Method and apparatus for producing a board
11518061 · 2022-12-06 · ·

A method of producing a board for production of panels is provided comprising: providing particulate material comprising or consisting of particulate wooden material, producing glued particulate material by applying an adhesive to the particulate material, forming a spreading material mat by homogeneously spreading the glued particulate material onto a conveyor on which the spread glued particulate material is conveyed in a conveying direction, and producing a board by pressing the spreading material mat. A reinforcement material is applied to the spread glued particulate material parallel to the conveying direction during forming the spreading material mat and/or after forming the spreading material mat before any pressing of the spreading material mat such that the spreading material mat has at least one longitudinal reinforcement zone containing the reinforcement material. Boards can be obtained from which panels can be produced which have reinforced longitudinal and/or transversal edges.

Binder materials

A method for producing a shaped article comprising: a) providing a binder, which has been produced by a process of: (i) mixing (A) fungi or glucan and (B) starch with an alkaline agent to form an alkaline composition; and mixing the alkaline composition with an acidic agent to form the binder; or (ii) mixing (A) fungi or glucan and (B) starch with an acidic agent to form an acidic composition; and mixing the acidic composition with an alkaline agent to form the binder; (b) forming a binder composition by mixing the binder with filler material; (c) shaping the binder composition into a three-dimensional shape; and (d) curing the binder composition to form a shaped article having said three-dimensional shape, wherein steps c) and d) can be carried out simultaneously or separately, and wherein during one or both of steps c) and d) pressure is applied to the binder composition.

Construction panel having improved fixing strength

A plasterboard comprising a gypsum matrix having wood particles embedded therein in an amount of at least 2 wt % relative to the gypsum, the gypsum matrix further comprising glass fibres in an amount of at least 1 wt % relative to the gypsum.

Composition of a composite material for containers, method of the preparation thereof and its use. The composition comprises a continuous matrix of a thermoplastic polymer having a melting point higher than 110° C. and, distributed within the matrix, non-fibrillated wood particles having a sieved size greater than 1.0 mm. The weight ratio of thermoplastic polymer to wood particles being 45:55 to 80:20. Material further contains 0.1 to 10% by weight, calculated from the total weight of the thermoplastic polymer and the wood particles, of a slate-like mineral pigment. The material is particularly suitable for containers of cosmetic products, for foodstuff and for beverages.

A method for producing a composite material comprises the following steps: comminuting wood elements into wood fragments; crushing the wood fragments; mixing the wood fragments with an adhesive agent and/or a bonding agent; and pressing the mixture of wood fragments and the adhesive agent and/or bonding agent.

PROCESS FOR THE PRODUCTION OF PARTICLE BOARD OR WOOD FIBER BOARD

A process for the production of particle board, MDF board or HDF board includes the step of recycling particle board material, MDF and/or HDF board material in which recycled chips and/or recycled wood fibers are produced. The process includes the step in which the particle board material, the MDF and/or HDF board material is wetted, heated and pressurized, such that this material is kept under pressure and at an elevated temperature for a certain time. The process involves the step of supplying the recycled chips and/or the recycled wood fibers as base material in a production process of particle board, MDF board or HDF board.
