Pickling Systems
Etching is a chemical or electrochemical process that dissolves the surface of metals to remove scale and oxides using acid and alkali solutions. Electrochemical etching is used to accelerate the etching process and in cases where chemical etching is difficult or impossible. For parts that require the preservation of precise geometric dimensions, electrochemical etching is recommended. Additionally, compared to chemical etching, the electrochemical process is more economical due to lower reagent consumption.
Pickling Systems
During the manufacturing and storage processes, metal products are exposed to environmental elements that can lead to the accumulation of corrosion products or thermal scale on their surfaces. This not only detracts from the visual appeal of the products but also hinders the effectiveness of subsequent manufacturing processes.
Cleaning and Preparing Metal Surfaces
Before applying any galvanic coatings, it's essential to thoroughly cleanse the products' surfaces of all contaminants, including oxides, in dedicated degreasing baths. To remove oxides and thermal scale, the surfaces undergo treatment in pickling systems. These systems are designed specifically for the deep cleaning of metals, utilizing acidic solutions to strip away unwanted residues and prepare the metal for further processing, such as plating.
The Role of Pickling Systems in Metal Treatment
Pickling systems play a crucial role in the preparation of metal surfaces for cadmium plating, a common method used to protect against corrosion. By ensuring that all oxidation and scale are effectively removed, these systems help in achieving a cleaner and more receptive surface for the plating process.
Material Selection for Durability and Efficiency
For the construction of tanks (previously referred to as baths) used in etching, cadmium plating, and degreasing, polypropylene is the preferred material due to its robust properties. Polypropylene is not only chemically resistant but also wear-resistant and capable of withstanding temperatures up to 85°C without mechanical stress. It is highly resistant to many acids and alkalis, even at high concentrations, making it ideal for harsh chemical environments found in pickling systems.
Structural Components of Galvanic and Pickling Tanks
The bodies of these tanks are crafted from chemically resistant polypropylene homopolymer (PPH). The frameworks supporting these tanks, including the underframes, are typically made from steel coated with a chemically resistant enamel to enhance durability and chemical resistance.
In addition to the structural integrity, the tanks are equipped with various functional accessories to facilitate the pickling and plating processes:
Using advanced materials like polypropylene and incorporating efficient designs, modern pickling systems and galvanic tanks are critical in preparing metal surfaces for further processing. By ensuring thorough cleaning and preparation, these systems contribute significantly to the quality and longevity of metal coatings, which are essential in many industrial applications.

- Katie:Why is a Pickling Systems tanks so good?Support:Pickling systems' tanks play a crucial role in metal processing industries by preparing metal surfaces for further finishing, such as painting, coating, or galvanizing. These tanks, often made from materials like polypropylene or stainless steel, are designed to hold acidic or alkaline solutions used for the chemical cleaning of metals. Here's why these tanks are so effective and valuable:
1. Effective Surface Preparation
Pickling is a process that involves removing impurities such as rust, scale, and other contaminants from metal surfaces. This is essential for ensuring that subsequent coatings adhere properly and perform as expected. Pickling tanks allow for the thorough and uniform treatment of metal parts, ensuring that surfaces are perfectly prepared for the next steps in the manufacturing process.
2. Material Compatibility
Pickling tanks are typically made from materials that are resistant to the corrosive nature of pickling solutions, such as polypropylene, PVDF, or stainless steel. These materials ensure that the tanks can withstand prolonged exposure to aggressive chemicals without degrading, thereby extending the lifespan of the tanks and reducing the need for frequent replacements.
3. Customization and Versatility
The design of pickling tanks can be customized to meet specific industrial needs, including various sizes and shapes depending on the parts to be treated and the volume of production. This versatility makes them suitable for a wide range of applications across different industries, including automotive, aerospace, and construction.
