Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a deodorizing element obtained by bonding and laminating a flat sheet material and a corrugated sheet material.

A planar sheet material 1 made of activated carbon fiber-containing paper and a corrugated sheet material 2 are adhesively laminated as shown in FIG. 1 to form a single-wave molded body 4, and the single-wave molded body 4 is formed as shown in FIG. The inventor of the present invention disclosed in Japanese Patent Application No. 54-92817 (Japanese Unexamined Patent Publication No. 54-92817) a rotary deodorizing element having a cylindrical shape formed by winding and laminating around a core 5a and having a large number of small through holes 3 through both end faces. This was disclosed in No. 15828 (Sho 56-15828).

Such a deodorizing element, for example, adsorbs harmful gases contained in the air, such as organic solvent vapor, nitrogen oxides, ozone, sulfur oxides, etc., by passing air through its small holes 3 to obtain clean air. However, when used, for example, to adsorb and decompose ozone generated in an electrostatic transfer type copying machine, a deodorizing element having a special shape different from a cylindrical shape as shown in FIG. 3 is required. In molding such a specially shaped deodorizing element, a thin plate-shaped core 5b is used in place of the cylindrical core 5a shown in FIG. When molding the single wave molded body 4, the activated carbon fiber-containing paper currently lacks sufficient shape retention, and even if the winding and laminating work is performed with care, the paper near both ends of the core 5b In Nos. 6 and 6, the shape of the single-wave molded body 4 was destroyed, and the cross-sectional area of the small through holes was significantly narrowed, resulting in a decrease in deodorizing efficiency.

The present invention eliminates the above-mentioned drawbacks, and an embodiment will be described below with reference to the drawings.
30-80%, pulp, synthetic pulp, and or glass fiber 60-10%, size 5-10%
Activated carbon fiber made into paper with a thickness of about 0.1 to 0.5 mm〓〓〓〓
A planar sheet material 1 made of fiber-containing paper and a corrugated sheet material 2 are made into a long single-wave molded body 4 with a width of 20 mm, with a large number of small holes 3 passing through both side edges as shown in FIG. As shown in Fig. 4, it is wound around the outer circumference of a cylindrical core 5 with a diameter of about 100 mm, and after winding it to the required thickness of 40 mm, the core 5 is pulled out and the hollow part is crushed to form the desired shape as shown in Fig. 5. A deodorizing element is obtained by molding and having small through holes through which processing gas passes over the entire surface of both end faces. The dimension of this element is long diameter 250
mm, and the short axis is about 80 mm.

In this case, a flat sheet material 1 and a corrugated sheet material 2
Other sheet materials such as paper, a sheet of fiber composite material such as cloth, asbestos paper, a sheet of synthetic resin, a thin metal plate, etc. may be used for either one of the two. In addition to the cylindrical shape, the core 5 may be a cylindrical body having any end face shape without round edges.

Since the present invention has the above-mentioned configuration, there is no fear that the wave shape of the single-wave formed body will collapse even at the inner edge portions 6, 6 of the wound single-wave formed body, and carbon fiber-containing paper with poor shape retention can be used. Even when used, it has the effect that a deodorizing element having small through holes 3 with a uniform cross-sectional shape can be obtained reliably, easily and quickly.

Claims (1)

[Claims] 1 At least one of the planar sheet material 1 and the corrugated sheet material 2 is made of activated carbon fiber-containing paper, and both sheet materials are bonded together to form a long single wave with a large number of small holes 3 passing through both sides. The single-wave molded body 4 is wound around the outer periphery of a core 5 having a smooth peripheral ring, and the core 5 is removed and the hollow part of the wound single-wave molded body 4 is crushed to form the desired shape. A method for producing a deodorizing element, characterized in that the element is formed into a shape and configured so that a processing gas passes over the entire surface of both end faces of the element.
