Silica fume is actually a form of silica ash, but it usually refers to the ultra-fine silicon dioxide powder obtained as a by-product in industrial production. However, the term 'silica fume' mentioned in the market may be a figurative description of certain characteristics of silica ash, or it may refer to fibrous products containing silicon materials, such as silicon-based fiber materials used in friction materials or brake pads. For clarity, this discussion will mainly focus on the properties of silica ash and its applications in brake pads, although 'silica fume' may refer to different types of silicon-based materials.

Details Introduction

Silica fume is actually a form of silica ash, but it usually refers to the ultra-fine silicon dioxide powder obtained as a by-product in industrial production. However, the term 'silica fume' mentioned in the market may be a figurative description of certain characteristics of silica ash, or it may refer to fibrous products containing silicon materials, such as silicon-based fiber materials used in friction materials or brake pads. For clarity, this discussion will mainly focus on the properties of silica ash and its application in brake pads, although 'silica fume' may refer to different types of silicon-based materials.

Product characteristics of silica fume:

Small particle size: Silica fume consists of micron-level ultra-fine particles with a large specific surface area.

High purity: The main component is silicon dioxide (SiO₂), with a purity typically above 90%.

Volcanic ash activity: It has strong chemical activity, capable of reacting with cement hydration products to form a stronger gel.

Filling performance: It can fill the micro-pores in concrete, improving its density.

Application industries:

Silica fume is mainly applied in the following fields:

Building materials: Used in high-performance concrete to enhance its strength, durability, and impermeability.

Petroleum industry: Used as an additive in drilling fluids to improve the rheological properties of the drilling fluid.

Casting industry: Used as a binder for casting sand to improve the surface quality and dimensional accuracy of castings.

Friction materials: Used in brake pads, clutch plates, and other friction materials to enhance their wear resistance and thermal stability.

Application in brake pads:

The application of silica fume (or so-called 'silica fume') in brake pads is mainly reflected in the following aspects:

Enhanced wear resistance: The high hardness and small particle size of silica fume can enhance the wear resistance of brake pads, extending their service life.

Improved thermal stability: The high temperatures generated during braking can lead to a decline in brake pad performance; silica fume can improve the thermal stability of brake pads, reducing thermal fade.

Improved friction performance: The activity of silica fume helps to form a more uniform and stable friction surface, increasing the friction coefficient of brake pads and ensuring braking effectiveness.

Reduced noise and vibration: Silica fume helps to reduce vibrations during braking, thereby lowering brake noise.

Promoting material bonding: In the composite materials of brake pads, silica fume can act as a filler and binder, enhancing the bonding between components and improving the overall stability of the material.

Therefore, the application of 'silica fume' in brake pads is primarily aimed at improving the performance of brake pads, including enhancing wear resistance, thermal stability, and friction performance, while reducing noise and vibration during braking, ultimately enhancing driving safety and comfort.
