無臭化する方法では、あらゆる悪臭成分に対して有効な
触媒は未だ知られておらず、特定の悪臭成分しか発生し
ない場所の他は利用できない。"Prior art and its problems" Countermeasures against bad odors include a method of eliminating the bad odor visually using an aromatic agent, a method of making the malodorous component odorless by decomposing it with a catalyst, and a method of adsorbing and removing the malodorous component with an adsorbent. There is a way to do it. Among these methods, in the method using an aromatic agent, the aromatic agent must emit a stronger aroma than the malodorous component, and the strong aroma may actually cause discomfort. In addition, a catalyst decomposes malodorous components,
In the method of deodorization, a catalyst that is effective against all malodorous components is not yet known, and it cannot be used except in places where only specific malodorous components are generated.
吸着作用を有する脱臭剤としては、従来、一般に活性炭

う問題点があった。Activated carbon has conventionally been generally used as a deodorizing agent having an adsorption effect. Activated carbon can adsorb and remove quite a lot of malodorous components, but it cannot effectively adsorb and remove basic gases such as ammonia, and activated carbon burns at high temperatures, so it cannot be used in places exposed to high temperatures. There was a problem.
したがって、あらゆる悪臭成分に対して存効であり、使
用可能温度条件に制限がない脱臭剤の開発が求められて
いる。Therefore, there is a need for the development of a deodorizer that is effective against all malodorous components and has no restrictions on the temperature conditions under which it can be used.

Various materials can be used as long as the a/P ratio is 1.0 to 2.0, but considering the sinterability and strength of the granules, it is recommended that the a/P ratio be 1.5 to 1.67. preferable. Specifically, various apatites such as hydroxyapatite and fluoroapatite, tricalcium phosphate, tetracalcium phosphate, etc. can be used. These compounds can be produced by methods known per se, and can be used alone or as a mixture.

る。その他、使用する通気性材料の性質や担持方法に応
じて粉末又は顆粒の粒径を適宜選択することができる。When a calcium phosphate compound is used in the form of powder, granules, or porous granules, it is preferably supported on a sheet-like material such as paper, nonwoven fabric, mesh material, etc. to form a sheet-like deodorizing agent. Examples of methods for supporting the sheet material include a method of manufacturing paper or nonwoven fabric using calcium phosphate compound powder as a filler, and a method of impregnating a slurry of calcium phosphate compound powder. When manufacturing paper using papermaking technology using calcium phosphate powder as filler,
It is preferable to use a powder consisting of secondary particles with a particle size of 0.1 to 30 μm. If the particle size is smaller than 0.1 μm, it will fall down with water from the paper machine screen during paper making, and particles with a diameter of 30 μm
If it exceeds , it will be too heavy and it will be difficult to disperse it uniformly. In addition, the particle size of the powder or granules can be appropriately selected depending on the properties of the breathable material used and the supporting method.

抗が高くなり、不都合であり、また１０薗を超えると、
空気との接触面積が小さくなり、脱臭効率が低下する。When using granules supported on a sheet-like body as described above, it is generally preferable to use granules having an average particle size of 1 to 2000 μm. Granules with a particle size smaller than 1 μm are difficult to support on a sheet-like body, and particles with a particle size larger than 2000 μm reduce the contact area with air and reduce deodorizing efficiency. Further, when granules (including porous granules) are used by filling a container, the particle size is preferably 200 μm to 10 mm. If the particle size is too small, the air passage resistance will be high, which is inconvenient, and if the particle size exceeds 10 mm,
The area of contact with air becomes smaller, reducing deodorizing efficiency.

あってよい。In addition, the granular deodorizer only needs to have a calcium phosphate compound on at least the surface of the granules, and
Various types of granules, such as granules made of more than one type of calcium phosphate compound, granules with a core made of a ceramic material other than calcium phosphate compounds coated with a calcium phosphate compound, and granules with a calcium phosphate compound coated on the surface of an inert carrier particle. It may be an aspect.

、顆粒又はブロック体自体の強度を保持できなくなる。Furthermore, when the calcium phosphate compound is used in the form of porous granules or porous blocks, the porosity thereof is 5 to 75%. If the porosity is less than 5%, the surface area will be small (and the deodorizing effect will be insufficient), and if it exceeds 75%, the granules or blocks themselves will not be able to maintain their strength.

More preferably, it has a specific surface area of rrf/g. If the specific surface area is less than 0.1 rrf/g, the deodorizing effect will be insufficient, and if it exceeds 100 rW/g, the strength as a block will become weak.

ことによって１周整することができる。Porous granules and porous blocks of a calcium phosphate compound can be produced by various methods using crystal particles of a calcium phosphate compound wet-synthesized by a known method as a raw material. For example, a slurry in which raw material particles are suspended is directly granulated into secondary particles by spray drying, or additives such as a viscosity modifier and organic compound particles or fibers that disappear upon heating are added to this slurry and then spray dried. It is granulated into secondary particles by methods such as. These secondary particles are suspended in a slurry again and wet-molded, or formed into a block by dry-molding using pressure. At this time, an organic compound may be added to form pores by dissipating during the firing process. Even without additives, the pore size can be controlled by adjusting other conditions such as the firing temperature. The obtained block body is fired in a temperature range of 500°C to 1300°C. If the firing temperature is less than 500°C, heat loss of the organic compound and sintering of the block body will not be sufficiently performed. Furthermore, if firing is performed at a high temperature exceeding 1300°C, there is a risk that the sintered body will become too dense or that calcium phosphate will decompose. After the block body thus fired is crushed, it can be classified to obtain granules of a required particle size. The pore size of the granules can be adjusted by appropriately adjusting the size of crystal particles in the raw material slurry for secondary particle granulation, the viscosity of the slurry, additives, etc.

できる。Table 2 "Effects of the Invention" The deodorizing agent according to the present invention exhibits a deodorizing effect in a wide temperature range from low to high temperatures, and can be used in a wide range of applications. It is also effective against gases that cannot be adsorbed and removed by activated carbon, such as ammonia, and in this respect, it can be used in a wide range of applications. Furthermore, the deodorizing agent of the present invention is aesthetically pleasing because its main component, calcium phosphate, is white. For example, when it is in the form of paper, it can be used as a paper with high product value, such as white paper, colored paper, or patterned paper. It can be done.
