Abstract

The invention discloses a water and oil repellent finishing method for a bag type dedusting material and relates to a material finishing method for high-temperature gas treatment of steel works, industrial furnaces, and industrial boilers. The finishing method comprises the following steps of: (1) preparing a finishing agent, namely weighing polytetrafluoroethylene (PTFE) emulsion, polymethylphenyl siloxane fluid emulsion, alcohol, Tween, glycerol, a hardening agent, resin HA, and adhesive and water in a mass ratio and placing in a container, stirring and mixing uniformly, and thus obtaining the finishing agent for later use; (2) padding the dedusting material by using the prepared finishing agent by a padding machine, wherein the pressure of a rotary drum of a compression roller during padding of the dedusting material is 0.5 to 0.7 MPa, and the speed of the rotary drum is 3.5 to 5.5 m / min; (3) allowing the padded dedusting material to pass through a drying oven, wherein the drying temperature is 140 to 190 DEG C, and the travel speed of the dedusting material in the drying oven is 3.5 to 5.5 m / min; and after the dedusting material is dried, winding the dried dedusting material on a fabric roller to finish the water and oil repellent finishing work of the bag type dedusting material.

Description

technical field [0001] The present invention relates to a water-repellent and oil-repellent finishing method for bag-type dedusting materials, which relates to a material finishing method for high-temperature gas treatment in steel mills, industrial furnaces, and industrial boilers, specifically, a kind of bag-type dedusting materials Water and oil repellent finishing method. Background technique [0002] In the field of filter materials, bag filter is a common cleaning method for online cleaning. In the working condition of the bag filter, the mixed gas of steam, oil gas and other acidic and alkaline gases is often encountered. This mixed gas often has strong acid and strong alkalinity, and the filter material that has not been treated with water and oil repellency will absorb The mixed gas will cause the material to be corroded and its strength will decrease; while the surface tension of the filter material treated with water and oil repellency increases, the mixed gas i...
