Problems solved by technology
[0003] Curium porcelain is generally more effective for repairing cracks and fragments of ceramics, but there are great limitations in repairing gaps in ceramics, especially for large-scale gaps, it is necessary to repair both the mud base material and the surface glaze , it is difficult to repair; at the same time, due to the secondary processing and sintering, it is difficult to achieve a good fusion between the new hot patch and the original ceramic surface

Embodiment 1
[0048] see Figure 1-2 and Figure 6-7 , a kind of magnetic pressure glazing hot-replenishing process for repairing defects of ceramic mud embryos, comprising the following steps:
[0049] S1. Use a carving knife to chisel the notch on the ceramic to form a repair cavity 1 with a standard shape, and polish the inner wall of the repair cavity 1 to clean and dry;
[0050] S2. Embed a matching magnetic support seat at the bottom end of the repair cavity 1, prepare a pair of hot-melt permeable mold stickers 4, and embed one of the hot-melt permeable mold stickers 4 inside 1 and Corresponding to the hot-melt infiltrating material mold paste 4 on the magnetic support seat, filling the embryo mud bottom material into the repair cavity 1 to form the embryo material layer 5;
[0051] S3. Place another hot-melt seepage material die-sticker 4 on the outer end surface of the blank material layer 5 formed. Attach a layer of anti-seepage film sticker 2 that is magnetically set with the m...

Abstract
The invention discloses a magnetic pressure glazing and hot patching process for ceramic clay blank defect repair, and belongs to the technical field of ceramic repair. A pair of hot melt infiltration material mold stickers are embedded in a formed repair cavity, the pair of hot melt infiltration material mold stickers play a mold fixing role in filling of a blank clay backing material, the opposite surfaces of the pair of hot melt infiltration material mold stickers are provided with a magnetic attraction bearing seat and an anti-seepage film paste respectively, and the magnetic attraction effect of the magnetic attraction bearing seat and the anti-seepage film paste is utilized, so that the effects of pressing and reinforcing the blank clay backing material are achieved, and the situation that the repairing effect is influenced due to the fact that the blank clay backing material is too soft is effectively prevented; meanwhile, the pair of hot melt infiltration material mold stickers are further conductive to improving the mechanical strength of the blank layer, after sintering is completed, the magnetic attraction bearing seat and the anti-seepage film paste are removed, and glaze is smeared on the outer end faces of the pair of hot melt infiltration material mold stickers to form a glaze layer; and through bridge connection with the hot melt infiltration material mold stickers, the connection effect between the glaze layer and the blank layer is further enhanced, and the glaze layer and the blank layer are effectively prevented from falling off from the notch again.
Description
technical field [0001] The invention relates to the technical field of ceramic restoration, and more specifically relates to a magnetic pressure glazing hot repair process for repairing defects of ceramic mud embryos. Background technique [0002] After the ceramic products are fired, there will be many kinds of products with defects that do not meet the internal control of the enterprise and the national standards. Small defects in these products can be repaired. For the repair of ceramics, there is also a traditional method in our country, that is, "curium porcelain", which is a technique of repairing broken ceramics with metal "curiums" like staples. [0003] Curium porcelain is generally more effective for repairing cracks and fragments of ceramics, but there are great limitations in repairing gaps in ceramics, especially for large-scale gaps, it is necessary to repair both the mud base material and the surface glaze , It is more difficult to repair; at the same time, d...
