Abstract
The invention belongs to the technical field of water treatment, and particularly relates to a composite corrosion inhibitor for boiler water. The composite corrosion inhibitor for boiler water is composed of the following components in parts by weight: sodium polyacrylate, benzotriazole, sulfonated polystyrene, a citric acid, and a 1-hydroxy ethylidene-1,1-diphosphonic acid. The composite corrosion inhibitor is convenient to use, small in toxicity, tasteless, and good in dispersity.
Description
Technical field
The invention belongs to the technical field of water treatment, be specifically related to a kind of composite corrosion inhibitor for feedwater.
Background technology
Feedwater plays the important and pivotal role in boiler systems, but feedwater used has certain corrosive property, and when water temperature is higher than under the various occasions of envrionment temperature, corrosion can bring serious consequence.When it can be used as medium for industrial boiler system, can water quality deterioration be caused, the problems such as corrodibility increase occur, causes boiler and pipeline leakage, have a strong impact on production equipment and normally run.Develop the progress with technology rapidly along with socioeconomic, water technology comes into one's own day by day, by using water treatment agent can effectively protection against corrosion, thus the utilization ratio of raising equipment and water and reach the object of saving water source and the energy.Increasingly strict to the water treatment standard of inhibition at present, high requirement be it is also proposed to the feature of environmental protection of additive simultaneously.
