Far infrared ceramic powder is a white powder composed of a mixture of various substances. The main characteristic function of far-infrared ceramic powder is its ability to emit more far-infrared radiation (higher infrared emissivity) than normal objects. In high-temperature areas, it is mainly used for heating boilers, baking paint, heating and drying wood and food, etc; At room temperature, it is mainly used to manufacture various far-infrared insulation materials, such as far-infrared ceramic powder, far-infrared ceramic fiber, far-infrared ceramic polyester, and far-infrared functional ceramics. Far infrared ceramic coatings (including nano titanium oxide coatings) have catalytic oxidation function. Under sunlight (especially ultraviolet radiation), they generate negative monovalent hydroxide ions, which can effectively remove benzene, formaldehyde, sulfides, ammonia, and odor substances indoors, and have antibacterial function.
