[0002] Vacuum defoaming machine is a kind of special equipment using vacuum negative pressure principle to remove the bubbles in material. The working principle of vacuum defoaming machine is based on the pressure difference effect of physics. When the gas in a certain space is extracted to form a low pressure or vacuum state, the gas molecules in the space will quickly diffuse to the high pressure area outside, at the same time, the tiny bubbles in liquid or solid are driven to move to the surface and release. In the vacuum defoaming machine, the material to be processed is placed in a sealed vacuum chamber, and with the start of vacuum pump, the gas in the chamber is quickly extracted to form a vacuum environment. In this process, the bubbles inside the material begin to expand and move to the surface due to the action of external pressure difference, and finally break and release to the vacuum on the material surface. At the same time, the vacuum defoaming machine is usually equipped with a heating system to accelerate the expansion and release process of the bubbles, further improving the defoaming efficiency. In addition, some vacuum defoaming machines are also equipped with stirring or vibration devices to promote the faster discharge of bubbles in the material.
