Ultrahigh-pressure metal fiber sintered felt and preparation method thereof

Abstract

The invention discloses an ultrahigh-pressure metal fiber sintered felt and a preparation method thereof, and relates to the technical field of metal fiber sintered felts. A second steel wire and a second clamping pin are arranged on a second frame, a second ball is arranged on the second steel wire, a first steel wire and a first clamping pin are arranged on a first frame, the first steel wire is provided with a first round ball, a third frame body is arranged between the first frame body and the second frame body, the third frame body is provided with a steel mesh, and the second bayonet lock is clamped into the first bayonet lock, so that the purposes of pressure resistance and ordered distribution are achieved. The sintered felt is reasonable and practical in structure, so the pressure resistance of the metal fiber sintered felt is increased, the pressed metal fiber is sintered more tightly, the working efficiency is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of metal fiber sintered felt, in particular to an ultra-high pressure metal fiber sintered felt and a preparation method thereof. Background technique [0002] As we all know, metal fiber sintered felt is widely used in the core field of industrial product production because of its superior material properties and medium incompatibility. Common metal fiber sintered felts include: 304L stainless steel fiber felt, 316L stainless steel fiber Felt, 310S stainless steel fiber felt, iron-chromium-nickel alloy fiber felt, Hastelloy fiber felt, etc., the above-mentioned common metal fiber sintered felts all have working condition restrictions: they can only be used in the working environment of pressure <35Mpa, the existing The metal fiber sintered felt is made of metal fiber meshes of different diameters by the metal fiber wires of the same material, and then prepared by compounding the metal fiber meshes of dif...

[0002] As we all know, metal fiber sintered felt is widely used in the core field of industrial product production because of its superior material properties and medium incompatibility. Common metal fiber sintered felts include: 304L stainless steel fiber felt, 316L stainless steel fiber Felt, 310S stainless steel fiber felt, iron-chromium-nickel alloy fiber felt, Hastelloy fiber felt, etc., the above-mentioned common metal fiber sintered felts all have working condition restrictions: they can only be used in the working environment of pressure <35Mpa, the existing The metal fiber sintered felt is made of metal fiber meshes of different diameters by the metal fiber wires of the same material, and then prepared by compounding the metal fiber meshes of different diameters. Under normal conditions, the metal fiber sintered felt is made of metal fibers of the same material. It is made of multi-layer composite (at least 2 layers). The working pressure of the existing metal fiber sintered felt is difficult to break through 35Mpa. In some special regenerated fiber application fields, the pressure condition that needs to be met is 50-60Mpa. If the metal fiber sintered felt It can meet its working conditions and will become the preferred filter element of the application manufacturer. The metal fiber filaments used in the metal fiber sintered felt are relatively thin, usually below 40 microns, and the monofilament strength is small. Most of the metal fiber sintered felts are made of metal fiber non-woven In the manufacturing process, the arrangement of the filaments is disorderly distribution. Such a molding structure makes the bonding force between the filaments different, which affects the final strength.
