Jazyk dok. angličtina Krajina Slovenská republika Systematika 630*832.2 534-8 537.612.2 Heslá výroba preglejok - plywood production * močovinoformaldehydové živice - urea-formaldehyde resins * nanokryštalická celulóza - nanocrystalline cellulose * ultrazvuk - ultrasound * magnetické pole - magnetic field * pulzujúce magnetické pole - pulsed magnetic field Anotácia Possibility for obtaining high strength plywood from birch veneer ( Betula pendula Ehrh . ) superior to beech ( Fagus Ehrh . ) plywood is studied. Plywood testing for ultimate split strength in adhesive layer, tensile strength and modulus of elasticity in static bending was conducted in accordance with the applicable Russian Standards . The experimental results showed that the samples of birch plywood, manufactured using processed ultrasonic adhesive, composed of hydrogel nanocrystalline cellulose and further processed with a pulsed magnetic field, have higher physical and mechanical characteristics: ultimate split strength on adhesive layer is increased up to 3.0 MPa, tensile strength under static bending – up to 118 MPa . Pressed birch plywood regarding strength in shearing on adhesive layer exc eeds beech plywood 2.5 times . Ultimate strength in static bending of pressed birch plywood increases by two times compared to standard birch plywood.
