Description

[Detailed description of the invention]

[Industrial Application Field] The present invention is applicable to deodorizing films, vinyl chloride sheets, foam materials, fibers, nonwoven fabrics, paper, foods,
Fossil shells produced from the Toyama Mine and the Kokudo Takaoka Mine in Takaoka City, Toyama Prefecture are heated at 200℃ to 300℃ to make them easier to add to cosmetics, etc., to form into spheres and granules, and to mix with other deodorizing materials. This invention relates to a deodorizing material made of shellfish fossil powder that has been processed into a powder of 10 microns or less by evaporating the water content of the shellfish fossils through thermal processing at a temperature within ℃. [Prior Art] Fossil shells have been used for soil improvement, water quality improvement, feed, fertilizer, etc., but the deodorizing effect of shell fossils alone has not been measured and used as a raw material. That is,
Because it has been used for soil improvement, water quality improvement, feed, fertilizer, etc., there is no need to turn shellfish fossils into powder, and there are products that utilize physical and chemical adsorption properties to have a general deodorizing effect. (Example: Fertilizer that does not have the odor of chicken manure mixed with chicken manure)
It was processed into a powder of micron size or smaller and chemically tested for its deodorizing effect, but there was no technology or use of it as a raw material for the purpose of deodorizing. In addition, there are examples of mixing fossil shellfish powder of 50 microns or more with other deodorizing raw materials and deodorizing materials to enhance the deodorizing effect, but as in the present invention, it is possible to make the shell fossil powder into powder and take advantage of its deodorizing effect. Examples of products that can be easily added to films, vinyl chloride sheets, foam materials, fibers, non-woven fabrics, paper, foods, cosmetics, etc. as main deodorizing raw materials, are easy to form into spheres or granules, and are easy to mix with other deodorizing materials. do not have. [Problems to be solved by the invention] Conventional shellfish fossil powder has a minimum diameter of about 70 microns for use as feed, and even when used for the purpose of deodorizing effect, it is necessary to mix it with other deodorizing materials to form a powder. In addition, since there was no need to turn it into powder due to its use for odor pollution, the unique deodorizing effect of the fossil shellfish of the present invention can be utilized to produce films, vinyl chloride sheets, foam materials, and fibers as the main deodorizing raw materials. It is easy to add to nonwoven fabrics, paper, foods, cosmetics, etc., it is easy to form into spheres and granules, and it is easy to mix with other deodorizing materials, so it has not been available. [Means for Solving the Problems] The present invention heat-processes shellfish fossils produced from the Toyama Mine and Kokudo Takaoka Mine in Takaoka City, Toyama Prefecture at a temperature of 200°C to 300°C to evaporate the water content of the shellfish fossils. let 10
It is made of shell fossil powder processed into ultra-fine powder of less than a micron, increasing the surface area of porous particles,
By increasing the physicochemical adsorption power, it can be easily added to films, vinyl chloride sheets, foam materials, fibers, nonwoven fabrics, paper, foods, cosmetics, etc. as the main deodorizing raw material.
It is a deodorizing material that can be easily formed into spheres or granules, and can be easily mixed with other deodorizing materials. [Function] In the present invention, by pulverizing the shellfish fossil by the above method, the physicochemical adsorption power is increased several times more than that of conventional granules, so it can be used as a single deodorizing raw material. . That is, the deodorizing effect can be improved even with a small amount. Moreover, the shellfish fossil powder of the present invention is
It simultaneously adsorbs hydrogen sulfide (acidic type) and trimethylamine (alkaline type) elements, which is not found in other mineral deodorizing raw material powders. [Example] In this specification, fossil shells refer to the archaeological name,
On August 7, 1971, an analysis report was submitted by the Nagoya Bureau of International Trade and Industry regarding foraminiferal fossils, geological names, and samples of calcareous sandstone mined at Toyama Mine Iwatsubo A, B, and C quarries in Toyama Takaoka City. 54 Tsusan Kogyo No.
On October 20, 1976, the Nagoya Bureau of International Trade and Industry issued an analysis report (Table 1 of the quantitative analysis below) and samples collected at the Kunitachi Takaoka mine and excavation site in Takaoka City, Toyama Prefecture (No. 564). No. 1071) according to Table 2 of quantitative analysis below.

【table】

[Table] In addition, the shellfish fossils mined in Toyama Takaoka City are significantly different in composition and molecular assembly form from shellfish fossils mined elsewhere in Japan, and are characterized by a particularly high proportion of calcium carbonate. . Because they are different from other similar fossil shells, they are designated as a national resource. The shellfish fossils described above have been put to practical use as water quality improving materials, fertilizers, soil improving materials, and livestock feed. This is because the active adsorption, odor absorption, and water absorption properties of the fossil shell components and extremely fine porous calcite and aragonite, as well as ion exchange properties and physical and chemical effects, are promoted in parallel. be. Also,
This is because it has a pH of 8.6 to 10.0, so when mixed into acidic soil or acidic water, it has the effect of stabilizing them into weak alkalines. [Effects] With the above configuration, the present invention simultaneously adsorbs hydrogen sulfide (acid type) and trimethylamine (alkaline type) elements in a small amount by increasing the physicochemical adsorption power. In other words, it can be widely used as a raw material for deodorizing materials, and is reborn as a material with high practical value at a lower cost than other deodorizing materials.

[Table] (Resources) Toyama Mine, Block No. 99, 25001 R Kokudo Takaoka Mine, Block No. 104, 29008 R Most of the above mines are located in mountain forests within 50 nettles above sea level, and a layer of shellfish fossils lies several meters below the surface of the mountain forest. It forms a thick layer that extends 20 to 30 meters below sea level, and mining is done through open pit mining, and although natural resources are limited, they are abundant and resource utilization is meaningful. Fossil shellfish produced in other areas of Japan contain more than 28% less calcium carbonate and are extremely high in silicic acid. In other words, the shellfish fossils produced in both mines in Takaoka City, Toyama Prefecture are minerals with chemical functions and components that are currently not found anywhere else in Japan.
