Far-infrared powder is a white powder composed of various substances. Its primary feature is its ability to emit more far-infrared radiation (higher infrared emissivity) than normal objects. It is mainly used in high-temperature areas for boiler heating, paint baking, and the heating and drying of wood and food. In normal temperature areas, it is primarily used in the production of various far-infrared thermal insulation materials, such as far-infrared ceramic powder, far-infrared ceramic fiber, far-infrared ceramic polyester, and functional ceramic materials. Far-infrared ceramic coatings (including nano-titanium oxide coatings) have a catalytic oxidation function. Under sunlight (especially UV rays), they generate hydroxide ions with a negative charge, effectively removing odorous substances indoors and possessing bactericidal properties.
