Abstract

The invention discloses a low-alkaline low foam oil-removing technology for metal piece, an oil removing agent comprises the following components: 30g/L sodium sulfate, 9.5g/L sodium tripolyphosphate, 6.5g/L of complex, 5g/L sodium dodecyl benzene sulfonate, 10g/L of OP-10, and 0.1g/L of antifoaming agent. The oil removing agent is coated on the surface of the piece and stayed for 20-30 minutes, condensed water is used for flushing the metal piece until PH value is neutral. The oil removing treatment is carried out under normal temperature, operation is simple and convenient, oil removing efficiency is high, environmental protection is realized, and production cost is low.

Description
