Abstract

The environment protecting water quality stabilizer consists of scale inhibitor, corrosion inhibitor, assistant compounded together, and has the features of high efficiency, low toxicity and environment friendship. The water treating agent may be used in water system to produce corrosion inhibiting and scale inhibiting dispersion effect and may be used in the conditions of high hardness, high pHand high concentration multiple. The water treating agent may be used in circulating cooling water system with calcium hardness up to 750-1300 ppm, and in make-up water calcium hardness of 120 ppm, the concentration multiple may reach 10, being in zero-exhaust level.

Description

1. Technical field [0001] The invention is an efficient and environment-friendly water treatment agent used in water systems to prevent scale, disperse and inhibit corrosion, especially the water treatment agent for circulating cooling water systems under the conditions of high concentration multiple, high hardness and high pH value. 2. Technical background [0002] The cooling water system includes heat exchangers, cooling towers, pumps and cooling water lines. During the operation of the cooling water system, the metal surfaces of the heat exchangers, pipelines, pumps, etc. that are in contact with the cooling water will have problems such as corrosion, scaling, and sludge clogging, which will affect the heat exchange efficiency of the heat exchanger and the service life of the equipment. Wait. [0003] Dirt in the cooling water system can vary from system to system. The dirt in the cooling water system generally includes calcium and magnesium carbonate, phosphate, silic...
