Abstract
PURPOSE:To carry out dimension stabilization process inexpensively by injecting water solution mainly composed of urea and/or methylol urea into a timber and then volatilizing the water content. CONSTITUTION:Besides urea and/or methylol urea as main component, a mildewproofing agent, a termite-proofing agent, an permeating agent and if required, D-glucose are added to water, sufficiently agitated at the room temperature to 40 deg.C to prepare uniform solution. In order to inject the injection solution thus prepared, the injection liquid is filled in a closed container in which a timber is immersed, and the degree of vacuum in the closed container is set at 160mmHg or less and the pressure is reduced for 30 minutes to one hour, and then pressurized up to approximately 5-15kg/cm<2> and the injection solution is injected for 2-3 hours, and then left at the room temperature and normal pressure for 2-3 hours, or left under the normal pressure for 2-7 days to permeate sufficiently the injection solution to cell walls of the timber. Then, the timber into which the injection solution is permeated is discharged out of the closed container to volatilize the water content. The timber is left under the normal temperature for 2-3 days, and then dried at 50-60 deg.C for several days.
Description
【発明の詳細な説明】 く技術の分野） この発明は木材の寸法安定化処理方法に関する。[Detailed description of the invention] field of technology) The present invention relates to a method for dimensional stabilizing wood.
ざらに詳しくは木材を処理し、木材そのものは勿論その
木材を使用した建造物或いは家具の収縮、膨張或いは変
形を未然に防止する処理方法に関する。More specifically, the present invention relates to a method of treating wood to prevent shrinkage, expansion, or deformation of the wood itself, as well as buildings or furniture made of the wood.

施されていた。<Conventional technology> Conventionally, in order to stabilize the dimensions of wood, 1400 molecules were added to the wood.
A method of injecting an aqueous solution of polyethylene glycol of 1,500 to 1,500 ml and then evaporating the water, or a method of performing a similar treatment using an aqueous solution of an inorganic i* such as calcium chloride has been practiced.
（発明が解決しようとする問題点〉
ポリエチレングリコールは高価である上、ポリエチレン
グリコールで５１！ｌ理した木材は、若干べとついて肌
ざわりが悪いという欠点があった。(Problems to be Solved by the Invention) Polyethylene glycol is expensive, and wood treated with polyethylene glycol has the disadvantage that it is slightly sticky and has a poor texture.
また無機塩類で処理した木材は、これに接触する金属を
腐食させる欠点があった。Additionally, wood treated with inorganic salts has the disadvantage of corroding metals that come into contact with it.
