Metalworking fluid is a coolant and lubricant used in metalworking processes. Its main role is to help the metal processing process be more efficient, precise and safe. In order to achieve these purposes, some additives are usually added to metal working fluids. This article will introduce common additives in metalworking fluids and their functions.
The role of additives in metal working fluids mainly has two aspects. First of all, additives can improve the stability of metal working fluids, making them less likely to change during processing, thereby ensuring the smooth progress of the processing process. Secondly, additives can reduce the corrosiveness of metal working fluids and avoid corrosion damage to metal parts.
The main categories of metal working fluid additives are as follows:
Corrosion inhibitors: Corrosion inhibitors are one of the most important additives in metalworking fluids. Its main function is to inhibit the corrosion reaction on the metal surface, thereby reducing the corrosion rate of the metal. Commonly used corrosion inhibitors include organic amines, imidazolines, acetylenic alcohols, etc.
Abrasives: The main function of abrasives is to improve the grinding efficiency of metal working fluids and help remove dirt and oxide layers on metal surfaces. Commonly used abrasives include alumina, silicon oxide, silicon carbide, etc.
Extreme pressure agent: Extreme pressure agent can reduce the friction coefficient of metal working fluid under high pressure and high temperature conditions, improve processing efficiency, and can also prevent sintering and sticking during processing. Commonly used extreme pressure agents include compounds of elements such as sulfur, phosphorus, and chlorine.
Antioxidants: Antioxidants slow down the oxidation reaction of metalworking fluids, thereby extending their service life. Commonly used antioxidants include phenols, amines, etc.
Antimicrobial agents: Antimicrobial agents prevent the growth of bacteria and mold in metalworking fluids, thereby avoiding contamination and deterioration during processing. Commonly used antibacterial agents include organic acids, alcohols, etc.
When using metalworking fluid additives, you need to pay attention to the following matters:
Appropriate additives should be selected according to processing needs and added according to the instructions for use.
Avoid using additives under high temperatures and direct sunlight to avoid deterioration in performance.
Regularly check the content of additives in metal working fluids and replenish consumed ingredients in a timely manner.
When replacing or adjusting metal working fluid, the original working fluid should be thoroughly cleaned to avoid residues from affecting the new working fluid.
Additives should be stored and used according to instructions to avoid accidental injury or property damage caused by mishandling.
In short, metal working fluid additives are of great significance for improving processing efficiency, reducing corrosion damage and extending the service life of working fluids. In actual use, appropriate additives should be selected based on specific needs, and added and stored in accordance with regulations. Through the correct use of additives, the quality and efficiency of metal processing can be further improved, providing a strong guarantee for the development of industrial production.
Additives for metal working fluids: types and functions
Metalworking fluids play a vital role in industrial production, especially in metal cutting, grinding, rolling and other processes. In order to improve the performance of metal working fluids, the use of additives has become particularly important. These additives can not only improve the lubricity and cooling properties of metal working fluids, but also improve the processing quality and production efficiency of workpieces.
These additives for metal working fluids serve various functions, including lubrication, cooling, corrosion protection,Extreme Pressure (EP) and Anti-Wear Additives, ETC.
