Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jig for measuring the coating amount distribution of a combustion catalyst substance on a metal carrier by a coating device, a catalyst substance coating amount distribution measuring method used for the jig, and the coating amount distribution measuring device. The present invention relates to a method for processing a metal ultra-thin plate and a processing roll to which the method is applicable.

2. Description of the Related Art As one of the conventional methods for supporting a combustion catalyst substance on a metal carrier, as shown in FIG. 6, a stainless steel strip 2 is fed from an uncoiler 1, and then a spray nozzle 3 is used to wash coat (ceramics + fine acid). Water) and a catalyst solution coat (PtP salt, PdP salt, or a mixture thereof), followed by drying through an oven 4, followed by baking and then cutting to the required length.
When the thickness of the catalyst of the catalyst-supported metal carrier thus obtained was measured by gravimetric analysis and chemical quantitative analysis, it was found that many were non-uniform. Therefore, it is required to be as uniform as possible.

By the way, in the above-mentioned method for measuring the thickness of the catalyst, the pass / fail judgment cannot be made without measuring one lot (long material), and the yield is poor and the measurement efficiency is low. On the other hand, a porous ceramics (alumina) or a honeycomb structure made of metal has been mainly used as the metal carrier carrying the combustion catalyst substance or the exhaust gas purifying catalyst as described above. By the way, these porous ceramics and metal honeycomb structures take time and effort to carry the catalyst, and it is difficult to carry them uniformly.

From the above, a corrugated metal ultrathin plate 5'as shown in FIG. 7 is coated with a carrier layer carrying a catalyst, which is wound and laminated as shown in FIG. Has been developed. However, since the corrugated metal ultra-thin plate 5'is formed by the continuous processing of a single press die or the single die roll machining, the corrugation does not proceed neatly and the corrugation 7'is not formed in the plane longitudinal direction. It became continuous or the plane refraction pattern 6'was discontinuous in the width direction. Therefore, if a honeycomb layer is formed by coating the carrier layer with a carrier layer as shown in FIG. 8 and forming a honeycomb 8, the gap 8a between the stacks may become large or small, and the gap may disappear due to the close contact. There was a problem that it decreased.
Also, the forming efficiency of the corrugated metal ultra-thin plate 5'was poor.

[0005]

In view of the above-mentioned drawbacks of the prior art, the present invention provides a jig for simply measuring the distribution state of the coating amount of the catalyst substance on the strip, and a measuring method using the jig. An object of the present invention is to provide a corrugating method for corrugating a plane refraction pattern on a metal ultrathin plate for supporting a combustion catalyst substance and a processing roll to which the measuring jig and the measuring method are applied.

The catalyst substance application amount distribution can be measured by setting the catalyst substance so that it is positioned, spraying the catalyst substance, and measuring the amount of the liquid to be sprayed in each cell of the catalyst substance application amount distribution measuring jig.

Further, the corrugated roll having a plane continuous refraction pattern of the present invention has a tooth profile roll having an outer peripheral tooth profile inclined at a constant angle with respect to the axial direction, and an outer peripheral tooth profile on the opposite side to the tooth profile roll in the axial direction.

Combining adjacently, passing the band-shaped metal ultra-thin plate between the adjacent processing rolls, and performing corrugation of the plane continuous refraction pattern on the metal ultra-thin plate, corrugation of the plane continuous refraction pattern to the metal ultra-thin plate is performed. it can.

The details of the present invention will be described below. First, when the above-mentioned catalyst substance coating amount measurement jig is used, the catalyst substance that has entered each cell of the jig by spray coating is collected with a dropper and the weight is measured, so that the catalyst substance can be easily coated. The quantity distribution is known. Further, if the rectangular parallelepiped container of the jig is a container in which both sides of at least a plurality of partitioned cells are transparent, the coating amount thickness can be easily determined visually.
In particular, when the partitioning direction of the container is set parallel to the uncoiler feeding direction, the distribution of the coating amount of the catalyst substance in the width direction can be easily determined and the catalyst substance can be easily taken out.

Further, according to the above-described corrugation processing direction of the plane refraction pattern, since the corrugation processing of the plane refraction pattern can be continuously performed on the strip-shaped metal ultrathin plate, the metal ultrathin plate can be efficiently formed and the productivity is improved. To do. Further, the precision of corrugating the plane refraction pattern is also improved, and the corrugation can be performed easily and surely. Further, when the above-mentioned processing roll is used, the plane refraction pattern can be surely and stably formed on the ultrathin metal plate in the same manner.

A transparent vinyl chloride container 10 having a width of 130 mm, a height of 110 mm, and a wall thickness of 6 mm is provided with a vinyl chloride partition 11 having a thickness of 1 mm so as to have an even area when viewed from the upper surface. Further, each partitioned cell 12 is liquid-tightly insulated and isolated from the adjacent cell so that the liquid does not move, and a catalyst substance coating amount measuring jig 13 is constituted.

As shown in FIG. 2, the jig 13 is fed from the uncoiler 1 with a width of 3 inches (about 7.6 cm) and a thickness of 50 μm.
The catalyst material is set so as to be located at the same height as the stainless steel strip material 2 and sprayed with ceramics + slightly acidic water, PtP salt, and PdP salt from the spray nozzle 3. A pattern having a distribution is drawn and enters each cell 12 of the measuring jig 13. Therefore, the liquid to be sprayed was collected (sampled) from each cell 12 of the measuring jig 13, and the weight in each cell 12 was measured. From this, the distribution of the coating amount of the catalyst substance was easily found.

Further, since the rectangular parallelepiped container 10 of the measuring jig 13 is made of transparent vinyl chloride, the container can be easily manufactured, and the distribution of the coating amount of the catalyst substance in the width direction can be easily determined.
It is also easy to take out the catalyst substance. It is preferable that each partitioned area is 1/30 to 1/5 of the total area. If it is less than 1/30, it will be difficult to collect (sampling) the liquid to be sprayed, and This is because if it exceeds, it will be difficult to grasp the exact distribution.

As a pattern 26 in which the light was continuously bent 5 times at intervals of 15 mm from the both sides in the width direction, a corrugated cross-section with a height of 1.9 mm and a pitch of 2.5 mm was applied. When the corrugated stainless steel foil 25 was inspected in this way, the planar refraction pattern 26 was continuous without interruption in the width direction, and the cross-sectional waveform 27 in the longitudinal direction was not interrupted at a constant pitch. In addition, the waveform 27 was continuous without change and was extremely accurate.
