Due to its characteristics, the carbon
deposition problem of hot melt adhesives is inevitable, but the results are
different depending on the type of glue and the flow conditions during use. For
example, when the glue is not flowing, the heating device should not be turned
on for a long time, because the hot melt glue channel at the glue gun and
nozzle is small and the capacity is only a few grams. If the glue is heated for
a long time without flowing, it will take a few hours. Carbon deposits will be
formed and the nozzle channel will be blocked.
Therefore, sometimes in order to save the
time to reheat the glue after work, it is a wrong way to use the practice of
not shutting down after get off work, and it is easy to cause damage to the
glue machine due to carbon deposits.
