Problems solved by technology

First, the biodegradability is poor. After testing, its BOD (biological oxygen demand) / COD (chemical oxygen demand) is generally around 0.2, which makes the waste liquid difficult to handle and seriously pollutes the environment; second, the formula contains nitrous acid Sodium and other toxic and harmful substances endanger human health

Abstract

The invention discloses biodegradable hard water-resistant water-soluble metalworking liquid. The biodegradable hard water-resistant water-soluble metalworking liquid consists of organic acid, organic amine, corrosion inhibitor, synthetic lubricant, surfactant, water and defoamer. The biodegradable hard water-resistant water-soluble metalworking liquid is high in biodegradability, hard water resistance, lubricity, rust prevention property and corrosion resistance and long in service life and is friendly to people and environment.

Description

technical field [0001] The invention relates to a biodegradable hard water-resistant water-soluble cutting fluid. Background technique [0002] In order to adapt to the rapid development of my country's mechanical processing industry and better meet the requirements of users, in the past ten years, the water-soluble cutting fluid products used in metal processing produced by domestic manufacturers not only have lubricating performance, anti-rust and anti-corrosion performance, cycle life, etc. The performance index has been significantly improved; and the hard water-resistant water-soluble cutting fluid product developed in combination with national conditions, when used under the condition of 7000mg / l hardness water quality, there is no oil separation or soap separation phenomenon, but due to various reasons such as technology, technology, and understanding At present, there are still two major drawbacks in the hard water-resistant water-soluble cutting fluid products produce...
