    摘要: A heat exchange inhibitor composition, characterized in that phosphates, amine salts, silicates, borates or nitrites are not necessary, and further characterized in that p-tert butyl benzoic acid and/or an alkali salt or salts thereof and a triazole are contained therein, which provides improved inhibitive abilities against metal corrosion, glycol oxidation and plugging of the circulation passages of a heat exchange system and further provides improved stability in hard water without forming chemical depositions and does not produce nitrosamines or form gel with other salts in the heat exchange fluid.
