Filtering and environmental protection
There are many types of industrial filter materials, which can be divided into flexible filter materials (such as woven, non-woven materials, and organic membranes), rigid filter materials (such as sintered metal fiber felt, ceramic membranes, etc.), and loose filter materials (such as activated carbon, diatomaceous earth, etc.) according to their structure. Membrane material is currently a new type of material in filtration materials, which has selective filtration and separation functions. The difference between membrane filtration separation and traditional filtration is that the accuracy of membrane materials is often at the micrometer level or below. When there is a certain driving force on both sides of the membrane (such as pressure difference, concentration difference, potential difference, etc.), the raw material side components selectively penetrate the membrane, thereby achieving filtration, separation, purification, concentration and other effects.
