RECYCLE METHOD FOR EXCESSIVELY SPRAYED WATER-BASE COATING |
摘要 |
<p><P>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. <P>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. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
