Finally, I would like to remind you that the fluorescent stick contains toxic substances, so don't break the stick.
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. At present, a glass tube interlayer is usually placed in the common fluorescent rods on the market, and peroxides and esters are isolated inside and outside the interlayer. After kneading, the two compounds react to make the fluorescent dye glow.
At present, the luminous time of light sticks can range from 4 minutes to 48 hours.
The luminous time of the luminous rod is inversely proportional to the ambient temperature (that is, the higher the ambient temperature, the shorter the luminous time of the luminous rod) and the initial brightness of the luminous rod (that is, the higher the brightness when the luminous rod is just folded, the shorter the luminous time).
According to these characteristics of the glow stick, we can put the glow stick in a low temperature environment (such as refrigerator and freezer) to inhibit the chemical reaction of the two liquids in the glow stick, and then take it out and continue to use it.
