Compatibility testing of rubber and plastic

Applicability Properties, Performance?testingBy ODR 2025-03-07

Definition: Grease and synthetic rubber compatibility refers to the ability of grease to maintain the volume and hardness of standard elastomers unchanged when in contact with grease. It is expressed as a percentage of volume change. ① Poor compatibility of grease can cause changes in the elasticity of rubber materials, leading to increased or decreased…

Wear resistance testing

Mechanical Properties, Performance?testingBy ODR 2025-03-07

Definition: Grease anti-wear performance refers to the ability of grease to prevent wear on lubricated components in high-load operating equipment. ① For metal machinery, due to the relative motion of metal surfaces, friction causes metal to separate and peel off from the surface, resulting in a loss of weight or changes in the volume and…

Oxidation stability testing

Chemical Properties, Performance?testingBy ODR 2025-03-07

Definition: Refers to the ability of grease to resist oxidation during storage or when used under high-temperature conditions. ① The metal soap and base oil components in grease are prone to oxidation during long-term storage or prolonged exposure to high temperatures and air. Oxidation results in grease deterioration, a decrease in dropping point, the formation…

Mechanical stability

Mechanical Properties, Performance?testingBy ODR 2025-03-07

Definition: Refers to the ability of grease’s structural system to resist deformation and flow under mechanical shear forces. ① Mechanical stability is an important performance characteristic of grease and a key factor affecting its service life. ② The mechanical stability of grease mainly depends on the type of thickener and the preparation process. ③ Methods…

Copper corrosion detection

Chemical Properties, Performance?testingBy ODR 2025-03-07

Definition: The grease copper corrosion test refers to the ability of grease to protect metal copper sheets from corrosion, which has become one of the main physical and chemical properties. ① The significance of grease copper corrosion lies in determining the corrosiveness of grease to metal and its ability to protect metals from corrosion. This…

Water resistance testing

Mechanical Properties, Performance?testingBy ODR 2025-03-07

Definition: Refers to the ability of grease to resist being washed out of ball bearings by water under test conditions. This is a critical factor when selecting grease for machinery operating in humid environments. ① Under specific conditions, the percentage mass of grease washed away by water is measured. The smaller the loss, the less…

Low temperature torque

Mechanical Properties, Performance?testingBy ODR 2025-03-07

Definition: Refers to the degree to which grease hinders the rotation of low-speed ball bearings (open type 204 bearings) under low-temperature conditions. ① Low-temperature torque indicates the low-temperature performance of grease. Using a torque of 9.81 N·cm (1000 g·cm), the lowest temperature at which the bearing completes one rotation within one minute is measured as…

Oil separation detection

Performance?testing, Physical PropertiesBy ODR 2025-03-07

Definition: Grease steel mesh oil separation refers to the tendency of base oil to separate from grease under heated conditions, indicating the quality of the grease’s colloidal stability when subjected to heat. ① Steel mesh oil separation is an important indicator of colloidal stability, which can predict changes in the structural framework of grease under…
