Unlike ordinary chemical components, fluorescent agents are not easily broken. If fluorescers accumulate in the human body, they can cause damage to the body’s immune system and weaken the body’s immunity.<\/p>\n

For example, if the fluorescein binds to the protein, it will prevent the wound from healing; the fluorescer can mutate the body’s cells; if the toxicity of the liver or other vital organs accumulates, it will become a potential carcinogen, causing damage to the blood system. The chemical substances can pollute the human blood, destroying the red blood cell membrane and causing hemolytic diseases.<\/p>\n

Fluorescent agents are now visible throughout our lives. In cosmetics, paper cups, and even some foods, there are fluorescing agents. why? Because many products require bright fluorescent whitening agents. But the truth is that if they get into our body the fluorescers are harmful to people. Since fluorescent whitening agents are known to be more and more people, UV flashlights have become popular UV detectors for measuring fluorescent agents.<\/p>\n

So, how do UV flashlights detect the presence of fluorescent agents in disposable cups? This is easy. The following test is performed with a normal UV flashlight<\/a>:<\/p>\n

Test object – paper cup:<\/p>\n

Turn the paper cup into a black box, turn on the UV flashlight, and illuminate the cup. If there is no color change in the World Cup, this indicates that the cup contains no fluorescent agent. If a fluorescent reaction occurs, there is a fluorescent agent in the cup.<\/p>\n

Test object – A4 paper:<\/p>\n

Paper cups that like to test, open the black box of white paper, turn on the UV lamp, if the paper turns bright blue, this means that the file contains many fluorescent agents.<\/p>\n

So, is the above test really correct?<\/p>\n

In fact, not all UV flashlights throw pure UV light. How to tell UV lamps<\/a> and other lights? This is easy. Ultraviolet light is invisible, so you can’t see it. But some of the light from the UV flashlight includes blue light that can be seen. This is why some people will find that even fluorescing papers emit light under ultraviolet light. Therefore, it is unreliable to test commonly used UV flashlight fluorescing agents, you need a professional UV flashlight.<\/p>\n

What kind of UV flashlight is the best fluorescent agent?<\/p>\n

According to the results of several experiments, it is preferred to detect the fluorescent agent between 254 nm ultraviolet light and 365 nm. If the paper cup, A4 paper, the mask contains a fluorescent whitening agent, the fluorescent agent reacts under ultraviolet light.<\/p>\n

Experimental results:<\/p>\n

Ultraviolet flashlight illumination, these fluorescent agents are items containing floodlights, indicating the ultraviolet light emitted by a flashlight, which can detect whether these items contain fluorescent agents.<\/p>\n

The fluorescein violet flashlights currently on the market are sold, and mothers should be careful when using them. “UV” has certain hazards to pregnant women, so it is recommended to reduce the use of this UV flashlight during pregnancy.<\/p>\n","protected":false},"excerpt":{"rendered":"
