Problems solved by technology
[0003] Copper alloys are widely used in electronics, military, aerospace and other fields, but it is quite difficult to clean the copper surface, because copper alloys are easy to corrode with zinc, tin and nickel elements under the action of cleaning agents to produce galvanic cells The surface of copper alloy, so it is necessary to study an efficient and low-corrosion cleaning agent

Abstract
The invention relates to a copper alloy cleaning agent. The cleaning agent comprises alkaline substances, a surface active agent, a cleaning assistant, a corrosion inhibitor, an environmental-friendly solvent and water, wherein the surface active agent is polyether polyol. The cleaning agent has the good cleaning effect and low corrosivity to a copper alloy.
Description
technical field [0001] The invention belongs to the technical field of cleaning agents, in particular to a copper alloy cleaning agent. Background technique [0002] Copper is a heavy non-ferrous metal, and the output of copper in the world is second only to steel and aluminum. Copper and its alloys are one of the earliest and most widely used metal materials used by humans. Copper has good electrical and thermal conductivity, corrosion resistance, excellent plasticity, and can be welded or processed by hot and cold pressure. Pure copper has low strength and is not suitable for direct use as a structural material. Alloying elements are often added to improve its performance. According to the surface color of copper alloy, copper alloy is divided into three categories: brass, bronze and white copper. Brass is a copper alloy with zinc as the main element and it turns yellow after adding zinc, so it is called brass. According to the types of other elements contained in bras...
