    摘要: Washing methods of deinking secondary cellulose fiber (i.e., removing unwanted non-cellulose materials therefrom) are disclosed. These washing methods (as opposed to flotation methods) generally involve deinking the fiber with surface active agent (surfactant).The present invention utilizes a single foam-suppressing surface active agent consisting essentially ofR--(Ar)--(OC.sub.2 H.sub.4)m--(OC.sub.3 H.sub.6)n--Y;wherein R represents a monovalent higher aliphatic group containing from 6 to 24 carbon atoms,Ar represents an aromatic residue,--(OC.sub.2 H.sub.4)m--being a poly(ethylene oxide) chain,--(OC.sub.3 H.sub.6)n--being a poly(propylene oxide) chain;m is about 6 to about 15,n is about 12 to about 48,m:n is less than 1, andY is selected from the group consisting of hydroxyl and benzyl ether.The present washing method of deinking reduces or eliminates objectionable foam, potentially provides energy savings yet maintains or improves the quality of the deinked fiber.

    摘要: The disclosed foamable phosphatizing compositions comprise a phosphatizing agent combined with a high-foaming surfactant. When mixed with a gas such as air, the composition provides a relatively stable foam which adheres to overhead or inclined or vertical metal surfaces. When the foam has been in place on the metal surface for a certain minimum dwell time (and the coating weight has reached at least 10mg/ft.sup.2), the phosphatizing composition is rinsed off or is permitted to drain off. By procedures which involve reproducible laboratory tests, maximum and minimum dwell times or contact times can be determined even for use in the field under poorly controlled conditions. As a result, the control over the resulting phosphate coating weights is comparable to the control obtainable in immersion techniques or tunnel sprayer techniques. This high degree of control in a foam spraying technique makes possible an efficient, economical method for spray-phosphatizing bulky three-dimensional objects or inclined or overhead surfaces, regardless of whether or not reuse of the phosphatizing composition is a realistic possibility.

    摘要: The disclosed organic ammonium phosphate salt concentrates can be diluted with water in the weight ratio of from 1:5 to 1:250 (concentrate:water) and used in bath, spray, or steam phosphatizing (sometimes called "phosphating"). These concentrates and the resulting diluted solution are reasonably pH-stable in the pH range of 3.0 to 5.5. Preferably, the concentrates contain a buffer, various surfactants, and, particularly for low temperature use (e.g. 20.degree.-55.degree. C.) an accelerator system. The concentrates are well suited to automatic dispensing of a phosphatizing spray or make-up solution (for a bath); they are efficient at low temperatures; and they have good storage stability.
