Abstract

A composition for surface cleaning of a platinum-osmium alloy comprises the following ingredients by weight: 10-30 parts of dihydroxymethyl benzoic acid, 30-50 parts of diethylene glycol dimethyl ether, 5-10 parts of N-methyl pyrrolidone, 50-70 parts of aluminum silicate, 20-30 parts of sodium dodecyl sulfonate, 30-40 parts of 2-ethyl hexanol, 20-30 parts of dimethyl imidazole, 5-10 parts of a surface active agent and 100-200 parts of ionic liquid. Compared with the conventional cleaning agent, the composition for surface cleaning of the platinum-osmium alloy, provided by the invention, has a good cleaning effect on grease, ensures that the residual quantity of a solvent is lower than the conventional technical standard, doesn't produce poisonous and volatile ingredients, and cannot react with metal.

Description

[0001] technical field [0002] The invention belongs to the technical field of metal material cleaning, in particular to a composition for cleaning the surface of platinum-osmium alloy. [0003] Background technique [0004] Commonly used chemical cleaning agents can be classified in different ways. For example, according to its chemical composition, it can be divided into inorganic chemical cleaning agents and organic chemical cleaning agents; some cleaning agents may have different effects on different dirt, or have two or more effects on the same dirt, then They should be classified according to their main function under normal circumstances. The classification of cleaning agents is often classified according to the material: aluminum parts cleaning agent, steel cleaning agent, copper cleaning agent, plastic cleaning agent. Water and non-aqueous solvents: Dirt solvents refer to substances that can remove the dirt of the cleaning object in a dissolved or dispersed form...
