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 electrop

Abstract

The invention discloses electroplating liquid with good stability. The electroplating liquid with good stability comprises a dispersant, a water reducing agent and a silane coupling agent, wherein the dispersant is sodium dodecyl sulfate, the water reducing agent is polycarboxylic acid, the silane coupling agent is butadiene triethoxy silane, the sodium dodecyl sulfate accounts for 35-45% of the total weight of the electroplating liquid with good stability, the polycarboxylic acid accounts for 22-33% of the total weight of the electroplating liquid with good stability, and the butadiene triethoxy silane accounts for 30-36% of the total weight of the electroplating liquid with good stability. The electroplating liquid with good stability, provided by the invention, has the advantages of good stability, excellent uniform coverage ability and high electroplating speed.

Description

technical field [0001] The invention relates to an electroplating solution, in particular to an electroplating solution with good stability. 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 additi...
