Abstract

To prepare alkaline degreasing agents(SADAs), tetrasodium pyrophosphate(TSPP), $Na_2CO_3$, Tetronix T-701 (T-701), Na-dioctyl sulfosuccinate(303C), Demol C, and MJU-100A were blended. The prepared degreasing agents were tested with steel specimens and the results were as follows. The degreasing powers of SADA-6($Na_2CO_3$ 50g/TSPP 25g/T-701 10g/303C 15g/Demol C 12g/MJU-100A 8g/water 130g mixture) for press-rust preventing oil were 98% and 99% degreasing at 4wt%, 70 $^{\circ}C$ and 90 $^{\circ}C$, respectively; for quenching oil, the degreasing power of SADA-6 was 92% degreasing at 4wt% and 70 $^{\circ}C$. From these results, it was proved that the SADA-6 exhibits a good degreasing power. Foam heights measured immediately after foaming by Ross & Miles method and Ross & Clark method at 6wt% and 60 $^{\circ}C$ were 16mm and 40mm, respectively. SADA-6 was proved a good low foaming degreasing agent.
