Examples
example 1
[0019] Example 1: at N 2 Add 100g of polyethylene glycol diallyl ether to the protected reactor, adjust the temperature to 70°C, add 25g of itaconic acid, 0.2g of 8-allyloxy-1,3,6-pyrene trisulfonate sodium , Potassium persulfate (0.5g), mixture of sodium persulfate (0.5g) and potassium metabisulfinate (0.5g), 220g of water, after completion, continue to react at 70°C for 3.5h, after cooling down to room temperature, the fluorescent Identify phosphorus-free environmentally friendly polyether multifunctional water treatment agent (PEGDEYG).
[0020] Gained PEGDEYG water treatment agent is when dosage is 8mg / L, to Ca 3 (PO 4 ) 2 Scale inhibition rate up to 99.5%, for CaCO 3 Scale inhibition rate is 92.7%, for CaSO 4 The scale inhibition rate is 95.6%. , The light transmittance of Fe(III) solution, which characterizes the performance of dispersing iron, is 15.2%, and the corrosion inhibition rate of carbon steel can reach 93.7%.
example 2
[0021] Example 2: at N 2 Add 100g of polyethylene glycol divinyl ether into the protected reactor, adjust the temperature to 70°C, add 188g of acrylic acid, 8.5g of 8-allyloxy-1,3,6-sodium pyrenetrisulfonate, 3g of over Sodium sulfate and 335g of water, after completion, the temperature was raised to 80°C to continue the reaction for 3 hours, and after cooling down to room temperature, a fluorescent label-free phosphorus-free and environmentally friendly polyether multifunctional water treatment agent (PEGDEYG) was prepared.
[0022] When the dosage of the obtained PEGDEYG water treatment agent is 8mgL, the Ca 3 (PO 4 ) 2 Scale inhibition rate up to 99.7%, for CaCO 3 Scale inhibition rate is 91.5%, for CaSO 4 The scale inhibition rate is 93.8%, the light transmittance of the Fe(III) solution which characterizes the performance of dispersing iron is 16.1%, and the corrosion inhibition rate for carbon steel can reach 94.7%.
example 3
[0023] Example 3: at N 2 Add 150g of polyethylene glycol diallyl ether to the protected reactor, adjust the temperature to 80°C, add 120g of hydroxypropyl acrylate, 73g of 8-allyloxy-1,3,6-sodium pyrenetrisulfonate , 16g of sodium persulfate, and 875g of water. After the completion, the reaction was continued at 80°C for 6.8h, and after cooling down to room temperature, a fluorescent label-free phosphorus-free environmentally friendly polyether multifunctional water treatment agent (PEGDEYG) was prepared.
[0024] Gained PEGDEYG water treatment agent is when dosage is 8mg / L, to Ca 3 (PO 4 ) 2 Scale inhibition rate up to 98.7%, for CaCO 3 Scale inhibition rate is 91.3%, for CaSO 4 The scale inhibition rate is 92.8%, the light transmittance of the Fe(III) solution that characterizes the performance of dispersing iron is 17.5%, and the corrosion inhibition rate for carbon steel can reach 90.5%.
