SBS and App Bitumen Waterproof Membrane Production Line

The SBS and APP Bitumen Waterproof Membrane Production Line by Haiming Machinery integrates base material, modified bitumen coating, and surface finishing processes to achieve efficient and stable production. The line features PLC automatic control and can easily switch between SBS and APP formulas to meet different climate and project requirements.

Production Line Structure and Process

1. Structure Components

• Base Material: Polyester (PY), Fiberglass (G)
• Modified Bitumen Coating: SBS / APP powder + filler + anti-aging additives
• Surface Finish: Top surface: PE film / sand / shale, Bottom surface: PE release film

2. Production Process

1. Asphalt Melting & Storage: Heating, dehydration, and temperature maintenance
2. Modified Bitumen Preparation: High-speed colloid milling for uniform dispersion
3. Base Material Unwinding & Drying: Preheating and flattening to ensure alignment
4. Coating & Laminating: Double-sided coating with precise thickness control
5. Surface Finishing: Sanding, shale application, or PE film covering
6. Cooling & Setting: Water or air cooling for stabilization
7. Cutting, Rolling & Stacking: Automatic final product handling
