Abstract

The invention discloses a high-temperature-resistant and low-expansion adhesive sealant for a filter cartridge. The adhesive sealant is prepared from the following components of a basic polymer, powder, a cross-linking agent, a coupling agent and a catalyst. The invention provides the high-temperature-resistant and low-expansion adhesive sealant for the filter cartridge according to characteristics of the making mode, the service environment, the working condition and the like of the filter cartridge; the made adhesive sealant has the features of being resistant to high temperature, resisting heat shock, being low in expansion, being resistant to acid and alkali, resisting aging and being long in service life, and is applicable to the filter cartridge which is used in severe and complicated working conditions of a coal-fired power plant, garbage incineration and the like for a long term.

Description

technical field [0001] The invention relates to an adhesive sealant, in particular to a high-temperature-resistant and low-expansion adhesive sealant for a filter cartridge. Background technique [0002] Cartridge dust collectors appeared in Japan and some European and American countries as early as the 1970s. They have the advantages of small size, high efficiency, low investment, and easy maintenance. However, due to their small equipment capacity, it is difficult to combine them into large air volume equipment. The wind speed is low and the application range is narrow. It is only used in food, welding and other industries, so it has not been widely promoted for many years. In recent years, with the continuous development of new technologies and new materials, the structure and filter material of the dust collector have been improved, so that the filter cartridge dust collector can be used in industrial fields such as cement, steel, electric power, food, metallurgy, and ch...
