Ultrasonic Tester for the Determination of Paper/Board and Liquid Properties via the Wetting and Absorption Behavior specific of high viscous liquids, as for example adhesives, printing ink, coating colors
prediction of converting properties
Offset: strike-in of fountain solutions, oils or inks
Gravure: missing dots potential in LWC papers
Flexo: wetting and penetration behavior of flexo inks
Ink jet: wetting and penetration behavior of ink jet inks glueability
Surface sizing, surface porosity
Film generation of dispersion adhesives
Dynamic Water Retention of coating colors
No cleaning effort after measurement
Small amount of testing liquid required: 3.5 ml
Chemical suppliers (adhesives, printing ink)
Producers of paper/board
The test liquid is applied on the horizontal area of a measuring cell, which includes the ultrasound transmitter, possibly together with a protection foil. The paper sample is applied by means of double-sided adhesive tape at the measuring head, which contains the ultrasound receiver.
For a measurement the measuring head is lowered together with the paper sample until it is contacted with the test liquid.
