Description
Technical field
The invention belongs to field of fine chemical, more particularly to a kind of terpolymer antisludging agent and preparation method thereof.
Background technology
Water is to maintain all life base substance for breeding, grow, developing on the earth, be also human society Emergence and Development,
Flourishing fundamental driving force.China has a vast territory, populous, and compared to other countries, water resource occupation rate is relatively per capita
Low, as the representative of developing country, economic development is swift and violent in recent years, and the water resources consumption amount generated therewith is also growing day by day,
More stubborn problem is the worsening of water environment.The pollution problem of the scarcity and water environment of water resource is as great influence
One of factor has seriously restrained China or even world economy stabilization and sustainable development.As important power of promoting economic development
The industrial enterprise of amount, water consumption proportion account for larger proportion in total water consumption, and in China, this proportion is about 1/5th,
And wherein recirculated cooling water occupies 60%~90%.Therefore, the use of industrial circulating cooling water how is controlled to greatest extent
And how to contain that a series of its a large amount of water environmental problems using initiation is major world problem urgently to be resolved hurrily at present.
In order to prevent and control water resource pollution, the cyclic utilization rate of water resource is improved, so as to reach environmental protection and section
The purpose of water is about used, water treatment agent (also referred to as Water Treatment Chemicals) is extensive in sector applications such as oil, chemical industry, smelting, medicine.
It in industrial circulating cooling water, needs to add appropriate water treatment agent, so as to which equipment burn into pipeline scale or microorganism be inhibited to stick
The caused production accident of the problems such as mud or security threat improve its cycling and reutilization rate, reach low emission or zero-emission, together
When control the pollution that its stain disease generates environment.Although throwing highest attention in face of severe pollution problem world community,
Management increasingly increases with intensity, but the Traditional Thinking root depth that many countries, especially developing country first develop, administer afterwards
The base of a fruit is consolidated.The root of pollution problem is solved from source to be particularly important, also of interest by more and more people.People at present
Constantly develop new water treatment agent, but P containing sludge inhibitor still accounts for the most of of antisludging agent.Phosphorus content is excessively high
It can promote the production of algae in cooling water, be formed " soft dirt ", the eutrophication of water body and " red tide " phenomenon are caused after discharge：Very much
It though water soluble polycarboxylic acid class water treatment agent is non-toxic, can not degrade, chemical oxygen consumption (COC) in water be caused to increase, also to water body
It pollutes.
