Wavelength classification and application fields of ultraviolet light According to the different biological effects, ultraviolet rays are divided into four wavelength bands according to wavelength: long-wave UVA, medium-wave UVB, short-wave UVC, and vacuum UVD. The longer the wavelength, the greater the penetration.   UVA Long wave UVA, with a wavelength ranging from 320 to 400 nanometers, is also known as long wave black spot effect ultraviolet radiation. Has strong penetrating power, able to penetrate glass, even up to 9 feet of water; And it exists throughout the year, regardless of whether it is cloudy or sunny, day or night.   Harm to human body: More than 95% of the ultraviolet rays that daily skin comes into contact with are UVA, so it causes the greatest damage to the skin. UVA can attack the dermis through the epidermis, causing severe damage to collagen and elastin in the skin; Moreover, dermal cells have poor self-protection ability, and a small amount of UVA can cause great harm. Over time, the skin develops problems such as looseness, wrinkles, and the appearance of microvessels.   At the same time, it can also activate tyrosinase, leading to immediate melanin deposition and the formation of new melanin, making the skin black and lacking luster. UVA can cause long-term, chronic, and long-lasting damage, leading to premature aging of the skin, hence it is also known as aging radiation.   Application field: UVA ultraviolet radiation with a wavelength of 360nm conforms to the phototactic response curve of insects and can be used to make insect traps. UVA ultraviolet rays with wavelengths of 300-420nm can pass through specially colored glass tubes that completely cut off visible light, emitting only near-ultraviolet light centered at 365nm. They can be used for ore identification, stage decoration, currency verification, and other places.

Welcome to our company to negotiate business and looking forward to mutual growth and devlopment！   Ultraviolet (UV LED) curing principle: UV light curing system is divided into free radical system and cationic system, and the curing mechanism of different systems is different. Free radicals are mainly generated by light irradiation, which initiates polymerization and crosslinking reaction of monomers and prepolymers to achieve the effect of curing. The cationic system is a process in which the cationic photoinitiator is irradiated to generate a strong protic acid, and addition polymerization occurs to make the resin achieve a curing process.   Characteristics and uses of UV LED products: Widely used in banknote checking , UV detection , manicure , medical treatment , printing , adhesive curing , ink curing , Paint curing , etc . Large area curing , inkjet printing, curing outer coatings of wires and optical fibers , Material Irradiation Catalysis , Biological Experiments and Touch Screen Curing.   Advantages of UV LED Light Source : 1. Uniform , stable , strong illumination , shorten the curing time of products , improve production eficiency . 2. Low thermal radiation , especially suitable for liquid crystal display edge sealing , plastic substrate curing . Thin material printing , medical devices require a small heating area occasionally . 3. Low energy consumption ,10% power consumption of traditional mercury lamp curing machine , can save 90% of the electricity . 4. Reliable , the life of LED can reach more than 20000 hours , reducing the cost of consumption . 5.According to the actual application of customers , the shape and size of the luminous region of the UVLED can be customized according to the needs. 6. Ultraviolet LED light source does not need preheating and does not contain toxic mercury . Secondly , the power dissipation of the UVLED is much lower compared to traditional high - pressure mercury lamps. It takes hundreds even thousands of watts more for mercury lamps to produce the same effects and it needs to be preheated for about ten minutes . The lamp tube of mercury lamps also contains toxic substance "mercury". UV LEDs are safer and more environmental friendly choice over traditional technologies.

What is UV LED light curing system? What are the characteristics of UV light curing? In recent years, UV LED light curing technology has received close attention from the world, and many industrial production fields are gradually choosing UV LED light sources to replace traditional UV mercury lights. The UV LED light curing technology is environmental friendly that realizes the concept of environmental sustainability through use of light emitting diodes. Compared with the traditional UV mercury lamps, it has more higher efficiency and low energy consumption. Following are a few features of UV LED light curing:   1. The characteristics of the UV LED light source are that it belongs to a single-band ultraviolet light, with high luminous efficiency and low energy consumption. The UV LED light source can convert electrical energy into light energy through the led chip, and can emit a single-band ultraviolet light source. 365/385/395/405nm these bands. Compared with the traditional UV mercury lamp, only a small part of the full-band ultraviolet light emitted can actually exert energy efficiency. At the same time, the mercury lamp will generate a large amount of heat energy when it is in use, resulting in a large amount of energy consumption to a large extent;   2. UV LED light curing belongs to a kind of "cold light source", which does not generate infrared band and emits a lot of thermal energy, thereby causing thermal damage to the surface of the substrate. Like some ink printing fields, chip processing, liquid crystal display packaging and other fields, UV LED light sources are basically used for product processing;   3. The UV LED light curing system adopts a unique control panel, which can be used immediately when the power is turned on. It does not need to be preheated in advance like the traditional mercury lamp curing, and there is no need to worry about the regular replacement of consumables due to the life of the lamp like the mercury lamp. . UV LED light curing can instantly light up the lamp beads, and the power (10-100%) can be adjusted at will, which not only saves energy, but also is easy to operate!   4. The maintenance cost of UV LED light source is low. Usually, the use time of a UV LED curing machine is about 25000h, which is 5-8 times that of traditional UV mercury lamp. Due to the life of the lamp beads, almost no maintenance is required, which effectively reduces the cost of equipment maintenance;   5. The UV LED light curing system is mainly divided into UV LED spotlights, UV LED line light source, UV LED surface light source, UV LED curing lamps, UV LED water cooled machine, etc. according to its use environment, and the luminous size and irradiation can be customized according to the actual working conditions Area, the irradiation position is matched with the equipment, no large-scale machinery and pipeline installation are required, it can be adapted to work in a variety of environments, and the work efficiency of the assembly line is improved.   6. As a manufacturer of UV LED curing machines, Yuanming Technology provides a complete set of curing solutions for UV curing problems in various industries. We can provide a variety of conventional models to choose from, and can also customize according to the actual use of customers. Use standard products.
