Description
Technical field
The present invention relates to circulating water cooling treatment field, and in particular to a kind of without phosphorus slow-release scale inhibitor.
Background technology
Circulating water cooling treatment is most commonly used technology using slow-release scale inhibitor, can save using and subtracting for fresh water
Few blowdown, is typical energy-saving and emission-reduction measure while improving usage cycles and the life-span of production equipment.Existing slow-release scale inhibitor is big
It is main raw material(s) to use organophosphor or Phos more, and phosphorus can cause body eutrophication, cause algal bloom, frond
Being decomposed after death can make water body produce musty and stink, have a strong impact on the existence of the aquatiles such as fish.Country is not met at all
The circulating water cooling treatment of promotion improves recycling rate, reduce fresh water use and blowdown, slow-release scale inhibitor low-phosphorousization or
Requirement without phosphatization.
The content of the invention
The technical problems to be solved by the invention are：For the richness in not enough and domestic each waters of above-mentioned prior art products
A kind of problem that nutrient laden is caused, there is provided without phosphorus slow-release scale inhibitor, this product meet national energy-saving emission reduction, environmental protection will
Ask.
In order to solve the above technical problems, the technical solution adopted in the present invention is：A kind of without phosphorus slow-release scale inhibitor, it presses weight
Amount percentage is made up of following components：Acrylic acid/2- acrylamide -2- methyl propane sulfonic acids 20-30%, poly-aspartate 15-
25%th, sodium gluconate 5-8%, zinc chloride 6-10%, azole 0.8-1%, sulfuric acid 2-5%, balance of deionized water, each component sum
It is 100%.
Preferably, above-mentioned slow-release scale inhibitor is made up of following components by weight percentage：Acrylic acid/2- acrylamides -2-
Methyl propane sulfonic acid 24-30%, poly-aspartate 20-25%, sodium gluconate 6-8%, zinc chloride 8-10%, azole 0.8-1%, sulphur
Sour 2-5%, balance of deionized water, each component sum is 100%.
The above-mentioned azole for referring to is TTA（TTA）, mercapto benzothiazole（MBT·Na）Or benzotriazole
（BTA）.
Acrylic acid/2- acrylamide -2- methyl propane sulfonic acids (AA/AMPS) compares existing market in Main Ingredients and Appearance of the invention
On some sulfonic acid copolymers resistance phosphoric acid dirt it is high, and can be compounded to 10% or so, in PH high, aqueous alkali high with zinc chloride
Middle zinc salt does not produce precipitation.Disperse the function admirable of iron, zinc, hydroxide and calcium phosphate in alkaline aqueous solution, because with sulphur
Acid gene, therefore the solubility of carbonate can be increased in high calcium solution.
There is amido link and carboxyl key simultaneously in the molecular structure of poly-aspartate, centrality type and anionic are in one
Body, poly-aspartate is used as water quality stabilizer, there is certain sustained release performance, while scale-inhibiting properties are very well, and with very good
Biocompatibility and degradability, it is nontoxic.Poly-aspartate has the feature of polyanion surfactant and has
The biodegradability of similar glucose, has good resistance to the scaling salt class such as calcium carbonate, calcium sulfate, barium sulfate, calcium phosphate
Dirty effect, to the scale inhibition performance of calcium carbonate up to 100%.There is peptizaiton and the corrosion of hardware can be effectively prevented simultaneously,
Using it is rear it is degradable be environmentally acceptable final product.Anion can be dissociated into aqueous, along with amido link
The lone pair electrons of institute's band on N, O, therefore can be by physical absorption and chemisorbed the Cd in the aqueous solution2+Adsorpting aggregation rises
Come, so as to reach the purpose of removal.
Sodium gluconate is used as water quality stabilizer, and its superiority shows：(1) there is obvious coordinating effect, it is adaptable to
The various formulas such as molybdenum, silicon, phosphorus, tungsten, nitrite, due to coordinating effect influence, corrosion mitigating effect is greatly improved；(2) with general inhibition
Agent is conversely, corrosion inhibition rate is raised and increased with temperature；(3) scale prevention ability technical requirements have very strong complexing energy to calcium, magnesium, molysite
Power, especially to Fe3+There is fabulous chelation；(4) as recirculated cooling water corrosion inhibiting and descaling agent, be used at present other delay
Erosion antisludging agent is incomparable, can reach the effect of public hazards of going out.
The preparation of without phosphorus slow-release scale inhibitor of the invention：According to said ratio remove ionized water add reactor in, stirring
（Rotating speed is 55-65 revs/min）, first add zinc chloride, sodium gluconate is added after dissolving, then sequentially add acrylic acid/
2- acrylamide -2- methyl propane sulfonic acids, poly-aspartate, are well mixed, and add azole, and sulfuric acid regulation is added after dissolving
PH, is filtered after mixing using cloth envelop collector, you can.Because there is sulfuric acid in this production, it is noted that safety in use, it is impossible to
Add excessive velocities（Rotating speed is controlled at 55-65 revs/min）, can not be by water toward adding in sulfuric acid.
When the concentration of phosphate-free corrosion inhibition antisludging agent of the invention is 30mg/l, to total hardness in 100 mg/l, total alkalinity
There is good corrosion mitigating effect in the water of such as ChangJiang River of 100 mg/l, corrosion of carbon steel speed is less than 0.075mm/a；Use
When concentration is 40mg/l, to total hardness in 300 mg/l, total alkalinity in the water system of 200 mg/l, chlorion more than 300 mg/l
Water has good corrosion mitigating effect, and corrosion of carbon steel speed is less than 0.075mm/a；During concentration 60mg/l, to total hardness 50
Mg/l, total alkalinity are good in the corrosion mitigating effect of the super-low-hardness condition of water quality such as such as Min River water system of 50 mg/l.
Concertedness is good between each component of the present invention, and accommodation extensively, possesses good promotional value.The present invention is more traditional
Formula contrast has the following advantages that：1. it is extensive that water system is applicable；2. more preferable inhibition and scale inhibition effect is had under identical consumption；
3. environmental protection and public nuisance free, the phosphorous body eutrophication for causing is not had and causes second pollution.
