  • Different Kinds of Ink
    Different Kinds of Ink
    2018-04-28

    The biggest difference between water-based ink and solvent-based ink that water-based ink uses water instead of organic solvents, which significantly reduces VOC emissions, does not effect the health of human body, is not easy to burn. The UV ink is stable. The color is bright. The plate is not corroded. The operation is simple. The price is cheap. After printing, the adhesion is good. The water r...

    Special Application of different wavelength of UV LED, VIS LED, Infra LED
    2018-04-18

    UV LED 1.Low UV: 250nm-265nm-285nm-365nm. Now, it has reached 250nm-410nm. Both of them are INGaN/GaN material carbide. The UV rays can kill all bacteria in the water, which the lethality can reach 98%, especially 285nm. 2.Mid UV: 365nm-370nm. Both of them accord with international standard. UV has kill-ability. In general, doctors are required with no bacteria when they operate. The UV of 365nm-3...

    UV LED Has a Good Development, The market of Ultraviolet Lamps will Soar
    2018-04-17

    LED bulb can develop visible and invisible light by adjusting the chip wavelength. For UV LED, because its overall cost is low, becomes one of the development drivers of ultraviolet lamps. According to the estimation of industry experts, composition annual rate of growth of ultraviolet light market, between 2017~2021, will reach 13.32%. Traditional ultraviolet lamps has the limits of space and lig...

    UV Radiation Curing - New technology of Surface Curing
    2018-04-13

    Ultraviolet radiation curing technology is an entirely new green technology developed since the 1970s. It is used to produce UV curing coatings, or UV coatings. With non-volatile organic compounds (VOC), small environmental pollution, fast curing speed, energy saving, good performance of cured products, suitable for high speed automatic production and other advantages. However, traditional coating...

  • Important Role of Wavelength
    Important Role of Wavelength
    2018-04-09

      Most UV curable contains two wavelengths that work at the same time (if you include IR,3). Short wavelengths work on the surface, long wavelengths work in ink or coatings. The theorem is that short wavelengths are absorbed on the surface and cannot reach deep results. Shortage of short wave exposure can lead to sticky surface.Long wave energy deficiency can lead to adhesion. Each recipe and...

  • Eight Questions about UV LED
    Eight Questions about UV LED
    2018-03-31

    Ultraviolet (UV) radiation has been used for many years in the industrial and health field. Nowadays, the new generation of LED appears to be challenging traditional sources of UV fluorescent lamps. 1.What is the wavelength range of UVC LED? The UVC LED wavelength is usually defined as 200nm to 280nm. 2.What is the “sterilization range” of ultraviolet light? According to the International UV Assoc...

    The Development of Chinese Optics (Ⅰ)
    2018-04-12

    In 1948, when Mr. Wang returned to China, the old China had only small workshops and some capable craftsmen to repair or assemble the optical instruments on the guns. At that time, the only optical factory is in Kunming, Yunnan, named after the state-owned 298 factory, about 500to 600 people. They mainly serviced for weapon and guns, can make some simple military optical instruments, such as binoc...

    The Development of Chinese Optics (Ⅱ)
    2018-03-30

    (Continue The Development of Chinese Optics (Ⅰ)) The development of Chinese optics mainly depends on the "scientific talents" cultivated by itself. In 1952, Mr. Wang was transferred to the Changchun headquarter science academy instrument pavilion (by Changchun optical machine institute) work. A few years the institute had been assigned to hundreds of the optical professional graduates, is Chinese ...
