Embodiment 1

[0020] An environmentally friendly treatment method for waste cutting fluid without discharge, which is characterized in that it includes the following steps: (1) performing physical and chemical detection on the waste cutting fluid to determine what type of waste cutting fluid it is, and waste cutting fluid according to its appearance and physical and chemical indicators are divided into three categories, namely waste liquid produced by emulsified oil, waste liquid produced by microemulsion cutting fluid and waste liquid produced by fully synthetic cutting fluid; (2) according to the type of waste liquid and physical and chemical indicators, adding cutting fluid Waste liquid discharge-free regeneration environmental protection treatment additive, the addition of the regeneration treatment additive is 1-10% of the weight of the waste liquid, stir evenly at room temperature to obtain the regenerated cutting fluid; (3) test the regenerated cutting fluid according to national or in...

Embodiment 2

[0022] If the cutting fluid waste liquid is the waste liquid produced by emulsified oil, the cutting fluid waste liquid discharge-free regeneration environmental protection treatment additive A is added. The regeneration treatment additive A includes the following raw materials in parts by weight: 0.1 part of antirust agent, 3 parts of nonferrous metal corrosion inhibitor, 0.1 part of lubricant, 10 parts of tall oil or oleic acid, 0.1 part of surfactant, emulsifier 20 parts, 0.1 part of coupling agent, 10 parts of co-solvent, 0.1 part of defoamer, 10 parts of alkaline retaining agent, 0.1 part of chelating agent, and 2 parts of fungicide.

[0023] If the cutting fluid waste is the waste liquid produced by the microemulsion cutting fluid, the waste cutting fluid waste discharge-free regeneration environmental protection treatment additive B is added. The cutting fluid waste liquid discharge-free regeneration environmental protection treatment additive B includes the following r...

Embodiment 3

[0026] If the cutting fluid waste liquid is the waste liquid produced by emulsified oil, the cutting fluid waste liquid discharge-free regeneration environmental protection treatment additive A is added. The regeneration treatment additive A includes the following raw materials in parts by weight: 10 parts of antirust agent, 0.1 part of nonferrous metal corrosion inhibitor, 5 parts of lubricant, 0.1 part of tall oil or oleic acid, 5 parts of surfactant, emulsifier 0.1 part, 10 parts of coupling agent, 0.1 part of co-solvent, 2 parts of defoamer, 0.1 part of alkaline retaining agent, 5 parts of chelating agent, and 1 part of fungicide.

[0027] If the cutting fluid waste is the waste liquid produced by the microemulsion cutting fluid, the waste cutting fluid waste discharge-free regeneration environmental protection treatment additive B is added. The cutting fluid waste liquid discharge-free regeneration environmental protection treatment additive B includes the following raw m...

Abstract

The invention discloses a cutting fluid waste liquid discharge-free regenerative environmental protection treatment additive. A method using the additive comprises (1) carrying out a physical and chemical test on a cutting fluid waste liquid to determine the kind of the cutting fluid waste liquid, wherein the cutting fluid waste liquids are divided into an emulsified oil waste liquid, a microemulsion cutting waste fluid and a fully synthetic cutting waste liquid according to the appearance and physicochemical indexes, (2) adding the cutting fluid waste liquid discharge-free regenerative eco-friendly treatment additive according to the type of the waste liquid and physicochemical indexes and carrying out uniform stirring at the normal temperature to obtain a regenerated cutting liquid, and(3) carrying out detection and using the qualified regenerated cutting liquid. Through use of the regenerative eco-friendly treatment additive, the appearance of the cutting liquid is recovered, the lubricating, cleaning and anti-rust performances of the waste liquid are improved, the normal cooling, lubrication, rust removal and cleaning performances are recovered, the waste liquid can be reusedand the treatment effects are good.

Description

technical field [0001] The invention relates to the technical field of cutting fluid waste treatment, in particular to an additive and a method for emission-free regeneration and environmental protection treatment of cutting fluid waste. Background technique [0002] Metal cutting fluids with cooling, lubricating, anti-rust and cleaning functions must be used when metal materials are processed by machine tools. Cutting fluid classification: emulsified oil, microemulsified cutting fluid, fully synthetic cutting fluid. Cutting fluid generally contains 20-100% active components. Cutting fluid is generally diluted 10-30 times with tap water during use. During use, stock solution and water are regularly added to maintain the normal concentration of effective substances and maintain normal physical and chemical indicators. Generally, after 1-6 months of use, the physical and chemical indicators of the working fluid of the cutting fluid deteriorate seriously, and the addition of t...
