Abstract
The invention provides an anti-scaling disperser, which comprises acroleic acid-acrylate-petroleum sulfonate copolymer, acrylic acid-2-hydroxypropyl acrylate-AMPS copolymer, maleic anhydride-acrylic acid copolymer, zinc chloride and water, the invention also provides the use of the anti-scaling disperser in industrial water treatment systems. The formulation of the invention can be charged by zinc salts for the treatment of low-medium hardness water, and to increase the inhibition rate of the formulation.
Description
Technical field:
The present invention relates to a kind of chemical reagent that is used for wastewater treatment, relate in particular to the daily maintenance medicament that central air-conditioning recirculated cooling water, industrial circulating cooling water system use in the day-to-day operation process, is a kind of dirt dispersion agent specifically.
Background technology:
In the day-to-day operation process of central air-conditioning recirculated cooling water, industrial circulating cooling water system, be easy to generate inorganic salt crust, the generation of inorganic salt crust can reduce the heat-transfer effect of water system.Early be used for reducing the natural compounds of the inorganic salt crust of water treatment system, as starch, xylogen etc.Along with water coolant develops into the open type recycle system by straight-flow system, begin to adopt add acid, stack gas is stablized technology such as lime carbonate, with Langelier, Ryznar etc. propose to judge the various saturation index of water quality type for representative, and having developed the notion of water conditioning on this basis, Scale inhibitors such as polymeric phosphate with sequestering action are used for various water treatment procedures in a large number.After the sixties in 20th century, because the requirement that the water coolant concentration rate is improved, synthetic compound progressively becomes the main product of Scale inhibitors, and water conditioner fills a prescription also that dirt dispersion agent develops into molybdenum system, tungsten system and full organic system etc. from chromium system, phosphorus system.The appearance of the anti-incrustation corrosion inhibitor of organic phosphine acids, problems such as the corrosion of industrial water system emerged in operation and calcium carbonate scaling have been solved, but under harsh condition of water quality, for many problems such as other dirts that operation under the zinc dirt that occurs in the calcium phosphate scale in the phosphorus line formulation, the alkaline water processing scheme, the high concentration ratio condition may form, it is insurmountable only utilizing organic phosphonate.
Summary of the invention:
Technical problem to be solved by this invention is: because the anti-incrustation corrosion inhibitor of organic phosphine acids calcium phosphate scale and zinc dirt and other dirts occur in industrial water system meeting in service, the present invention is for solving the problems of the technologies described above, the technical scheme that is adopted provides a kind of dirt dispersion agent, described dispersion agent is made up of vinylformic acid-acrylate-co-polymer of sulfonate, vinylformic acid-Propylene glycol monoacrylate-AMPS multipolymer, copolymer of maleic anhydride and acrylic acid, zinc chloride and water, wherein, the weight percent of each component is as follows:
Vinylformic acid-acrylate-co-polymer of sulfonate: 20%～30%
Vinylformic acid-Propylene glycol monoacrylate-AMPS multipolymer: 30%～40%
Copolymer of maleic anhydride and acrylic acid: 10%～15%
Zinc chloride: 3%～4%
Water: 25%～35%
The present invention also aims to provide described dirt dispersion agent in the application in industrial water conditioning system.
The present invention also aims to provide the using method of described dirt dispersion agent, when the present invention uses, can with the composite use of zinc salt, also can use to 8%-12% with zinc chloride is composite, the present invention can also with the composite use of organic phosphonate anti-incrustation corrosion inhibitor, the water coolant that can be used for Steel Plant's drip washing prevents ferric oxide and silt lodging, and is used for high basicity recirculated cooling water.
Physical index of the present invention is as follows:
(a) outward appearance: colourless to light yellow transparent liquid
(b) density: (20 ℃), g/cm3:1.05
(c) solids content: 〉=30.0%
(d) limit viscosity number (30oC), dL/g:0.055--0.095
(e) PH (1% aqueous solution) :≤2.5
(f) free monomer (CH2=CH--COOH meter) content :≤0.5%
The present invention and prior art are compared, and (1) ratio is some sulfonic acid copolymers resistance calcium phosphate scale height in the market; Can be composite to about 10% with zinc chloride, at high PH, make zinc salt not produce precipitation in the high basicity aqueous solution; (2) the present invention can replace the sulfonic acid copolymer used always, can add zinc salt in based on the present invention's prescription, is used for the water quality of soft, can improve the corrosion inhibition rate of prescription.
The present invention is faint yellow or colourless transparent liquid, can dissolve each other with water, has the premium properties that disperses iron, zinc oxyhydroxide and calcium phosphate in alkaline aqueous solution, because of having sulfonic acid group, so lime carbonate is had scale inhibition dissemination preferably.
Embodiment:
A kind of dirt dispersion agent of the present invention, described dispersion agent is made up of vinylformic acid-acrylate-co-polymer of sulfonate, vinylformic acid-Propylene glycol monoacrylate-AMPS multipolymer, copolymer of maleic anhydride and acrylic acid, zinc chloride and water, wherein, the weight percent of each component is as follows:
Vinylformic acid-acrylate-co-polymer of sulfonate: 20%～30%
Vinylformic acid-Propylene glycol monoacrylate-AMPS multipolymer: 30%～40%
Copolymer of maleic anhydride and acrylic acid: 10%～15%
Zinc chloride: 3%～4%
Water: 25%～35%
The present invention also aims to provide the using method of described dirt dispersion agent, when the present invention uses, can with the composite use of zinc salt, also can use to 8%-12% with zinc chloride is composite, the present invention can also with the composite use of organic phosphonate anti-incrustation corrosion inhibitor, the water coolant that can be used for Steel Plant's drip washing prevents ferric oxide and silt lodging, and is used for high basicity recirculated cooling water.During the dispersion agent of dirt dispersion agent of the present invention ferric oxide during as pre-film, dosage (80-100) mg/L.Positive usual amounts is (10-30) mg/L, and being suitable for the PH condition is 7.0-9.5.
