Description
Technical field
The present invention relates to water treatment agent field, specifically a kind of high temperature resistant corrosion inhibiting and descaling agent.
Background technology
The deficient and pollution of water resources in china has caused the serious concern of people, industrial with industrial growing
Water is increased rapidly, and wherein industrial circulating cooling water accounts for more than the 60% of industrial water., the cooling water during cooling water circulation
Constantly evaporation, the salt in water is concentrated deposition, and these biologies are rapidly bred under the control environment of recirculating cooling water system
And growth, produce substantial amounts of biological clay, dirt attachment or be deposited on the surface of water-system pipeline and equipment, severely impact
Circulating water condensing, cooling effect, increased SR and end is poor, improve energy consumption, and even pipeline is blocked when serious, corrode
Equipment reduces service life of equipment, increased repair rate, threatens normal production run, therefore, must in recirculated cooling water
The medicaments such as killing algicide, antisludging agent and corrosion inhibiter need be added to prevent fouling, corrosion and bacterium, the algae and aquatic of circulation
The rapid breeding and growth of thing.
In the exploitation in oil field, it is ensured that the stabilization in oil field, volume increase, fouling is rationally and effectively removed, as urgent in oil field development
The problem for needing to solve, the most frequently used method of scale inhibition is the generation for suppressing incrustation scale using chemical scale-inhibitor both at home and abroad.Conventional change
Antisludging agent is mainly including inorganic polyphosphate, organic multicomponent phosphate, homopolymers antisludging agent, copolymer antisludging agent etc..But,
The features such as having high temperature, high rigidity, salinity high due to oil field water quality, these existing chemical scale-inhibitors are solving oil field system
During scale problems, often due to stability is not enough, and fouling can not be effectively removed, final influence oil-water well normal work.
In boiler for producing, general boiler feed water makes water be contacted with exchanger using ion exchange softener, reduces the hardness of water
I.e. calcium ions and magnesium ions content, softens water, and resin is regenerated, and recycles.But it has problems in that, resin warp
After crossing long-term repeated regeneration use, its exchange capacity also declines therewith.Therefore, into the boiler water in stove hardness also gradually
Increase, and at high temperature repeatedly circulation after substantial amounts of pure water evaporated, greatly increase the calcium in water, magnesium ion concentration,
Fouling type material such as Ca2+、Mg2+Precipitation is produced Deng because solubility declines, the material of precipitation can be deposited on the heat transfer sheet of seamless steel tube for boiler
On face, incrustation scale is formed.
