Description

  The present invention relates to a method for magnetizing wood. Specifically, iron and wood are immersed in an aqueous methane gas solution in a sealed container, and the liquid is vigorously stirred or vibrated to elute the iron material, which is absorbed into the wood and permeates and deposits to magnetize the wood. Regarding the method. Here, the magnetized wood refers to wood that is attracted to a permanent magnet because the wood simply absorbs the iron material.

  Conventionally, attempts to absorb iron ions, etc. into wood and reduce them to iron, or change them to iron oxide and magnetize them have the disadvantages of considerably destroying the appearance of the wood and the structure of the body. It was.

  The present invention is a method of magnetizing wood using the phenomenon that the condensed water of the natural gas transport pipe dissolves the iron pipe and that the eluted iron material is absorbed and deposited on the wood and has magnetism.

  The combustible natural gas transport pipe is often corroded if the transport pipe is made of iron when condensed water is produced due to changes in temperature and pressure in the pipe (for example, Patent Document 1). This is because an aqueous solution of natural gas based on condensed water stirs vigorously and vibrates in the gas stream, so that iron is dissolved. This is an experiment using methane gas, which is the main component of combustible natural gas, in the laboratory. I can confirm.

  That is, when water and an iron material are accommodated in an autoclave and methane gas is injected, an aqueous methane gas solution is easily generated. When the aqueous solution is vigorously stirred, the iron material is dissolved. When wood is immersed in the aqueous solution, the iron material is absorbed into the wood and penetrates and deposits. Thus, the iron material deposited on the wood has magnetism, and the whole wood is attracted to the permanent magnet.

  As described above, the present invention is a method for magnetizing wood using a phenomenon in which an iron material is dissolved in another form, not ionized, and is absorbed in the wood and deposited in a magnetic state.

  JP-A-10-217208.

The present invention is a method for magnetizing wood using the fact that iron material and wood are put together in an aqueous methane gas solution and the aqueous solution is vigorously stirred, the iron material is eluted, moves into the wood, penetrates and deposits, and this shows magnetism.
The object of the present invention is to realize a method of magnetizing without deteriorating the appearance and other characteristics of wood.

  In order to achieve the above-mentioned object, the present invention achieves the above object by immersing the iron material and wood in a methane gas aqueous solution in a sealed container, and vigorously stirring the aqueous solution to dissolve the iron material, and the wood is magnetized by utilizing the absorption of the wood. It is a method to do.

  When the aqueous methane gas solution is stirred and vibrated, the iron material will be dissolved. In the case of an autoclave, a stirring device is used. In a general sealed container, the iron agent is also dissolved by vigorously circulating or vibrating by taking out the aqueous methane gas solution and re-pressing it with an external pump.

It can be seen that the aqueous methane gas solution in which the iron material is dissolved is colorless and is not an ionic solution because the standard monopolar potential is not detected. When the solubility is measured by the evaporation to dryness method, the solubility of any iron material (commercial reagent first grade iron: Fe, iron oxide: FeO, and triiron tetroxide: Fe ₃ O ₄ ) at room temperature is short at high temperatures and high pressures. Although it dissolves quickly, it can be replaced at room temperature, normal pressure, and for a long time, and these cannot be limited.

  Although the correlation between the rotational speed of the stirrer of the autoclave and the solubility of the iron material is not obtained, as an example, when the rotational speed was 200 rpm, the solubility of any iron material was 100 to 150 ppm.

  In the test using an argon gas, which is an inert gas instead of methane gas, as a blank test, no dissolution of the iron material was observed. Therefore, it seems that the aqueous methane gas solution dissolves iron material in a special form.

  It was confirmed that the iron material dissolved in the methane gas aqueous solution was well absorbed by wood. The timber used was cedar, birch, white birch, birch, cocoon, etc., but it seems that it is generally absorbed by timber composed of lignin and cellulose.

  The shape of the wood can be used for any shape such as long logs, plates, and large sawdust. When the iron material dissolved in the aqueous solution is absorbed by the wood, it immediately deposits inside the wood. The iron material in this state has magnetism like the raw material iron material, and the whole wood is attracted to the magnet.

Although the form of the iron material dissolved in the aqueous methane gas solution of the present invention and the iron material deposited on the wood is not detailed, it can be seen that when the magnetized wood is burned, it is absorbed to the deep part of the wood. The iron material after combustion becomes ferric oxide: Fe ₂ O ₃ and the magnetism disappears.

  As described above, the present invention is a method for magnetizing wood using a phenomenon in which an iron material dissolved in an aqueous methane gas solution automatically permeates and deposits in wood as if an object falls.

  Thus, the wood that has absorbed the iron material seems to have accumulated the iron material in the wood part, and it does not suffer any obstacles on the surface, it has magnetism but does not lose its original properties as a wood, it simply becomes a magnet It was attracted and exhibited the effect of being magnetized as intended.

  The present invention is a method for magnetizing wood using the fact that an iron material dissolved in a methane gas aqueous solution moves and deposits while the wood has magnetism. It is the best mode to assemble the apparatus so that the elution of the iron material, movement in the solution, and deposition in the wood can be easily performed.

  An airtight container is used to store iron materials and wood logs or molded products for the purpose of magnetizing, and a sufficient amount of water to immerse them is put in. The air in the upper space is replaced with methane gas so that methane gas can be injected. . Stir the internal water or allow the liquid to circulate or vibrate with an external pump. An external heating method is convenient for the heating method.

In order to operate the present invention efficiently, when using a device for dissolving an iron material in a sealed container 1 and infiltrating and depositing the iron material in wood with a sealed container 2 and circulating an aqueous solution between the container 1 and the container 2 Both the container 1 and the container 2 must be able to enclose methane gas.
The following examples illustrate but do not limit the invention.

In a 500 ml autoclave made of SUS316, 5 g of iron (commercial reagent first grade iron: Fe powder) and 250 ml of water were taken, and a piece of wood (white birch) of 5 × 5 × 20 mm was put and sealed.
The internal air was replaced with methane gas, and the pressure was continuously pressed to set the internal pressure to 5 MPa (gauge pressure). The rotation speed of the agitator of the autoclave was 200 rpm, the temperature was 100 ° C., and the mixture was held for 2 hours. The wood was cooled to room temperature, taken out, washed with water and dried. This wood was attracted by a permanent magnet.

  The present invention provides magnetically treated wood, and it is easy to embed a signal in the wood and can be used for a communication business, a transportation business of goods, and the like.

  When the large sawdust or the like magnetized according to the present invention is burned, the wood obtains a catalytic action of the iron material and burns completely, so that it becomes a low temperature fuel material.

  By applying the method of the present invention, it is possible to provide foreign wood by absorbing materials other than iron materials into the wood.

  The methane gas used in the present invention is very advantageous because it only uses its physical properties and retains its chemical properties as a fuel and raw material.
