What are the ingredients of copper wire drawing liquid?

In the field of metal processing, Copper Wire drawing liquid plays a vital role. It can not only provide necessary lubrication and cooling for the copper wire drawing process, but also effectively prevent oxidation of the copper wire surface, improving product quality and production efficiency. However, in order to fully exert these functions, the ingredients of the Drawing Fluid must be carefully designed and proportioned. This article will deeply explore the components of copper wire drawing liquid and analyze the functions of various components, with a view to providing valuable reference for relevant practitioners.

1. Basic components of copper wire drawing liquid

Copper wire drawing fluid is a lubricant specially designed for copper wire and steel wire drawing. Its composition is relatively complex, but it can be roughly divided into the following categories:

Lubricant

Lubricant is the core component of wire drawing fluid. It can significantly reduce the friction coefficient between metals and reduce heat, friction and wear. During the copper wire drawing process, the lubricant can form a uniform lubrication layer on the surface of the copper wire and steel wire, thereby ensuring the stability and continuity of the drawing process. Common lubricants include triethanolamine oleate, sodium petroleum sulfonate, etc.

emulsifier

The main function of emulsifier is to mix lubricant, water and other additives evenly to form a stable emulsion. The presence of emulsifier makes the drawing liquid have better dispersion and fluidity, thus improving the lubrication effect. At the same time, the emulsifier can also prevent the drawing liquid from delaminating or settling during use, maintaining its stability and durability.

preservative

During the production, storage and use of wire drawing fluid, due to contact with air, moisture and metal surfaces, they are easily contaminated, resulting in oxidation, corrosion and other problems on the surface of copper wires and steel wires. Therefore, preservatives need to be added to the drawing fluid to prevent these phenomena from occurring. Preservatives inhibit the growth and reproduction of bacteria, thereby extending the service life of the drawing fluid.

surfactant

Surfactants are chemicals that reduce the surface tension of liquids. In the drawing fluid, surfactants can make the lubricant better coated on the surface of the copper wire and steel wire, thereby ensuring the stability of the lubrication state and the consistency of the drawing effect. At the same time, surfactants can also improve the fluidity and dispersion of the drawing fluid, making it easier to use and maintain.

Other additives

In addition to the above main ingredients, the drawing liquid may also contain a variety of other additives, such as defoaming agents, antioxidants, anti-rust agents, etc. The presence of these additives can further enhance the performance of the drawing fluid and meet different processing needs.

2. Analysis of specific ingredients and functions

engine oil

Engine oil is an important lubricant in drawing fluid, which can provide necessary lubrication and cooling effects. The addition of engine oil makes the drawing fluid have better wear resistance and extreme pressure properties, thereby improving the stability and efficiency of the drawing process.

Triethanolamine oleate

Triethanolamine oleate is a commonly used lubricant ingredient with good lubricity and dispersion. In the drawing fluid, triethanolamine oleate can form a uniform lubricating film to prevent direct contact and friction between metals.

Sodium petroleum sulfonate

Sodium petroleum sulfonate is an efficient emulsifier ingredient that can mix engine oil, water and other additives evenly to form a stable emulsion. The presence of sodium petroleum sulfonate makes the drawing liquid have better fluidity and dispersion, thus improving the lubrication effect.

Sulfurized oil

Vulcanized oil is an additive with anti-rust function, which can inhibit oxidation and corrosion of metal surfaces. In the drawing fluid, the vulcanized oil can form a protective film to prevent the surface of the copper wire and steel wire from being polluted and damaged.

Silicone

Silicone is a high-performance lubricant ingredient that provides excellent lubrication and anti-wear properties. In the drawing fluid, silicone can reduce friction and wear between metals and extend the service life of the mold.

phenyltriazole

Phenyltriazole is a commonly used rust inhibitor ingredient that can effectively prevent oxidation and corrosion of metal surfaces. In the drawing fluid, phenyltriazole can form a dense protective film to protect copper wires and steel wires from contamination and damage.

water soluble rust inhibitor

Water-soluble anti-rust agent is an environmentally friendly anti-rust agent component that can be mixed evenly with water to form a stable anti-rust liquid. In the drawing fluid, water-soluble rust inhibitors can provide long-lasting anti-rust effects and ensure the surface quality of copper wires and steel wires.

3. Summary

To sum up, the components of copper wire drawing liquid are relatively complex, but each component plays a vital role. The synergistic effect of lubricants, emulsifiers, preservatives, surfactants and other additives gives the drawing fluid excellent lubrication, cooling, anti-rust and antioxidant properties. Therefore, when selecting and using drawing fluid, appropriate drawing fluid components and ratios should be selected according to specific processing needs and process conditions to ensure the stability of the processing process and the consistency of product quality. At the same time, attention should also be paid to the maintenance and management of the drawing fluid, regular testing of its performance indicators, and timely replacement and replenishment of the drawing fluid to extend its service life and improve processing efficiency.
