| 摘要 |
The invention concerns a method of cleaning objects contaminated with fresh paint and/or varnish, using a hot paint removal agent. In order to be able to regenerate the paint removal bath economically, without significantly reducing the proportion of active substances that it contains, the invention provides regeneration of the aqueous paint removal bath by microfilitration. The bath liquid is passed, without significant cooling, across a ceramic membrane at a given minimum flow rate and a given minimum transmembranalpressure difference. The material retained by the membrane is discarded.
