Problems solved by technology

In addition, when the mesh belt resistance furnace is used for quenching, the oil stains on the surface of the workpiece are mixed with dust and other impurity particles, and sintered into stubborn solid grease. When the nitrate is tempered, the above grease and nitro salt form stubborn thermal polymer , It is difficult to completely remove the above dirt during electroplat

Abstract

The invention discloses a non-toxic electroplating liquid. The non-toxic electroplating liquid consists of a hydrogen peroxide stabilizer, a silicon removing agent and a color fixing agent, wherein the hydrogen peroxide stabilizer is a polyethylene polyamine salt; the silicon removing agent is magnesium silicate; the color fixing agent is epoxy chloropropane; the polyethylene polyamine salt accounts for 41 to 42 percent of the total weight of the non-toxic electroplating liquid; the magnesium silicate accounts for 31 to 32 percent of the total weight of the non-toxic electroplating liquid; the epoxy chloropropane accounts for 26 to 27 percent of the total weight of the non-toxic electroplating liquid. The non-toxic electroplating liquid provided by the invention has the advantages of being non-toxic, high in stability and suitable for continuous operation.

Description

technical field [0001] The invention relates to an electroplating solution, in particular to a non-toxic electroplating solution. Background technique [0002] During the machining process, the anti-rust grease, cutting fluid, machine oil, lubricating grease, grinding fluid, mold release agent, etc. adhered to the surface of the parts are mixed with dust and grinding dust to form thick dirt. If the above dirt is not removed before heat treatment, it will be hard to clean after quenching and sintering into stubborn solid oil and rust, and bubbles will adhere to it during plating to form gas retention pinholes in the coating. The surface of the heat treatment workpiece will inevitably adhere to a layer of oil. When the dust falls on the surface and mixes with the grease, it will be difficult to clean it after a long time, so that the surface of the workpiece will form small oil spots that are not obvious. When air bubbles stay on it, pinholes are formed. In addition, when th...
