Problems solved by technology

Since the law of our country stipulates that the heating of residential buildings does not allow the use of steam boilers, only hot water is allowed to be used as the heat medium, so the conventional heating boilers are all atmospheric pressure hot water boilers, and the boilers are prone to scale due to heating during use. In order to affect the normal heating of the boiler, the uneven heating may also cause the boiler to bur...

Abstract

The invention belongs to the technical field of chemical descaling treatment and in particular relates to a heat supply boiler and pipeline descaling agent which comprises the following components: anorganic acid, diethylenetriaminepenta(methylenephosphonic) acid sodium, sodium thiosulfate pentahydrate, dodecyl dimethyl benzyl ammonium chloride, an adhesive, a non-ionic surfactant, a corrosion inhibitor, an anti-rusting agent, a bactericide and a chelating agent, wherein the organic acid is weak acidity; the rusting agent is triethanolamine; the bactericide is isothiazolinone; the adhesive comprises water-soluble rubber powder, sodium metasilicate and carboxymethyl cellulose sodium; the corrosion inhibitor is a mixture of hexamethylenetetramine and sodium dodecyl benzene sulfonate; the chelating agent is ethylenediamine tetraacetic acid disodium salt or sodium pyrophosphate. The descaling agent is good in descaling effect and free of oxidation or corrosion upon a furnace, and in addition has a sterilization effect and is very safe and healthy, and equipment shutdown is not needed in the use process.

Description

technical field [0001] The invention belongs to the technical field of chemical descaling treatment, and in particular relates to a descaling agent for heating boilers and pipelines. Background technique [0002] Heating boilers are a kind of boiler products used for heating in winter. According to different heating methods, they can be divided into electric heating boilers, oil heating boilers and gas heating boilers. Since the law of our country stipulates that the heating of residential buildings does not allow the use of steam boilers, only hot water is allowed to be used as the heat medium, so the conventional heating boilers are all atmospheric pressure hot water boilers, and the boilers are prone to scale due to heating during use. In order to affect the normal heating of the boiler, the uneven heating may also cause the boiler to burst, and the scale attached to the pipeline will also affect the normal flow of hot water. [0003] Conventional descaling agents are hi...
