Characteristics of Molybdenum Dry Lubricant

  1. High strength and wear resistance: MDL has exceptionally high tensile strength and hardness, which can effectively resist friction and wear.
  2. High-temperature resistance and antioxidant properties: MDL can maintain stability at high temperatures and has excellent antioxidant properties.
  3. Low friction coefficient: The friction coefficient of MDL is lower than that of traditional lubricants, which can effectively reduce the friction resistance during mechanical operation.
  4. Oil-free maintenance: MDL is a dry lubricant that does not require oily lubricants, thus avoiding oil stains and contamination.

Application areas of Molybdenum Dry Lubricant

  1. Aerospace: In the aerospace field, MDL is widely used in high-precision, high-strength, and high-temperature components such as engines and bearings to improve their operational efficiency and extend their service life.
  2. Automotive industry: Automotive engines, transmissions, bearings, and other parts must withstand high temperatures and heavy loads, and MDL can provide efficient lubrication for these parts.
  3. Precision Machinery: In precision machinery, such as CNC machine tools, clocks, etc., MDL can ensure their high-precision and high-efficiency operation.
  4. Petrochemical: In the petrochemical industry, MDL is used in bearings, shaft sleeves, and other parts of high-temperature and high-pressure reaction vessels to improve equipment reliability and safety.

Preparation method of Molybdenum Dry Lubricant

  1. Raw material preparation: Select molybdenum powder with extremely high purity as the raw material.
  2. Compression molding: Place molybdenum powder in a high-temperature and high-pressure environment and press it into the desired shape of the billet.
  3. High-temperature sintering: The billet is sintered at high temperatures to form a strong metallurgical bond between molybdenum powders.
  4. Fine grinding: The sintered body is finely ground for a smooth surface and structure.
  5. Surface treatment: Surface treatment is applied to the ground green body to improve its oxidation resistance and friction performance.

Issues to note when using Molybdenum Dry Lubricant

  1. Correct installation and use: Follow the recommendations and guidelines in the product manual to ensure proper installation and use of MDL. Ensure compatibility with relevant equipment or components and operate according to recommended procedures.
  2. Prevent pollution: MDL should be stored in a dry and clean environment, avoiding contact with dust, dirt, or other impurities. Before use, ensure that the MDL surface is clean and free from contamination.
  3. Prevent excessive wear: Although MDL has excellent wear resistance, excessive or improper use may lead to excessive wear. Therefore, lubrication should be carried out according to the recommended dosage and usage time interval, and the wear of equipment or components should be checked regularly.
  4. Avoid high temperatures and environments: MDL may lose its performance at high temperatures. Therefore, during use, it is essential to avoid prolonged exposure to high temperatures and ensure that the equipment or components have cooled down before use.
  5. Pay attention to ventilation: MDL may release some gases during use. Therefore, maintain good ventilation around equipment or components using MDL to ensure timely gas discharge.
  6. Avoid contact with water: MDL in contact with water may affect its performance. Therefore, it is essential to avoid direct touch with water during use and ensure that the equipment or components have dried before use.
  7. Regular replacement: To maintain the performance of MDL and extend its service life, it is recommended to replace it according to the recommended replacement cycle. Timely replacement of old and worn MDLs to ensure the regular operation of the equipment and extend its service life.
