What is impregnation and which carbon materials need to be impregnated?

Impregnation is the process of placing carbon materials in a pressure vessel and forcing liquid impregnant (such as bitumen, resins, low-melting metals and lubricants) to penetrate into the pores of the product under certain temperature and pressure conditions.

Carbon materials that need to be impregnated include:

(1) The joint of the graphite electrode is roasted blank;

(2) Roasting body of high-power and ultra-high-power graphite electrodes;

(3) Graphite billet with impervious graphite for chemical graphite equipment;

(4) Bad materials for some special purpose electric carbon products.
