Multifunctional corrosion and scale inhibitor

Abstract

The invention discloses a multifunctional corrosion and scale inhibitor. The multifunctional corrosion and scale inhibitor comprises the following components in percentage by mass: 5-20 percent of phosphate and 5-15 percent of sulfonate. According to the multifunctional and multi-purpose composite corrosion and scale inhibitor, indexes such as the content of gambogic acid salt content, active components, solid contents, density, a pH value and the like meet the standard of the composite corrosion and scale inhibitor which is formulated by a state power and petrochemical system. The multifunctional corrosion and scale inhibitor is suitable for a water treatment agent of various water treatment systems requiring various kinds of water qualities, and can be directly added into the water treatment system to realize functions of scale inhibition, scale removal, corrosion inhibition, high concentration ratio and the like, so that the idea that the scale is removed if the scale exists and is prevented if the scale is absence once people uses the corrosion and scale inhibitor is realized, and on the basis of no scaling and no corrosion, the concentration ratio of the circulating water is improved, and the using amount of water is reduced; the multifunctional corrosion and scale inhibition is easy to produce, convenient to use and low in cost.

Description

technical field [0001] The invention relates to a multifunctional scale and corrosion inhibitor and a preparation method thereof, which is used as a multifunctional scale and corrosion inhibitor for industrial circulating cooling water, heating network systems and low-pressure boilers. Background technique [0002] At present, people need to deal with scaling of industrial circulating cooling water system, heating network system and boiler water under the condition of shutting down and stopping production. The descaling of the former two requires acid cleaning, which not only affects normal production The corrosion of the equipment itself is caused, and the boiler is treated by adding alkali to soften the scale. It not only has a certain degree of corrosion, but sometimes it needs to be manually hammered and smashed with a shovel to remove it, which is time-consuming and laborious. In addition, in the existing water treatment agents, different treatment agents are used to re...

Problems solved by technology

[0002] At present, people need to deal with scaling of industrial circulating cooling water system, heating network system and boiler water under the condition of shutting down and stopping production. The descaling of the former two requires acid cleaning, which not only affects normal production Corrosion of the equipment itself is caused, and the boiler is treated with alkali to soften the scale, which not only has a certain degree of corrosion, but sometimes requires manual hammering and shoveling to remove it, which is time-consuming and laborious

In addition, in the existing water treatment agents, different treatment agents are used to remove scale in different systems, and the functions are single, such as: those with anti-scaling functions have no anti-scaling functions, and those with anti-scaling functions have no anti-scaling functions. Those used in cooling water cannot be used in heating networks or low-pressure boilers, those used in surface water cannot be used in groundwater, those used in high alkali and high hard water cannot be used in negative hard water, and those used in low concentration ratios cannot be used in high concentration. magnification, etc. Therefore, the existing water treatment agent formulations are varied, causing a lot of inconvenience in the process of use
