−７５１９０号で提案した。2. Description of the Related Art Conventionally, as a snow melting agent, there are salt, calcium chloride, urea and the like, but salt and calcium chloride generate rust or inhibit plant growth. Urea does not have such a drawback, but it does provide eutrophication due to the presence of nitrogen. The snow melting agent produced from dolomite does not have the above-mentioned disadvantages, but is difficult to produce. For this reason, the present inventor has proposed a snow melting agent comprising calcium acetate magnesium salt (CMA) produced from natural lightly burned dolomite Mg (OH) 2 as disclosed in Japanese Patent Application No. Hei.

え、効果的である。According to the present invention, since the snow melting agent 10 is baked 2, it has no moisture and can be powdered, so that it is easy to scatter and has good solubility, so that it has a quick effect. In addition, the slow-acting snow melting agent 11 obtained by granulating calcium acetate magnesium salt (CMA) obtained by a kneader-mixing reaction of lightly powdered dolomite and acetic acid with a granulator has a slow effect. Therefore, this snow melting agent 11
The snow melting agent 12 comprising 5% to 40% of a fast-acting snow melting agent 10 manufactured from magnesium hydroxide or magnesium carbonate (MA) has both slow-acting and fast-acting effects and is effective. .
