Mica powder is a natural mineral pigment derived from mica, a group of silicate minerals. Mica itself is known for its excellent heat and electrical insulation properties, but when ground into a fine powder, it transforms into a brilliant colorant. Mica powder is available in various colors and finishes, including matte, metallic, and pearlescent. This diversity allows artists to experiment with different shades and effects, making it a popular choice for resin coloring.
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.
These components require materials with high strength, toughness, impact resistance, and other properties, and modified plastics precisely meet these requirements.
La pintura aislante es un producto de recubrimiento que está formulado con partículas que poseen propiedades de aislamiento. Estas partículas pueden ser de diversos materiales, como microesferas de vidrio, polímeros o incluso componentes cerámicos. La principal función de esta pintura es mejorar la eficiencia energética del hogar al reducir la transferencia de calor a través de las paredes. Esto significa que en invierno, el calor generado por sistemas de calefacción se mantiene en el interior, mientras que en verano, el calor exterior se reduce, manteniendo un ambiente más fresco.
One of the defining characteristics of pearl pigments is their ability to reflect and refract light. This unique optical effect results in a shimmer that can range from subtle to dramatic, depending on the formulation and application. Pearl pigments can be produced in a myriad of colors, each with its distinct undertones, allowing for endless creativity. Furthermore, they are durable and resistant to fading, ensuring that the beauty they impart stands the test of time.
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.
Moreover, the aesthetic appeal of decorative mica sheets cannot be understated. Their natural shimmer and coloration can add depth and sophistication to any design. When light interacts with mica, it creates a stunning visual effect that can elevate the overall ambiance of a space. Whether used as a feature wall, in cabinetry, or for decorative accents, mica sheets can transform ordinary spaces into extraordinary ones.
Take pearlescent pigments as an example, pearlescent pigments are a class of pigments with pearl luster, which are deposited on the substrate (generally natural mica, synthetic mica, glass sheet and other sheet-like materials) above a layer or alternately deposited multiple layers of metal oxides or non-metallic oxides and formed a flat sandwich body with a structure similar to sandwich. Due to the difference in refractive index between the substrate and the oxide deposited on its surface and each oxide, when the light shines on the surface of the pearlescent pigment, the incident light will be refracted and reflected at the interface of each layer of the pearlescent pigment, and the color of the pearlescent pigment that people see is the result of the superposition of light after multiple refractions and reflections of the light, that is, the interference phenomenon of light.
Conclusion
Non-metallic mica powder is derived from mica minerals, primarily muscovite and phlogopite. These minerals are ground into fine powder, which retains the natural glitter and luster of mica. The powder is characterized by its high silicate content, layered structure, and excellent thermal and electrical insulating properties. Unlike metallic minerals, non-metallic mica powder does not contain heavy metals, making it environmentally friendly and safe for use in various applications.
