Compatibility testing of rubber and pla✘≈$stic

Applicability Properties, Performance testingBy ODR 2025-03-07

Definition: Grease and synthetic rub©‍ber compatibility refers to the abil©§ity of grease to maintain the volume aλ₩αnd hardness of standard elastomers u™ nchanged when in contact with greas♠☆γe. It is expressed as a p★♣≤ercentage of volume change. ① Poor c→"ompatibility of grease ♣φcan cause changes in ↓ the elasticity of rubber ← materials, leading to increase≈λ≈♥d or decreased…

Wear resistance testing

Mechanical Properties, Performance testingBy ODR 2025-03-07

Definition: Grease anti-wear pΩ∞erformance refers to the ability of ‌↑grease to prevent wear ♦♦φ∞on lubricated components in hi✘↕§gh-load operating equipment. ① Fo₽¶<✔r metal machinery, due to the π↕≥relative motion of metal surfaces, δ‍friction causes metal to seλ₩‌parate and peel off from €"the surface, resulting in a l♣'γ&oss of weight or chan♠€↓♣ges in the volume and…

Oxidation stability testing

Chemical Properties, Performance testingBy ODR 2025-03-07

Definition: Refers to th♣'e ability of grease to reπ©sist oxidation during sto₩δ©®rage or when used under high-t∑☆'↔emperature conditions. σβ®€① The metal soap and base oil comp₩©onents in grease are prone to oxidation§₽φ during long-term stπ∏ ♥orage or prolonged exposure ☆✘to high temperatures and air. Oxidati♦≈γon results in grease deteri‍β₽oration, a decrease in dropp♥♠ing point, the formation&helα ✔∏lip;

Mechanical stability

Mechanical Properties, Performance testingBy ODR 2025-03-07

Definition: Refers to the abi¥γlity of grease’s structural s÷§ystem to resist deform¥∏₹✔ation and flow under mechanical sφε★hear forces. ① Mechanical stability i≥‍s an important performan€‍ce characteristic of grβ↑ease and a key facto♠πr affecting its service life. α÷② The mechanical stability of greas‍≥πe mainly depends on the type of thic δkener and the preparation process. ③ Me±©λ thods…

Copper corrosion detection

Chemical Properties, Performance testingBy ODR 2025-03-07

Definition: The grease copper corros $‌ion test refers to the abili•¥ty of grease to protec™₩t metal copper sheets from corrosion,÷₩ which has become one of the main phys≥ ical and chemical properties.∞ ① The significance ✘∏♦of grease copper corrosφ ion lies in determining the c∞≥orrosiveness of grea↕λ≠‌se to metal and its ability to protΩ×★ect metals from corrosion. Th←$₩"is…
