Theoretical Calculation for Far Infrared Emissivity of Tourmaline Powder Materials
The chemical composition of tourmaline crystal structure was investigated by using Diamond software and the relationship between the far infrared emissivity and the parameters of composition, structure and particle size of tourmaline materials was analyzed, and then four effective factors on the infrared emissivity were determined. By analyzing the effect of the variables on the emissivity, an effective function of the single variable on the emissivity was set up. Considering the weight coefficient of each factor, a calculation model on the far infrared emissivity of tourmaline was built up. Using this theoretical model, the method to improve the far infrared emission was discussed.
