Abstract

본 발명에 따르면, 본 용액은 헵탄산의 수용성 염 및 산화제 및 바람직하게는 습윤제를 함유한다.According to the invention, the solution contains a water soluble salt of heptanoic acid and an oxidizing agent and preferably a wetting agent.

상기 화합물을 배합함으로써, 저농도이면서 충분히 만족스럽게 부식을 방지하고, (처리된 시이트상에) 외관상 두껍지 않은 표면을 유지하고 용액의 유출물 처리가 용이(또는 연속적인 탈지 유출수의 처리)하도록 할 수 있다.By blending the compounds, it is possible to prevent corrosion at low concentrations and sufficiently satisfactorily, to maintain an apparently non-thick surface (on the treated sheet) and to facilitate the effluent treatment of the solution (or the treatment of continuous degreasing effluent). .
