Description
Technical Field
The utility model belongs to the technical field of the lubricating grease technique and specifically relates to a lubricating grease adhesiveness test device.
Background
Greases are widely used in mechanical and automotive parts to protect components from friction and wear, and the interaction characteristics such as tackiness become key factors that affect the performance of the greases. Tackiness is related to the microstructural aspects of the grease, such as thickener networks, wetting agents, and additives.
Greases require both adhesive and cohesive tack to perform their function. The grease without adhesion will slip off the surface and will not spread inside the bearing, whereas the grease without adhesion will be thrown off the surface due to the centrifugal forces in the rotating machine.
Grease tackiness can be observed by two methods, either cohesion tackiness or adhesion tackiness. Cohesive-force tack refers to the internal strength of a grease, which depends on the attractive forces between molecules in the substance. Cohesion tack helps prevent the lubricating grease from being pulled apart by the applied shear forces. Greases with good cohesion tack are viscous, have little oil leakage, and perform well in mechanical rolling stability, working cone penetration, and water spray tests. Adhesion tack is the external attraction between grease and other surfaces, which depends on the attraction between different molecules. Adhesion tack helps the grease adhere to the surface and prevents it from being rubbed or thrown off. Greases require both adhesive and cohesive tack to perform their function.
The grease without adhesion will slip off the surface and will not spread inside the bearing, whereas the grease without adhesion will be thrown off the surface due to the centrifugal forces in the rotating machine.
Although tackiness is an important index parameter for handling greases, there is currently no clear way to quantify the tackiness of greases.
The method for testing the adhesion force of the lubricating grease at present mainly comprises the following steps: grease adhesion was evaluated by grasping a suitable amount of grease with the thumb and forefinger, and then separating slowly to see how long they were in series. This method is not accurate enough, is subjective, and cannot quantitatively determine the tackiness of the grease.
