Product details
Cold ramming paste is a type of cathode paste that can be laid at room temperature. The aggregate of this cathode paste is the same as that of ordinary cathode paste (also known as hot ramming paste). The softening point of cold pressed paste is low and the volatile matter is high.
Physical and chemical performance indicators of cold ramming paste:
| Ash content% | Volatile matter% | True specific gravity g/cm3 | Volume density g/cm3 | Compressive strength MPa | Pore porosity% | |
| ≤6 | 8—12 | ≥1.8 | ≥1.3 | ≥12 | 25—35 |
