METHOD OF FORMING FILTER ELEMENTS

A method of forming a filter element is disclosed comprising introducing a mixture into a mold, the mixture comprising a plurality of susceptor particles and a plurality of polymeric binder particles. Eddy currents are induced in the susceptor particles by subjecting the mixture to a high-frequency electromagnetic field, the eddy currents being sufficient to elevate the temperature of the susceptor particles to cause adjacent polymeric binder particles to be heated to at least a softening point. The susceptor particles bind with the heated polymeric binder particles in the mold to form a coherent mass. The coherent mass is cooled to form the filter element. 本发明公开了种形成过滤元件的方法，该方法包括将混合物引入模具中，所述混合物包含多个感受器粒子和多个聚合物粘合剂粒子。通过使所述混合物经受高频电磁场而在所述感受器粒子中诱导涡电流，所述涡电流足以升高所述感受器粒子的温度以使得相邻的聚合物粘合剂粒子被加热至至少软化点。使所述感受器粒子与经加热的聚合物粘合剂粒子在模具中粘合以形成粘结块体。冷却所述粘结块体以形成过滤元件。
