UV curing is currently widely used in special printing, coating, electroacoustic industry, etc. UV curing is actually UV curing. The principle of curing refers to the process of matter changing from low molecules to high molecules. UV curing generally refers to the curing conditions or requirements for adhesives, coatings, inks or other potting sealants that require ultraviolet curing, which is different from heating curing, adhesive curing, natural curing, etc. This change process is called "UV curing".
Principle of UV curing: Industrial UV wavelength has an application range of 200nm to 450nm. The process of using UV to irradiate "UV curable materials" to harden them is called "UVCuring Process".
It is important to choose the appropriate spectrum and curing time. Commonly used UV ultraviolet bands are divided into UVA, UVB, UVC, UVV and other bands, among which the UVA band is the most commonly used. Select the corresponding glue in the corresponding band UV curing machine Light source is an important process for improving curing efficiency. In addition, if you want to improve curing efficiency, you also need to consider the light source intensity, temperature, power, irradiation time and other factors of the UV curing machine. Choosing appropriate parameters is a must for curing.
During curing, it is necessary to control the intensity, energy and time, how much intensity of light is needed, how much energy is needed to make the curing shape, how long it takes, etc. A UV energy meter is needed to monitor the product curing and record the data. Comparative analysis of the time, energy and intensity required each time makes a fixed plan to monitor the machine operation. The energy is the cumulative value of intensity and time. As time changes, the energy will also change accordingly, so when comparing the energy, be sure to make sure it is within the same time. In addition, the ultraviolet light source is easy to attenuate, and it is necessary to return to calibration after using it for a period of time.
