Definitions
- the present invention relates to an exothermic agent for heating a smoke agent containing highly active calcium oxide and a method for heating the smoke agent using heat generated by a hydration reaction of calcium oxide with high activity.
- Smoke-killers are agents that smoke pest control substances by heating.
- a smoker containing a self-combustible substance such as nitrocellulose is reacted with a metal oxide and silicon (a so-called thermite reaction).
- a direct heating method is known, in which the smoke is itself self-burned by directly heating (igniting) at once using the heat generated by the fumes.
- the heating method by the thermit reaction is disclosed in Japanese Utility Model Application Laid-Open No. 62-144627 and Japanese Patent Laid-Open No. 1-288218.
