Problems solved by technology

[0013] 1) Inorganic alkali electrolyte components are consumed due to carry-out, and the active components are reduced; 2) Surfactants continue to solubilize oil and become saturated and fail; 3) The dissolved metal ions in the degreasing solution accumulate to a certain extent, resulting in the occurrence of electrode reactions in the solution 4) Due to the accumulation of pollutants in the bath, the saturation of surfactants, and the saponification of oil saponification, the washing performance of the bath drops sharply, and the pollutants are easily Sticking to the product causing quality degradation

Abstract

The invention discloses an electrolytic degreasing synergist, a preparation method and application of the electrolytic degreasing synergist. The electrolytic degreasing synergist comprises the following components: sodium hydroxide; sodium carbonate; sodium tripolyphosphate; sodium metasilicate pentahydrate; EDTA; sodium benzoate; lauryl sodium sulfate; nonylphenol polyoxyethylene ether; polyethylene glycol M600; polyethylene glycol M4000 and diethylene glycol monobutyl ether. The electrolytic degreasing synergist is used in an electrolytic degreasing process, can supplement the effective components of electrolytic degreasing bath liquid, and further can restore the performance of the aged electrolytic degreasing bath liquid, so that the purpose of continuing to use the bath liquid is achieved.

Description

technical field [0001] The invention belongs to the field of cleaning agents, in particular to an electrolytic degreasing synergist. Background technique [0002] During the electrolytic degreasing process of surface treatment, the effective components of the electrolytic degreasing tank will gradually become invalid after being used for a period of time. At the same time, the pollutants accumulated in the middle of the electrolytic degreasing tank will cause the aging and failure of the electrolytic degreasing tank, and the only solution is to replace it. On the one hand, the synergist supplements the effective components of the electrolytic degreasing bath liquid, and on the other hand removes the aged electrolytic degreasing bath liquid and restores its performance, so as to achieve the purpose of continuing to use the bath liquid. [0003] The working principle of electrolytic degreasing: the workpiece is energized in the electrolytic degreasing tank liquid, and the elec...
