OH)- to (O)2- is 2:10, and (OH)- can be replaced by F- and Cl-. Most mica contain 4% to 5% water. Therefore, although they may be called mica, the chemical composition of different mica may be very different, for the purpose of research, we collectively refer to the minerals with this type of characteristics as mica group minerals.
Natural mica powder and synthetic mica powder also have great differences in electrical insulation, mechanical properties, chemical stability, application range and cost. Natural mica powder has good electrical insulation, but the volume resistivity is lower than that of synthetic mica. Synthetic mica powder has better electrical insulation properties, high volume resistivity and stable dielectric constant, and is suitable for high performance electrical insulation materials. The hardness of natural mica powder is relatively low (2-3), and it has good elasticity and peeling property. The hardness of synthetic mica powder is higher (between 3 and 4), and the tensile strength and compressive strength are better than that of natural mica powder. Natural mica powder is stable in acid-base solution, but it is easy to decompose at high temperature. Synthetic mica powder is stable to acid and base at room temperature, but will be slowly corroded by sulfuric acid above 300℃. Better thermal stability, not easy to release gas. Natural mica powder is widely used in electrical appliances, welding rods, rubber, plastics, paper making, paint and other fields. Synthetic mica powder is mainly used in high-end electrical insulation materials, aviation, aerospace, national defense industry and other high-tech fields. Because synthetic mica powder needs to be produced through complex chemical processes, its production cost is usually higher than that of natural mica powder. Therefore, in the market, the price of synthetic mica powder is often higher than that of natural mica powder. However, with the continuous progress of production technology and the gradual emergence of scale effects, the price of synthetic mica powder is expected to gradually decrease.
In 2022, Lingshou Huajing Mica Co., Ltd. launched cosmetic grade mica powder. The flake structure of mica powder can lock the water on the surface of the skin, forming a protective film to effectively prevent water loss. Its unique gloss and reflection effect add natural and charming luster to the skin, and mica powder also has a certain sunscreen effect. To a certain extent, it can reduce the damage of ultraviolet rays on the skin, protect the skin from the external environment, and prevent sunburn.
The mica variety that does not contain iron is colorless in flakes, and the higher the iron content, the darker the color, and the more polychromatic and absorbable it is. According to the different chemical composition and optical characteristics, mica group minerals can be divided into Muscovite subgroup, biotite-phlogopite subgroup and lemica subgroup. The common mica are biotite, phlogopite, Muscovite and so on.
The rapid development of new energy vehicles, batteries and other emerging industries also provides a new application scenario for mica products, such as power battery modules and energy storage system of mica cover plate, mica partition, mica monitoring board and composite mica tape and other products, the application of mica provides the industry with a fire safety solution.
For example, the safe operation of high-speed rail cannot be separated from the escort of mica products.
It is an indispensable and important raw material in the fields of electric heating equipment, wire and cable, aerospace and so on.
The common characteristics of mica group minerals are: layered silicate minerals, monoclinic crystal system, a few trigonal crystal system, the crystals are pseudo-hexagonal columnar, plate and sheet; The aggregate is scaly and foliaceous. It has a set of extremely complete cleavage, along which it is easy to peel into sheets. Therefore, the shape of mica is usually regarded as sheet.
Mica has a wide range of uses, in ancient China, it is often used to do traditional Chinese medicine, the ancients even think that taking mica: a year to remove all diseases (heavy metal poisoning), three years of long service, husband into a boy (body scrap), Zhongshan uncle Qing suit, over time can become a cloud (soul ascension). However, in the era without glass, the transparency of mica makes it a better decorative material, for example, we are familiar with the mica screen candle shadow deep, the river gradually falling Xiaoxing sink. Mica screen is low, tassel tent is small and mica calf car.
