A vacuum defoamer is a device used to remove bubbles from liquid or solid materials, eliminating bubbles through a vacuum environment to improve product quality and stability. By reducing environmental pressure to cause bubbles in the liquid to expand and escape, it is suitable for defoaming high viscosity materials such as silicone and epoxy resins, while accelerating bubble separation through stirring or centrifugation.
The core principle of vacuum defoamer is based on the pressure difference effect:
Vacuum environment: By pumping air with a vacuum pump, the pressure inside the box is reduced, causing bubbles in the liquid or solid to expand at low pressure and increase buoyancy, thereby rising to the surface and breaking.
Auxiliary function: Some devices are equipped with stirring or vibration devices to accelerate the accumulation and escape of bubbles; The heating system can accelerate the expansion and release of bubbles, improving the efficiency of defoaming.
operating procedure
Equipment preparation: Check the status of components such as power supply, vacuum pump, heater, etc. to ensure that the interior of the equipment is clean.
Parameter setting: Adjust parameters such as temperature and vacuum degree according to material properties.
Feeding and defoaming: Add the material to be processed into the defoaming chamber, start the defoaming program, and observe the changes in the material.
Discharge and cleaning: After defoaming is completed, remove the material and clean the inside of the equipment.
The operation of the vacuum defoamer is simple. Simply place the colloid to be processed into the equipment, set the corresponding parameters, and start the equipment to automatically complete the defoaming process. Operators do not need to possess professional skills and knowledge, and can quickly get started using it.
Vacuum defoamers are usually equipped with automated control systems that can accurately control various parameters during the defoaming process, such as vacuum degree, temperature, stirring speed, etc., to improve the defoaming effect and efficiency.
The vacuum defoamer is made of good materials and components, with a reasonable structure, safety and reliability. It has multiple safety protection functions, such as overload protection, leakage protection, etc., which can ensure the safety of operators and the service life of equipment.
The vacuum defoamer can be reused, which not only saves costs but also meets environmental protection requirements. After completing a defoaming process, the colloid can be removed and the next colloid that needs to be defoamed can be placed in the equipment for continued use.
