Abstract
A kind of manufacture method of iron-chromium-aluminum metal fiber filter material, key step comprises the shearing and the shredding of fibrous raw material, iron-chromium-aluminum metal fiber suede is put into the cylinder of shop felt machine, simultaneously the siderochrome aluminium sheet of surface brush alumina powder of oven dry is taped against on the track of felt machine and begins the system of spreading, the metallic fiber of having completed is put into vacuum burning felt stove together with the siderochrome aluminium sheet; The metallic fiber sintered felt that takes out is adopted the roll extrusion leveling with evener.The present invention has remedied that ceramic frangible, silk screen is easily stifled, filter cloth filter paper non-refractory, defective such as not withstand voltage; Adopt multilayer vibrations technology: can force metallic fiber fully fluffy, guarantee all stability of even filtering accuracy of gradient; The roll extrusion flattening course has all been brought into play certain repairing effect to high density bright spot, hard spot that nonwoven shop system process produces; Filtering material can and be worked in the pressure environment greatly at 800-1200 ℃ high temperature.
Description
Technical field
The invention belongs to environment-friendly materials and prepare scope, particularly a kind of manufacture method of iron-chromium-aluminum metal fiber filter material.
Background technology
The metallic fiber filtering material generally by stainless steel fibre, nickel fiber through high temperature and vacuum protection sintering in sintering furnace forms; The filtration that Stability Analysis of Structures, corrosion resistance are good, high temperature resistant, the sintering felt behind oversintering can keep filter net cloth continuously of stainless steel sintering felt has that three netted, loose structures, porosity height, surface area are big, a pore size, the characteristics that are evenly distributed; Traditional technology generally adopts the rigid extruding of hydraulic press, and the high density point piece that meets the system process generation of nonwoven shop very easily extrudes bright spot, and this bright spot in use will cause hole, have a strong impact on product quality.Siderochrome aluminium filtering material, have superior gas permeability and capillary function, high temperature resistant, high pressure, it is the preferred material of diesel locomotive exhaust purifier, the petroleum gas burner energy-conserving and environment-protective of manufacturing, its goods can be regenerated, the life-span is long, are to substitute one of pottery, braiding silk screen, filter cloth, filter paper desirable feedstock
Summary of the invention
At above defective, the purpose of this invention is to provide a kind of by 100% micron order iron-chromium-aluminum metal fiber, the manufacture method of the iron-chromium-aluminum metal fiber filter material of a kind of novel porous, the gradient layer body that forms through nonwoven shop system, vacuum high-temperature sintering can be worked this filtering material in 800-1200 ℃ high temperature and big pressure environment.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of manufacture method of iron-chromium-aluminum metal fiber filter material, the step such as shop system, roll extrusion leveling that mainly comprises the shearing of fibrous raw material and shredding, siderochrome aluminium sheet, concrete steps are: 100% micron order iron-chromium-aluminum metal fiber is cut into the length of technological requirement, put into the opener shredding then; Iron-chromium-aluminum metal fiber suede is put into the cylinder of shop felt machine, simultaneously the siderochrome aluminium sheet of surface brush alumina powder of oven dry is taped against on the track of felt machine and begins the system of spreading, the metallic fiber of having completed is put into vacuum together with the siderochrome aluminium sheet burn the felt stove, furnace temperature is set to the temperature of technological requirement, by the time the regular hour, felt is got in blow-on; The metallic fiber sintered felt that takes out is adopted the roll extrusion leveling with evener, cut limit, scale again, can pack after weighing.
The beneficial effect of the manufacture method of iron-chromium-aluminum metal fiber filter material of the present invention is: iron-chromium-aluminum can replace pottery, mesh grid, filter cloth, filter paper to make the filtration utensil, thereby remedies that frangible, the silk screen of pottery is easily stifled, filter cloth filter paper non-refractory, defective such as not withstand voltage; Enlarged the filter application face to a certain extent, increased the service life; Nonwoven shop filter made material adopts multilayer vibrations technology: promptly every layer of vibrations mesh screen adopts different apertures, different shake frequently, forces metallic fiber fully fluffy, guarantees all stability of even filtering accuracy of gradient; The levelling process of utilization filtering material behind sintering both guaranteed that filtering material was smooth, at the roll extrusion flattening course high density bright spot, hard spot that nonwoven shop system process produces all brought into play certain repairing effect again; This filtering material can and be worked in the pressure environment greatly at 800-1200 ℃ high temperature.
The specific embodiment
The manufacture method of iron-chromium-aluminum metal fiber filter material of the present invention mainly may further comprise the steps:
(1) 100% micron-sized iron-chromium-aluminum metal fiber is cut into the length of technological requirement, put into the opener shredding then, mainly comprise: the iron-chromium-aluminum metal fiber tow of 100% micron-sized abundant stretching is broken through shearing made the short fiber tow, again the metallic fiber raw material that compresses or tangle is mutually loosened and removal of contamination;
(2) iron-chromium-aluminum metal fiber suede is put into the cylinder of spreading the felt machine, the siderochrome aluminium sheet that to brush the skin drying of alumina powder simultaneously is taped against on the track of felt machine and begins the system of spreading, the metallic fiber of having completed is put into vacuum together with the siderochrome aluminium sheet burn the felt stove, the temperature that furnace temperature is set to technological requirement is as 1300 ℃, by the time the regular hour again blow-on get felt, mainly comprise: adopt the multilayer vibrations to do the shop mode, shake speed by multilayer more, fully the shake pine spreads fiber suede, evenly spread every layer of vibrations of system mesh screen and be set to different apertures and different shake frequency, make metallic fiber fully fluffy to guarantee all stability of even filtering accuracy of gradient, the metal composite fiber net of completing is incubated behind 1300 ℃ high temperature sintering;
(3) metallic fiber sintered felt that takes out is carried out the roll extrusion leveling with evener, cut limit, scale more successively, can pack after weighing, mainly comprise: adopt the roll extrusion technology to make the multi-gradient hole evenly distribute, enlarge filter area, improve filter efficiency, both guaranteed that filtering material was smooth, at the roll extrusion flattening course high density bright spot or hard spot that nonwoven shop system process produces had been brought into play certain repairing effect again.
The advantage that more than shows and described principal character of the present invention and had.The technical staff of the industry should understand, and the present invention is not restricted to the described embodiments, and the present invention also has some variations and improves under the prerequisite that does not break away from purport of the present invention and scope, and these changes and improvements all fall in the claimed scope of the invention.
