Wall Paper Remover |
| 配方组成： |
"Triton" X-100 (nonionic wetting agent)/10.0
"Carbopol" 934/0.5
Water/85.0
Sodium hydroxide (10% solution)/2.1 |
| 配制方法： |
Carefully disperse the Carbopol 934 in the water. After the foam has broken, carefully mix in the Triton X-100. Lastly, add the sodium hydroxide, mixing carefully to avoid foaming.
The amount of Carbopol 934 can be altered to vary consistency. Merely maintain the 10% sodium hydroxide at a ratio of 4.2 pounds per pound of Carbopol. The foregoing formulation will give a viscosity of 14,000 cps (Brookfield, 20 rpm and a pH of 7. Its viscosity is high enough to prevent running of the remover when applied to the wall, yet not so viscous that the water and wetting agent penetration into the paper is retarded. |
