Composite water treating agent for central air conditioner cooling water

Abstract

The invention discloses a treating agent of cooling water and composite water in central air-conditioning, including the weight or portioning components listed as following: one to ten portion of epoxy succinic acid; one to ten portion of phosphonate; one to ten portion of molybdate calculated according to molybdic acid ion; 0.1 to ten portion of rare-earth element salts; one to five portion of copper inhibitor; zero to three portion of zinc calculated according to zinc ion. This invention is low-phosphorus and environment-friendly type, good quality in antisludging and corrosion inhibit, easy to obtain material, explore the application area of using rare-earth element in water treatment, and have greatly active meaning in developing rare earth project of our country.

Description

technical field

[0001] The invention relates to a composite water treatment agent, in particular to a composite water treatment agent for central air-conditioning cooling water. Background technique

[0002] In the central air-conditioning water system, due to the combined effect of the evaporation and concentration of circulating cooling water, the entry of dust and debris, as well as the equipment structure and materials, the entire system will produce corrosion and scaling, especially corrosion problems, which will affect The service life of the equipment and the heat exchange efficiency will cause energy waste, which will seriously cause the high-voltage operation and tripping of the air conditioner host. Therefore, it is necessary to add effective water treatment chemicals to the cooling water of the central air conditioner. The most widely used corrosion and scale inhibitors in the current circulating cooling water system are organic phosphine series composite water st...
