초록

여러 비인온성 계면활성제의 고체표면 세정성은 탄화수소의 사슬길이, EO의 부가몰수, 브랜드 및 농도의 변화에 많은 영향을 받는다. 즉 세정성은 탄화수소의 사슬길이가 감소하므로 용매화도의 증가로 향상되고, 특히 EO의 부가몰수는 장쇄탄화수소 사슬을 갖는 비이온성 계면활성제의 세정성에 중요성을 갖는다. 또한 희박한 용액에서는 EO의 부가몰수가 큰 영향을 주지 않지만 소수성부의 탄화수소 사슬의 길이에 영향을 주는 것은 계면활성제와 용매사이 상호교환에 의한 것으로 보인다. 실제적으로 C₆~C₁₀범위의 지방족 알코올인 경우 EO의 부가몰수가 약 50wt% 인 것이 세정에 가장 효율적인 상승효과를 가져왔다. 통상적인 예로 비이온성 계면활성제[A], NPEO₉ 및 NPEO₉/BC의 브랜드에 의한 세정 상승효과를 비교 검토한 결과 NPEO₉는 소수성의 알킬기가 크기 때문에 보다 낮은 분자량을 갖는 비이온성 계면활성제와 비교할 때 상대적으로 세정성이 낮은 것을 보여 주었다. 농후한 용액에서는 NPEO₉와 BC 사이의 세정상승효과를 나타내었지만 희박한 용액에서 BC첨가는 별 영향이 없다.

The solid-surface cleaning performance of various nonionic surfactants was evaluated as a function of hydrocarbon chain length, oxyethylene unit (EO) content, blending condition and concentration. Performance level increases significantly as a result of an increase in solvency capability when hydrocarbon chain length decreases. EO content is also important, particularly when nonionic surfactant with longer hydrocarbon length are used. Surfactant concentration has little effect on the optimum EO content in dilute solution but significantly affects the hydrocarbon chain length of the hydrophobic part. This is thought to be the result of a trade-off between the surfactant properties and solvency properties. Overall results show the optimal nonionic surfactant for solid-surface cleaning can be obtained when a blend of C₆~C₁₀ fatty alcohols is ethoxylated to a 50 wt% EO level. Commonly used surfactant system, e.g., nonylphenolnonaethoxylate (NPEO₉) and butyl cellosolve(BC) blends were also examined. Results show that NPEO₉ gives relatively poor performance compared with the lower molecular weight linear nonionic compounds due to the large size of its hydrophobic part. In case of concentrated solution, a synergism does exist between APE and BC, while under dilute conditions, the addition of BC in ineffective.
