الخصائص الميكانيكية النموذجية

Because of its excellent workability and corrosion resistance, 3003 aluminum has become the most commonly used alloy for insulation jacketing.

2.2 What Is Polysurlyn Film?

Polysurlyn film is a specialized multilayer moisture barrier bonded to the inner surface of aluminum jacketing.

Although aluminum naturally resists corrosion, prolonged moisture exposure beneath insulation systems can create localized corrosion conditions.

Combining 3003 aluminum with Polysurlyn film provides:

• Additional moisture protection
• Reduced corrosion under insulation (CUI)
• Improved insulation system reliability
• حياة الخدمة الممتدة
• Lower maintenance costs

نتيجة ل, the product has become a standard material in industrial insulation specifications worldwide.

3. Understanding the Polysurlyn Moisture Barrier

3.1 Typical Barrier Structure

A typical structure includes:

Some products may use a stucco embossed outer surface.

This embossed finish can reduce glare, hide small scratches, and improve handling stiffness.

3.2 Function of Polysurlyn Film

Polysurlyn film improves insulation jacketing performance in several ways:

• Reduces direct contact between aluminum and wet insulation
• Helps lower the risk of underside pitting
• Provides a barrier against trapped moisture
• Helps reduce galvanic corrosion when dissimilar metals exist nearby
• Improves service reliability in humid or outdoor environments
• Offers a cleaner, more durable backing than kraft paper in many systems

CUI often develops when water collects in insulation and contacts metal surfaces.

Public corrosion references describe CUI as localized corrosion linked to water absorption or water collection inside insulation systems.

A moisture barrier does not eliminate every corrosion risk, but it adds an important protective layer.

5. Polysurlyn Film Aluminum Coil Composite Process

The composite process focuses on bonding the film securely to the aluminum coil without wrinkles, bubbles, تلوث, or weak adhesion.

تشمل الخطوات الرئيسية:

1. Aluminum surface preparation
   The aluminum surface must be clean and dry before lamination. Oil, تراب, or metal fines may reduce bonding strength.
2. Film feeding and alignment
   The Polysurlyn film is aligned with the aluminum coil to avoid offset, edge mismatch, or wrinkles.
3. Thermal lamination or bonding
   Controlled heat and pressure help bond the film to the aluminum surface.
4. Tension control
   Proper line tension prevents wrinkles, تمتد, and trapped air.
5. Cooling and stabilization
   The laminated coil cools before rewinding to stabilize bonding quality.
6. تقتيش
   Operators check film adhesion, surface appearance, edge quality, and coil winding condition.

A well-controlled composite process helps the material survive cutting, الانحناء, المتداول, and field installation.
