Abstract

Belonging to the field of ceramic production, the invention in particular relates to a recycled glaze for ceramic repair and a repair method. The recycled glaze for ceramic repair is composed of sediment, surface mud and cover glaze or is composed of surface mud and cover glaze or only comprises cover glaze. The raw materials for making sediment comprise, by mass, 17-23 parts of glaze powder, 8-12 parts of kyanite powder, 62-68 parts of porcelain powder, and 3-7 parts of zirconium silicate powder. The raw materials for making surface mud comprise, by mass, 72-78 parts of glaze powder, 20-26 parts of frit powder, and 1-3 parts of mullite powder. The raw materials for making cover glaze comprise: 93-97 parts of glaze powder, and 3-7 parts of frit powder. The recycled glaze repair method consists of: employing sediment and surface mud to perform preliminary filling to a height that is 0.05mm-0.1mm higher than the surrounding glaze surface, when the surface of the surface mud becomes smooth, using a spray gun to spray cover glaze till flush with the surrounding surface. The recycled glaze and the method provided by the invention can repair a defect with an area larger than 4 square millimeters and a gap depth larger than the glaze layer thickness, and can repair part of washable surface cracks, bubbles, thin glaze and other defects.

Description

technical field [0001] The invention belongs to the field of ceramic production, in particular to a burn-back glaze for ceramic repair and a repair method. Background technique [0002] The purpose of ceramic repair is to increase the qualified rate of products and reduce defective products. In the existing ceramic repair technology, only defects with an area of ​​less than 4 square millimeters and a gap depth lower than the thickness of the glaze layer can be repaired. The repaired surface often has white spots and pit defects. impact on workers' health and the environment. Contents of the invention [0003] In view of the above problems, the present invention proposes a burn-back glaze and a repair method for ceramic repair, which can repair defects whose area is greater than 4 square millimeters and the depth of the gap is greater than the thickness of the glaze layer, and can also repair some cracks, air bubbles, and thin glazes on the cleaned surface. and other defe...
