Lignocellulosic board, process and plant for its production

Patent No. RO 115435

Product description

Our proposal deals with a flat board of broken up lignocellulosic materials, (chips, fibers, sawdust, etc.) using synthetic or natural resins, cement, plaster (with or without addition of fillers either syntetics or mineral as slag, ashes, etc) pressed perpendicular to face, with penetrant perforations perpendicular to board faces.

The flat board thickness is variable, between 8 - 40 mm as required.

The object of this new product lies in the necessity for a rigid selfsupporting board having higher thickness and lesser weight, phono - and thermoinsulating properties.

Application:

A) Boards made exclusively with lignocellulosic materials glued with natural or syntetic resins, with or without fillers like slag ashes:
  • wood prefab. houses (walls, floors, ceilings, doors);
  • indoor partition;
  • joinery.

    B) Boards made with lignocellulosic materials and mineral binders (cement, plaster, etc) with or without slag, ashes:
  • housing (walls, floors, ceilings);
  • indoor partition;

    The product can be veneered, paper laminated, painted, etc.
  • The proposed size: 1220 x 2440 mm;
  • Thickness: 8 - 40;
  • Diameter of perforation: 40 mm
  • Raster: 80 x 80 mm
  • The rate of perforation in board volume: 15 - 20%.

    Board density varies with wood species, ratio of hollows, glue, etc. Density values ranges between 350 - 750 Kg/cum.

    In case of boards made with mineral binders (cement, plaster) the density diminuishes proportionally with hollows volume.

    This board has been presented at the Inventics Saloons from Bruxelles 2000 (EUREKA) and Geneve 2001 being highly appreciated by specialists and receiving the silver medal.

    Also, after the product presentation within the EPF Annual General Meeting from 20 - 21 June 2001, at Edinbourgh, it appeared in an issue of the prestigious reviews DATALIGNUM No. 171 from September 2001 and HOLZ UND KUNSTSTOFFVERARBEITUNG [HK] No. 11 / 01 from 2001.
