The invention discloses LED four-color printing ink for intaglio printing and a preparation method of the LED four-color printing ink. The technical scheme is characterized in that the LED four-colorprinting ink is prepared from components in percentage by weight as follows: 8%-10% of pigment, 25%-30% of a resin connecting material, 50%-55% of acrylate monomers, 5%-10% of a photoinitiator, 1%-1.5% of a wetting dispersant, 3%-5% of packing and 0.3%-0.8% of a leveling agent. According to the LED four-color printing ink for intaglio printing, a cured ink layer has bright luster, full color and clear lines, continuous printing is realized without stopping, and the ink layer is good in surface leveling property and high in lustrousness.

The invention discloses an ultraviolet light-cured offset printing ink with LED as a light source. The ultraviolet light-cured offset printing ink comprises, by weight, 20 to 30 parts of pigment, 55 to 75 parts of radiation-cured resin, 1 to 7 parts of a photoinitiator, 0 to 3 parts of wax, 0.1 to 5 parts of an active diluent and 0.5 to 4 parts of an auxiliary agent. The UV-LED light-cured printing ink has the following characteristics: the printing ink is applicable to offset printing; electric energy consumed in curing is about 1 / 4 of electric energy consumed by a common ultraviolet lamp; emission of CO2 is substantially reduced; ozone is not generated; etc. The printing ink is completely dried under the printing condition of a curing speed of 40 to 200 m / min and enables printed lines to be clear; and after curing, each performance index (adhesion, friction resistance, chemical resistance and the like) of the printing ink accords with requirements on printing of securities.

The invention relates to a method for eliminating static by photoion and pertains to the field of static. The filament of the X-ray tube in the method adopts an adjustable direct-current preheat starting / working voltage or current and an X-ray tube with an annular anode, an end window launching structure and a large launching angle is taken as the X-ray generating source. The filament of the X-ray tube is connected to a positive direct-current starting voltage / a high direct-current working voltage, wherein, the cathode is fixedly connected with the filament. The anode of the X-ray tube is grounded. Soft X-rays are generated by the X-ray tube. The soft X-rays ionize the air around the substances on which the static is eliminated, so as to generate an ion halo with symmetrical positive and negative ions on the surface of the substance, thereby neutralizing the static charges on the surface of the substances on which the static is eliminated. The invention further provides a device for eliminating static by photoion. The X-ray of the device has larger output power, lower power consumption and excellent radiating effect, can be continuously used for a long time, can eliminate the static fast and has a wider application range. The device can be adjusted according to different substances / objects on which the static is eliminated, so that the quantity of X-rays emitted can achieve the best static eliminating effect.

The invention discloses a human-machine coexistence ultraviolet LED irradiation system aimed at sterilizing the air in the upper layer of the space. In the equipment casing; the ultraviolet light source assembly includes an ultraviolet LED lamp bead, a package base and a circuit board, the ultraviolet LED lamp bead is packaged in the package base, and a plurality of package bases are installed on the circuit board; the irradiation angle controller drives The circuit board rotates to adjust the radiation angle of the UV light source. The louver structure is installed on the radiation outer surface of the housing to further collimate the radiation angle; the sterilizing equipment of the present invention is easy to adjust the radiation angle to provide a radiation field suitable for various ceiling heights, and can be applied to buildings with high floor heights, such as fitness, sports venues, or venues such as indoor performances.
