ENHANCED PERFORMANCE OF WOOD AND ENGINEERED WOOD PRODUCTS USING COMBINED DURABILITY AND FLAME RETARDANCY

A treatment process and wood products thereof including a product formulation of a single phase solution combining a wood preservative (durable component) with a Flame Retardant component (FR) to produce a durable Flame Retardant (dFR) treated wood product. The durable component comprises a range of copper based and non-copper based wood preservatives, while the FR component comprises alkali metal silicates and alkali metal aluminate compounds. The dFR working solution undergoes chemical impregnation (treatment) followed by a heat (fixation) process step that locks the chemical into the wood making it non-leachable. The dFR treated wood products are tested for their enhanced fire performance properties. When heated, wood undergoes thermal degradation and combustion producing gases, vapors, tars and chars. Using a cone calorimeter burn test method, dFR treated wood products show a significant reduction in heat release rate, mass loss rate and smoke generated values compared to untreated radiate pine.

Method for making nano veneer
10322523 · 2019-06-18 ·

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.
