Abstract

PURPOSE: To titled preventing agent, containing a hydrazine (salt), an anticorrosive agent and a scale preventing agent, very effective for controlling slimes by the continuous addition of the hydrazine at a low concentration, and capable of treating easily the damage to a service water system only one agent mixed with the anticorrosive agent, etc.
CONSTITUTION: Hydrazine (salt) is mixed with an anticorrosive agent and/or scale preventing agent, preferably an anticorrosive agent for steel and/or polymerizable phosphate salt, phosphonic acid (watersoluble salt), etc. and an azole compound as an anticorrosive agent for copper, to give the aimed preventing agent as one agent. In solidifying the preventing agent, zinc hydrazine sulfate is preferred as the slightly soluble hydrazine, and calcium salt of phosphonic acid and the azole compound are preferred as the slightly soluble anticorrosive agent and/or scale preventing agent.
USE: The liquid type is suitable for the treatment of cooling water systems in large- scale plants, and the solid type is suirable for the treatment of slamm- sized cooling water systems for air conditioning, cooling and heating in buildings, etc.
