Abstract

PROBLEM TO BE SOLVED: To enable charcoal to be sent and placed by pneumatic transportation in a state keeping the characteristic performance of charcoal so that it is well used as a moisture conditioner or a deodorant for under ground/a wall, a soil conditioner for a plastic green house/a field/a lawn, or the like. SOLUTION: Charcoal powder mixed with a shape retaining agent is pelletized. The charcoal powder to be used has an average particle size of 0.1-1.0 mm.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an environmental conditioner (for example, a humidity conditioner, a soil conditioner, an antistatic agent, an electromagnetic wave inhibitor, etc.) using charcoal.

[0002]

2. Description of the Related Art Conventionally, charcoal has been widely used for the purpose of soil improvement and humidity control. However, the handling is difficult because the charcoal is used as it is, so that the hands and the surrounding environment are easily polluted, and the charcoal is often broken or the powder is scattered during use. Therefore, when laying charcoal under the floor as a humidifier, charcoal is packed in a bag and used, but this must be laid before the floor is put up, and bagged ones However, if the charcoal is kept in a large shape, there is a space between the bags, and there is a drawback that it is not possible to lay every corner. Furthermore, there is a danger that when the product is put into the space of the wall, the space is widened and the bagged product does not function properly due to its own weight. On the other hand, it is also known to sprinkle charcoal powder together with insecticides and herbicides as a soil conditioner, but this method stains hands and also scatters around, making it difficult to evenly sprinkle, making it practical. There was a problem with sex.

[0003]

An object of the present invention is to make it possible to use such charcoal more efficiently and effectively.

[0004]

According to the present invention, the above-mentioned problems have been solved by pelletizing charcoal while maintaining the performance peculiar to charcoal, and making it possible to blow the charcoal.

That is, in the present invention, charcoal powder is mixed with a shape-retaining agent and pelletized, but the charcoal powder retains the function peculiar to charcoal as it is and, after pelletizing, retains this function. As a result of various investigations, the average particle size of the charcoal powder is 0.1 to 1.0 mm.
And charcoal powder and a shape-retaining agent of 9
The above problem can be solved by mixing and pelletizing at a weight ratio of 9: 1 to 80:20.

The pellets may be produced by simple extrusion, but are preferably produced by pressure molding. In addition, the size of the pellets is preferably about 0.5 to 4 cm in average size so that the pellets can be constructed by air blowing or the like. It is preferable to use at least one selected from the group consisting of a bentonite and an adhesive (for example, a resin emulsion of vinyl acetate or acrylic resin).

[0007] As described above, the carbon powder used for the pellets has an average particle size of 0.1 to 1.0 mm. This is because they cannot exhibit functions such as hygroscopicity and air inhalation, and form a hard lump without air permeability. Conversely, if the particle size exceeds 1.0 mm, it is difficult to solidify and obtain practical pellets. Usually average particle size
0.1 to 1.0 mm (preferably 0.3 to 0.8 mm)
0% by weight or more, especially 70% by weight or more has a particle size of 0.1 to 1.0 mm
Is desirably included.

[0008] The charcoal powder is preferably contained in the pellets in an amount of 80% by weight or more, particularly preferably 95 to 85% by weight. In addition, additives such as metal oxides or hydroxides, antibacterial agents, insecticides, and herbicides may be mixed with the shape retention agents such as clays and adhesives used in mixture with the charcoal powder. These may be used alone or in combination of two or more.

The pellets of the present invention have the inherent hygroscopicity of charcoal, the function of preventing static electricity or electromagnetic waves, the function of improving soil quality, and the like, and can be used stably by air blowing.

Therefore, without removing the floorboard under the floor of the building, for example, the pellets can be uniformly arranged by air blowing directly from the ventilation hole or the like under the floor to function as a humidity control agent for the house. it can. In addition, in the case of ceilings, closets, clog boxes, etc., the pellets are packed in a breathable bag and used, so that the pellets can be spread without gaps according to the place where the pellets are placed. A good humidity control effect can be obtained.

In the present invention, the same applies to the case where the pellets are used as a soil conditioner, and the pellets can be easily and reliably charged to a required portion by blowing air. For example, even inside a greenhouse, without polluting the surrounding environment,
Certainly, the soil conditioner mainly composed of charcoal can be made to function. It should be noted that there is a remarkable effect of charcoal as a soil conditioner, and it has been found that the effect is increased by adding an insecticide or a herbicide.

[0012]

Next, the present invention will be described based on examples, but the present invention is not limited to these examples. The following examples were performed using charcoal having the following particle size distribution. Screen sieve (mm): 4.75 2.36 1.18 0.6 0.3 0.15 0.075 <0.075 Charcoal (%): 0.0 0.4 12.9 31.0 13.2 8.8 6.1 27.6. (Σ%): 0.0 0.4 13.3 44.3 57.5 66.3 72.4 100.0

[0013] The charcoal, bentonite and water are (1) mixed at a weight ratio of 90:10:10, and (2)
What was mixed at a ratio of 90:10:15 by weight,
A tablet test was performed with a tablet tester having a cylinder diameter of 25 mm. Table 1 shows the results.

EFFECTS OF THE INVENTION The pellets of the present invention can be blown, using charcoal as a main component, under the floor or wall as a humidity control or deodorant, or as a soil improving agent for house cultivation, or in fields such as fields and lawns. It is very easy to handle. For example, even under the floor of a house, without dismantling the floor,
By just feeding the wind pipe, the hands can be kept clean, and it is possible to lay every corner very economically and with good workability. A pocket may be formed in the wall, and air may be blown into the pocket. Further, it is possible to pack the pellets in a bag having good air permeability and lay them on a ceiling, a closet, a clog box, or the like without any gap according to the shape. As a soil conditioner, an insecticide or a herbicide can be sprayed uniformly in a state of being mixed with granular charcoal, so that it can be handled stably without contamination. Further, since it is mainly composed of charcoal, it is very useful as an antistatic agent and an electromagnetic wave preventing agent.
