Abstract
Be grouped as the invention discloses a kind of scale inhibitor for industrial circulating cooling water, 1. by the group of following parts by weight: 15-25 parts of polyacrylic acid, 20-30 parts of aminotrimethylene phosphoric acid, 10-20 parts of potassium nitrite, 5-15 parts of sodium hydroxide, 1-10 parts of azole derivative, surplus are industrial water.The present invention has scale inhibition effect obvious compared with prior art, raw material is easy to get, free from environmental pollution, and production cost is low, it is a kind of efficient scale inhibitor for having very much industrial application to be worth, suitable for being engaged in electric power, chemical industry, petroleum, metallurgy, medicine and other fields circulation prevents from that dirt is borrowed to use.
Description
Technical field
The present invention relates to antisludging agents, and in particular to a kind of scale inhibitor for industrial circulating cooling water.
Background technique
Cooling water is widely used in the industry such as electric power, chemical industry, metallurgy, chemical fertilizer and low-pressure boiler, oil-field flooding, oil transportation
Pipeline etc., being used for a long time in recirculated cooling water will appear as crystallites or the mud such as calcium carbonate, calcium sulfate, barium sulfate, calcium chloride, zinc dirt
Sand is dispersed in water non-setting substance etc., will substantially reduce the performance of action of circulating, influences work ratio, serious to incite somebody to action
Equipment, pipeline, components etc. are damaged, therefore, this problem must be handled well.The application of recirculated cooling water
Range is very extensive, and demand is also very large, and therefore, effect is ideal, and lower-cost cold water process product is the following city
The demand of field.The present invention provides a kind of scale inhibitor for circulating cooling water, dedicated for the salt crystalline substance formed in inhibition, dispersion cooling water
Body or crystallite, indissoluble object and the dirt for hindering cooling water effect etc., effect is very ideal, lower production costs, simple process,
It is suitable for promoting and applying.
Summary of the invention
The purpose of the present invention is in view of the deficiencies of the prior art and provide a kind of scale inhibitor for industrial circulating cooling water, it is adopted
It is formulated with pollution-free, non-corrosive or low-corrosiveness industrial chemicals, raw material are easy to get, free from environmental pollution, production cost
It is low, it is a kind of efficient scale inhibitor for thering is very much industrial application to be worth.
In order to solve the above technical problems, the technical solution adopted by the present invention are as follows:
A kind of scale inhibitor for industrial circulating cooling water is grouped as by the group of following parts by weight: 15-25 parts of polyacrylic acid, amino trimethylene
20-30 parts of methyl acid phosphate, 10-20 parts of ethanol amine, 10-20 parts of potassium nitrite, 5-15 parts of sodium hydroxide, azole derivative 1-
10 parts, surplus be industrial water.
Preferably, the azole derivative is one of benzotriazole or methyl phenylpropyl triazole.
Preferably, the scale inhibitor for industrial circulating cooling water is grouped as by the group of following parts by weight: 20 parts of polyacrylic acid,
26 parts of aminotrimethylene phosphoric acid, 14 parts of ethanol amine, 13 parts of potassium nitrite, 12 parts of sodium hydroxide, 4 parts of benzotriazole, surplus
For industrial water.
Preferably, the scale inhibitor for industrial circulating cooling water is grouped as by the group of following parts by weight: 16 parts of polyacrylic acid,
It is 28 parts of aminotrimethylene phosphoric acid, 11 parts of ethanol amine, 18 parts of potassium nitrite, 6 parts of sodium hydroxide, 7 parts of methyl phenylpropyl triazole, remaining
Amount is industrial water.
Preferably, the scale inhibitor for industrial circulating cooling water is grouped as by the group of following parts by weight: 23 parts of polyacrylic acid,
