(preventing and treating method)
Be to the target harmful arthropod that will prevent and treat or be sprayed to the zone that harmful arthropod is perched with the composition electrostatic spray by the implementation method of using above-described composition to prevent and treat the method for harmful arthropod.Electrostatic spray is undertaken by using electrostatic atomizer.
In electrostatic atomizer, liquid flows in having the spray electrode of tube shape.Voltage is applied in spray electrode and is arranged between near the reference electrode (sparking electrode) of spray electrode.This produces electrostatic force for flowing liquid in spray electrode.Should note the position of spray electrode and reference electrode relatively is not particularly limited.For example, spray electrode and reference electrode can be arranged to face with each other.Under electrostatic force, the liquid in the spray electrode has electrostatic repulsion, in order to liquid is divided into particulate.When liquid is sprayed, at the end of spray electrode liquid is carried out, for example, the circular cone jet mode.This spray method is as known in the art, as at Geoffrey Taylor, and Proceedings of the Royal Society, 1964, the 383-397 pages or leaves are delivered.In addition, preferably being applied to voltage between spray electrode and the sparking electrode is not less than 1kV but is not more than 30kV.
The suitable case description of electrostatic atomizer is in European patent application published numbers 1399265.Fig. 1 example this example of electrostatic atomizer.
Electrostatic atomizer shown in Fig. 1 has following configuration: wherein (i) spray electrode 1 that will have a tube shape is arranged in the pit 2 for spray electrode 1, described pit 2 is formed on the side surface (spraying discharging surface 5) of electrostatic atomizer main body, and (ii) will be arranged on corresponding to the sparking electrode 3 of spray electrode 1 in the pit 4 for sparking electrode 3, described pit 4 is formed on the side surface (spraying discharging surface 5) of the main body of electrostatic atomizer.The composition of packing into is sprayed composition is made the particle of mist from spray electrode 1.To be applied to sparking electrode 3 with the voltage of the opposite charge of composition (particle of mist), be attracted to sparking electrode 3 so that be in the spray particle of mist.In other words, sparking electrode 3 determines the wherein direction of the particle flow of mist.For example, spray electrode 1 comprises 27 rule (gauge) metal or conductive plastics capillaries, and sparking electrode 3 comprises the prong of being made by stainless steel, have the 0.6mm diameter.
Spray electrode 1 and sparking electrode 3 are electrically connected to drive circuit 10 via the metal tube 6 and 7 of corresponding band cover.Use this configuration, can apply voltage so that electrode serves as positive pole and another electrode serves as negative pole (for example, spray electrode 1 serves as positive pole, and sparking electrode serves as negative pole).
Spraying discharging surface 5 is made by dielectric substance.The spraying discharging surface 5 of the electrostatic atomizer of embodiment of the present invention is for example made by polypropylene.
In addition, spraying discharging surface 5 has the pit 2 that spray electrode 1 wherein is set and the pit 4 that sparking electrode 3 wherein is set, so that pit 2 and 4 is configured on the vertical direction (gravity direction).Electrostatic atomizer according to embodiments of the present invention, except the part corresponding to pit 2 and 4, spraying discharging surface 5 is plane surfaces.
Yet the discharging surface 5 of should noting spraying is not limited thereto.Spraying discharging surface 5 can be made and/or can be had curved surface by another kind of dielectric substance, condition is that (i) makes the composition of the mist of spraying out from spray electrode 1 charged fully, and therefore (ii) absorb to sparking electrode 3, in order to determine the direction that the composition of mist flows.
