Description

  The present invention relates to a paperboard containing charcoal fine powder and a method for producing the paperboard.

Rust tends to occur on metal blades, and even with a stainless steel knife, part of the blade may be discolored. As a method for removing such rust and discoloration, for example, the blade is polished with a detergent containing an abrasive.
However, the operation of polishing the blade with a detergent containing an abrasive is complicated.
Further, as a method for removing rust and discolored portions, it is possible to polish the blade with abrasive paper. The abrasive paper is obtained by fixing abrasive grains made of aluminum oxide or the like with an adhesive on the surface of a base material made of paper, for example.

However, in ordinary households, it is rare to use abrasive paper to polish the knife blade. This is considered to be due to the absence of suitable abrasive paper when considering the safety of the material when polishing a knife used to cut food.
On the other hand, Japanese paper containing bamboo charcoal fine powder is known as a Japanese paper for packaging, although it is not abrasive paper (see Patent Document 1). This Japanese paper is said to have a deodorizing action and adsorption performance due to bamboo charcoal fine powder interspersed between fibers.
JP 2005-307385 A

In consideration of the safety of the material, the present inventor has conceived to polish the blade of a knife using a paper with fine charcoal powder as polishing paper.
However, as described in Patent Document 1, even if charcoal fine powder is mixed in an aqueous solution made of dredged fiber paper material, velvet and water in a tugboat, the charcoal fine powder floats and is washed away. It leaks when whispering. For this reason, the obtained paper does not contain any fine charcoal powder and is not suitable for polishing blades.

  The present invention has been made based on the above-described circumstances, and an object of the present invention is to provide a paperboard containing fine charcoal powder sufficiently containing charcoal fine powder and a method for producing the paperboard.

In order to achieve the above-mentioned object, the paper is filled with charcoal fine powder comprising firewood fibers and charcoal fine powder adhering to the fibers, the charcoal fine powder together with the straw skin in an alkaline aqueous solution. A paperboard containing fine charcoal powder is provided, which is attached to the fiber by boiling (Claim 1).
Preferably, it is used to polish a metal blade, and the paper with fine charcoal powder according to claim 1 (claim 2).

  Moreover, according to the present invention, there is provided a method for producing a straw paper containing fine charcoal powder, comprising a boiling step of boiling firewood skin and fine charcoal powder in an alkaline aqueous solution (claim 3). .

According to the first aspect of the present invention, the fine charcoal powder containing charcoal is adhered to the fiber by boiling it with the straw peel in an alkaline aqueous solution, so that the texture of the fine paper is maintained. While containing a sufficient amount of charcoal fine powder.
Further, the paper with fine charcoal powder is safe because synthetic glue is not used for adhering the fine powder.

For this reason, this paper with fine charcoal powder is suitable for polishing the blade of a metal knife (claim 2).
According to the method for producing the paper with fine charcoal powder of claim 3, the fine powder of charcoal adheres to the fibers of the firewood by boiling the straw skin and the fine powder of charcoal in an alkaline aqueous solution. A fine paper containing fine powder of charcoal containing a small amount of fine powder of charcoal is produced.

Hereinafter, paper with fine charcoal powder according to an embodiment of the present invention will be described.
As shown in FIG. 1, the charcoal containing fine charcoal powder is composed of firewood fibers 10 and fine charcoal powder 12 adhered to the firewood fibers 10. Since the fine paper containing the charcoal fine powder adheres to the fine fiber 10 in a state where the fine powder 12 of the charcoal is uniformly dispersed, it exhibits a black color while maintaining the texture of the fine paper.
And this paper containing fine charcoal powder contains fine powder 12 of charcoal, so it has antibacterial properties, polishing properties, deodorizing properties, degreasing properties, and decolorizing properties, such as rust generated on the blade of a metal knife. Suitable for removing discoloration.

The charcoal fine powder 12 is preferably a fine powder of Bincho charcoal, and preferably has a particle size of 500 mesh to 800 mesh. Further, the paper with fine charcoal powder preferably contains 400 g or more and 800 g or less of charcoal fine powder 12 with respect to 100 g of firewood fibers 10.
This paper with fine charcoal powder is produced as follows.

As shown in FIG. 2, first, boiled skin (white skin) as raw material and charcoal fine powder are boiled while being mixed in an alkaline aqueous solution (boiling step S10). The cocoon skin is obtained by removing the black skin and the cuticle layer from the bast of the cocoon.
In the boiling step S10, the temperature of the alkaline aqueous solution is set, for example, in a range of 60 ° C. or more and 120 ° C. or less, and the straw and charcoal fine powder is boiled while being stirred, for example, for 2 hours or more and 5 hours or less.

As the alkaline aqueous solution, for example, an aqueous solution containing potassium carbonate, calcium oxide (lime), sodium carbonate (soda ash) or sodium hydroxide (caustic soda) as a solute can be used, and sodium carbonate can be used as a preferable solute. .
The mass of the alkaline aqueous solution used for boiling is, for example, not less than 8 times and not more than 10 times the mass of salmon skin, and the mass of the solute used for boiling is, for example, 12% or more of the mass of boiling salmon skin. 15% or less.

After this boiling step S10, the cocoon skin is taken out from the alkaline aqueous solution and, if necessary, unwanted dust contained in the washed cocoon skin is removed. Thereafter, the skin of the cocoon is struck and loosened to obtain cocoon fibers (striking step S12).
Then, the obtained cocoon fibers and a sticky agent (batter) are added to water and mixed, and a layered product made of cocoon fibers is obtained by pouring or pooling from the obtained aqueous solution (sowing step S14).

The layered product is subjected to a dehydrator and then dried (drying step S16), whereby a paper with fine charcoal powder is produced.
According to the manufacturing method described above, in the boiling step S10, the fine powder 12 of charcoal adheres to the fiber 10 of the firewood in a uniformly dispersed state. This is because, in the boiling step S10, a paste-like substance is generated in the alkaline aqueous solution, and the charcoal fine powder 12 adheres to the firewood fibers 10 through the paste-like substance.

In the firing step S14, the charcoal fine powder 12 has already adhered to the firewood fibers 10, so that the charcoal fine powder 12 does not float, and a sufficient amount of the charcoal fine powder 12 is uniformly formed. It can be included in the paper in a dispersed state.
Moreover, since the charcoal fine powder 12 is made to adhere to the fiber 10 in the boiling step S10, it is possible to manufacture a paperboard containing the charcoal fine powder without requiring addition of a new process.

The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, the adhesive may be a synthetic paste, but in consideration of the safety of the material, it is preferable that the adhesive is a natural adhesive extracted from trolley mushrooms or sorghum.
Further, the use of the fine paper containing fine charcoal powder is not limited to the polishing of the blade of the blade, and can be used for, for example, shoji paper.

It is a perspective view which shows the charcoal containing the charcoal fine powder powder which concerns on one Embodiment of this invention, and the inside of a circle is the schematic which expands and shows a part of the said corrugated paper. It is process drawing for demonstrating the manufacturing method of the paperboard containing the charcoal fine powder of FIG.
