Which industries are vacuum stirring and defoaming machines used in? How did you get there?

Vacuum stirring and defoaming machine is mainly used in industries with high requirements for stirring and defoaming, such as LED lamps, LED epoxy resin, plastic toys, transformer glue filling, resin crafts, AB glue, silicone rubber, etc.

Principle:

The vacuum stirring and defoaming machine is a device that uses a vacuum pump to pump the air pressure inside the box to a vacuum, and uses the air pressure difference to pump out the air bubbles inside the product. The size of bubbles inside a liquid depends on the external pressure it receives. When the external pressure decreases, the bubble volume will increase; Just like blowing air into a balloon, which causes the balloon to expand when the external pressure is smaller than the internal pressure. Therefore, once the atmospheric pressure on the liquid surface is rapidly reduced (vacuumized), the volume of the bubbles inside the liquid increases rapidly, and the buoyancy naturally increases and quickly floats to the liquid surface. As a result, the bubbles accelerate to disappear, and the dissolved gas inside the liquid also decreases in solubility due to the decrease in the liquid surface pressure.
