Abstract

The invention discloses a boiler disincrustant which is prepared from the following raw materials in parts by weight: 5-9 parts of coconut oil ethoxylate, 15-20 parts of sodium dodecyl benzene sulfonate, 2-5 parts of coconut oil diglycollic amide, 1-3 parts of sodium ethylenediamine tetraacetic acid, 3-8 parts of triethanolamine, 1-3 parts of dodecyl phosphate and 60-70 parts of water, wherein the dodecyl phosphate is dodecyl phosphate sylvite or sodium salt. The final pH value of a product of the boiler disincrustant disclosed by the invention is within 7.5-8, so that no corrosion is caused to boiler walls, human skin is not hurt when the boiler disincrustant is used, and the security in operation is improved. Besides, the coconut oil ethoxylate and the coconut oil diglycollic amide added into the product are high in dissolving capacity on boiler dirt and rapid to contaminate.

Description

Technical field [0001] The invention belongs to the technical field of detergents, and specifically relates to a boiler descaling agent. Background technique [0002] After the boiler has been running for a long time, the problems of scale and rust will inevitably appear. The main reason for the boiler scale formation is the hardness of the feed water. After the continuous evaporation and concentration of high temperature and high pressure, a series of physical and chemical reactions occur in the furnace. The reaction will eventually form hard and dense scale on the heated surface. Scale is the "first of all hazards" of boilers and the main cause of boiler accidents. Regularly cleaning the boiler dirt can save fuel, reduce overall equipment maintenance costs, and extend the service life of the equipment. At present, most of the boiler cleaning is carried out by pickling or alkaline washing, and then rinsed in clean water. The operation is cumbersome and the acid and alkali w...
