【発明の詳細な説明】 ［産業上の利用分野］ 本発明はエアロゾルの塗布方法に係る。[Detailed description of the invention] [Industrial application field] The present invention relates to an aerosol application method.
［従来の技術］
従来のエアロゾル塗布方法の代表的例をあげると、第５
図に見られるように、液体り、などを加圧してスプレィ
ノズル５４から噴出し、それを硬板５５に衝突させて。[Prior art] A typical example of a conventional aerosol application method is the fifth method.
As shown in the figure, pressurized liquid is ejected from the spray nozzle 54 and collided with the hard plate 55.

その速度の下に被塗物００面に打当て、又は静電気など
（静電気印加装置５８）の力などにより被塗物Ｏｃ而面
に付着即ち塗布していた。The finer particles are transported to the surface of the object to be coated on the airflow of carrier gas CG, etc., into which they are introduced.
At this speed, it was applied to the surface of the object to be coated 00, or it was attached to the surface of the object to be coated by the force of static electricity (static electricity applying device 58).
［解決しようとする問題点］
上述の如く、エアロゾルの粒子はキャリアガス即ち搬送
気流に乗って被塗物面上に打ち当てられていたが、この
際、これらの粒子の跳返り（バウンド）は避けられなか
った。[Problem to be solved] As mentioned above, aerosol particles are carried by a carrier gas, that is, a conveying airflow, and hit the surface of the object to be coated, but at this time, the bounce of these particles is It was inevitable.
元来、微粒子（１ミクロン前後）というのは、表面積／

、慣性の力が小であるため、微粒子の周辺の気体の動き
に左右され易い、換言すれば、気体中の微粒子の運動速
度が終末速度に達するまでの時間は殆どなく、従って。Originally, fine particles (around 1 micron) have a surface area of
Although their weight is large, which means relatively large air resistance, their inertial force is small, so they are easily affected by the movement of the gas around them.In other words, the speed of movement of particles in the gas is influenced by the movement of the gas around them. There is therefore little time to reach terminal velocity.
エアロゾル粒子の初速度と気体の流速とは殆ど無関係な

径（μ■） 終末速度に達する時間（■５）
１０ ０．９４１
０．０１１上記の如く、殆ど瞬間的に
終末速度に達するのである。The initial velocity of aerosol particles is almost unrelated to the gas flow velocity. According to 9 documents, William C. Hines, "Aerosol Technology" Benjo Shoin (1980), particle size (μ■) time to reach terminal velocity ( ■5)
10 0.941
0.011 As mentioned above, the terminal velocity is reached almost instantaneously.
即ち、エアロゾル粒子は、殆ど瞬間的に気体の流速と等
しくなるのである。That is, the aerosol particles almost instantaneously become equal to the gas flow velocity.
従って、静止気体中では、エアロゾル粒子は殆ど動かな

リアガスの流速を上げると、エアロゾル粒子は、それと
殆ど同速となり、被塗物面上に衝突し、跳返り現象が発
生し、付着効率が低下するのである。Therefore, in a stationary gas, aerosol particles hardly move, and the time it takes for them to reach the object to be coated becomes longer. On the other hand, when the flow velocity of the carrier gas is increased, the aerosol particles have almost the same velocity and collide with the surface of the object to be coated, causing a rebound phenomenon and reducing the adhesion efficiency.
その効率を上げるために、一般に静電気が利用される。To increase its efficiency, static electricity is commonly used.
ただし、静電塗布方法というのは、被塗物が帯電性の高
いもの、例えば電気絶縁フィルム等の場合、過剰帯電に
より火花放電し、被塗物を破壊したり、また液体が可燃
性の溶剤であれば、引火爆発の危険性もあるのである。However, when using electrostatic coating, if the object to be coated is highly charged, such as an electrically insulating film, an excessive charge may cause spark discharge and destroy the object, or the liquid may be a flammable solvent. If so, there is a risk of ignition and explosion.

塗布方法を実施することであった。As mentioned above, the motivation of the present invention is to reduce bounce of aerosol particles during coating to increase coating efficiency, and at the same time, to implement a safe coating method by eliminating damage to the coated object or danger caused by electrical discharge. Was that.

があると言われている。[Means for solving the problem] As mentioned above, very fine aerosol particles (for example, around 1 micron) are moved by a carrier gas and are applied to the surface of the object to be coated with kinetic energy at a certain speed. Collision above. However, the force with which these fine particles adhere is a van der Waals force or an attractive force due to slightly charged static electricity, and has very low energy. On the other hand, the rebound energy converted by the collision with the object to be coated is larger, making it difficult for the aerosol particles to adhere. It is said that there is a difference of three times.

ロゾルの塗布方法である。The gist of the present invention is to provide a method in which an aerosol generated by an aerosol generation device is guided onto the surface of a workpiece, in which solvent vapor is present in the gas, and the workpiece placed in the vapor is The solvent vapor contained in the aerosol is cooled to below the saturation point, thereby causing the solvent vapor contained in the aerosol to condense on the surface of the object to be coated. The above-mentioned aerosol dispersion 'if (hereinafter referred to as particles) that has been led is deposited on the membrane surface, and then the above-mentioned liquid film-like solvent is evaporated, and only the remaining aerosol particles are applied. This is a unique aerosol application method.

（１）液体の場合 先ず、従来のエアロゾル生成方法を簡単に説明する。(1) In case of liquid First, a conventional aerosol generation method will be briefly explained.

部２２内に運ぶ。Refer to FIG. 1, the liquid is pumped up and ejected from the spray nozzle 4 in the chamber 2, and the spray is hit against the hard plate 5 to obtain fine particles. At the same time, the solvent in the liquid is also vaporized, and an aerosol ΔS consisting of these gases and fine particles is generated. On the other hand, a necessary gas G is introduced from below the chamber 2, and this carries the aerosol As into the application section 22 as a carrier gas CG.
上記エアロゾル内の気体には、上述の如く溶媒の気化し
た蒸気が含まれており、これらは飽和状態に近いことが
望ましい。The gas in the aerosol contains vaporized solvent as described above, and it is desirable that the gas be close to a saturated state.
塗布部の下方には、冷却装置２３に接続された冷却盤２
５が設けられており、該盤上に被塗物○ａが置かれる。Below the application section, there is a cooling board 2 connected to a cooling device 23.
5 is provided, and the object to be coated ○a is placed on the board.

霧滴上に付着する。, the nuclear coating object Oa is cooled down to a temperature lower than that of the solvent vapor in the coating area. As a result, the solvent vapor condenses on the surface of the object to be coated (see Figure 2).The fine particles R carried by the carrier gas collide with these condensed mist droplets, but the liquid in these mist droplets is As a result, the kinetic energy of the fine particles is absorbed, the bounce is reduced, and the fine particles are deposited on the same droplets.
なお、これら５Ｉｓ７１Ｉが多数集合すると、第３図に
示すように、液膜状Ｓｆとなって、被塗物面上を一面に
覆い、微粒子のバウンドをより少なくすることができる
のである。When a large number of these 5Is71I aggregate, as shown in FIG. 3, they form a liquid film Sf that completely covers the surface of the object to be coated, thereby making it possible to further reduce the bounce of the fine particles.

こらない。(2) In the case of a molten body This is a case where an aerosol of a molten body containing no solvent is generated. Referring to FIG. 4, the heated liquid melt HM is ejected from the spray nozzle 34, hits the hard plate 35, and becomes fine particles. However, since no solvent is included as in the case of the liquid described above, an aerosol consisting of 11 solid particles of the melt is produced. It is carried by the carrier gas and reaches the coating chamber 42 . A cooling plate 42 is provided in the lower part of the same room.
+jt As mentioned above, since the aerosol in the same room does not contain a solvent, no dew condensation phenomenon occurs due to cooling.
