초록

POE(6)-2-ethylhexyl ether(PEH-6), Newpol PE-68(PE-68),Na₂CO₃, tetrasodium pyrophosphate(TSPP), Demol C 및 MJU-l00A를 블렌딩하여 알칼리탈지제(DA)를 제조하였다. 철강 시료편에 DA를 처리하여 탈지력을 시험해 본 결과 DA-6(PEH-645g/PE-68 45g/Na₂CO₃ 120g/TSPP 60g/Demol C 15g/MJU-l00A 15g/Water 300g mixture)의 농도 4wt%일 때 70℃와 90℃에서의 프레스방청유 부착물에 대한 탈지율은 각각 94%와 96%였고, 70℃에서의 소입유 부착물에 대한 탈지율은 94%로 나타나 DA-6은 양호한 탈지력을 보여주었다. 또한 DA-6 농도 6wt%, 60℃에서의 Ross & Miles법에 의한 기포력 측정결과, 조작 1분 후의 포고가 8mm와 77mm로 각각 나타나 DA-6은 양호한 저기포성 탈지제임이 입중되었다.

Alkaline degreasing agent(DA) was prepared by blending of POE(6)-2-ethylhexyl ether(PEH-6), Newpol PE-68(PE-68), Na₂CO₃, tetrasodium pyrophosphate(TSPP), Demol C, and MJU-l00A. The degreasing power of DA's was tested with steel specimens and the results are the following : A solution of 4wt% DA-6(PEH-645g/PE-68 45g/Na₂CO₃ 120g/TSPP 60g/Demol C 15g/MJU-l00A 15g/Water 300g mixture) shows 94% and 96% of degreasing power for press-rust preventing oil at 70℃ and 90℃ respectively, and 94% for quenching oil at 70℃. The test results show that DA-6 was a better degreasing agent. Foam heights measured after 1minute by Rose & Miles method and Rose & Clark method at 6wt%, 60℃ were 8mm and 77mm, respectively. As the result, DA-6 was proven to be a good, low-foaming, degreasing agent.
