(1) It has a satisfactory smoothing effect; that is, it can reduce the conflict of the bearing and press the harmful wear process in the bearing; the conflict resistance should be. Drumstick σ.
(2) Avoid bearing corrosion; itself does not cause corrosion, deformation or deformation of bearing components (such as copper cages, rubber seals, etc.).
(3) It can be within the upper and lower limits of the regular operating temperature; always maintain the necessary smooth function; the chemical composition is stable; the viscosity changes little.
(4) Within the range of the upper and lower limits of the regular operating speed; a satisfactory thick oil film can be established, which is self-contained; contains no impurities; and has excellent defoaming properties.
(5) Within the working period of the demand or during the inventory period; the physical function and chemical function are satisfactory and stable; the quality of the application is not affected.
(6) Protection; protection is concise; less dependent equipment.
(7) Under the premise of satisfying the above skills needs; economically strive to save.
2. Additional requirements for smoothing agents
(1) Excellent cooling effect.
(2) It has strong adhesion to the smooth appearance; leakage; dripping or scattering as little as possible, water separation is good.
(3) Mixing a small amount of impurities (such as moisture) does not affect its function.
(4) It has a sealing effect; it can prevent water or dirt from entering the bearing.
(5) It is not easy to transmit oscillation or reduce noise.
(6) It is possible to implement smooth gathering.
3. The unique need for smoothing agents is under unique conditions; it is necessary to have the following unique requirements for smoothing agents:
(1) Long-life demand demand The application life of smoothener is unique.
(2) The demand for low-conflict torque requires that the conflict resistance of the smoothing agent is very low.
(3) The demand for high temperature resistance requires a high temperature above 250 °C.
(4) Demand for low temperature resistance requires low temperature below 63 °C.
(5) The demand for high vacuum resistance is required under high vacuum conditions; no evaporation; no loss; no deformation; unique under high vacuum conditions of weightlessness.
(6) Harmless demand when used in food, pharmaceutical or chemical machinery; demand even if there are few micro-smooth agents mixed into food, medicine or chemical products; it will not lead to food poisoning, drug modification or chemical product transformation.
(7) The demand for smooth characteristics of the gap is in a polluted environment such as coal mines; solid impurities in the smoothing agent cause the oil film to be damaged and often in a smooth condition; the smoothing agent can be used to this condition.
