Abstract

The invention relates to a low-phosphorus corrosion / scale inhibitor for circulating cooling water, which is compounded from a carboxylic acid polymer, a nitrogen heterocyclic ring compound, an organic phosphorous compound, an auxiliary corrosion inhibitor, a bactericide and deionized water. The low-phosphorus corrosion / scale inhibitor for circulating cooling water can decelerate corrosion of metals and deposition of inorganic scales on the exchange surface in the heat exchanger furnace, has favorable corrosion / scale inhibition properties, has bactericidal action, has low phosphorus content, conforms to the national environment-friendly industry policy, and can be widely used in various types of circulating cooling water.

Description

technical field [0001] The invention relates to a circulating cooling water treatment agent, in particular to a circulating cooling water treatment agent with multiple functions of corrosion inhibition, scale inhibition and sterilization for circulating cooling water. Background technique [0002] With the rapid development of industry, the shortage of water resources and water pollution have become more and more serious, which has constituted a serious social crisis [1]. Cooling water accounts for more than 80% of industrial water. At present, the use of chemical dosing treatment is the most effective and economical technical measure in the treatment of circulating water quality stabilization, that is, according to the water quality and material characteristics of the circulating cooling water system, the appropriate water quality stabilizer To control system fouling, corrosion, bacteria and algae growth and other problems. [0003] Circulating cooling water has certain pa...
