Workingprincipleandcharacteristics of UV oven:

I. UV curing principle:

 Adding a photo initiator (or photo sensitizer) to a special formulation of the resin,after absorbing the high intensity ultraviolet light in the UV curing equipment, the activated free radicals are generated, thus triggering polymerization, cross-linking and bonding reaction, so that the resinink/paintcan be changed from liquid to solid in less than 1 second.

II. UV curing lamp:

1. At present, the light source of UV equipment used in industry is mainly gas discharge lamp .According to the pressure of the gas in the lamp cavity, it can be divided into low pressure,medium pressure, high pressure and ultra-high pressure.

2.High-voltage lamps can generate characteristic ultraviolet (UV), visible light and infrared (IR) with strong radiation at 310nm,365nm and 410nm, among which 365nm is the main peak wave length, which is commonly used in countries around the world to solidify dry baths (UV lamp refers to the high-pressure lamp at 365nm).Because the spectrum of 365nm band is suitable for commonly used photo curing ink/paint, it is necessary to conduct photo fixation test before selecting common UV photo fixation equipment to check whether the wavelength of UV machine meets the requirement of photo fixation.

3. The reasonable refraction of UV light source and the stray light filtration of UV lamp tube are quite important,otherwise it will affect the photo fixation effect.

4.Generally, the power required by UV machine forink/paint fixation is 80-120w/cm. Too high light setting energy will cause the brittle ment of ink/paint,and too low light setting energy will not achieve the light setting effect.

5. At the same time of sending out ultraviolet UV lamp,also can produce a lot of heat, make the body temperature rising, so over the UV lamp light solid machine is equipped with convulsions device is necessary, and through the ventilation pipe will be produced in the process of curing ozone emitted to achieve cooling, so as to adapt to the work of temperature or thin coating to demand higher work..

III.Main features of our UV oven:

1. The oven works as a whole, with beautiful appearance and light volume, saving space.

2.Equipped with professional lamp tube power and imported light source reflector for maximum UV light refraction.
