Embodiment Construction

[0017] The technical solutions in the present invention will be described in detail below in conjunction with specific embodiments, but are not limited thereto.

[0018] A glass fiber filter material, with glass fiber cloth as a carrier, a foam coating is arranged inside and outside the glass fiber cloth, there are bubble holes in the foam coating, and the diameter of the bubble holes is 2 ~17 microns. Because the pore size of the bubble hole is very small, more than 1000 times that of gaseous water molecules, and more than 200 times smaller than that of liquid water, water droplets and dust cannot pass through the foam coating, which can achieve effective waterproof and dust removal effects.

[0019] The specific production process is:

[0020] ——Production of glass fiber cloth: the glass fiber is drawn and warped, and then the cloth is woven by a loom, and then dewaxed and thermally cleaned to obtain a glass fiber cloth;

[0021] ——PTFE impregnation: put glass fiber cloth ...

Abstract

The invention discloses a glass fiber filter material. Glass fiber cloth is taken as a carrier. Foaming coatings are arranged inside and outside the glass fiber cloth. Bubble holes with a diameter of 2-17 micrometers are existed in the foaming coatings. The filter material is obtained after preparation of glass fiber, PTFE dipping and preparation and processing of PTFE coatings. The filter material has advantages of water resistance, good adhesive force, high temperature resistance, rub resistance and the like.

Description

technical field [0001] The invention relates to a filter material and a preparation method thereof, in particular to a glass fiber filter material and a preparation method thereof. Background technique [0002] At present, with the high emphasis on environmental protection in the continuous development of industrialization, the required environmental protection indicators are getting higher and higher, especially in terms of atmospheric dust and smoke emissions, my country has changed from the original emission standard of 100mg / m 3 , increased to 50mg / m 3 . This raises new issues for the improvement and development of the filter material industry: first, the improvement of the environmental protection performance of the filter material required to meet the standards; second, the expansion of the use of filter materials. Although my country's filter material industry has made rapid progress, it still cannot meet the continuous improvement of environmental protection indica...
