A manufacturing method of a panel member (1) in accordance with the present invention includes: a processing step of processing a veneer sheet (2), which is obtained by processing wood into a sheet, into a predetermined desired shape; and a resin molding step of setting the veneer sheet (2), which has been processed in the processing step, on a mold M1 and pouring a transmissive resin onto a front surface side of the veneer sheet (2) to mold a base material part (3). The base material part (3) is molded such that the plate thickness thereof gradually changes.

This invention relates to a process for modifying wood. The process comprises treating the wood with an impregnating solution comprising an alkali metal (or alkaline earth metal) silicate, under conditions sufficient to impregnate the wood with one or more of the components of the impregnating solution. The process can comprise an optional second impregnation with a second impregnating solution. The process also comprises adding gaseous carbon dioxide to the treated wood, in the absence or presence of water, under pressure ranging from about 2 to about 12 bars, thereby lowering the pH of the treated wood to about 11 or below, to stabilize and/or fix the components of the impregnating solution in the wood. The process is green, non-toxic, and the resulting modified wood or wood product can be used across all primary construction and infrastructure applications.

A continuous wood modification by heat process, that comprises: stacking wooden boards on a trolley at intervals; exerting pressure on said wooden boards; transferring said wooden boards to a heating kiln, pre-heated by microwave and hot air circulation, that has a water vapor flow of 2-5 meter3/hour, a temperature range of 60-100° C., and a humidity range of 50%-100%; transferring said wooden boards to a shallow drying kiln, pre-heated by microwave and hot air circulation, that has a drying temperature of 100-120° C.; transferring said wooden boards to a deep drying kiln, pre-heated by microwave and hot air circulation, that has a drying temperature of 120-120° C., an oxygen content range of 1-10%, and a water vapor flow rate of 1-10 m3/hour; transferring said wooden boards to a carbonization kiln, pre-heated by microwave and hot air circulation, that has a temperature range of 120-180° C., an oxygen content range of 1%-5%; transferring said wooden boards to a slow cooling kiln, that has a temperature range of 120-130° C., and an oxygen content range of 1%-10%; transferring said wooden boards to a fast cooling kiln, that has a temperature range of 90-100° C.; transferring said wooden boards to a rewetting kiln, that has a humidity range of 50%-100%; providing water vapor to said rewetting kiln; while being in said rewetting kiln, and when a temperature range of said wooden boards is 40-60° C., and a moisture content of said wooden boards is 6%-10%, transferring said wooden boards out of said rewetting kiln; wherein each of said heating kiln, said shallow drying kiln, said deep drying kiln, said carbonization kiln, said slow cooling kiln, said fast cooling kiln, and said rewetting kiln comprises a fan, a partition board, a shunt hood, and an exhaust port; wherein said partition board divides an interior of each of said heating kiln, said shallow drying kiln, said deep drying kiln, said carbonization kiln, said slow cooling kiln, said fast cooling kiln, and said rewetting kiln into an upper chamber and a lower chamber; wherein said shunt hood is disposed in said upper chamber; wherein said fan, said shunt hood, and said lower chamber are connected and form a air channel; wherein said lower chamber comprises a shunt plate, disposed along left and right walls of a kiln; wherein said shunting plate comprises a plurality of sieve holes that are disposed gradually dense from top to bottom; wherein one end of said shunt plate is connected with said partition board and the other end is connected with the bottom of a kiln.

A method of heat treating a wood board comprises: passing a wood board from an input end to a discharge end of a conveyor; and heating the board with radiant heat as it is passes along the conveyor, the heating can be such as to provide significant charring of the wood. The wood board is then brushed with at least one rotating brush. An apparatus, for carrying out the method, has a conveyor for conveying a wood board having an input end and a discharge end. A radiant heater is located above the conveyor for heating the wood board, and a rotating brush is mounted for rotation above the conveyor, for brushing the wood board after heating.

Different aspects of the invention refer to a disinfection apparatus, and corresponding method, for wood barrel disinfection using microwave shock pulse, MwSP, technology for the complete elimination of microbial populations. This is accomplished by a system which ensures deep and complete disinfection, however such that the temperature is maintained below material degradation level. Complete disinfection is achieved due to effectiveness up to the deepest layers. The wooden barrel material is however preserved, due to the non-harmful nature of the dosage regime programmed into the radio frequency emission.

A process for treating lignocellulosic pieces with a water-soluble lignocellulosic material preservative. The process comprises the step of contacting the lignocellulosic pieces with a water-based preservative solution having a contact temperature between about 70 C. and about 95 C., the water-based preservative solution containing the water-soluble lignocellulosic material preservative in a concentration above about 25% wt. A lignocellulosic treatment apparatus for treating lignocellulosic pieces is also provided.

The disclosure relates to a method for the production of wood fiberboards such as MDF boards.

Methods and systems for recovering terpenes and controlling the composition of terpenes collected from wood drying processes are provided. In particular, a sorbent having adsorbed materials, including terpenes, from a wood drying process can be desorbed in a desorber, resulting in a gaseous stream containing terpenes, which can be condensed and collected from the gaseous stream. The conditions of desorption can be controlled to ensure a desirable amount of alpha-pinene and beta-pinene relative to other terpenes, such as dipentene and camphene, in the collected terpenes.
