As we know, the Dongguan UV tube plays a very important role in many fields of industrial production, is one of the necessary equipment of automation products, to say to the next is how to select the UV lamp power.
First understand a concept: the power UV light is radiant energy UV light, also known as penetration. It must meet the UV ink (light oil) absorption wavelength and power density requirements.
The maximum life of the UV lamp is 800— 1000 hours after that, to replace the intensity of ultraviolet light, UV lamp to this period because of the launch of the weak, will affect the curing effect.
The UV lamp power to meet the requirements of 80 ~ 120W/cm, but the greater the power of heat will be greater, so according to the curing and curing rate to choose different power.
If the UV lamp power is not enough, even if the illumination time is long, the number of UV curing device more products also fail to completely cure; on the contrary, if the low power UV light can not penetrate the ink layer at the bottom, so that the bottom is not curing is not sufficient, but also make the UV ink (light oil) surface aging and closed, become brittle, and ink (light oil) adhesion is not good, will cause the superimposition of the interlayer binding force difference.
In view of the above problems, but also it is recommended to use period according to the production environment (dust content in air), the reflection cover plate surface with anhydrous ethanol cleaning tube surface and the reflection at the appropriate time, and the UV lamp 90°. This is conducive to the UV - ray radiation to all UV ink or varnish, guarantee a certain penetration.
You said this about the UV lamp power choice, I hope the above information will help you, Dongguan Qingda ultraviolet technology as a professional development and production of professional UV light manufacturing enterprises as a whole, is a famous China UV machine, UV light curing machine, UV light, UV lamp, UV lamp power supply is one of the production enterprises, to provide customers with UV light source assembly and installation of production plan, but also can provide the whole line, give full play to the development and application of UV light curing technology in various fields, I hope to share with you!
