  The manufacturing method of a water-containing liquid (A) is not specifically limited. The method for producing the water-containing liquid (A) is, for example, a method in which the component (a1) is added to the component (a2) and mixed. At this time, the components (a3) to (a4) and the optional component of the water-containing liquid are dispersed in the component (a2) as necessary.

<Exothermic solid (B)>
The exothermic solid (B) contains an exothermic agent (b1) (component (b1)) that generates heat by a hydration reaction. When the exothermic solid (B) contains the component (b1), the exothermic solid (B) reacts with the water-containing liquid (A) to generate heat, and the water-containing liquid (A) is evaporated.

Next, 100 g of calcium oxide is put into a Dewar bottle. Immediately cover the Dewar bottle with a cork stopper and measure the water temperature (water temperature at the start of the reaction) 20 mm above the stirring blade.

The component (b1) is preferably a particle group. If it is a particle group, a contact area with a water-containing liquid (A) becomes large, and an exothermic solid (B) can generate | occur | produce more efficiently.
The average particle size of the component (b1) is preferably 0.5 to 10 mm, and more preferably 0.9 to 7 mm. If an average particle diameter is more than the said lower limit, the clearance gap between particle | grains will become large and a water-containing liquid (A) will osmose | permeate more easily. When the average particle size is not more than the above upper limit, the surface area per unit volume in the component (b1) is increased, and heat can be generated more efficiently.
(B1) The average particle diameter of a component is a value calculated | required by sifting and the following (s) formula.
Average particle diameter (mm) = Σ (Vi (%) + di (mm)) / Σ (Vi (%)) (s)
In the formula (s), Vi is an abundance ratio of particles having a particle diameter di (mm), and the particle diameter di is represented by an intermediate value between the meshes of each sieve.
Usually, in the equation (s), the arithmetic average particle diameter is calculated as Σ (Vi (%) + di (mm)) / Σ (100 (%)).

  The content of the component (b1) is preferably 30 to 100% by mass, more preferably 50 to 100% by mass, and more preferably 80 to 100% by mass with respect to the total mass of the exothermic solid (B).

  The exothermic solid (B) may contain an organic foaming agent (b2). The exothermic solid (B) can evaporate the water-containing liquid (A) more favorably by containing the organic foaming agent (b2). In addition, the exothermic solid (B) contains the organic foaming agent (b2), so that when the water-containing liquid (A) is evaporated, the white smoke-like vapor can be more easily recognized.

The component (b2) is pyrolyzed by heating to generate a large amount of heat, and generates carbon dioxide gas, nitrogen gas or the like (hereinafter generally referred to as foaming gas). The component (b2) is, for example, azodicarbonamide, p, p′-oxybis (benzenesulfonylhydrazide), N, N′-dinitrosopentamethylenetetramine, azobisisobutyronitrile, or the like.
Among these, azodicarbonamide is preferable as the component (b2) from the viewpoint of increasing the decomposition temperature and increasing the amount of foaming gas generated.
The content of the component (b2) is preferably 0 to 20% by mass, more preferably 1 to 20% by mass, and further preferably 5 to 10% by mass with respect to the total mass of the exothermic solid (B). If content of (b2) component exists in the said range, a water-containing liquid (A) can be transpired more favorably. In addition, if the content of the component (b2) is within the above range, white smoke-like vapor can be more easily recognized.

  The exothermic solid (B) may contain an optional component (solid optional component) other than the components (b1) to (b2).

  As a manufacturing method of exothermic solid (B), the method of mixing arbitrary components, such as (b1) component and (b2) component as needed, is mentioned, for example.

  The ratio (B / (A + B) percentage) of the exothermic solid (B) to the total mass of the water-containing liquid (A) and the exothermic solid (B) is preferably 40 to 90% by mass. If the B / (A + B) percentage is within the above range, heat is sufficiently generated while securing the time until the start of heat generation.

Below, the usage method of a smoke type transpiration agent composition is demonstrated.
For example, a container is placed on the floor of a space to be processed. The container to be used only needs to have an open upper end, and examples thereof include a flat dish, a deep dish, and a cup. The material of the container is preferably heat resistant, and examples thereof include metal, glass, and ceramics.

Put the exothermic solid (B) in a container.
The water-containing liquid (A) is brought into contact with the exothermic solid (B) in the container. The method of making it contact is not limited, The method of pouring a water-containing liquid (A) to the container containing exothermic solid (B) is mentioned.

When the hydrous liquid (A) contacts the exothermic solid (B) (that is, a mixture of the hydrous liquid (A) and the exothermic solid (B)), the water of the components (a2) and (b1) Due to the sum reaction, the component (b1) generates heat. At this time, the component (a1) slows the reaction rate between the component (b1) and the component (a2), and delays the transpiration start time of the component (b1).
When the mixture of the water-containing liquid (A) and the exothermic solid (B) reaches a specific temperature, the water-containing liquid (A) becomes a white smoke-like vapor and transpirations vigorously. At this time, the active ingredient (for example, propylene glycol contained as the component (a1), component (a3), etc.) contained in the water-containing liquid (A) evaporates and diffuses into the space to be treated. The diffused active ingredient exhibits antibacterial, bactericidal, insecticidal and other effects depending on the type of active ingredient. In addition, as for the ultimate temperature of the mixture of hydrous (A) and exothermic solid (B), 100-350 degreeC is preferable, for example.
While the mixture of the water-containing liquid (A) and the exothermic solid (B) is above a specific temperature, the water-containing liquid (A) is jetted. Since the water-containing liquid (A) contains the component (a1), the reaction rate between the component (b1) and the component (a2) is reduced, and the evaporation duration is lengthened. For this reason, all the active ingredients in the water-containing liquid (A) can be evaporated and diffused into the space to be treated.

The smoke-type transpiration agent composition of this embodiment vaporizes the water-containing liquid (A) vigorously by contacting the water-containing liquid (A) with the exothermic solid (B). For this reason, the active component can be diffused in every corner of the processing target space.
In the smoke-type transpiration agent composition of this embodiment, since the water-containing liquid (A) contains (a1), the transpiration start time of the component (b1) is slow and the transpiration duration of the component (b1) is long. For this reason, much of the water-containing liquid (A) can be evaporated.

(Smoke type transpiration device)
The soot-type transpiration device of the present invention comprises the soot-type transpiration agent composition of the present invention and a housing that accommodates the composition.
The smoke type transpiration apparatus of the present invention will be described with reference to an embodiment.

The housing 10 includes a bottom wall portion 12, a side wall portion 14 that rises from the periphery of the bottom wall portion 12, and a top wall portion 16 that is positioned at the upper end of the side wall portion 14. An opening 18 is formed at the center of the top wall 16.

Near the bottom wall portion 12 in the housing 10, a heat generating solid (B) is accommodated to form a heat generating portion 30.
A liquid container 21 is provided above the heat generating unit 30. The liquid container 21 includes a main body whose upper end and lower end are open, and a partition member 22 that closes the lower end of the main body. The upper end of the liquid container 21 is in contact with the top wall portion 16. The partition member 22 is separated from the heat generating portion 30. In the liquid container 21, the water-containing liquid (A) is stored to form a liquid storage unit 20. As described above, the liquid storage unit 20 and the heat generating unit 30 are partitioned by the partition member 22.

  A breaker 24 is provided in the liquid container 21 in the vicinity of the partition member 22. A pushing tool 26 that extends upward and protrudes from the opening 18 is connected to the upper surface of the breaking tool 24.

The material of the liquid container 21 may be any material that does not leak the water-containing liquid (A).
The partition material 22 of the liquid container 21 may be partitioned so that the liquid storage unit 20 (that is, the liquid container 21) and the heat generating unit 30 (that is, the housing 10) can communicate with each other. The partition material 22 is preferably a film that can be broken by a physical external force, such as a plastic film such as a polyethylene film or a polypropylene film, or a metal foil such as an aluminum foil.

The breaker 24 may be any member that can break the partition member 22, and examples thereof include a plate body in which a cutting blade or the like is formed on the lower surface.
The pushing tool 26 may be anything that can break the partition member 22 by pushing the breaking tool 24 downward when the upper end is pushed downward. The pusher 26 is, for example, a metal or resin rigid rod.

  The ratio of the water-containing liquid (A) and the exothermic solid (B) is the same as the B / (A + B) percentage in the above-described smoke-type transpiration agent composition.

An example of the manufacturing method of the soot type transpiration apparatus 1 is demonstrated.
The casing 10 that does not have the top wall portion 16 is filled with the heat generating solid (B) to form the heat generating portion 30. A liquid container 21 is provided in the housing 10.

The usage method of the smoke-type transpiration apparatus 1 is demonstrated.
The smoke type transpiration device 1 is placed in the space to be treated. The upper end of the pushing tool 26 is pushed downward, and the partition member 22 is broken. When the partition member 22 is broken, the water-containing liquid (A) in the liquid container 21 falls on the heat generating unit 30. When the water-containing liquid (A) falls on the heat generating portion 30, it flows between the components (b1), and the component (a2) comes into contact with the component (b1). When the component (a2) comes into contact with the component (b1), the component (b1) generates heat due to the hydration reaction.
When the component (b1) generates heat and reaches a specific temperature, the water-containing liquid (A) becomes a white smoke-like vapor and transpirations vigorously. Then, the steam is ejected upward from the opening 18. At this time, the active ingredient is diffused in the target space on the momentum of the jetted steam.
In this way, the entire amount of the water-containing liquid (A) is evaporated to the target space, and the desired effect is obtained.

  Although the above-mentioned embodiment is provided with the liquid container which provided the partition material in the lower end of the cylindrical molded object, the liquid container is not limited to this. The liquid container only needs to partition the water-containing liquid (A) and the exothermic solid (B). For example, the liquid container may be a bag formed of a resin film or a metal foil.

  In the above-described embodiment, the liquid storage part is formed above the heat generating part, but the present invention is not limited to this. For example, a heat generating part may be formed above the liquid storage part.

  In the above-described embodiment, the breaker and the pusher are provided, but the present invention is not limited to this. For example, the partition member may be broken by a sharp member without providing the breaking tool and the pushing tool.

Cladospodium cladosporeoids HMC1064 (bath isolate) was prepared by culturing at 25 ° C. for 1 week in a slant medium of potato dextrose agar (Difco). Sterilized 0.05% Tween 80 (manufactured by Kanto Chemical Co., Inc.) was used as the aqueous solution of bathroom isolates. A spore solution having about 1.0 × 10 ⁶ CFU / mL of colony-forming units of bathroom isolates was obtained. Next, 0.4 mL of this spore solution was inoculated into the test FRP20, and allowed to stand overnight at room temperature to dry and fix.
In addition, a colony forming unit (CFU, Colony Forming Unit) means the number of colonies produced when a certain amount of microorganisms (bacteria, etc.) are sown on a solid medium on which they grow.
Next, with respect to the obtained smoke-type transpiration agent composition, the water-containing liquid (A) was evaporated in the same manner as “<Transpiration start time>”. The position where the container was placed was the center P2 of the bottom surface 102 of the evaluation chamber 100. 90 minutes after contacting the water-containing liquid (A) and the exothermic solid (B), the air in the evaluation chamber 100 was evacuated, and the test FRP was collected. The bacterial solution was recovered from the test FRP by the following method 2. The collected bacterial solution was appropriately diluted with physiological saline so as to have a measurable concentration, and this was smeared on a potato dextrose agar medium. After culturing this at 25 ° C. for 5 days, the number of colonies formed visually was counted.

FRP for test inoculated with fungus and 10 mL of SCDLP medium (manufactured by Nippon Pharmaceutical Co., Ltd.) were placed in a sterilized plastic petri dish (manufactured by Aswan Co., Ltd.) and stirred with a conical rod (manufactured by Nissui Pharmaceutical Co., Ltd.) to extract the bacteria from the test FRP. .
The number of viable bacteria was determined from the measured number of colonies and the dilution rate of the bacterial solution, and the value was defined as the “number of bacteria after treatment”. Separately, the bacterial solution collected from the test FRP in the untreated section was appropriately diluted with physiological saline so as to have a measurable concentration, and smeared into a potato dextrose agar medium. After this bacterial solution was cultured at 25 ° C. for 5 days, the number of colonies formed by visual observation was counted. The number of viable bacteria was determined from the measured number of colonies and the dilution rate of the bacterial solution, and the value was defined as “the number of untreated bacteria”.
The number of bacteria obtained as “the number of bacteria after treatment” and “the number of untreated bacteria” is converted into a common logarithm (log), and the value obtained by subtracting the “number of bacteria after treatment” from the “number of untreated bacteria” (Δlog = log (the number of untreated bacteria) −log (the number of bacteria after treatment)) was determined, and the value was taken as the fungicidal efficacy. The fungicidal effect was evaluated from the value of the fungicidal efficacy based on the following evaluation criteria.

[Evaluation criteria]
A: Δlog is 4.0 or more.
A: Δlog is 3.0 or more and less than 4.0.
○: Δlog is 2.0 or more and less than 3.0.
Δ: Δlog is 1.0 or more and less than 2.0.
X: Δlog is less than 1.0.
