Abstract

The invention discloses a preparation method of a flexible glass fiber honeycomb body. The method specifically comprises the following steps: (1) firstly immersing glass fiber mats into a forming liquid, then drying, and finally adding into a corrugating machine for forming to obtain corrugated glass fiber mats; (2) alternately overlapping the glass fiber mats and the corrugated glass fiber mats, then immersing the glass fiber mats and the corrugated glass fiber mats in a binder, and finally drying to obtain a glass fiber honeycomb body; and (3) cutting the glass fiber honeycomb body into glass fiber honeycomb body sheets along the pore channel direction, then heating, finally bending into any shape, and cooling and fixing to obtain the glass fiber honeycomb body. According to the method, the glass fiber honeycomb body is assembled by adopting the plastic binder, so that the honeycomb body is deformed by heating and shaped by cooling, can be repeated for multiple times, and has a flexible characteristic.

Description

technical field [0001] The invention relates to the technical field of environmental protection materials, and more specifically relates to a preparation method of a flexible glass fiber honeycomb body. Background technique [0002] With the improvement of air quality requirements, the number of control objects for pollutant components in the air is also increasing. For example, indoor air has expanded from fine particle control to odor control, industrial waste gas has expanded from single pollutant control to multi-pollutant coordinated control, and so on. [0003] Currently, researchers are studying how cartridge-type air purifiers can increase CO2 in existing cartridges. 2 Control module, some researchers are also studying how to realize the integration of dust removal and denitrification in industrial cartridge dust collectors. One of the key problems to be solved for the application of these studies is to develop a module that can be integrated with the filter cartri...
