There are two reasons, the influence of the temperature of a machine, the temperature is too low, the thin consistency of the glue itself increases, and the phenomenon of wire drawing is produced. It is very important to increase the heating temperature of hot melt glue, the curing time of two hot melt glue, and the curing time of hot melt glue to produce wire drawing phenomenon. Generally speaking, the shorter the curing time of hot melt glue, the lower the probability of wire drawing, because

Caused by the long curing time, at this time, there are residues on the surface of the adhesive, but the adhesive still pops open, because it is not completely dry, the bonding process has ended, and the bonding force between the hot melt adhesive will be very small, and the glue is separated from the glue, resulting in failure to stick. It is recommended to replace the hot melt adhesive with a short curing time or increase the pressing time so that the hot melt adhesive is completely cured befo

WZX hot melt adhesive is a solid binder based on ethylene-vinyl acetate copolymer (EVA) and a combination of tackifier and other ingredients. Hot melt adhesives also have a shelf life. Long-term contact with air can cause the hot melt adhesive to slowly oxidize. If it is improperly stored, it will cause the glue to become yellow, and the EVA hot melt adhesive itself is not waterproof. It will be placed in a humid place for a long time. If it is too hot or too cold, it will have a certain infl
