    摘要: A process for producing nonionic detergent granules having a bulk density of from 0.6 to 1.2 g/ml is disclosed, which comprises the following steps (1) to (3):(1) mixing a detergent material comprising a nonionic surfactant;(2) granulating a mixture obtained in said step (1) by agitating in an agitating mixer provided at the center position thereof with a rotation shaft having an agitation impeller with a clearance between the agitation impeller and an inner wall of the mixer, wherein the agitation impeller agitates the mixture to form an adhesion layer of said mixture on said inner wall of said mixer so as to increase a bulk density of granules of the mixture; and(3) mixing the granules obtained in said step (2) with fine particles to thereby coat the surface of the granules with the fine particles. The nonionic detergent granules containing a nonionic surfactant in a high content and having high bulk density and excellent powder fluidity and non-caking property can be produced in the process of the present invention with less suffering from restriction in the composition.

    摘要: An acidic aqueous zinc-containing coating solution containing about 0.08 to about 0.2 weight percent of zinc, about 0.8 to about 3 weight percent of phosphate, about 0.05 to about 0.35 weight percent of chlorate, about 0.001 to about 0.1 weight percent of nitrite, and a complex fluoride ion having the following concentration:0.4.gtoreq.y.gtoreq.0.63x-0.042wherein x is the concentration of the zinc in weight percent and y is the concentration of the complex fluoride ion in weight percent. The coating solution is useful for forming on metal surfaces zinc phosphate coatings that exhibit excellent alkali resistance, good adhesion to a paint film, and good corrosion resistance after painting when used as an undercoat for the cationic electrodeposition of a paint film.
