For example, the safe operation of high-speed rail cannot be separated from the escort of mica products.

In the realm of modern construction and home improvement, external wall insulation has become a crucial topic, especially given the rising concerns related to energy efficiency and environmental sustainability. Among the various methods to improve the thermal performance of buildings, the use of external wall insulation paint is garnering significant attention. This article delves into the benefits, applications, and considerations related to external wall insulation paint.

Once the raw mica reaches the factory floor, it undergoes several stages of refinement, each executed with surgical precision. The slicing of mica sheets is a critical process that demands both state-of-the-art machinery and the keen oversight of trained technicians. These technicians are not just operators but custodians of quality, ensuring that each sheet meets stringent industrial standards. Their competence establishes the factory’s reputation for excellence, as consistency in product quality is non-negotiable in competitive markets.

Characteristics of Mica-Based Pearl Pigments

Environmental Considerations: Synthetic mica has a smaller environmental footprint since it doesn't involve mining operations that can harm ecosystems. The controlled production process also generates less waste compared to the extraction and refinement of natural mica.

Once extracted, mica undergoes several processing stages to refine and enhance its properties. The raw mica is first crushed and ground into fine particles, an essential step for its integration into various products. Depending on the intended use, it can be purified to remove impurities, enhancing its value. For instance, in the cosmetics industry, high-purity mica is preferred for its shimmering and reflective qualities used in eyeshadows, blushes, and other beauty products.

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.

Natural mica powder and synthetic mica powder have differences in production methods, heat resistance and color transparency. As the name suggests, natural mica powder is made from natural mica ore after processing, retaining the original characteristics and composition of the ore. Its main components are SiO2 (about 49%) and Al2O3 (about 30%), while also containing K2O+Na2O (9%-11%) and so on. The synthetic mica powder (such as fluoroglogopicite powder), is the use of a variety of raw materials through high temperature reaction and other chemical methods synthetic, its composition and characteristics can be adjusted and optimized according to the need, the chemical formula is KMg3(AlSi3O10)F2, belongs to the monoclinic crystal system, is a typical layered silicate, relatively single and pure composition. The heat resistance of natural mica powder is generally 500-600℃, and some types, such as phlogopite, can reach 800℃. The heat resistance of synthetic mica powder is more excellent, and it can withstand high temperatures above 1200℃, and the melting point or crystallization temperature is about 1375±5. The transparency of natural mica powder is relatively low, and the color is diverse, including black, yellow, white, gray, green, brown and other colors, and may vary due to different ore types and processing methods. The color of synthetic mica powder is relatively single, usually colorless transparent or white, high whiteness, good optical performance, and high transmittance from ultraviolet to infrared band.
