Problems solved by technology

The original hot repair method is to cover the defect with glaze, and then return the whole sanitary ware to the furnace for firing, so that the repaired glaze is completely integrated with the original glaze. Compared with the cold repair method, the hot repair method The repair effect is good, and the visual effect is good, and no defects can be seen, but the hot repair method needs to be returned to the furnace for refiring, and refiring requires energy and time. Therefore, it takes a long time, low efficiency and high cost

Embodiment 3

[0029] 1. Grinding: use a grinder to grind the defective parts on the surface of the sanitary ware, and the distance between the outer edge of the polished area and the outer edge of the defective part of the sanitary ware is 0.3cm;

[0030] 2. Glaze repair: Take a diaphragm with waterproof effect, cut a through hole in the center of the diaphragm, the shape and area of ​​the through hole are consistent with the shape and area that need to be polished at the defect, and the edge of the through hole of the diaphragm is consistent with the periphery of the diaphragm. The distance between the edges is 1.4cm. Cover the defect of the sanitary ware with the diaphragm, and then apply the glaze on the defect of the sanitary ware. The distance between the outer edge of the glaze area and the outer edge of the defect of the sanitary ware is 0.1cm; The components of the material and their mass parts ratio are: 55 parts of polyvinyl acetal, 55 parts of polyacetal resin, 30 parts of ABS res...

Abstract

The invention discloses a spraying-repairing method for ceramic sanitary ware glaze. The spraying-repairing method comprises the following operation steps: polishing: using a polisher to polish a sanitary ware surface with a defect, wherein the distance between the outer edge of the polished surface and the outer edge at the defect of sanitary ware is 0.2-0.5; supplementing glaze: coating the defect of the sanitary ware with glaze, wherein the distance between the outer edge of the coated glaze surface and the outer edge at the defect of sanitary ware is 0.1-0.2 cm; polishing: polishing through the polisher after the glaze supplemented in the step 2 is dried, wherein the polishing area is the same as that in the step I; spraying paint: spraying paint material on the glaze surface polished in the step III by a spraying gun, wherein the paint spraying area is larger than the area after being supplemented with glaze so as to cover the area after being supplemented with glaze. The spraying-repairing method for ceramic sanitary ware glaze, provided by the invention, is simple to operate, low in cost, high in efficiency, and good in repairing effect, saves energy and reduces resource consumption.

Description

technical field [0001] The invention belongs to the field of ceramic processing, and in particular relates to a gunning method for repairing defects on the glaze surface of ceramic sanitary ware. Background technique [0002] Sanitary ware refers to ceramic and hardware household equipment used in bathrooms and kitchens. Sanitary ware is mainly made of ceramics, glass fiber reinforced plastics, plastics, artificial marble (agate), stainless steel and other materials. Compared with other types of sanitary ware, ceramic sanitary ware is more widely used than other types of sanitary ware due to its advantages such as white texture, soft color, compact structure, high strength, and good thermal stability. Common ceramic sanitary ware include: toilets, face washers, sinks, etc. The glaze applied on ceramics is generally made of quartz, feldspar, and clay. After grinding and adding water, it is coated on the surface of the green body and melted by roasting at a certain temperatu...
