What type of green silicon carbide is used for ceramic membranes?
Ceramic membranes can use 10,000 mesh green silicon carbide, and the peak value of 10,000 mesh green silicon carbide does not exceed 3um.
Ceramic membrane refers to an inorganic ceramic membrane, a non-precision ceramic membrane made of inorganic ceramic materials through a special process. Ceramic membranes are divided into two types: tubular ceramic membranes and flat ceramic membranes. The wall of the tubular ceramic membrane is densely covered with micropores. Under pressure, the raw material liquid flows in the membrane tube or on the membrane. Small molecular substances (or liquids) penetrate the membrane, and large molecular substances (or solids) are intercepted by the membrane, thereby achieving separation and The surface of the flat ceramic membrane is densely covered with micropores for the purposes of concentration, filtration and environmental protection. Within a certain membrane pore size range, the permeability will be different depending on the diameter of the molecules of the permeable material. The countless pressure differences across the membrane are the driving force, and the membrane is the filter medium. , under a certain pressure, when the feed liquid flows through the membrane surface, only water, inorganic salts, and small molecular substances are allowed to pass through the membrane, while large molecular substances such as suspended solids, glue, and preservatives in the water are prevented from passing through.
