Abstract
The utility model discloses a kind of two composition gradient high temperature high efficiency filtrate, filtrate is three layers of complex structure, three layers of complex structure ecto-entad comprise surface layer successively, supporting layer and bottom, surface layer is by P84 fiber, ultra-fine NOMEX fiber and PTFE fiber three kinds of fibers are through shredding, mixing, the lamina reticularis body that combing is tangled, supporting layer by PTFE fiber through woven machine-woven fabric layer body, bottom is through shredding by NOMEX fiber and PTFE fiber two kinds of fibers, mixing, the lamina reticularis body that combing is tangled, surface layer, supporting layer and bottom link reinforcing together mutually by acupuncture.The utility model has the following advantages compared to existing technology: while, strainability high in the surface layer structure, the guarantee media filtration precision that improve filtrate is good, improve the resistance to elevated temperatures of filtrate, long service life, has saved production cost, has improve service efficiency.
Description
Technical field
The utility model relates to a kind of air filting material, in particular a kind of two composition gradient high temperature high efficiency filtrate.
Background technology
Along with Chinese Industrialization progress faster, air pollution becomes the focus that everybody pays close attention to day by day, PM2.5 is as air-polluting " arch-criminal ", and need to be filtered it by filtering material, filtering material has been widely used in the industrial circles such as generating, fire coal at present.But under at present complicated at some working conditions, temperature is higher, filtering accuracy requires strict environment, ordinary filter can not meet its requirement.In order to improve filtering accuracy, heat-resisting quantity, people utilize high-performance fiber constantly to improve the stuctures and properties of filtrate, thus obtain satisfactory high efficiency filter material.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of two composition gradient high temperature high efficiency filtrate.
The utility model is achieved through the following technical solutions:
A kind of two composition gradient high temperature high efficiency filtrate, described filtrate is three layers of complex structure, described three layers of complex structure ecto-entad comprise surface layer successively, supporting layer and bottom, described surface layer is by P84 fiber, ultra-fine NOMEX fiber and PTFE fiber three kinds of fibers are through shredding, mixing, the lamina reticularis body that combing is tangled, described supporting layer by PTFE fiber through woven machine-woven fabric layer body, described bottom is through shredding by NOMEX fiber and PTFE fiber two kinds of fibers, mixing, the lamina reticularis body that combing is tangled, described surface layer, supporting layer and bottom link reinforcing together mutually by acupuncture.
As the preferred embodiment of a kind of pair of above-mentioned composition gradient high temperature high efficiency filtrate, described surface layer and bottom are all the lamina reticularis bodies based on PTFE fiber.
As the preferred embodiment of a kind of pair of above-mentioned composition gradient high temperature high efficiency filtrate, described surface layer is identical with PTFE fiber proportion in bottom.
As the preferred embodiment of a kind of pair of above-mentioned composition gradient high temperature high efficiency filtrate, the grammes per square metre of described supporting layer is 100-300g/m
2.
The utility model has the following advantages compared to existing technology:
The two composition gradient high temperature high efficiency filtrate of the one that the utility model provides, the PTFE fiber that its surface layer, supporting layer and bottom all contain has resistant to elevated temperatures feature; P84 fiber has very large filter table area, joined in surface layer, can ensure that filtrate fully contacts with dust, play the advantage that its specific area is large, filtering accuracy is high, and effective reduction equipment running resistance, ensure that the strainability of filtrate excellence, P84 fiber also has superior resistance to elevated temperatures simultaneously; In addition, NOMEX fiber good heat resistance, intensity are high; P84 fiber, ultra-fine NOMEX fiber and PTFE fiber are combined as surface layer, NOMEX fiber and PTFE fiber are combined as bottom, using PTFE fiber as supporting layer, while, strainability high in the surface layer structure, the guarantee media filtration precision that improve filtrate is good, improve the resistance to elevated temperatures of filtrate, long service life, has saved production cost, has improve service efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below embodiment of the present utility model is elaborated; the present embodiment is implemented under premised on technical solutions of the utility model; give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
See Fig. 1, the two composition gradient high temperature high efficiency filtrate of the one that the present embodiment provides, filtrate is three layers of complex structure, and three layers of complex structure ecto-entad comprise surface layer 11, supporting layer 12 and bottom 13 successively, and surface layer 11 and bottom 13 are all the lamina reticularis bodies based on PTFE fiber.Surface layer 11 is the lamina reticularis body tangled through shredding, mixing, combing by P84 fiber, ultra-fine NOMEX fiber and PTFE fiber three kinds of fibers, bottom 13 is the lamina reticularis body tangled through shredding, mixing, combing by NOMEX fiber and PTFE fiber two kinds of fibers, and surface layer 11 is identical with PTFE fiber proportion in bottom 13.Supporting layer 12 is by PTFE fiber through woven machine-woven fabric layer body, and the grammes per square metre of supporting layer 12 is 100-300g/m
2.Surface layer 11, supporting layer 12 and bottom 13 link reinforcing together mutually by acupuncture.
The two composition gradient high temperature high efficiency filtrate of the one that the present embodiment provides, the filtrate shortcoming that under high temperature, temperature tolerance is poor more than 180 DEG C, filtering accuracy is low avoiding needled conventionally legal system standby, improve the resistance to elevated temperatures of filtrate, filtering accuracy and extend service life, the moderate cost of this filtrate simultaneously, can save production cost to a certain extent, enhance productivity.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
