FORMULTION PERFORMANCE
BL – ACV – D7 represents a highly economical bus formula. Composed as a low – metallic brake block formulation, it consists of a well – balanced low – metallic brake block mixture. This mixture is carefully crafted using a variety of chemical powders that contribute to its stable performance. As a result, it is an ideal choice for price – sensitive markets and customers who seek reliable yet cost – effective solutions.
Characteristics
The BL – ACV – D7 formula endows brake products with an impressive 50 – 80 thousand KM lifetime. This longevity is a testament to the durability of the low – metallic brake block friction materials used in its composition. These materials are engineered to withstand the rigors of continuous use, ensuring that vehicles equipped with brakes made from this formula can operate smoothly over long distances.
Applicable Car Models
It is specifically designed for the low – end and mid – range markets. Given its characteristics, it is particularly suitable for light trucks. In these vehicles, the performance of low – metallic brake linings formulated with BL – ACV – D7 can meet the demands of daily operations, whether it’s for urban deliveries or short – haul transportation.
PHYSICAL PROPERTIES
- Constant Speed Coefficient: With a constant speed coefficient of 0.35, the braking performance remains consistent under steady – state driving conditions. This coefficient is a crucial factor in ensuring smooth deceleration, which is essential for the safety and comfort of vehicle occupants.
- AK MASTER Coefficient: The AK MASTER coefficient of 0.33 indicates excellent braking stability under various conditions. It plays a significant role in maintaining the integrity of the braking system, especially during high – stress braking situations.
- Krauss Coefficient: A Krauss coefficient of 0.32 further attests to the formula’s reliability. This value is related to the material’s ability to dissipate heat effectively during braking, preventing overheating and maintaining optimal braking performance.
- Bulk Density: The bulk density of 1.3 is carefully calibrated to ensure the proper packing of the low – metallic brake block mixture. This density affects the overall performance of the brake block, including its ability to withstand pressure and transfer force efficiently.
- Compacted Density: At a compacted density of 3.0, the brake blocks formed from this formula are dense and robust. This high density contributes to the durability and long – lasting performance of the brakes.
- Compression of Normal Temp.: The compression of normal temp. is 100μm ± 20. This property ensures that the brake linings can adapt to normal operating temperatures without significant deformation, maintaining consistent braking force.
- Compression of High Temp.: When it comes to high – temperature conditions, the compression is ≤300μm. This shows the formula’s ability to withstand heat generated during intense braking, preventing excessive wear and ensuring the safety of the braking system.
- Porosity: With a porosity of ≥9.5%, the brake blocks have sufficient space for heat dissipation and gas escape. This porosity is vital for maintaining the performance of the low – metallic brake block friction materials, especially during continuous or high – speed braking.
- Rockwell Hardness: The Rockwell hardness of 60±10HRS ensures that the brake blocks are hard enough to resist wear but not too hard to cause excessive damage to the brake rotors. This balance is crucial for the overall lifespan of the braking system.
- PH: The pH value ranging from 9 – 12 indicates the chemical stability of the formula. This pH level helps in preventing corrosion and degradation of the low – metallic brake block mixture, ensuring its long – term performance.
- Shear Strength: A shear strength of ≥3.5Mpa means that the brake blocks can withstand the forces exerted during braking without breaking or separating. This strength is essential for the reliable operation of the braking system.
- Chase J661 Friction Degree: The Chase J661 friction degree of FF indicates a consistent and reliable friction level. This friction is precisely tuned to provide effective braking force while minimizing noise and vibration.
PACKAGE AND STORAGE
- Packaging Options: The product is available in 25KG/bag, with double – sheet paper bags providing a basic and cost – effective packaging solution. For those who require more robust protection, wooden boxes with plastic bags are also an option. Additionally, customized packs can be arranged to meet specific customer needs, whether it’s for ease of transportation or storage requirements.
- Storage Precautions: Once opened, bags must be carefully resealed to prevent any leakage of the low – metallic brake block mixture. Keeping the bags upright is crucial as it helps maintain the integrity of the product and prevents any potential spillage. The product should be stored in its original packages in a dry, cool, and well – ventilated area. This is to protect the low – metallic brake linings chemical powder from moisture, heat, and direct sunlight, all of which can degrade its quality and performance.
- Environmental Considerations: When using the BL – ACV – D7 formula, it is essential to use it appropriately to avoid environmental contamination. The chemical components in the low – metallic brake block formulation should be handled with care, and any waste generated during the manufacturing or use process should be disposed of in an environmentally friendly manner.
