Example Embodiment
[0031] A method for preparing a circulating water corrosion and scale inhibitor, which includes the steps:
[0032] In S100, the respective components of the corresponding mass percentages are stirred for 30 minutes at room temperature and pressure, and mixed evenly to obtain a mixture; and
[0033] In S200, the mixture is placed in a reactor equipped with ultrasonic waves and processed under the action of ultrasonic waves to prepare the circulating water corrosion and scale inhibitor.
[0034] Wherein, the power of the ultrasonic wave in the step S200 is 100w˜500w, and the processing time of the ultrasonic wave is 2h˜5h.
[0035] Preferably, the power of the ultrasound is 300w, and the processing time of the ultrasound is 3h.
[0036] The circulating cooling water corrosion and scale inhibitor has a wide range of raw material sources, low production costs, and can achieve excellent corrosion and scale inhibition effects at a relatively low concentration during use, further saving treat...
Example Embodiment
[0040] Example one
[0041] The mass percentage of the raw materials of the circulating water corrosion and scale inhibitor is: 20% polyacrylamide, 15% 2-hydroxyphosphonic acid, 5% polyepoxysuccinic acid, 10% anthocyanin, 20% tea Phenol, 10% melamine, 20% isophorone diamine, and the rest is a mixed solution of ethylene glycol and water. After mixing the above-mentioned components uniformly, and treating for 3 hours under the action of 300w ultrasonic wave, the measured corrosion inhibition rate is 85.2%, and the scale inhibition rate is 82.3%.
