Superhigh-temperature circulating water antisludging agent and application thereof
2010
The invention discloses a superhigh-temperature circulating water antisludging agent, which comprises phytic acid and polyamino polyether methylene phosphonae with the mass ratio of 1:1-20. The invention also discloses the application of the antisludging agent. The scaleinhibition capability of the antisludging agent is increased along with the temperature raise within the range of 100 DEG C, and has good scaleinhibition effect, realizes zero emission of sewage, greatly saves the circulating water, and can be applied to the difficult problems of water scaleinhibition for a blast furnace and continuous casting in a steel mill. By adopting the method of the invention to treat the high-temperature circulating water, the scaleinhibition effect is good, and the use level of the circulating water is greatly reduced.
