Now, glow in the dark powder involves more and more fields, and the requirements for luminous powder are getting higher and higher. After buying the luminous powder, many customers use it in their products and find that luminous powder has lost its ability to emit light. Into white powder. In response to this problem, Glow Technology can answer your questions here.
Under normal circumstances, the luminous powder absorbs and emits light through the irradiation of light, which can be recycled and used unlimited times. However, in one case, the luminous powder will lose the luminous effect, that is, contact with the aqueous medium. After the ordinary luminous powder encounters water, it will be hydrolyzed, and the luminous powder after the release will lose the luminous effect and become a white powder.
In view of the fact that the luminous powder is not waterproof, the technicians continue to test and study. On the surface of the luminous powder, a film is coated to upgrade the non-waterproof luminous powder to a waterproof luminous powder. Luminous Technology has performed a waterproof test on waterproof luminous powder, comparing ordinary luminous powder and waterproof luminous powder in the same environment.
First, prepare two beakers, pour the same amount of water into the beaker, put ordinary luminous powder and waterproof luminous powder into the beaker at the same time, and stir. After the luminous powder is stirred, after soaking in water for one minute, the pH test paper of ordinary luminous powder becomes blue, and the pH test paper of waterproof luminous powder has no change.
After immersing the luminous powder in water for one hour, the pH test paper of the waterproof luminous powder did not change, the pH test paper of the ordinary luminous powder became dark blue, and the luminous powder began to hydrolyze. After storing the two kinds of luminous powder in water for one day, ordinary luminous powder has been hydrolyzed very seriously, and the luminous effect is getting weaker and weaker in the dark environment. After one day, the waterproof luminous powder has not changed, and the glow in the dark effect has not changed.
After testing, the waterproof luminous powder has a very good waterproof ability, and the ordinary luminous powder will hydrolyze immediately after contact with water and has no waterproof ability. Through the continuous testing of technical personnel, the performance of the waterproof luminous powder is summarized. The waterproof luminous powder can be immersed in water for more than one year without any change. It can be applied to any aqueous medium and humid environment.
