Hot-melt glue sticks used in winter often
have the phenomenon that it is difficult to glue and even the glue strips are
brittle and break. Especially some high-speed adhesives and high-strength glue
sticks are more likely to be glued. This is because hot-melt adhesive rods are
greatly affected by the ambient temperature. For example, the essence of hot-melt
adhesive curing is the heat dissipation process, while the winter environment
temperature is lower and the heat dissipation speed is faster, which invisibly
accelerates the curing speed. Glue sticks that can be used well in summer may
not be effective in winter, and vice versa. The reason for the unqualified glue
stick is often insufficient heating. The measures that can be taken to find
this situation are: replace the winter hot melt glue stick, or equip multiple
glue guns in one station for alternate use.
In addition to the above, there are also
hot-melt glue sticks that are universal in all seasons. The so-called glue
sticks that are universal in all seasons actually balance the temperature
difference between winter and summer. The moderate effect can be achieved by
adjusting the formula. It is more suitable for general applications, some
occasions with special applications are not necessarily suitable, such as fast,
high cohesion, low cohesion, slow speed, etc., it is not suitable for the use
of four-season general-purpose adhesive strips of.
