Abstract
The invention relates to a high-temperature-resistant composite filter cloth comprising a base cloth and felt layers. The base cloth comprises glass fiber cloth. The felt layers are respectively arranged on the two sides of the base cloth. The felt layers comprise glass fiber, basalt fiber, ceramic fiber, or a mixture of more than two selected from the above three. The base cloth and the felt layers are compositely connected into an integral structure through puncturing. Polytetrafluoroethylene wear-resistant coatings are arranged on the surfaces of the felt layers. The thickness of the coatings is 0.18-0.2mm. Compared with prior arts, the composite filter cloth is prepared with glass fiber, basalt fiber and ceramic fiber; and the polytetrafluoroethylene coatings are formed on the surfaces of the filter cloth with impregnation and drying curing methods. A filter bag prepared with the composite cloth has relatively high high-temperature resistance and wear resistance. During an application process, the bag breakage rate can be effectively reduced, and the service life of the filter bag can be prolonged.
Description
Technical field
The present invention relates to filtering material technical field, especially a kind of high temperature resistant composite filtering cloth for industrial dust collector.
Background technology
At present, usually there is the problem that broken bag rate is high, service life is short in the filter bag for the industrial dust collector of coal-burning power plant and metal smelt industry.This problem mainly can not keep enough intensity due to existing filter pocket material, not wear-resistantly to cause in hot environment, the such as normally used terylene of existing filter bag and aramid fiber material etc.Thus causing the maintenance cost of existing deduster higher, dust removal by filtration effect is affected.
Summary of the invention
For the deficiency of above existing filter pocket material, the object of this invention is to provide a kind of high temperature resistant composite filtering cloth, the filter bag adopting this composite filtering cloth to make has high temperature resistant and anti-wear performance preferably, effectively can improve the service life of filter bag.
The object of the invention is by realize by the following technical solutions:
High temperature resistant composite filtering cloth, comprise Ji Bu and carpet veneer, described base cloth comprises glass fabric, and a side or the two sides of described base cloth are respectively equipped with carpet veneer, and described carpet veneer comprises glass fibre, basalt fibre, ceramic fibre or formed by the two or more fibers mixture in above-mentioned three kinds of fibers; Described Ji Bu and carpet veneer are overall structure by acupuncture composite joint.
As the preferred technical solution of the present invention, the surface of described base cloth is provided with polytetrafluorethylecoatings coatings.
As the preferred technical solution of the present invention, the surface of described carpet veneer is provided with polytetrafluorethylecoatings coatings.
As the preferred technical solution of the present invention, the thickness of described polytetrafluorethylecoatings coatings is 0.18 millimeter to 0.2 millimeter.
The invention has the beneficial effects as follows: relative to prior art, the present invention adopts glass fibre, basalt fibre, ceramic fibre to make composite filtering cloth, and form polytetrafluorethylecoatings coatings by the method for dipping and baking and curing on the surface of filter cloth, the filter bag adopting this Compound Fabric to make has stronger high temperature resistant and anti-wear performance, broken bag rate can be effectively reduced in use procedure, improve the service life of filter bag.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and specific embodiment, the invention will be further described:
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
As shown in Figure 1, high temperature resistant composite filtering cloth, comprise base cloth 1 and carpet veneer 2, described base cloth 1 comprises glass fabric, the two sides of base cloth 1 are respectively equipped with carpet veneer 2, the material of described carpet veneer 2 comprises glass fibre, basalt fibre, ceramic fibre, or is formed by the two or more fibers mixture in above-mentioned three kinds of fibers; Described base cloth 1 and carpet veneer 2 are overall structure by acupuncture composite joint.
In the present embodiment, described base cloth 1, by the method for dipping ptfe emulsion, forms polytetrafluorethylecoatings coatings on its surface.Described carpet veneer 2 is mixed with the ptfe emulsion of wear-resisting micro mist by dipping, then after drying and solidification, form PTFE anti-wear coating 3 on its surface, the thickness of PTFE anti-wear coating 3 is 0.18 millimeter to 0.2 millimeter.
