Furthermore, at least one loading means may be provided in order to load the receiving device with a loading agent, which may at least delay a deposition of disposal agent on or in the receiving device.

A method for treating a wet-painting booth circulation water, includes, into somewhere along a path for a wet-painting booth circulation water supplied from a water tank to a painting booth for collecting an unapplied paint and then returned to the water tank, adding a treatment agent to a wet-painting booth circulation water so as to detackify the unapplied paint collected in the circulation water, wherein the treatment agent includes a cellulose acetate solution.

A non-aqueous solvent composition comprising 0 to 10 wt. % of N-alkyl pyrrolidone, 0 to 5 wt. % of dimethyl sulfoxide, 10 to 50 wt. % of -butyrolactone, 10 to 50 wt. % of at least one monoalcohol, 10 to 60 wt. % of at least one organic solvent inert towards isocyanate groups, other than -butyrolactone, other than N-alkyl pyrrolidone, and consisting of carbon, hydrogen, oxygen and, optionally, nitrogen, and 0 to 10 wt. % of at least one additive. The non-aqueous solvent composition can be used as barrier liquid within a coating installation of an industrial mass production coating line for the application of water-borne two-component polyurethane coatings.

The present disclosure provides stable, low chloride paint detackifier compositions. Also disclosed are methods of making the paint detackifier compositions and methods of using the paint detackifier compositions. The detakifier may be made from cationized starch and sodium aluminate. The starch can be wheat starch, corn starch, tapioca starch, potato starch, rice starch, sweet potato starch, sago starch, mung bean starch, arrowroot starch, and any combination thereof.

Disclosed is an ink set including: an inkjet pretreatment liquid containing an aggregating agent; an inkjet ink; and a cleaning liquid that contains water, a water-soluble organic solvent, a surfactant with an HLB value of 10 or more, and a metal salt A, and has a conductivity of 0.10 to 3.0 mS/cm at 5? C. A method for producing a printed textile item is also disclosed.

To efficiently perform an adhesion reduction treatment of water that circulates through a wet paint booth which contains a solvent-based paint by adding a relatively small amount of chemical to the water without the need for another chemical except that the alkaline chemical is used for pH adjustment, that is, with only one chemical. An aluminum salt having a basicity of 60% or more and an alkaline chemical are added to water that circulates through a wet paint booth which contains a solvent-based paint. An adhesion reduction treatment of the solvent-based paint is performed at a pH of 7 or more and is preferably performed at a pH of 7.5 or more. Using a powder mixture produced by mixing a powder of the aluminum salt with a powder of the alkaline chemical facilitates the treatment.

A method for operating a surface treatment installation wherein overspray that occurs in one or more coating booths is taken up by a booth air stream. Booth air laden with overspray is conducted to at least one separating unit in which overspray is separated out. The booth air laden with overspray or the booth air free of overspray is fed a solidifying material on its flow path to at least one separating unit and/or the booth air laden with overspray or the booth air free of overspray is fed a solidifying material in the interior of at least one separating unit and/or overspray that has already been deposited in at least one separating unit is fed a solidifying material and/or the at least one separating unit is fed a solidifying material before the separating unit is functionally fitted in the surface treatment installation, wherein the solidifying material has the effect that a curing process in the overspray is initiated or assisted. A device for separating out overspray from the booth air laden with overspray of surface treatment installations. Booth air laden with overspray can be passed through at least one separating unit, in which overspray is deposited. There is a solidifying material feeding device, by means of which the booth air laden with overspray can be fed a solidifying material on its flow path to at least one separating unit and/or the booth air laden with overspray can be fed a solidifying material in the interior of at least one separating unit and/or overspray that has already been deposited in at least one separating unit can be fed a solidifying material, wherein the solidifying material has the effect that a curing process in the overspray is initiated or assisted.

The invention relates to the use of a water-based carrier medium for wet scrubbing paint overspray from the circulating air in painting booths, the carrier medium containing at least 40 wt. % of polyfunctional organic oxo compounds. The carrier medium is characterized in that the viscosity thereof is within a specified range over a wide range of shear stresses, such that the carrier medium flows off of the separating surfaces of a wet scrubbing facility in a temporally homogeneous and approximately laminar manner. In a further aspect, the invention relates to a method for wet scrubbing using the aforementioned carrier medium.
