Abstract

The invention belongs to the technical field of chemical cleaning of boiler pipelines, and particularly discloses a boiler pipeline descaling agent and a preparation method thereof. The descaling agent mainly consists of the following components in percentage by weight: 12 to 15 percent of aminosulfonic acid, 3 to 6 percent of hydrofluoric acid, 3 to 5 percent of acid washing corrosion inhibitor and the balance of water. The method comprises the following steps of: (1) taking water, adding the aminosulfonic acid and the hydrofluoric acid, and then stirring the solution uniformly; (2) adding the acid washing corrosion inhibitor into the solution of the (1), and then stirring the solution uniformly; and (3) adding water into the solution of the (2) till the total volume meets the requirement of 100 percent, and stirring the solution uniformly to obtain a finished product. Proved by a large amount of scientific experiments and years of internal practice application, the descaling agent not only has good cleaning and descaling effects, but also overcomes the defect of metal corrosion.

Description

technical field [0001] The invention belongs to the technical field of chemical cleaning for boiler pipe descaling, and in particular relates to a boiler pipe descaling agent and a preparation method thereof. Background technique [0002] The boiler is responsible for providing steam and hot water to users to ensure the normal heat demand of users for production, heating, bathing and so on. Although different boilers have different shapes, their construction materials are mainly composed of carbon steel. [0003] Due to the water quality, after the boiler has been used for a long time, there will be scale, rust and other dirt on the inner wall of the boiler, the smoke pipe, and the cold water wall pipe. In addition, due to the deterioration of heat transfer, it will also lead to overheating of the metal. Under the action of boiler pressure, the smoke pipes and cold water wall pipes in the furnace will be blocked, bulged, perforated, and even explosion accidents will occur; ...
