Criterios

• 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

1. 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.

• 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.

• 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).

• Built-in software logs scrub cycles, *ΔL values**, and stain removal efficiency (SRE) percentages.
• Exportable reports with spectral reflectance curves (400–700nm wavelength scan).

• 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).
• Sistema de control:
• 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).
