Degreasing Tank for Metal Pretreatment

Product Specifications

Technical details and manufacturing context for Degreasing Tank

Definition

A degreasing tank is a critical component within industrial pretreatment systems, specifically designed to prepare metal surfaces for subsequent coating, painting, or finishing processes. It functions by immersing or spraying workpieces with specialized cleaning solutions (alkaline, acidic, or solvent-based) to dissolve and remove organic contaminants, rust inhibitors, and shop soils, ensuring optimal adhesion and quality of the final surface treatment. The tank is typically constructed from materials such as stainless steel (e.g., 304, 316L), carbon steel with protective linings (rubber, PP, FRP), or polypropylene (PP), selected based on the chemical compatibility and operating temperature. Key parameters include tank capacity (500–5000 L), working temperature (60–90 °C), heating power (9–36 kW), and agitation speed (30–120 rpm). The tank may be equipped with insulation (50–100 mm) to reduce heat loss, and temperature control accuracy of ±2 °C ensures consistent performance. Electrical supply is three-phase, 380 V AC ±10% (IEC 60038), with degree of protection IP54–IP65 (IEC 60529). Overall dimensions and empty weight vary with capacity; for a 1000 L tank, typical dimensions are 2000×1200×1500 mm and weight 500–1500 kg. Maximum operating pressure is low (0.1–0.3 MPa) for closed tanks with agitation. These values are reference ranges and must be verified with the manufacturer for specific models. Standards listed (e.g., ASTM A240 for material) are procurement references, not certifications. Always confirm model-specific values and standards with the legal manufacturer or supplier before purchase.

Working Principle

The tank operates by containing a heated cleaning solution. Workpieces are immersed or conveyed through the solution, where surfactants and alkaline agents emulsify and saponify oils and greases. Agitation (mechanical, ultrasonic, or spray) enhances cleaning action. The contaminants are either separated via skimming, filtration, or settled as sludge, while the cleaned parts proceed to the next rinsing or treatment stage. The process is controlled by temperature, agitation speed, and chemical concentration to achieve effective degreasing without damaging the substrate.

Frequently Asked Questions

What materials are used for degreasing tanks?

Common materials include stainless steel (e.g., 304, 316L), carbon steel with rubber, PP, or FRP lining, and polypropylene (PP). Selection depends on chemical compatibility and operating temperature.

What is the typical working temperature range?

The working temperature is typically 60–90 °C. Higher temperatures accelerate degreasing but may affect chemical stability, so it must be controlled within the specified range.

How is the tank capacity determined?

Tank capacity ranges from 500 to 5000 liters, selected based on batch size and part dimensions. Larger capacities are suitable for bigger workpieces or higher throughput.

What electrical supply is required?

The tank requires a three-phase electrical supply of 380 V AC ±10% (50/60 Hz) per IEC 60038. The degree of protection is IP54–IP65, ensuring resistance to dust and water splashes.
