CICS Related Issues of UV Glue Curing Oxygen Obstruction

Now when we do glue testing for customers, we will encounter the use of UVLED devices to irradiate and solidively, and it will be a bit sticky to touch the surface of the glue with our hands. In the inside of cutting and curing glue, we can see that the glue is completely solidified after the glue is shot with the UVLED light. Why do you have such an imagination? This has extended an important problem in the UVLED curing industry. UV glue is the problem of oxygen resistance when curing up with UVLED device. Oxygen closure is a common problem in the reaction of optical curing. In the UVLED optical reaction, the free radicals generated by the cracked light cause of the light cause will be captured by oxygen to form peroxic free radicals. The problem. The method of overcoming oxygen blocking can be divided into two types: chemical and physical methods. The method of inert gas used in physical methods to isolate oxygen is a very effective method. The commonly used inert gases are usually nitrogen, or sorbe. The cost of nitrogen and gaseous gas is relatively high, and the other inert gas that can be used is carbon dioxide. The use of carbon dioxide has some advantages that other gases do not have: First, carbon dioxide is easy to obtain, and the cost is low. Secondly, because carbon dioxide is heavier than air, it is easy to maintain in the container, so that there will be less loss.
