Separated Letters Gold Metal Logos 41.Why should metals be plated? Answer:When metal is used in different environments, metal corrosion occurs due to the chemical and electrochemical effects of external agents on the metal surface. The result of metal corrosion is not only the loss of the metal itself, but also the loss of value due to damage to the structure of the metal product, resulting in a waste of human and material resources, the value of which is many times greater than the metal itself. Therefore, in the mass production of metal and metal products at the same time, it is necessary to fight against metal corrosion. Electroplating process is to increase the protective properties of metal and improve the quality of the metal surface of one of the most effective methods. Plating of metal products is to protect the metal from corrosion, improve the performance of metal products and increase the aesthetics of the product surface. Separated Letters Gold Metal Logos 42.What is the pH value of the plating solution? Answer: The pH value of plating solution refers to the acidity and alkalinity of the solution. As we know, water is a weak electrolyte, it can also be ionized.Ionization of water is very small, under normal conditions, 10 million liters of water, only one gram molecules of water ionization, that is to say, in each liter of water hydrogen ions and hydroxide ions concentration of 1/100000000 grams of equivalent, therefore, it can be said that: in the neutral aqueous solution, the concentration of hydrogen ions or hydroxide ions for 10-7 grams of equivalent.Hydrogen ions are common to acids and hydroxide ions are common to bases, so the concentration of hydrogen ions and hydroxide ions in a solution directly reflects the acidity or alkalinity of the solution. In a neutral…

Separated Letters Gold Metal Logos 36.What is the role of boric acid in nickel plating solution, if the boric acid is insufficient, what will happen? Answer: Boric acid is the buffer of nickel-plating solution, buffering the role of the pH value of the plating solution. When the concentration of 31 g / liter or more, there is a significant effect, but not too high, because the solubility of boric acid at room temperature about 40 g / liter or so. Due to the buffering effect of boric acid, so that the cathode area solution pH value does not produce a sharp change, thus allowing the use of higher cathode current density without precipitation of hydroxides on the cathode. It also has the effect of improving cathodic polarization and plating properties. However, excessive levels of it can reduce cathode current efficiency. The buffering effect is very weak when it is lower than 20g/liter, which makes the pH value of the plating solution change intensify and affects the quality of plating layer, and even makes the plating process impossible. 37.nickel plating, the pH of the electrolyte near the anode and the cathode near the pH of the electrolyte that a high, why? Answer:The pH of the electrolyte near the cathode is higher. This is due to the electrolysis process, the cathode on the precipitation of hydrogen gas and make the pH rise. 2H + + 3 → H2 ↑ Separated Letters Gold Metal Logos 38.After galvanizing the passivation layer, white passivation and color passivation layer that a good corrosion resistance? Answer:The corrosion resistance of a passivated coating after galvanizing is better with a colored passivation than with a white passivation. This is because the passivation white treatment, is already formed in the color passivation film in the bleaching solution to dissolve off…

Third. field simulation tests (user scenario replication)Artificially accelerated wearMethod: Use Martindale abrasion meter, load 9kPa pressure, evaluate after 10,000 times of rubbing.Case: A sports brand label needs to pass 2000 times of friction (simulating 1 year of daily use).Chemical corrosion testReagents: 75% alcohol, sweat simulating solution (pH 4.7-7.5), sunscreen (SPF50+).Time: No discoloration, dissolution or loss of adhesion after 24 hours of exposure.Extreme temperature difference testProcedure: -30℃ freezing for 24 hours → 60℃ baking for 2 hours, cycle 5 times.Focus: Check the bonding strength between hot melt adhesive and paint film to avoid delamination. Fourth. data analysis and improvement directionFailure mode analysis (FMEA)Common problems: insufficient adhesion of paint film (45%), poor compatibility of substrate (30%), incomplete curing (25%).Improvement case: A brand improved adhesion to 5B by adding corona treatment (dyne value ≥42).Quality control pointsIncoming material inspection: surface roughness of substrate Ra≤0.8μm (metal), Dyne value≥38 (plastic).Process monitoring: spraying thickness 20-30μm (wet film), curing temperature ±5℃, time ±10%.Finished product inspection: 10% sampling inspection for each batch, non-conforming products should be traced back to the previous 3 processes.Fifth. industry practice casesLuxury labels: UV curing ink + thermal transfer process, passed 3M 810 tape test (adhesion 15N/25mm).Outdoor equipment labels: add polyurethane varnish layer, passed 1000 hours QUV test.FMCG labels: Optimize water-based ink formulation, pass 24 hours sweat immersion test.Conclusion: Detecting whether a Brand tag loses its paint requires a combination of basic laboratory tests (e.g., scratch method, abrasion test) and environmental simulation tests (e.g., humidity, heat, salt spray, UV aging), as well as field simulations (artificial abrasion, chemical corrosion). Optimizing process parameters (e.g., substrate treatment, curing conditions) through failure mode analysis can significantly improve label durability. Industry practice has shown that the use of high adhesion inks, the addition of protective coatings and strict process control are key.
