Details Introduction

Calcium sulfate whiskers are a high-tech, nano-scale inorganic fiber material, with the chemical formula CaSO₄·nH₂O, where the value of n represents different degrees of hydration, such as anhydrous calcium sulfate whiskers (CaSO₄) and hemihydrate calcium sulfate whiskers (CaSO₄·½H₂O). This material has a wide range of applications in various fields due to its unique microstructure and excellent physicochemical properties.

Characteristics and advantages of calcium sulfate whiskers:

1. High strength and high modulus: Calcium sulfate whiskers have extremely high tensile strength and bending modulus, making them ideal reinforcement materials.

2. Thermal stability and high-temperature resistance: Calcium sulfate whiskers have a high melting point and good thermal stability, maintaining their original shape and performance at elevated temperatures, suitable for applications that require high-temperature resistance.

3. Chemical stability and corrosion resistance: They are stable against various chemicals, insoluble in water, resistant to acid and alkali erosion, and exhibit good chemical inertness.

4. Excellent insulation properties: With a high dielectric constant and low dielectric loss, they are suitable for use as electronic packaging materials and insulating materials.

5. Easy to process and surface modification: Calcium sulfate whiskers can be surface-modified through physical or chemical methods to improve their compatibility and interfacial bonding with matrix materials.

Application and role of calcium sulfate whiskers in brake pads:

In the brake pad (brake lining) manufacturing industry, calcium sulfate whiskers are favored for their characteristics, mainly used in the following aspects:

1. Reinforcement and wear resistance: Added as a reinforcing filler to brake pad materials, calcium sulfate whiskers can significantly enhance the mechanical properties of brake pads, particularly increasing their wear resistance and compressive strength.

2. Improved friction performance: Calcium sulfate whiskers help to adjust and stabilize the friction coefficient of brake pads, especially under high-temperature conditions, reducing the thermal fade effect caused by continuous braking and extending the service life of the brake pads.

3. Environmentally friendly alternative: As traditional harmful substances like asbestos are gradually phased out, calcium sulfate whiskers serve as an eco-friendly alternative filler, meeting environmental requirements while also achieving or exceeding the performance standards of traditional materials.

4. Thermal conduction and heat dissipation: The good thermal conductivity of calcium sulfate whiskers also helps brake pads dissipate heat quickly during braking, preventing local overheating that could lead to brake failure.

Therefore, calcium sulfate whiskers have become an indispensable part of modern high-performance brake pad formulations, enhancing the overall efficiency and safety of braking systems.
