Graphite powder is natural graphite powder, after adding a certain proportion of adhesive, extrusion, made into a diameter of 2 cm stone graphite ball or graphite particles, dried in the sun or drying bags, whether it is double nylon bags or other chemical snake-skin bags, can not prevent the phenomenon of moisture return. The result is that when graphite particles are put into molten steel, numerous bubbles are formed, which affect the effect. What are the reasons that lead to the return of the graphite powder?

Some friends will be questioned, the emergence of this return to the tide may not be thoroughly dried graphite grains, how to detect out thoroughly dried. Or is thoroughly dried, how can ability put an end to return damp?

In fact, if it is pure graphite powder, it is very easy to thoroughly dry, with vacuum or inert atmosphere under the high temperature on the line, so high temperature what water is not.

If the adhesive is not resistant to high temperature, it is no problem to directly heat the graphite in the air to between 100 and 400 baking, pure graphite in the air below 500 degrees is relatively stable. If the requirements for return of moisture is high, it is best to use as soon as possible after drying, or storage when the special drying oven.

Tianshengda graphite is located in Laixi, Qingdao, the geographical position is superior, the source of the mine, to meet the needs of customers, welcome new and old friends to call for details, good after-sales service for you to escort.
