The Complex Formulation and Performance Research of a New Stopped-Boiler Protectant
In this paper, octadecylamine (ODA), dimethyl oxime and bromogeramine are selected to complex as a filming amine (FA). Static metal hanging slice test at low temperature is used to study the inhibition performances of the FA. And the influence of the ratio for each component in FA to the properties of the film is studied. Drip method using CuSO4 solution, water droplets test method are employed to evaluate the quality of the film. Electrochemical methods are used to research the form mechanism of protective film. The results show that when each concentrations of ODA, dimethyl oxime and bromogeramine is 50 mg/L, 300 mg/L and 50 mg/L, the effect of the corrosion inhibit is the best, the time of the color change of the film in CuSO4 solution is longer than 10s, water droplets could not be spread on the film, and anti-corrosion mechanism of FA is that a hydrophobic organic molecules layer on metal surface is generated to achieve the purpose of anti-corrosion.
