Description
The invention belongs to slow molten solid water treating agent.
So far, poly-phosphate delays molten solid water treatment medicament, is generally made through high-temperature fusion by corresponding acidity and basic oxide.For example, English Patent 1005691 is with sodium phosphate, and zinc oxide, siliceous calcium phosphate are 1000～1200 ℃ of fusions, and slowly cooling makes then.For another example, English Patent 1298605 is to make being higher than 1200 ℃ of following fusions containing sodium oxide, calcium oxide, magnesian poly-phosphate.The solid water treatment medicament that technology like this makes is vitreum, has slow dissolubility energy in water, and plays the effect that suppresses metallic corrosion, but its scale inhibition effect is not satisfactory.
The present invention aims to provide a kind of solid water treatment medicament, and this medicament not only has slow molten, corrosion inhibition and effect, and has good scale effect simultaneously.
This medicament carries out neutralization reaction with the acidity and the basic oxide of phosphorus, silicon, sodium, calcium, magnesium, carries out high temperature polymerization again, makes vitreum.During use, be immersed in the flowing water, slowly effective ingredient is separated out in dissolving, prevents corrosion of metal and fouling.
This medicament uses phosphoric acid, yellow soda ash or sodium hydroxide, lime carbonate or calcium oxide, alkaline magnesium carbonate or magnesiumcarbonate, silicon-dioxide, zinc oxide to be raw material, control soda acid ratio is 1.5: the 1.0(weight ratio), above-mentioned raw materials at first mixes in reactor and carries out neutralization reaction, for reaction can evenly be carried out, to constantly stir during neutralization reaction.Then,, generate the vitreum of fusion homogeneous, be crushed to suitable granularity after the quick cooling the material after the neutralization reaction when carrying out polyreaction for 800～1000 ℃ 1～2 hour, or direct casting.
Above-mentioned soda acid than its meaning is: acid promptly refers to acidic oxide, as phosphoric acid.Alkali promptly refers to basic oxide, as yellow soda ash, and has comprised silicon-dioxide and zinc oxide.The weight ratio of all acidic oxides and all basic oxide (comprising silicon-dioxide, zinc oxide) is 1.5: 1.0.
This medicament at condition of water quality is: Ce
-500PPm, SO
2- 4500PPm, Ca
2+250PPm(is with CaCO
3Meter), Mg
2+25PPm, use in the water that water temperature is about 50 ℃ PH=8.0～8.5, and medicament content in water is that 6PPm(is with PO
3- 4Meter) during the left and right sides, the corrosion of Carbon Steel rate is can be controlled in 0.02mm/～0.083mm/.In water quality be: Ca
2+270PPm, HCO
- 3270PPm(is with CaCO
3Meter), 70 ℃ of water temperatures are under PH=8.5～9.0 conditions, to CaCO
3Scale inhibition performance be 92～96%.This medicament under high density (600～800PPm), can be used as prefilming agent, its pre-film effect is good.
Following example is an example with synthetic 100Kg medicament all.
Example 1
Phosphatase 11 20Kg, lime carbonate 10Kg, alkaline magnesium carbonate 10Kg and a small amount of silicon-dioxide and yellow soda ash.In reactor, mix to stir, carry out neutralization reaction, move into crucible then, in the high temperature polymerization stove, under 800 ℃～1000 ℃, carried out polyreaction 1～2 hour, cool off rapidly after coming out of the stove and be crushed to 10～30mm.
This medicament is put into one for medicine, put into tank, flowing water is 20 liters/hour by the flow of medicine applying device.During use, medicament in water concentration 6PPm(with PO
2 4PO
3- 4Meter).In water quality is Cl
-500PPm, SO
2- 4500PPm, Ca
2+250PPm(is with CaCO
3Meter), 50 ℃ of water temperatures under PH8.0～8.5 conditions, under the normal operation situation, are controlled at 0.034mm/ to its corrosion rate of carbon steel.In water quality be: Ca
2+270PPm, HCO
- 3270PPm(is with CaCO
3Meter), 270 ℃ of water temperatures, under PH=8.5～9.0 conditions, medicament is concentration 6PPm in water, to CaCO
3Scale inhibition performance be 95.1%.
Example 2
Phosphatase 11 20Kg, lime carbonate 20Kg, caustic soda 10Kg and a small amount of silicon-dioxide and yellow soda ash.Neutralization, polymerizing condition are with example 1, casting.
Under the situation with example 1, its corrosion rate of carbon steel is controlled at 0.02mm/ at condition of water quality and drug concentration, scale inhibition performance is 92.4%.
Example 3
Phosphatase 11 20Kg, lime carbonate 4Kg, zinc oxide 8Kg, caustic soda 10Kg and a small amount of silicon-dioxide and yellow soda ash.Neutralization, polymerization forming condition are with example 1.
Under the situation with example 1, the corrosion of carbon steel rate is controlled at 0.083mm/ at condition of water quality and drug concentration, scale inhibition performance is 95.6%, and medicament concentration in water is under 600～800PPm, can be used as prefilming agent.
