Problems solved by technology

However, low-quality wood has defects in appearance, such as holes where knots fall, unevenness due to wood grain, etc.
Therefore, even if low-quality wood is processed into composite panels, the above-mentioned defects in appearance may remain

Embodiment 1-3

[0053] First, the trunk of the palm (oil palm) is ground and pressed to separate it into residue and sap. Then, the residue is dried to obtain a primary ground product, and the primary ground product is further ground to obtain a secondary ground product. The secondary ground product is then sieved. The sieve used has a nominal mesh opening of 500 μm according to JIS Z8801-1. The secondary ground product is then divided into a first residue which passes the sieve and a second residue which does not pass the sieve. The first residue corresponds to the palm ground product (parenchyma cells of the palm) that will be used to make the biomass composition. Juice (solids content: about 10% by weight) was used to prepare juice compounds used as intermediates. That is, first, 25 parts by mass of citric acid was added to 100 parts by mass of saccharides to obtain a mixture, which was then heated at 105° C. to obtain a solid. This solid is then crushed into a powder, thereby obtainin...

Abstract

A biomass composition containing a pulverized palm tree material and a polycarboxylic acid is supplied onto the surface of a wood board, and then the wood board is subjected to hot press molding.

Description

technical field [0001] The present disclosure relates generally to methods for making wood composite panels, and in particular to a method for making wood composite panels containing comminuted palm tree material. Background technique [0002] Patent Document 1 discloses a method for manufacturing a bed plate of a floor. The method includes applying an isocyanate-based adhesive to wood flour, dispersing the wood flour onto the surface of a composite panel, and hot pressing to form a molded layer. [0003] However, isocyanate-based adhesives are petroleum-derived adhesives. Therefore, chassis manufactured by using isocyanate-based adhesives may be a source of generation of volatile organic compounds (VOC). [0004] High quality wood is hard to come by these days, and its price is too high to be easily available. Therefore, suitable wood must be used to manufacture composite panels, even low-quality wood. However, low-quality wood has defects in appearance, such as holes w...
