Many friends are curious, some uv Cured glue quilt uv The curing light cures very quickly, but some have poor curing effects, and some even don't cure at all. What's going on? Yongcheng will explain it now uv What are the glue curing conditions and how to choose the right one?uv Glue curing light?
uv Glue is actually a kind of photosensitive glue. It is a type of adhesive that must be cured by ultraviolet light. It has a wide range of uses. It can be used not only as glue, but also as paint, coating, ink and other glue. uv The curing principle of glue is because uv The photoinitiator (photosensitizer) in the glue absorbs ultraviolet light under ultraviolet irradiation and generates active free radicals or cations, which triggers monomer polymerization and cross-linking chemical reactions, causing the adhesive to solidify within seconds.
actually uv There are many types of glue. You can read the instructions for this. If there is a specific band marked, it is usually in 365nm-405nm within, then you can use the specified band uv led The curing lamp performs irradiation and curing, which is why all uv Glue, why can some be uvled There are some reasons why the curing lamp cannot cure. If the specified band is not marked, or multiple bands are marked, then it can be roughly judged that a mercury lamp is used for curing. uv Glue, because the mercury lamp emits a complete range of ultraviolet wavelengths, but because of its too many shortcomings, it is gradually being replaced by single-band glues. uvled Curing lamp replaced.
uv The curing conditions of the glue are to use those suitable for the band uv Just use the curing lamp for irradiation. Choose the appropriate one. uv Before using a glue curing lamp, you must first understand the glue used uv What type of glue is it? Is it a specific band or multiple bands? Want to make peace Just communicate with the manufacturer and make a selection based on the actual situation.
