In order to overcome the problem that prior art exists, the purpose of this utility model provides a kind of inorganic-fiber ultra-high temperature composite filter material, this composite filter material has overcome the shortcoming that cohesive force is poor, peel strength is low between traditional pure basalt or the ceramic fiber blanket, it is big also to have overcome simple metal fibrofelt hardness, unpliant shortcoming, cohesive force is strong, can bear higher filtration velocity, long service life.
Summary of the invention
The purpose of this utility model is achieved through the following technical solutions:
A kind of inorganic-fiber ultra-high temperature composite filter material is characterized in that: this composite filter material comprises base cloth layer and carpet veneer, and described base cloth layer is positioned between the two-layer carpet veneer; Described base cloth layer is an inorfil; Carpet veneer is the stainless steel double condensating fiber.
Inorfil described in the utility model is basalt fibre or ceramic fibre.
Described stainless steel double condensating fiber is mixed by stainless steel fibre and basalt fibre or stainless steel fibre and ceramic fibre, and wherein the stainless steel fibre ratio is 10-30%.
In the utility model, stainless steel double condensating fiber and inorfil adopt the molten sintering method to combine, and the stainless steel double condensating fiber is being bonded in the inorfil base cloth on the intertwined point of weft yarn after the fusion under 1500 ℃ the high temperature.
In the utility model, inorfil is short fiber or long filament base cloth.The stainless steel double condensating fiber is a short fiber.
The utility model preparation process is:
The making of base cloth layer: adopt basalt fiber long filament or ceramic fibre long filament,, be processed into 330~560g/m through warp and weft interweaving 2Base cloth.
The making of carpet veneer: carpet veneer adopts stainless steel short fiber and basalt fibre blending, and ratio is that metallic fiber accounts for 10-30%, through forming 100~250g/m after shredding, the combing 2The metal composite fiber carpet veneer.
Under 1500 ℃ high temperature, make metallic fiber be melted in that welding forms node on the longitude and latitude intertwined point of base cloth by the molten sintering method, thereby form evenly extra-high-speed temperature basalt fibre composite felt closely.
The utility model is with basalt or ceramic short fiber or long filament base cloth, carpet veneer is that basalt fibre mixes with stainless steel fibre or adopts ceramic fibre to mix with stainless steel fibre, by the high-temperature fusion sintering process, temperature is reached more than 1500 ℃, stainless steel double condensating fiber sintering is welded on basalt fibre base cloth or ceramic fibre base cloth, form node, make the inorfil high-temperature composite filter material.
The utility model is fixed on the stainless steel double condensating fiber on the basalt base cloth by sintering process, overcome the shortcoming that cohesive force is poor, peel strength is low between traditional pure basalt or the ceramic fiber blanket, it is big also to have overcome simple metal fibrofelt hardness, unpliant shortcoming, high-sintering process has overcome the shortcoming that traditional employing surface chemical treatment agent is at high temperature decomposed, can bear higher filtration velocity, increase the service life.
