Introduction and function of grease
Because everyone did not understand the role of grease when consulting the grease cone meter MHY-11485, today is the science for everyone.
Grease English name: lubricating grease; grease thick grease-like semi-solid. Used in the friction part of the machine for lubrication and sealing. Also used on metal surfaces to fill voids and rust preventive effects. Mainly composed of mineral oil (or synthetic lubricant) and thickener
The role of grease is primarily lubrication, protection and sealing.

Most greases are used for lubrication and are called anti-friction greases. Anti-friction grease mainly acts to reduce mechanical friction and prevent mechanical wear. At the same time, it also protects against metal corrosion and seals dust. Some greases are mainly used to prevent metal rust or corrosion, called protective grease. For example, industrial petroleum jelly has a small amount of grease for sealing, called sealing grease, such as thread grease. Most of the grease is a semi-solid material with unique fluidity.
Grease works on the principle that the thickener keeps the oil in the position where it needs to be lubricated. When there is a load, the thickener releases the oil and acts as a lubricant.
It is like a solid at normal temperature and at rest, and can maintain its shape without flowing, and can adhere to the metal without slipping. At high temperatures or when subjected to an external force exceeding a certain limit, it acts like a liquid to flow. When the grease is sheared by moving parts in the machine, it can flow and lubricate, reducing friction and wear between the moving surfaces. When the shearing action is stopped, it can restore a certain consistency. This special fluidity of the grease determines that it can be lubricated in areas that are not suitable for lubricating oil. In addition, since it is a semi-solid substance, its sealing action and protection are better than lubricating oil.
