Definitions

  • the present invention relates to an excrement disposal material and a method for producing the same.
  • Examples of conventional excrement disposal materials include those described in Patent Document 1.
  • the excrement disposal material described in the same document is composed of a plurality of granules having hydrophobicity (water repellency), and is used in a system toilet.
  • a system toilet is divided into an upper space and a lower space by a mesh-like sheet that allows urine to pass through.
  • a plurality of granules are laid in the upper space.
  • a liquid absorbent sheet is arranged in the lower space. After passing through the gaps between the granules, the excreted urine reaches the lower space through the mesh-like sheet. Urine that reaches the lower space is absorbed by the liquid absorbent sheet.
  • granules are formed that are mainly made of water-absorbing material and also contain salt.
  • salt By including salt in this manner, the liquid passage rate of the granular material can be increased. Therefore, even though a water-absorbing material is used as the main material, the hydrophobicity of the granules can be increased without performing hydrophobic treatment on the surface of the granules.
  • FIG. 1 is a schematic diagram showing one embodiment of the excrement disposal material according to the present invention.
  • the excrement treatment material 1 is an excrement treatment material used for treatment of excrement (mainly urine).
  • the excrement disposal material 1 may be an animal excrement disposal material used to dispose of the excrement of animals such as cats and dogs, or a human excrement disposal material used to dispose of human excrement. It may be wood.
  • the excrement treatment material 1 includes a plurality of granules 10 for treating excrement.
  • the excrement disposal material 1 is used, for example, in a system toilet that includes a box-shaped main body for receiving excreted urine and a partition that divides the internal space of the main body into an upper space and a lower space. The partition has a through hole through which urine passes. In that case, the excrement disposal material 1 is used with a plurality of granules 10 laid directly on the partition.
  • Each granule 10 has hydrophobicity. That is, the granular material 10 has the property of not absorbing liquid such as urine at all, or hardly absorbing it at all. In order for the granular material 10 to have hydrophobicity, it is necessary that the liquid passage rate measured by the following test be 60% or more. First, a granular material 10 (sample) equivalent to 50 g is placed in a sieve having an inner diameter of 10 cm and an opening of 1 mm. Place an empty beaker under the sieve.
