Problems solved by technology
[0007] However, in the above-mentioned method of forming ribs, when the blade for forming ribs is continuously used, there is a problem that the comb teeth of the blades in contact with the paste film are worn out.
Due to the poor precision of the ribs formed by the vanes with worn comb teeth and the reduced height of the formed ribs, frequent replacement of the vanes is required

example 1
[0066] A soda lime-based glass substrate 10 having a diagonal length of 42 inches and a thickness of 3 mm was prepared. A ceramic paste was applied on the glass substrate 10 and then fired to form a ceramic primer layer with a thickness of 10 μm on the glass substrate. As shown in FIG. 2, a paste having a thickness of 350 μm is applied on the glass substrate 10 having an undercoat layer on the surface by screen printing, thereby forming a paste film 11.
[0067] On the other hand, a blade 12 made of stainless steel was prepared, in which the pitch of the comb teeth 12b was 360 μm, the gap w between the comb teeth 12b was 180 μm, the depth was 350 μm, the thickness was 0.1 mm, and the edge angle was 75 degrees ( Figure 4 with 5 ). The surface of the comb teeth 12b of the blade 12 is coated with a composite layer, in which hard particles in the form of silicon carbide particles are dispersed in nickel metal (FIG. 1). The composition of the composite layer is composed of 10% (volume...

Abstract
One object of the present invention is to provide a blade (12) for forming ribs (23) that is able to improve wear resistance; in order to achieve the object, the present invention provide a blade (12) for forming ribs (23) that forms ribs (23) either on the surface of a substrate (10) or via an undercoating layer (22) on the surface of a substrate (10) by moving a blade body (12) in a fixed direction relative to a paste film (11) in the state in which comb teeth (12b) formed on at least a portion of the periphery of said blade body (12) are penetrated into said paste film (11) formed on the surface of said substrate (10) to plasticly deform said paste film (11); wherein, the surface of said comb teeth (12b) formed on said blade body (12) that makes contact with said paste film (11) is coated with a compound layer in which hard particles are dispersed in a metal.
Description
Technical field [0001] The present invention relates to a blade for forming ribs and a production method thereof, which can easily and accurately form ribs in the production process of flat panel displays (FPD) such as plasma display panels (PDP) and plasma mark liquid crystal displays (PALC) (Ceramic fine ribs). Background technique [0002] In the past, in the first method of forming ribs in these FPDs, a rib-forming paste 2 containing glass powder was placed on a glass substrate 1 in a predetermined pattern by a thick film printing method, and several layers of the paste were applied. , And fire the paste after drying to form ribs 8 at predetermined intervals on the substrate 1, such as Picture 10 Shown. The height H of the rib 8 is usually 100-300 μm, the width W of the rib is usually about 50-100 μm, and the span S of the cavity 9 between the ribs is usually about 100-300 μm. [0003] In addition, the second method of forming ribs is the sandblasting method. In this method,...
