Principles and application prospects of UV curing

Date:Jan 25, 2021

UV is the English abbreviation of Ultra-VioletRay. Industrial UV wavelengths range from 200nm to 450nm. The process of using uv to irradiate "UV-curable materials" and harden it is called "UVCuring" Process".

The principle of UV curing is to irradiate special glue with ultraviolet rays to cause the glue to polymerize and cure. But choosing the right spectrum and curing time is particularly important. The commonly used UV ultraviolet bands are divided into UVA, UVB, UVC, UVV and other bands, of which the more commonly used is the UVA band. Corresponding glue to choose the UV curing machine light source of the corresponding band is an important process to improve the curing efficiency. In addition, if you want to improve the curing efficiency, you need to consider the light source intensity, temperature, power, and irradiation time of the UV curing machine. Choosing the right parameters is a necessary condition for curing. Traditional oven-type glue curing solutions are already facing challenges. The long curing time and low-precision curing make it difficult for many manufacturers to increase the added value of their products. High temperature also poses challenges to many products. The high imitation characteristics have also made the industry linger. At the low end. People urgently need a new curing program, and UV curing program came into being.

UV curing machine market application prospects: as a new curing program, its advantage is that the curing time is short, which can significantly improve production efficiency. Compared with traditional oven curing, it also has environmental protection characteristics. Traditional oven curing will produce a large amount of formaldehyde, and the toxic gas emitted will endanger human health. The UV curing machine does not produce any toxic substances and is an ideal glue curing solution. However, if ultraviolet rays are directly irradiated to the human body, it will endanger human health. Therefore, protective measures should be taken in production or life applications to avoid the harm caused by direct ultraviolet rays to the human body.
