Working principle and operation of small epoxy vacuum defoaming machine:

The device uses air pressure differences to remove air bubbles from the product. For example, we use it in the resin adhesive industry.

Operation steps:

1. Put the colloid to be treated into the equipment, open the 1 valve to discharge the air, so that the pressure difference between the product placing chamber and the vacuum pump is formed.

2. Open the two valves of the vacuum pump and the product placement chamber to remove the gas in the product under the action of the pressure difference.

3. After we complete the exhaust process, open the pneumatic gate and take out the product. Make its surface dense! (With automatic defoaming vacuum equipment, this step can be omitted) Repeat the work!

Note: This product can also be used Note: LED industry electrical defoaming steps are much the same, after the completion of the product is smooth and glossy!

5, AB glue and UV glue mixing and defoaming. Defoaming in LED production.

6. Defoaming of glue filling products. The specific specifications of various adhesives, pastes and inks can be customized according to requirements.

Vacuum defoaming VS centrifugal defoaming:

Debubbling machine, debubbling function, vacuum debubbling and centrifugal debubbling principle

The role of the debubbling machine is to separate the air in the products that need to be debubbled, mainly used for glue, LED light-emitting diodes, digital tubes; LED epoxy resin, ink and other viscous substances to remove bubbles.

The glue used in some industries such as LED must be removed with a debubbling machine to remove the bubbles in the glue to avoid empty spots or other bad spots when dispensing. It is an essential equipment in the dispensing process.

The types of defoaming machines can be roughly divided into:

1. Vacuum defoaming,

2. Centrifugal defoaming

Vacuum defoaming: The oxygen in the product is removed by removing air (vacuuming) within the set time, and the defoaming effect can be accurately achieved.

Centrifugal deaeration (also known as agitated deaeration) uses rotation/revolution mixing to handle agitation, mixing, dispersion, and debubbling/venting simultaneously.

The advantages of vacuum defoaming machine: no pollution, short defoaming time, obvious effect, defoaming volume is greater than centrifugal defoaming, convenient and simple operation

Shenzhen QDI Technology Co., Ltd. was established in 2019, is a collection of production, sales, research and development as one of the technology company; The main products are planetary centrifugal vacuum stirring defoaming machine, magnetic material swing machine, scraping grinding machine, automatic screen plate micro testing light table, screen plate oven, anti-precipitation rolling machine, non-standard hardware products and non-standard machine equipment R & D and production, film storage equipment and accessories, etc. The company's products are widely used in the material industry, circuit board action, printing industry, photoelectric industry.
