Definitions
- the invention relates to a material with components from palm plants, a processing device for processing raw vegetable products, preferably palm plants, and a method for producing a material.
- a material can be produced from the raw products, for example plant waste.
- the trunk is freed of “dead” palm fronds in the bottom row at mostly annual intervals. After several years, the parts of the so-called swivel sleeves that remain on the trunk during maintenance are also removed.
- Processing devices for palm waste are known.
- the trunk is usually used and chopped into wood chips.
- the wood chips are pressed together with other materials to form boards. However, these are not very stable.
- the stems and / or leaves of the palm are also not used. It is therefore an object of the invention to provide a stable material and to improve a processing device of the type mentioned at the outset in such a way that large amounts of raw vegetable products, in particular stems and / or leaves of the palm, can be stabilized in a simple and inexpensive manner , new materials can be processed.
- the material comprises elongated, shredded lamellae of pallet waxes and a binder.
- the material can be a fiber composite material.
- the starting material for the palm plants comes in particular from date, coconut and / or oil palms.
- the elongated stems which are also called panicles, can be processed.
- Palm panicles in particular comprise fibers made of cellulose and hemicellulose, which is the reinforcement for the tensile and flexural strength.
- a matrix of parenchyma, predominantly lignin and other substances, is arranged between the fibers. ensures the pressure resistance.
- the raw product preferably comes from the care of the plants, so that no plant is harvested, no tree is felled and / or no plantation has to be cleared.
- the shredded lamellae or the fibers obtained from the lamellae are elongated. These are preferably not chopped.
- the elongated structure gives the material great stability.
- the length of the slats is at least 7 cm. In contrast to shorter slats, the material is therefore much more stable.
- the length of the shredded lamellae, i.e. the fibers is at least 8 cm, 9 cm, 10 cm, 15 cm, 20 cm, 25 cm, 30 cm, 40 cm, 50 cm, 60 cm, 70 cm, 80 cm, 90 cm or 100 cm.
- At least two lamellae or fibers, preferably all lamellae or fibers, of the material can in particular be oriented parallel to one another.
- At least two lamellae or fibers, preferably half each of the lamellae or fibers, of the material can be oriented at right angles to one another.
- the slats or fibers can consequently be oriented crosswise.
- the lamellae or fibers can be randomly aligned.
- the orientation of the lamellae or fibers can be selected in accordance with the requirements for the material.
- the filler of the palm tree in particular parenchyma, is separated from the lamellae or fibers, in particular suctioned off.
- the filler is loosened during defibration.
- the filler can be completely or at least partially separated, ie removed. For example, at least 50%, 70%, 80%, 90% or 95% of the filler can be removed.
- the material is at least substantially free of, e.g. densified, filler.
- the lamellae or fibers are wetted with binder, so that a homogeneous material is created.
- the swelling in thickness is approximately 74%.
- the thickness increases to 20.9 mm after 24 hours of water storage.
- the swelling in thickness is approximately 8%.
- the thickness increases to 12.9 mm after 24 h of water storage.
- the swelling in thickness is approximately 1%.
- the thickness increases to 12.1 mm after 24 h of water storage.
- the swelling in thickness is approximately 0%.
