Curing Principle and Power Calculation of UVLED Curing Equip

UV Curing Principle

 

 

 

With the continuous development of UV technology, many customers who have not contacted the UV LED curing machine before are willing to replace the traditional mercury lamp production line with the UV LED curing production line. UV curing refers to the addition of photoinitiator (or photosensitizer) to the resin of special formulation, which can absorb the high intensity ultraviolet light in the ultraviolet (UV) curing equipment, and then produce active free radicals, which can initiate polymerization, cross-linking and grafting reaction, so that the resin can be converted from liquid to solid in a few seconds. At present, the main UV curing equipment on the market is UV LED curing machine and UV mercury lamp.

 

 

 

 

Main parameters of UV LED curing machine

 

 

 

Four key parameters of UV LED curing machine are:

 

 

 

1. UV Wavelength

 

 

 

2. Irradiation Intensity

 

 

 

3. Irradiation area

 

 

 

4. Curing speed

 

 

 

Effect of Related Parameters on UV Curing Quality

 

 

 

1. UVLED curing machine wavelength: 365 nm band spectrum is suitable for general light-curing ink (not suitable for ice, wrinkle and other special spectral requirements of ink). It is suggested that customers should carry out photosetting test before choosing UV LED curing machine to check whether the wavelength of UV curing equipment meets the requirements of photosetting.

 

 

 

2. Power of UV-LED curing machine: High power of UV-LED curing machine will cause ink embrittlement, and low energy can not achieve photosetting effect, so the light intensity power of equipment needs to be tested strictly.

 

 

 

3. Heat dissipation device: UVLED curing machine emits ultraviolet radiation, but also generates a lot of heat, which makes the temperature of the body rising. The current UVLED curing machine of Yuntong Science and Technology is divided into two types: air-cooled heat dissipation and water-cooled heat dissipation. Generally, air-cooled is suitable for curing UV glue and water-cooled is suitable for curing UV ink.
