Abstract

The invention belongs to the field of water treatment and in particular relates to a composition used for water systems as well as a preparation method and using method thereof. The composition used for water systems can achieve the function of preventing scaling, corrosion and water loss and the function of preventing rusting after the water systems are out of service, can also achieve the effect of reducing equipment input and is energy-saving, efficient and environment-friendly.

Description

technical field [0001] The invention belongs to the field of water treatment. In particular, the present invention relates to a composition for use in water systems, a method for its preparation and a method for its use. Background technique [0002] Most of the heating and supplementary water in the heating system is untreated tap water. Under normal temperature conditions, steel will be severely corroded in tap water. When the water temperature is heated to 60-90°C, scaling will occur. Usually, after a heating period, there will be scaling and corrosion in different degrees in the heat exchangers, pipes and radiators of the heat exchange station, as well as in the pipes of users. Thermal fluid resistance affects heat transfer efficiency, shortens the service life of heating facilities, increases maintenance costs, and greatly reduces heating effects. [0003] For heating units, in order to achieve the purpose of energy saving and water saving, it is necessary to prevent ...
