Problems solved by technology

At present, most of the degreasing agent products on the market are corrosive to copper alloy pipes, and long-term use will affect the appearance quality of copper alloy pipes
[0003] In addition, traditional degreasing agents are mostly high-foaming surfactant combinations. While obtaining a good decontamination effect, the surfactant components are often adsorbed on the surface of the copper alloy tube. Therefore, after working for a period of time, the emulsification in the bath The emulsifying agent will gradually lose its emulsifying properties, and the emulsified oil will gradually accumulate in the bath, but it will be adsorbed to the surface of the copper alloy tube that is subsequently put into it, reducing the decontamination effect
[0004] These degreasing agents in the prior art also have problems such as high production cost, poor degreasing efficiency, and serious environmental pollution, which seriously affect the popularization and use of degreasing agent products.

Abstract

The invention relates to a degreasing agent for copper alloy tubes. The degreasing agent is composed of the following components in parts by mass: 10-25 parts of potassium pyrophosphate, 12-24 parts of sodium tripolyphosphate, 8-20 parts of alkylphenol ethoxylates, 20-40 parts of benzotriazole, 10-18 parts of anhydrous sodium metasilicate, and 100-240 parts of water. The degreasing agent for copper alloy tubes disclosed by the invention has an extremely strong cleaning force, and the cleaning force (4%, 70 DEG C) experimentally is over 99%; and the degreasing agent is poor in corrosivity, the corrosivity to the appearance of a copper alloy in a corrosion test is level zero, and the corrosion quantity of the copper alloy is 0.5mg. The degreasing agent is not only high in degreasing efficiency, good in corrosion inhibition and low in production cost, but also long in effect time, simple in operation and easy to operate, therefore, the degreasing agent has a broad application prospect.

Description

technical field [0001] The invention relates to a copper alloy tube degreasing agent, which belongs to the technical field of copper alloy tube degreasing. Background technique [0002] In the process of production and processing, the surface of the copper alloy tube will inevitably be polluted. The outer surface of the copper alloy tube is often covered with grease, oily dirt, etc. It is necessary to use a degreasing agent to remove the oil on the surface of the copper alloy tube. At present, most of the degreasing agent products on the market are corrosive to copper alloy pipes, and long-term use will affect the appearance quality of copper alloy pipes. [0003] In addition, traditional degreasing agents are mostly high-foaming surfactant combinations. While obtaining a good decontamination effect, the surfactant components are often adsorbed on the surface of the copper alloy tube. Therefore, after working for a period of time, the emulsification in the bath The emulsify...
