Description
Technical field
The application belongs to environmental protection reagent process field, particularly relates to a kind of environmental protection, low-phosphorous environment-friendly scale inhibitor that corrosion inhibition is good and preparation method thereof.
Background technology
Scale inhibitors (scaleinhibitor): be the insoluble inorganic salt had in energy disperse water, prevention or the precipitation of interference insoluble inorganic salt in metallic surface, fouling function, and maintain the class medicament that hardware has good heat-transfer effect.Cold exchange device antiseptic corrosion inhibitor is with epoxy resin and specific amino resin for base-material, and it is formulated to add the appropriate various auxiliary agent such as various antirust, anticorrosion, is single component.It has excellent shielding, impervious, rustless property, good scale inhibition, thermal conductivity, the performances such as excellent weak acid resistant, highly basic, solvent, its strong adhesion, and rete is bright, pliable and tough, fine and close, hard.Corrosion inhibiting and descaling agent is made up of organic phospho acid, poly carboxylic acid, carbon steel corrosion inhibitor etc., calcium carbonate in water, calcium phosphate etc. are all had to good chelating dissemination and have good corrosion mitigating effect to carbon steel, be mainly used in the corrosion-mitigation scale-inhibition of Steel Plant's recirculating cooling water system, its corrosion mitigating effect is good, scale inhibition power is strong.
The result of dissemination stops into dirt interparticlely contact with each other and condense, thus can stop the growth of dirt.Becoming dirty particle can be calcium, magnesium ion, can also be dust, silt or other water-insolubles.Metal passivator is the polymkeric substance with certain relative molecular mass (or polymerization degree), and the height of dispersing property is closely related with the size of relative molecular mass (or polymerization degree).The polymerization degree is too low, then few by absorption divided particles number, dispersion efficiency is low; The polymerization degree is too high, then too much by absorption divided particles number, water body becomes muddy, even forms flco (effect is now close with flocculation agent).Compared with sequestering action, dissemination is efficient.In middle high hardness water, the divergent function of Scale inhibitors plays a major role.The combination product that boiler special corrosion and scale inhibitor is made up of the superpolymer such as organic phospho acid and poly carboxylic acid, has very high inhibition and scale-inhibiting properties, and its temperature tolerance is good especially, water treatment in the stove that can be effectively applied to low pressure boiler.
Owing to containing the sulfonic group of the good carboxylic acid group of scale inhibition and dispersion performance and strong polarity in molecular structure, can calcium tolerance be improved, have significant scale effect to the calcium phosphate in water, calcium carbonate, zinc dirt etc., and dispersing property be excellent.Composite with organic phosphine, synergism is obvious.Being particularly suitable for the water quality of high pH, high alkalinity, high rigidity, is one of optimal scale inhibition metal passivator realizing high concentration multiple operation.
Heat supply network scale inhibitor special is primarily of compositions such as efficient metal passivator, phenolic hydroxyl group, sulfonic acid groups, the dirty factor is become to have lattice distortion effect to the calcium carbonate in water, calcium sulfate etc., dirt is not easily adsorbed on wall securely, and loosely is dispersed in water, and demonstrates excellent scale effect.
EDTMPS is nitrogenous Sunmorl N 60S, and belong to cathode type inhibiter, compared with inorganic polyphosphate, corrosion inhibition rate is high 3 ~ 5 times.Can be miscible with water, nontoxic pollution-free, chemical stability and temperature tolerance good, at 100 DEG C, still have good scale inhibition effect.EDTMPS can be dissociated into 8 negative ions in aqueous, thus can with multiple metal ion-chelant, form the netted complex compound of multiple monomer structure macromole, loosely is scattered in water, make calcium dirt normal crystallization be destroyed.EDTMPS is good to the scale inhibition effect of calcium sulfate, barium sulfate scale.The combination product that boiler special corrosion and scale inhibitor is made up of the superpolymer such as organic phospho acid and poly carboxylic acid, has very high inhibition and scale-inhibiting properties, and its temperature tolerance is good especially, water treatment in the stove that can be effectively applied to low pressure boiler.Corrosion inhibiting and descaling agent forms by organic phospho acid, poly carboxylic acid, carbon steel corrosion inhibitor and copper inhibitor are composite, and the calcium carbonate in water, calcium sulfate, calcium phosphate etc. are all had to good chelating dissemination and have good corrosion mitigating effect to carbon steel, copper.
EDTMPA has the ability of very strong chelated metal ions, is maximum in all sequestrants comprising EDTA with the complexation constant of cupric ion.EDTMPA is high purity reagent and nontoxic, can be used as the clean-out system of semi-conductor chip for the manufacture of unicircuit in electron trade; That makes radioelement in pharmaceutical industries carries agent, for checking and disease therapy; The sequestering power of EDTMPA, almost all can be alternative with EDTMPA in all places using EDTA to make sequestrant far more than EDTA and DTPA.Heat supply network scale inhibitor special is primarily of compositions such as efficient metal passivator, phenolic hydroxyl group, sulfonic acid groups, the dirty factor is become to have lattice distortion effect to the calcium carbonate in water, calcium sulfate etc., dirt is not easily adsorbed on wall securely, and loosely is dispersed in water, and demonstrates excellent scale effect.And universal along with humanity concept, and the formation of novel harmonious society, designs that a kind of scale inhibition effect is good, stability is strong, low-phosphorous and low-phosphorous environment-friendly scale inhibitor that corrosion mitigating effect is good and preparation method thereof is very important.
