Filtration media, media pack assemblies, and methods

The technology disclosed herein relates to a filter media having a fiber matrix and a binder distributed throughout the fiber matrix. Conductive particles are impregnated in the binder matrix and a flame retardant distributed throughout the fiber matrix and the binder matrix. The filter media can be incorporated into various types of media pack assemblies for air filtration including coiled media,pleated media, and stacked filter media. A method is also disclosed where conductive particles are distributed in a binder and a fiber matrix is impregnated with the binder. A solution containing atleast 5% flame retardant solids is formed and the fiber matrix is saturated in the solution. The saturated, impregnated fiber matrix is dried and cured. 在此披露的技术涉及一种过滤介质，所述过滤介质具有纤维基体和分布遍及所述纤维基体的粘合剂。导电颗粒浸渍在所述粘合剂基体中并且阻燃剂分布遍及所述纤维基体和所述粘合剂基体。所述过滤介质可以结合到用于过滤空气的各种类型介质包组件中，所述介质包组件包括卷绕介质、褶皱介质、和层叠过滤介质。还披露了一种方法，其中，导电颗粒分布在粘合剂中并且纤维基体浸渍以所述粘合剂。形成含有至少5％阻燃剂固体的溶液并且在所述溶液中使所述纤维基体饱和。干燥并固化所述饱和的浸渍纤维基体。
