Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a human waste adsorption deodorizer for pets such as dogs, cats, small birds, rabbits, chickens, etc., and poultry.

Conventionally, sand has been commonly used as a pet cat's urine adsorbent, but sand not only absorbs only a small amount of human urine and must be replaced frequently, but also has almost no deodorizing properties, and the sand grains may stick to the cat's paws. It had drawbacks such as being resistant to wear and staining the room.

It is also known that natural zeolite is sprinkled in chicken houses to deodorize chicken manure, but natural zeolite absorbs 20 to 3 Qcc/100 of urine! extremely small, about i';
In addition, in order to supplement the deodorizing properties, it is possible to use sand together with known deodorizing agents such as activated carbon and zeolite. However, they are not very good and are extremely expensive, making them unsuitable for this type of use.

As a result of various studies to solve the above problems, the present inventor discovered that calcium silicate absorbs a large amount of human urine and has extremely excellent deodorizing properties when absorbing human urine. The present invention was finally completed.

That is, the present invention has a specific surface area of 5 m2/! This invention relates to a human waste adsorption deodorizer for pets and poultry, which contains calcium silicate (excluding wollastonite) hydrate with a li' or more as an active ingredient, and contains 10 or more parts by weight based on the total weight.

The human urine adsorbing deodorizer of the present invention has a large amount of human urine absorbed, which reduces the frequency of replacement compared to conventional sand, and has good deodorizing properties in the state of human urine absorption, and can extremely prevent the occurrence of bad odors. Moreover, when exposed to direct sunlight, the stored human waste is diffused, making it possible to regenerate it.Coupled with the fact that calcium silicate is cheaper than zeolite and activated carbon, it is a great material for absorbing human waste for pets and poultry. Extremely useful as a deodorizer.

In the present invention, the calcium silicate used has a specific surface area (BET method) of 5 m2/g or more, preferably 25 m27g or more, because if the specific surface area is too small, the deodorizing speed and deodorizing effect will be poor.

Examples of such calcium silicates include calcium silicate hydrates such as C8H gel, tobermorite, Sheets dry, phoshagite, gyrolite, and hillebrandite, and those obtained by heating and partially dehydrating these hydrates. I can give an example.

Among these, C8H gel, tobermorite, sheeted dry, and phoshagite have a specific surface area of 25 to 400 m2/
It is especially desirable to have a large g.

The above calcium silicate has a urine absorption amount of 300 to 600C.
It has a large size of C/Ion and has extremely excellent deodorizing properties under human waste conditions.

The following table shows a comparison of the gas adsorption effects of calcium silicate, activated carbon, and natural zeolite.

As is clear from the above table, calcium silicate has a gas adsorption rate of more than 10% in a hydrated state, and the gas adsorption rate of activated carbon and naturally produced zeolite in a hydrated state is 2.41% and 4,46%. Much higher in comparison.

The adsorption deodorizer of the present invention may consist of the above-mentioned calcium silicate alone, or it may consist of calcium silicate and other components.

In the latter case, if the content of calcium silicate becomes too low, the above-mentioned characteristics of calcium silicate cannot be fully utilized, so the content of calcium silicate must be at least 10 weight more than the total weight. It is.

The weight ratio of calcium silicate to other components is appropriately determined within the above range depending on the use, purpose, etc.

Any other ingredients may be added to calcium silicate as necessary as long as they do not impair the properties of calcium silicate, but those that can contribute to economy, formability, quality, etc. as much as possible should be used. This is desirable.

Examples of such components include binders such as cement, gypsum, and bentonite, and human waste adsorption carriers such as Kanuma soil, rock wool, perlite, vermiculite, and basic magnesium carbonate.

The binder facilitates shaping of calcium silicate and prevents chalking of the surface of the shaped article.

The adsorbent deodorizing agent of the present invention may have any shape, such as powder, granule, or plate shape, depending on the purpose of use.

For example, when used for horizontal use, pellets with a short axis of 2 to LO mtrt and long axis of 10 mm or less or granular ones with a diameter of about 2 to 10 mm are preferable, and when used for small birds, plate-shaped ones are preferable.

When the adsorbent deodorizer of the present invention has a powder or granular form, the human waste adsorbing carrier and powder or granules formed from calcium silicate alone or a kneaded product of calcium silicate and a binder are mixed in an appropriate ratio. Can be used in combination.

In addition, if it has a granular shape, on the surface of the human waste adsorption carrier,
Calcium silicate or a kneaded mixture of calcium silicate and a binder may be coated.

Alternatively, all of the above materials may be kneaded and formed into a plate shape.

Table 3 shows the results of using the product of the present invention, naturally produced zeolite, and river crush (comparative products).
