Understanding Pigment Powder

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.

3. Construction Materials Due to its fire-resistant properties, non-metallic mica powder is utilized in construction materials, including drywall, roofing shingles, and fireproof coatings. This usage not only enhances the safety of buildings but also improves the overall quality of construction products.

Unique Properties of Mica

The adaptability of modified plastics also lies in their ability to be engineered for specific functionalities. For example, certain modified plastics can be made to be fire-retardant, UV resistant, or even antimicrobial, broadening their applicability across various fields including medical devices, consumer products, and construction materials.

Mica is a very common rock-forming mineral, widely distributed in crystalline rocks. Its general chemical formula can be expressed as:

* Construction Mica is incorporated into roofing materials, paint, and joint fillers to enhance durability and thermal resistance.

Safety and Regulatory Aspects

Mica powder, known as industrial monosodium glutamate, is widely used. With the continuous development of technology and application market, and some new requirements have been put forward for the quality of mica powder, so synthetic mica powder has been developed. Compared with the natural mica powder processed by natural mica ore, and the synthetic mica powder synthesized by using a variety of raw materials through high temperature reaction and other chemical methods. What are the advantages and differences between them?
