Overview of Natural Expandable Graphite 32mesh 90% Carbon 150times Expansion Ratio

Graphite powder, a form of carbon, is a soft, black, greasy-feeling powder composed of minute, flexible crystalline flakes. It is a naturally occurring mineral but can also be synthesized industrially. Known for its unique electrical and thermal conductivity, lubricity, and resistance to high temperatures, graphite powder finds extensive applications across various industries due to its multifaceted properties.

Features of Natural Expandable Graphite 32mesh 90% Carbon 150times Expansion Ratio

  1. High Electrical Conductivity: Graphite powder is an excellent conductor of electricity, making it suitable for use in batteries, electrodes, and other electrical applications.

  2. Thermal Conductivity: It efficiently conducts heat, useful in heat sinks and applications where heat transfer is crucial.

  3. Lubricity: The flake-like structure of graphite provides natural lubrication, reducing friction between surfaces without leaving a sticky residue.

  4. Chemical Stability: Resistant to most acids and alkalis, graphite maintains its properties even in harsh chemical environments.

  5. High Temperature Resistance: Graphite can withstand extreme temperatures without losing its structural integrity, making it ideal for high-heat applications.

  6. Anisotropic Properties: Its properties vary along different crystal axes, enabling tailored applications that exploit these directional characteristics.

Parameter of Natural Expandable Graphite 32mesh 90% Carbon 150times Expansion Ratio

The "natural expandable graphite 32mesh 90% carbon 150times expansion ratio parameter" refers to the specific properties of natural expandable graphite that have been chosen for use in a particular product or application. Natural expandable graphite is a type of grapheme that is made up of small, closely packed carbon molecules that can expand and contract with temperature changes. This makes it an excellent material for use in products where the mechanical properties of the material must be able to change depending on its environmental conditions. In this case, the "32mesh" refers to the size of the mesh on which the carbon molecules are packed. A larger mesh allows for more frequent adjustments to the size of the material as needed, while still maintaining good mechanical strength and durability. The "90%" carbon content indicates that the carbon content in the material is at least 90%, meaning that it contains at least 90% of the carbon atoms in the grapheme. Finally, the "150times expansion ratio" parameter specifies how much the material expands or contracts when it is subjected to thermal stress. A higher value for this parameter indicates that the material will expand or contract more than average, which may be desirable in certain applications where rapid changes in volume are necessary. However, too high a value for this parameter could result in reduced durability or increased weight of the material.

Applications of Natural Expandable Graphite 32mesh 90% Carbon 150times Expansion Ratio

  1. Metallurgical and Foundry Industry: As a lining for crucibles and molds due to its high melting point and low reactivity.

  2. Battery Manufacturing: Used in lithium-ion batteries as a conductive additive and in lead-acid batteries as a part of the electrode mixture.

  3. Lubricants: Added to greases and oils to enhance lubrication properties, especially in high-temperature or chemically aggressive environments.

  4. Sealants and Gaskets: Incorporated into sealing materials to improve heat resistance and self-lubrication.

  5. Pencil Leads and Art Supplies: Pure graphite powder or mixed with clay forms the core of pencils and is used in various artistic mediums.

  6. Electrical and Electronic Applications: As a component of electrodes, conductive coatings, and as a filler in polymer composites for EMI/RFI shielding.

FAQs of Natural Expandable Graphite 32mesh 90% Carbon 150times Expansion Ratio

Q: Is Natural Expandable Graphite 32mesh 90% Carbon 150times Expansion Ratio toxic? A: Natural Expandable Graphite 32mesh 90% Carbon 150times Expansion Ratio is generally considered safe to handle. However, inhalation of fine particles can cause respiratory irritation, so appropriate safety measures should be taken during handling.

Q: How is Natural Expandable Graphite 32mesh 90% Carbon 150times Expansion Ratio different from graphene? A: Graphene is a single layer of carbon atoms arranged in a hexagonal lattice, whereas Natural Expandable Graphite 32mesh 90% Carbon 150times Expansion Ratio consists of many layers of these sheets bonded together. Graphene is much thinner and exhibits different properties.

Q: Can Natural Expandable Graphite 32mesh 90% Carbon 150times Expansion Ratio conduct electricity underwater? A: Yes, graphite is a good conductor of electricity even when submerged, making it suitable for underwater applications like marine coatings and submersible equipment.

Q: Is Natural Expandable Graphite 32mesh 90% Carbon 150times Expansion Ratio flammable? A: Graphite itself is not flammable as it is a form of carbon. However, in certain circumstances, it can facilitate combustion by conducting heat.

Q: How is Natural Expandable Graphite 32mesh 90% Carbon 150times Expansion Ratio produced? A: Natural graphite is mined and then processed into powder through crushing, milling, and sometimes chemical treatments. Synthetic graphite is produced through high-temperature heating of carbonaceous materials in the absence of oxygen.
