UV light source selection and equipment application

The lighting process of the arc discharge lamp is connected to the transformer circuit, and the transformer output is open circuit, generating an electric field at both ends of the lamp. Under the action of the electric field, the positive electrode of the electrode emits electrons, and the inert gas in the electronic lamp collides with and stimulates to generate more electrons, and collides with mercury or a metal halide to cause a light emitting body in the form of an excitation discharge.

It can be said that the UV lamp power should be selected according to the width of the cured product multiplied by the UV lamp power density, but depending on the speed of the printing press and the quality of the printed products, choose to install a few degrees of lamp, when the lamp power After selection, the selection of other parameters shall be determined by W=UL (U is the lamp voltage and L is the operating power supply). General situation I≈8A. When selecting the current, the current should also be selected according to the printing product and the internal conditions of the printer in order to determine the voltage parameters.

The choice of transformer power is directly related to the UV intensity of the output of the UV lamp. The UV lamp uses a magnetic leakage boost transformer. Because the UV lamp or metal halide lamp is an arc discharge. The light intensity is changed by the lamp current. If the transformer parameters do not match the lamp parameters, the UV content is low (unstable) and the service life is short. The transformer magnetic field circuit divides the main flux and leakage flux. The main flux circuit is a circuit that transfers energy efficiently (through the iron core to store energy). The leakage flux is part of the coil back to the bottom, and part of it is released to the outside to generate negative helium, such as causing vibration of the surrounding iron cabinet or iron gas. If the leakage magnetic flux is large, then the energy from the primary side to the secondary side is effectively transmitted and the output energy of the transformer is reduced. The effect is that the output current is reduced and the voltage does not change. When the silicon steel sheet is added to the leakage magnetic field path to short-circuit the leakage flux and increase the leakage magnetic flux, the current can be adjusted by this method.

We are based on the matching principle of transformer and light source. After repeated scientific research and experiments, the technical personnel of the company make adjustments on the electrical parameters of the power supply and light source, so that in the curing equipment, as long as it is used with the company's use of electric light source products, it can make the curing process not only increase the speed but also improve the degree of curing. , And can extend the life of the light source.

UV light source is an environmentally friendly curing light source that has rapidly developed in recent years. Its main components are radiant energy sources with mercury lamps and reflectors, cooling fans and barrier components. It quickly occupies the market with instant curing, free of volatile solvents, and easy application. Compared with the traditional thermal curing, it has the advantages of high quality, low energy consumption, no thermal aftereffect, and ready use after curing. Since the company sold UV light source UV equipment, the product quickly obtained the use of manufacturers and market recognition. And gradually improved in practice, making the company's products faster, more convenient and more reliable service for the UV business.

The production light source must fully grasp its high-tech characteristics. Ultraviolet radiation generated by UV light sources can only account for one-third of the total, and two-thirds of them are converted into heat energy. And UV radiation is not a single wavelength of light, but a different UV light source in a band, the wavelength range of the emitted light is not the same. The energy distribution of the spectrum in the light source is also different. The gas discharge lamps used in the current market are basically high-pressure mercury lamps.

The intensity of the light source distributed by the company reaches the specified spectral range, and its production process is currently relatively advanced in Europe and the United States. In this industry, in particular, it is in accordance with strict industry standards and technical standards. From the choice of materials, processing, aeration, quality inspection, and packaging, we have striven for the highest quality in the European and American industries, and we have continuously improved and improved our processes and packaging.

In the absence of any blocking and filtering, the gas discharge lamp has 80% of ultraviolet rays diffused in the surrounding area. To focus all ultraviolet rays in one direction. Ultraviolet devices must be equipped with light reversal devices. There are generally two types of reversing devices, parallel and focus. The parallel reflection device will form a uniform parallel light, and the focused radiation device will form focused light focused on the focus.

In practice, we have found that in order to ensure the focus of the light, scientific choice of lampshade and reasonable adjustment of the angle can greatly improve the use of the light source in curing. The company's technical personnel have scientifically calculated and tested and developed their own molds, which are matched with self-manufactured lamps. The light source, power supply and lampshade have a good effect in the user's use, and have been widely used in the curing industry of the printing industry, the coating industry and various cosmetics and daily necessities.
