초록
산업세정제 중에서 환경친화적이라 대체 세정제로 유망한 수계세정제를 배합하고 임의 세정성을 평가하였다. 수계세정제 배합시 EO부가 몰수가 3, 5, 7인 primary alcohol ethoxylate계열의 비이온계면활성제를 주계면활성제(S)로 하고 음이온계면활성제, 알코올류 등을 보조계면활성제(A)로 하여 수계세정제를 배합하였고, 이들 배합비(A/S)에 따른 절삭유와 그리스의 혼합오염물에 대한 세정성을 평가하였다. 또한 builder인 NaOH, KOH, Na2CO3, NaHCO3를 첨가하여 세정효율 향상을 평가하였다. 세정성 평가 실험결과 보조계면활성제로는 음이온계면활성제인 Triethanolamine Lauryl Sulfate(TLS) 사용 시에 가장 세정효율이 좋았고, builder로는 NaOH, Na2CO3가 우수한 세정효율을 보여주었다.
Aqueous cleaning agents which are considered to be environmental-friendly and promising alternative ones among various industrial cleaning agents were evaluated in this words. In order to formulate aqueous cleaning agents, primary alcohol ethoxylates with 3, 5 and 7 moles of ethylene oxides among nonionic surfactants were selected as main surfactants. And anionic surfactants and alcohols were chosen as their cosurfactants. Builders such as NaOH, KOH, Na2CO3 and NaHCO3 were also evaluated as additives for improvement of cleaning efficiency of aqueous cleaning agents. The experimental results of cleaning ability tests show that introduction of anionic surfactant TLS as cosurfactant in alcohol ethoxylate-based aqueous solution gives the best cleaning efficiency for removing mixed soil of cutting oil and grease. NaOH and Na2CO3 are also shown to play an important role for improvement of cleaning efficiency in a aqueous cleaning agent.
