Embodiment Construction
[0021] This specific embodiment takes the following technical scheme: its formula composition ratio is: hydrochloric acid 20%, stabilizer 4%, reducing agent 2%, synergist 2%, chelating agent 2%, corrosion inhibitor 2%, water 68% .
[0022] The stabilizer is titanium dioxide.
[0023] The synergist is gluconic acid.
[0024] The corrosion inhibitor is hexamethylenetetramine.
[0025] The reducing agent is sodium thiosulfate, which acts to activate the outer layer of the oxide skin, and convert the high-valent metal oxides and high-valent iron salts that are difficult to react in the outer layer of the iron oxide skin into low-valent metal oxides that are easily soluble in acids. Low-priced iron salts, favorable for Fe 3 o 4 and Fe 2 o 3 dissolution and removal.
[0026] The chelating agent is ethylene glycol, and its function is to maintain the stability of the acid solution, prolong the service life of the acid solution, and at the same time promote the dissolution of t...
