摘要： PROBLEM TO BE SOLVED: To provide a recycle method for a melamine resin curing type water-base coating in which a curing property is not reduced at processes for recovery and concentration and film characteristics such as hardness, a water-proof property and weather-resistance of a cured coating film are not deteriorated even in a water-base coating having rich water-solubility and containing an eluting component. SOLUTION: The recycle method for excessively sprayed water-base coating includes a step for spraying the water-base coating containing a binder component obtained by combining a polyester resin and a melamine resin onto an object to be coated; a step for capturing dust of the excessively sprayed water-base coating with booth circulation water; a step for separating a diluted coating liquid containing the captured water-base coating and the booth circulation water to a concentrated liquid and a filtrate using an ultrafilter membrane; a step for adding the reduction degree of a flowing out component passed through the ultrafilter membrane with the booth circulation water and not recovered to the concentrated liquid and compensating it; and a step for using the filtrate as the booth circulation water and using the concentrated liquid as the water-base coating.

摘要： PROBLEM TO BE SOLVED: To provide a method for adjusting booth water for forming a water curtain capable of efficiently trapping an over-sprayed paint not applied to an article to be coated when it is coated with an aqueous paint by spray coating. SOLUTION: Booth water is allowed to flow down in a film state along the wall surface of a curtain arranged at a position exceeding the article to be coated in a spray coating direction, in order to trap the over-sprayed paint not applied to the article to be coated when the article to be coated is coated with the paint by spray coating. A non-volatile hydrophilic solvent and/or a hydrophilic surfactant is allowed to be present in the composition of booth water to adjust the surface tension of booth water to 55×10-5 N/cm or less.
