Why does PUR hot melt adhesive appear stringing and bubbles?
Nov 08 , 2023
Cohesive strength of PUR hot melt adhesive machine The law of influence between the cohesive strength of PUR hot melt adhesive colloid and wire drawing is: if the cohesive strength is large, the wire drawing phenomenon will be obvious; on the contrary, if the cohesive strength is small, the wire drawing phenomenon will not occur. PUR hot melt adhesive curing time The curing time of PUR hot melt ad...

Entering winter, you need to know about these operations of hot melt adhesive machines
Nov 20 , 2023
1.As the temperature gradually drops in winter, some customers have experienced poor adhesion, brittle hot melt adhesive, and degumming when using hot melt adhesive for production. What is the reason? Hot melt adhesive is sensitive to ambient temperature. Due to the cold temperatures in winter, the hot melt adhesive bonding process is cold, resulting in rapid solidification and hardening. Some glu...

Why hot melt adhesive cools before bonding
Mar 26 , 2024
The hot melt adhesive cools before bonding. The reasons and solutions are as follows: (1) The use temperature of hot melt adhesive is low → increase the use temperature; (2) The opening distance is too long → reduce the opening distance; (3) The conveyor belt speed is too slow → increase the conveyor belt speed; (4) The amount of glue applied is not enough → increase the amount of glue applied; (5...

How to solve glue gun leakage
Jun 20 , 2024
1. Glue leakage at the Hot melt gluing nozzle If glue leaks from the nozzle during glue spraying, the possible reasons are as follows: a. The temperature of the glue gun is not enough. The temperature of the hot melt glue gun should be increased appropriately. b. If the pressure or flow rate of the air jet is too small, glue will drip from the nozzle. Increase the pressure of the air blowing...
