Vacuum pressure impregnation equipment, vacuum impregnation paint setting is to place the workpiece to be impregnated in a closed pressure-resistant container, evacuate the air, then inject the impregnating liquid into it, and apply the necessary pressure to make the impregnating liquid completely penetrate the gaps of the workpiece, finally achieving the impregnation goal. Vacuum pressure impregnation is primarily suitable for high-voltage (traction, explosion-proof) electromechanical equipment, practical transformers, discharge capacitors, discharge cables and other electrical appliances and electrical materials to supplement insulation. It is a necessary process action. This setting is also suitable for the process management of impregnating refractory bricks such as magnesia-carbon bricks and sliding plate bricks with asphalt.
The role of vacuum impregnation in powdered metals goes far beyond sealing pores. This process also reduces corrosion, enhances machinability and improves surface finish.
For metal sintered bodies and ceramic sintered bodies manufactured by powder metallurgy, they are themselves porous bodies. To enhance their mechanical properties, it is necessary to eliminate and reduce the pore defects inside them. The purpose of researching and developing impregnation technology lies precisely here.
Vacuum pressure impregnation technology is also applied in the manufacture of aluminum alloy composite materials. Aluminum alloy composite materials used for automotive engine pistons and other components must be light in weight and resistant to high temperatures.
Such components were originally produced by high-pressure casting and powder metallurgy, but these two methods are difficult to manufacture large and complex-shaped parts.
By using vacuum pressure impregnation technology, metal fibers can be used as reinforcing materials to produce metal composite materials, and the low-pressure impregnation method can be employed to manufacture large and complex-shaped metal composite material components.
