Abstract

The tracing water quality stabilizer consists of scale retardant, corrosion inhibitor, tracing polymer, assistant, etc. and has the features of high efficiency, low toxicity and tracing. The tracing water quality stabilizer is used as water processing agent in water system to inhibit corrosion, retard scale and disperse, and may be used in the conditions of high water hardness, high pH value and high concentration multiple. It may be combined with relevant detecting and controlling instrument to realize the automatic detection and control of chemical concentration and automatic throwing of chemical. The tracing polymer as one of the corrosion retarding and scale inhibiting components can indicate the effective concentration of the composite chemical accurately.

Description

1. Technical field [0001] The invention is a high-efficiency tracer water treatment agent used in water systems for scale inhibition, dispersion and corrosion inhibition, 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, silicat...
