Graphite Particle

Graphite powder is a non-metallic mineral material. Graphite powder has high
conductivity and thermal conductivity, high melting point, good lubricity,
plasticity and chemical stability. Graphite powder can be corroded by acid,
alkali and organic solvents. Therefore, it is widely used in chemical,
petroleum, metallurgy, casting, lubrication, sealing and other industrial
fields.

Graphite Particle
Graphite particles are also called graphite columns, also known as small-size
graphite rods. They are called in different ways due to different industries,
but their products are the same and need to be processed from high-purity
lubricated and conductive graphite raw material. Graphite particles have a wide
range of uses. They can be used as lubricating particles of copper guide
sleeves, self-lubricating bearing, and carburizing agents.

Advantages of adding graphite powder in steel smelting

Because of the excellent performance of graphite powder carburize, it has
become an indispensable auxiliary additive for the production of high-quality
steel in the ironmaking industry. The following are the benefits of adding
graphite powder in steel smelting:

1. Graphite powder can be used on the surface of castings in the metallurgical
industry forging industry, which is convenient for casting out and improves
casting process performance; A part of graphite powder with good heat
resistance can be made into graphite crucible for smelting metal materials.
Graphite powder can also have a unique effect in the iron-making industry.

2. Steel smelting is to smelt cast iron into steel. In order to reduce the
application of cast iron raw materials and the cost of steel smelting, it is
necessary to add the carburize with graphite powder as the main raw material in
steel processing.

3.Graphite powder carburizing agent has the characteristics of high fixed
carbon content, heat resistance, smooth moistening performance, and easy
absorption. It is added to the surface of molten iron according to a certain
proportion. According to the vortex mixing of mechanical equipment or manual
service mixing, it can digest and absorb the appropriate carbon in graphite
powder carburizing agent, reduce sulfur and other residual components in steel,
improve the quality of steel and reduce the cost of casting products, Improve
economic efficiency.

Application of graphite powder in coating industry

Graphite powder is widely used as coatings in the industry. Many coatings can
change the properties of coatings by adding graphite powder.

1. Graphite powder is used as anticorrosive material.

As an anticorrosive material, the antirust primer made of carbon black, talc
powder, and oil has good chemical and solvent corrosion resistance; If zinc
yellow and other chemical pigments are added into the formula, the antirust
effect is better. And has a strong corrosion resistance!

2. Graphite powder is used as a fireproof coating.

Expandable graphite is a kind of graphite intercalation compound obtained by
chemical or electrochemical treatment with natural graphite flakes as raw
materials. Under the condition of the heating, the volume of expandable
graphite expands rapidly (up to 300 times) to suffocate the flame. At the same
time, it forms expansions, which can isolate the flame and delay or interrupt
the flame spread. Moreover, it is nonflammable, has good softness, high surface
energy, and good strength of the carbonized layer. But the volume and dosage of
the expansion body should be selected appropriately.

3. The difference between graphite powder and iron powder

Graphite powder is black, it is very similar to iron powder in appearance, it
is difficult to distinguish the two.

Graphite powder and iron powder can be distinguished by physical and chemical
methods.

Physical methods distinguish graphite powder from iron powder.
1. Can take the method of touch, graphite powder is greasy, iron powder is not.

2. Iron powder can be attracted by a magnet, but graphite powder can't.

3. When heated, the iron powder turns black and the graphite powder is ignited
in the air.

Graphite powder and iron powder can be distinguished by chemical methods.
1. Distinguish by chemical method, add dilute hydrochloric acid or dilute
sulfuric acid, there are bubbles for iron powder.

2. After mixing with copper oxide and heating, adding graphite powder can
produce CO2 which makes clear lime water turbid, while iron powder does not.

To sum up, it is the difference between graphite powder and iron powder.
