System for and method of manufacturing hemp products
A manufactured hemp product comprising a plurality of adhesively bonded and pressed hemp strands where the majority of the hemp strands are of generally the same length and comprise a naturally-occurring, generally elongate internal structure extending generally along one axis of the strand that has been at least partially laterally broken and at least permeated by an adhesive. The hemp strands are oriented roughly parallel to one another along their length. The manufactured hemp product comprises an amount of adhesive between about 5% to about 49% by weight. The manufactured hemp product can be used as a wood substitute in terms of appearance and performance. The manufactured hemp products may have aesthetic and structural qualities that are suitable for high traffic, high visibility applications such as boards, blocks, beams, panels, flooring, furniture, building materials and other wood products.
Methods and compositions for preparing particle boards
An amorphous polylactic acid polymer having a weight average molecular weight in the range of about 35,000 to 180,000 is described. The polylactic acid polymer composition can be hammer milled without cryogenics result in the form of particles wherein 90% of the particles have particle size of about 250 m or less and the material has a glass transition temperature of between about 55 C. to about 58 C. and a relative viscosity of about 1.45 to about 1.95 centipoise.
Adhesive comprising copolymer having repeating unit carrying amide group and carboxyl and/or its ammonium salt and artificial board prepared therewith
The present disclosure relates to an adhesive comprising at least one of the following copolymer A: the copolymer A has at least one repeating unit carrying an amide group and a carboxyl and/or its ammonium salt and at least one other repeating unit different from the one carrying an amide group and a carboxyl and/or its ammonium salt. The present disclosure also relates to an artificial board formed of a lignocellulose material and the adhesive and a method for manufacturing the artificial board.
METHOD OF FORMING A COMPOSITE MATERIAL AND A COMPOSITE MATERIAL
A method of forming a composite material includes: a) providing a substrate with fibres, lignin and hemicellulose; b) partially removing the lignin and hemicellulose from the substrate; and c) compressing the remaining substrate to form a compressed substrate. A composite material formed by the method is also provided.
STACKABLE MOLDED ARTICLES, AND RELATED ASSEMBLIES AND METHODS
Molded articles are provided. An exemplary molded article includes an inner panel portion, a main body portion, and a contoured portion extending between and interconnecting the inner panel portion and the main body portion so as to surround the inner panel portion and be surrounded by the main body portion. The contoured portion includes contoured corner segments and contoured elongated segments extending between respective pairs of the contoured corner segments. The contoured corner segments have a first maximum thickness. The contoured elongated segments have a second maximum thickness that is greater than the first maximum thickness. Related methods, assemblies, and apparatus are also provided.

PROCESS FOR MANUFACTURING AND FINISHING IMPROVED ENGINEERED WOOD SIDING
An improved engineered wood product, and related methods, with improved actual and apparent surface quality. The product includes a high basis weight fines layer overlaying a strand matrix base layer, with one or more overlay layers. The fines layer may be placed between the overlay layers, if multiple overlays are present. The configuration of fines layer and overlay layer(s) minimizes the presence of sub-surface imperfections that may result in visible telegraphing on the exposed surface. A light pattern or texture may be embossed on the outermost overlay layer during the pressing process. Additionally, a paint primer layer or coating with added aggregate may be applied to help camouflage inherent sub-surface defects.
Casket and Method of Construction
A casket and method for manufacture of a casket is described, and more particularly, for a casket having walls constructed of fiberboard such as medium density fiberboard (MDF). The walls have outside cladding of MDF that is molded or extruded to provide surface contours such as raised and/or recessed features without having to attach such features as separate trim pieces to the walls. The resulting casket provides aesthetic characteristics and strength for use in funeral ceremonies.
Method for Preparing Cold-Pressing Adhesive and Cold-Pressing Processing System for Plant Fiber Boards
The invention relates to a method for preparing a cold-pressing adhesive and a cold-pressing processing system for plant fiber boards. The fiber board processing method comprises the following steps of: firstly, mixing plant fiber and an adhesive, and fully and uniformly stirring the mixture; then paving the uniformly mixed plant fiber and adhesive in a cold-pressing die set of a cold-pressing device for cold-pressing and curing to prepare a plant fiber block; cutting the plant fiber block into a plurality of plant fiber board blanks with a required thickness; and finally conducting edge cutting and sanding treatment on the plant fiber board blanks to obtain the plant fiber boards.
