Due to UV glue photoinitiator sensitivity, we need to pay attention to the effect of light on glue in the production and use of UV glue, so as not to affect the performance of UV glue because of improper light.
First pay attention to the use of workshop or equipment lighting.
Ordinary workshop fluorescent lamp contains part of the visible light can stimulate UV glue curing, resulting in UV glue polymerization at the dispensing end or line, as far as possible the workshop or equipment in the fluorescent lamp is transformed into yellow light.
Secondly, UV glue needle problem, need to pay attention to the use of ultraviolet amber needle, or black needle. The black needle completely blocks light and provides excellent protection against UV glue.
The dispensing needle should also pay attention to. The long-term dispensing operation may also cause the UV glue in the needle will start to gel, so the dispensing time is long and the needle needs to be replaced.
