摘要:
A wood preservative composition for protecting wood and wood products against water damage and/or insect damage, comprising a boron-containing material; and a silane.
摘要:
The invention relates to a method for treating wood in order to improve its properties of use and storage, and to thus obtained treated wood product. In the method the wood to be treated is contacted with a treatment composition comprising monoester, diester or triester or a mixture thereof formed by a water soluble C 1 -C 1O alcohol and formic acid as an equilibrium solution. In addition, the invention relates to specific treatment solution compositions.
摘要:
This invention is related to a wood preservative composition comprising i) at least one active ingredient, and ii) a carrier system containing at least 10% w/w of a solvent selected from one or more ester compounds of the formula (I) wherein: R and R' are independently selected from Ci-Cβ-alkyl groups, and wherein the carbon chains of alkyl groups of 3 or more carbon atoms may be straight-chained or branched; and wherein the at least one active ingredient is substantially soluble in the earner system. The preservative compositions may be used to treat wood based materials, and the ester solvent may optionally be recovered following the treatment. Formula (I).
摘要:
The present invention relates to the use of alkoxylated amines for treating wood and other cellulose materials in order to enhance their water repellent properties and to reduce water uptake when treated wood or other cellulose materials are brought into contact with water.
摘要:
A process for treating wood comprising at least partially penetrating it with a urethane- or acrylate-based fluoro-material. Also, wood produced by the process.
摘要:
The invention relates to a wood treatment solution which does not contain heavy metals and which contains an impregnation agent that is an alkali metal salt or alkaline-earth metal salt of formic acid or propionic acid. The invention also relates to a process for treating wood in order to improve its preservation, in which process wood is treated with the said wood treatment solution.
摘要:
Die Erfindung betrifft ein Holzschutzmittel mit einer Viskosität von höchstens 55 mm 2 /s bei 25 °C und einem Schmelzpunkt von ≤ (kleiner gleich) 25 °C, das im Wesentlichen aufgebaut ist aus einem oder mehreren Fettsäureestern der allgemeinen Formel
R 1 -C(O)-O-R 2
wobei der Rest R 1 ein einfach ungesättigter, linearer Alkylrest mit 12 bis 20 C-Atomen ist, der Rest R 2 ein substituierter oder unsubstituierter, gesättigter oder ungesättigter, linearer oder verzweigter Alkylrest mit 1 bis 20 C-Atomen ist und ggf weitere darin gelöste Hilfsstoffe, wie Lichtschutzmittel, Fungizide, Bakteriostatika und Pigmente enthält.
摘要:
A method for producing a composite product including a substrate material and a binder, wherein either the binder includes a plastics material in an emulsion form, or a plastics material is added to an emulsion including the substrate material. The invention is also directed to composite products including a particulate substrate and particles of a plastics material therein.
摘要:
The invention relates to a method for rendering lignocelluloses hydrophobic and a wooden material made from lignocelluloses. The lignocelluloses are treated with a paraffin-based agent for rendering material hydrophobic and, optionally after a drying process, compressed to give the wooden material. Of significance is that the hydrophobic agent is at partly made from Fischer-Tropsch paraffin.
摘要:
Methods for esterifying hydroxyl groups in cellulose, hemicellulose, and lignin in wood are described, wherein the wood is chosen from loblolly, slash, shortleaf, longleaf or radiata pines. Methods can include solvent drying techniques and heating provided by electromagnetic radiation, such as microwave, and radiofrequency. Products made from the methods are described that have greater decay resistance and dimensional stability as compared with non-esterified wood products.
