$a Multi-factor modeling of dynamics of hardwood density in the process of thermomodification $f Ruslan R. Safin ... [et al.] 215 $c Graf., obr., tab. 320 $a Lit. 330 $a The results of experiments and statistical modeling of changes in the density of hardwood over the cross section of the samples in the process of vacuum-contact heat treatment are given in the paper. The study of the layer-by-layer density of the samples was performed using a laboratory X-ray Density profile Analyzer - DPX300. In each series of experiments, the change in the density of wood samples was recorded at the different values of temperature and time of heat treatment, sample thickness and layer depth. Modeling the process by the identification method made it possible to obtain one-factor regularities, ranked according to an increase in the correlation coefficient. It was found that the main influence on the density change is exerted by such factors as processing time and temperature. Subsequent modeling made it possible to create a four-factor model of the dynamics of the density of samples during the heat treatment, which allows the prediction of the density profile of the material depending on the thickness of the material and the operating parameters of the process. The proposed model can be further used in the development of new operating parameters of the process of vacuum-conductive thermal modification of hardwoods in order to achieve a uniform degree of processing over the entire section of lumber. 463 -1
