What is the reason for the formation of bubbles after the curing of the glue machine- Hongzhan Automation

In recent years, industrial automation has developed rapidly. Many enterprises use glue dispensers instead of manual labor. The use of glue dispensers can save labor and improve production efficiency. However, in the process of using the glue dispenser, we inevitably encounter various problems. If we do not carry out professional processing, our gluing efficiency will be greatly affected. The following will explain to you the reasons for the formation of bubbles after the curing of the glue dispenser!

Factor 1: During the filling process of the glue machine, during product filling and the entire curing process, the air is not completely emptied and enters, resulting in a lot of air entering!

Phenomenon: The glue pouring machine will produce very small bubbles after the glue is solidified.

After mixing the main agent and curing agent together, the dual liquid glue filling machine will extract the air inside the glue, and then turn on the heating system of the glue filling machine to preheat the products that need to be filled. Then, we can choose to perform the glue filling and curing work in a humid temperature 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 pouring machine produces large bubbles after the glue is solidified

The main agent has been used many times. During the mixing process of the glue dispenser, water may be mixed, which may also be due to the packaging lid not being tightly closed.

The product filled by the glue filling machine has too much moisture. It is recommended to preheat the product before gluing.

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

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

In summary, these are the main reasons for the formation of a large number of bubbles after the curing of the glue machine. We need to be careful to avoid similar situations when pouring glue every day.
