Textile Bonded Door Drench Tester

I. Product Overview

The Textile Bonded Door Drench Tester is a specialized instrument designed to evaluate the water resistance and durability of textile-bonded doors under simulated heavy rain, flooding, or prolonged water exposure. It measures the integrity of adhesives, seams, and fabric layers when subjected to dynamic water pressure, critical for applications in construction, automotive, and industrial textiles.

• Type: Hydrostatic pressure and dynamic water jet testing system
• Test Standards: ASTM D751 (Coated fabrics), ISO 811 (Water resistance of textiles), GB/T 4744 (Chinese waterproof fabric standard)
• Key Metrics:
  • Water Penetration Depth (mm)
  • Hydrostatic Pressure Resistance (kPa)
  • Adhesive Bond Strength (N/cm²) after water exposure
• Sample Size: Up to 1200×600mm (adjustable clamping)

III. Key Features

• Dual Testing Modes:
  • Static Hydrostatic: Measures pressure resistance (e.g., flood simulation)
  • Dynamic Jet: Simulates rain impact at high velocities
• Advanced Monitoring:
  • Real-time water penetration mapping (thermal imaging)
  • AI-based bond strength degradation analysis
  • Automatic stop at failure threshold
• Automation:
  • Programmable multi-stage pressure cycles
  • Motorized sample rotation for uniform exposure
  • Self-cleaning drainage system

IV. Compliance Standards

• ASTM D751 (Coated fabrics water resistance)
• ISO 811 (Textile waterproofness)
• EN 13501-1 (Fire-resistant bonded door assemblies)
• GB/T 4744 (Chinese waterproof fabric test)

V. Applications

1. Construction: Testing fire-rated doors with textile layers
2. Automotive: Evaluating water-resistant door panels
3. Industrial: Inspecting waterproof conveyor belts and covers
4. R&D: Developing high-performance composite doors

Standard Operation Workflow:

1. Sample Preparation: Secure bonded door specimen in clamping frame
2. Parameter Setup: Select pressure mode (static/dynamic) and duration
3. Testing: Initiate water exposure cycle (e.g., 24h@300kPa)
4. Analysis: Measure penetration depth and bond strength
5. Cleaning: Automated drainage and air-drying system

Safety Precautions:

• Avoid contact with high-pressure water jets
• Use grounding straps for electrical components
• Maintain 1m clearance from drainage outlets
