Boron Nitride Powder for Industrial Lubrication
Understanding Lubricity and friction
Lubricity is the property of a lubricant that enables it to reduce friction between two surfaces. It is the ability of the lubricant to form a thin film that separates the two surfaces and allows them to slide against each other with minimal resistance. In simple words, it is the measure of how easily a lubricant can lubricate surfaces, minimizing friction and wear.
Friction is the resistance to motion that occurs when two surfaces come into contact with each other. It is the force that opposes the relative motion of two surfaces that are in contact. Friction causes wear and tear on surfaces, leading to equipment failure, increased energy consumption, and reduced productivity. The Relationship between Lubricity and Friction Lubricity and friction are directly related. The better the lubricity of a lubricant, the lower the friction between the surfaces it is lubricating. This, in turn, reduces wear and tear on the equipment, leading to increased efficiency and longer equipment life.
Thermal Management & Lubrication
Boron Nitride Powder With its high thermal conductivity and stability stands out as an ideal choice for thermal management, heat shielding, and lubrication. When mixed into lubricating oils, Boron Nitride powder particles improve lubricity, especially with smaller particle sizes and porous structures. This leads to reduced friction and wear while enhancing thermal conductivity, making Boron Nitride powder an invaluable component in various industrial applications.
