What is soapy water?

Soapy water or soluble oil is known as a water-soluble oil of which there are different types. These types include oily soapy water, nano oily soapy water, synthetic soapy water, and nano soapy water. Soapy water is used in various industries such as metalworking, turning and as a lubricant in various industries.

Soapy water oil is a type of oil that can be mixed with water to form a stable emulsion in the form of a colored candy solution. The exceptional stability of this emulsion and resistance to corrosion and rust are among the advantages of this product.

soapy water (soluble oil)

Oils do not naturally dissolve in water; Instead of being dissolved in water, when oil is added to water, they are suspended in the water as tiny droplets. This process is done using a chemical compound called an emulsifier, which breaks the oil into very fine particles and disperses it in the form of an emulsion in water. The resulting mixture is known as emulsifying oil or soluble oil. This mixture contains a base oil, emulsifier, and other additives such as antibacterial, anticorrosive, antirust, and antifoam.

Emulsions or water-absorbing oils are known as combinations of a base oil and an emulsifier with additives such as antibacterial, anti-corrosive, etc. These materials are used with the ability to emulsify in water and are combined in the form of an emulsion of sweetness with color and homogeneity. Emulsions facilitate metalworking processes by providing optimal lubrication properties and prevent heat generation. These oils have anti-rust and anti-adhesion properties that are suitable for all types of metalworking operations and are used in processes that require a mixture of water and oil.

To reduce the rusting of parts and cutting and turning tools, a greater proportion of oil is added to the oil-water mixture. In machining operations, where both lubrication and cooling are critical, higher concentration emulsions are used. Generally, in processes where cooling is more important, emulsions with lower concentration are used.

Anionic and non-ionic emulsifiers are widely used in these lubricants, while cationic emulsifiers are less used due to their instability in alkaline environment (pH 8-9.5).

The active ingredients in metalworking emulsions, due to the fresh and reactive surfaces created by peeling, can prevent the adhesion of tools and workpieces and provide effective reactions.

Ingredients of soapy water

Approximately 95% of the composition of this mixture is water, about 4% oil, and detergents, along with an emulsifier to create an emulsion between water and oil (in soapy water), an antioxidant to prevent corrosion, an antifoam or antifoam to prevent It consists of product foaming, biocides to prevent bacterial and fungal growth, emulsion stabilizers, and compressible additives.

Features of soapy water

The life cycle list or the list of inputs and outputs of the life cycle, which is called Life Cycle Inventory or LCI, includes collecting data and performing calculations in order to quantify the inputs and outputs of the product life cycle. This process is considered as the heart of the life cycle assessment method. Accurate and complete data collection is critical in this phase of life cycle assessment, as incomplete or missing data can be the biggest challenge in this phase of LCA.

In the life cycle inventory, quantitative and qualitative data are collected for each process that enters the scope of the system. These data may be measured or calculated to quantify the inputs and outputs of a process unit. If data is collected from public sources, their reference should be specified. For data that are important to the study’s conclusions, details about the process of their collection, when the data are collected, and more information about data quality indicators should be noted.

Consequence assessment in life cycle assessment (LCA)

This product has outstanding features such as excellent lubrication and cooling. It quickly mixes with water and forms a stable and homogeneous emulsion. It contains synthetic colloids that prevent the rusting of various parts and equipment and has high resistance to the formation of foam and sediment. It also has excellent filtration capability and does not contain harmful substances such as nitrite, chlorine, ammonium, etc. With long life and good resistance to micro-organisms, it is very easy to use and maintain. This product helps clean shavings and chips, as well as the surfaces of workpieces and cutting tools, and prevents rusting and welding of newly created surfaces by cutting. It is compatible with alkaline additives and has a high resistance to fumes. This product does not foam and has a very good compatibility with hard water. It also has a high resistance to burning and does not need phosphate, ester and fatty acids to create a lubricant. It has the ability to be used in stretching, molding, and pure gluing operations. This soluble oil has high stability and is used as electrical insulation in electrical equipment such as transformers.

Preparing and charging soapy water to the device

Determining the percentage composition of soapy water for each process in machining is done by a technical expert, which depends on the technical specifications of the soapy water and several factors, including the type of machine, the type of process, the coolant, the material of the parts, the hardness of the part, the speed of chipping and other factors. has it.

The characteristics of the water used is also very important as one of the factors affecting the quality of soapy water. Drinking water should have a calcium carbonate hardness of about 175 to 355 ppm (about the same as city water) and a neutral pH. It should also be free of chlorine, nitrite and suspended particles. The chemical composition of the emulsifier in soluble oils is usually mineral. Hard water contains sodium and potassium carbonate and sulfate salts that react with the emulsifier and can cause water and oil to separate.

To prepare the emulsion solution, the ingredients are slowly added to a stirring container of water. The oil must also be completely micronized so that it can be homogeneously distributed among the water molecules, which is best homogenized using a mixer.

After preparation, the emulsion solution is poured into the tank of the device. The amount of soapy water used for each device is calculated based on the machining process and the time required for the soapy water to cool down in the tank and settle the colloids in it.

Benefits of using soapy water

Using high-quality soapy water increases the life of the device and reduces the costs of repairs. Also, it leads to reduction or elimination of wastewater discharge costs and environmental protection. Soapy water is used as a coolant and soapy water oil can act as a coolant to reduce frictional heat. Also, as a lubricant, it can reduce friction and improve the performance of parts.

How Z1 oil works and how it works for radiators

One of the basic uses of soapy water in various industries is as an oil cooler. Soapy water is also used as a soluble oil for radiators. In this process, soluble oils are used to remove the excess heat emitted from internal combustion engines. The heat of the engine is transferred to a device called an oil cooler through a heat exchanger. The operation of the oil cooler, which is adjusted based on the oil circulation, works similarly to the radiator. Also, during engine operation, oil viscosity decreases with increasing temperature and due to this decrease, optimal lubrication performance may be affected. Therefore, it is necessary to use an oil cooler to cool the oil and maintain its proper viscosity during engine operation.
