Definitions
- the subject of an invention is a production method of pulp for producing composite boards from lignocellulosic fibres derived from biomass, as well as a pulp board produced according to the method.
- Boards made from pulp are applied in timber industries, i.e. for producing furniture, floor panels, decorative strips, as well as in the construction sector as insulating materials, both thermal and acoustic.
- materials Residues
- a chipboard is produced through joining relatively large fragments of wood with resin, whereas a fibreboard is produced through connecting separated lignocellulosic fibres with resin.
- Blades are cut, soaked in water and treated with steam under high pressure in order to soften the stems. Blades prepared in such a way may be mixed in any proportions with other fibre materials, such as fibres derived from wood, and used in wet, dry, and wet-dry wood-like board production.
- US 6,596,209 document presents a production of chipboards from materials of non-woodworking origin, where resources preferred are selected according to high cellulose and hemicellulose level and low silica level.
- the processing method is characterized by a short time of cleaning and low pressure of steam softening the blades.
- fibreboards are made from fibres of deciduous or coniferous trees, joined together with waxes or resins in high temperature and increased pressure. Boards produced in such a way are characterized by high homogeneity and dimensional stability, constituting a valued building material. Production parameters have an influence on the end product parameters, such as durability and density, which allows to obtain boards for various purposes. Low density boards are suitable for acoustic insulation, whereas high density boards are used in woodwork.
- Properties of fibreboards may exceed parameters of solid wood, and the possibility of using various additives allows to produce boards with special parameters, such as fire resistance and moisture resistance.
- Using antraquinone known from the paper production process positively influences water resistance of the boards.
- US 1,627,103 document reveals a board production processed based on fibres from sugarcane residue boiled in calcium hydroxide solution.
- insecticides may be added to fibres treated in such a way in order to produce an insect resistant board.
- cement with sodium silicate it is possible to add cement with sodium silicate.
- a product obtained in such a way may be cut, sawn and processed similarly to ordinary wood.
- WO 2006076814 patent document reveals urea, melamine, formaldehyde, phenolic and isocyanate resins as fillers joining lignocellulosic fibres in a board.
- WO2006076814 document reveals potential sources of fibres for producing fibreboards. Fibres suitable for fibreboard production may be derived from widely cultivated plants, such as hemp, sugarcane, bamboo, banana tree stems and leaves, coir, coconut, corn, cotton, flax, papyrus, rice, wheat, rye, grass, straw and oats. Using such materials allows to limit the amount of agricultural waste and save valuable resources such as wood.
- EP 0644861 document reveals a method of cellulosic fibre mass production from fragmented waste paper and wood waste, which is formed into boards after mechanical treatment.
- EP 1412566 reveals a method of producing nonwoven fabric including the use of cellulosic fibres from waste paper processing that are bound with the help of thermoplastic elastomer fibres.
- waxes such as beeswax, paraffin, lanolin and jojoba oil
- plastics such as polyethylene and polypropylene
- the essence of the invention is the method of pulp production for producing boards; cereal straw is fragmented to the form of blades with a length from 10 to 50 mm, which are then subjected to hydrothermal treatment. Mass obtained is injected with the help of a feeding machine between the milling plates of the defibering unit until it is defibered, and then pressed with the help of a screw press until obtaining absolute humidity below 50%. Mass obtained is loosened into the pulp form and dried.
- the method is characterized in that the cut cereal straw blades are subjected to hydrothermal treatment with water mixture at temperature below 50°C, where hydrothermal treatment does not last longer than 1 minute.
- a method according to the invention is characterized in that a hydrothermal treatment takes place in water and lye solution. Such a solution allows straw maceration and results in reducing energy consumption of the defibering process.
- a method according to the invention is characterized in that a hydrothermal treatment takes place while evenly feeding mass of concentration between 8 and 10% between round knives.
- a method according to the invention is characterized in that cellulosic resources, especially waste paper fibres in a proportion up to 50% by weight of cellulosic fibres, are also added to cereal straw blades.
- cellulosic resources especially waste paper fibres in a proportion up to 50% by weight of cellulosic fibres
- Such a solution conveniently influences the cohesion of mass, since cellulosic fibre is finer than straw fibre.
- the method according to the invention is characterized in that cereal straw is fragmented to the form of blades with a length from 10 to 50 mm, conveniently to 30 mm.
- the lengths of fibres according to the invention conveniently influence physical-mechanical properties of products obtained.
- An essence of the invention is also a pulp board, characterized in that it contains pulp produced according to the method according to the invention and the binder.
- a board according to the invention is characterized in that it also contains an additive of non-defibered particles of lignocellulosic material, amounting from 1% to 50% by weight. Thanks to introducing defibered particles, it is possible to shape physical-mechanical properties of a ready product.
- a board according to the invention is characterized in that it also contains an additive of plastic fibres, especially an additive of aramid fibres. Thanks to introducing non-defibered particles, it is possible to shape physical-mechanical properties of a ready product.
- a board according to the invention is characterized in that it also contains an additive of cellulosic acetate. Thanks to the introduction of cellulosic acetate, an improvement of hydrophobic properties and cohesion of the boards has been obtained.
- a board according to the invention is characterized in that its binder is melamine-urea-formaldehyde resin, isocyanate adhesive or mixture of both, conveniently in the amount relative to dry mass of the product between 5% and 15%, more conveniently between 8% and 12%.
- a binder according to the invention in the proportions indicated above allows to obtain required usage properties (including especially durability) of boards.
- the advantage of the invention is using agricultural waste for producing dry-formed boards.
- Boards of low density may be used as insulation material and as external room insulation, securing i.e. against changes caused by weather conditions. Specific properties of the product allow to protect buildings against overheating in summer and overcooling in winter. Also, the building material of the board is characterized by high capacity of noise suppression, thanks to which the transfer of high pitched sounds from external sources is significantly reduced.
- the product of medium density constitutes an alternative to MDF, HDF and OSB boards used in the furniture sector, competitive both in quality and price.
- a low level of energy is necessary for obtaining a resource, which results in lower production costs and a lower price of an end product.
- An advantage of the method of board production according to the invention is using easily accessible and rapidly renewable materials constituting agricultural waste for producing wood-like boards in the process of resource treatment in lowered temperature. Mass obtained in such a way is characterized by a specific amount of fats and other hydrophobic substances. Mass obtained in such a way may be stored in a silo for further use or directly mixed with resin and additives, and fed to the board production press. Thanks to natural occurrence of hydrophobic substances in straw, such a board is characterized by an increased moisture resistance.
- Fig. 1 presents the process of pulp production and its further treatment in order to produce a wood-like board.
- resources are cleaned in order to remove small stones and other non-organic materials.
- cereal straw with additives is fragmented until obtaining fibres with a length from 30 to 50 m.
- Lignocellulosic fibres cut in such a way are loosened hydrothermally in temperature of 50°C.
- Water and lye solution is fed into the zone between the milling plates.
- the resource is loosed mechanically through injecting mass with the help of a feeding machine between the milling plates zone of an appropriate defibering unit, while water is fed simultaneously to the milling zone in order to remove excess heat released in the defibering process.
- mass is pressed with the help of a screw press until obtaining humidity below 50%, and loosened with a mixer and dried into the dry fibre mixture form. Mass obtained in such a way may be stored in a silo for further use or directly mixed with resin and additives, and fed to the composite board production press.
- biomass used may be derived from agricultural waste, especially straw.
- Pulp may contain additives in the form of fibres from fragmented waste paper. Straw is fragmented to the form of blades with a length from 10 to 50 mm, which are then subjected conveniently to intense and short hydrothermal treatment with using alkaline solution at temperature lower than 50°C together with an additive of other lignocellulosic resources.
- the resource is loosed mechanically through injecting mass with the help of a feeding machine between the milling plates zone of an appropriate defibering unit, and pressed with the help of a screw press until obtaining humidity below 50%. Next, mass obtained is loosened into the pulp form and dried.
- a hydrothermal treatment takes place water and lye solution.
- a hydrothermal treatment takes place while evenly feeding mass of concentration between 8 and 10% between round knives.
- a pulp board may contain an additive of non-defibered particles of lignocellulosic material, amounting from 1% to 50% by weight.
- a pulp board may also contain an additive of plastic fibres, especially an additive of aramid fibres.
- a pulp board may contain an additive of cellulosic acetate.
- a board made from pulp of low density with using 75% of lignocellulosic fibre and 25% of cellulosic fibre from waste paper has been obtained; the mixture was subjected to treatment method according to the invention, especially with using hydrothermal treatment with water mixture at 50°C.
- An appropriate time of pressing allows to obtain a board of density from 120 to 300 kg/m 3 ; especially convenient insulation properties are obtained with density from 170 to 190 kg/m 3 .
- a board made from pulp of high density with using 70% of lignocellulosic fibre and 30% of cellulosic fibre from waste paper has been obtained; the mixture was subjected to treatment method according to the invention, especially with using hydrothermal treatment with water mixture at temperature of 45°C.
- Melamine-urea-formaldehyde resin (MUF) amounting to 12% was used as a binder for board production.
- An appropriate time of pressing allows to obtain a board of density from 700 to 900 kg/m 3 ; especially convenient mechanical properties are obtained with density from 700 to 750 kg/m 3 .
