Abstract (en)

[origin: WO0129168A1] The invention concerns a cleaning composition comprising an aqueous solution containing between 0.05 to 5 wt. % of sodium metaperiodate and between 0.05 and 0.75 wt. % of sulphuric acid, and an aqueous solution of 0.5 to 90 wt. % of a mixture of dialkylesters and of 0.5 to 50 wt. % of a non-ionic surfactant. The method for cleaning a silk screen consists in exposing it to such a composition to eliminate ink, the masking product and the ghost image. The device for cleaning comprises a first section (4) wherein are a first ramp (26) of nozzles for spraying a cleaning composition on the screen (2) and a second ramp (32) of nozzles for spraying water under high pressure, and with which is associated a drain tank (20) for recovering the cleaning product and a reservoir (14) of cleaning product separate from the drain tank (20).
