Paper and Board Analysis Services

Laboratory Analysis Services for Paper and Board

Tapio Measurement Technologies offers paper analysis laboratory services. Measurement in precision laboratory analyzers at a slow track speed enables a high resolution and high accuracy. The results can be used for troubleshooting, headbox operation analysis, guerantee verification as well as the verification of QCS systems. 

Paper and Board Analyzer systems

Tapio Measurement Technologies offers paper machine analyzers and measurement equipment suitable for the precision measurement of almost all paper and board grades as well as other suitable rolled products.

We offer two types of analyzer devices: 
• Tapio Analyzer, a system for analysis of both CD and long MD samples
• Tapio Profiler, a smaller unit for analysis of CD samples and short MD samples

Both analyzers support the same sensors.

Available sensors

Basis Weight Sensor BW

Tapio basis weight sensor

• Various models: Pm-147 for paper grades, Kr-85 for all grades
• Semiconductor detectors

• Verification and calibration of online measurements
• Ideal for paper machine troubleshooting

Ash Sensor

Tapio Ash Sensor

 Fe55 source with seminconductor detector
• 2 selectable apertures, 5 mm and 10 mm
• Coated, filled grades
• Filler content measurement
• Retention problems
• Coat weight, coating weight variation, coater optimization etc.

Transmission

Tapio Transmission sensor

• 1 mm aperture
• All grades, wavelength selectable white / red / IR
• Press section variations, moisture and temperature related variations 
• Optical formation and flock size analysis
• Importand when calender, press section and wet end effects must be separated from each other

Remission / Brightness

Tapio Remission sensor

 0.3 mm aperture
• Brightness variation of paper
• All grades
• Correlates with coating variations
• Calender blackening studies
• White top board (see-through variation)

Moisture

Tapio Moisture Sensor

• Near-infrared reflection
• 3 – 20 % moisture content
• Spot diameter 13 mm

Porosity

Tapio Porosity Sensor

 Air permeability measurement
• Permeability variations
• According to laboratory standards (Bendtsen, Gurley, Bekk, etc.)

Calculated properties

The following properties are calculated from a combination of other measurements:

• Density
• Opacity
• Bone-dry basis weight
• Relative ash (%)

Tapio Analyzers can pinpoint the source of variation

Tapio Analysis can be used to determine which machine elements are causing variations in the end product:
• Stock approach, screens, fan pumps, etc.
• CD Basis Weight Actuators, Jet to Wire Ration, Formation, Wire Uniformity & Marking
• Press vibration problems, Nip pressure uniformity, Felt condition

• CD Moisture and Caliper profiles
• Actuators
• Verification and calibration of QCS and other online measurement systems

• Coaters, Size Presses
• IR Dryers
• CR Coat weight control

• Calendering uniformity
• Calender blackening
• Calender bearing vibration
