Description
Technical field
The present invention relates to a kind of corrosion inhibiter, belong to water treatment field, in particular to a kind of multiple elements design corrosion inhibiter and
Preparation method.
Background technology
Current water resources shortage has become one of China or even whole world coming crisis in Western sociology, using water wisely and the profit of raising water resource
It has been imperative by rate, very urgent.Thus water saving first has to from the beginning of the industrial or agricultural comparing concentration with water.Due to
In water for industrial use, cooling water accounts for again 60%--70%, and undoubtedly, saving cooling water becomes the key subjects of Industrial Water Saving.Cold
But water can be divided into once-through cooling water and recirculated cooling water two kinds.The former is that the water after cooling is directly discharged, thus consumption
The water yield is big；Recirculated cooling water is used further to cooling by cooling tower after then the water after being water-cooled being lowered the temperature.Cooling water circulation makes
With rear, due to the continuous evaporation of moisture, add with air be fully contacted so that the salt in water is concentrated, bacterium and molten
Solution oxygen content is greatly increased, cause recirculated cooling water occur serious fouling, corrosion and bacterium algae grow three big disadvantages, make be
The heat exchange efficiency of system is greatly lowered, and frequently, what even serious threat produced is normally carried out in maintenance.For that purpose it is necessary in cooling
Water adds antisludging agent, corrosion inhibiter, Biocidal algae-killing agent and other cleaning agent being correlated with supporting, prefilming agent, flocculant etc..
The technological package that this addition chemical agent grows to prevent recirculated water fouling, burn into bacterium algae is referred to as at chemical water
Reason technology.Water Treatment technology is the effective means that the Industrial Water Saving generally acknowledged outside Present Domestic commonly uses most.
For a long time, people have carried out substantial amounts of research to antiscale or scale inhibition, anticorrosion or the inhibition of water, it is proposed that various respectively
The water treatment agent of sample.Representational is chromate anti-incrustation corrosion inhibitor, phosphorus system anti-incrustation corrosion inhibitor and molybdenum system anti-incrustation corrosion inhibitor
Deng.They are relatively big because of toxicity, or have been abandoned because easily generating the shortcomings such as calcium phosphate scale or just abandoned.Due to environmental legislation
Increasingly stringent, for protect the mankind living environment, people are just continually looking for new effective anti-incrustation corrosion inhibitor.Copolymer
Dispersing and antisludging corrosion inhibitor is the class New Type Water Treatment Chemicals developed since the eighties.Containing carboxylic acid group, sulfonic group and amide groups
Acrylic trepolymer, due in molecular structure sulfonic acid base exist, make it to play and comprise only carboxylic acid group
With suppression calcium phosphate scale during amide groups, calcium carbonate scale, dispersing iron oxide, dispersion dust and the advantage of dispersion mud etc.,
Also adapt to the cooling water ring border of very high rigidity, moreover it is possible to improve the scale inhibition performance to calcium phosphate further simultaneously.Since 1998,
Domestic East China University of Science has carried out abundant research to aspects such as the synthesis of poly-aspartate (PASP), scale-inhibiting properties.Experiment
Find in the case of low dosage, molecular weight be 4000 poly-aspartate there is the most excellent scale-inhibiting properties.Poly-sky
Winter propylhomoserin can be applicable to the water system that high-calcium ionic, high temperature and pH value are higher.Individually poly-aspartate has excellent resistance
Dirt performance, but corrosion inhibition is poor.Polyepoxy sodium succinate (PESA) is also that the one progressively grown up last year is green
Colour chemistry water treatment agent.It has higher scale-inhibiting properties, without phosphorus nitrogen-free, the advantage such as biodegradable.Poly-epoxy succinic
The scale-inhibiting properties of acid sodium is substantially better than Sodium Polyacrylate (PAAS), poly sodium (HPMA) and tartaric acid
(tartaric acid).Individually polyepoxy sodium succinate also has certain corrosion inhibition, but its corrosion inhibition is organic with other
Phosphonate corrosion inhibiter is compared poor.
