Abstract
The present invention relates to a method for producing an engineered wood, comprising the steps of: (a) breaking down a veneer to increase its porosity; (b) impregnating the veneer from step (a) with an adhesive material; (c) drying the veneer from step (b) to a predetermined moisture content level; (d) arranging a plurality of the veneers from step (c) in a mould; and (e) pressing the plurality of the veneers in the mould. The engineered wood has an appearance of natural timber, and is able to withstand extreme weather conditions and have minimum warping, rotting and termite infestation.
Claims32
A method of producing an engineered wood, comprising the steps of:
- (a) breaking down a veneer to increase its porosity;
- (b) impregnating the veneer from step (a) with an adhesive material;
- (c) drying the veneer from step (b) to a predetermined moisture content level;
- (d) arranging a plurality of the veneers from step (c) in a mould;
- and
- (e) pressing the plurality of the veneers in the mould.
The method according to any of the preceding claims, the method further comprises arranging the plurality of veneers to simulate a natural wood grain pattern.
The method according to any of the preceding claims, the method further comprises selecting a mould with a natural wood grain pattern.
The method according to any of the preceding claims, further comprises placing the mould holding the plurality of veneers into a container after step (d) and prior to step (e), wherein the sidewall of the container has a plurality of holes configured to receive at least one rod or pin.
The method according to any of the preceding claims, wherein step (a) comprises breaking down the veneer with at least one studded wheel.
The method according to any of the preceding claims, wherein the method further comprises rotary peeling the veneer from a wood prior to step (a).
The method according to any of the preceding claims, further comprises drying the veneer to a moisture content level of about 5% to about 18% prior to step (a).
The method according to any of the preceding claims, wherein the method comprises trimming the veneer to a width of about 150 mm to about 300 mm prior to step (a).
The method according to any of the preceding claims, wherein step (b) comprises soaking the veneer in the adhesive material for about 12 to about 24 hours.
The method according to any of the preceding claims, wherein step (b) further comprises placing the veneer and the adhesive material in a vacuum pressure impregnation chamber for about 3 to about 4 hours.
The method according to any of the preceding claims, further comprises weighing the plurality of the veneers.
The method according to any of the preceding claims, further comprises inspecting the plurality of the veneers to remove one or more defective veneers.
The method according to any of the preceding claims, wherein the adhesive material comprises a resin having a viscosity of about 5 to about 30 cP.
The method according to any of the preceding claims, wherein the method further comprises curing the plurality of the veneers for about 24 to about 36 hours.
An engineered wood formed from a plurality of veneers, wherein each of the plurality of veneers comprises a plurality of fully-penetrated holes, and an adhesive material adapted to bind the plurality of veneers together by filling the plurality of fully-penetrated holes.
