Abstract

The invention discloses a cleaning agent for a heating system, which specifically comprises: sodium edetate, thiourea, 5-chloro-2-methyl-4-isothiazoline-3-one, sodium nitrite , mercaptobenzothiazole, sodium dodecylbenzenesulfonate, hexamethylenetetramine, zinc sulfate, sodium borohydride, diethylenetriaminepentamethylenephosphonic acid, citric acid, potassium chromate, sodium alginate, The balance is water; the invention also discloses the preparation method of the cleaning agent. The use of this powerful cleaning agent can completely remove all kinds of rust spots, dirt and solidified substances attached to boilers and pipes, and a protective film can be formed on the surface of boilers and pipes after cleaning to reduce the scaling speed of boilers and pipes. The cleaning agent for heating and heating systems of the present invention has strong acidity, good water solubility, no toxicity to human body, no corrosion to boilers and pipelines, can significantly improve the thermal efficiency of boilers and pipelines, has simple preparation process, convenient operation, and safe and reliable use.

Description

technical field [0001] The invention relates to a cleaning agent, in particular to a cleaning agent suitable for heating systems, and to a processing technology of the cleaning agent. Background technique [0002] After the central heating and heating system has been used for several years, a large amount of dirt such as scale and rust will be generated in the system, which will affect the normal operation of the system, and even fail to meet the specified heating temperature requirements in severe cases. This leads to an increase in the number of system maintenance, a decrease in efficiency and a waste of energy. Removing the dirt in the system is the only effective way to solve the above problems. [0003] Typically, boiler cleaning agents are used to remove dirt from the system. The popular name of boiler cleaning agent is boiler descaling agent, as the name implies, it refers to a chemical agent that can remove scale inside the boiler. It is widely used in electric boi...
