Abstract

PURPOSE:To obtain the gas absorbing element having high tear down strength and anti-wear property, by alternately adhering and laminating a flat and a corrugated sheet materials wherein at least one of them comprising an activated carbon fiber mixed paper impregnated with an inorg. reinforcing agent. CONSTITUTION:At least one of a flat sheet material 1 and a corrugated sheet material 2 is constituted from an activated carbon fiber mixed paper impregnated with an inorg. reinforcing agent and said sheet materials 1, 2 are alternately adhered and laminated to form a block having plural small permeation pores 3 between both end surfaces thereof to obtain a gas absorbing element. This element is enhanced in tear down strength and anti-wear property and, by uniformly holding cross areas of small permeation pores, molding and handling thereof is made easy.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gas absorption element formed by laminating and molding activated carbon fiber-containing paper from one end to the other so that a large number of small holes pass through the paper.

A planar sheet made of activated carbon fiber-containing paper and a corrugated sheet are adhesively laminated to form a one-sided corrugated body, and this is laminated or 11! The present applicant has proposed a technique for obtaining a gas absorbing element having a large number of small through-holes permeated through both end faces by stacking layers twice as shown in FIGS. 1 to S.
828).

For example, a gas element can pass air through its impermeable wall.*For example, when air is present in the gas element, it can absorb organic solvent vapor, silicon oxide, ozone, and sulfur oxidation. Although it can be used to absorb objects and obtain cleanliness, activated cardan fiber-containing paper does not have the same tear strength and abrasion resistance as the current one.
syi * Weak strength and lack of self-retention - so-called waist is 1k
In HO, a large number of small through holes are easy to form during use, resulting in an increase in air resistance. Laminated molding of shaped Ichihiro elements,
Furthermore, careful attention is required during installation and operation of the O part of the element, which improves work efficiency but has %A drawbacks.

Zero Hatsu eliminates the above-mentioned drawbacks and uses activated carpene fiber-mixed paper to create a nine-gas absorbent intermittent KS? -Wrinkle-activated fiber-containing paper improves tear strength and abrasion resistance without reducing the gas adsorption performance of paper mixed with fibers, strengthens the stiffness, and maintains a uniform cross-sectional area of the passage holes. The purpose is to prevent performance deterioration and to make molding and handling easier & 6L.1. This achievement is achieved. Embodiments will be described in detail below with reference to the drawings.

Example 1 A diameter of S to 10, a length of 1 to 8 o, an active ★-pon delicate of SO to 8 o, a pulp, a synthetic pulp, and a glass fiber and an asbestos fiber of 60 to 10. −
Activated carbon fiber-containing paper prepared by mixing paper with a binder of 6 to 1 O- is immersed in a go- silica aqueous sol and dried to adhere silica fine particles of 5 to sob based on the weight of the paper, followed by molding. [One way] Corrugated sheet material (polyvinyl acetate-based,
The planar sheet material a) is adhered using an appropriate adhesive such as Evo Life resin, and the resulting nine-wave molded body is wound and laminated around the core material (4) as shown in Figure 1. to obtain a rotary deodorizing element, and also to form a long single wave molded body into square, rectangular,
They are cut into rhombuses, parallelograms, etc., and stacked and bonded so that the direction of the waves is perpendicular to each other as shown in Fig. 2 to obtain an orthogonal L-shaped deodorizing element, or as shown in Fig. S. A parallel flow type deodorizing element is obtained by stacking and joining them in the same direction.

In this case, the planar sheet material) and the corrugated sheet material ('4
Either one of the two may be composed of a flexible sheet material other than paper mixed with activated carbon fiber, such as paper, cloth, asbestos paper, synthetic resin sheet, thin metal layer, etc. In this case, one of paper, cloth, asbestos If water-absorbing materials are used, such as paper, they may be soaked with silica sol in the same way as activated carbon-containing paper. 2
) may be made of paper or cloth to which activated carbon fine particles are attached.

Example Dew A planar sheet material (1) made of the activated carbon fiber aS paper shown in Example 1) and a corrugated seed material (14) were adhesively laminated to form a single wave molded body, which is shown below. After molding into a rotary deodorizing element, a cross-flow type deodorizing element shown in Fig. 2, and a parallel-flow type deodorizing element shown in Fig. A deodorizing element product is obtained by attaching 6 to 20 percent Al2 fine particles to the weight of the paper.

Example 11 In Example I, the size of the small through holes is pitch S
, Byam, height 1.8mm, paper thickness o, go with gll
If the unevenness of the multilayered molded product is jlomm x 20mm,
When a 40 g weight was placed on this, the control example of No II & Luck shrank by 6 mym@degrees, whereas the shrinkage of the specimen treated with the present invention stopped at just m@degrees.

In the above Example I, either the planar seed material (1) or the corrugated sheet material (2) may be made of paper, cloth, asbestos paper, metal resin sheet, metal thin layer, etc. other than paper mixed with activated carmen fibers. It may be composed of a flexible sheet material, or it may be composed of fine paper with activated carbon particles attached to it. ★You can also use an aqueous sol from Aldensu <, 1. Calcium chloride or chloride after immersion in a water glass aqueous solution! Dip in an aqueous solution of Daneshicum and dry.
Calcium silicate is 9 silicic acid! Fine particles of gnesium can also be attached.

The present invention has the above-mentioned structure.11 The inorganic reinforcing agent 9 mold particles i are attached to the paper mixed with activated cardan fibers, and there is no effect on the gas adsorption properties of the activated carbon fibers and the adhesiveness of the paper mixed with activated cardan fibers. In order to increase the tear strength, compressive strength, and abrasion resistance of the gas absorbing element obtained using the activated carbon fiber-containing paper and to strengthen the stiffness, the cross-sectional area of the path holes changes to improve the air flow. It is possible to provide it at a low price (without fear of increasing resistance, and it is easy to mold and handle), and it also has the effect of increasing heat resistance and allowing safe handling.
