Abstract
Przedmiotem zgłoszenia jest sposób wytwarzania płyt osłonowych na bazie włókien lignocelulozowych spajanych środkami spożywczymi, w którym włókna drzewne o wilgotności do 50%, korzystnie o wilgotności od 2% - 30% pokrywa się roztworem mąki lub mąką, formuje się z nich kobierzec o założonej gęstości, korzystnie z przedziału od 100 do 250 kg/m3, korzystnie o gęstości 130 -180 kg/m3, po czym prasuje się je między gorącymi płytami grzejnymi o temp. 120°C — 210°C, korzystnie 150°C — 180°C, grubość uzyskanych płyt wynosi od 15 mm — 35 mm, korzystnie o grubości w przedziale 20 mm — 25 mm. w czasie od 12 do 48 s na mm grubości płyty, po czym po prasowaniu płyty poddaje się dosuszeniu do wilgotności poniżej 10%.The subject of the application is a method of producing casing panels based on lignocellulosic fibers bonded with foodstuffs, in which wood fibers with a moisture content of up to 50%, preferably with a moisture content of 2% - 30%, are covered with a flour solution or flour, and a carpet of a given density is formed from them, preferably in the range from 100 to 250 kg / m3, preferably with a density of 130-180 kg / m3, after which they are pressed between hot plates at a temperature of 120 ° C - 210 ° C, preferably 150 ° C - 180 ° C, the thickness of the plates obtained ranges from 15 mm to 35 mm, preferably with a thickness in the range 20 mm to 25 mm. for 12 to 48 seconds per mm of board thickness, then, after pressing, the boards are dried to a moisture content below 10%.
