〔産業上の利用分野〕
本発明は木材に染色液、合成樹脂液、柔軟剤、防腐剤、
等の処理液を含浸させる木材の処理方法に関するもので
ある。[Detailed Description of the Invention] [Industrial Application Field] The present invention applies dyeing liquid, synthetic resin liquid, softener, preservative,
The present invention relates to a method for treating wood by impregnating it with a treatment liquid such as the following.
従来、この種の処理液を木材に含浸させるには密閉容器
内に木材を投入して減圧状態として木材の導管から空気
や水分を追い呂した上で該処理液を注入して該木材の導
管内に該処理液を導入し、更に該密閉容器内を加圧して
該木材の導管内の処理液を木材組織内に浸透せしめる方
法が採用されていた。Conventionally, in order to impregnate wood with this type of treatment liquid, the wood is placed in a sealed container, the pressure is reduced, air and moisture are purged from the wood conduit, and the treatment liquid is injected into the wood conduit. A method has been adopted in which the treatment liquid is introduced into the wood pipe, and the inside of the sealed container is further pressurized to allow the treatment liquid in the wood conduit to penetrate into the wood tissue.
しかしながら、上記従来方法では処理液は主として木材
の導管内にとどまり、木材組織内への浸透が不充分であ
り、また細胞内にまで該処理液を浸透させることは不可
能であった。その結果処理液が木材中に均一に浸透せず
、処理が均一に行なわれず１例えば染色処理等の場合に
は染色むらの発生を解消することは困難であった。However, in the above-mentioned conventional method, the treatment liquid mainly remains in the conduit of the wood, and penetration into the wood tissue is insufficient, and it is also impossible for the treatment liquid to penetrate into the cells. As a result, the treatment liquid does not penetrate uniformly into the wood, and the treatment is not carried out uniformly, making it difficult to eliminate uneven staining, for example, in the case of dyeing treatment.
本発明は上記従来の課題を解決するための手段として、
密閉容器内に木材を投入して減圧状態とした上で処理液
を注入し、更に超音波を及ぼして該木材に該処理液を含
浸せしめるとともに該密閉容器内を加圧する木材の処理
方法を提供するものである。The present invention, as a means for solving the above-mentioned conventional problems,
Provided is a method for treating wood, in which wood is put into a sealed container, the pressure is reduced, a treatment liquid is injected, the wood is impregnated with the treatment liquid by applying ultrasonic waves, and the inside of the sealed container is pressurized. It is something to do.
本発明においては、密閉容器内に木材を投入して減圧状
態とするのであるが、通常は２０〜３００■Ｈｇ程度の
減圧度が適用される０次いで処理液を注入するのである
が、該処理液とは染色液、合成樹脂液、防腐剤等である
。該処理液を注入して木材を該処理液中に浸漬した状態
で超音波が及ぼされるが、該超音波の周波数は通常１５
−’−４０Ｋｃで超音波を及ぼす時間は通常５〜１０分
程度とする。超音波を及ぼしつ＼あるいは超音波を及ぼ
した後、該密閉容器内を加圧するが、この際及ぼされる
圧力は通常１〜３０気圧程度とする。In the present invention, the wood is put into a closed container and brought into a reduced pressure state. Usually, a degree of reduced pressure of about 20 to 300 μHg is applied, and then a treatment solution is injected. The liquid includes a dyeing liquid, a synthetic resin liquid, a preservative, etc. The treatment liquid is injected and the wood is immersed in the treatment liquid, and then ultrasonic waves are applied, and the frequency of the ultrasonic waves is usually 15.
The time for applying ultrasonic waves at -'-40 Kc is usually about 5 to 10 minutes. After applying ultrasonic waves or applying ultrasonic waves, the inside of the sealed container is pressurized, and the pressure applied at this time is usually about 1 to 30 atmospheres.
密閉容器内を減圧すると該密閉容器内の木材の導管内に
存在している空気や水分は追い出され、このような状態
において処理液を注入すると該木材の導管内に該処理液
が導入される。この際超音波を及ぼすとそのエネルギー
によって該処理液は導管内から木材組織内に浸透し更に
細胞膜を通過して細胞内にまで浸透する。そして密閉容
器内を加圧すると木材組織内に浸透し更に細胞膜内に浸
透した処理液は更に均一に木材組織内に行きわたる。When the pressure inside the sealed container is reduced, the air and moisture present in the wood conduit inside the sealed container are expelled, and when the treatment liquid is injected under such conditions, the treatment liquid is introduced into the wood conduit. . At this time, when ultrasonic waves are applied, the treatment liquid penetrates into the wood tissue from the inside of the conduit and further penetrates into the cells by passing through the cell membrane. When the inside of the sealed container is pressurized, the treatment liquid that has penetrated into the wood tissue and further penetrated into the cell membranes is evenly distributed throughout the wood tissue.
〔発明の効果〕
したがって本発明においては短時間で木材に処理液を浸
透させることが出来る。[Effects of the Invention] Therefore, in the present invention, the treatment liquid can be permeated into wood in a short time.
