| titleOfInvention | Process for cleaning electronic parts or precision parts |
| abstract | Disclosed is a process for cleaning electronic parts or precision parts which comprises the steps of: washing the parts with a cleaning agent composition, rinsing the washed parts with water having a temperature of from 5° to 100° C., and maintaining the rinsing waste water at a temperature of 20° C. or higher to effect separation of organic substances. The cleaning agent composition contains, as active cleaning components, a nonionic surface active agent and a compound selected from the group consisting of hydrocarbon compounds and slightly water soluble alkyl esters or alkyl ketones. The composition is such that 50% by weight or more of the organic substances separate from the water phase when the composition is made into an aqueous solution having an organic substance content of 5% by weight adjusted by diluting it with water or by evaporating water from it and the resulting cleaning agent aqueous solution is subsequently allowed to stand still for 30 minutes at a temperature of from 20° to 100° C. n According to the present invention, organic substances in rinsing waste water can be separated and removed efficiently, and subsequent waste water treatment step can be simplified. The process is economically advantageous, because the rinsing waste water after the separation treatment can be used again as a rinsing liquid. |
