Stainless steel sintered filter is a porous filter element made by sintering a multi-layer stainless steel braided mesh and a punched plate frame (perforated plate is not necessarily used as the frame) to make them firmly combined. This filter element not only maintains the punching properties The strength of the orifice plate skeleton has good thermal conductivity, electrical conductivity, plastic toughness, weldability and easy processing. At the same time, it inherits the filtration accuracy and corrosion resistance of the metal braided mesh, making it an ideal filter element.
The sintering process of the stainless steel sintered filter is to stack the skeleton layer, protective mesh and main filter in order in a vacuum sintering furnace. Under the action of high temperature and high vacuum environment and external pressure, the surface oxygen film is broken. Achieve effective contact and full diffusion of the metal surfaces of each layer, forming a reliable diffusion connection between each layer.
The main principle of sintering processing is vacuum diffusion welding. However, unlike ordinary diffusion welding, due to the thin diameter of the metal braided mesh and the dense and complex weaving method, the surface oxide film is difficult to remove, which is not conducive to diffusion, so it is broken and evaporated. The oxide film on the surface of the orifice plate and wire mesh, the sintering temperature of the sintering process is higher than that of general vacuum diffusion welding.
Because of its advantages of good anti-cleaning effect, excellent corrosion resistance, excellent comprehensive mechanical properties, easy processing, good heat resistance and small pressure drop loss, it is widely used in high-tech and emerging technologies such as environment, energy, chemical industry and biology. Industrial field.
