Abstract

The invention provides a derusting agent for mechanical equipment and a preparation method thereof. A formula of the derusting agent for the mechanical equipment comprises lauryl sodium sulfate, alkylphenol polyoxyethylene ether, urotropine, sodium bicarbonate, a surface protectant, a surfactant, a chelating agent, deionized water, and an alkaline-resistant penetrant. The derusting agent is usedfor the mechanical equipment, and has the advantages that the existing formula of the derusting agent is improved and adjusted; the derusting effect is good; a protective film is formed at the surfaceof the derusted machine, the secondary protection is formed at the surface of the machine, and the protection function is enhanced.

Description

technical field [0001] The invention belongs to the technical field of rust removers, and in particular relates to a rust remover for mechanical equipment and a preparation method thereof. Background technique [0002] After mechanical equipment has been in normal operation for a period of time, reverse osmosis membrane elements will be polluted by suspended solids or insoluble salts that may exist in the feed water, the most common of which are calcium carbonate precipitation, calcium sulfate precipitation, metal oxide precipitation, silicon Sediments, inorganic or organic sediment mixtures, synthetic organics. In particular, the surface rust pollution of equipment that is often in contact with solvents such as water is serious. Therefore, a rust remover with good performance is indispensable. Most of the cleaning agents for mechanical equipment in the prior art are aimed at oil and rust. The effect is not high, and some cleaning agents contain harmful substances such as n...
