Do You Know UV Drying Machine?

1. What is a UV drying machine?

UV drying machine is a kind of curing and drying principle machine based on the characteristics of ultraviolet rays. This machine is characterized by fast curing and drying, convenient operation and so on. Ultraviolet is an umbrella term that refers to radiation in the electromagnetic spectrum with wavelengths between 10nm and 400nm. Shortwave UV is a type of UV light with a wavelength in the range of 200 to 280nm. It has a bactericidal and destructive effect on human cells. The light from low-pressure mercury lamps is much richer.

Curing solid UV rays can have damaging effects on the eyes and skin. The 80W/Cm curing lamp emits white light, which is stronger than that of an electric welding machine. When you look directly at it, you will be dazzled. Generally, you will not feel glare when you see blue reflected ultraviolet rays, but it is also harmful to stare for a long time. The UV drying machine is beneficial to the processing of products, such as the painting and drying of components, and the color curing of product mold planting.

2. Matters needing attention in the use of ultraviolet dryer

The UV drying machine for sale has a curing drying principle mechanism based on the characteristics of ultraviolet rays. This machine is characterized by fast curing and drying, convenient operation and so on. The internal light source of the ultraviolet dryer will decay after a period of use. You must use the UV energy meter LS131 to estimate whether the light source is still valid at this time, and replace the modulation tube in time if the light source is attenuated.

Ultraviolet light with a wavelength of less than 210nm passes through the air and produces ozone. The allowable ozone concentration is 1.5 PPM. It has a bactericidal effect, and the ozone concentration below 1.5ppm can eliminate bacteria in the respiratory system. However, we cannot inhale ozone for long periods of time. Otherwise, it will cause respiratory mucosal lesions. Therefore, we need to pay attention to some precautions when using it:

First of all, don't let the ultraviolet light of the ultraviolet dryer leak, the unstoppable ultraviolet light can only be released after more than 3 reflections, and the direction of light leakage should not be aimed at the operator - use a suction fan with a reasonable air volume to suck out the ozone near the modulator, to prevent ozone production.

Photosensitizers, sensitizers, and diluents in materials cured by UV drying machines are comparative substances of different wavelengths for UV sterilization. It can irritate human skin to varying degrees. If it comes into contact with the skin during use, it should be washed with soap immediately, especially in summer. There are many factors that affect a UV LED curing system when using a UV drying machine. Therefore, a large number of equipment for ultraviolet curing have been produced.

The intensity of the light source is especially important. The internal light source of the ultraviolet dryer will decay after a period of use. You must use the UV Energy Meter LS131 to estimate whether the light source is still active at this point. If the light source is dimmed, the curing machine will run more easily.
