Age hardening: The appearance of the consistency of the grease added with the moment of storage.
Appearance: The grease characteristics seen only by visual inspection; generally include the overall appearance, texture, color and gloss.
Overall appearance: lubricated, rough, granular, oil-like, etc.: creamy, elastic, brushed color: red, blue, yellow, white, etc.; can also add constrained adjectives such as "light" "Medium", "deep" and other luster: bright, dull, etc.
Consistency: Consistency refers to the degree to which a plastic material resists deformation under the action of an external force.
Cone penetration: Cone penetration is a measure of the consistency of the grease. The greater the penetration, the softer the fat.
Consistency grade: NLGI (American Grease Association) is divided into nine grades; nine from 000 to 6.
Mechanical stability: the ability of the grease to resist the change of consistency when mechanically sheared; the more the consistency change value. The egg catches the glue.
Thixotropy: When the grease is sheared; the consistency changes. V辜 辜 惺 怀 怀 扔 扔 扔 扔 扔 扔 扔 扔 扔 扔 扔 扔 扔 扔
Water resistance: Grease resists the ability to be washed away from the bearing; resists the ability to damage the layout of the grease due to moisture absorption; the ability to avoid corrosion of the metal surface in the presence of water.
Colloidal stability: the ability of grease to resist oil separation.
