Electroplating liquid with good light reflection

Abstract

The invention discloses electroplating liquid with good light reflection, which comprises a detergent, a penetrant and a softening agent, wherein the detergent is zincate; the penetrant is ammonium oxalate; the softening agent is sodium carbonate; the zincate accounts for 41-45% of the total weight of the electroplating liquid with good light reflection; the ammonium oxalate accounts for 27-29% of the total weight of the electroplating liquid with good light reflection; the sodium carbonate accounts for 27-31% of the total weight of the electroplating liquid with good light reflection. The electroplating liquid with good light reflection, disclosed by the invention, has the advantages of good light reflection, good stability of the plating liquid and high electroplating efficiency.

Description

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

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 electroplating. Hydrogen bubbles tend to adhere to the dirt and are difficult to discharge, resulting in pinholes and pitting in the coating, and as the bubbles gradually grow, the coating will automatically burst. , produces peeling phenomenon, which leads to the disadvantages of poor reflection of the plating solution, poor stability of the plating solution and low plating efficiency
