the cellulose gum (CMC) and dyes are dissolved with agitation in approximately 66 lb of water. The white pigment (TiO2), the abrasives, and the bentonite are dispersed with agitation in approximately 226 lb of water to form a slurry. This is termed "thick slurry." The wax is dissolved in the solvents and the emulsifying agent is dispersed therein. To this mixture, a "thinned" slurry (prepared by adding 12 lb of water to 81.5 lb of the "thick slurry") is added slowly with vigorous agitation over a period of about 5 minutes. At the end of this period of time, the mixture assumes the appearance of a stiff paste. Agitation is continued at this stage for 15-16 minutes longer.
(Inversion will have taken place, after passing through an "oatmeal" phase.) Then the rest of the "thick slurry" is added, slowly or rapidly, with agitation. This is followed by the solution of cellulose gum and dyes. The remaining water (7 lb) is used to rinse the containers into the mixture.
When a uniform paste results, the ammon |
