Brief introduction of UV system knowledge


Ultraviolet is short for ultraviolet, that is, ultraviolet, and ultraviolet lamp tube is short for UV system. The spectral range of industrial UV source is 200-450 nm, with 365 nm as the center. According to the different bands, the lamp tubes are divided into uv-a, UV-B and uv-c, which have different uses. Among them, UV-A can be seen with the naked eye, while the others can not be seen with the naked eye.


Scope of application

1. Spraying: plastic spraying companies such as general mobile phone case spraying, cosmetic case, MP3 small household appliances case are mostly used. Mobile phone case spraying and UV printing industries have different requirements for uv, depending on their products and equipment. Mobile phone shell spraying companies, most of which have 6-8 lamp tubes (in a painting line) as long as the parameters provided are correct, as long as the specifications and parameters of his UV system are known, can be replaced.

2. Printing: screen printing, offset printing and 5-color printing are mostly used. For example, U-disk and CD-ROM, they use UV protective glue. When printing on CD-ROM, they also use UV ink for screen printing. In screen printing, most of them now use UV ink for printing. With fast drying, good adhesion, all kinds of performance up to standard (adhesion, wear and friction, etc.).

3. Footwear industry: Ultraviolet irradiation is used to irradiate the material of sole, making it react chemically, so that the adhesive has good affinity with the sole and upper. Footwear industry, suitable for gluing, UV glue for plastic bonding, like the hospital infusion of plastic pipe bonding. Generally speaking, companies that make high-grade tourist shoes can use them. The business of this industry is based on technology.

4. Wood industry: only surface coating, because UV paint (gloss oil, etc.) has good performance in all aspects: such as wear resistance, acid and alkali resistance, weatherability, etc., after UV coating, can make wood flooring and other surface glossy and gorgeous feeling. In wood painting, most of the lamps used are longer in length and more powerful in length of about 1000mm. 5. pcb, LCD industry: PCB is a circuit board UV system used for printed circuit boards, generally using L (metal halogen lamp), another kind of exposure lamp is also a metal halogen lamp PCB production, used for exposure and development, generally used in circuit board companies. LCD is a display screen, generally used low-pressure cold ultraviolet lamp and curing lamp are different, but belong to ultraviolet lamp, use is different.

5. Handicraft polishing: As long as the handicraft is used for UV polishing oil, UV ultraviolet lamp tube can be used.

6. UV automatic coating line: The pretreatment project uses electrostatic precipitator gun or electrostatic precipitator rod to deal with, that is to say, corona treatment, because plastic, plastic material, its surface tension is very poor, after corona treatment, the surface tension of its surface is increased, in order to strengthen the substrate and uv. The affinity of coatings, so that there will be better curing effect, if the pretreatment is not good, the adhesion of products will also be a problem, many not the cause of the lamp, but equipment or operation process problems, and, UV paint or ink, also has a great relationship.

8. Medical Devices Industry: In the production of medical devices, UV irradiation is used to irradiate the UV bonding part to make it react chemically, so that the bonding adhesive has a good affinity with the fitting surface. It has fast drying and good adhesion. Most of the lamp tubes used are long in length, and most of the power in 1000W is about 1000mm in length. The time ranges from 15 to 20 seconds and the wavelength ranges from 350 to 450 nm. As mentioned above, UV spraying company is to be jointly served by: UV equipment manufacturer, UV system manufacturer and UV coating company.
