Calcium multi-purpose grease is a type of lubricant formulated from a mixture of calcium soap, mineral oil, and other additives that enhance its properties. It is known for its water resistance and good mechanical stability, making it suitable for various applications across different industries.
Various additives are included to enhance properties such as oxidation resistance, corrosion inhibition, and pressure handling capabilities. Common additives include antioxidants, corrosion inhibitors, and extreme pressure agents.
It is highly resistant to water, which prevents it from being washed out in wet conditions and protects metal surfaces from corrosion and rust.
It maintains its structural integrity and performance within a moderate temperature range, typically up to about 60°C (140°F).
It resists being broken down or sheared under mechanical stress, maintaining its consistency and effectiveness over time.
This grease exhibits good adhesion to metal surfaces, ensuring a continuous protective film that reduces wear and tear.
Calcium multi-purpose grease typically includes additives designed to enhance its ability to withstand high-pressure conditions. These additives, often referred to as extreme pressure (EP) agents, include compounds such as phosphorus or sulfur-based chemicals, which form a layer on the metal surfaces to prevent direct metal-to-metal contact, thus reducing wear and tear under high loads. However, it is important to note that while calcium grease can handle moderate pressure conditions well, it may not be suitable for extremely high-pressure situations compared to other greases like lithium or lithium complex greases, which are often used in higher pressure applications.
Calcium multi-purpose grease is effective within a temperature range of -10°C to 60°C (14°F to 140°F). Below -10°C, it becomes stiff, increasing friction and wear in machinery. Above 60°C, it may soften excessively and degrade faster due to increased oxidation. While suitable for general industrial use, it’s less ideal for extreme conditions without modifications or alternative lubrication strategies.
