COMPOUND FILTER MEDIA INCLUDING GRAPHENE FILTER MEDIA

摘要

The present invention relates to compound filter media including graphene filter media, and more specifically, to compound filter media which is obtained by forming a graphene filter media layer using a graphene solution, and combining a melt-blown media layer with electric charge on the upper side of the graphene filter media layer using polypropylene or polyethylene. Additionally, the present invention relates to a manufacturing method of the compound filter media which has high removal efficiency of contaminants while extending the lifetime of a filter by being able to be driven by low differential pressure.;COPYRIGHT KIPO 2018
