摘要:
A thermal insulation material is made of a plurality of insulating components. The plurality of insulating components includes a first insulating component made of wood shavings. The plurality of insulating components includes a second insulating component made of cellulose fibers, wherein the cellulose fibers are arranged in voids formed between the wood shavings. The cellulose fibers of the second insulating component are produced from decor paper or sanitary paper.

Coconut husk and coconut shells are primarily considered agricultural waste. Therefore, coconut shells are often burned, which is terrible for the environment and contributes significantly to CO2 and methane emissions. Thus, the present invention provides an eco-friendly use for coconut waste by turning coconut fibers into thermo-acoustic insulation. The present invention also describes methods of producing said insulating compositions.

The disclosure proposes a fibreboard made of lignocellulose-containing fibres, in particular wood fibres and a binding agent for providing a fibreboard which enables to combine a high stability, on the one hand, and a comparatively small weight, on the other hand, and which can nevertheless be manufactured with a minor financial effort.
摘要:
A unitary, fiber-containing composite comprises (a) a first region comprising a plurality of first binder fibers and a plurality of bast fibers, (b) a second region disposed above the first region, the second region comprising a plurality of second binder fibers and a plurality of bast fibers, and (c) a transitional region disposed between the first region and the second region. The transitional region comprises concentrations of the first binder fiber, the second binder fiber, and the bast fiber. The concentration of the first binder fiber in the first transitional region is greatest proximate to the first region and least proximate to the second region, and the concentration of the second binder fiber and the bast fiber in the first transitional region is greatest proximate to the second region and least proximate to the first region. A method for producing a unitary, fiber-containing composite is also described.
摘要:
Cellulosic fiber composites and methods for preparing cellulosic fiber composites are provided. The cellulosic fiber composites comprise cellulosic material and a resin binder. The resin binder comprises protein hydrolysates and a synthetic resin. The synthetic resin can be phenolic resin, isocyanate resin, or combinations thereof. The protein hydrolysates provide a composite with a reduced amount of petrochemicals. The composite contains an amount of resin binder sufficient to bind the cellulosic material. The composite can also contain a silicone, silane, or combination thereof. The method employs a low moisture-content mat that does not require drying prior to pressing. Additional methods can be employed to produce finished cellulosic fiber composite articles.
摘要:
A method of preparing a cellulosic fiber composite is provided comprising mixing protein hydrolysates and a synthetic resin to produce a resin binder. The synthetic resin can be phenolic resin, isocyanate resin, or combinations thereof. The method further comprises mixing the resin binder with a cellulosic material to form a cellulosic material/resin binder blend, felting the blend to form a low-moisture content mat, and pressing the mat at an elevated temperature and pressure, producing the cellulosic fiber composite. The amount of the resin binder can be between about 2% and about 15% of the dry weight of the cellulosic material. The protein hydrolysates provide a composite with a reduced amount of petrochemicals. The composite can also contain a silicone, silane, or combination thereof. The low moisture-content mat does not require drying prior to pressing. Additional methods can be employed to produce finished cellulosic fiber composite articles.
摘要:
A method or process for a system for applying high, elevated levels of zinc borate additives to composite or manufactured wood panels, such as oriented strand board, for improved surface antifungal and anti-termite properties. Zinc borate is applied to one or more surface layers of a manufactured wood panel at approximately 2.0% (m/m) or higher, more preferably above 2.0% (m/m) to approximately 2.5% (m/m), which produces the surprising result of resisting surface fungal growth. In particular, OSB panels generated from Aspen and Southern Yellow Pine (SYP) wood species are successfully treated with zinc borate levels of at least approximately 2.0% (m/m), and found to resist surface fungal growth.
