emco DPM 66 Dynamic Penetration Measurement

The dynamic penetration measurement of emco is based on absolute, calibrated ultrasonic transmission measurement. It is used as an innovative method for analysis of the nature of paper and other materials, liquids and the dynamic of their interaction.

Features

  • Absolutely calibrated measurement values in decibel
  • Fully automatic measurement sequence
  • Automatic calibration before each measurement
  • Measurements are carried out at intervals of 1 millisecond and cover a high dynamic
  • Measurement under dynamic pressure of the liquid up to 3 mbar
  • Modular structured supplies und special equipment
  • Mobile use of the measurement system (suitcase transport)
  • Delivery of the measurement cell with certificate
  • Determination of the paper characteristics for processing: absorbancy, capillarity and e-modulus
  • Combinable with the dynamic expansion module (emco DDPM)
  • Combinable with the heating module

Applications

  • Quality assurance
  • Research and development
  • Optimization of recipes, processes and technologies
  • Investigation of troubles and warranty claims
  • Evaluation of reference offers and substitution
  • Convincing quality proof

emco DPM application cases

  • Examination of paper structures by means of water penetration of front and back side
  • Detection of surface and internal sizing as well as starch
  • Analysis of coated papers and coating base papers with various liquids
  • Analysis and detection of the dynamic of the capillarity of paper
  • Analysis of the wetting phase with various liquids, with correlations to printability, mottling, blistering, lacquering, penetration from printing colours, moisturisers, InkJet colours etc.
  • Examination of decor papers and laminates, dynamics of impregnating resin absorption and simultaneous expansion
  • Newsprint: analysis of short-term hydrophobicity, absorption behaviour of printing inks and wetting agents, dynamics of expansion
  • Label papers (all preliminary and intermediate stages), analysis of printed labels, verification of embossing, lacquer penetration, detachment behaviour with caustic soda lye up to 90 °C with simultaneous expansion measurement in MD and CD
  • Examination of special papers, felts, cigarette papers, filter papers, etc.
  • Complaint processing (printing, laminating, stamping, lay-flat, fanning-out effects)
  • Carrying out job measurements, interpretation aids
  • Simultaneous measurement of ultrasonic transmission and expansion
  • Combination of ultrasound transmission and expansion
  • Absolute signal calibration (dB) always provides the reference to the statics of the paper (stiffness, E-modulus, fiber bonding, wet fixed bonding) and allows the absolute comparison between papers
