下させる問題点がある。2. Description of the Related Art A large amount of pulp sludge is discharged from a paper manufacturing process. In particular, the amount of pulp sludge tends to further increase due to the increase in white calcium carbonate, kaolin, and other additives for making white computer paper with the computerization of offices. A long time ago, pulp sludge was discarded in the bays of Tago-no-Ura, etc., but it became a sludge that gave off a bad odor and became a problem as a representative of environmental destruction. Therefore, a huge hole was dug and dumped, or it was burned at 800 [℃] to 1000 [℃] and dumped in the landfill, but it cost 3500 yen per ton and the dumping place was full. As one of the solutions, it has been used as a degassing material and an antioxidant when iron is melted. However,
Due to the limitation of these treatment means, recently, a prototype is being produced in which pulp sludge is added to cement and used as an interlocking block for sidewalks. However, this product has problems such as uneven color and unburned carbon contained in the pulp sludge floating on the surface to deteriorate the appearance quality.

しなければならない重要なテーマである。As described above, the amount of pulp sludge tends to increase, and this effective treatment means has a use as a panel material in the field of construction. However, in that case, it is necessary to solve the following problems. That is,
The components of pulp sludge discarded from paper mills differ, but any pulp sludge can be used. Moisture content of pulp sludge is 60 to 70
It is difficult to control the water content because it is as large as [%], but this should be solved. To solve the drawback that the pulp sludge contains unburned carbon and remarkably impairs the designability as a building material. Further, it is necessary to satisfy the conditions such as being applicable to a product having a sufficient usage amount capable of deodorizing and treating and digesting a large amount of discharged pulp sludge. Furthermore, when it is used as a building material, it must have sufficient strength and not have a large change in length like JIS wood wool cement board. After all, the treatment of pulp sludge is an important theme that must be tackled and solved not only as an economic burden but also as a solution to the global environment.

A high ratio which is formed by mixing and kneading and kneading and, if necessary, adding a mixture of one or more selected from fly ash, sand, and an adsorbed odor material by press molding, curing and drying. It constitutes the strength panel. More specifically, it is composed of a steel plate having a large number of protrusions and is integrally formed by press molding,
The adsorbed odor material features a high specific strength panel made of zeolite and / or sepiolite and / or activated carbon.
In addition, as a method for producing this high specific strength panel, 100 parts by weight of cement, 40 ± 10 parts by weight of pulp sludge and 60 ± 10 parts by weight of water are mixed and kneaded, and the mixture is added as necessary. The mixed material is controlled in an effective horizontal direction by bending the mixture of the fibers contained in the sludge by the projections planted on the steel plate, further integrated with the steel plate and placed in the form, pressed by a press to remove moisture. It is formed into a predetermined panel shape while squeezing out, characterized by steam curing or warm water immersion curing, demolding, high speed or natural drying,
Further, the invention is characterized in that a metal plate having a large number of protrusions is laid in the mold, and the mixture is pressed against the metal plate to form an integral structure.

来る。[Function] Since pulp sludge is mixed and kneaded with cement and water, it is possible to mix and use those having different components. Further, since the carbon is sufficiently kneaded, the surface protrusion of carbon and color unevenness are reduced, and the appearance quality is improved.
Further, the water-cement ratio is reduced by the dehydrating action of expelling water in the longitudinal direction of the fiber, and the water is sufficiently removed because the water-cement ratio is cast into the mold and press-molded. Further, although the fibers of pulp sludge are short, the fibers are horizontally oriented by mixing with cement to exert sufficient bending strength, and unlike the wood wool cement board, the amount of expansion and contraction of the fibers is small, so that no deformation occurs. On the other hand, by impregnating the mixture into a steel plate having protrusions, the two are integrated, the fibers are entangled in the protrusions, and the fibers are oriented in the horizontal direction, so that the high specific strength can be further improved.

期的効果を奏するものである。According to the present invention, the following remarkable effects are obtained. 1) Fibers of pulp sludge exert a reinforcing effect, excess water is removed by press working, and pressure molding is performed, so that it is possible to greatly improve high specific strength compared with conventional cement panels. Can be done. 2) Cement, pulp sludge, water and, if necessary, mixed materials such as sand and sepiolite are mixed and kneaded to form a mixture, which is press-molded. Therefore, there is no particular problem even if pulp sludge with different components is used together. In addition, as described above, since the water is removed by the press, it is easy to manage the water content. Further, by mixing and kneading, the appearance quality is improved without color unevenness or carbon protrusion. 3) By mixing fly ash, sand and odor-absorbing zeolite or sepiolite, the quality is made uniform and the deodorizing effect is enhanced. 4) By combining a mixture of cement, pulp sludge, water, etc. with a steel plate having a large number of hook-shaped projections by pressing, the hook-shaped projections and the fibers are entangled with each other, and the strength of the steel sheet is added, resulting in an extremely high specific strength. It is possible to manufacture a panel having 5) By removing water, it is made lighter than conventional products. 6) The high specific strength panel of the present invention is used in a wide range of fields such as various formworks in the construction field, outer wall panels of houses, walls and floors of freezers, floors of condominiums, etc., thus increasing the amount of pulp sludge to be discarded. However, it can be fully covered. In particular, it has an epoch-making effect in the economic sense and in the sense of preventing environmental pollution.
