Traditionally, the curing process equipment uses UV mercury lamp, that is, UV curing mercury lamp. The service life of this lamp is only 500 to 1000 hours. In addition, it needs to be preheated before each use, so the actual effective service time is far less than 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, thereby reducing the use efficiency; In addition, a large number of heat and infrared rays lead to high system heat, which requires the matching of cooling system and air conditioning equipment. In addition, the huge volume of equipment, large energy consumption, short life, mercury content, and ozone generation are the disadvantages of traditional UV curing mercury lamps.
With the improvement of UVLED brightness and the maturity of technology, as well as the general improvement of environmental awareness in recent years, the curing process equipment accelerates the introduction of UVLED, and the demand for UVLED to replace UV mercury lamps is expected to grow at a higher speed.
Compared with UV mercury lamp tubes, UVLED has the characteristics of higher efficiency, stable energy, low power consumption, long service life and environmental protection. In recent years, more and more manufacturers have begun to require UVLED to replace UV mercury lamp tubes in curing equipment. For example, Apple has asked its suppliers to convert all of them to UVLED if they have curing machine equipment. Therefore, Chen Hong and other manufacturers have completed the conversion of this product; It is reported that Hon Hai has also been put into evaluation.
