Polyvinyl Chloride (PVC) Waterproofing Membrane

1.1 Produced PVC Waterproofing Membrane Types

Homogeneous PVC Waterproofing Membrane: Single-layer PVC structure, suitable for general waterproof scenarios

Internal Reinforced PVC Waterproofing Membrane: Polyester fiber cloth or glass fiber mesh cloth added in the middle, with higher tensile strength and better stability than homogeneous type, suitable for high-demand waterproof projects

1.2 Core Characteristics of Produced PVC Waterproofing Membrane

Aging resistance: Added anti-UV agent in the formula to adapt to outdoor long-term use

Weldable: Convenient construction, strong bonding, effective avoidance of water seepage at joints

Root puncture resistance: Suitable for planted roofs and other scenarios with plant growth

Wide application: Applicable to roofs, basements, tunnels, photovoltaic roofs and other engineering fields

2. Production Process of PVC Waterproofing Membrane

The production process of Polyvinyl Chloride (PVC) Waterproofing Membrane is mature and standardized, with clear steps and easy control, ensuring stable product quality:

Batching & High-Speed Mixing: Mix PVC powder, plasticizer, stabilizer, anti-UV agent and filler → hot mixing → cold mixing → material storage, with automatic feeding function to ensure uniform mixing

Twin-Screw Extrusion Plasticization: Melt the mixed materials, exhaust and plasticize evenly, then transport the melt to the wide-width die head

Three-Roll Calendering Forming: Determine the thickness and surface smoothness of the PVC waterproofing membrane, with precise temperature control to ensure flat surface without wrinkles

Internal Reinforcement Composite (Only for Reinforced Type): Place polyester cloth or glass fiber mesh cloth in the middle, and realize one-time composite forming of upper PVC layer, middle reinforcement layer and lower PVC layer

Cooling & Shaping: Traction, edge cutting and online detection (thickness measurement, pinhole detection, tension control, deviation correction) to ensure product qualification

Automatic Winding & Packaging: Automatic winding by double-station winding machine, then packaging and warehousing, improving production efficiency

3. Core Equipment Composition

Polyvinyl Chloride (PVC) Waterproofing Membrane is composed of high-quality core equipment, with stable operation and long service life:

Twin-Screw Extruder (Main Machine): Forced exhaust, specially suitable for PVC material processing, ensuring uniform plasticization

Wide-Width Hanger Die Head: Ensure uniform width and thickness of the produced PVC waterproofing membrane

Three-Roll Calendering Unit: Mirror or matte surface optional, precise temperature control, stable thickness setting

Internal Reinforcement Unwinding Device: Realize stable unwinding of polyester cloth/glass fiber mesh cloth, with tension control function

Cooling Conveyor Frame: Traction, automatic deviation correction and edge cutting, ensuring smooth conveying of products

Online Detection Equipment: Laser thickness measurement and electric spark pinhole detection, eliminating unqualified products in time

Double-Station Automatic Winding Machine: Improve winding efficiency and ensure neat winding

PLC Full-Automatic Control System: Easy operation, precise parameter control, reducing human error
