Unknown
A wooden container provided for the maturation of a wine or a spirit, comprising wood pieces (6) elongated in the direction of the wood fibers, assembled together in the width in order to constitute a closed container, characterized in that it includes at least one wood piece (6) which has an inner surface in which at least one groove (36) is arranged forming an angle relative to the wood fibers representing the longitudinal axis of growth of the shaft, in order to obtain a cut of these fibers intended to be exposed to the liquid.
Method For Preparing Functional Engineered Wood
The present invention relates to furniture panels, and more particularly, to a method for preparing functional engineered wood. It includes the following steps: make veneer blanks by rotary cutting or splicing, and cut the veneer blanks into desired dimensions to obtain veneers A. Soak the veneers A in a ternary mixed solution of a biomass nanocellulose solubilizer, a fire retardant and an acid dye for toughening, fire retardation and dyeing to obtain veneers B. Add a formaldehyde decomposing powder into a modified MUF adhesive, mix them up, coat the veneers B with the mixture to obtain veneers C. Assemble and cold-press the veneers C to obtain flitches D, and saw the flitches D into desired patterns and dimensions to obtain finished products.
WOOD MODIFICATION TO ENHANCE FIRE RETARDANCY
The co-formulation of a wood preservative (‘treated’) with an inorganic (alkali metal silicates) based flame retardant which undergoes chemical impregnation. Once the ‘treated flame retardant” working solution has fully penetrated (sapwood) into the wood, it then undergoes a heat (fixation) process using various heating schedules to achieve chemical fixation. The treated flame retardant Modified Wood [tfrMW] products are then tested for their enhanced fire performance properties. When heated, wood undergoes thermal degradation and combustion producing gases, vapours, tars & chars. Using the ‘cone calorimeter’ test method, the [tfrMW] products showed a significant reduction in the following parameters: heat release rate (HRR), mass loss rate (MLR) & smoke generated (SEA) values compared to untreated radiata pine.
NOVEL LAYERED MATERIALS AND THEIR USE
A layered material includes a first carrier material and a second carrier material. The first carrier material is coated or saturated with a modified bitumen. The modified bitumen is a bitumen to which is added an agent selected from a wax, a silicone oil, stearic acid, alkene ketene dimer (AKD), alkenyl succinic anhydride (ASA), and mixtures thereof. The first carrier material is continuously attached to the second carrier material.
A LARGE-SIZE DESERT SALIX WOOD BUILDING MATERIAL AND MANUFACTURING METHOD THEREOF
The present invention relates to a large-size desert salix wood building material and manufacturing method thereof. The manufacturing method comprises the following steps: desert salix growing in a same period is used as raw materials; desert salix branches are peeled and degreased by methods of heating stewing and water pressure blasting; gum-dipped desert salix strand silks are dried, dyed and assembled synchronously by one time, and then are pressed, glued and cured, and thereby a large-size desert salix wood building material of a size of (12000-30000 mm)×400 mm×300 mm is obtained. The present invention has the following beneficial effects: desert salix planted and cultivated in a same period in a desert is adopted as raw material, and is processed to produce a large-size desert salix wood building material, which has accordant material properties, excellent mechanical performance and controllable quality, providing an engineering structure material which is ecological green, energy saving and environmentally protective for building industry, so that a natural forest resource is facilitated to be saved, and the consumption of a fossil resource is reduced; specifically, a sustainable industrial method for preventing and controlling desertification is provided, so that a positive effect on repair and protection of human ecological environment is achieved.
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.
PURIFICATION OF WOOD ACETYLATION FLUID
Disclosed is a method of purification of utilized acetylation fluid recovered from a process of acetylating wood. The method involves subjecting the recovered acetylation fluid to cooling crystallization. By this method terpene and terpenoid impurities are removed, as well as other impurities. Disclosed is also a method of acetylating wood resulting in acetylated wood and utilized acetylation fluid comprising acetic acid, and purifying the utilized acetylation fluid by cooling crystallization.
Method for continuous acetylation of wood elements
The disclosure relates to a method for continuous acetylation of wood elements. The acetylation is conducted with an acetylation medium at a pressure of at least 1.5 barg in a substantially oxygen free environment. Alternatively, the method includes the steps of: (a) feeding wood elements in a substantially oxygen free environment to a continuous acetylation reactor, and (b) treating the wood elements with an acetylation medium in the continuous acetylation reactor under wood acetylation reaction conditions, at a pressure of at least 1.5 barg. The process can acetylate wood elements to a high acetyl content in an efficient way, without compromising on the quality of the material. The acetylated wood elements can be used in the production of medium density fibreboards with superior qualities such as dimensional stability and durability.
