TECHNISCHES UMFELDTECHNICAL ENVIRONMENT
[01] Die vorliegende Offenbarung betrifft das Gebiet der Prävention und Kontrolle von Formaldehydverschmutzung bei Platten auf Holzbasis und insbesondere ein Ver- fahren zur Fertigung einer aldehydfreien phenolfreien Platte auf Holzbasis durch Elimi- nieren von Formaldehyd mit einem Photokatalysator/Wellenkatalysator.[01] The present disclosure relates to the field of prevention and control of formaldehyde pollution in wood-based boards, and more particularly to a method of manufacturing an aldehyde-free phenol-free wood-based board by eliminating formaldehyde with a photocatalyst/wave catalyst.
TECHNISCHER HINTERGRUNDTECHNICAL BACKGROUND
[02] Eine große Menge an Klebstoff mit hohem Formaldehydgehalt wird in den[02] A large amount of adhesive with high formaldehyde content is in the
Fertigungsverfahren für Platten auf Holzbasis verwendet. Da Formaldehyd der mensch- lichen Gesundheit schaden kann, steht im Fokus der Bedenken der Verbraucher, wie dieManufacturing process used for wood-based panels. Because formaldehyde can be harmful to human health, consumer concerns are focused on how the
Produktion von Formaldehyd bei Platten auf Holzbasis vermieden werden kann. Aktiv- kohle ist ein Formaldehydeliminierungsmodus, der üblicherweise im Wohnbereich ver- wendet wird und preiswert ist. Bei Aktivkohle kann jedoch binnen kurzer Zeit eine Ad- sorptionssättigung eintreten, und gefährliche Substanzen können wieder zurück in dieProduction of formaldehyde can be avoided with wood-based panels. Activated carbon is a formaldehyde elimination mode that is commonly used in residential settings and is inexpensive. With activated carbon, however, adsorption saturation can occur within a short time and dangerous substances can return to the
Luft abgegeben werden, wenn in der Zeit nach der Sättigung kein Ersatz durch neueAir will be released if in the period after saturation no replacement with new ones

Der wichtigste Punkt bei der Verwendung der Aktivkohle liegt zu- dem darin, dass eine groBe Menge an Aktivkohle verwendet wird, so dass ein Mindest- effekt erreicht werden kann, wenn lediglich Formaldehyd mit Aktivkohle adsorbiert wird, und dass im Unterschied dazu durch falsche Anwendung Schaden entstehen kann.Charcoal bag done. In addition, the most important point in using the activated carbon is that a large amount of activated carbon is used, so that a minimum effect can be obtained only by adsorbing formaldehyde with activated carbon, and on the contrary, there is harm from misuse can arise.
[03] Die Platte auf Holzbasis weist auf drei Hauptwegen eine Formaldehydver- schmutzung auf, wobei der erste in freiem Formaldehyd liegt, das nicht-umgesetzt in der Platte auf Holzbasis vorliegt, der zweite Formaldehyd ist, das durch Hydrolyse von[03] The wood-based board exhibits formaldehyde pollution in three main ways, the first being in free formaldehyde present unreacted in the wood-based board, the second being formaldehyde produced by hydrolysis of
Klebstoff bei Gebrauch der Platte auf Holzbasis produziert wird, und der dritte Formal- dehyd ist, das durch Holzalterung bei Gebrauch der Platte auf Holzbasis produziert wird. Die Projektgruppe hat gefunden, dass das freie Formaldehyd, welches nicht-umgesetzt in der Platte auf Holzbasis vorliegt, die Hauptursache für überschüssi- DE20E1/5918 ges Formaldehyd in Platten auf Holzbasis ist, was 95 % oder mehr der Formaldehydver- schmutzung stellt. Formaldehyd und VOCs kônnen, wenn sie sich unter Einfluss vonAdhesive is produced using the wood-based board, and the third is formaldehyde, which is produced by wood aging using the wood-based board. The project group has found that the free formaldehyde that is unreacted in the wood-based board is the main cause of excess formaldehyde in wood-based boards, which accounts for 95% or more of the formaldehyde pollution. Formaldehyde and VOCs can occur when under the influence of
