High temperature resistant filter cartridge substrate filter material stiffening finishing method

Abstract

The present invention discloses a high temperature resistant filter cartridge substrate filter material stiffening finishing method, and the high temperature refers to the use temperature of a substrate filter material is 130 DEG C-280 DEG C; concrete steps are as follows: (1) methyl silicone resin G-070, hydrogen-containing silicone oil emulsion H-1 and water are mixed and stirred evenly in the mass ratio of 10%-30%:15%-45%:25%-75% to prepare a high-temperature resistant stiffening agent; (2) the filter cartridge substrate filter material is immersed in the high-temperature stiffening agent and rolled to dry by a roller, and pickup rate is controlled at 110 to 130%; (3) the rolled-dried filter cartridge substrate filter material is put into a drying oven at 210 DEG Cfor 10 to 15 minutes for cross-linking and curing. The methyl silicone resin and the hydrogen-containing silicone oil emulsion are used for cross-linking and curing at 210 DEG C, a cured material is not softened at 280 DEG C, and can remain stable toughness, hardness and shape, the processed filter material can maintain a sufficient stiffness at high temperature, and the method is simple and practical and easy to promote.

Description

technical field [0001] The invention relates to a finishing method of a filter material, in particular to a method for stiffening and finishing a filter material of a base material of a high-temperature-resistant filter cartridge. Background technique [0002] Cartridge dust collector has been widely used in dust purification in many industries due to its small equipment volume and large filtration area. The current finishing methods for the filter material of the filter cartridge base material mostly use the spunbonding method, the melt blown method to obtain the filter material with stiffness, or use glue to stiffen the filter material, but the filter cartridges made by these preparation methods have poor air permeability. , Filtration resistance and other issues. At the same time, the existing domestic low-temperature filter cartridge products such as polyester filter cartridges have matured, but because most polymer materials will soften at high temperatures, high-tempe...

Problems solved by technology

Such products have a stiffening effect at room temperature, but will soften at high temperatures so that the filter cartridges will lose their stiffness at the use temperature, and the filter cartridges will be deformed due to filtration-injection during use, which limits Application of filter cartridges in high temperature field
