Abstract
A process for producing nano veneers generally involving: placing a veneer to be treated in a vacuum vessel; adding a nano carbon powder and nano silicon dioxide suspension in the vacuum vessel; reducing the pressure in the vessel over a first period of time; increasing the pressure in the vessel; letting the contents of the vessel rest over a second period of time. The veneer may optionally be subjected to ultrasonic treatment, ultraviolet solidification treatment, or subsequent pressurization treatments to obtain the final nano veneer product. As a result, veneer manufactured using embodiments of the present invention will have the advantages of high strength, wear resistance, pollution resistance, acid and alkali resistance, water segregation and decay resistance.

A method for making veneers, comprising:
- placing a veneer wood in a vacuum vessel;
- adding a nano carbon powder and a nano silicon dioxide suspension to the vacuum vessel;
- reducing the pressure in the vessel to a first pressure over a first period of time;
- maintaining the vessel at the first pressure during the first period of time;
- increasing the pressure in the vessel to a second pressure;
- maintaining the vessel at the second pressure for a second period of time;
- removing the veneer wood from the vacuum vessel;
- and
- drying the veneer.
A method for making veneers, comprising:
- placing a veneer wood in a vacuum vessel;
- adding from about 10 to about 15 weight percent (based on the weight of the veneer wood) of a nano carbon powder and from about 22 to about 37 weight percent (based on the weight of the veneer wood) nano silicon dioxide to the vacuum vessel, with the nano silicon dioxide in suspension form;
- reducing the pressure in the vessel to a first pressure over a first period of time;
- maintaining the vessel at the first pressure during the first period of time;
- increasing the pressure in the vessel to a second pressure;
- maintaining the vessel at the second pressure for a second period of time of from about 5 to about 8 hours;
- removing the veneer wood from the vacuum vessel;
- and
- drying the veneer.
