 Overview
Porous membrane materials refer to layer-by-layer porous materials with specific physical and chemical properties, pore sizes, and pore size distributions obtained through specific processes. The average pore size can range from several nanometers to several tens of micrometers. Porous membrane materials can be used for screening, separation, distribution, and exchange of specified substances. Generally, porous membrane materials can be divided into inorganic and organic materials. Inorganic porous membrane materials are further divided into metal porous membrane materials (metal membrane) and ceramic porous membrane materials (ceramic membrane).
Metal porous membrane materials are often used in situations with large changes in working conditions and unstable process parameters due to their inherent reliability. However, the problem of larger average pore size restricts their application in high-precision filtration and separation. Ceramic porous membrane materials are often used in more stable working conditions and process parameters, and they can be prepared with membrane layers of 20 nanometers or even higher precision. This characteristic makes them widely used in high-precision separation fields.
Sintered membrane porous components have high mechanical strength and can be used at higher pressures. This allows for an increase in permeation rate by increasing the membrane pressure difference in membrane separation. In filtration processes, sintered membrane porous components have high filtration accuracy, low pressure difference, and are easy to clean, offering high application value.
Our membrane material laboratory has successfully developed ceramic-metal composite porous membrane materials to address the problem of low precision in metal porous membrane layers. These materials can meet the demands of high-precision separation fields, especially for unstable working conditions and unstable processes or for applications with high reliability requirements. Additionally, the laboratory has developed a variety of porous membrane materials such as SiC, mullite, Al2O3, SiAlON, ZrO2, TiO2, stainless steel, molybdenum, nickel, and iron aluminum to meet users' demands for reduced operating costs in stable working conditions and processes.
