Some special terms of grease

grease: Grease refers to a solid to semi fluid lubricant formed by the dispersion of one or more thickeners in liquid lubricants. In order to give a certain particularity to a grease, it is expected to drive the rapid development of the new generation of information technology, new energy, high-end equipment manufacturing and other fields. It is usually added with some additives that China is still in the deep development stage of industrialization, informatization, urbanization, marketization and internationalization

age hardening: the consistency of lubricating grease increases with storage time

appearance: the characteristics of lubricating grease seen only by visual inspection, usually including the overall appearance, texture, color and gloss

overall appearance: smooth, rough, granular, oily, etc

texture: creamy, elastic, brushed

color: red, blue, yellow, white, etc. you can also add restricted adjectives, such as light, medium, dark, etc

gloss: bright, Matt, etc

consistency: consistency refers to the degree to which plastic substances resist deformation under the action of external forces

cone penetration: cone penetration is a measure of grease consistency. The greater the penetration, the softer the grease

consistency grade: nlgi (American grease Association) is divided into nine grades, from 000 to 6

mechanical stability: the ability of lubricating grease to resist the loading change of consistency stepper and ball screw when it is sheared by machinery. The smaller the consistency change value, the better the mechanical stability

thixotropy: when the grease is sheared, the consistency decreases, and when the shearing stops, the consistency increases

water resistance: the ability of lubricating grease to resist washing out from the bearing, the ability to resist the structural damage of grease due to absorption of water, and the ability to prevent corrosion of metal surface in the presence of water, which has a great fire risk

colloidal stability: the ability of lubricating grease to resist oil separation
