With the development of the times and the strengthening of people's environmental awareness, more and more industries choose to use hot melt adhesive for spray production. During the production process, there may be an unsatisfactory bonding effect of hot melt adhesive. Today, the Oushida editor will analyze the reasons for this phenomenon for you:

1. The environment is humid. Hot melt adhesive becomes damp during storage, resulting in insufficient viscosity; The high humidity in the working environment makes the product materials damp, making it difficult for hot melt adhesive to penetrate and fuse with the materials, resulting in weak adhesion and difficulty in applying glue.

2. Check if the hot melt glue machine is working properly, ensuring that the main machine, hot melt hose, and glue gun are all working properly. Adjust the glue pressure of the hot melt glue machine and increase the spray glue pressure, which is also a common inspection method.

3. Carbides have appeared in the glue cylinder of the hot melt glue machine. When the content of carbides in the sprayed hot melt glue is too high, it will affect the adhesion of the hot melt glue and even block the rubber hose and glue gun. Therefore, the hot melt glue machine must be maintained and cleaned on time, and the hot melt glue must be replaced in a timely manner to maintain the working efficiency and glue application effect of the hot melt glue machine.

4. It is necessary to choose a suitable hot melt adhesive. Choose the right hot melt adhesive for different product materials and spraying processes. Different hot melt adhesives have different degrees of adhesion to materials. When purchasing hot melt adhesives, it is important to consult the adhesive manufacturer in detail to avoid unnecessary trouble.
