A water-based cutting fluid for nuclear power equipment processing and its dilution

Abstract

The present invention discloses a water based cutting fluid for nuclear power equipment processing, and a dilution solution thereof. The water based cutting fluid comprises 3-10% of an anti-rust additive, 2-10% of organic amine, 3-10% of fatty acid amide, 3-10% of long-chain fatty acid, 2-5% of fatty alcohol polyoxyethylene ether, 5-8% of petroleum sodium sulfonate, 1-5% of fatty alcohol and / or aliphatic ether, 10-15% of vegetable oil-based extreme pressure additive, 15-20% of base oil, 1-2% of a sterilization agent, 0.5-1.0% of a defoamer, and 30-45% of water, wherein the anti-rust additive is a boric acid anti-rust additive and dicarboxylic acid. The water based cutting fluid of the present invention has characteristics of good lubricating property, good cooling performance, good rust resistance, good cleaning performance, no chlorine, diamine, nitrite and other nitro compounds, no environmental pollution, no harm on human body, no irritating odor, no corrosion on equipment and processed parts, excellent cleaning performance during the processing process, and effective cutter service life prolonging.

Description

technical field [0001] The invention relates to the field of metal working fluids, in particular to a water-based cutting fluid for nuclear power equipment processing and a dilution thereof. Background technique [0002] With the gradual lack of global energy, in order to respond to energy conservation, environmental protection, and emission reduction, countries around the world are vigorously accelerating the development of clean energy. Traditional thermal power and other high-energy-consuming, high-pollution power generation methods are gradually fading out of the market. Nuclear power is the future international power structure. Adjustment of the main direction of investment will greatly exceed the conventional power plant. [0003] Reactors are the key design of nuclear power plants, where chain fission reactions take place. There are many types of reactors, and pressurized water reactors are the most widely used in nuclear power plants. Different reactor types have d...
