Abstract:
     The invention provides the prescription of two kinds of decarbidizing agents, of which one is mainly composed of dichloromethane, potassium soap, low molecular wt. aliphatic amine, non ionic or anionic surface-active agent and low molecular wt. alcohols etc., and the another is of alkaline electrolyte, potassium soap, low molecular wt. aliphatic amine, nonionic or anionic surface-active agent. The former belongs to solvent-emulsion type decarbidizing agent, while the latter ag. type. Neither of them contains phenols or benzenoid aromatic hydrocarbors. They are characterized by the merits of wide applicability and high efficiency range of decarbidizing esp. superior to those of the current decarbidizing agents during decarbidizing for mid temp. region carbon deposit.
