Product Description

Overview of Expanded graphite powder

Dry graphite lubricants are specialized lubricating products that utilize graphite, a naturally occurring form of carbon, as their primary lubricating agent. Unlike traditional liquid oils or greases, dry graphite lubricants are in a powdered or solid form, providing lubrication through a dry film. These lubricants are known for their ability to operate effectively in high-temperature environments, under heavy loads, and in the presence of corrosive chemicals, making them suitable for a wide array of industrial and mechanical applications.

Features of Expanded graphite powder

  1. High Temperature Resistance: Can withstand extreme temperatures without breaking down, suitable for use in applications exceeding 1000°F (538°C).

  2. Low Friction: Graphite's layered structure provides a slippery surface, reducing friction between mating parts, and preventing seizing or galling.

  3. Chemically Inert: Resistant to most chemicals and solvents, making it ideal for corrosive or acidic environments.

  4. Water Repellency: Naturally hydrophobic, dry graphite lubricants can function effectively in wet environments, resisting washout and rust formation.

  5. Versatility: Applicable on a variety of surfaces including metal, plastic, and wood, and suitable for both static and dynamic applications.

  6. Clean Operation: Leaves no oily residue, reducing the risk of contamination and making it suitable for food-processing and cleanroom applications.

Parameters of Expanded graphite powder

Expanded graphite powder is a type of powdery material that has been processed to increase its hardness and improve its strength compared to pure graphite. The term "expanded" refers to the process of increasing the particle size, which allows for greater surface area and improved mechanical properties. There are several different grades of expanded graphite powder available, each with varying levels of hardness and strength. Some common grades include: * High-Crystalline Expanded Graphite (HCEG): This is the highest grade of expanded graphite powder, offering the best combination of hardness and strength. It typically ranges from 80-150 Shore A, depending on the specific recipe used. * Medium-Crystalline Expanded Graphite (MCEG): This is slightly harder than high-Crystalline Expanded Graphite but still offers good strength and durability. It typically ranges from 60-90 Shore B. * Low-Crystalline Expanded Graphite (LCEG): This is one of the softest grades of expanded graphite powder, but it offers the lowest weight per unit volume and is therefore ideal for applications where weight savings is important, such as in space transportation or aerospace components. In general, the choice of grade of expanded graphite powder will depend on the specific application and requirements of the product being produced.

Applications of Expanded graphite powder

  1. Metalworking: In high-temperature forging, stamping, and casting operations where conventional lubricants would break down.

  2. Valves and Actuators: For lubrication of valve stems and actuators in petrochemical plants and refineries, where high temperatures and corrosive conditions are prevalent.

  3. Locks and Hinges: To reduce friction and prevent freezing in outdoor locks and hinges exposed to temperature extremes and moisture.

  4. Marine Applications: On boat trailer rollers and winches, where water-resistance and corrosion protection are crucial.

  5. Automotive: Used in brake systems, engine parts, and chassis components to withstand high temperatures and heavy loads.

  6. Food Processing Equipment: Where clean, non-toxic lubrication is required to meet hygiene standards.

FAQs of Expanded graphite powder

Q: Is Expanded graphite powder conductive? A: Yes, graphite is electrically conductive. Therefore, dry graphite lubricants should be used cautiously near electrical components to avoid short circuits.

Q: How is Expanded graphite powder applied? A: It can be applied as a dry powder, brushed or sprayed on as a suspension in a carrier fluid, or as a pre-formed graphite-based coating or tape.

Q: Is Expanded graphite powder safe for the environment? A: Graphite is a naturally occurring mineral and generally considered safe when used appropriately. However, care should be taken during disposal to prevent environmental contamination.

Q: Will Expanded graphite powder attract dust or dirt? A: Though less prone than oil-based lubricants, dry graphite can still attract some dust and debris over time due to its slightly abrasive nature. Regular cleaning may be necessary.

Q: Can Expanded graphite powder lubricant be used on plastic parts? A: Yes, graphite is compatible with most plastics and can provide effective lubrication without causing degradation or damage.
