Other
Experimental facilities (specialized laboratories)
- Technological laboratory for wood treatment and wood modification (equipped with lab. scale treatment plant) allows to perform full-cell, empty-cell treatment process and OHT method;
- Laboratory of flammability (equipped with charring rate chamber; modified ASTM E69 method; Mini Fire Tube (MFT); Mass Loss Calorimeter (MLC); Limited Oxygen Index (LOI) allows to determine the reaction to fire of material acc. to EuroClasses;
- Mycological laboratory (equipped with two independent breeding and inoculation chambers dedicated to Asco- or Deuteromycetres wood disfiguring fungi and Basidiomycetes wood destroying fungi). The myco-lab allows to perform wood and wood-based materials samples in exposure to various fungal species. The laboratory allows to perform tests related to the determination of wood resistance to fungi, as well as tests on the rate of decomposition of lignocellulosic materials by fungi (biodegradation). The laboratory is equipped in laminar chambers (including Biohazard NU 400E) and high-pressure autoclaves.
Research workshop equipment
- Laboratory scale treatment plant for wood treatment with preservatives and wood modification;
- Mass Loss Calorimeter (MLC) - it allows to determine the following parameters of tested material: mass loss [%] (ML), mass loss rate [g/s] (MLR), heat release rate [kW/m2] (HRR), total heat release [MJ/m2] (THR), effective heat of combustion [MJ/kg] (HOC), time to ignition [sec] (TTI), time to flameout [sec] (TTF);
- Limited Oxygen Index LOI - it allows to determine the concentration of oxygen in the mixture of gases (oxygen and nitrogen) or multicomponent gas mixtures, which is needed for combustion of the material after ignition;
- Mini fire tube (MFT) – a mini Metz pipe, equipment dedicated to perform screenings on accelerated fire tests of wood, wood-based panels or cellulose-based samples;
- SOLARBOX 1500E: an accelerated aging chamber that allows to simulate outdoor use conditions. The device allows to perform accelerated tests of exposure of lignocellulosic materials samples to external conditions.
- Laboratory freez-dryer used for archeological wood or cellulose samples;
- Apparatus for paper sheets forming acc. to the Rapid Koethen method, with automatic or manual control, and with the possibility of recovery and re-use of water. The equipment allows for the production of innovative cellulosic or lignocellulosic materials with new functional properties.
