General kitchen is applicable to not embroider just qualitative asphaltic Chrome plated basket. Generally can be divided into five layers of "excellent plating" technology, layer by layer, meticulous. Strict pre-treatment ensures that the coating is tightly bonded to the three layers of copper + nickel plating, isolating from electrochemical corrosion. Meet the 24 - hour acid salt spray test standard. Plating surface is flawless, anti - scratch, excellent corrosion resistance.
Only the five-storey quality process can create the top quality that is different from ordinary products:
Layer 1: Alkaline copper plating (cyanated copper plating)1-2nm (cleaning the original copper)
Layer 2: Copper pyrophosphate plating 3-5nm (enhanced adhesion)
Layer 3: Plating copper sulfate at 10nm (the density of copper acid is higher than that of copper, which plays a role in sealing cell holes on the surface of copper on the official website)
Layer 4: Nickel plating 3-5nm (anti-oxidation, anti-corrosion)
Layer 5: Chrome plated (or pearl chrome, gold)
