Product Description
A basalt fiber needle punched filter felt with high temperature resistance, anti-static properties, and high fracture strength, and its manufacturing process. The technical solution is a basalt fiber needle punched filter felt, which is made by needle punching the basalt fiber layers on the base fabric and the upper and lower layers of the base fabric. The base fabric is made from basalt fiber yarn as the raw material, and the basalt fiber layers are made by mechanical mesh forming process. The production process of basalt fiber needle punched filter felt includes the steps of mechanically forming a mesh to make a basalt fiber layer; Make a base fabric; Lay a layer of basalt fiber fibers on top and bottom of the base fabric, and make semi-finished basalt fiber needle punched filter felt by needle punching; Basalt fiber needle punched filter felt is made by dipping lotion and stretching and setting furnace.
