What Are The Characteristics Of Medium-coarse Graphite Products

(1) High temperature resistance

The melting point of graphite is 3850±50°. Even if it is 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 as the temperature increases. At 2000°C, the strength of graphite doubles.

(2) Electrical and thermal conductivity

The electrical conductivity of graphite is 100 times higher than that of ordinary non-metallic minerals. Thermal conductivity exceeds that of steel, iron, lead and other metal materials. The thermal conductivity decreases as the temperature increases, and even at extremely high temperatures, graphite becomes a thermal insulator. Graphite can conduct electricity because each carbon atom in graphite only forms 3 covalent bonds with other carbon atoms, and each carbon atom still retains 1 free electron to transmit charge.

(3) Lubricity

The lubrication performance of graphite depends on the size of graphite flakes. The larger the flakes, the smaller the friction coefficient and the better the lubrication performance.

(4) Chemical stability

Graphite has good chemical stability at room temperature and is resistant to acid, alkali and organic solvent corrosion.

Characteristics of graphite products:

1. Graphite products have good adsorption properties.

The hollow structure of carbon makes carbon have good adsorption properties, so carbon is often used as an adsorption material to absorb moisture, odors, etc.

2. Graphite products have good thermal conductivity, fast heat transfer, uniform heating, and save fuel.

Baking pans and pots made of graphite heat up quickly, and the cooked food is evenly heated and cooked from the inside out. The heating time is short. It not only has a pure taste, but also locks in the original nutrition of the food.

3. Graphite products are chemically stable.

Wanmo has good chemical stability at room temperature and is not corroded by any strong acid, strong alkali and organic solvent. Therefore, graphite products consume very little even if they are used for a long time. They only need to be scrubbed and cleaned to still look like new.
