Abstract
The invention discloses a cluster drawing process capable of producing micron-sized nickel fibers, and provides a suitable sheathing material, a separant and an operable separation process. The micron-sized nickel fiber which can be felted, woven and easily mixed with plastics and the like can be produced by adopting the process.
Description
The present invention relates to a kind of boundling drawing process of producing micrometer nickel fibre.
Existing method of producing the nickel fiber has amorphous state method, powder slurry method, solution spin processes, chemical fibre nickel plating method etc., and the nickel fiber that these methods are produced all can not be used for weaving, and is difficult for mixing with plastics.The boundling drawing process has been applied to produce steel fibre, niobium three tin and vanadium three gallium superconductors, but fails to be applied to produce the nickel fiber.Mainly be to fail to find suitable interleaving agent and sheath material, fail to make rational separating technology.
The object of the present invention is to provide a kind of boundling drawing process can be used for weaving, and mix, also can become the nickel fiber of felt sintering easily with plastics to produce.
The object of the present invention is achieved like this:
The boundling drawing process is produced the nickel fiber and be may further comprise the steps:
1), covers metal release agent or the nonmetal interleaving agent of 0.03-0.5mm at the nickel wire outer surface;
2), the tens of or hundreds of nickel wires that scribble interleaving agent are packed in the sheath material, constitute recombination line, in the room temperature drawing;
3), the recombination line of drawing is heat-treated under 400 ° of-800 ℃ of conditions;
4), with the drawing again of the recombination line after the heat treatment, and repeat to heat-treat-drawing 1-10 time;
5), be assembled in the sheath material again with tens of little recombination lines that diminish to hundreds of drawings;
6), repeat drawing one heat treatment 1-10 time, until required size;
7), separate sheath material and interleaving agent, finished product nickel fiber.
Interleaving agent used herein has metal release agent, comprising iron and ferroalloy, aluminium and aluminium alloy, copper and copper alloy, also has nonmetal interleaving agent to comprise metal oxide, graphite, diatomite, talcum powder etc.In order to make nonmetal oxide can add a little adhesives, as waterglass, methylcellulose, carboxymethyl cellulose, glycerine, silicone oil etc. attached on the nickel wire.Some magnetic metal oxide can directly be adsorbed on the nickel wire.Sheath material used herein comprises iron and ferroalloy, aluminium and aluminium alloy, copper and copper alloy.
The sheath material that the first time, assembled several times assembling and back can be identical, also can be different.
Here the separation sheath material of indication and the separation method of interleaving agent comprise chemical corrosion method, electrolysis, Hydrolyze method and mechanical stripping method.
Nickel fiber with the production of above boundling drawing process is micron-sized, can be used for textile industry, as make the super-pressure screening clothing, can become the felt burn-back again, as be used to do the electrode of Ni-MH battery and high energy nickel separation cell, this fiber also mixes with plastics easily, and as making shielding plastic conductive plastics etc., and technology is simple.
Embodiment 1
The nickel wire of 80 φ 0.6mm is at its surface coverage interleaving agent (talcum powder): carboxymethyl cellulose: 0.2mm water=5: 1: 10), in No. 20 low carbon steel pipe jacket fibrous materials with its φ 12 * 1mm that packs into; Carry out the room temperature drawing; 600 ℃ of heat treatments, continue to repeat drawing-heat treatment 6 times then, move the recombination line external diameter to is 0.82 millimeter always.Behind the recombination line outer surface cleaning, drying with φ 0.82mm, pack in φ 14 * 1mm20 low carbon steel pipe sheath material again, adorn 100 altogether, carry out drawing-heat treatment then, and repeat 5 times, till the recombination line external diameter is 1.45mm.With sulfuric acid the mild steel sheath material is eroded, dissolving carboxymethyl cellulose and talcum powder mixture (hydrolysis) in water more promptly obtains 8000 core diameters and is 8 microns nickel fiber.
Embodiment 2
70 φ 0.82mm nickel wires, electroplating surface interleaving agent copper 0.1mm, pack in φ 12 * 1mm2 rustproof aluminum alloy sheath material, carry out drawing, about 600 ℃, heat-treat then, and repeat drawing-heat treatment 7 times, till this recombination line vertical pulling is 0.7mm to external diameter, again 102 this recombination lines are packed in φ 12 * 1mm rustproof aluminum alloy sheath material, carrying out drawing-heat treatment again and repeat 7 times, is 0.9mm until the recombination line external diameter, with the 25%NaOH aqueous solution rustproof aluminum alloy jacket is eroded, with electrolysis copper is removed again, promptly obtain the pure nickel fiber of 7.0 microns of 7140 core φ.
