PROBLEM: To provide a novel paint waste liquid treatment method that is of simple construction, may be handled with ease, is easy to operate, and has good efficiency.SOLUTION MEANS: A method of treating waste liquid containing paint associated with the present invention is characterized in that at least one of either a treatment solution or a waste liquid containing paint is atomized and supplied in droplet form to a treatment tank, and a treatment solution phase and a waste liquid phase are mixed to produce flowing material in an emulsified state (a flowing emulsion), to treat said waste liquid. The present invention makes it possible for treatment of paint waste liquid to be carried out more simply and more easily than is the case with biological waste liquid treatment techniques, and makes it possible for treatment to be carried out at sites where waste liquid is generated.SELECTED DRAWING: FIG. 1
摘要:
The particle components may be collected by using a phenomenon that the particle components in the aqueous phase aggregate at the liquid-to-liquid interface. Both of the particle components and the dissolved components in the aqueous phase may be simultaneously collected if combined with liquid-liquid extraction phenomenon that the dissolved components in the aqueous phase are collected into the solvent phase through the liquid-to-liquid interface. The aggregation phenomenon of the particle components at the liquid-to-liquid interface may be promoted by using an emulsion flow method, a method of applying mechanical external forces (such as stirring and vibrating) or another method combining both the above-mentioned methods.

摘要:
The water-based recording ink according to the present invention comprises water, a pigment, a water-soluble homopolymer and a copolymer having both a hydrophobic portion and a hydrophilic portion.The ink according to the present invention can provide a print having excellent density, light fastness and water resistance. Furthermore, the water-based recording ink has such various properties necessary for use as an ink jet recording ink that it does not clog a fine ejection nozzle, has excellent rubbing resistance and setting to dry in the print, is free from aggregation or settlement of solid matter, such as a pigment particle, and exhibits no change in the properties of the ink even when stored at a high temperature or a low temperature for a long period of time and can be redispersed by stirring or further addition of a solvent even when the pigment once aggregated.
摘要:
An electrophoretic imaging device includes an electrosensitive layer; an insulating body arranged to confront the electrosensitive layer; a developing solution filled between the electrosensitive layer and the insulating body, with the developing solution prepared by dispersing two or more kinds of electrosensitive toners into an insulating solvent; a mechanism for applying a voltage between the electrosensitive layer and the insulating body; a mechanism for irradiating a toner selection light which causes at least one kind of electrosenstivie toner to be selectively sensitizxed; and an electrosensitive layer exposing mechanism for causing image data to be photosensitively written to the electrosensitive layer. In such an electrophoretic imaging device, the electrosensitive layer is made of at least two layers, a light-shielding layer and a photoelectric charge generating layer, from a side at which the electrosensitive layer is in contact with the developing solution, and the toner selection light irradiating mechanism is provided with a filter mechanism.
