Information About High Temperature Lubricants

By Christopher Eyres


Many companies and industries encounter losses when their machines break down due to wearing. One of the reasons behind this problem is friction. That's the reason why it is important to use lubricants, which may be liquid lubricants, solid lubricants, or high-temperature lubricants, so that friction is reduced.

Engines and other power equipments experience a lot of friction occuring between the surfaces inside them. Folks customarily do not notice this because the effects aren't visible until the machines start showing it by not working correctly.

Lubricants can be gotten in grease form, powder form, Teflon tape and many more. Graphite, tungsten disulfide and molybdenum disulfide are an example of dry lubricants that work simply fine even if exposed at temperatures as high as 350 degrees Celsius.

Why should we use lubricants? Lubricants perform a large amount of functions that would make industries save a lot of money. Like what I discussed earlier, they cut back the friction between two surfaces and ensure that parts that are supposed to move are kept moving. They transfer heat and eliminate debris and contaminants. They also transmit power. They supply cover against wear and corrosion too . They remove the risk of producing fire or forming smoke in objects.

High-temperature lubricants are probably a nice example to show how lubricants can stop fire and other deadly stuff from going down. This particular sort of lubricator is employed in jet turbines, which are operated at raised levels of temperature. It can overcome the issue of doing its job even at above ordinary temperature and keeping the pumpability temp to a minimum.

Lubricants can be divided into solid lubricants, gas lubricants and liquid lubricants ( which include suspensions and emulsions ).

Solid lubricants are also thought of as dry lubricants. They are specified into 3, specifically PTFE or Teflon, metal or amalgamate, and non-metals. Teflon is used in several cooking utensils because of its ability to make a surface non stick. It operates at temperatures not greater than 350 degrees Celsius. Non-metal lubricants like molybdenum disulfide, graphite, tungsten disulfide and hexagonal boron nitride are utilized in operations that need hot temperature. However , they have poor oxidization resistance. Metals and alloys like zinc, tin, gold, cadmium, bronze and lead are used plating and as slide bearings.

Gaseous lubricants have high compressibility and low viscosity in comparison to liquid lubricants. Some examples are technical gases, liquid-metal and steam vapors. Liquid lubricants are frequently oil-based like lanolin, synthesised oils and mineral oils.
