| Abstract: |
| Electric calcined anthracite and pitch coke were selected as aggregates to study effects of process parameters and raw material properties on static wettability of phenolic resin and carbon aggregate. Surface functional groups and elemental occurrence forms of phenolic resin and carbon aggregate were analyzed by FT-IR and XPS. The results show that static wettability of phenolic resin to electric calcined anthracite and pitch coke rises with the increase of aggregate size, heating temperature and heating time, and rises first and drops latter with the increase of vibration times. Wettability of phenolic resin on electric calcined anthracite is affected by chemical composition, crystal structure and rheological properties of raw materials. The spread and diffusion of phenolic resin on carbon aggregate surface depends on interaction of surface functional groups including hydrogen bond, electrostatic bond, and acid-base neutralization reaction. |
