Why is it that if you want to ensure the quality of plating, you can't ignore the water washing step in the plating process? To answer this question, we can interpret the purpose of water washing, which is to remove the impurities, residual electrolyte and reaction products on the surface of plated workpiece, and if the water washing is not complete, then what problems will be caused? In order to solve the problem, what kind of dehydrating agent should we choose?
1. Reduced adhesion: The adhesion between the plating layer and the substrate may be affected by incomplete washing. Residual impurities on the surface of the substrate may prevent uniform deposition of the plating layer, resulting in weak adhesion between the plating layer and the substrate.
2. Affects appearance: Residues may cause watermarks, spots or streaks in the plating, and these imperfections can affect the quality of the product's appearance. Appearance problems are easily noticed visually by users and may result in product returns or complaints. To solve this problem, use a dehydrating agent after washing.
3. Causes corrosion: If corrosive chemicals remain on the surface of the substrate after washing, these chemicals may slowly erode the plating and the substrate even after plating, thus reducing the service life of the plated parts.
4. Formation of air holes and inclusions: During the plating stage, uncleaned substrate surfaces may lead to air bubbles or other inclusions embedded in the plated layer, resulting in an uneven internal structure of the plated layer and affecting the physical properties of the plated layer, such as hardness and strength.
5. Uneven quality of plating layer: Because the surface is not thoroughly cleaned, plating may form uneven coverage and uneven thickness of the plating layer, which will affect the performance and life of the plated parts.
6. Current inefficiency: Insulating dirt on the surface that is not cleaned off affects the current distribution and may cause some areas to have too low or too high a current density, which in turn leads to a reduction in plating efficiency.
7. Increase the difficulty of subsequent processing: in the subsequent polishing, sandblasting or other surface treatment process, not clean impurities will increase the difficulty of work, and may damage equipment and tools.
In order to avoid the above adverse effects, the water rinsing step in the plating process needs to strictly control the water quality, temperature, flow rate, time and other factors to ensure that the surface of the substrate before and after plating is fully and effectively cleaned. Meanwhile, in order to ensure the quality of the plating layer, we can use Bigely dehydrating agent for treatment after rinsing, which can quickly complete the drying of the workpiece, so as to avoid watermarks and other faults, but also to save energy costs.
