The core technology of [UV LED photocuring] includes UV coating, ink material and formulation technology, and UVLED curing system, which complement each other.
UV LED coating, ink formulation technology and mercury lamp matching paint, ink after decades of development, has been quite mature, although the conversion to LED light source, its curing principle is similar, but will still face some technical problems, need to be further developed and solved, which is urgently needed to solve the following three problems. The first is an efficient, yellow-free and economical photoinitiator that matches the UVA spectrum. The second is low-mobility coatings and inks that can be used in food packaging and meet standards. Third, UV LED curable coatings with adhesion and other physical properties comparable to heat curing coatings.
UV LED curing system technology UV LED curing system is generally composed of UV LED curing lamp and drive control system, which is a knowledge-intensive product involving many disciplines. Its core technology includes optics and packaging, heat transfer, power electronics and other links, and defects in each link will greatly affect the quality and overall performance of the product.
To do a good job of UV LED curing system, it is generally necessary to equip structural engineers, heat transfer and fluid engineers, packaging engineers, optical design engineers, software engineers, electronic power engineers, electrical engineers and other R & D teams. The biggest difference between the UV LED industry and the traditional mercury lamp industry is that UV LED belongs to semiconductor products, technology development is particularly rapid, is no longer a product to eat ten years, a technology lifetime state, but the need for continuous research and development investment, keep up with the trend of technological development, otherwise it will soon be eliminated by the market.
In the iron printing industry, UV LED curing lamps require the highest possible UV irradiation intensity at 25~50mm irradiation distance, which puts higher requirements on optical design.
Using a reasonable optical design, you can use less power consumption to achieve the same UV irradiance, or use the same power consumption to achieve higher UV irradiance, which is of great significance for energy saving and ensuring curing quality.
The trend from UV curing to UV LED is indisputable. With time and case studies of successful implementation of UV LED conversion companies, successful conversion of UV LED will no longer be a problem. For UV LED technology and the iron printing industry, there are greater opportunities in the future, reflected in the following aspects.
First of all, change the printing method of “coating + drying room” to the printing method of “coating +UV LED”, white cotin and light oil coating to achieve UV LED curing, further significantly reduce production costs and greatly improve production efficiency.
Secondly, the offline production method is changed to the online production method, white cotin + color ink + gloss oil, all through the continuous online production of UV LED curing, greatly improving production efficiency.
Third, the future of printing equipment, ink/paint, UV LED coordination between the three parties will be more and more close, with the introduction of the new process, printing iron production will be subversive changes.
Fourth, to further solve the contradiction between the overall radiation intensity of the UV LED system and the reduction of system power consumption, to achieve higher UV energy output with lower system power consumption.
The implementation of a new technology always encounters various problems in the early stages. There is no doubt that UV LED technology is worth our persistence and can not give up.
The practice of UV LED curing in the iron printing industry, applied to ink curing is no longer a problem, I believe that after a period of improvement and improvement of the ink formula, it will reach the best balance between quality and economy. And the new challenge and opportunity, that is, white cotin and UV LED curing coatings, will be the next wave of iron printing industry application hot spot!
