Most of the fluorescent sticks are strip-shaped and wrapped in polyethylene (plastic) with a glass tube in the middle. The liquids inside and outside the interlayer are peroxide and ester compounds respectively. After bending, beating and rubbing, the glass is broken, which causes the reaction of two compounds and makes the fluorescent dye glow. Glow sticks can be used for entertainment, night fishing, wedding, outdoor, military, engineering construction, underwater operation and so on.
The chemical substances in fluorescent sticks are mainly composed of three substances: peroxide, ester compounds and fluorescent dyes. Simply put, the principle of light-emitting rods is that peroxides react with ester compounds, and the energy after the reaction is transferred to fluorescent dyes, thus emitting fluorescence. 20 18 A glass tube interlayer is usually placed in the common fluorescent rods on the market, and the peroxide and ester compounds are isolated inside and outside the interlayer. After kneading, the two compounds react to make the fluorescent dye glow.
The glow stick consists of two parts: a plastic tube filled with different liquids and a glass tube. When in use, the fluorescent stick is bent slightly, the glass tube in the plastic pipe is broken, and the two liquids are shaken gently, so that the two liquids are fully mixed to achieve the best luminous effect.
