WSD 02 - Wet Stretch Dynamics Analyzer

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

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
- Gypsum board, 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 27%, 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
