1.Different solvents, the light-curing ink dilution monomer is involved in the chemical reaction, its molecular weight is large, so the ability to reduce viscosity is limited. And ordinary ink solvents do not participate in the reaction of 100 percent volatilization, but can greatly reduce the ink viscosity.
2.The influence of pigment. The pigment of UV LED ordinary ink hardly affects the drying speed. Ink of different colors is composed of different pigments, the same substrate and the same auxiliary agent. But UV LED light curing ink situation is different, because different colors are on different wavelengths of light selective absorption and conditional reflex, so different color printing ink curing speed.
3.All visible light is fully reflected and requires high energy. Black absorbs all of the light in the theory, but to the light shade effect, because of pigment particle hinders ink curing deep, UV LED also needs higher energy, that is why the curing speed lower.
4.UV LED cold light source and ink are closely related. Whatever UV LED exposure area, light intensity and son on have a great relationship with ink. Long service life, LED life is up to 20,000 hours, reduce the cost of consumables.
5.Security monitoring camera UV glue adhesive small parts, UV LED label printing surface light source, according to practical application of customers, customized UV LED surface light oven.
6.UV LED Oven is a cold light source, no thermal radiation, the temperature of irradiated products is almost constant.
