The mechanism of action of nano-silica dispersion:
The principle of nano-materials in improving the corrosion resistance and salt spray resistance of metals such as electroplated metal devices and coils is different from that of galvanizing, brushing protective paint, etc. Processes such as electroplating and painting cannot ensure that the corners of the device or even the main parts of the device are completely and absolutely protected by the plating or paint layer. Under a microscope, the electroplated workpiece has many ultra-fine pores (micron or even nanometer scale) exposed to the air. These unprotected defective parts will be the source of electrochemical reactions that cause the metal workpiece to rust. . Nanomaterials will use their special permeability, insulation, and reactivity to effectively target defective locations that cannot be affected by electroplating, painting, and other processes, greatly improving the corrosion resistance and salt spray resistance of metal devices.
How to use nano-silica dispersion material:
.
Use in passivation liquid: In the electroplating process, add this product directly to the passivation liquid product, stir evenly, and then use it according to the normal process. .
Directly used as sealing agent: dilute the product ~ times with pure water, and then directly soak the device after electroplating, passivation, water washing and other processes in the pure water solution, soak for about seconds, take it out and dry it That’s it. . The product can be directly added to the original passivation solution and sealing agent concentrate to improve product performance
It can also be directly added to the working solution in the electroplating process for use.
The above methods can greatly improve the corrosion resistance and salt spray resistance of metal devices. Depending on the type of process, it can generally increase the original salt spray resistance time by %~%. , Nano-silica dispersion is still an excellent anti-sedimentation material for coatings and is widely used as an anti-sedimentation agent for coatings.
