Analysis (Pulp and paper properties)

Pulp analyses

Pulp analyses include SR, CSF, WRV, FSP, pore size distribution of fiber cell wall, water fractions in fibers.

Drainage and Retention: The Dynamic Drainage Analyzer (DDA) with four dosage units measures drainage, but can simultaneously give retention, wet sheet permeability and the sheet dry solids content of paper pulp, under the conditions simulating paper making. In addition, it can be used to solve drainage problems in other systems.

Paper testing

Paper testing: Testing is performed in standard climate (50 % RH, 23 °C). There are also two climatic test cabinets for controlling temperature and humidity of samples. Following paper properties can be tested:

Mechanical properties

Tensile strength, index, TEA

Tear strength, -index

Burst strength

Compression strength, -index   

Bending resistance, stiffness       

Bonding strength            

Fracture toughness   

Tensile stiffness index, -orientation             

ECT, RCT, CCT                                                                    

Optical properties

Spectrofotometric measurements

Gloss

Surface, porous and absorption properties

Roughness/smoothness (Bendtsen, PPS, Gurley)

Air permeability (Bendtsen, Gurley)

Gas permeability profiler (Ambertec)
