A method for determining the wettability of wood or woody materials, a colorimetric solution used in the method, and a kit for performing the method.

Abstract

In one embodiment, the present invention provides a method for accurately evaluating the wettability of a wood preservative treated with a wood preservative containing a quaternary ammonium compound. In another embodiment, the present invention relates to a method for determining the wettability of wood or wood material, which is a method for determining the wettability of a reagent containing a quaternary ammonium compound on wood or wood material, and includes: contacting a colorimetric solution containing tetrabromophenolphthalein ethyl ester (TBPE) or eosin Y as the active ingredient with the wood or wood material treated with the aforementioned reagent to conduct a colorimetric reaction.

Claims

1. A method for determining the wettability of wood or wood-based materials, comprising determining the wettability of a reagent containing a quaternary ammonium compound on wood or wood-based materials, and including: A colorimetric reaction is carried out by contacting a colorimetric solution containing tetrabromophenolphthalein (TBPE) as the active ingredient with wood or wood-based materials treated with the above-mentioned reagent.

2. The method of claim 1, wherein the agent containing the quaternary ammonium compound is a wood preservative containing the quaternary ammonium compound.

3. The method of claim 1 or 2, wherein the content of TBPE in the colorimetric solution is 0.005% to 10% by mass.

4. A colorimetric solution for determining the wettability of wood or woody materials, wherein the wettability determination is a determination of the wettability of wood or woody materials by an agent containing a quaternary ammonium compound, and the colorimetric solution contains tetrabromophenolphthalein ethyl ester (TBPE) as an active ingredient.

5. A kit for determining the wettability of wood or wood-based materials, wherein the wettability determination is a determination of the wettability of wood or wood-based materials by an agent containing a quaternary ammonium compound, comprising tetrabromophenolphthalein ethyl ester (TBPE) and an instruction manual describing a method for testing the wettability of wood.

6. A kit for the preservation treatment of wood or woody materials, comprising: a wood preservative with a quaternary ammonium compound as the active ingredient; and a colorimetric solution containing tetrabromophenolphthalein (TBPE) as the active ingredient for determining the wettability of the wood preservative on wood.
