During the preparation and application of adhesives, bubbles may impair their performance and quality. To solve this problem, vacuum defoaming machines are developed. Combining centrifugal force and vacuum pump, the machine quickly removes bubbles inside adhesives so as to improve product quality and reliability. This article elaborates on how vacuum defoaming machines remove bubbles from adhesives by centrifugal force and vacuum pump.

Working Principle of Vacuum Defoaming Machine The machine completes adhesive defoaming through the following steps:

1. Preparation: Place adhesive samples to be defoamed into the container of vacuum defoaming machine and ensure good sealing of the container.

2. Centrifugal Operation: Start the centrifugal function of the machine. The adhesive samples inside the container generate centrifugal force under high-speed rotation.

3. Bubble Separation: During centrifugation, bubbles get separated due to low density. Larger bubbles move upward to the liquid surface while tiny bubbles are pushed toward the liquid bottom.

4. Vacuum Extraction: The vacuum pump starts to extract air inside the container and gradually build a vacuum environment. Under vacuum, bubbles separate from adhesives and float upward more easily.

5. Bubble Discharge: As vacuum extraction proceeds, bubbles float to the liquid surface and are drawn out by the vacuum pump. Meanwhile, the exhaust system discharges bubbles out of the container.

6. Defoaming Completion: After a period of centrifugation and vacuum extraction, bubbles inside adhesives are thoroughly eliminated. Stop the machine after finishing defoaming.

Application of Vacuum Defoaming Machine for Adhesive Defoaming Vacuum defoaming machines are widely used in adhesive industry. Main application fields are listed below:

Industrial Adhesive Production

Vacuum defoaming machines are used to remove bubbles during industrial adhesive manufacturing. With the combined effect of centrifugal force and vacuum pump, bubbles can be efficiently separated from adhesives. It improves adhesive bonding strength and stability, and guarantees consistent product quality.

Automotive Manufacturing

Adhesives are widely used for assembly and bonding in automobile production. Bubbles inside adhesives may lead to weak bonding or voids, which threaten the quality and safety of auto parts. Vacuum defoaming machines effectively eliminate bubbles and enhance bonding reliability and durability.

Medical Device Manufacturing

Adhesives are commonly used for connection and encapsulation in medical device production. Bubbles may damage sealing performance and functionality of devices. Centrifugal force and vacuum extraction of vacuum defoaming machines efficiently remove bubbles and improve the quality and reliability of medical devices.

Art & Craftwork Production

Adhesives are used for bonding and coating in artwork and craft making. Bubbles will ruin the appearance and texture of works. Vacuum defoaming machines eliminate bubbles to maintain the integrity and aesthetics of finished artworks.

Vacuum defoaming machines efficiently remove bubbles from adhesives with centrifugal force and vacuum pumps to boost product quality and reliability. It plays a vital role in industrial adhesive production, automotive manufacturing, medical device manufacturing, artwork and craft production. By removing bubbles, vacuum defoaming machines secure bonding strength, stability and reliability of adhesives, delivering high-quality products and solutions for various industries. With further technological development, vacuum defoaming machines will keep serving adhesive-related sectors and drive innovation and progress of relevant industries.
