    摘要： The invention is a board of non-timber hardwood-replacement lumber. The primary constituent is rinds of a grass selected from the group of grasses consisting of sugarcane and sorghum. The board has an integral mass of parallel elongate flattened rinds aligned along the length of the board, parallel to a board surface and joined together by adhesive bonding. A "cant" (from which the boards are made) is also disclosed and like the boards sawed from it, the cant is substantially void-free and of substantially constant density throughout its cross-section. The board is furniture-grade and exhibits grain characteristics very closely similar to natural hardwood.

    摘要： Substitute lumber pieces having strengths and densities substantially equivalent to lumber are cut from single layer panels of over about 1 and normally less than 4 inches thickness made from wood wafers. The wafers are oriented with their lengths having a mean deviation to the longitudinal length of the panel measured in the major plane of the panel in the range of 0 to 10 degrees and a mean deviation measured in a minimum longitudinal plane perpendicular to the major plane from 0 to about 5 degrees and have an average effective length of at least 8 inches (200 mm), and preferably an average thickness less than 0.15 inches (4 mm) and a width of at least 0.25 inches (6 mm). Lumber is made by cutting the panel longitudinally. Preferably the panels are formed to have a substantially uniform density profile throughout their thicknesses.

    摘要： It has now been found that when there is a partial or complete replacement of the sodium hydroxide that is used to make a sodium phenolate resole resin by a molar equivalent of potassium hydroxide, a far faster curing resin is obtained. Such potassium-modified phenolic resins exhibit significant improvement in cure speed without loss of flowability. To the contrary, these resins act as though they were lower molecular weight condensation products. Reduced application rates are possible. The combination of faster cure and lower application rates has allowed such resins to be used as effective adhesives for plywood, for example, with veneer and interior plies having a higher moisture content than was previously possible. Generally, resins according to the invention may contain from about 1% to about 14%, and preferably from about 1% to about 7% by weight, of potassium hydroxide, or more.

    摘要： An improved phenol formaldehyde resin not requiring fillers or extenders and capable of bonding wafers or veneers having a moisture content of 10% or above is disclosed. The adhesive composition is prepared by mixing together a caustic solution of a high molecular weight PF resin, a dispersion of PF resin which is characterized in that it can swell in aqueous caustic medium but not go into solution, and alkylene carbonates or phenol resorcinol formaldehyde resins. Optionally, borax is utilized. The disperse phase is made by converting a solution of PF resin into a fine particle size particulate form by precipitation, spray drying or freeze drying, and partially cross-linking the resin during or subsequent to the formation of the fine particle size dispersion. The PF resin is partially cross-linked by (a) heat, by (b) acid catalysis, or by (c) a reaction with cross-linking chemicals. Also disclosed is a wood product produced from veneers having moisture contents of 10% or above and incised to improve their permeability to gases and liquids.

    摘要： This application discloses a phenol-formaldehyde binding resin formed from phenol and formaldehyde in mole ratio of one mole of phenol to 2 to 3 moles of formaldehyde, the resin being modified by replacing from 5% to 50% of the phenol by an equivalent amount of a concentrated aqueous complex of phenolic and carbohydrate components from the process water from the steam digestion of wood chips without chemical addition, said resin being formed by heating said mixture of phenol, formaldehyde and aqueous complex with aqueous alkali to a temperature not exceeding about 100.degree. C. until a resin having a Brookfield viscosity of at least 35 centipoises is produced, all weights being determined on a dry basis; and a method of producing said resin by reacting a concentrated aqueous extract obtained from the steam digestion of wood chips with phenol and formaldehyde under alkaline conditions at a temperature not exceeding about 100.degree. C. until a resin with a Brookfield viscosity of at least about 35 cps is produced, the mole ratio of phenolic compounds (that is, the phenol plus the phenolic compounds in the aqueous extract) to formaldehyde being in the range from 1:2 to 1:3, the weight of concentrated aqueous extract being from 5% to 50% of the weight of the phenol, calculated on the dry weight of each material.
