Abstract
The invention discloses a scale and corrosion inhibitor composition with relatively low phosphorus content, which is special for high-alkalinity and high-hardness water. The composition comprises fatty alcohol-polyoxyethylene ether carboxylate, an organic phosphine scale and corrosion inhibitor, zinc salt and the balance of deionized water. The scale and corrosion inhibitor can be used for a cooling water system with high pH value, alkalinity, hardness and concentration multiple, and has a good corrosion inhibition effect on carbon steel.
Description
Technical field
The invention belongs to water treatment agent field, provide a kind of for high alkalinity, high hardness water anti-incrustation corrosion inhibitor.
Background technology
Water loss is high, and repeating utilization factor is low, is that industrial system utilizes one of water resources large drawback, and especially for the country of the such water resources shortage per capita of China, the in short supply of water resources seriously will restrict expanding economy.As everyone knows, by adding anti-incrustation corrosion inhibitor in cooling water system, controlling the fouling corrosion problem of water system, reaching the recycle of recirculated water, and be one of industrial circle main method of economizing on water by the cycles of concentration improving recirculated water.In the operational management of industrial circulating water system, cycles of concentration is the important technology index judging cooling water circulation utilization ratio, realizes the developing direction that high concentration multiple operation is circulating water cooling treatment.At present, the water treatment agent adopted both at home and abroad is mostly organic phosphine series medicament.Generally, this serial medicament can make the cycles of concentration of recirculated water improve between 2-3, higher by only 4, causes a large amount of wastes of water resources.In recent years, along with the exploitation of high-performance Water Treatment Chemicals, the exploitation of high concentration multiple Cycle Cool Water Treatment has become the focus of enterprises pay attention.In view of the short situation of China's water resources, many mainstay industries, industry and enterprise all urgently propose the requirement of increasing income and decreasing expenditure to water resources, therefore, research and development industrial circulating water high concentration multiple runs process complete set technology, by setting up demonstration project, practice and extension in industrial circle, will the favourable situation alleviating China's water supply gets.The problem that existing scale inhibition agent ubiquity is too poor to the corrosion mitigating effect of carbon steel, can not reach the national standard requirement of corrosion of carbon steel rate.
The present invention seeks to solve recirculated water fouling difficult problem under the hard high-alkali state of height, this product, primarily of organic phospho acid, aliphatic alcohol polyethenoxy ether carboxylate, zinc salt composition, is applicable to calcium hardness and basicity in recirculated water and requires to reach the recirculating cooling water system of the high concentration ratio of 1500 mg/L.
