How to choose the material and shape of the UV Accelerated Weathering Tester reflector?

The UV Accelerated Weathering Tester generally uses a focusing type reflector. The structural feature of this reflector is that the reflected UV light energy is concentrated, and the light curing efficiency is high, which is conducive to the curing of the thick ink layer and can completely cure the deep layer of the ink.

What should be noted on this side is the choice of material and shape of the reflector.

1. Material selection

Be sure to choose aluminum, not iron or stainless steel for cost savings, because stainless steel will turn black at high temperatures, and after turning black, it will not only not reflect light, but also absorb light. The most reflective effect is the mirror-surface alumina plate, whose reflectivity can reach more than 80%, thereby greatly improving the efficiency of ultraviolet rays.

2. Shape

The shape of the reflector is to ensure that the UV light can be gathered together, so the shape of the semi-circular arc is the best choice. Also pay attention to the erection position of the UV lamp to ensure that it is in focus. In addition, the reflector is an important channel for heat dissipation of the UV lamp, so the outside of the aluminum cover should be processed into a radiator to increase the heat dissipation area.

The reflector plays a very important role in the UV fixed telephone device. Some manufacturers tend to ignore its role, and use some substitutes to act as reflectors, or even do not install reflectors, so that 40%-50% of the ultraviolet energy of the UV lamp is wasted. The response of some manufacturers is to blindly increase the power of the UV lamp, which will not only fail to fundamentally solve the problem, but will also cause greater waste of electricity.
