Many friends are a little confused about the actual use of UV glue, but they can't find much valuable related content on the Internet. Today, Height-LED analyzes the causes of incomplete curing of UV glue from two aspects of UVLED curing machine and UV glue.

Analyze the main reasons for the incomplete curing of UV glue:

1. At present, the wavelengths of UVLED curing machines on the market are generally divided into 365, 395, and 405. The wavelength rate requirements of UVLED curing machines may also be different in different UV glue formulations. If the UV glue cannot be cured after being irradiated for more than a few minutes for a long time, it may be a problem with the light source. It is recommended to replace the UVLED curing machine with a different wavelength.

2. Some UV glues require a lot of energy absorption. If a UVLED curing machine with too low power is used, the curing speed may be very slow or even impossible to cure. In this case, please check the power of the UVLED curing machine, and replace the equipment with higher power if necessary.

3. The light source of UVLED curing machine is aging or damaged, resulting in energy attenuation. The light intensity can be detected by an energy meter, and the attenuation equipment should be replaced in time.

4. The adhesive material is not light-transmitting/light-transmitting, causing the UV light to reach the glue part to attenuate or not penetrate, especially in the interior and gaps. It is recommended to change the irradiation direction, or replace the material.

5. The material itself and its surroundings may have factors that absorb UV light, causing the light energy to reach the colloid and attenuate. Green is the most absorbing light. At the same time, if you want to enhance the cohesion of the UVLED curing machine, you can use silver or aluminum foil to reflect and focus.

6. The influence of weather and environment, including high temperature, strong light, and the temperature of the south wind in spring, will lead to changes in the properties of UV glue. It is recommended to seal the glue and store it after normal use and use.

7. UV glue deteriorates, etc., it is recommended to replace the glue. A simple way to check whether the UV glue has deteriorated is as follows: first, to see if its color has changed; second, to see whether there are abnormal particles, crystallization, agglomeration or delamination in the UV glue; third, pour it down to see if it flows evenly.
