Lithium Molybdenum Disulfide Grease It is made by thickening high-viscosity refined mineral oil with lithium hydroxy fatty acid soap, adding ultra-fine high-purity molybdenum disulfide solid powder and various additives such as anti-oxidation and anti-rust.
Features: The product has excellent extreme pressure and anti-wear properties, which can effectively reduce the frictional resistance of the mechanical lubrication parts and prolong the service life of the machinery. Scope of application: It is suitable for the lubrication of gears and bearings of various heavy-duty machinery and general speed equipment such as rolling machinery, construction machinery, heavy lifting machinery, etc. Temperature range: -20°C~120°C Why is molybdenum disulfide grease lost during use? Today I will share with you:
There are three main reasons for the loss of molybdenum disulfide grease during use: 1. Chemical reasons: Due to the heat and air in the friction lubrication part, the Base Oil and thickener are oxidized, resulting in damage to the soap structure and softening loss during use. 2. Physical reasons: Due to the operation of the friction part, the oil is continuously affected by shear stress, which damages the soap structure, softens, and loses impurities. 3. Environmental reasons: The moving body is worn, and these metal powders can accelerate the oxidation of the grease to generate organic acids, destroy the structure of the grease, and cause the failure of the grease. Selecting the grease correctly according to the working conditions of the equipment (including load, temperature, speed, etc.) can prolong the service life of the grease.
Molybdenum disulfide grease should be selected for harsh environments. The environment where the lubricating part is in contact with the medium has a great influence on the performance of the grease, so it should be carefully considered when selecting the grease. Do not use on wet or water-contact areas. Due to the poor water resistance of molybdenum disulfide grease, it is easy to dilute and emulsify in contact with water. Some parts cannot meet the requirements of molybdenum disulfide grease. For example, vertical pump bearings are often immersed in water and emulsified with molybdenum disulfide grease, resulting in short service life and easy bearing damage. These parts should use molybdenum disulfide grease with good water resistance.
