期待できる。According to the present invention, a particulate material containing quicklime is used as a snow melting agent. When quicklime reacts with water, it generates heat of reaction, and this heat has the effect of melting snow. Quicklime is also used as a fertilizer, and shows alkaline when dissolved in water, so it hardly affects the environment. Also, since the heat of reaction melts snow, it changes into a stable substance after the reaction and does not remain as quicklime. Furthermore, since it is granular, an anti-slip effect can be expected.

The portion (2) containing a large amount of quicklime should preferably be located at the center of the snow melting agent grain (1). However, in this embodiment, the portion is not at the center but is at a biased position because of easy production. When the snow melting agent reacts with water, the shape of the portion (2) containing a large amount of quick lime dissolves almost evenly from the surface, so even if only the portion (2) containing a large amount of quick lime remains, Since the initial snowmelt grain (1) shape is reflected, the portion with a high content of quicklime (2)
May be spherical.

The pressure is 20 kgf per grain (1) of the snow melting agent. The same applies to the method of forming the portion (2) containing a large amount of quicklime. The pressure is the high lime content (2)
It is 30 kgf per piece. This increases the pressure so as not to crush when forming the snow melting agent grains (1).

応後は安定な物質に変化し、生石灰としては残らない。Since the present invention is configured as described above, it has the following effects. In claim 1, when the particulate snow melting agent contains quick lime, quick lime reacts with water to generate reaction heat. This heat melts the snow. In addition, since quicklime shows alkalinity when dissolved in water, it hardly affects the environment. Furthermore, it changes into a stable substance after the reaction and does not remain as quicklime.
