What are the hazards of cutting fluid Precautions for the safe use of cutting fluid

Liannuo SCC638 semi-synthetic water-based cutting fluid is specially designed for aluminum alloy machining, has a good anti-oxidation protection effect on the surface of aluminum alloy, has excellent lubricity and extreme pressure, and is suitable for various processing processes of aluminum alloy, including turning, milling, drilling, grinding, reaming, blind hole through hole tapping, etc. SCC638 semi-synthetic water-based cutting fluid does not contain chlorine, nitrite, phenol and other harmful substances, and is an environmentally friendly water-soluble cutting fluid.

1. First of all, it is necessary to select the correct cutting fluid according to the metal processing needs, materials, environment and equipment. In the case of metal processes, cutting fluids may have an impact on workers, the environment and their workpieces.

2. Designate and arrange employees to monitor the cutting fluid used, do a good job in the testing and registration of each data of the cutting fluid, and take immediate maintenance if problems are found.

3. If you find that the workpiece is rusted, smelly, and equipment leakage occurs in the process of using cutting fluid, please contact the cutting fluid manufacturer immediately and ask the manufacturer to dispatch technicians to approach the corresponding problems.

4. Please do a proper job of the used cutting fluid waste liquid, it is strictly forbidden to discharge it directly into the sewer pipe, which will not only have a serious impact on the surrounding water quality, but also will be punished.

5. The storage of cutting fluid should pay attention to avoid light, heat and moisture, which is the key to avoid the deterioration of cutting fluid.

6. Outdoor storage should be sealed and stored to prevent rainwater from infiltrating and causing bacteria to breed and affect the use effect.

Cutting fluid is BAI according to oil

The composition of DU is divided into two categories: insoluble zhi (oil-based) liquid and water-soluble (water-based DAO) liquid. Water-based plate cutting fluids can be divided into emulsions, half-weight synthetic cutting fluids and fully synthetic cutting fluids. The classification of emulsions, semi-synthetic and fully synthetic usually depends on the type of base oil in the product:

Emulsions are water-soluble cutting fluids that use only mineral oil as the base oil; Semi-synthetic cutting fluids are water-soluble cutting fluids that contain both mineral oil and chemically synthesized base oil; Fully synthetic cutting fluids are water-soluble cutting fluids that use only chemically synthesized base oils (i.e., no mineral oils). Each type of cutting fluid will contain a variety of additives other than base oils: rust inhibitors, non-ferrous corrosion passivators, defoamers, etc.

Some manufacturers will have a classification of microemulsions; It is generally considered to be a category between emulsions and semi-synthetic cutting fluids. The dilution of the emulsion is milky white in appearance; The dilution of semi-synthetic solutions is usually translucent, and some products are milky white; Dilutions of fully synthetic fluids are usually completely clear, like water, or slightly colored.

Cutting fluids

YesA kind of industrial liquid used in the process of metal cutting and grinding to cool and lubricate tools and processed parts, 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, easy dilution characteristics.

The lubrication effect of cutting fluid in the cutting process can reduce the friction between rake face and chip, back tool and machined surface, form part of the lubrication film, thereby reducing the consumption of cutting force, friction and power, reducing the surface temperature and tool wear of the friction part between the tool and the workpiece blank, and improving the cutting performance of the workpiece material. In the grinding process, after adding grinding fluid, the grinding fluid penetrates into the grinding wheel workpiece, abrasive grains and abrasive chips to form a lubricating film, so that the friction between the interfaces is reduced, and the abrasive cutting edge is prevented from wearing and sticking to the chips, thereby reducing the grinding force and friction heat, and improving the durability of the grinding wheel and the surface quality of the workpiece.

Second, the cooling effect

The cooling effect of the cutting fluid is to carry the cutting heat away from the tool and the workpiece through the convection and chemical action between the cutting fluid and the workpiece that is heated by the cutting. So as to effectively reduce the cutting temperature, reduce the deformation of the workpiece and the tool, maintain the hardness of the tool, and improve the machining accuracy and durability of the tool. The cooling properties of cutting fluids are related to their thermal conductivity, specific heat, heat of vaporization and viscosity.

The thermal conductivity and specific heat of water are higher than those of oil, so the cooling performance of water is better than that of oil.

3. Cleaning effect

Cleaning effect in the metal cutting process, the cutting fluid is required to have a good cleaning effect, remove the generated chips, grinding chips, iron powder, oil and sand particles, prevent the contamination of machine tools, workpieces, tools, so that the cutting edge of the tool or grinding wheel remains sharp, will not affect the cutting effect, for oil-based cutting oil, the lower the viscosity, the stronger the cleaning ability, especially the cutting oil containing light components such as kerosene and diesel, the better the permeability and cleaning performance. The water-based cutting fluid containing surfactant has a better cleaning effect, because it can form an adsorption film on the surface to prevent particles and sludge from adhering to the workpiece, tool and grinding wheel, and at the same time, it can penetrate into the interface where particles and sludge adhere, separate it from the interface, and take it away with the cutting fluid to keep the cutting fluid clean.

Fourth, anti-rust effect

Anti-rust effectIn the process of metal cutting, the workpiece should be corroded by contact with corrosive media such as sludge produced by the decomposition or oxidation of cutting fluid components, and the surface of machine tool parts in contact with cutting fluid will also be corroded. In addition, when the workpiece is temporarily stored after processing or during the flow between processes, the cutting fluid is also required to have a certain anti-rust ability to prevent the corrosion of the metal caused by the environmental medium and the residual cutting fluid such as oil sludge. Especially in the humid and rainy season, more attention should be paid to anti-rust measures between processes.

Cutting fluid is a new type of water-based synthetic cutting fluid, which replaces the shortcomings of emulsified oil and microemulsion cutting fluid in cleaning and environmental protection. It is mainly composed of lubricants, cleaning agents, rust inhibitors, fungicides, etc. It has excellent lubrication, cleaning, cooling and anti-rust functions.

It is used for lubrication and cooling of various processing methods such as turning, milling, grinding and drilling of steel.

The hazard is long-term exposure to toxic and harmful substances containing sodium nitrite, which will cause itching red spots, it is recommended to use high-quality cutting fluid, that is, do not choose low-grade products in order to save costs. The so-called great value for money.

First of all, cutting fluid is synthesized by chemicals, which is more or less harmful. There are many main ingredients, emulsifiers, extreme pressure lubricants, rust inhibitors, defoamers, bactericidal and antifungal agents.

There is medicinal treatment, and the cutting fluid is toxic.

There are companies that specialize in the disposal of waste liquids, you can contact them.

I don't quite understand your question ... Do you mean to dispose of discarded cutting fluids?
