Abstract
The invention relates to a method for producing a wire mesh fibrofelt compound filter disc, which comprises the following steps of: processing metal fibers by using metal wires or metal alloys, knitting the metal fibers into a wire mesh, superposing fibrofelts with different filtering precision values and the wire mesh, placing the fibrofelts and the wire mesh which are superposed together into a vacuum sintering furnace or a protective atmosphere with a reducing property to sinter the fibrofelts and the wire mesh which are superposed at the temperature of 1,100 to 1,500 DEG C, and preserving the heat for 1 to 5 hours; performing cooling, rolling the sintered wire mesh fibrofelt compound filter disc by using a rolling mill to adjust a thickness, and finally obtaining the wire mesh fibrofelt compound filter disc in a stamping or cutting way. The wire mesh fibrofelt compound filter disc simultaneously has filtering resistance lower than that of a wire mesh filter, and the high filtering precision, high mechanical strength index and low production cost of the fibrofelt, and is an ideal material for filtering high-viscosity materials in a high-temperature environment.
Description
Technical field
The invention belongs to the filter plant production technical field, relate to a kind of production method that is widely used in the wire netting fibrofelt combined filtration sheet of industrial circles such as chemical industry, medicine, generating, metallurgy and food, this wire netting fibrofelt combined filtration sheet especially is adapted to the fine filtering of high-viscosity material under the chemical industry hot conditions, and is widely used in the manufacturing field of chemical industry fiber.
Background technology
All need fiber is fully removed by filter all particulate matters before wire drawing in the chemical fibre field of making, otherwise will fracture of wire in drawing process, occur, have a strong impact on the stability of production, and increase production cost, and bring great difficulty to production.This filtration requires high filtering accuracy, because filter material is operated under the hot conditions, has very high viscosity simultaneously, therefore can only use the filtering material of the low filtration resistance of wire netting silk screen class.Because this filtering material is behind the trapped particles material, self can be stained with filter material, and this material can't clean in the cooling after-hardening, thus can only be disposable product, thereby just need a kind of efficient, low-cost, high-intensity filtering material.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art, the invention provides a kind of production method with wire netting fibrofelt combined filtration sheet of low filtration resistance, high filtering precision and the high slight index of mechanics and low production cost.
The present invention solves the technical method that its technical problem adopts: a kind of production method of wire netting fibrofelt combined filtration sheet, earlier wire or metal alloy are processed into metallic fiber, then metallic fiber is woven into wire netting, fibrofelt and wire netting with different filtering accuracies is superimposed together again, after stack, the protective atmosphere of putting into vacuum sintering furnace more together or having a reducing property carries out sintering, and sintering temperature is 1100-1500 ℃, and temperature retention time is 1-5 hour; After cooling, the wire netting fibrofelt combined filtration sheet behind the sintering is suppressed and regulated thickness through milling train again, the form by punching press or shearing obtains wire netting fibrofelt combined filtration sheet at last.
The employed material of described metallic fiber has the elemental metals silk of Fe, Co, Ni, W, Mo, Cr, Cu, Al, Ti, Sn, Ta, Nb, Zr, or by the formed alloy of these metallic elements.
Described wire netting fibrofelt combined filtration sheet is composite metal nets all on the one side of metal fiber felt or two sides, and sintering obtains then.
Described wire netting fibrofelt combined filtration sheet is to be obtained by one deck or which floor wire netting and metal fiber felt stack.
The invention has the beneficial effects as follows: adopt wire netting fibrofelt combined filtration sheet to have the low filtration resistance of relative metal cloth filter simultaneously, having the high filtering precision of fibrofelt and high slight index of mechanics and low production cost simultaneously, is the desirable filtering material of high-viscosity material under the hot environment.
