Description

[Detailed description of the invention] The present invention relates to a method for treating tree-like wood.

After 14 sc, the strips cut by a rotary laser were cut into appropriate dimensions, laminated with spacers interposed therebetween, and immersed in a decolorizing solution to be decolorized. However, pigeonholes that are bleached in this way require cutting of strips of veneer,
Since work such as lamination using spacers is complicated, there has been a desire to develop a method that can directly decolorize strip-shaped veneers.

This release@Mori, in view of these circumstances, is a bottle of Kuki, so...
A strip of wood coated with a treatment solution is wound around a winding shaft with a spacer interposed in its entirety or a portion of the line, and the wound body is placed in a treatment chamber and heated steam is blown into the treatment chamber. Its gist is to:

That is, by doing this, the heated steam enters the voids in the wood created by the spacer and is rolled up to heat the entire round strip-shaped wood, and the heating causes the decolorizing III type treatment liquid to be applied to the wood. The action is accelerated and the entire strip of wood is treated uniformly. Therefore, the belt-shaped wood can be easily processed without cutting or the like.

Next, the present invention will be explained based on one example.

As shown in FIG. 1, a corrugated stainless steel plate 2 is inserted between two folded stainless steel plates 10 to form a stainless steel spacer 8, and this is bent into a substantially circular shape as shown in FIG.

On the other hand, as shown in FIG. 8, the raw wood 4 is passed through a rotary laser (not shown) to form a strip-shaped veneer 5, which is continuously passed through a decolorizing liquid 7 in a decolorizing tank 6. Attach. 8 is a dipping roll, and 9 is a feed roll. and,
With the stainless steel spacer 8 inserted in an appropriate position, the film is continuously wound around a hollow winding shaft 10. In this way, all the strip-shaped veneers 6 are wound up. This is the fourth
As shown in the figure. Next, as shown in FIG.
1 is placed in the heating chamber 12, both ends of the winding shaft 100 are supported by a support part (not shown) K, so that the winding body 11 is suspended in the air, and in this state, a steam supply pipe is connected to one end of the winding shaft 10. 18 is connected, and the cock 14 is operated to blow heated steam into the winding shaft 10. The steam blown from one end of the winding shaft 10 passes through the inside of the winding shaft 10 and is blown out from the other end. Then it hits the wall of the heating chamber 12, turns over and returns to the steam supply pipe side of the heating chamber 12, and from there passes through the inside of the stainless steel spacer 8 in the winding body li and blows out to the opposite steam supply pipe side of the heating chamber 12. . In this case, the heated steam is heated to the hollow winding shaft l.
When passing through O and the stainless steel spacer 8, the steam flowing on the outer peripheral surface of the winding body 11 heats the veneer around it (the veneer inside the winding body 11). The veneer on the outer peripheral side of the body 11 is heated. In this way, the roll tta is heated by the heated steam from the inside and from the outer circumferential side, so that the entire body is heated almost uniformly, and the decolorizing liquid 7 adhering to the single body is thereby uniformly activated and shaped into a strip. Veneer 5
Once the entire area is dry, the color will be evenly decolored.

In this way, according to this method, the strip-shaped veneer 5 can be uniformly dried and bleached as it is without cutting, and the bleaching work can be significantly simplified.

Although the above example describes the decolorization of the strip-shaped veneer 5, this invention is applicable not only to decolorization but also to dyeing and other mysK.
can also be applied. In addition, the heating steam is on the winding axis lO
Blow in from the heating chamber 1, not the K11l constant.
Heated steam may be sent into the heating chamber 12 so that a flow of heated steam is generated within the heating chamber 12. Furthermore, the winding shaft lO may be a solid shaft instead of a hollow shaft. In this case, the book and the surrounding veneer are heated by heat conduction.

In this invention, since the wood strips are processed by K as described above, the processing can be performed extremely easily without the need for complicated operations such as cutting the wood strips and stacking them with spacers as in the past. It is possible.

Then, the material was wound around a hollow winding shaft 10. In this case, stainless steel spacers 8 were sandwiched between them so that the spacer interval 4 was 200 mm as shown in FIG. 16 is a strip-shaped veneer. Next, this III deposit 16 was put into a heating chamber 12 as shown in FIG. After heating for 1 hour, the strip veneer 16 was removed and dried completely. :1
