What Is UV Curing?

A sterilization method for killing various microorganisms. It has many sterilization advantages and a wide range of applications.

UV curing

(1) Sterilization principle:

The ultraviolet sterilization by LED is to destroy and change the microorganisms by ultraviolet radiation.

1) The elderly are susceptible to germs due to the gradual aging of their bodies, and they will also infect other people at home; infants and young children are most likely to suffer from skin diseases, respiratory infections, various cold symptoms, diarrhea and other pain, mostly due to bacteria And virus damage; some patients in the family carry some bacteria themselves, coupled with weak health, poor resistance, it is easy for family members or themselves to be infected by germs. You can use the Risente tabletop UV germicidal lamp once a day for all-round sterilization and disinfection of ultraviolet rays.

2) Basement, semi-basement, not ventilated, rarely touch the sun. These places are particularly susceptible to breeding bacteria. You need to pay attention to sterilization and disinfection. Family members also need to sunbathe. You can use the sunbathing lamp in the Risente sterilization lamp box to bring sunlight into the room.

3) Pets or small animals are the fastest spread of bacterial infections, especially mites and infectious diseases. After every time you go out, you must remember to disinfect after returning. Often pet clothes, bedrooms, and articles are used. The desktop ultraviolet germicidal lamp irradiates ultraviolet rays to protect your pet from germs.

4) There are mites in the house. Mites are a kind of particularly harmful bacteria, which can be used to break the skin. It is mild if the skin is itchy. In severe cases, it may seriously affect people s health and even disfigurement. According to surveys, the mite infection rate in adults is as high as 97%, especially in pregnant women. If infected with mites, severe cases can cause fetal malformations or miscarriages. Generally speaking, the key to preventing and controlling mites is to keep the house ventilated, dry, clean and dust-free, and also to wash the quilt and bed linen. We can also use the Risente tabletop UV germicidal lamp to regularly disinfect and disinfect household products to ensure that they are prepared.

5) The beriberi virus will be left on shoes, socks, and towels for a long time, which is difficult to kill. Generally, if not treated, it will take several months to cause cross infection. You can use the Risente tabletop UV germicidal lamp, remove the lampshade, reach into the shoes, and perform 360-degree UV sterilization.

6) Household items and personal items, etc.

UV phototherapy is a type of physical therapy and photochemotherapy that achieves the purpose of treatment by ultraviolet light with a specific wavelength. It can directly act on the skin epidermis to kill bacteria, stimulate the defense function of tissues against diseases, enhance the body's immune function, and promote pigment production and desensitization. UV phototherapy technology is used in the treatment of psoriasis, vitiligo, atopic dermatitis, seborrheic dermatitis, mycosis granulomas, pityriasis rosea, pruritus, mycosis fungus (MF), eczema, shingles, folliculitis, Erysipelas, chronic ulcers, skin desensitization treatment, generalized chronic eczema, hand sweat herpes, palmoplantar impetigo, acute severe atopic dermatitis, pigmented urticaria, allergic dermatitis, scleroderma, burns Scars, T-cell lymphoma, cutaneous lymphoma, premature alopecia areata, alopecia areata, lupus erythematosus, tinea capitis, tinea versicolor, red ringworm, axillary hair ringworm, frostbite and other skin rashes have all achieved positive results and become dermatological treatments. Indispensable important means. Phototherapy is the first choice for the treatment of skin stubborn diseases such as vitiligo and psoriasis. The German Waldmann UV series dermatology treatment instrument owned by the Department of Dermatology of our hospital is used for the treatment of skin stubborn diseases such as vitiligo and psoriasis, including narrow-frequency UVB treatment. It can also be widely applied to children and pregnant women.

3. Identification

UV LED technology is suitable for identification purposes, including fingerprint identification and body fluid detection and analysis.

Built-in three batteries, good performance, engineering plastic case vertical, vase shape, convenient, beautiful and practical.

The mini keychain is easy to carry with you. The ultra-violet light lamp shows the clear fluorescence of the Renminbi on the front, and the gold wire on the reverse side of the Renminbi shines. The counterfeit banknotes have no fluorescence or blurred fluorescence, and the reverse lines will not glow. A good helper for the RMB. It can also help identify other products that contain fluorescent anti-counterfeiting marks (such as invoices, train tickets, mobile phones, famous cigarettes, famous wine, cosmetics and other packaging). The principle of the ultra-violet banknote detector is very simple. A large amount of banknotes are added with a special fluorescent material that can be detected through a certain process, which is invisible to the naked eye in sunlight. It displays special fluorescent graphics under the ultraviolet light of the banknote detector. The banknote dispenser uses this principle!

1), ^[1] UV curing principle

UV curing principle: Ultraviolet light (UV) curing is the use of the photosensitizer (photosensitizer) photosensitivity, the formation of excited ecological molecules by photoinitiation under ultraviolet light irradiation, decomposition into free radicals or ions, polymerization of unsaturated organic matter Chemical reactions such as technology and cross-linking can achieve the purpose of curing.

Treatment method of infrared radiation of ultraviolet lamp: Ultraviolet high pressure mercury lamp converts 60% of total power into infrared radiation, and the surface temperature of the lamp tube can rise to 700-800 ° C. In order to avoid overheating of materials, the use of high-power lamps and multi-lamp systems in UV curing devices is valued. Therefore, various measures are generally taken in the device to cool the lamp tube, the reflector lamp cover and the substrate. When used in light-curing coatings, we must try to adjust the temperature. On the one hand, we should avoid overheating of the material, and on the other hand, we must increase the coating temperature. Increasing the temperature is beneficial to the curing reaction. There are three commonly used methods. One is air cooling. This method is the most widely used method at present and the cost is low. The other is water cooling. Adding a water jacket to the lamp tube is effective but the cost is high. Third, add an optical sheet to isolate infrared radiation from the cured product, which is suitable for easily deformable products.

The role of UV curing reflector lampshades

Adding a reflector lamp cover can make full use of the intensity of the UV lamp to the surface of the cured object. The reflection effect of the reflector cover directly affects the quality of the product. The blue sky special lamp company installs imported aluminum alloy full mirror reflectors inside the reflector cover, which is more reflective than ordinary The reflection effect of the film should be increased by 30-40%, and more than 90% of the UV light of the UV lamp can be reflected on the surface of the product to improve the work efficiency.

Several factors affecting the deep curing of ultraviolet radiation

After UV coating is irradiated with UV light, the photoinitiator is triggered to generate free ion groups or ions. These free radicals or ions crosslink with the double bonds in the prepolymer or unsaturated monomer to form a monomer gene. These monomers The body genes begin a chain reaction to generate polymer solid ion molecules, and a complete curing process ends.
