Traditionally, the curing process equipment uses a UV mercury lamp, that is, an ultraviolet curing mercury lamp. The life of this lamp is only 500 to 1000 hours, plus it needs to be preheated before each use, so the actual effective use time is far lower In 500 hours. Moreover, the traditional mercury lamp will generate a lot of heat and infrared rays, which will damage the coating, so it needs to use a longer working distance, which reduces the use efficiency; and a large amount of heat and infrared rays lead to high heat in the system, which requires a cooling system and air conditioning equipment. Coupled with the huge equipment volume, high energy consumption, short life, mercury content, and ozone generation, these are the shortcomings of traditional UV curing mercury lamps.
With the improvement of UVLED brightness and the maturity of technology, and the general increase in environmental awareness in recent years, curing process equipment has accelerated the introduction of UV LEDs, and the demand for UV LEDs to replace UV mercury tubes is expected to grow at a higher rate. Compared with UV mercury lamps, UV LEDs have higher efficiency, stable energy, low power consumption, long service life and environmental protection. In recent years, more and more manufacturers have begun to require UVLEDs in curing equipment. For UV mercury lamps, if Apple has requested that the suppliers that it cooperates with have curing machines, they must be converted to UV LEDs. Therefore, companies such as Chenhong have completed the conversion of this product; and it is reported that Hon Hai It has also been evaluated. However, when the curing equipment is switched to UV LED, the lighting energy and efficiency are also different from traditional UV mercury lamps. Considering factors such as adhesion and yield, the use of related inks and glues must also be formulated Adjusted.
Due to the environmental protection advantages of UV LED, there has been a trend of increasing temperature in replacing traditional UV mercury lamp tubes in recent years. In the Japanese market, in addition to the With the increase in the use of imports, it is estimated that in the mainland, Taiwan and other places, better demand development can also be seen in recent years.
