摘要:
A composition for improving the dimensional stability of wood and other cellulosic materials is provided. The composition comprises a polymer which is present in dispersion, emulsion, or solvated form; and/or a water repellent. Also provided is a method for improving the dimensional stability of wood and other cellulosic substrates which comprises treating the substrate with the composition such that the polymer forms a film on the surface and inner structures of the wood.
摘要:
Provided is a composition for the preservation of wood and other cellulosic materials. The composition comprises a dispersion of micronized inorganic compounds and/or organic biocides in an organic carrier. Also provided is a method for making the composition.
摘要:
A wood preservative composition comprising micronized particles of organic biocide is provided. The composition comprises a dispersion comprising particles in the range of 0.001 to 25 microns. Also provided is a method for the application of the preservative composition to wood. In addition, wood products which have been treated with the preservative composition are also provided.
摘要:
The present invention provides wood preservative compositions comprising micronized particles. In one embodiment, the composition comprises dispersions of micronized metal or metal compounds. In another embodiment, the wood preservative composition comprises an inorganic component comprising a metal or metal compound and organic biocide. When the composition comprises an inorganic component and an organic biocide, the inorganic component or the organic biocide or both are present as micronized particles. When compositions of the present invention are used for preservation of wood, the micronized particles can be observed as uniformly distributed within the wood and there is minimal leaching of the metal and biocide from the wood.
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:
The present invention provides wood preservative and flame retardant compositions having low leachability comprising micronized boron compounds and, optionally, one or more organic biocides which may be micronized. Also provided is a method for applying the composition to wood and wood products comprising impregnating the wood with the composition.
摘要:
The present invention provides compositions which can be used to preserve and color wood, as well as methods of using the solution to both preserve and color wood. The composition is an alkaline solution which comprises one or more metal compounds or metal complexes and one or more cationic dyes
摘要:
The present invention relates to a method and a wood preserving composition which is free of poly-aspartic acid and its derivatives and comprises mixtures of a metal compound, complexing agents selected from ethanolamines, polyethylenimine, ammonia or a mixture of these compounds, and a vinyl based polymer selected from poly(vinyl alcohol) (PVA), poly(acrylamide) (PA), poly(N-vinyl pyrrolidone) (PVP) and poly(N-isopropyl acrylamide) (PNIPAM). The resulting metal amine solution can then be used to formulate a variety of metal-based cellulosic material preserving products.
摘要:
The present invention provides wood preservative compositions comprising micronized particles. In one embodiment, the composition comprises dispersions of micronized metal or metal compounds. In another embodiment, the wood preservative composition comprises an inorganic biocide comprising a metal or metal compound and organic biocide. When the composition comprises an inorganic biocide and an organic biocide, the inorganic biocide or the organic biocide or both are present as micronized particles. When compositions of the present invention are used for preservation of wood, there is minimal leaching of the metal and biocide from the wood.
摘要:
Provided is a preservation composition having a large-particle distribution which can effectively penetrate and preserve wood. The composition comprises a particulate dispersion of biocidal particles such that at least about 3 weight percent of the particles have diameters are greater than about 0.5 micron, and at least 98 wt % of the particles have diameters of less than about 10 microns. Also provided is a method for preserving wood with the composition.
