Hoe werkt de UV -sticker?

UV stickers change the color of stickers by inducing chemical reactions under ultraviolet light. This type of sticker usually changes from dark purple to transparent when exposed to sunlight.

1. The principle of UV stickers

The main principle of UV stickers is to use the sensitivity of photosensitive materials to UV rays to change the color of stickers through chemical reactions. Photosensitive materials are photosensitive materials with special abilities that can sense light of specific wavelengths, including UV rays, visible light, infrared rays and other different wavelengths of light.

When UV rays are irradiated onto UV stickers, the photosensitive materials will undergo a chemical reaction. Through this chemical reaction, the photosensitive materials will release high-energy particles, which will react with the dye molecules in the stickers, causing the color of the stickers to change. Thus, we can use UV stickers to detect UV radiation.

2. The use of UV stickers

UV stickers are widely used in daily life and industrial production. In daily life, we can use UV stickers to detect UV radiation. For example, in outdoor camping, sports, tourism and other activities, UV stickers can be used to protect the skin and prevent skin damage caused by long-term exposure to UV rays.

In industrial production, UV stickers are also widely used. For example, in printing, dyeing, electronic manufacturing and other fields, UV stickers can be used to detect the level of UV radiation to ensure product quality and safety.

In short, UV stickers play an increasingly important role in modern society. Through UV stickers, we can better protect our health and ensure the safety and quality of industrial production.
