Determining the Dynamics of Wet Expansion of Paper by means of one-sided Liquid Contact with Adjustable Tension

Now with integrated measuring of the humidity (paper and environment), better sample mounting, newPC-Software V2.x

• Measurement of the dynamics of the change in dimension of paper by means of one-sided contact with water based liquids under adjustable tension
• Main applications:
  • Decor paper in contact with:
    • Water
    • Melamine Resin
    • Gravure ink
  • Coating base paper, newsprint paper, offset printing paper, label paper, ink jet-paper, liner board etc. in contact with:
    • Water
    • Fountain solution
    • Ink jet-ink
• Main user:
  • Paper producer
  • Chemical Supplier
  • Converter of Paper
• Replacing classical wet expansion methods with two-sided liquid contact
• Measuring range
  • Wet expansion to a maximum of 25%, measuring duration unlimited
  • Recording the expansion from the moment of liquid contact, displaying the results from approx. 100 ms after initial contact
• Measuring result
  • Expansion-time diagram
  • Expansion value at a free selectable time point
• Benefits
  • Fast contacting of the paper and liquid, important especially for high absorbent paper
  • Real trial conditions by adjustable tightness
  • Objective measuring method, free of subjective errors
  • High reproducibility of the results: ±0.05% of result
  • Accuracy better than ± 0,1% abs. ± 5% of the analytical value in the area of 0 to 3% stretching
  • Resolution approx. ± 0,013%
  • Easy handling
  • Integrated measurement of paper moistness and humidity, ambient temperature
• Software
  • Convenient user interface for measurements
  • Easy to handle in quality assurance
• Technical data
  • Sample dimension: min. 210mm x (60±0.5)mm
  • Dimension: 300 x 280 x 320mm (H x W x D)
  • Weight: 8.5 kg
  • Power supply: 230V, 50Hz / 115V, 60Hz
