专利汇可以提供Snow-melting agent专利检索,专利查询,专利分析的服务。并且PURPOSE: To obtain a snow-melting agent which is capable of efficiently melting fallen snow to raise the earth temperature and enables effective utilization of brewers' lees by incorporating a heat generating substance into a vegetable incineration ash.
CONSTITUTION: A vegetable incineration ash (A), obtained by incinerating any one of or an appropriate mixture of an edible plant and brewers' lees in, e.g., an incinerator, is mixed with a substance (B) capable of undergoing an exothermic reaction with water or oxygen, such as an alkali or alkaline earth metal oxide or salt, or an iron powder, (e.g., quick lime) and, if necessary, additives (C) such as a heat storage substance, a reaction inhibitor, an organic or inorganic fertilizer, and a porous substance. This mixture is put into a mixer for sufficient mixing by agitation in an inert gas (e.g., an N
2 gas) or dry air atmosphere to prevent the heat generating substance from undergoing an exothermic reaction, thus giving an objective snow-melting agent.
