Cleaning fluid for cold-rolled high-zinc-copper alloy pipes

Abstract

The invention relates to a cleaning solution for high-zinc copper alloy cold-rolled pipes. The cleaning solution is prepared from the following components in percentage by mass: 8-22% of ethylenediamine tetraacetic acid disodium, 10-25% of stearyl dihydroxyethyl amine oxide, 8-25% of polyacrylic acid, 10-20% of sodiumdodecyl benzene sulfonate, 6-15% of sodium metasilicate pentahydrate, 8-12% of cocoanut fatty acid diethanolamide, 5-15% of fatty alcohol-polyoxyethylene ether and the balance of deionized water. The cleaning solution is wide in deoiling and decontamination range, separable from oil contamination and good in cleaning effect; the cleaning solution is capable of removing contaminants such as lubricating oil, metal machining fluid, grinding fluid and the like on the surface of copper and copper alloys; the cleaning solution is high in cleaning capability and high in speed; in addition, the cleaning solution is reusable and pollution-free and has anti-rust capability. The cleaning solution is capable of quickly removing the contaminants on the surface of the copper alloys without corrosion to the copper alloys, and therefore, the cleaned copper alloys are smooth and bright in surface; the cleaning efficacy is greater than 99%, and a remarkable effect is achieved.

Description

technical field [0001] The invention relates to a cleaning solution for cold-rolled high-zinc-copper alloy pipes, belonging to the technical field of cleaning copper alloy pipes. Background technique [0002] In the process of copper alloy tube processing, a large amount of lubricating oil is used. The lubricating oil has good adhesion and lubricity, which can effectively reduce the friction during the drawing process and ensure the quality of the copper alloy tube surface. Processed copper alloy tubes are mainly used in heat exchangers and sanitary ware, especially for nuclear power heat exchangers, which have extremely high requirements for residual carbon film and other substances on the surface of copper alloy tubes, based on the performance requirements of copper alloy tubes during use , The surface of the processed copper alloy tube must be cleaned to achieve a high degree of cleanliness. Therefore, the processed copper alloy pipe must be cleaned. According to the cle...

Problems solved by technology

Existing cleaning agents for metal copper materials are mostly solvent-based, such as kerosene as the main raw material of commonly used cleaning agents, the cleaning power and volatilization speed of kerosene are difficult to meet the needs of the current use of copper alloy pipes

The disadvantages of these cleaning agents are that the cleaning time is longer, and the metal copper material after cleaning is prone to black surface layer, which brings trouble to subsequent processing, especially affects the processing of precision components, and the cleaning agent is also more corrosive to equipment. Strong, increase equipment cost, cleaning effect is not ideal
