Problems solved by technology

Surface coating can keep the surface of silverware as bright as new, but its disadvantages are also obvious. For example, the coating film needs to reach a certain thickness, which will affect the natural metallic texture of the silverware surface; the coating film must be uniform and smooth, requiring high construction technology and difficult to master; It is not easy to repair and remove after the coating film is discolored or damaged, which affects the appearance of silverware

Abstract

The invention discloses a brightness-retaining agent for silverware and belongs to the technical field of silverware maintenance. The brightness-retaining agent is used for solving the problem that the surface of the silverware is easily oxidized, vulcanized and discolored. The brightness-retaining agent is prepared from the following components in parts by weight: 5-10 parts of sodium hypophosphite or sodium phosphite, 1-5 parts of coconut oil fatty acid diethanolamide, 1-3 parts of deionized water, 1-2 parts of Tween-20, 1-3 parts of potassium dihydrogen phosphate, 1-3 parts of sodium dihydrogen phosphate, 3-5 parts of sodium carbonate, 1-3 parts of methyl benzotriazole, 1-3 parts of 2-mercaptobenzothiazole thiadiazole, 1-2 parts of sodium lauryl sulfate and 0.5-1 part of sodium stearate. During use, the brightness-retaining agent is dissolved in deionized water to obtain a 5-10% aqueous liquid. The brightness-retaining agent is stably stored, is convenient to operate and is free of potential safety hazard and the surface texture of the silverware is not affected.

Description

technical field [0001] The invention relates to a powder used for silverware maintenance, in particular to a powder used for keeping silverware bright after removing surface silver sulfide or silver oxide and other staining substances on the silverware. Background technique [0002] After the silverware is in contact with the air or human sweat for a long time, black spots or yellow spots will appear on the surface. The main component of this black or yellow stain is silver sulfide, and there are also small amounts of silver chloride and silver oxide. At present, these stains can be removed by physical or chemical methods, such as grinding and polishing, pickling, chemical reduction or a combination of physical and chemical methods. After the surface stains are removed from the silverware, the newly formed silver surface is prone to defects. Therefore, if the silverware is not properly treated after the surface silver sulfide or silver oxide stains are removed, the silverwa...
