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 doesn't the hose or glue gun of the hot melt glue machine heat up?
Dec 18 , 2023
Hot melt glue machines, hot melt glue guns, and hot melt hoses all have heating functions to prevent the hot melt glue from cooling during the circulation process, thereby affecting the product bonding effect. What to do if the hot melt glue tube or hot melt glue gun does not heat up? Today we will briefly introduce you to several troubleshooting methods. 1. The heating wire (rod) is damaged: firs...

Is hot melt adhesive on diapers harmful?
Mar 21 , 2024
Why do diapers use hot melt adhesive? The production process of diapers is a relatively complex combination process, which is composed of surface non-woven fabrics, water-absorbent cores, PE composite bottom films, magic buckles and front waist stickers, anti-side leakage non-woven fabrics, elastic bands and many other materials. The combination of the above materials is bonded through hot melt ad...

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...

Reasons why the carton sealing effect is not ideal
Jun 04 , 2024
Using hot melt glue to seal cartons is already very mature in the industry, but sometimes the glued box will open as soon as you pinch it. What is going on? First of all, it is necessary to determine whether the material used to make the box is the same as before, and whether the surface has been treated in any way, resulting in poor hot melt adhesive. In this case, the main reason is that t...

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...
