Preparation and properties study of double flame agent synergetic radiation yellow light illuminant

Abstract

Based on the principle of synergic radiation of double flame agent, a yellow light signal agent formula of red and green double flame agent is proposed, and the wavelength can be adjusted in the range of 576.4~591.3nm, the color changes from light yellow to dark yellow. Based on the theory of double flame agent synergetic radiation, the main illuminant components are Ba(NO3)2, SrNO3, Mg, shellac and PVC, to realize the yellow light color adjustable, and the best formula of yellow light color close to the traditional sodium salt illuminant was determined, and the flame combustion spectrum and luminous intensity of the illuminant were tested. The experimental results show that: By adjusting the ratio of two colors of flame, yellow illuminant with different wavelength and color purity can be obtained. When the ratio of Ba(NO3)2 to SrNO3 is 3:1, the color is more suitable for human observation, the formula is 40.5 % Ba(NO3)2, 13.5 % SrNO3, 40 % Mg, 2 % shellac and 4 % PVC, the luminous intensity is 222540.72cd, the wavelength is 587.5nm, and color purity is 74.1%.
