【発明の詳細な説明】
本願は、木材の特色を残して、木材内に有機物質を満た
す複合木材にして、木材の欠点を補強するための製造法
に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present application relates to a manufacturing method for reinforcing defects in wood by making it into composite wood that fills the wood with organic substances while retaining the characteristics of wood.
本発明を用いる応用範囲は、木材加工の多方面にも応用
できる。 ＩＮえば、現在の防腐上白や防虫！３埋木材
でも分かるように、それぞれの処理した辺周部しか薬剤
を注入できない、その処理をした木材を加工すれば、薬
剤が注入されていない部分が出てくるのが現状である。The scope of application of the present invention is also applicable to many aspects of wood processing. If it is IN, the current antiseptic coating and insect repellent! As you can see with 3-buried wood, chemicals can only be injected around the treated edges of each piece of wood.Currently, when treated wood is processed, there are parts that have not been injected with chemicals.
木材に染色液や防火液を注入しようとしても、バルサの
ように木材組織の粗い樹木以外では、薬品を木材に注入
することは不可能である。Even if you try to inject dyeing liquid or fireproofing liquid into wood, it is impossible to inject chemicals into wood except for trees with coarse wood texture such as balsa.
本発明の応用範囲が余りにも多いので、それぞれを説明
していては切りが無いので、現在世界的に問題となって
いる地球温暖化防止のために必要な植林対策にも使用し
うろことを上げて、本発明を説明することにする。The range of applications of the present invention is so large that it would be pointless to explain each one of them, so I would like to explain how scales can also be used for afforestation measures that are necessary to prevent global warming, which is currently a worldwide problem. The present invention will now be explained.
現在世界的に炭酸ガス増加による地球温暖化防止対策の
必要が問題になっている。工場がら煙の排出のない日本
では、この炭酸ガスの排出量を減少させるには、植林量
を増加させるのが一番簡単である。Currently, the need for measures to prevent global warming due to the increase in carbon dioxide gas has become an issue worldwide. In Japan, where factories do not emit smoke, the easiest way to reduce carbon dioxide emissions is to increase the amount of afforestation.
しかし、日本で主として植林されている打栓の針葉樹は

要とする現在の植林の仕方では、なおのこと植林に投資
するものは、ますます少なくなる。However, the plugged coniferous trees that are mainly planted in Japan require a 60-year cycle. In Japan, where gold M investment is popular, if it takes 60 years for one cycle of investment, there will be no one who will invest in VT gold. Moreover, with the current method of afforestation, which requires additional funds for 10 years after planting, fewer and fewer people will invest in afforestation.
その状況を是正憚るためには１通常の金融投資のように
、１０〜１５年を１サイクルとする植林の仕方に変えな
ければ、植林する人はいなくなってしまう。In order to rectify this situation, we must change the way we plant trees to a cycle of 10 to 15 years, like regular financial investments, or there will be no one left to plant trees.

０年時代から、１０〜１５年時代に。In the world, there are 15
There are coniferous trees that can be felled every year, so instead of plugging, we are now in an era where it is possible to search around the world for coniferous trees that can be planted and vines that are suitable for Japan, and to create new varieties through hybridization and plant fusion. . Furthermore, through artificial photosynthesis, it is possible for the seedlings planted to grow to 3 to 4 meters in height in three years. If you plant those artificially enlarged seedlings, you no longer need additional funds after planting such as thinning and underbrush removal.As a result, the reforestation cycle will eventually become 1 cycle 6.
From the 0 year era to the 10-15 year era.
まもなく替わることであろう。It will likely be replaced soon.
ただ急成長する樹木は、ねじれ等の歪みが出やすい欠点
と、年輪が粗いので強度に問題がある欠点は存在してい
る。However, trees that grow rapidly have the disadvantage that they tend to become distorted, such as twisting, and that their annual rings are coarse, making them weak.

っている。それを解決する方法として１本発明を利用し
うる。この本発明の利用しうる過程を以丁に順次説明を
行なうことにする。As it is known that the cause of distortion such as twisting is a phenomenon that occurs during the drying process, methods of drying the log or fluctuating pressurization of saturated steam immediately after sawing can be used. The problem with changing the method of planting trees using reduced pressure from a 60-year cycle to a 5-year cycle is that the only problem left is to artificially increase the strength of the trees by 1. The present invention can be used as a method to solve this problem. The processes in which the present invention can be used will be explained in detail below.
有機化学物質の中には、加熱温度を］２０〜３００度に
して加圧すれば、化学変化を起こす物質は多数存αして
いる。Among organic chemicals, there are many substances that undergo chemical changes when heated at temperatures of 20 to 300 degrees Celsius and pressurized.
２、木材を、空気をａ体する加熱にて木Ｈを１２０〜３

熱蒸気を用いて温度を発されている。2. Heating the wood with air to a temperature of 120~3
If heated to 00 degrees, the wood will crack and warp, making it unusable.Heating steam is used as a method that does not cause cracks or warps in the wood even when heated to that temperature. The temperature is being emitted.

When increasing the temperature of the wood and causing chemical changes in the organic chemicals injected into the wood, all harmful resins in the wood are removed by varying pressure of saturated steam, regardless of the thickness of the wood. Patent No. 138.370 has developed a method for removing nitrates by causing a steam distillation phenomenon using reduced pressure.

圧注入法や真空注入方法で注入が困難であった樹木の送
局部以外でも容易に注入しうるようになる。4. It is difficult to inject chemicals into natural wood because there are extremely thin capillaries and cell cavities that are necessary for injecting chemicals into natural wood. To facilitate this, patent application No. 1-1647 describes a method for creating a new injection route by rapidly turning the large amount of water within the wood into steam and causing a small-scale steam explosion within the wood.
89 have been developed. By using this method, it becomes possible to easily inject into areas other than the local areas of the tree, which were difficult to inject using conventional pressure injection methods or vacuum injection methods.
成長の速い樹木は木材の組織が粗いから、尚容易に注入
しうる。Fast-growing trees have coarser wood structures and are easier to inject.

解されたものと思つ。6 Patent application 2-13285 has been filed for a method of drying fast-growing trees in the form of logs5, and cracks, twists, and distortions in sawn timber products occur during the process of decreasing moisture content. We know that this is a phenomenon that occurs, so if we mill logs that have been dried, this problem will not occur.With the above explanation, we can reduce the reforestation cycle to the current 60 years! 1)
-Required r to make it 15 years! I hope you understand that the 'M point only artificially enhances the ilA degree of the tree.

IIv! In addition to removing all the resin in patent 1380370, we artificially created an injection route using the method of patent 1!1-164789, which makes it difficult to inject chemicals into wood that is difficult to inject into ordinary wood. One or more types of organic substances dissolved in the solvent are injected under pressure, the volatile solvent is released, and only the chemical substances dissolved in the solvent are left inside the wood, followed by saturated steam. The internal temperature of the wood is raised to over 100 degrees using a low variable pressure, and at the same time, the humidity is maintained at an appropriate level so that the wood will not be damaged even if the entire wood is heated with steam. 4. Using the method of Special 7+1391461, the temperature of the entire wood is raised to 120-300 degrees, and the injected organic chemicals are caused to undergo chemical changes.

、業界に益する所多大である。Organic chemistry like that? When VA is left in wood and heated to an even temperature throughout the wood, it chemically changes into polymethyl and polymethyl methacrylate, turning it into plastic. Homopolymers of such vinyl monomers can also improve the strength of wood, but at the beginning of this process, the i'mw quality that can combine with the cellulose of the wood is preheated with variable pressure of saturated steam. Then, by increasing the heating temperature using variable pressurization of heated steam, the temperature can be raised without damaging the wood. After injecting into
Since this invention is characterized by emitting a volatile solvent and chemically changing the remaining organic chemicals, it can be applied to common themes such as rot prevention, insect prevention, dyeing, and fire protection, which have traditionally been difficult to inject into the entire wood. Reforestation is one of the most effective measures to prevent global warming, which is a worldwide problem.
Even the remaining strength of 1++'IN, which would allow the cycle period to be reduced by a quarter, which is not even talked about at present, can be solved by chemical changes using the method of the present invention.
The scope of application of the method of making composite wood according to the present invention is very wide, and the benefits to the industry are many.
