Copper alloy low-temperature cleaning agent

Abstract

The invention relates to a copper alloy low-temperature cleaning agent which consists of the following raw materials in percent by weight: 6-8 percent of organic acids, 30-35 percent of surfactant, 0.7 percent of preservative and the balance of water, wherein the organic acids are citric acid and oleic acid; the surfactant comprises an anionic surfactant and a nonionic surfactant. According to the cleaning agent, multiple specified anionic surfactants and nonionic surfactants, organic acids and preservatives are compounded, the corresponding ratio is adjusted, and the mixed cleaning agent has the characteristic of low-temperature cleaning effect and is particularly suitable for cleaning a watch shell. Because parts of a watch are high in precision requirements and are generally made of the copper alloy, the copper alloy has the requirement of having a relatively good cleaning effect at the relatively low temperature of less than 45 DEG C on the temperature or the temperature of cleanout fluid, if the temperature is extremely high, the parts easily discolor or are easily corroded, and therefore, the low-temperature cleaning agent is needed.

Description

technical field [0001] The invention belongs to the field of cleaning agents and relates to cleaning agents for watch casings, in particular to a low-temperature cleaning agent for copper alloys. Background technique [0002] In recent years, with the rapid development of the national economy, the chemical cleaning technology has developed greatly. It has developed from a single hydrochloric acid plus corrosion inhibitor cleaning agent to a variety of different cleaning agents for scales and corrosion products of different materials. agents, such as hydrofluoric acid, EDTA, etc., but each of the existing cleaning agents has one or another shortcoming and limitation, such as hydrochloric acid used as a cleaning agent to corrode equipment, and hydrofluoric acid used as a cleaning agent to pollute the environment. EDTA is used as a cleaning agent, which is expensive and expensive. [0003] According to the search, the following patent documents related to the present applicati...
