The friction and wear of machinery is the main reason for causing the excessively high mechanical energy consumption of all operatings and damage.According to relevant information
Statistics：The expenses such as maintenance, repair, stop work and production of the modern industry because rubbing, wearing generation account for gross national product
15%~30%.
Calculate according to related authoritative institution：In friction loss, machinery is set for 30%~50% consumption of the disposable energy in the world
Standby to damage and failure about 80% is as caused by friction abrasion, and the serious accident of more than 50% mechanical equipment is all due to
Excessive wear caused by lubrication failure.
The secondary abrasion of reduction friction is the most frequently used and most simple effective method is lubricated using lubriation material, lubricating oil
Or lubricating grease is the lubriation material generally used at present, since most of lubricating oil or lubricating grease are to generate one between friction is secondary
The thin lubricating oil film of layer, reduces coefficient of friction and abrasion, but this layer of oil film is more easily damaged in use, and easily becomes
Matter and fail, easily generate deposit, therefore lubricant effect is difficult to the requirement for meeting many application scenarios.
The defects of in order to make up lubricating oil, often adds in various organic matters or inorganic matter to increase in lubricating oil or lubricating grease
The greasy property of strong lubricant grease improves the bearing capacity of lubricating film and reduces coefficient of friction.
Since conventional lubrication is theoretical and lubrication product is established in the forties in last century and gradual perfection gets up, when so far
