Description
Technical field
The present invention relates to a kind of pulvis for silverware maintenance, especially a kind of after silverware removes surface sulfide silver or silver suboxide isochrome plaque substance, for keeping the pulvis of silverware light.
Background technology
After silverware contacts with air or human sweat for a long time, its surface can produce blackspot or macula lutea.The color spot main component of this black or yellow is silver sulfide, also there is the compositions such as a small amount of silver chloride and silver suboxide simultaneously.At present, removing these color spots can by physics or chemical process, and as sanding and polishing, pickling, chemical reduction or physico-chemical processes combine process etc.After silverware removes surperficial color spot, newly-generated silver surface easily produces defect, and thus silverware is after removing surface sulfide silver or silver suboxide color spot as without suitable process, and the silverware of recovery light is easy to again be oxidized and blackening turns yellow.
The measure that current prevention silverware again be oxidized has:
Silver surface Passivation Treatment, comprises chemical passivation and electrochemical passivation.Chemical passivation often adopts oxygenant to form fine and close passive film to stop the contact of silver and sulphur or oxygen at silver surface, and compound corrosion inhibitor reaches the object keeping silver light simultaneously.Oxygenant adopts potassium bichromate or hydrogen peroxide etc., and inhibiter adopts benzotriazole, mercaptobenzothiazole etc., can be made into aqua or paste use.Its major defect is that partial oxidation agent is poisonous, as potassium bichromate; Oxygenant is unstable, and especially oxygenant and inhibiter are mixed with aqua, and the quality guaranteed period only has 3-6 month.Electrochemical passivation requires electrolysis or electroplating device, coordinates the Anti-tarnishing effect that suitable electrolytic passivation liquid and passivation technology just can reach good.Operate more loaded down with trivial details, influence factor is many, and also adds the materials such as potassium bichromate in partial electrolyte passivating solution, there is safety and environmental risk.
Silver surface coating processing, coating comprises the filmogens such as mineral oil, wax, resin, the object that compound corrosion inhibitor reaches isolation from oxygen simultaneously, sulphur keeps silver light.Filmogen comprises acrylic resin, urethane resin, epoxy resin etc., and auxiliary film forming matter is as oleic acid, stearic acid etc., and inhibiter is as vulkacit H, 1-phenyl-5-mercapto tetrazole etc.Surface-coated can keep silverware surface-brightening as newly, but its shortcoming is also obvious, as film need reach certain thickness, affects silverware surface naturally metal-like; Film wants uniform ground, and construction process requirement is high, not easily grasps; Not easily repair and remove after film variable color or breakage, affect silverware attractive in appearance.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of safety non-toxic, and component is stablized, convenient storage and transport, easy to operate, does not affect the silverware light retention agent of silverware surface tactile sensation.
