| 配制方法： |
Disperse the "Carbopol" 934 in the water with moderate mixing and neutralize to pH 9.5 with ammonium hydroxide. Slowly add the latex to this preneutralized "Carbopol" 934 mucilage with moderate mixing, such as with a Lightnin' propeller type mixer. Add the pigment, very slowly, with moderate agitation and stir until the product is smooth.
Note: An important step for the successful preparation of this product is that the "Carbopol" 934 solution must be neutralized to a pH of 9-9.5 before the latex is added. A lower pH will cause coagulation of the rubber and/or flocculation of the pigments. |
