Abstract: | The present researches are directed on studying of influence of separate soft hardwood and their mixes on physicomechanical indicators of received wood-fiber plates. Properties of the basic component of a composition of the plates, defining quality of finished goods – a defibrators wood pulp are investigated. Experiments are spent with the cores forest formative soft hardwood of Byelorussia – a birch, an aspen, an alder black. It is established, that use of this wood in an initial condition at reception of wood-fiber plates is technically inexpedient, that is connected with their low durability. Chemical processing wood щепыbefore defibrators milling a carbamide and lye from magnesium-bisulfitnoj of cooking of cellulose with expenses of 3% to а. d. s., allows to raise technical properties of a wood pulp and, hence, and durability of plates on size to 30%. Results of industrial tests have confirmed laboratory researches and have shown, that use of such reception in technology of wood-fiber plates allows to receive plates from wood of deciduous breeds demanded by the quality standard. |
