All supplier products

Application

Functional Textile R&D: Assesses air-purifying, health-enhancing, and antimicrobial fabrics.
Quality Control: Verifies compliance with negative-ion standards for medical textiles, bedding, and apparel.
Certification Laboratories: Provides data for GB/T 30128-2013 certification.

Precision Ion Detection: Capacitive suction method captures ions with mobility >0.15 cm²/(V·s).
Multi-Range Measurement: Three ranges (0–20,000; 0–200,000; 0–2,000,000 units/cm³) adapt to diverse materials.
Automated Friction System: PLC-controlled discs (93 ±1 r/min) simulate real-world wear.
Standard Compliance: Meets GB/T 30128-2013 for reliable certification.
Sample Versatility: Tests coated/uncoated fabrics, knits, and nonwovens with adjustable pressure (7.5 ±0.2 N).
Real-Time Data: Generates ion concentration curves over time for dynamic analysis.

Dual Friction Disc Design:
- Upper Static Disc: Diameter 100 ±0.5 mm (fixed).
- Lower Dynamic Disc: Diameter 200 ±0.5 mm (rotating at 93 r/min).
Capacitive Ion Sensor: High-sensitivity detection of activated negative ions.
Adjustable Parameters:
- Friction speed (93 ±1 r/min).
- Applied pressure (7.5 ±0.2 N).
Sample Fixation: Clamping devices secure samples to discs, ensuring full coverage. Gaskets prevent slippage (coated fabrics rub coated surfaces).
Enclosed Test Chamber: (300 × 560 × 210 mm) minimizes external interference.
Automated Control: PLC-driven system with touchscreen operation.
