Advantages in Brake Shoes
1. Enhanced Friction Performance
Zircon powder helps to improve the friction coefficient of brake shoes. In the Brake Shoes Friction Materials, it provides a stable and consistent frictional force. This ensures reliable braking performance under various conditions, whether it’s normal daily driving or high – speed emergency stops. For example, during repeated braking, the presence of zircon powder helps maintain the friction level, reducing the risk of brake fade.
2. Heat Resistance
With its high melting point, zircon powder can withstand the extreme heat generated during braking. When the brake shoes are in contact with the brake drums or rotors, a large amount of heat is produced. Zircon powder in the Brake Shoes Mixture helps to dissipate this heat effectively and prevents the degradation of other Brake Shoes Ingredients due to overheating. This heat resistance contributes to the longevity of the brake shoes.
3. Wear Resistance
The hardness of zircon powder makes the brake shoes more resistant to wear. As the brake shoes rub against the brake components during braking, they are subject to abrasion. Zircon powder in the Brake Shoes Mixes acts as a reinforcing agent, reducing the rate of wear and tear. This results in longer service life of the brake shoes and less frequent replacements.
4. Chemical Stability
Zircon powder is chemically stable, which means it does not react easily with other substances in the Brake Shoes Formula. This stability ensures that the performance of the brake shoes remains consistent over time and is not affected by environmental factors such as moisture, oxidation, or exposure to chemicals on the road.
Storage and Packaging
Storage
- Temperature and Humidity: Zircon powder should be stored in a cool, dry place. High humidity can cause the powder to agglomerate, which may affect its performance in the brake shoes formula. The ideal storage temperature range is between 10 – 30 °C, and the relative humidity should be kept below 60%.
- Ventilation: The storage area should be well – ventilated to prevent the accumulation of dust. Adequate ventilation helps to maintain a safe working environment and prevents potential explosion hazards associated with fine dust particles.
- Separation: It should be stored separately from incompatible materials such as strong acids and alkalis to avoid chemical reactions.
Packaging
- Containers: Zircon powder is typically packaged in sealed plastic bags or drums. The bags or drums should be made of materials that are resistant to moisture and dust. For example, polyethylene bags with a thickness of at least 0.1 mm can be used to prevent moisture ingress.
- Labeling: Each package should be clearly labeled with the product name, batch number, date of manufacture, and relevant safety instructions. This information is essential for proper handling and traceability.
In conclusion, zircon powder is a valuable brake shoes ingredient that significantly contributes to the performance, durability, and safety of brake shoes. By understanding its technical parameters, advantages, and proper storage and packaging methods, manufacturers can ensure the optimal use of zircon powder in their brake shoes formulas.
