How to improve the efficiency of copper wire drawing liquid?

Copper wire drawing liquid plays a vital role in the copper wire drawing production process of the cable industry. As a wire drawing lubricant, it directly affects production efficiency and product quality. However, many companies fail to use and maintain the wire drawing liquid correctly in actual production, resulting in low production efficiency, unstable product quality, and even production line shutdown, causing direct economic losses to the company. Therefore, improving the efficiency of copper wire drawing liquid is not only a need to optimize the production process, but also the key to enhancing the competitiveness of enterprises.

1. Choose the right copper wire drawing liquid

Choosing high-quality copper wire drawing liquid is the first step to improve the efficiency of use. High-quality wire drawing liquid should have high lubricity, low foaming and good cooling performance. Wire drawing liquid with good lubricity can effectively reduce friction and wear, improve wire drawing speed and quality; low foaming can reduce production interference caused by foam and ensure the smoothness of the production process; good cooling performance can prevent copper wire from overheating and deformation, and ensure product quality.

In addition, the concentration of copper wire drawing liquid also has a direct impact on production efficiency. Too high or too low concentration will affect the wire drawing effect and production stability. Therefore, the concentration of the wire drawing liquid should be regularly tested and adjusted according to the actual production situation to ensure that it is within the optimal range.

2. Strictly control the water quality and use temperature

The quality of water directly affects the performance of the wire drawing liquid. To ensure the best performance of the wire drawing liquid, soft water with a hardness of less than 50PPM, a chloride ion content of no more than 10PPM and no sulfate ions should be used. At the same time, it is also very important to strictly control the use temperature of the wire drawing liquid. Generally speaking, the optimal working temperature of the copper wire drawing liquid is 36℃~45℃. Excessive temperature will cause the effective components in the wire drawing liquid to volatilize and increase the loss, while accelerating lubrication failure and conductor oxidation. Therefore, during the production process, a cooling tower or heat exchanger should be installed to reduce the use temperature of the emulsion.

3. Regularly test and maintain the pH value

The pH value is an important indicator for measuring the pH value of copper wire Drawing Oil. The ideal pH value range should be maintained between 8.2~9.5, that is, to maintain a weak alkaline state. During use, the pH value may drop, affecting the antioxidant properties of the Wire Drawing Oil and its ability to inhibit bacterial growth. Therefore, the pH value of the Drawing Oil should be tested regularly, and the pH value should be controlled within the specified range by using adjusting agents such as triethanolamine and sodium carbonate.

At the same time, the oil concentration and emulsification stability of the Drawing Oil should be tested regularly to ensure stable lubrication performance. The quality of emulsification stability is directly related to the lubrication and cleaning performance of the drawing oil, which can be determined by the standard method and the simple method. When the emulsion shows signs of failure, such as black color and the appearance of colloid, the new liquid should be replaced in time.

4. Strengthen filtration and cleaning work

In order to reduce the probability of copper powder and impurity particles suspended on the surface of the emulsion, resulting in poor cleaning and shutdown, the filtration and cleaning of the emulsion should be strengthened. The oil pool can be divided into three pools: "filtration pool-sedimentation pool-use pool", and stainless steel mesh and non-woven filter cloth are used for filtration to achieve the best cleaning effect. In addition, the drawing liquid should be replaced regularly to maintain its good lubrication and cooling performance.

5. Optimize equipment maintenance and process parameters

Equipment maintenance and process parameter optimization are also important factors in improving the efficiency of copper wire drawing liquid. Ensuring that the equipment runs well and adjusting the appropriate drawing speed and pressure can effectively reduce the consumption of copper drawing liquid and improve production stability and efficiency. At the same time, keeping the temperature and humidity of the working environment within a reasonable range will help the stability and performance of the copper drawing liquid.

In summary, improving the efficiency of copper wire drawing liquid requires selecting appropriate drawing liquid, strictly controlling water quality and use temperature, regularly testing and maintaining pH value, strengthening filtration and cleaning work, and optimizing equipment maintenance and process parameters. Through comprehensive measures, it can ensure that the copper wire drawing liquid plays the best role in the production process, improve wire quality and production efficiency, and bring greater economic benefits to the enterprise.
