EQUIPMENT PROTECTIVE AGENT COMPOSITION FOR AIRTIGHT HEATING SYSTEM

摘要

PURPOSE: Provided is an equipment protective agent composition for an airtight heating system, which protects components of the airtight heating system more excellently than conventional phosphate-base pipe cleaning agent, extends the life span of the system and prevents a shrinkage in heat efficiency. CONSTITUTION: The composition is composed of nitrite 5-10wt%, molybdate 5-10wt%, acrylate polymer 0.1-1.0wt%, azole 1-5wt% and water 74-88.9wt%. The acrylate polymer is represented by formula 1, wherein n is 10000 to 20000 and R is represented by formula 2. The composition is in a range of pH 9-11.
