Description
40000 кг/см 4x800x998x360000x0,25 - 18,7 см. 48x40000x8000 При этом длина капилл ров в раст нутой зоне образца будет приблизительно равна 2Х/ 3002-f 18, см. Так как предел прочности вдоль волокон в раст нутой и сжатой зонах образца равен соответственно 998 и 413 кг/см, то при удлинении капилл ров образца в раст нутой зоне на /у -601 см-600 см-1 см произойдет сокращение капилл ров в сжатой зоне в 998 кг/см ;413 кг/см2 ::2,4 раза, т. е. смХ2,4 2,4 см. При вращении прогнутого образца происходит изменение длины капилл ров на величину , равную /у-|-;с 1 см-f 2,4 см 3,4 см. Форм у л а изобретен и Способ пропитки древесины, включающий выдержку ее в ванне с пропитывающим составом , отличающийс тем, что, с целью обеспечени интенсификации, перед выдерлской в ванне древесину укладывают на катковые опоры, установленные в ванне, прогибают промежуточной катковой опорой и вращают вокруг продольной оси с угловой скоростью 1-20 рад/сек в течение 2-20 мин, причем прогиб древесины определ ют по формуле: f - i W- -l-K 48-E-J е f - прогиб сортимента древесины, см; W-момент сопротивлени сечени данного сортимента, кг/см ; а -предел прочности при раст жении вдоль волокон данной породы древесины , кг/см ; / - длина сортимента древесины, см; Е - модуль упругости древесины поперек волокон, кг/см ; / - момент инерции сечени данного сортимента древесины, кг/см ; ,25 и 0,33 - коэффициент выносливости при изгибе знакопеременным нагрузкам соответственно дл хвойиых и листвениых пород древесины.

As the tensile strength along the fibers in the stretched and compressed zones of the sample is 998 and 413 kg / cm, respectively, when the sample capillaries are elongated in the stretched zone by / at -601 cm-600 cm-1 cm, the capillaries in the compressed zone will decrease to 998 kg / cm; 413 kg / cm2 :: 2 , 4 times, i.e. cmX2.4 2.4 cm. When the bent sample is rotated, the length of the capillaries changes by an amount equal to / у - | -; from 1 cm-f 2.4 cm 3.4 cm. Forms invented and spe about wood impregnation, which includes exposing it in a bath with an impregnating composition, characterized in that, in order to provide intensification, before the wood in the bath, the wood is placed on roller supports installed in the bath, bend the intermediate roller support and rotate around the longitudinal axis with an angular velocity of 1 -20 rad / sec for 2-20 minutes, and the deflection of wood is determined by the formula: f - i W- -lK 48-EJ e f - deflection of the assortment of wood, cm; W-moment of resistance of the cross section of this assortment, kg / cm; a is the tensile strength along the fibers of a given wood species, kg / cm; / - the length of the range of wood, cm; E is the modulus of elasticity of wood across the fibers, kg / cm; / - moment of inertia of the cross section of this assortment of wood, kg / cm; , 25, and 0.33 are the coefficient of endurance in bending with alternating loads, respectively, for coniferous and foliage species of wood.
