Content
Standard
- GB/T 9780-2013 (China’s national standard for evaluating stain resistance of architectural coatings via reflection coefficient analysis)
- ASTM D6578 (Standard practice for determining the resistance of synthetic polymeric materials to hydrolysis)
- ISO 11998 (Determination of wet scrub resistance and cleanability of coatings)
Product Advantages
- Precision Stain Simulation
- 1,500g ±10g friction head with adjustable speed (10–99 cycles/min) replicates real-world scrubbing conditions.
- 300mm stroke length ensures uniform stain application across 432mm x 165mm test panels.
- Automated Compliance
- Preloaded GB/T 9780-2013 protocols with automatic reflection coefficient calculations (ΔL* values).
- LCD touchscreen: Real-time display of cycles, speed, and scrubbing resistance metrics.
- User-Centric Design
- Ergonomic controls: Adjustable speed/stroke settings via rotary encoder with tactile feedback.
- Quick-release friction head: Tool-free changes for varying stain types (ink, coffee, grease).
- Data-Driven Insights
- Built-in software logs scrub cycles, *ΔL values**, and stain removal efficiency (SRE) percentages.
- Exportable reports with spectral reflectance curves (400–700nm wavelength scan).
- Industrial Durability
- Anodized aluminum frame with corrosion-resistant coating for 10,000+ hour lifespan.
- IP54 enclosure for dust/water resistance in laboratory environments.
Product Features
Stain Application:
- Dip-coating method: Immerses test panels in stain solutions (ink/coffee/grease) for 5-second adhesion.
- Scrubbing mechanism: Reciprocating friction head with 1,500g load (adjustable via sliding weights).
- Control System:
- PID closed-loop control maintains ±1 cycle/min speed accuracy.
- LCD touchscreen with embedded GB/T 9780-2013 and ASTM D6578 protocols.
- Data Analytics:
- Spectrophotometer integration port for pre/post-test reflectance measurements (ΔL* calculation).
- Automatic SRE calculation: SRE (%)=ΔLcontrolΔLcontrol−ΔLtest×100.
- Safety Features:
- Emergency stop button, overload protection (1,600g max), and anti-slip rubber feet.
- Sample Handling:
- 432mm x 165mm x 0.25mm black PVC test panels (matte finish, 85% reflectance).
