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)
Oil and water absorption (Cobb, Cobb-Unger)
Beta formation (Ambertec)
