Method for producing aqueous dispersions for use as a flame retardant additive to wood composite panels
The current invention concerns a method for producing an aqueous dispersion suitable for being used as a flame retardant additive to wood composite panels. At least one pH-regulator, at least one inorganic thickener, and optionally at least one smoke suppressing agent is added to a premix while maintaining the actuation of wet-milling systems until the dispersion is obtained.
METHOD FOR PRODUCING ULTRA-STABLE AND ENHANCED SOLID WOOD FLOORING FOR UNDER-FLOOR HEATING VIA SURFACE COMPRESSION TECHNIQUE
A method for producing an ultra-stable and enhanced solid wood flooring for under-floor heating via surface compression technique includes: subjecting, while subjecting a solid wood to surface compression and enhancement, the solid wood to primary stabilization treatment by controlling a temperature of a hot pressing plate to obtain a compressed enhanced solid wood; putting the compressed enhanced solid wood into a heat treatment tank; and subjecting the compressed enhanced solid wood to secondary stabilization treatment by controlling a pressure and a temperature of steam or air in the heat treatment tank and a treatment time to obtain a finished product. The ultra-stable surface-compressed enhanced solid wood flooring produced by the method features high dimensional stability, low set-recovery after water absorption, and desired moisture and heat resistance.
Synergistic fungicidal compositions and methods of use
Described is a broad spectrum, synergistic fungicidal composition when used for the preservation of a glued wood product comprising as active ingredients: (A) triadimefon, and (B) cyproconazole characterised in that the weight ratio of (A):(B) is from about 20:1 to about 1:1, the composition being further characterised in that the application rate for the composition is from about 10 gai/m.sup.3 to about 6,000 gai/m.sup.3.
METHOD FOR SCAVENGING FREE FORMALDEHYDE USING MULTIFUNCTIONAL SCAVENGER FOR WOODEN COMPOSITE PRODUCTS WITH UREA-FORMALDEHYDE RESIN
The application describes a method of scavenging formaldehyde from a wooden composite comprising urea-formaldehyde or melamine urea-formaldehyde by providing a combination of formaldehyde scavengers in the face and core layers of the composite and further describes the composite produced with these scavengers.
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.
Methods and Compositions for Use in Glued-Wood Products
The present invention relates to a composition for increasing the retention of a biocide in a glueline-treated glued-wood product, a method for increasing the retention of a biocide in a glueline-treated glued-wood product, a glueline-treated glued-wood product, a glue for producing a glueline-treated glued-wood product, and the use of a composition for increasing the retention of a biocide in a glued-wood product.
CROSS-LAMINATED TIMBER PANEL HAVING A CONDUIT THEREIN AND ATTACHABLE FITTING
A fitting attachable to a cross-laminated panel provides a chase, plumbing space, airflow duct, or wiring route on an edge of the cross-laminated panel. The fitting may run between edges of multiple cross-laminated panels that contain integral hollow members, forming a customizable network of contiguous coplanar routing paths, accessible without installing pipes and wires behind, or in front of the cross-laminated panels. The fitting may also provide a vertical chase for single or multiple cross-laminated panels. The fitting takes advantage of one or more hollow members in the cross-laminated panels to provide contiguous routing paths for wires, pipes, and venting within the cross-laminated panels themselves, extending across any layout of multiple cross-laminated panels. The fitting may additionally serve as mechanical support for attachment of adjacent panels. Further, the fitting may provide structural connection for the CLT panels as required to meet structural code requirements for the building.
Methods and Compositions for Use in Glued-Wood Products
The present invention relates to a composition for increasing the retention of a biocide in a glueline-treated glued-wood product, a method for increasing the retention of a biocide in a glueline-treated glued-wood product, a glueline-treated glued-wood product, a glue for producing a glueline-treated glued-wood product, and the use of a composition for increasing the retention of a biocide in a glued-wood product.
FIRE-RESISTANT BAMBOO STRUCTURAL BUILDING MATERIAL
Bamboo lumber products and fabrication techniques thereof are provided. Thick-wall bamboo culm is cut into multiple slats, each made up of a solid portion of culm. The slats are laminated, joined, or otherwise combined to form solid panels, boards, or other lumber products. The use of thick-walled bamboo and associated processes as disclosed allows for lumber products that have a lower glue-to-bamboo ratio and therefore provide superior characteristics compared to conventional techniques and products.
Durable palm fiber composite material and preparing method thereof
A durable palm fiber composite material is obtained by impregnating an unprocessed palm bark in a resin adhesive solution prepared by using a palm leaf as a raw material and then hot-pressing. The palm bark is dried under a natural state without additional processing. The palm leaf is made into a tannin resin adhesive solution under the effect of additives such as furfuryl alcohol, paraformaldehyde, and others. A pH value of the adhesive solution is controlled to be 9-11. A solid content is 40-60%. An adhesive amount applied to the palm bark by the resin adhesive solution is 800-1500 g/m.sup.2. Odd number of layers (three or more layers) of palm barks that are impregnated by the resin adhesive solution and are hot-pressed to the composite material. Hot-pressed parameters are as follows: the temperature is 150-180° C. the unit pressure is 0.8-1.5 MPa, and the time is 10-30 s/mm.
