| titleOfInvention | Multifunctional environment-friendly rare earth cleaning agent and preparation method thereof |
| abstract | The invention belongs to the technical field of metal surface cleaning agents, and particularly relates to a multifunctional environment-friendly rare earth cleaning agent and a preparation method thereof. The multifunctional environment-friendly rare earth cleaning agent comprises the following components in percentage by weight: 2-10% of sulfamic acid; 3-18% of organic carboxylic acid; 0.1-2% of fatty alcohol-polyoxyethylene ether; 1-5% of a corrosion inhibitor; 0.1-2% of rare earth nitrate; the remaining amount of water. The rare earth cleaning agent has high descaling efficiency and low corrosion rate through the synergistic effect of various components such as sulfamic acid, organic carboxylic acid, surfactant, corrosion inhibitor, rare earth nitrate and the like. The cleaning agent has wide application range and can be used for cleaning heat exchangers, coolers, reaction kettle jackets, circulating water systems, motor coaches and high-speed rail equipment. The residual liquid amount of the cleaning agent after cleaning is low, and the waste liquid after cleaning is used as a raw material of a fertilizer. The rare earth fertilizer is beneficial to the growth and development of plants. |
