Wide uses of graphite powder in industrial industry


Graphite has good chemical stability. Specially processed graphite has the characteristics of good corrosion resistance, good thermal conductivity, low permeability and etc.. It can be used for making heat exchangers, condensers, combustion towers, absorption towers, coolers, heaters, filters and pumps. Graphite powder is widely used in petrochemical industry, hydrometallurgy, acid-base production, synthetic fiber, paper making and other industrial sectors, and it can save a lot of metal materials.

For foundry, sand scrolling, pressing die and high temperature metallurgical materials: As the thermal expansion coefficient of graphite is small, and the ability to withstand the changes of chilling and quench heat, it can be used as casting mould of the glass. Black metal gets the exact size of the castings after the graphite powder is used, with surface smooth and high yield. Metal can be used without processing or a little processing, so it can save a lot of metals.

Graphite also prevents boilers from scaling. A test of the units concerned shows that adding a certain amount of graphite powder (about 4~5 grams per ton of water) to the water can prevent scaling on the surface of the boiler. In addition, graphite is applied to metal chimneys, roofs, bridges and pipelines for corrosion protection and rust prevention. 

Graphite can be used as pencil core, pigment, and polishing agent. After special processing, graphite can produce various special materials for relevant industrial departments.

In addition, graphite powder is also used as a burnishing agent and antirust agent for glass and papermaking in light industry. It is an indispensable raw material for making pencils, ink, black paint, ink and synthetic diamond and diamond. Graphite is a good energy saving and environmental protection material. The United States has used it as a vehicle battery.  

The application field of graphite has been widening with the development of modern science & technology and industry, and has become an important raw material for new composite materials in the field of high technology. Graphite powder plays an important role in the national economy.
