Abstract

The invention relates to the technical field of electroplate liquid, in particular to a stable electroplate liquid. The stable electroplate liquid comprises blue copperas, sulfuric acid, hydrochloricacid, an accelerator and a wetting agent; the accelerator is a mixture of one or more mercaptan compounds; the wetting agent is a mixture of one or more polyalcohol compounds; and the concentration ofthe blue copperas of the stable electroplate liquid is 70-85 g/L, the concentration of the sulfuric acid is 96-108mL/L, the concentration of the hydrochloric acid is 44-65mg/L, the concentration of the accelerator is 0.5-0.9mL/L, and the concentration of the wetting agent is 13-20mL/L. The stable electroplate liquid has the advantages of good stability, high uniform coverage ability and fast electroplating speed, and can be used in various industrial plating fields.

Description

technical field [0001] The invention relates to the technical field of electroplating solution, in particular to a stable electroplating solution. Background technique [0002] In the process of mechanical processing, the rust-proof grease, cutting fluid grease, mechanical grease, lubricating grease, grinding fluid, mold release agent, etc., which are usually adhered to the surface of the parts, are mixed with dust and grinding dust, forming a relatively thick dirt. If the above dirt is not removed in time before heat treatment, the dust and dust attached to the parts will be inconvenient to remove oil and rust after quenching and sintering into stubborn solid grease. pinhole. In addition, when the mesh belt type resistance furnace is used for quenching, the oil stains on the surface of the parts and dust and other impurity particles are mixed together and sintered into stubborn solid grease. It is difficult to completely remove the above dirt during electroplating. Hydro...
