Advantages of Zinc Electroplating Alkaline Zincate Additives
Advantages of Zinc Electroplating Alkaline Zincate Brightening Agent
Higher brightness and glossiness: Brighteners can significantly enhance the reflectivity and brilliance of the plated surface, making it more visually appealing and reflective.
Improved leveling and coverage: Brighteners can help reduce surface defects such as pits, scratches, and unevenness, resulting in a more uniform and smooth deposit.
Reduced hydrogen embrittlement: Brighteners can minimize the risk of hydrogen embrittlement, a common problem in high-strength steel, by controlling the hydrogen evolution rate during plating.
Increased throwing power: Brighteners can improve the distribution and deposition of metal ions in complex-shaped parts, resulting in a more uniform thickness and coverage.
Effective contaminant removal
Zinc electroplating alkaline zincate cleaning agent excels at removing solid contaminants, grease, oils, fats, and other organic substances, making it ideal for heavy-duty cleaning tasks.
Neutralization of acidic soils
The alkaline nature of HL-936 helps neutralize acidic substances and contaminants, making it effective for cleaning surfaces soiled with acidic residues.
Good detergency
HL-936 exhibits good detergency, meaning it effectively lifts and removes dirt and grime from surfaces.
Safe on soft metals
Zinc electroplating alkaline zincate cleaning agent, like HL-936, are generally safe on soft metals, making them suitable for a wide range of applications.
Ease of automation and handling
Zinc electroplating alkaline zincate cleaning agent like HL-936 can be easily automated and are typically safer to handle than other types of cleaning agents.
Prevents rust and corrosion
Zinc plating, which often uses alkaline cleaning agents like HL-936, creates a protective barrier against moisture and corrosion, extending the lifespan of the underlying metal.
The preparation of cyanide plating solution must follow the operation procedure of using poison .
● Pour the calculated amount of sodium hydroxide and sodium cyanide into the preparation tank, add 1/4 of the total volume of water, stir thoroughly to dissolve;
● Adjust the calculated amount of zinc oxide into a paste, slowly add it into the hot bath under constant agitation, stir until it is completely dissolved;
● Dilute to the total volume (then stir with water), add sodium sulfide 0.1-0.3g /L, stir for 10 minutes to allow it to fully react, remove metal impurities;
● Add additives according to the instructions, stir thoroughly, use 0.5-1a /dm2 low current density electrolytic treatment for 3-4 hours, trial production can be put into production after qualified.
Preparation of HL-936 Alkaline Zincate Cleaner Electroplating Solution
Preparation of plating solution for zinc oxide purity requirements of more than 98% industrial grade, sodium hydroxide to use more than 95% purity of solid alkali.
●Pour the calculated amount of sodium hydroxide into the tank.
●Into the total volume of 1/5 of the water (with hot water in winter) quickly stir dissolved, become transparent.
●Weigh the calculated amount of zinc oxide, water into a paste,
●Gradually add to the hot lye with constant stirring until it is completely dissolved.
●The plating solution in stirring slowly add water to the total volume of 2/3. (residual volume plus additive)
●When the plating solution is cooled to 40 degrees below, add 2-3 grams/l zinc powder and stir fully for 15-20 minutes.
●No zinc powder can be 0.2g/l of sodium sulfide instead, dissolve first, and dilute several times behind add edge stirring evenly added to the plating solution, standing for 4-8 hours after filtration.
Add additives according to the requirements of the process specification, electrolytic 4-8 hours under the condition of 0.1-0.2A /dm2 current density, trial production, and put into normal production after qualified products.
Packing specifications: 25kg/plastic drum on pallet, 200kg/plastic drum on pallet, 1000kg/plastic drum on metal pallet
