2. Description of the Related Art As is well known, a large amount of mussels adhere to seawater intake facilities such as power plants, and the large numbers of mussels removed during cleaning of the facilities are prohibited from being dumped into the ocean. Landfilled as industrial waste.

[0003]

[Problems to be Solved by the Invention] In the recent landfill disposal of a large amount of mussels, which are generated as industrial waste, it is very difficult to secure a stable landfill site due to the limited land area and location. Therefore, there is a need in the industry, especially in the power plant industry, for a means of effectively utilizing a large amount of blue mussels without final disposal by landfill.

As a method for effectively utilizing a large amount of mussels, there is known a method of incinerating and using shell ash as a neutralizing agent, but there are problems in location environment and cost of the incinerator, and Although attempts have been made to pulverize it and use it as a raw material for cement, it has not yet been put to practical use.

In view of the above situation, the present inventor has made many studies for many years with the technical task of providing a new technical means capable of effectively utilizing a large amount of mussels, but in the process, When the crushed material obtained by crushing the shells of mussels into specific-sized pieces is uniformly mixed with cement or a solidifying material composed of epoxy resin or polyester resin at a specific ratio, the appearance and strength are excellent. We have achieved remarkable technical knowledge that various molded products can be manufactured and achieved the technical problem. As far as the present inventor knows, a molded product using a mussel shell has not been proposed yet.

[0006]

The above technical problems can be achieved by the present invention I and II as follows. That is, the present invention I is characterized in that 30 to 80% by weight of a crushed product obtained by crushing a shell of a mussel to a fine piece having a size of 1 to 50 mm ² is formed into a required shape by using cement as a solidifying material. It is a molded product.

Further, the present invention II is a crushed product 20 to 8 obtained by crushing a shell of a mussel to a size of 1 to 50 mm ^2.
0% by weight is a molded product characterized by being molded into a required shape using an epoxy resin or a polyester resin as a solidifying material.

The structure of the present inventions I and II will be described in more detail as follows. First, a crushed product obtained by crushing a shell of a mussel, which is commonly used in the present inventions I and II, into small pieces having a size of 1 to 50 mm ² (hereinafter, may be simply referred to as “crushed mussel”). ) Is obtained by the following method. That is, a large amount of blue mussels collected during the cleaning work of seawater intake facilities such as power plants are crushed according to the usual method, and shell meat and foreign matter (sand, seaweed, etc.) are crushed from the crushed products.
After being separated / removed, it is obtained by classifying using a vibrating sieve or the like, collecting fine pieces of a required size (1 to 50 mm ² ) and washing / dewatering.

[0009] The dimensions of Murasakii shellfish crushed product obtained by the above method is important, in the case of 1 mm ² or less is not unique feeling can be obtained with the shells will exhibit the same appearance and sand, 50 mm ² In the above cases, molding is difficult. The most preferred size range is 4-10 mm ² . It should be noted that in use, those having substantially the same size may be collected and used, and those having a large size and a small size may be used.

Next, in the present invention I, the crushed mussels are molded into a required shape by using cement as a solidifying material.

Commercially available portland cement or white portland cement may be used as the cement that serves as a solidifying material.

The blending ratio of the crushed mussels of the present invention I is important, and when it is less than 30% by weight, it is difficult to obtain a molded product having a beautiful appearance and excellent strength.
When the content is more than 10% by weight, it is difficult to obtain practically satisfactory strength. A preferred blending ratio is 50 to 75% by weight. When 30% by weight or more of the crushed mussels are mixed, fine aggregate (eg, stone powder, mountain sand, crushed sand) or coarse aggregate (eg, aggregate) that is commonly used as an aggregate for cement molded products
Granite, Oshima black, crushed stone, limestone, etc.) can be used in combination, but the blending ratio must be 80% by weight or less in total with the crushed mussel crushed products. In the case of the above, it is difficult to obtain practically satisfactory strength. In addition, an appropriate amount of pigment can be added for coloring according to a conventional method.

The method for producing a molded article according to the present invention I is no different from the method usually employed in the production of a cement molded article, and the crushed mussels, cement and water are

After demolding and curing for a required period, the surface is polished and finished, whereby a molded product having a beautiful appearance in which shell fragments are exposed on the surface and having excellent strength can be obtained. When preparing the mixture, it is preferable to add a commercially available admixture (for example, Beam W Gold: trade name: Fuji Fine Chemical Co., Ltd.) according to a conventional method.

In the most preferred embodiment of the present invention I, the molded product is a terrazo (Pr) of JIS A 5411-1994 standard.
ecast terrzo). When the present invention I is carried out in the form of a terrazo block or a terrazotile, it is possible to obtain a product comparable to a known marble terrazzo block or a marble terrazzo tile.

Next, in the present invention II, the crushed pearl oyster shells are molded into a required shape using an epoxy resin or a polyester resin as a solidifying material.

Commercially available products may be used as the above resins, and examples of the epoxy resin include ADEKA EP-42.
0 (trade name: Asahi Denka Kogyo Co., Ltd.) is suitable, and examples of the polyester resin include Polylite TP-1.
56, TP-254, TP-123 (all are trade names: Dainippon Ink and Co., Ltd.) and Epolak MR-30

You may add a pigment and may color it.

The mixing ratio of the crushed pearl oyster shell of the present invention II is important. When it is 20% by weight or less, it is difficult to obtain a molded product having a beautiful appearance, and when it is 80% by weight or more, it is practically used. It is difficult to obtain satisfactory strength. The most preferable blending ratio is 50 to 70% by weight.

The method for producing a molded product according to the present invention II is no different from the method usually employed in the production of a synthetic resin molded product, and the required method selected from the crushed pearl oyster shell and each of the above synthetic resins is used. Weigh the required amount of resin and knead it well using a well-known mixer, etc. to make a uniform mixture, pour this into a mold of the required shape and mold it, and select the curing conditions specific to the required resin. After being cured according to the procedure described above, the molded product can be obtained by removing from the mold and having a beautiful appearance in which shell flakes are exposed. After the mold is removed, the surface is buffed to give a more beautiful appearance.

Further, a molded product having an appearance similar to that described above can be obtained by applying the mixture to the surface of a synthetic resin molded product in a required thickness and curing it. In addition,
It is desirable to apply the above mixture when the synthetic resin molded product to be coated is in an uncured state, and to completely cure the synthetic resin molded product and the coating layer at the same time.

[0020]

First, the operation common to the present inventions I and II is that the shell of the mussels is very thin with a thickness of about 0.7 mm, and it is made into strips with a size of 1 to 50 mm ^2. When crushed, the individual pieces become flakes,
