Abstract
The invention provides a molybdate anti-scaling disperser, which comprises molybdates, orthophosphates, PBTCA, water soluble polymers, methylbenzotriazole, diacid and water. The objectives of the invention is to provide the use of the anti-scaling disperser in industrial water treatment systems, and to provide the method of use of the anti-scaling disperser, which can be used along with zinc salts in composite, or compounded with zinc chloride to 8-12%.
Description
Technical field:
The present invention relates to a kind of daily maintenance medicament that central air-conditioning recirculated cooling water, industrial circulating cooling water system use that is used for, is a kind of dirt dispersion agent specifically, especially a kind of molybdenate dirt dispersion agent.
Background technology:
Because requirement on environmental protection; develop green water conditioner and become one of focus of Treatment of Industrial Water research; 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., but these natural compoundss degraded by Institute of Micro-biology easily, do not reach good effect.
Summary of the invention:
Technical problem to be solved by this invention is: because because requirement on environmental protection; develop green water conditioner and become one of focus of Treatment of Industrial Water research; 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., but these natural compoundss are degraded by Institute of Micro-biology easily, do not reach good effect, the present invention is for solving the problems of the technologies described above, and the technical scheme that is adopted provides a kind of molybdenate dirt dispersion agent, and described dispersion agent is made up of molybdate, orthophosphoric acid salt, PBTCA, water-soluble polymers, methyl benzotriazazole and diprotic acid and water, wherein, the weight percent of each component is as follows:
Molybdate: 20%～30%,
Orthophosphoric acid salt: 28%～35%,
PBTCA：10％～15％，
Methyl benzotriazazole: 3%～4%,
Diprotic acid: 2%～5%,
Water: 25%～35%.
The present invention also aims to provide described molybdenate dirt dispersion agent in the application in industrial water conditioning system.
The present invention also aims to provide the using method of described molybdenate 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 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.
Experiment shows that the present invention has good corrosion mitigating effect, these compound molybdenums are prescription, synergistic function by molybdate and other medicaments, reaching under the condition of same corrosion mitigating effect, what make molybdate adds concentration from reducing to several mg/L more than the 200mg/L, for applying of molybdate series inhibiter created favourable condition.
Embodiment:
A kind of molybdenate dirt dispersion agent of the present invention, described dispersion agent is made up of molybdate, orthophosphoric acid salt, PBTCA, water-soluble polymers, methyl benzotriazazole and diprotic acid and water, and wherein, the weight percent of each component is as follows:
Molybdate: 20%～30%,
Orthophosphoric acid salt: 28%～35%,
PBTCA：10％～15％，
Methyl benzotriazazole: 3%～4%,
Diprotic acid: 2%～5%,
Water: 25%～35%.
The present invention also aims to provide the using method of described molybdenate 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.
