Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a cleaning agent.

[0002]

At present, in many cases, food materials used for lunch at elementary and junior high schools are collectively delivered unprocessed from wholesale markets and the like. In agricultural products such as delivered vegetables, pesticides are adhered and remain on the surface, and sodium hypochlorite is used for cleaning food materials in order to sterilize various bacteria. on the other hand,
In general households, synthetic detergents are used for cleaning food materials and tableware. In this way, sodium hypochlorite is used to remove pesticides and bacteria remaining on the surface of food materials such as agricultural products, and synthetic detergents are used in ordinary households. It is necessary to thoroughly wash the food material after use since there is a concern that the food may be taken up. Therefore, there has been a demand for removing pesticides and disinfecting with pesticides that are not harmful to the human body in place of sodium hypochlorite and synthetic detergents. In addition to the above-mentioned food materials, general households often use synthetic detergents for hand washing and cleaning, but many of these synthetic detergents are formed from petroleum-based chemical substances, which deplete petroleum resources. Hastened to be a problem.

[0003] In response to the above-mentioned problems, the present inventors crushed scallop shells that have been disposed of as waste, and the powder adsorbs chemical substances as compared with powder made of shells of other shells. And the effect of inhibiting the growth of bacteria is extremely high. In view of the above circumstances, an object of the present invention is to obtain a cleaning agent for removing and sterilizing chemical substances such as pesticides from scallop shells, and an object of the present invention is to effectively use waste materials.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has a calcium carbonate powder comprising a powder obtained by pulverizing a shell having a crystal structure having a calcite-type structure of calcium carbonate; An object of the present invention is to provide a detergent characterized by being mixed with a calcium oxide powder obtained by calcining a calcium powder, and to solve the above problem.

[0005]

Next, the present invention will be described in detail based on embodiments of the present invention. In order to obtain the cleaning agent, first, at least the main part of the shell is a shell made of a crystal structure of a calcite-type structure of calcium carbonate, this shell is a scallop shell, and most of the shell is made of this crystal structure Scallop shells differ from other shells in that In other words, in its ecology, scallops open and close their shells and release seawater vigorously to the outside, so they move quickly as described as "swimming in the sea" and escape from trappers (starfish etc.). In addition to having a large scallop so that this operation can be performed, the shell itself has conditions that it is relatively thin and lightweight and has strength, and the shell has a calcite-type structure of calcium carbonate. The inner shell side of the shell is formed by the foliate structure of the crystal structure of the shell, and the inner layer of the shell (the core layer in the shell thickness direction)
In the above, the calcite-type crystal structure of calcium carbonate has a plate-like structure, and the structure between the inner surface of the shell and the inner layer of the shell forms the main part of the shell (excluding the surface layer and hinges). Therefore, it is thin and lightweight, yet strong.

As described above, in the main part of the shell of the scallop, the calcite-type crystal structure of calcium carbonate has a leaf-like structure on the inner surface side (needle-shaped crystals are densely packed in a sword-like shape and laid. In addition, the shell inner layer has a plate-like structure of a calcite-type crystal structure of calcium carbonate (layers of needle-like crystals arranged in the same direction, such as plywood, overlap each other to form a needle-like structure). (The direction of the crystal is different for each layer.) As described later, the particles obtained from the shell of the scallop have a calcite-type structure and are porous. In contrast, other shells have a structure in which calcium carbonate crystals are spread in a plane and overlapped, giving a pearly luster. It does not exhibit quality.

As described above, scallop shells are used as a raw material for obtaining a detergent, but those that have been treated as waste after removing the scallop can be used, and useful waste can be used. . First, the collected shells are dried in the sun and dried and hardened. Next, the shells hardened by sun drying are crushed to a particle size of about 200 μm. The crushing method itself is not particularly limited, and an existing crushing device may be used. Thus, calcium carbonate powder is obtained, and the granules are porous granules. Next, a part of the calcium carbonate powder composed of the above-mentioned porous granules is used, put into a ceramic jar, and heated at a temperature of about 1000 ° C. for several tens minutes to several hours to obtain a calcium oxide powder. To get. Then, a detergent is obtained by mixing the calcium oxide powder thus obtained and the calcium carbonate powder.

[0008] In the above-mentioned detergent, the calcium carbonate powder is composed of unique porous particles of scallop shell powder as described above, and has a large adsorption effect. The calcium oxide powder is alkaline and shows bactericidal properties. Therefore, this cleaning agent has the effect of adsorbing chemicals such as pesticides, soaking the food material in a cleaning solution that is a mixture of this cleaning agent and water, or making the cleaning solution in a running water state and using the running water as a food material. By washing it against, it is possible to remove attached chemicals such as pesticides,
Alkaline action kills bacteria and mold. In addition to cleaning food materials, porous particles adsorb chemicals and fine contaminants attached to hands and the surface of the articles in hand washing and cleaning of dirty articles, and bacteria and the like are removed by alkaline action. To kill. After the washing with the washing liquid, washing with water is sufficient, and even if calcium oxide powder remains, it changes into calcium carbonate and is nontoxic to the human body, and can also contribute to the incorporation of calcium ions into the human body. The ratio of the calcium carbonate powder component and the calcium oxide powder component in the detergent can be appropriately changed, and by changing the ratio, the effect of deodorizing adsorption is improved or the effect of sterilization is improved. It can be higher and its proportion can be changed depending on the application.

[0009]

According to the present invention described above, if this detergent is used for cleaning food materials such as vegetables and for cleaning general soiled articles, chemical substances and fine contaminants adhering to the surface can be eliminated. It can be removed and sterilized. And, even if it remains after washing, there is an advantage that it changes to something harmless to the human body. In addition, since shells are used as a raw material, shells that have been disposed of as waste can be effectively used, which can greatly contribute to reduction of garbage. And the manufacturing method does not go through complicated steps, and has an effect excellent in practicality, such as providing the above-mentioned useful cleaning agent at low cost.
