Description
The present invention relates to warp-knitted fabric of making by the silk that contains noble metal and the ventilative method of making by the silk that contains noble metal with knitting machine mechanization production through the netting lattice.
By the knit materials made of silk that contains noble metal with and production method known already, for example, the catalysis grid of being made by the platinum-rhodium wire of thickness between 60～120 μ m is used to make the burning of ammonia to be subjected to catalytic action to generate nitric acid.In corresponding burner, adopt the catalysis grid, for example, the edge will be by the horizontal employing catalysis grid of the flow direction of the ammonia of catalyzed conversion, because the efficient that is obtained in catalyst depends on the size of the Free Surface that scribbles the effective material of catalysis substantially, the characteristic of these catalysis grids is the possible surface area of its maximum.Yet, simultaneously, wish to hinder air-flow as small as possible, in other words, gas-flow resistance is low as far as possible.
Usually, these catalysis grids, are cut into required size then and make by they are made into net by corresponding precious metal.Yet with regard to a machine-knitted structure, the wire of intersection only forms the coil of double-layer structure, has been found that such woven material makes air-flow have high relatively resistance with respect to the surf zone that is provided.In addition, owing to need load to loom, the woven of such catalysis grid is consuming time relatively, and owing to the limited toughness of comparing precious metal with textile fabric also must be carried out at leisure.
EP-A10364153 has described catalysis grid and the method that allegedly can eliminate these shortcomings.Proposed to be used for producing the grid of precious metal alloys therein, especially in the method that the burning of the ammonia of catalysis and noble metal reclaim, the precious metal alloys silk carries out weft knitting with the boost line of being made by natural fabric or plastics on weft-knitting machine.The running-on that forms during weft knitting produces one three layer line circular structure, and this structure forms than woven big Free Surface zone with regard to similar face weight.Yet,, can there be boost line and weft-knitted pure precious metal alloys silk in weft-knitted process because silk ruptures with regard to this method.Yet the shortcoming that has boost line is must remove this boost line before using grid.
The silk that has proposed to be used for to be made by platinum or palldium alloy by weft knitting in DE-C14206199 on the flat pattern weft machine is produced the similarity method of the ventilative grid that noble metal makes.Yet the intensity and the toughness applicability that also limited this method that contain the silk of noble metal, so, this method be only applicable to weft knitting by diameter between 50～120 μ m TENSILE STRENGTH at 900-1050N/mm
2Between platinum-rhodium, platinum-palladium-rhodium, palladium-nickel, the silk that palladium-copper and palladium-nickel-copper alloy are made.
Usually, use the known weft-knitted method of flat pattern weft machine can only produce thick relatively mesh knitted structure, so, low specific area and mechanism performance instability had according to these structures of volume of this knit materials.Though the fine mesh metal grill can be produced by circular knitting machine, its fabric width is restricted to less than 3 meters by the circular knitting machine that is suitable at present.
The method of in WO92/02301, having described such warp-knitted fabric and having produced this fabric.It discloses catalysis and has reclaimed grid, and these grids make and adopt warp knitting machine to form with open type warp plain stitch (tricot) by the silk that contains noble metal.
In warp-knitting and weft-knitting, these are had at least three layers loop construction by lopping with formation, with regard to similar face weight with knitting than with the bigger surface area of woven acquisition.Yet, with regard to known warp-knitting method, can only form the grid of pine relatively with little rigidity, particularly, the characteristics of the warp-knitting structure that forms with open type warp plain stitch are to have low relatively DIMENSIONAL STABILITY and be easy to displacement, and because occupied this structure of volume of warp-knitted fabric has low relatively specific area.In order to strengthen open type warp plain stitch, WO92/02301 has proposed the compound coil of relative complex, and it for example can be produced through the volume technology with La Sheer or the jacquard weave of Jacquard formula.Because compare the toughness of the silk that contains noble metal and stretching and bending strength with textile fabric low, so the knitting technology weave that has high strength to require very much to silk can only be produced limited degree or only with low knitting speed production.So, in a preferred embodiment, the silk that contains noble metal with a bronze medal boost line or with synthetic fiber through compiling, perhaps in another operation during knitting the coated lubricant.This design is in order to protect silk to avoid possible mechanical failure.
Main purpose of the present invention provides by the silk that contains noble metal and makes and have the warp-knitted fabric of high-specific surface area and fine mesh and good mechanical stability and a straightforward procedure of producing this knitted fabric.
Above-mentioned purpose is to finish by the following fact with regard to warp-knitted fabric according to the present invention, be that warp-knitted fabric has the coil of remaining silent (stitches), the per inch row has at least 14 coils, and at least one coil (loops) of formed warp-knitted fabric has underlap, wherein, each sinker loop strides across at least two wales.
Hereinafter " coil " is interpreted as being meant bonding coil mutually, and these coils keep its shape with following reversal point place by other coil thereon.The loop density for example the shortest connection between the last reversal point of the coil of the adjacent stringer by coil is determined." row " refers to each other laterally adjacent coil, and " stringer " formed by coil of arranging on another in the adjacent windings line.Adjacent row is provided with silk by the reversal point from a coil to a new coil and is connected with each other.When silk is configured to not only row but also stringer when also being connected with each other, its result forms the warp-knitted fabric of being made up of the coil of the parallel type structure that is connected with each other.Show, when the silk that contains noble metal at least one maille that is forming warp-knitted fabric is arranged to stride across at least three loop densities, obtain warp-knitted fabric with enough mechanical stabilities.Together with the embodiment with the coil of remaining silent, this makes warp-knitted fabric have the vertical and horizontal stability of height, and this high stability is operation and be convenient to the processing of back between the operating period afterwards.In addition, setting strides across at least three needle gages closely knit warp-knitted fabric with high superficial density that produces at interval, what proved necessity is, even when many mailles are bonded in the warp-knitted fabric, for example resemble the such characteristic of intensity, expansivity, elastic force or surface weight in order to improve, in at least one maille underlap is set, wherein, each sinker loop strides across the coil of at least two stringers.
The structure that has the warp-knitted fabric of the coil of remaining silent makes fabric have high mechanical stability, is convenient to its production and processing in operation afterwards and the practical application.
Be set at least 14 coils of per inch by coil number, make warp-knitted fabric have fine mesh structure, this structure can obtain extra high surface weight.Together with by the formed loop construction with at least three layers of warp-knitting, warp-knitted fabric has extra high specific area according to the occupied volume of this fabric.
With regard to fine mesh structure, verified particularly advantageous is that warp-knitted fabric has the coil number in the scope between 18 coils of per inch and 32 coils of per inch.
Verified this warp-knitted fabric is successful especially, wherein, in this warp-knitted fabric, in at least one maille that forms this warp-knitted fabric, underlap is set, each sinker loop strides across the coil of three stringers, the silk that contains noble metal of She Zhiing by this way, the warp-knitted fabric that especially has compound maille has very high horizontal and vertical stability and extra high surface weight.
Advantageously, this warp-knitted fabric by contain noble metal and the silk of diameter between 50 μ m and 200 μ m make.Especially under the situation of the warp-knitted fabric of main platiniferous, verifiedly advantageously use the silk of diameter between 60 μ m and 76 μ m, and the silk that contains palladium also can use thicker diameter.
With regard to its method, according to the present invention, aforementioned purpose realizes by the following fact, promptly, use has per inch has the warp knitting machine of the needle gage of at least 14 coils to contain the silk of noble metal through volume, the formation coil of remaining silent is so that at least one maille that forms warp-knitted fabric, the underlap of each sinker loop strides across at least two needle gages at interval.
The embodiment that has the warp-knitted fabric of the coil of remaining silent makes this fabric have high mechanical stability, this is in itself needs again in the volume process, so that can bear especially when the production wide screen in order to make the abundant and firm required high material pulling force of web material bending.In addition, the high mechanical properties of the warp-knitted fabric that obtains by this way and stability make and handle easily in afterwards operation and practical application.Be unexpectedly, have been found that by can satisfying the intensity of the silk that in coil is remained silent in production, contains noble metal and the requirement of toughness through compiling standard material, so, about this point without limits to method of the present invention.
The needle gage of warp knitting machine is arranged on per inch at least 14 pins can forms fine mesh structure, allow to produce warp-knitted fabric with extra high surface weight, together with by through compiling at least three layers the knitted structure of having form, can obtain the warp-knitted fabric that has extra high specific area according to the occupied volume of this warp-knitted fabric.
Have been found that when the underlap of each sinker loop at least one maille that is forming warp-knitted fabric strides across two needle gage spacings the warp-knitted fabric that can obtain to have enough stability at least.Together with the embodiment with the coil of remaining silent, this makes this warp-knitted fabric have high vertical and horizontal stability, and this is convenient to the processing through volume and warp-knitted fabric afterwards again.In addition, stride across at least three needle gages underlap at interval and produce closely knit warp-knitted fabric with high superficial density.What proved necessity is, in at least one maille, stride across the underlap at least three needle gages intervals for the silk setting that contains noble metal, in addition mutually compound with many mailles in a warp-knitted fabric for example so that improve intensity, expansivity, elasticity or surface weight.
Advantageously, if in the volume process between 50mN and 300mN, more fortunately between 70mN and the 150mN in the scope basically uniformly tension force act on this silk.These tension force guarantee to be positioned at the reliable knocking over of coil on the needle point of warp knitting machine, and the silk that does not contain noble metal bore the component of stress and the such danger of fracture, and allow to form abundant stable warp-knitted fabric.In order to produce warp-knitted fabric as far as possible the most closely, it is lower that the material tensioning keeps.
Warp knitting machine is configured to have the needle gage in the scope between 18 coils of per inch and 32 coils of per inch, with with regard to warp-knitted fabric suffered as far as possible little power when the pin of warp knitting machine is left behind is considered, the used method of this warp knitting machine has proved particularly advantageous with regard to fine mesh structure.
