Solid Lubricants In A Variety of Forms for Machine Lubrication

All industrial machinery require routine maintenance to stay in good working order and deliver satisfactory results. Apart from cleaning these machine parts, lubricants are a regular practice of maintenance routine. Solid lubricants are typically favored in most industries due to their numerous helpful features. However, users should be aware of the various forms of dry lubricants that can be used instead of oil or grease for lubrication.

Solid lubricants that are commonly used

The most popular dry lubricant is molybdenum disulphide (MoS2), which can be utilised in a wide variety of temperatures. It binds firmly to the substrate surface and prevents corrosion of the underlying substance. It also minimizes friction between two surfaces, even when they have large weights on them. Under high pressure, it prevents the sliding surfaces from falling out of their places.

Graphite is a low-cost dry lubricant that may be found in almost any market. In a humid environment, the lubricating quality of graphite improves, protecting machinery from rusting. Even at high temperatures, it remains stable and maintains its low friction coefficient value, even when large amounts of heat are emitted over time.

Another common dry lubricant used in cookware coating is polyethylene (PTFE). It decreases friction between machine sliding surfaces. However, it only has a low friction coefficient when the load isn't too heavy. Over surfaces, it generates a colorless coating layer. Because of its low thermal conductivity and melting point, it is unlikely to be suitable for use in big industrial equipment.

Another dry lubricant that generates a glazy and smooth coating over substrates is fluoropolymer. It does not require vast volumes because a single coating of this lubricant is sufficient to maintain substrates lubricated and corrosion-free. It sticks to substrate materials quite well and does not peel off under pressure.

Xylan, boron nitride, calcium fluoride, talc, cerium fluoride, and tungsten disulfide are other varieties of dry lubricants that can be used in different industries. Thus, large amounts of these lubricants are manufactured to meet demands of business owners.
