Z-2 Form Adjustment

Product Features:
★ This product is a titanium-based surface conditioner with high activity and efficiency. It forms a dense titanium nucleus on the workpiece surface, resulting in a uniformly crystallized and compact phosphating film, accelerating the phosphating reaction while also neutralizing residual acid pickling solutions. This enhances the corrosion resistance of the metal.
When used in conjunction with the HH-DW film-forming agent, specifically HH-DW-1, it results in a dense phosphating film, enhancing paint adhesion and corrosion resistance.

Product Details
Z-2 surface conditioning induces microscopic changes on the metal surface, thereby significantly enhancing the phosphating performance and promoting the formation of a uniform, dense phosphating film.

Precautions
How to use
1. Process Flow
Pre-degreasing → Main degreasing → Water rinsing → Water rinsing → Surface conditioning → Phosphating → Water rinsing → Water rinsing → Passivation → Drying
2. Preparation of the surface-conditioning working solution (based on 1,000 liters)
① Fill the treatment tank to 80% with clean water;
② Add 2–3 kg of Z-2 type and stir until completely dissolved and evenly dispersed;
③ Add clean water to a total volume of 1,000 liters and stir thoroughly;
3. Top-up and Adjustment: (based on 1,000 liters)
Due to continuous changes in concentration during the plating process, the bath solution must be regularly analyzed to monitor its condition and promptly replenished and adjusted to maintain optimal operating parameters. Typically, when the pH falls below 8, a corrective addition is required—usually half the amount used for the initial bath preparation—to bring the pH back within the specified process range. If the bath has been in use for an extended period and exhibits yellowing, turbidity, or an off odor, the entire bath should be discarded and replaced with a fresh solution.
Precautions
1. It is best to prepare the solution using deionized water to prevent the active ingredients from precipitating and thereby reducing the service life.
2. When performing impregnation treatment, it is essential to maintain the stability of the bath composition; thorough stirring of the solution is crucial to prevent the precipitation of active ingredients.
3. It is best to keep the working solution temperature below 40°C to prevent excessive precipitate formation.
4. In general, the plating bath does not require testing; it will lose effectiveness after a period of use.
