Structural characteristics
Phenolic resin filter elements are usually composed of phenolic resin as the framework and sintered with various fibers. This structure enables the filter element to possess both the precision and high dirt-holding capacity of the fiber-wound filter element and the stability of phenolic resin. In addition, some phenolic resin filter elements also feature a unique two-stage filtration structure, which further enhances filtration efficiency and service life
Manufacturing process
Phenolic resin fiber filter elements are formed by sintering the fibers with binders, curing agents and stabilizers at high temperatures. This process ensures a tapered structure, uniform micropore size and high porosity of the filter element, thereby enhancing its retention capacity and service life
Chemical industry: Due to its chemical stability, phenolic resin filter elements are often used in the chemical industry to filter some special chemicals or solvents.
In the electronics industry, phenolic resin filter elements can be used to filter process liquids such as electroplating solutions.
High-temperature liquid filtration: Due to its high-temperature resistance, phenolic resin filter elements are suitable for the filtration of high-temperature liquids, such as in the petrochemical industry and other fields.
Corrosive medium filtration: In some environments containing corrosive media, phenolic resin filter elements can demonstrate their corrosion resistance.
