Through the development of [UVLED curing] finished products in recent years, whether it is the screen printing industry or the offset printing industry, the use of UVLED curing ink is more and more. As we all know, compared with traditional solvent-based inks, UVLED cured product curing ink has the advantages of good gloss, strong three-dimensional sense, no harmful solvent volatilization, especially in the drying of ink, UVLED cured product ink can be instantly cured under ultraviolet irradiation, avoiding the traditional solvent-based ink drying cycle long, large footprint and other shortcomings. Greatly improve the work efficiency and quality. UVLED light curing ink after printing need to be UV light solid equipment to achieve instant curing.
First, UVLED curing product curing principle:
UVLED cured product curing process: A photoinitiator or photosensitizer is added to a specially formulated resin, and after absorbing high intensity ultraviolet light in ultraviolet (UV) photocuring equipment, active free radicals are generated, which leads to polymerization, crosslinking and grafting reactions, so that the resin is converted from liquid to solid state in a few seconds.
Two, UVLED cured product inkjet printing advantages:
In the past, ultraviolet light sources used in the printing industry generally used high-pressure mercury lamps and metal halogen lamps and other light sources, due to the large size of lamps and power devices, users are worried about the power consumption and heat caused by the printing press and substrate damage and ozone generation in the process of use. With the advent of curing technology of UVLED curing products, due to its environmental protection characteristics, environmental pollution relative to solvent-based smaller, and the operating cost and solvent-based equivalent or even lower, so more and more attention.
UVLED light curing technology is a new technology of green industry, has been rated by the North American radiation curing Committee with “5E” characteristics of industrial technology, fully showing the characteristics of the technology, that is, high efficiency, energy saving, environmental friendly, economic, wide adaptability. At present, UVLED curing lamps commonly used on the market are generally mercury arc lamps, referred to as mercury lamps, UV mercury lamps have a limited service life, and large energy consumption but effective use of energy is not high, in addition, although UV mercury lamps relative to solvent-based inks, due to the absence of VOC emissions and environmental friendly characteristics, but UV mercury lamps also have some hidden pollution. For example, it is easy to produce ozone, which has a greater impact on health.
The above explanation is the relevant common sense of UVLED curing products. Auvcure is a professional manufacturer of all kinds of UVLED point light source, [UVLED line light source], UVLED surface light source and [UV curing machine], and can provide solutions and customization according to the actual needs of customers. The company has Japanese production technology, products are exported to South Korea, Japan, the United States, Brazil and other places. Welcome friends from all walks of life exchange guidance.
