At the factory, a colleague prepares to expose the waste cutting fluid to reduce the moisture conten

It is an industrial liquid used in the process of metal cutting and grinding to cool and lubricate tools and processed parts, and the cutting fluid is made of a variety of super functional additives through scientific compounding, and has good cooling performance, lubrication performance, anti-rust performance, degreasing and cleaning function, anti-corrosion function, and easy dilution characteristics. It overcomes the problems that the traditional soap-based emulsion is easy to smell in summer, difficult to dilute in winter, and has poor anti-rust effect, and has no adverse effect on lathe paint, and is suitable for cutting and grinding of ferrous metals, which is a relatively advanced grinding product at present. The cutting fluid is better than the saponified oil, it has the characteristics of good cooling, cleaning, rust prevention, etc., and has the characteristics of non-toxic, tasteless, no erosion of the human body, no corrosion of equipment, and no pollution to the environment.

It is feasible to remove water by basking in the sun, but it is not recommended to expose to the sun.

No, waste cutting fluid is hazardous waste (900-06-06) and must be managed as hazardous waste and must not be discharged.

Fully Synthetic Water-Soluble Wire Cutting Fluid Formulation What is the difference between water-soluble wire cutting fluid and water-based baseline cutting fluid? There is some confusion about the concept of "water-based" working fluids, especially when it is often confused with aqueous all-synthetic cutting fluids (or water-soluble wire cutting fluids) with semi-synthetic fluids (which are actually suspensions). Below, Yixing Huaqing Lubricating Material Technology **** will learn with you the varieties and differences of wire cutting fluid.

Metal cutting fluids (including EDM fluids) are divided into four categories: 1 pure oil type, 2 emulsified type, and 3 semi-synthetic type (micro emulsion type, synthetic type, four categories) according to the different states existing in the composition and use of the product. Pure oil type:

Composed entirely of mineral oil and oil-soluble substances; When using, it can be added directly and cannot be mixed with water. Products such as: extreme pressure cutting oil, EDM fluid, etc.

Emulsified type: composed of mineral oil, emulsifier and necessary additives, with a mineral oil content of not less than 60%; When used, dilute with water to a 5% suspension. Products such as:

Anti-rust emulsified oil, DX-wire cutting fluid, saponification liquid, saponification block, emulsion paste, etc. Semi-synthetic pre-sodium type: composed of emulsifier, mineral oil, water-soluble rust inhibitor, etc., with a mineral oil content of about 15 30%; When used with a suspension diluted to 5% 8% with water.

Products such as: micro-emulsion cutting liquid, some "water baseline cutting fluid", etc. Synthetic:

It is composed entirely of water-soluble substances, and is diluted to a 5% 25% aqueous solution when used with water. Products such as: synthetic cutting fluid, water-soluble wire cutting fluid, internal circle slicing fluid, etc.

Emulsified type, semi-synthetic type (microemulsion type), and synthetic type are used with 75 to 95% water, and water accounts for most of the base.

There are two kinds of cutting fluids, one is water-based cutting fluid and the other is oil-based cutting fluid, so the treatment method is also different.

To test the composition of the waste liquid cutting fluid, if the active ingredients (fatty acids, rust inhibitors, defoamers, surfactants, etc.) still exist, it is recommended to remove oil and particles by physical means, so that the cutting fluid can also be recycled and reused, turning waste into treasure, and the physical technology of Luhong hydraulic cavitation is recommended. If the active ingredient has been lost, it is recommended to do direct treatment, in addition to the biochemical method of building a sewage treatment station, you can also use low-temperature distillation or membrane treatment technology.

This has a great relationship with the original cutting fluid itself, cutting fluid in the production of nothing more than water, base oil, surfactant, rust inhibitor, defoamer, fungicide, etc., due to the immiscible oil and water, the use of some surfactant hydrophilic and lipophilic groups, the formation of translucent colloid. The water is emulsified to a white color. As the cutting fluid component is consumed by use in the lathe, some of it is also brought in.
