[Matching] Matching of UVLED Ink and UVLED Light Source

The promotion and use of UVLED ink has greatly solved the problem of not drying in high -speed printing materials such as heat -sensitive paper and other special printing materials. However, due to the different characteristics of the materials, it is still found that there is a bad drying phenomenon when using the UVLED ink during production. why? This is because the matching of UVLED ink and UVLED light source. 1. UVLED ink 1. The UVLED ink is under the irradiation of UVLED light, an integrated aggregate reaction, and instantly solidified into a film ink. It is mainly composed of optical polymer prefabricated, photocopic monomer, optical aggregates, organic pigments and additives. Among them, light aggregates are one of the most important part of the entire UVLED ink, and the beginning of the optical aggregation reaction. Commonly used light aggregates include aromathe ketone and puppet marriage ether. 2. Features (1) Dry instantly at low temperature; (2) good gloss, high adhesion; (3) no solvents, good stability; (4) strong printing adaptability, meeting the needs of multiple marks; (5) save saving Energy, improve efficiency; (6) Little environmental pollution. 3. Under the irradiation of UVLED light, the light aggregates in the UVLED ink absorb a certain wavelength of photon energy, which stimulates the stomach, and forms a free base or ion. Then through the transmission of energy between molecules, polymer prefabricated and sensitivity monomers such as polymer and sensitivity monitors become excited, generating charge transfer collaterals. 2. UVLED light source 1. Constructing UVLED light source is a device that emits UVLED light in the UVLED curing system. It is usually composed of UVLED light heads (UVLED shots), UVLED controllers, and cooling devices (necessary cooling methods) and other components. Its performance parameters are mainly: peak wavelength, peak illness, radiation area, radiation distance, cooling method and service life, etc. 2. Spectrum characteristics UVLED light sources Although the main is ultraviolet light, it is not a light in the band, but a single wavelength light. The wavelength is wide. Different UVLED light sources, the peak wavelength of the launch light is also different. According to different application needs, the peak radiation degree presented can be different.
