example 1
[0037]The following process can be utilized to form a 40 wt % AirCo 90 graphite powder, 5 wt % FORTAFIL ½ inch unsized carbon fiber, 28 wt % OXYCHEM Phenolic resin, and 27 wt % Softwood Pulp.
1. Water is mixed with the solids in a portion of 0.4 g graphite powder, 0.05 g carbon fibers, 0.28 g Oxy-Chem Phenolic Resin, and 0.27 g Softwood Pulp to form a slurry having about 1 v / o solids.
2. Once thoroughly blended, the slurry is showered onto a horizontally moving screen to form a planar sheet with a basis weight of 250 lb. / ream or 12 oz / sq.-yard, plus or minus 5%.
3. The screen is passed over a vacuum to remove some of the remaining water, and thereby partially dry the planar sheet.
4. The partially dried planar sheet is then directed over rollers and oil heated drums to volatilize residual water and form the dried paper. The drums are heated to 250° F.
5. The dried paper is spooled on a cardboard tube for collection.
6. The spooled paper is cut into 10-12 inch by 6 inch sheets.
7. The sheet...
