摘要:
A composition for treating cellulosic materials is provided. The composition comprises a dispersion of micronized additives. The dispersion comprises additive particles with diameters in the range of 0.001 to 25 microns. Also provided is a method for the application of the additive-containing composition to wood, as well as wood products which have been treated with the composition.
摘要:
A composition for treating wood-based material including at least one C1-C7 monocarboxylic acid salt or C1-C7 monocarboxylic acid or a mixture thereof as active agent against deteriation of wood. The composition also includes alkyd emulsion of high unsaturated fatty acid content and/or aluminum ion containing compound in the form of polyaluminum formate in a same aqueous liquid carrier as the C1-C7 monocarboxylic acid salt or C1-C7 monocarboxylic acid or a mixture thereof.

摘要:
Disclosed are compositions and processes for the preservation of porous materials, particularly porous fibrous materials, such as wood, wood composites, other processed wood materials, paper, board, card, textiles, rope, cordage and leather. Also for horticultural and agricultural application to plants or growing media prevent the growth and spread of fungal and other disease. The compositions contain salts of one or more preservative metals and carboxylic acids having one or a plurality of hydroxyl groups rendered soluble by means of complex formation with boric acid or a water soluble salt thereof. Application of the compositions of this invention to the porous organic material may be by any means used with conventional preservative solutions, for example soaking, spraying, brushing and vacuum or pressure application or other contact of the solution with the material to be treated.
摘要:
A method for treating onychomycosis and skin conditions such as urushiol-induced allergic contact dermatitis comprises coating the affected nail or skin with a solution comprising an at least a primary diamine with modified diphenylmethane diisocyanates and a carrier solvent/reactant.
摘要:
This invention provides a method for preserving wood by treating the wood with a composition comprising a dispersion of colloidal silica or colloidal alumina particles in a solvent and one or more organic biocides.
摘要:
A wood preservative includes injectable particles comprising one or more sparingly soluble iron salts. The iron-based particles are sufficiently insoluble so as to not be easily removed by leaching but are sufficiently soluble to exhibit toxicity to primary organisms primarily responsible for the decay of the wood. Wood or a wood product may be impregnated with iron-based particles of the invention.
摘要:
An aqueous wood preservation composition containing inorganic polymers of one or more of the following metals is disclosed; aluminum (approximately 3.8%-7.0% as Al2O3), zirconium (approximately 5.25%-9.1% as ZrO2), copper (approximately 0.7%-8.8% as CuO) and a fixing agent such as acetic acid or sodium acetate. The pH is adjusted to be between 2.0-4.0 using an inorganic base such as copper carbonate. The invention includes wood and cellulose fibers treated by the composition of the present invention as well as methods of preserving wood and cellulose fibers using the compositions.

摘要:
A process for preparing a fire-resistant cellulosic material which comprises contacting cellulosic material with an aqueous solution of aluminum phosphate wherein the molar ratio of aluminum to phosphorous is less than 1:1, optionally containing a metal oxide, to form an initially treated cellulosic material containing aluminum phosphate and an increased amount of water, removing water from and curing said initially treated cellulosic material to form a fire-resistant cellulosic material. The cellulosic material is preferably wood and the wood is preferably a shingle or plywood.
摘要:
Comminuted wood is converted to a colored wood product useful as a mulch by feeding the comminuted wood into the lower end of an angularly upward positioned screw conveyor having an internal auger. The comminuted wood is contacted in the lower end of the conveyor by a liquid color-imparting agent, preferably an aqueous solution containing iron oxide pigment, carbon black pigment or a mixture of both pigments. After contacting, rotation of the auger draws the moist colored wood product towards the upper end, permitting runoff of excess liquid agent, which returns by gravity to the basin for further contacting with newly-fed comminuted wood. Colored wood product discharges through a chute at the upper end of the conveyor for further drying, if necessary.
