Abstract
Articles which require the removal of an adhering substance, such as residue of a galvanizing bath, are rinsed by spraying an aqueous rinsing agent against them repeatedly. Each spraying interval is followed by a run-off interval during which the sprayed-on rinsing agent can run off the articles. The length of the run-off intervals is equal to, or greater than, the length of the spraying intervals.
Claims9
A method of rinsing articles to remove an adhering substance, particularly subsequent to chemical or electrochemical surface treatment of the articles, comprising the steps of
- positioning an article to be rinsed in a confined space;
- spraying a rinsing agent onto the article at a pressure of between substantially 2 and 6 bar for a first period of time corresponding to between substantially 0.1 and 5 seconds to remove an adhering substance from a surface of the article with keeping the surface intact;
- terminating the spraying and allowing the rinsing agent to run off the article for a second period of time corresponding to between substantially 1 and 10 seconds and which is at least substantially equal to or greater than said first period;
- and
- repeating the spraying and terminating steps with the same time periods.
A method of rinsing articles to remove an adhering substance particularly subsequent to chemical or electrochemical surface treatment of the articles, comprising the steps of positioning an article to be rinsed in a confined space;
- spraying a rinsing agent onto the article at a pressure of 3.5 bar for a first period of 1.5 seconds to remove an adhering substance from a surface of the article with keeping the surface intact;
- terminating the spraying and allowing the rinsing agent to run off the article for a second period of 5 seconds and repeating the spraying and terminating steps with the same time periods.
