Details Introduction

Needle-like wollastonite powder is a unique silicate mineral, typically represented by the chemical formula Ca[SiO₃(OH)], theoretically composed of calcium and silicate chains. This mineral appears in needle-like or fibrous forms and possesses excellent physical and chemical properties, making it widely used in various industrial fields.

Product Characteristics:
Form: Fibrous or needle-like structure with a high aspect ratio, reaching up to 20:1 to 30:1, which gives it excellent reinforcement properties.
Thermal Stability: It has a low thermal expansion coefficient and a high melting point, allowing it to remain stable in high-temperature wollastonite environments.
Electrical Properties: High resistance and low dielectric constant, suitable for electrical insulation materials.
Mechanical Properties: High hardness and good mechanical strength, suitable for reinforcing composite materials.
Chemical Stability: Resistant to most chemicals and not easily corroded.
Optical Properties: High refractive index, can be used in transparent or translucent materials.

Application Industries:
Needle-like wollastonite is widely used in various industries due to its unique properties:
Building Materials: Used to reinforce concrete, mortar, tile adhesives, etc., improving the strength and durability of materials.
Friction Materials: Used as a reinforcement in automotive brake pads and clutch plates, improving friction performance and wear resistance.
Plastics and Rubber: Used as a filler to enhance the mechanical properties of materials, such as increasing impact strength, tensile strength, and wear resistance.
Papermaking: Used as a filler to improve the whiteness, opacity, and smoothness of paper.
Ceramics: Used in the production of special ceramics, such as fiber ceramic boards and sanitary ceramics.
Cable Industry: Used as a halogen-free flame retardant to improve the flame retardant properties of cables.
Metallurgy: Used as a flux to improve the smelting process.

Application in Brake Pads:
The application of needle-like wollastonite in brake pads is primarily based on its reinforcement properties and wear resistance:
Enhanced Friction Performance: The fibrous structure of needle-like wollastonite helps form a denser composite material, increasing the friction coefficient of brake pads.
Improved Wear Resistance: High hardness and good mechanical strength reduce wear on brake pads under high-intensity friction.
Improved Thermal Management: The low thermal expansion coefficient helps maintain structural stability of brake pads at high temperatures, avoiding thermal degradation.
Extended Service Life: Due to its high mechanical strength and thermal stability, needle-like wollastonite helps extend the service life of brake pads.
Noise Reduction: The fibrous structure helps reduce vibrations during braking, lowering noise levels.

In summary, needle-like wollastonite plays an important role in brake pads and other industrial applications due to its unique fibrous structure and excellent physical and chemical properties, significantly enhancing product performance and durability.
