Ermittlung der Sorptionsisothermen von Holzwerkstoffen bei verschiedenen Temperaturen mit einem neuen Meßverfahren

To determine sorptional isotherms of wood based materials at various temperatures, a new computer aided measuring system has been developed. By this method, the equilibrium moisture contents at various temperatures are reached within 8 hours already. Here, instead of adaptation of specimen's moisture content to constant air humidities, the adaptation of air humidity to the specimen's constant moisture content is measured. The specimens whose moisture contents are gravimetrically determined are placed in air-tight containers, with climate recorded by sensors for temperature and moisture. The containers themselves are situated in climate chambers, there measurements are carried out at temperatures between ?20°C and 60°C.
