Abstract
The invention belongs to the technical field of water treatment and in particular relates to a corrosion and scale inhibitor used for circulating cooling water. The corrosion and scale inhibitor comprises the following components in parts by weight: amino trimethylene phosphonic acid, tartaric acid, copper sulfate, sodium metabisulfite and potassium nitrate. The corrosion and scale inhibitor is convenient to use, has low toxicity, is tasteless and has good dispersibility.
Description
Technical field
The invention belongs to the technical field of water treatment, be specifically related to a kind of corrosion inhibiting and descaling agent for recirculated cooling water.
Background technology
Recirculated cooling water plays the important and pivotal role in a cooling system, but recirculated cooling water intensity used is high, basicity is large, have serious scale feature, when water temperature is higher than under the various occasions of envrionment temperature, the fouling of the inorganic salt such as calcium carbonate can bring serious consequence.When it can be used as heat-eliminating medium for industrial cooling circulating water system, can water quality deterioration be caused, the problem such as corrosion and scaling occurs, cause heat exchanger and line clogging or 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 and prevent fouling, 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 corrosion-mitigation scale-inhibition at present, high requirement be it is also proposed to the feature of environmental protection of additive simultaneously.
