Abstract
Description
【発明の詳細な説明】
この発明は活性炭で成り、通気性を持たせた多孔質構造
体に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a porous structure made of activated carbon and provided with air permeability.
従来、気体を通過させて吸着浄化する活性炭を担持した
構造体は、たとえば第１図のように連続気孔のウレタン
フオーム１の多孔表面に活性炭粒２を接着剤３で付着さ
せたものであった。Conventionally, a structure supporting activated carbon that adsorbs and purifies gas by passing through it has been made by adhering activated carbon particles 2 to the porous surface of a continuous pore urethane foam 1 with an adhesive 3, for example, as shown in Fig. 1. .
このものは基材がウレタンであるため高温ガスを通過さ

るおそれもあり、活性炭粒が接着剤１とよって被われる
部分は吸着作用をしない無効部分となってしまうという
欠点がある。Since the base material of this product is urethane, if it is used in a high-temperature atmosphere, such as by passing a high-temperature gas, or if it is used in an application that generates heat during adsorption, the structure will deform or collapse. Further, there is a risk that the activated carbon fine powder may peel off and be washed away, and there is a drawback that the portion where the activated carbon particles are covered by the adhesive 1 becomes an ineffective portion that does not have an adsorption effect.
この発明は前記のような欠点のない活性炭め多孔質構造
体およびその製造方法を１供するものである。The present invention provides an activated carbon porous structure and a method for manufacturing the same, which are free from the above-mentioned drawbacks.
すなわち炭化物のみで成る多孔質構造体を形成しその表

。To manufacture such a structure, a base material of open-pore urethane foam having a desired porosity is impregnated with a thermosetting synthetic resin such as a phenolic resin, and then heated and baked to harden the synthetic resin. At the same time, the urethane foam of the base material is burnt out, and the synthetic resin is further carbonized, yielding an integral porous structure 4 made of clay material. Next, this carbide structure is subjected to an activation step in a commonly used activated carbon manufacturing method. Then, this carbonized structure itself is provided with micropores having an adsorption effect and activated, thereby making it possible to obtain the porous structure of the present invention. By adjusting the activation process, it is possible to provide adsorption characteristics depending on the adsorbed substance.
この発明による多孔質構造体はｍ−な材料を炭化させた
一体的なものであるから活性炭粒の接着剥離等による不
具合がない。また接着剤に被われて活性炭の微細孔が無
効化することもなく、活性炭自体が多孔質構造体である
から有効な微細孔を多く持たせ吸着性能を向上させるこ
とができる。さらに空隙率が大となるから通気抵抗を減
少させることができ、炭化物のみで成るから高温ガスの
通過や発熱吸着作用にも十分耐えうるものである。Since the porous structure according to the present invention is made of an integral carbonized m-material, there are no problems such as adhesion and peeling of activated carbon particles. Further, the micropores of the activated carbon are not disabled by being covered with adhesive, and since the activated carbon itself is a porous structure, it can have many effective micropores and improve its adsorption performance. Furthermore, since the porosity is increased, ventilation resistance can be reduced, and since it is made only of carbide, it can sufficiently withstand the passage of high-temperature gas and the heat-generating adsorption action.

ることができる。Furthermore, according to the manufacturing method of the present invention, by appropriately selecting the porosity of the urethane foam of the base material and the amount of the synthetic resin to be impregnated, the porosity and amount of activated carbon of the formed structure can be changed. Depending on the application, a material with low ventilation resistance per volume or a material with high adsorption performance can be selected and manufactured.
