EST 12 - Surface and Sizing Tester
Ultrasonic Tester for the Determination of Paper/ Board Properties via the Wetting and Absorption Behavior of Liquid
QUICK TESTER FOR SIMPLE, EFFICIENT AND ACCURATE SURFACE TESTING OF PAPER AND BOARD FOR:
Surface sizing/internal sizing
Surface porosity
Coating quality / binder filming
FOR PREDICTION OF CONVERTING PROPERTIES:
Printability
Glueability
Coating base paper quality
ADVANTAGES:
Easy handling
Automatic calculation of parameters
Portable
Partly substitution of Cobb-Tester
Useable with a PC
MAIN USER:
Paper/ board producer
chemical suppliers
Paper/ board converter
MEASURING RESULTS:
Intensity-time-diagram (with PC)
Automatic calculated values
OPERATION:
comparable to PDA.C 02 Module Standard
FIELD OF APPLICATION:
Quality testing for internal- and surface-sized, coated respectively uncoated paper and board
Grammages up to 600 g/m2
MEASURING RESULT:
Automatically calculated quality parameters MAX and t(95)/t(99) with excellent correlation to the results of the Bristow Wheel Test and the Contact Angle Test, Hercules Sizing Test HST (no correlation to HST possible, if paper sample contains CaCO3-filter!)
ADVANTAGES:
Portable low cost unit
Ideal for quality control directly in production plants, for trial support by chemical application engineers and for troubleshooting
