Barium sulfate sand is a natural mineral primarily composed of barium sulfate (BaSO₄), known for its high density, stability, and heat resistance. In industry, especially in the automotive parts manufacturing sector, barium sulfate is widely used as a filler in brake pads.
In the production process of brake pads, barium sulfate powder is added as a functional filler, with specific roles including:
1. Enhancing friction performance:
• The moderate hardness of barium sulfate powder can increase the friction coefficient when added to brake pad materials, allowing the brake pads to generate sufficient friction when in contact with the brake drum or disc during braking, effectively converting kinetic energy into heat to slow down or stop the vehicle.
2. High-temperature resistance:
• A large amount of heat is generated during braking, and barium sulfate has good high-temperature resistance, able to withstand rapid temperature increases in a short time while maintaining structural stability, preventing significant degradation of braking performance due to high temperatures.
3. Controlling wear rate:
• Adding barium sulfate powder helps regulate the wear rate of brake pads, ensuring necessary braking effectiveness while avoiding excessive wear that could shorten their lifespan.
4. Reducing costs:
• Compared to other expensive high-performance fillers, barium sulfate is relatively low-cost, helping to reduce the production costs of brake pads without sacrificing basic braking performance.
5. Improving mechanical properties:
• In composite materials, barium sulfate can also enhance the overall mechanical strength and toughness of brake pads, contributing to their durability under complex working conditions.
In summary, barium sulfate plays an important role in brake pad manufacturing by enhancing braking efficiency, stabilizing working conditions, extending service life, and optimizing costs. Additionally, due to its environmentally friendly and non-toxic characteristics, it meets the modern automotive parts' requirements for eco-friendly materials.
