Tar Emulsion |
配方组成: |
Sodium Hydroxide (10% sol'n.)/0.250 "RT-8" Tar/50.000 "Ethomeen" C/25/0.063 "Carbopol" 941/0.125 Water/50.000 |
配制方法: |
Carefully disperse the "Carbopol" 941 resin in the water. When dispersion is complete, add the sodium hydroxide and then the amine. Slowly add the "RT-8" tar in a thin, continuous steam (so that the rate of addition is no greater than the rate of dispersion) with good mixing. Note: Fairly high shear such as that provided by a medium-speed Eppenbach homogenizer, forms the best, smallest droplet-size emulsion. Excessively rapid addition of the tar results in a grainy emulsion. |
