Abstract

The invention relates to a defoaming agent for boiler water treatment and a preparation method thereof. The defoaming agent is prepared from, by mass, 3-9 parts of polypropylene glycol stearate, 75-95 parts of epoxy ethane, 2-7 parts of epoxy chloropropane, 0.5-2.1 parts of isopropyl alcohol, 1.5-4.5 parts of stearic acid, 6-13 parts of triethanolamine oleic acid soap, 0.2-0.6 part of sodium silicate, 0.2-0.5 part of didecyl dimethyl ammonium chloride, 0.6-1.5 parts of iso-tridecanol polyoxyethylene ether, 0.05-0.15 part of ammonium hydrogen fluoride, 0.4-1 part of sodium alginate, 0.2-0.6 part of manganous dihydrogen phosphate and 0.1-0.5 part of copper carbonate. The defoaming agent has excellent defoaming and foam-inhibiting effects and can effectively eliminate and inhibit foam during boiler water treatment. In addition, the defoaming agent also has rust removal, scale inhibition and corrosion mitigation effects and can be used as an adjuvant for boiler water treatment.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a defoamer for boiler water treatment and a preparation method thereof. Background technique [0002] The boiler can operate safely, economically, reliably and stably, and can produce qualified steam or hot water. Familiar with boiler water, understand the harm of poor water quality to the boiler, master the water and steam quality standards, and do a good job in boiler water treatment and necessary furnace It is extremely important to conduct chemical treatment and supervise the water and steam quality strictly according to the standard requirements in operation to ensure the water quality and steam quality of the boiler as well as the safe and economical operation of the boiler. Boiler water treatment agents generally have the functions of descaling, corrosion inhibition and cleaning. In the process of boiler water treatment, a large amount of foam will be generated, w...
