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...

What should we do if the hot melt glue machine makes noise?
Aug 13 , 2021
The hot melt glue machine has aerodynamic noise: it is caused by the vibration of the gas body, such as the noise caused by the exhaust fan, the refrigeration compressor, the automobile engine, the jet plane and the rocket bomb. Magnetically induced noise: Noise caused by magnetically induced vibrations, such as motors, generator sets, and transformers. Reflective noise: noise caused by solid-stat...

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...

The reason why the hot melt glue machine does not heat up
Aug 16 , 2021
With the change of the times, mechanization is getting closer and closer to life. Most of the products used in life need to be bonded to form objects. The glue required for traditional bonding has been gradually eliminated with the strengthening of environmental protection awareness, and the environmental friendly hot melt adhesive has gradually appeared in the public view, Among them, the essenti...

The method of cleaning nozzles
Aug 17 , 2021
The nozzle is an important part of the hot melt glue machine accessories. The glue comes out of the glue nozzle, but if it is used improperly, it is easy to cause blockage and reduce work efficiency. So when we stop using the hot melt glue machine, what should we do? How about cleaning nozzles? 1. Use a smokeless hot air gun to heat it, and then wipe it clean with a clean cloth. 2. The nozzle is i...

How to choose a good hot melt hose?
Aug 19 , 2021
From the analysis of the current sales, the glue machine hose has occupied most of the market, but how to distinguish the inferior hot melt glue hose? Let me share some small methods for everyone. 1. The insulating layer is easy to wear and leakage occurs 2. Glue leakage occurs when the insulating sleeve is broken 3. The rusty joints will also cause glue leakage 4. The pipe bursts due to uneven he...

Installation of Hose & Nozzle Assembly
Aug 20 , 2021
1.Fix the nozzle assembly horizontally or vertically in a proper place (assembly line,a desktop shelf,etc) with a Ф0.5” steel stick. Keep the nozzle facing the area to be sprayed or injected or coated. Note:When removing or installing nozzle assembly,extreme care should be given to protect the nozzle. 2.Connect one side of the hose to the outlets of manifold,and tighten the connection part with a ...
