Xiangsheng Carbon Fiber Powder - Strong Manufacturer Supply!

Carbon Fiber Powder is a cylindrical particle of equal length obtained by special surface treatment, grinding, microscopic identification, screening, and high-temperature drying of high-strength and high modulus carbon fiber filaments. Here are some detailed information about carbon fiber powder:

Performance characteristics:

Physical properties: The color is usually black gray, the shape is small, and the specific surface area is large. The diameter of its single filament is generally in the micrometer range, for example, the common one is around 7 micrometers. The density is relatively small, which makes it less likely to increase the overall weight when added to other materials.

Mechanical properties: It has high tensile strength, which significantly enhances the strength of composite materials. The coefficient of linear expansion is low, the thermal stability is good, and the size change is small when the temperature changes.

Electrical properties: With relatively low resistivity and good conductivity, it can be used in materials that require conductivity.

Preparation method:

The previous preparation method generally involved first decomposing and removing the sizing agent on the surface of carbon fibers at high temperatures, and then cutting, crushing, and grinding to obtain it.

There are also some new preparation techniques now, such as using special airflow crushing methods. Firstly, short cut high thermal conductivity carbon fibers are transported to the crushing chamber through a hopper, then evenly dispersed by micro positive pressure gas, and then oriented and arranged by a high-voltage electric field. Finally, filtered compressed air is used to accurately crush and collect the oriented short cut carbon fibers.

Application areas:

In the field of composite materials, it can be combined with materials such as resin, plastic, metal, rubber, etc. to increase the strength and wear resistance of the material. For example, in the manufacturing of automotive parts, adding carbon fiber powder to plastic can produce high-strength and lightweight components; Adding carbon fiber powder to rubber products can improve the wear resistance and tear resistance of rubber.

In the field of batteries, it is widely used as a conductive additive for the positive and negative electrode materials of nickel hydrogen and nickel cadmium batteries, which can improve the conductivity and charge discharge performance of batteries.

In the field of electronics, it is used for electronic chips, conductive boards, conductive floors, etc., to provide good conductivity and electromagnetic shielding performance for electronic devices.

In the field of national defense and military industry, due to its excellent performance, it can be used to manufacture high-performance weapon and equipment components, such as missile shells, aircraft structural components, etc.

Other fields: It can also be used for building insulation, chemical food coarse filtration, motorcycle mufflers, air filtration in paint drying rooms, polytetrafluoroethylene and other fields.

Safety precautions: Carbon Fiber Powder may pose certain hazards to the human body, such as causing skin allergies, itching, and other symptoms. Necessary protective measures should be taken during production and use, such as wearing masks, gloves, goggles, etc., to avoid direct contact with carbon fiber powder.
