摘要
On the base of experimental observations of mass loss rate in dependence of temperature in isothermal condition in circulating air atmosphere was determined the activation energy of lignocellulosic materials degradation without and with retardants. Experiment was performed in an electrically heated hot-air furnace according to ISO 871 standard (Setchkin furnace) in conjunction with precision scales. Degradation of lignocellulosic materials was performed at various temperatures and various air-flow speeds. Pure cellulose as a model compound was impregnated by water solution of KHCO3 and (NH4)(2)HPO4.
