Description
Technical field
The application belong to cyclization reagent technology field more particularly to a kind of environmental protection, the good sterilizing scale inhibiting agent of corrosion inhibition and its
Preparation method.
Background technology
Antisludging agent（scale inhibitor）：Be with can be in disperse water slightly solubility inorganic salts, inhibit or interfere with indissoluble
Precipitation, fouling function of the property inorganic salts in metal surface, and metal equipment is maintained to have a kind of medicament of good heat-transfer effect.
Antisludging agent can remove de-sludging and prevent the formation of incrustation scale, improve heat exchanger effectiveness, reduce electric energy or reduce disappearing for fuel
Consumption;Water process can also reduce blowdown, improve the utilization rate of water, can generally save 60% or more, meet the new policies of China's energy-saving and emission-reduction
Plan.
Research of non-phosphorus scale inhibitor is applicable to different water sources, the product using without phosphorus polymer and dispersed high molecular polymer come
Prevent hardness and oxidation deposition of iron.It is a kind of dynamical liquid dirt dispersion agent, effectively controls calcium carbonate, calcium sulfate, sulfuric acid
Strontium fouling, the LSI of calcium carbonate is up to+3.0 still will not fouling.It can be used for controlling film separation system fouling precipitation and reduce particle and block up
Plug.
Reverse osmosis antisludging agent is used exclusively for reverse osmosis（RO）System and nanofiltration（NF）And ultrafiltration（UF）The antisludging agent of system,
Film surface fouling can be prevented, water yield and production water quality can be improved, reduce operating cost.
RO antisludging agents are one kind of antisludging agent, main component：Organic dispersion, organic complex, antozone hydroxyl are poly-
Close object etc.；The scope of application：The processing of system suitable for pure water system RO process sections.Physical property appearance light color liquid, pH 1.0-
2.5。
Corrosion inhibiter by concentration appropriate and in the form of be present in environment（Medium）When middle, material corrosion can be prevented or slowed down
Chemical substance or compound, therefore corrosion inhibiter is referred to as corrosion inhibitor.Its dosage very little (0.1%~1%), but effect
Significantly.The method of this protection metal claims corrosion inhibiter to protect.Corrosion inhibiter is used for neutral medium（Boiler feed water, recirculated cooling water）、
Acid medium（The hydrochloric acid to descale, the acid dip solution of plating piece derusting before being electroplated）And gas medium（Vapour phase inhibitor）.
Adsorbed film type corrosion inhibiter is mostly organic inhibitor, they have polarity gene, can by metallic surface charge adsorption,
One layer of monomolecular film is formed in entire anode and cathode region, to prevent or slow down the reaction of corresponding electrochemistry.Contain Ru certain
Nitrogen, sulfur-bearing or hydroxyl, organic compound with surface-active, there are two types of incompatible groups in molecule；It is hydrophilic
Base and lipophilic group.The molecule of these compounds is with hydrophilic group（For example, amino）Be adsorbed on metal surface, formed one layer it is fine and close
Hydrophobic film protects metal surface not by aqueous corrosion.Tallow amine, cetylamine and octadecylamine etc. are referred to as the amine of " film amine ",
It is exactly adsorbed film type corrosion inhibiter common in water process.Mercaptobenzothiazoler, benzotriazole and methylbenzotrazole etc. are coloured
Metal（Especially copper）Ideal corrosion inhibiter.Although they and copper metal itself act on film forming, with above-mentioned typical oxidation film
Type corrosion inhibiter is different, is not formed a film with chemisorption by oxidation by forming complex compound with the copper ion of metal surface
's.When metal surface is cleaning or activated state, such corrosion inhibiter can form the satisfactory adsorbed film of corrosion mitigating effect.But such as
In the case that there is corrosion product in fruit metal surface or has dirt deposition, it is difficult to form the corrosion inhibition film to work well, it at this time can be appropriate
A small amount of surfactant is added, to help such corrosion inhibiter to form a film.
Anti-incrustation corrosion inhibitor is made of organic phosphine, excellent copolymer and copper inhibitor etc., is all had to carbon steel, copper and copper alloy
There is excellent corrosion inhibition, there is remarkable scale inhibition and dispersion performance to calcium carbonate, calcium phosphate.This product is mainly used for open type circulating cooling
Water treatment system is particularly suitable for the system of cupric equipment.This product can be used for the water quality of high pH, high alkalinity, high rigidity, be current
One of the water treatment agent of comparatively ideal uncomfortable pH alkaline operations.
Polyamino polyether base methylenephosphonic acid PAPEMPPAPEMP is latest generation water treatment agent, has very high chelating point
It dissipates performance and very high calcium tolerance and excellent scale-inhibiting properties, the medicament can be used as the scale inhibitor of recirculating cooling water system
Agent, especially suitable for high rigidity, high alkalinity, the recirculating cooling water system of high pH and oil field water process.To calcium carbonate, calcium phosphate,
The scale-inhibiting properties of calcium sulfate are excellent, while can effectively inhibit the formation of silicon dirt, and with good stable metal ion such as zinc,
The effect of manganese, iron.PAPEMP is used for the film antisludging agent of counter-infiltration system, the high salinitys such as multi-stage flash system, high concentrtion, height
The scale inhibition of warm system and inhibition（Such as the scale inhibition of the high muddy water system of coal carburetion system high temperature）, textile auxiliary and paper making additive
（Yellowing inhibition agent）, alternative EDTA, DTPA, NTA etc..
From the mechanism of action, the solubilization of effect chelating, cohesion and the peptizaiton of antisludging agent, electrostatic repulsion work
Four parts are acted on, crystal lattice distortion.And in laboratory evaluation experiment, peptizaiton is the remedial measure of chelating effect, lattice
Distortion effect is the remedial measure of peptizaiton.
