Innovative and Professional Chemical Cleaning Line for High-Performance Metal Surface Polishing

Equipment Description:

I. Principles of Chemical Polishing

Corrosion Selectivity: Chemical polishing achieves smoothing by preferentially dissolving raised areas of a metal surface with a chemical solution. Its key principle is that the dissolution rate of microscopically high (more active) surface ridges is significantly higher than that of concave areas, ultimately resulting in a smooth surface.
The process consists of two stages: Macro-smoothing (removing roughness at micrometer-level) and Micro-glossing (removing crystallographic defects at submicrometer-level).
Reaction Mechanism: Acidic components in the polishing solution react with the metal to form an easily peelable passivation film or dissolution products. Mechanical flow removes the reactants, preventing localized accumulation.
Additives (such as corrosion inhibitors and oxidants) regulate the reaction rate to prevent excessive corrosion or pitting defects.

II. Typical Applications and Process Parameters

Parameters/Components	Characteristics
Polishing Fluid Composition	Phosphoric acid + nitric acid + sulfuric acid (stainless steel) or tri-acid system (aluminum alloy)
Operating Temperature	Stainless steel: 80-100°C; aluminum alloy: 90-110°C
Polishing Time	1-10 minutes (depending on workpiece material and roughness)

III. Maintenance and Optimization

Bath Management: Regularly check the acid concentration (e.g., nitric acid ≤ 15%), replenish the oxidizer, and remove any deposits (every 1-3 weeks). Avoid the accumulation of metal ions (e.g., Fe₃⁺) to prevent the polishing fluid from becoming ineffective.
Equipment Maintenance: Inspect seals (NBR/fluororubber) for aging and replace them to prevent leakage. Acid clean the titanium alloy heating tubes quarterly to remove the passivation layer and maintain heat transfer efficiency.

Main Structures and Components:

I. Core Structure

Tank Body: Typically made of corrosion-resistant materials such as polypropylene (PP), polyvinyl chloride (PVC), or titanium alloy. Some tanks feature a double-layer structure to enhance mechanical strength and chemical resistance.
Temperature Control System: Tank temperature is controlled via steam, electric heating, or an internal titanium alloy coil. The typical operating temperature range is 80-100°C.
Electrode System: The anode and cathode rods are fixed to either side of the tank or on a removable frame, allowing for adjustable spacing to accommodate varying workpiece polishing requirements.

II. Auxiliary Systems

Polishing Fluid Circulation: Optional PP filter bags or activated carbon adsorption systems are available to remove particulate matter and organic matter generated during the polishing process.
Safety and Control System: An acid-resistant exhaust system is connected to quickly exhaust corrosive gases, reducing environmental hazards. Integrated temperature sensors and liquid level controllers are available.

III. Applications and Compatibility

Applicable Scenarios: Supports processes such as triple-acid polishing of aluminum alloys and chemical polishing of stainless steel. Particularly suitable for localized treatment of complex workpieces.
Maintenance Tips: Regularly clean sediment from the tank bottom (every 1-3 weeks), inspect seals for aging and replace them (made of NBR or fluororubber).
