摘要： A multi-layer fire-resistance treatment (FRT) panel for use as structural sheathing. The wood structural panel may be OSB or plywood, coated or treated during the manufacturing process with a product that provides fire resistance. The treatment may be integrated with the material forming the wood structural panel, or may be a coating layer applied to the mat or mat layer. A burn-through layer also may be applied. A protective layer comprising a resin-impregnated paper overlay may be applied on one or both sides of the panel.

摘要： A method of making a natural fiber composite panel includes extracting bamboo fibers from bamboo and embedding the extracted bamboo fibers in a polymer matrix material. The bamboo includes bamboo fibers and lignin, and the step of extracting includes mechanically scraping the bamboo fibers to remove at least some of the lignin. In some cases, the bamboo is steamed, soaked in water, soaked in an acidic solution and/or soaked in an alkaline solution before mechanical scraping.

摘要： The invention relates to a method for producing OSB wood material panels, in particular OSB wood material panels having reduced emission of volatile organic compounds (VOCs), including the following steps: a) producing wood strands from suitable woods; b) torrefying at least some of the wood strands; c) glue-coating the torrefied wood strands and non-torrefied wood strands with at least one binder; d) scattering the glue-coated wood strands onto a conveyor belt; and e) pressing the glue-coated wood strands to form a wood material panel. The invention further relates to an OSB wood material panel that can be produced in accordance with said method and to the use of torrefied wood strands to reduce the emission of VOCs from OSB wood material panels.

摘要： A sheet manufacturing apparatus includes a defibrating unit configured to defibrate material containing fibers in the air, a classifying unit configured to classify by airflow defibrated material, which has been defibrated at the defibrating unit, into fiber material and waste material, a deposition unit configured to deposit the fiber material to create deposited material, a discharge blower configured to discharge the waste material by airflow from the classifying unit such that the waste material does not move toward a side of the deposition unit, a transfer blower configured to transfer by airflow the fiber material from the classifying unit to the deposition unit, and a forming unit configured to form a sheet by using the deposited material. When manufacturing by the sheet manufacturing apparatus starts, the discharge blower is driven before the transfer blower.

摘要： A liquid-pervious fibrous non-woven fabric includes staple fibers made of thermoplastic synthetic resin fused together which is formed on its upper surface with a plurality of ridges, and a plurality of grooves extending in parallel in a longitudinal direction. The ridges and grooves are arranged alternately in a transverse direction. On the upper surface, some of the staple fibers extend across the ridges to the adjacent grooves on each side of the ridges and are, in the respective grooves, fused to the staple fibers of a different type from the former staple fibers.

摘要： A biocomposite is produced from natural fiber fabrics embedded in a matrix of biosynthetic polyhydroxy-alkanoate (PHA) polymers. The PHA is synthesized using aerobic microbial biosynthesis using mixed bacterial cultures and a feedstock containing anaerobic degradation products such as methane and volatile fatty acids derived from microbial biodegradation of organic waste materials, which may include waste biocomposites. Monomers may be added to the synthesized PHA polymer to control mechanical properties of the resulting biocomposite. The natural fibers and/or PHA may be pretreated using various techniques to improve the bond between the fibers and the PHA resin matrix and water absorption resistance of the fibers. The composite may be a laminate of treated and untreated fabric layers, or differently treated layers, to achieve good in-service performance as well as rapid and/or optimal biogas production when taken out of service and put in an anaerobic environment to degrade.

摘要： The present invention provides the use of spider silk threads for the production of tissue implants for medical use. A scaffolding matrix is provided for implantation, which matrix is comprised of spider silk thread and/or segments of spider silk threads which are cross-linked. The cross-linked spider silk thread segments essentially maintain a three-dimensional shape into which it is formed by pressing between moulds. The three-dimensional shape obtainable by moulding is sufficiently stable to be used as an implant or for colonizing by mammalian cells while essentially maintaining the three-dimensional shape. In a further embodiment, the scaffolding matrix of cross-linked spider silk segments is at least partially covered by cells autologous or heterologous to the implant recipient. The matrix colonized with cells is obtainable by in vitro cultivation of isolated cells in suspension with the scaffolding matrix.
