Abstract
The invention belongs to the technical field of water processing, and specifically relates to a composite anti-corrosion scale inhibitor for circulating cooling water. The composite anti-corrosion scale inhibitor for circulating cooling water is composed of the following components: sodium silicate, tannin, polymaleic anhydride, methoxyl propylanmine, and amino trimethylene phosphonic acid, and has the advantages of user-friendliness, little toxicity, no odor, and good dispersibility.
Description
Technical field
The invention belongs to the technical field of water treatment, be specifically related to a kind of composite slow-corrosion scale resistor for recirculated cooling water.
Background technology
Recirculated cooling water plays the important and pivotal role in cooling system, but recirculated cooling water intensity used is high, basicity is large, have serious scale feature, under the various occasions of water temperature higher than envrionment temperature, the fouling meeting of the inorganic salt such as calcium carbonate brings serious consequence.While being used for industrial cooling circulating water system using it as heat-eliminating medium, can cause water quality deterioration, the problems such as corrosion and scaling occur, cause heat exchanger and line clogging or leakage, have a strong impact on production equipment and normally move.Along with the socioeconomic progress developing rapidly with technology, water technology comes into one's own day by day, by using effectively protection against corrosion and prevent fouling of water treatment agent, thus the utilization ratio of raising equipment and water and reach the object of saving water source and the energy.At present increasingly strict to the water treatment standard of corrosion-mitigation scale-inhibition, the feature of environmental protection of additive has also been proposed to high requirement simultaneously.
Summary of the invention
The object of the invention is to for the defect of above-mentioned existence and a kind of composite slow-corrosion scale resistor for recirculated cooling water is provided, this composite slow-corrosion scale resistor is easy to use, and toxicity is little, and tasteless dispersing property is good.
Technical scheme of the present invention is: a kind of composite slow-corrosion scale resistor for recirculated cooling water, is comprised of the component of following weight part:
