What is the reason for the insufficient amount of glue in the pump of the hot melt glue sprayer?
Aug 11 , 2021
The hot melt glue machine can work 24 hours a day, but what is its working principle? In fact, it is very simple, mainly by heating the hot-melt adhesive, and transporting the liquid hot-melt adhesive through power. The pump of the hot melt glue machine is the main power and the center of the operation of the hot melt glue machine. Sometimes when working, there will be insufficient pumps. This sit...

Precautions and treatment methods for surface hot melt adhesive bonding
Aug 11 , 2021
The key points of hot melt adhesive bonding knowledge and some basic processing methods. To activate the surface to be adhered, through chemical or physical methods, some polar groups are introduced into the surface layer, so that the low-energy surface becomes the high-energy surface, the inert surface becomes the active surface, and the difficult-to-stick surface becomes the easy-adhesive surfac...

The reason why the sealing machine is not strong
Aug 14 , 2021
1. Material selection of the box: The selection error mainly refers to the imperfect matching of the hot melt adhesive or the type of boxes that need to be bonded, and it is difficult to meet the process requirements of the material itself. 2. The temperature during compounding does not meet the requirements: The compounding temperature does not reach the melting point of the adhesive film or omen...

Storage method of hot melt pellets
Aug 16 , 2021
Storage method of hot melt pellets: Precautions : 1. Sealed and stored. Hot-melt rubber particles will absorb moisture when exposed to the air. It is impossible to judge whether it absorbs water due to its appearance. The water-containing rubber particles tend to foam when they are melted, and reduce the bonding strength. Therefore, seal it to prevent moisture after application. 2. Hot-melt rubber...
