Abstract

The solid neutral green chemical cleaning scale remover consists of urotropin 5-20 weight portions, sodium salicylate 2-10 weight portions, sodium succinate 5-20 weight portions, and sodium hydroxyl acetate 5-15 weight portions, and may have fatty amine 5-20 weight portions and liquiritigenin sodium 5-15 weight portions. It is prepared through mixing in the said weight proportion and stirring. It features the neutrality, solid state, environment friendship and fast scale and rust removal. It may be used widely in eliminating scale and rust in various kinds of production apparatus.

Description

technical field [0001] The invention belongs to the technical field of chemical cleaning, and in particular relates to a solid neutral chemical cleaning and descaling agent and a preparation process thereof. Background technique [0002] At present, the chemical cleaning industry in my country is mostly pickling, which is divided into inorganic acid and organic acid cleaning agents. Commonly used inorganic acid cleaning agents are strong acid cleaning agents such as hydrochloric acid and nitric acid. Strong acid cleaning agents have strong scale dissolution ability, high cleaning efficiency, and low cost. They are suitable for cleaning large-scale and heavy-duty equipment. Strong toxicity and high toxicity, the whole cleaning process consumes water, labor and time, pollutes the environment, has certain dangers to both equipment and operators, and has many inconveniences in transportation and storage. In addition, due to the strong corrosiveness of strong acid cleaning agent...
