Abstract

The invention relates to a glass fiber sintering filter cartridge and a preparing method thereof, and belongs to the technical field of glass fiber materials. In the method, a suction filter with a peripheral cylindrical metal net is mainly used, a wet filter cartridge is prepared through suction filtration, the prepared wet filter cartridge is subjected to hot-press sizing through a male die anda female die, and finally the glass fiber sintering filter cartridge is prepared through drying. The glass fiber sintering filter cartridge has the advantages of being stable in chemical performance,resistant to high temperature, resistant to corrosion, high in dust holding capacity, good in filtering performance and the like and is a filtering system widely used in the fields of industry, agriculture, national defense, scientific research and the like; the requirements for the glass fiber sintering filter cartridge are increased daily in all the fields; the preparing method of the filter cartridge is simple, easy to operate, low in cost and suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of glass fiber materials, and in particular relates to a glass fiber sintered filter cartridge and a preparation method thereof. Background technique [0002] The filter elements of filter products on the market are mainly polytetrafluoroethylene and activated carbon materials. Among them, the polytetrafluoroethylene filter element has strong acid and alkali resistance, and the strength and toughness of the filter element are very high. At the same time, the filter element can withstand high temperature up to 200 ℃ , has the laudatory title of "King of filter elements", but the dust holding capacity is a defect of this product. [0003] Activated carbon material filter elements are mainly divided into three types, one is sintered activated carbon, which is made by mixing activated carbon powder material and polymer hot-melt pore-forming material, pouring it into a special abrasive tool, and sintering it at a...
