均以下の性能しかないと云わざるを得ない。The results of the measurement by the above measuring method are as follows: apparent specific gravity = 0.56, water absorption = 1.6 times, nodulation force =
Δ was obtained. Since the water absorption is usually more than twice, it can be seen that the water absorption is considerably low. In appearance, the applied salt solution keeps the surface of the granules forever wet and sticky. When the granules were cracked, the water did not reach the center of the granules. Regarding the nodule forming power, a part of the coating composition on the surface was dissolved by water, the granules stuck to each other and the shape was broken, and the formation of nodules was slightly recognized, but the viscosity was reduced. Because of its weakness and slow drying, no sufficient baby lumps were obtained. Therefore, it can be said that the appearance in the unused state is good, but the basic performance is less than the average performance.

非常に経済的であると言える。In Comparative Example 1 not impregnated with the urine absorption promoter, the results were as follows:
It can be seen that whether or not this is impregnated also affects the nodule formation power. That is, it is considered that by impregnating this, urine is more smoothly transferred to the nucleus granules composed of the papermaking sludge, and the moisture of the surface absorbent material coating layer is kept in an appropriate state. As a result, it can be seen that the result regarding the nodule forming power of the example is excellent by about 1.5 ranks. Thus, the pet excrement absorbent of the present invention can form a nodule with a small amount, which is very economical.

る。In Examples 8 to 10, the absorber coating layer was spray-treated with a surface stabilizer to prevent powdering and powder falling. As shown in Table 1, the measurement results of these powdering rates are 2.3 to 0.2%, and the measurement of the powdering rate of Comparative Example 3 in which the surface stabilizer is not sprayed is shown. Compared to the result of 5.0%, there is clearly less powdered material, and the effect of the surface stabilizer is recognized. Among them, particularly, the glycerin solution of Example 10 was made to have a concentration of 10%, and 27.4 g of the glycerin solution (50% of the water constituting the core particles in terms of the stock solution) was used.
% Of the total weight of the excrement absorbing material in the powder state, which constitutes the papermaking sludge and the absorbing material coating layer), is sprayed to the absorbing material coating layer, and the powdering rate Is 0.2%, which is an extremely good result. However, when other performances are also considered, it is considered that Example 8 can be evaluated as having the best balance.

違和感を感じないものとなる。Therefore, if the pet excrement absorbent of the present invention is laid to a predetermined thickness in a pet toilet,
The urine excreted from the pet is first absorbed by the absorbent material coating layer formed on the surface of the urine-applied granules, but gradually migrates to the papermaking sludge constituting the core granules, and Will be taken into this.
The urine transferred to the nuclei particles has a deodorant impregnated in the nuclei particles, so that the malodor mainly including the ammonia odor is removed, and the nuclei particles are almost odorless. Furthermore, since the urine is contained in the granules (the core granules and the coating layer of the absorbent material), the deodorizing performance is further improved, so that even when placed indoors, the user does not feel uncomfortable or uncomfortable.

The sludge also migrates to a certain extent in the papermaking sludge and is taken into it. Since it will be absorbed more quickly, the amount of water flowing down to the pet excrement absorbent particles located in the lower layer will be reduced when it is used by laying it in pet toilets, etc., and the water absorption capacity of each individual particle will be wasted. It can be used without it.
