Graphite Suspension |
| 配方組成： |
"Carbopol" 934/0.8
Sodium Hydroxide (10% solution)/4.2
Water/149.0
Graphite No.0399/50.0 |
| 配制方法： |
Carefully disperse the "Carbopol" 934 in half the water and neutralize with the sodium hydroxide. Disperse the graphite in the remaining water and carefully stir this dispersion into the neutralized "Carbopol" 93 mucilage.
This suspension has a viscosity of 9,720 cps (Brookfield, 20 rpm) and displays no flocculation or settling on aging. It is important, however, that the mucilage be neutralized to at least pH 9 before the graphite dispersion is added, or flocculation and settling will occur. |
