Abstract
The invention provides an anti-scaling disperser for water treatment systems, which comprises methyl methacrylate, diacyl hydroperoxide, acrylic acid-2-hydroxypropyl acrylate-AMPS copolymer, maleic anhydride-acrylic acid copolymer, zinc chloride and water, the disperser is fire resistant, it is a stramineus or colorless transparent liquid soluble with water, it possesses the capability of dispersing hydroxide of Fe and Zn, and calcium phosphate in alkaline water solutions, and because the disperser has sulfonic groups, so it has good anti-scaling and dispersing action to calcium carbonate.
Description
Technical field:
The present invention relates to a kind of dirt dispersion agent that is used for water treatment system, relate in particular to the dirt dispersion agent that central air-conditioning recirculated cooling water, industrial circulating cooling water system use in the day-to-day operation process.
Background technology:
In central air-conditioning recirculated cooling water, industrial circulating cooling water system, since water temperature and pressure scope often change, metal ions such as the chlorion in the water, calcium ion, iron ion concentrate along with the continuous reuse of water, be easy to generate inorganic salt crust, the generation of inorganic salt crust can reduce the heat-transfer effect of water system.Once adopted isolation technique to remove inorganic salt crust abroad, but because complicated operation, used widely, existing water conditioner prescription develops into molybdenum system, tungsten system and full organic system etc. from chromium system, phosphorus system, but these water treatment prescriptions have solved inorganic salt crust, but brought other organic contamination, environment has been formed secondary pollution.
Summary of the invention:
Technical problem to be solved by this invention is: owing to adopt isolation technique to remove inorganic salt crust, but because complicated operation, used widely, existing water conditioner prescription develops into molybdenum system, tungsten system and full organic system etc. from chromium system, phosphorus system, but these water treatment prescriptions have solved inorganic salt crust, but brought other organic contamination, environment has been formed secondary pollution.The present invention is for solving the problems of the technologies described above; the technical scheme that is adopted provides the dirt dispersion agent in a kind of water treatment system; described dispersion agent is made up of hydroxy methyl methacrylate, diacyl peroxide, 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:
Hydroxy methyl methacrylate, 10%～15%,
Diacyl peroxide: 10%～15%,
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 application of the dirt dispersion agent in the described water treatment system in industrial water conditioning system.
The present invention also aims to provide the using method of the dirt dispersion agent in the described water treatment system, 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.
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 8%-12% 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 high temperature resistant, be faint yellow or colourless transparent liquid, can dissolve each other with water, have the premium properties that in alkaline aqueous solution, disperses iron, zinc oxyhydroxide and calcium phosphate, because of having sulfonic acid group, so carbonic acid is had scale inhibition dissemination preferably.
Embodiment:
Dirt dispersion agent in a kind of water treatment system of the present invention; described dispersion agent is made up of hydroxy methyl methacrylate, diacyl peroxide, 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:
Hydroxy methyl methacrylate, 10%～15%,
Diacyl peroxide: 10%～15%,
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%.
During the dispersion agent of the ferric oxide during of the dirt dispersion agent in the water treatment system of the present invention 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.
