The Application of Magnesium Oxide Heavy in Brake Shoes Production
In the manufacturing of brake shoes, the choice of materials within the brake shoes friction materials is of utmost importance for the overall efficiency and safety of braking systems. Magnesium Oxide Heavy has become a key ingredient in brake shoes mixtures and mixes, bringing both benefits and challenges to the production process.
Advantages
- High – Temperature Resistance
- Magnesium Oxide Heavy exhibits excellent high – temperature resistance properties. In brake shoes, it can withstand temperatures up to 800°C without significant degradation. Tests have shown that when brake shoes with 15 – 20% Magnesium Oxide Heavy are subjected to extreme braking conditions that cause the temperature to reach 600°C, the friction performance remains stable. This high – temperature stability is crucial as it prevents brake fade, ensuring that the braking force remains reliable even during intense braking, such as in high – speed driving or continuous downhill driving.
- Enhanced Mechanical Strength
- It contributes to improving the mechanical strength of brake shoes. brake shoes mixes containing Magnesium Oxide Heavy have been found to have a 30 – 40% increase in compressive strength compared to those without it. This stronger structure allows the brake shoes to better withstand the mechanical stresses generated during braking, reducing the risk of deformation or breakage, and thus extending the service life of the brake shoes.
- Good Chemical Stability
- Magnesium Oxide Heavy has good chemical stability. It is resistant to most common chemical substances in the automotive environment, such as road salts and acidic pollutants. In a test where brake shoes with Magnesium Oxide Heavy were exposed to a solution simulating road – salt – contaminated water for 100 days, there was no visible chemical reaction or degradation, ensuring the long – term integrity of the brake shoes.
Disadvantages
- High Cost
- One of the major drawbacks of using Magnesium Oxide Heavy in brake shoes production is its relatively high cost. The price of Magnesium Oxide Heavy is approximately 2 – 3 times higher than some traditional brake shoe materials. This significantly increases the production cost of brake shoes, which may be a deterrent for manufacturers aiming to produce low – cost brake shoes for price – sensitive markets.
- Difficult Processing
- Magnesium Oxide Heavy has certain processing difficulties. Due to its high melting point and specific physical properties, it requires more energy – intensive processing methods during the production of brake shoes mixtures. For example, the mixing process may need to be carried out at higher temperatures and with more powerful mixing equipment, which not only increases the energy consumption but also complicates the production process.
In summary, Magnesium Oxide Heavy offers remarkable advantages in terms of high – temperature resistance, enhanced mechanical strength, and chemical stability in brake shoes production. However, its high cost and processing difficulties pose challenges that need to be carefully weighed by manufacturers when considering its application in brake shoes friction materials.
