UVB Also known as medium-wave ultraviolet or far ultraviolet. Its main function is to have erythema effect on the human body. It can promote mineral metabolism and the formation of vitamin D in the body. Utilizing the erythema reaction, UVB is widely used in medical treatment, such as the treatment of skin diseases. But the irradiation methods and applicable symptoms of ultraviolet therapy are generally used in hospitals , and consumers cannot use them by themselves. UVC It is also called short-wave ultraviolet or deep ultraviolet. Because of its shortest wavelength and the largest photon energy, it can most trigger [...]

Appreciation of jadeite Under the illumination of a jade flashlight, crystal-like substances such as monosodium glutamate and salt may appear in jadeite. If you can’t see such a substance under the light, there may be two situations: this item is not real jade, it may be glass; It may be a sky-high jadeite. The color of good jade is generally evenly distributed, and the internal lines of the jade cannot be seen, but after dyeing, there is a color difference between the crystal grain jade and the gap, and it appears as a spider web under the light of a [...]

? Ultraviolet light is an electromagnetic wave with a wavelength between 10nm and 400nm. It belongs to the invisible light other than the seven-color light (Red orange yellow green cyan blue purple) visible to the human eye. From the wave-particle duality of light, ultraviolet light is shorter than visible light because of its wavelength, Its penetration in the propagation process is very weak, but it causes photon energy to be greater than visible light, and it is easier to trigger a series of photochemical reactions and electronic transitions after irradiating substances. The application of ultraviolet rays is based on the [...]

Excite fluorescent substances to produce fluorescent reactions When ultraviolet rays hit certain substances, these substances emit visible light of various colors and different intensities, and when the light source stops irradiating, this light disappears. These substances that emit fluorescence are fluorescent substances. Fluorescent substances are widely present around our lives, such as fluorescent agents (whitening agents), fluorescent minerals, petroleum, biological oils and other fatty compounds, as well as some organic macromolecular compounds (vitamins, amino acids), etc., so we can use the fluorescent reaction in some applications.

Although the light source in the ultraviolet band cannot participate in the photosynthesis of plants. But it can cause plants to have special morphology, with short stems, shrunk leaf surfaces, developed furry, increased accumulation, increased chlorophyll, and anthocyanins in the stems and leaves, and the colors are particularly gorgeous. In addition, ultraviolet rays are harmful to plant microorganisms. Use lamps that can provide low-dose ultraviolet rays to kill pathogens without harming plants. For example, certain bacteria can cause plant diseases such as wilt and rust, and the technology has also been proven effective against downy mildew and some pests. Insect [...]

UV curing objects can be divided into three types: Coatings, inks and adhesives. The coatings are mainly used as protective layers, such as wood coatings for home building materials, plastic and metal coatings used in home appliances and automobiles, and optical fiber and cable coating materials. The ink is mainly used in the printing field. Viscose is the most widely used in the field, such as the adhesion of glass and handicrafts, jewelry positioning, nail polish curing in the beauty industry, and medical device bonding. No matter UV coating, ink or glue, it has a natural advantage, that is, there [...]
