摘要:
A method for producing a manufactured wood product using less desirable or discarded natural wood and a manufactured wood product produced by the described method. This inventive method comprises utilizing less desirable or discarded natural wood pieces by slicing the wood pieces into elongated strips that are then partially separated into elongate sections that maintain fibrous connectivity between the elongate sections. The elongate sections are dried and covered or impregnated with an adhesive. A second drying follows the adhesive application and the elongated strips are then arranged lengthwise in a mold for cold or hot pressing.

A laminated core manufacturing method for performing rotational lamination by conveying a band-shaped material to be stamped 10 to a die apparatus to successively perform presswork, stamping out and dropping manufactured core pieces 20 into a blanking die 21 and rotating the blanking die 21 by a predetermined angle, in which a positioning mechanism for the blanking die 21, which has rotational lamination guide pins and rotational lamination guide holes 23-30, is disposed inward from both ends in a width direction of the band-shaped material to be stamped 10 and temporary holes 13-16 for the rotational lamination guide pins to be inserted are provided in the band-shaped material to be stamped 10. The structure allows downsizing of the die apparatus.

The invention provides a coating process for electrical steel sheet using a varnish composition, comprising the steps of a) applying at least one coating layer of a varnish composition onto the surface of the electrical steel sheet wherein the varnish composition comprises (A) 1 to 95 wt % of at least one resin comprising nucleophilic groups selected from the group consisting of OH, NHR, SH, carboxylate and CH-acidic groups, and electrophilic groups which can react with the above mentioned nucleophilic groups, wherein the resin is capable of transacylation in its main chain and/or side chain(s), (B) 5 to 75 wt % of at least one organic solvent and/or water, (C) 0 to 40 wt % of at least one resin different from (A), (D) 0 to 10 wt % of at least one customary additive, (E) 0 to 40 wt % of at least one pigment, filler and/or nano-scaled particle and/or monomeric and/or polymeric element-organic compound, wherein the wt % based on the total weight of the varnish composition. b) curing the applied at least one coating layer. Reduced energy consumption while curing the coating and reduced or no formaldehyde generation upon curing can be provided.

A method for producing a polymer film includes: obtaining a load graph representing a functional relationship between a weight percentage of tissue forming nanoparticles in a polymer film and a maximum load of that polymer film; obtaining a stress graph representing a functional relationship between the weight percentage of tissue forming nanoparticles in a polymer film and maximum stress of that polymer film; determining a first weight percentage corresponding to a peak of the load graph and determining a second weight percentage corresponding to a peak of the stress graph; determining an optimal weight percentage based on the first and second weight percentage values; and producing a polymer film having tissue forming nanoparticles at the optimal weight percentage.
摘要:
A rigid, high bulk laminated board comprising a five layer laminate having a composite ply (10) consisting of a first and a second embossed ply (21, 22) and between them an un-embossed centre ply, each embossed ply (21, 22) having first embossed projections extending from their first side and having embossed projections from their second side, the first embossed projections are adhesively bonded to the un-embossed centre ply to form a composite ply (10), the laminate further having first and second flat outer plies (15, 16) adhesively bonded to both sides of the composite ply (10). Each embossed ply has alternating raised and lowered projections (23, 24) in the form of an identical cup-and-ball pattern. A method for the production of such a rigid laminated board is also described.
