When Is It The Right Time To Use A Dry Lubricant?

Dry lubricants tend to be used in situations where liquid lubricants turn out to be messy. But the main use of a dry lubricant is to reduce the friction levels between a couple of moving surfaces. There is another reason for using a dry lubricant, as it can withstand a lot of heat when compared to its counterparts. Numerous types of materials exist that may be used as a dry lubricant.
Dry lubricant and the various types
Some of the common types of dry lubricants are hexagonal boron nitride, graphite, and molybdenum disulphide. Graphite is to be used if you are planning to apply it to railway track joints, track compressors, and machine work shops. In fact, these turn out to be a few examples for which you may use graphite.
If you are using molybdenum disulphide, its common use is in space vehicles. On the other hand, if you are using hexagonal boron nitride, you may use it for space vehicles too. HBN is often termed “white graphite.” The material is known to operate at temperatures of around 350 degrees Celsius as part of oxidising environments. When it is molybdenum disulphide, the temperatures may shoot up to 1100 degrees Celsius.
When a couple of objects roll across each other, or if they need to move across each other under extreme pressure, then solid lubricants tend to be a lot more effective. This is when compared to the other types of lubricants. If either of these scenarios were known to occur, between two objects, the liquid lubricant would be squeezed out, though a dry lubricant would continue to function in a smooth manner.
Such type of properties tends to arise due to a molecular layered structure where between layers the bond is weak. Though these layers are able to slide in relation, when you apply minimal side force.For this reason it provides low fiction between the properties. Another area where dry lubricant is useful is in pots or pans. The choice of a lubricant depends upon your preferences.
