In recent years, industrial automation has developed rapidly, and many enterprises are using glue filling machines instead of manual labor. The use of glue filling machines can save labor and improve production efficiency! But in the process of using the glue filling machine, we inevitably encounter various problems. If we do not handle them professionally, it will greatly affect our glue filling efficiency. Below, the technical personnel of Xinluyuan Electronic Equipment will explain the reasons for the bubbles generated after the glue filling machine solidifies!

The formation of bubbles after the solidification of the glue machine is related to these factors.

Factor 1: During the glue filling process of the glue filling machine, air enters during the mixing of the glue. During the injection of the product and the entire curing process, the air is not completely evacuated, and a lot of air enters!

Phenomenon: The glue filling machine produces very small bubbles after curing the glue.

After mixing the main agent and curing agent together, we can use a dual liquid glue filling machine to extract the air inside the glue. Then, we can turn on the heating system of the glue filling machine to preheat the product to be sealed. We can choose to perform the glue filling and curing work in a relatively humid environment, which can effectively ensure the generation of bubbles after the glue filling and curing of the glue filling machine!

Factor 2: The reaction between moisture and curing agent produces gas.

Phenomenon: The glue filling machine produces large bubbles after curing the glue.

1. The main agent has been used many times, and moisture is mixed in during each mixing process of the glue filling machine. It is also possible that the packaging lid is not tightly closed.

2. The sealing product of the glue filling machine contains too much moisture. It is recommended to preheat the product before filling.

3. The surface of the mixture of main agent and curing agent reacts with the moisture in the surrounding air. We choose to cure it in a dry environment or in a high-temperature oven.

4. The mixture of liquid main agent and curing agent may have come into contact with other chemicals (such as solvents, release agents, varnishes, adhesives, etc.) before curing.

In summary, the main reasons for the large amount of glue produced by the glue filling machine after curing are roughly these factors. We need to pay attention to avoiding similar situations when filling glue in our daily lives.
