Three reasons why UV glue cannot be curedread count [628] release time：2021-12-13 09:35:00

Not familiar with uv When using glue, many customers have encountered uv If the glue fails to cure, let’s briefly talk about it here uv Three reasons why glue won’t cure.

1.Curing band mismatch

The light curing band does not match, which is also the most encountered situation. uv Glue is generally irradiated with ultraviolet rays of a specified band, causing the photosensitizer to initiate monomer polymerization, cross-linking chemical reactions, and then solidify. usually use uv The band for glue curing is 365nm、385nm、395nm、405nm , if using and uv If the glue is irradiated with a curing lamp that does not match the glue, it will not dry.

2.uv There is a problem with the light source of the curing equipment. The curing equipment is aging or damaged, resulting in energy attenuation and insufficient light intensity. uv The need for glue leads to uv The glue cannot be cured or is incompletely cured. This can be detected by an electric energy meter. If a problem is found, the curing equipment needs to be replaced.

3.Incomplete lighting, average uv Glue needs to be cured by ultraviolet irradiation. If it is applied to a place that is not exposed to light or an object with poor light transmittance, it will cause uv The glue does not cure or is not completely cured.

now uv glue and uvled The technology of curing machines is becoming more and more mature and stable, and many companies have begun to use it. uv glue instead of traditional glue, Yongcheng Zai uvled With more than ten years of experience in R&D and production, it has been recognized by customers.
