Product Features:
Reduced iron powder is typically a gray or black powder made from iron oxides (such as Fe3O4 or Fe2O3) that are reduced at high temperatures using gases (like hydrogen or carbon monoxide) or solid reducing agents (like coke). The characteristics of reduced iron powder include:
High reducibility: Reduced iron powder has high chemical reactivity, easily reacting with oxygen in the air and can even ignite with slight heating.
Large specific surface area: The fine and porous particles provide a large surface area, facilitating rapid chemical reactions.
Loose structure: The microscopic structure is loose, making it easy to absorb moisture and oxygen, suitable for deoxidizers and desiccants.
High purity: Typically contains over 98.5% iron, with very low impurity levels, especially in carbon, phosphorus, and sulfur.
Application Industries:
Due to its unique chemical and physical properties, reduced iron powder has wide applications in various industries, mainly including:
Powder metallurgy: Used in the manufacture of various metal components, such as gears, bearings, and cams.
Chemical industry: Used as a reducing agent in chemical synthesis and catalytic reactions.
Food industry: Used as a deoxidizer in food packaging to extend shelf life.
Welding rod manufacturing: Improves welding efficiency and quality.
Friction materials: Used in brake pads, clutch plates, etc., to improve friction performance.
Electronics and battery industry: Used as a component in battery electrode materials.
Pharmaceuticals and biotechnology: Used as a raw material or catalyst in the synthesis of certain drugs and biocatalysis.
Application of reduced iron powder in brake pads:
In brake pads, reduced iron powder mainly plays the following key roles:
Regulating friction coefficient: Reduced iron powder helps to adjust the friction coefficient of brake pads, ensuring consistent braking performance under different temperature and humidity conditions.
Enhancing wear resistance: By mixing with hard particles, it improves the wear resistance of brake pads, extending their service life.
Reducing braking noise: Its unique structure helps to reduce vibrations and noise during braking.
Improving thermal management: The heat generated during braking can be dissipated through the structure of reduced iron powder, preventing performance degradation due to overheating.
Participating in chemical wear mechanisms: During friction, reduced iron powder may participate in forming a protective film, reducing wear on the metal substrate.
In summary, the application of reduced iron powder in brake pads can significantly improve braking performance, increase safety and reliability, while reducing maintenance needs.
