In the preparation and application process of adhesive, the presence of bubbles may affect its performance and quality. In order to solve this problem, vacuum defoaming machines have emerged. The vacuum defoaming machine utilizes centrifugal force and vacuum pump to quickly remove bubbles from the adhesive, thereby improving the quality and reliability of the product. This article will provide a detailed analysis of how a vacuum defoaming machine utilizes centrifugal force and a vacuum pump for glue defoaming.

The working principle of a vacuum defoaming machine is to achieve the defoaming of glue through the following steps:

1. Preparation: Place the adhesive sample to be defoaming in the container of the vacuum defoaming machine and ensure that the container is well sealed.

2. Centrifugal operation: The vacuum defoaming machine starts the centrifugal operation function, and the adhesive sample in the container begins to generate centrifugal force while rotating at high speed.

3. Bubble separation: During centrifugal operation, due to the lightweight characteristics of bubbles, they are separated by centrifugal force. Larger bubbles will move towards the upper part of the liquid, while smaller bubbles will be pushed towards the bottom of the liquid.

4. Vacuum extraction: The vacuum pump of the vacuum defoaming machine starts working, extracting air from the container and gradually establishing a vacuum environment. In a vacuum environment, bubbles are more likely to separate from the glue and float upwards.

5. Bubble discharge: As vacuum extraction proceeds, bubbles gradually rise to the surface of the liquid and are pumped out by a vacuum pump. At the same time, the exhaust system of the vacuum defoaming machine discharges bubbles from the container.

6. Defoaming completion: After a period of centrifugal operation and vacuum extraction, the bubbles in the glue will be completely removed, achieving a defoaming effect. At this point, the operation of the vacuum defoaming machine can be stopped.

The application of vacuum defoaming machine in glue defoaming has a wide range of applications in the glue industry. The following are several main application areas:

Industrial adhesive production

In the preparation process of industrial adhesive, a vacuum defoaming machine is used to remove bubbles from the adhesive. Through the combined action of centrifugal force and vacuum pump, the vacuum defoaming machine can efficiently separate bubbles from the glue. This can improve the adhesion and stability of the adhesive, ensuring consistency in product quality.

Automobile manufacturing

In the process of automobile manufacturing, it is necessary to use glue for various assembly and bonding work. However, bubbles in the adhesive may cause weak adhesion or create gaps, thereby affecting the quality and safety of automotive components. The application of vacuum defoaming machine can effectively remove bubbles in adhesive, improve the reliability and durability of bonding.

Medical device manufacturing

In the manufacturing process of medical devices, adhesives are widely used for connection and packaging. However, bubbles in the glue may affect the sealing and functionality of the instrument. By using the centrifugal force and vacuum extraction of the vacuum defoaming machine, bubbles in the glue can be effectively removed, improving the quality and reliability of medical devices.

Art and Craft Production

In the production process of artworks and handicrafts, glue is commonly used for bonding and coating. However, the presence of bubbles may damage the appearance and texture of the work. The application of vacuum defoaming machine can eliminate bubbles in glue, maintaining the integrity and aesthetics of the work.

The vacuum defoaming machine utilizes centrifugal force and vacuum pump to efficiently remove bubbles from the adhesive, improving product quality and reliability. It plays an important role in industrial adhesive production, automobile manufacturing, medical device manufacturing, as well as art and handicraft production. By removing bubbles, the vacuum defoaming machine ensures the adhesion, stability, and reliability of the adhesive, providing high-quality products and solutions for various industries. With the further development of technology, vacuum defoaming machines will continue to play an important role in the field of glue and promote innovation and progress in related industries.
