Abstract
The invention discloses a circulating water antisludging agent which is characterized by comprising the components in percentage by weight: 20-30% of isopropyl maleate, 30-40% of 3-amino isopropyl crotonate, 5-10% of sodium dihydrogen phosphate, 10-20% of zinc nitrate and the balance of water. The invention further provides an application of the circulating water antisludging agent. The antisludging agent disclosed by the invention is simple in formula and easy to produce. The antisludging agent can be used in weakly acidic or neutral circulating water which is not maintained in a high pH value system, so that the antisludging agent is low in cost, and has good social and economic benefits.
Description
Technical field
The present invention relates to Scale inhibitors technical field, refer to particularly it is a kind of circulating water antisludging agent and application thereof.
Background technology
Industrial production recirculated cooling water is constantly recycling in process: recirculated water easily produces dirt in circulating water pipeline.Therefore need to add scale inhibition agent in recirculated cooling water, to slow down in recirculated water fouling process in use.At present, traditional Scale inhibitors production cost is high, and complex process needs to use high recirculated cooling water to remain on high pH value system in use procedure.Increase the scale inhibition cost of recirculated cooling water.
Summary of the invention
Object of the present invention is exactly circulating water antisludging agent and the application thereof that will provide a kind of, solves traditional Scale inhibitors production cost high, and traditional Scale inhibitors need to remain under high pH value system and cause the problem that scale inhibition cost is high.
For achieving the above object, circulating water antisludging agent provided by the present invention, its special character is: according to mass percent meter, it comprises 20～30% toxilic acid isopropyl ester, 30～40% the amino β-crotonic acid isopropyl ester of 3-, 5～10% SODIUM PHOSPHATE, MONOBASIC, 10～20% zinc nitrate, surplus is water.
As preferred version, according to mass percent meter, it comprises 25～30% toxilic acid isopropyl ester, 35～40% the amino β-crotonic acid isopropyl ester of 3-, and 8～10% SODIUM PHOSPHATE, MONOBASIC, 15～20% zinc nitrate, surplus is water.
Further, according to mass percent meter, it comprises 25% toxilic acid isopropyl ester, 35% the amino β-crotonic acid isopropyl ester of 3-, and 8% SODIUM PHOSPHATE, MONOBASIC, 15% zinc nitrate, surplus is water.
The present invention also provides a kind of application of above-mentioned circulating water antisludging agent, and its special character is: add the above-mentioned circulating water antisludging agent of 8～10g at every 1m3 recirculated water.
The invention has the advantages that:
One, this Scale inhibitors formula is simple, produces simple and easy.
Its two, this Scale inhibitors can use in weak acid or neutral recirculated water, recirculated water is without remaining on a high pH value system, scale inhibition cost is low, has good society and economic benefit.
