Many people think that graphite powder is carbon powder. In fact, there is still a big difference between graphite powder and carbon powder. Next, SAT NANO will introduce the difference between the two in detail;

Toner generally refers to toner, which is widely used in printer cartridges. The main component of toner (also known as toner) is not carbon, but most of it is composed of resin and carbon black, charge agent, magnetic powder, etc. The carbon powder is melted into the paper fiber at high temperature, and the resin is oxidized into a gas with a pungent odor. This is what everyone calls ‘ozone’. This gas has only one benefit, which is to protect the earth and reduce the harm of solar radiation. It is not good for the human body itself, it can cause irritation to the human mucosa, easily increase the incidence of asthma or nose allergies, and even dizziness and vomiting. Nowadays, many printer toner cartridges use toner. After the original toner is used up, many toner cartridges can be refilled by users and used again. Therefore, separate toners are sold on the market. By adding toner by yourself, the cost of consumables will be greatly reduced. Since the toner cartridge is a sealed disposable consumable, adding toner by yourself will damage the sealing performance of the toner cartridge and cause toner leakage. The toner particles are generally measured in micrometers. If they are scattered in the air, they are invisible, which will cause the use of Pollution of the environment and office environment has led to an increase in PM2.5. Graphite powder is soft and dark gray; it has a greasy feel and can stain paper. The hardness is 1-2, and the hardness can increase to 3-5 with the increase of impurities in the vertical direction. The specific gravity is from 1.9 to 2.3. Under the condition of isolating oxygen, its melting point is above 3000℃, which is one of the most temperature-resistant minerals. The chemical properties of graphite powder are relatively stable at room temperature, and are insoluble in water, dilute acid, dilute alkali and organic solvents; the material has high temperature resistance and conductivity, and can be used as refractory materials, conductive materials, and wear-resistant lubricating materials.

Graphite powder and carbon powder belong to carbon, graphite belongs to crystalline elemental carbon

Graphite powder has the following special properties:

1. High temperature resistant type: The melting point of graphite is 3850±50℃, and the boiling point is 4250℃. Even if burned by ultra-high temperature arc, the weight loss is very small, and the thermal expansion coefficient is also very small. The strength of graphite increases with the increase of temperature. At 2000°C, the strength of graphite doubles.

2. Electrical and thermal conductivity: The electrical conductivity of graphite is one hundred times higher than that of general non-metallic minerals. Thermal conductivity exceeds that of metal materials such as steel, iron, and lead. The thermal conductivity decreases with increasing temperature, and even at extremely high temperatures, graphite becomes an insulator.

3. Lubricity: The lubricating performance of graphite depends on the size of the graphite flakes. The larger the flakes, the smaller the friction coefficient and the better the lubricating performance.

4. Chemical stability: Graphite has good chemical stability at room temperature, and can resist acid, alkali and organic solvent corrosion.

5. Plasticity: Graphite has good toughness and can be connected into very thin sheets. 6. Thermal shock resistance: Graphite can withstand drastic changes in temperature without being damaged when used at room temperature. When the temperature changes suddenly, the volume of graphite will not change much and no cracks will occur.
