Graphite-Oil Mold Release |
| 配方組成： |
"Carbopol" 941/0.25
Mineral oil/50.00
Sodium hydroxide (10% solution)/1.40
Graphite 5XX/25.00
Water/50.00
"Ethomeen" C-25/0.25 |
| 配制方法： |
Carefully disperse the Carbopol 941 in the water. After complete dispersion, add the sodium hydroxide and then the Ethomeen C-25. next, disperse the graphite in the mineral oil. It is advisable to deaerate this mix before the next step because of the large amount of air adsorbed on the graphite particles. Lastly, thoroughly mix in the oil-graphite blend. Stir to uniformity. The finished suspension-emulsion has a viscosity of 33,000 cps (Brookfield, 20 rpm) and a pH of 10.2. |
