塗布する方法に係わる。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for applying a liquid or a melt, and more particularly, to a method for applying a liquid or a melt as fine particles, that is, fine particles, which are smaller than the usual spray particle diameter.

みつかっていない。2. Description of the Related Art A spraying method such as airless spraying or two-fluid spraying is often used for applying a liquid or a molten material to a running object to be coated because of its simplicity.
However, there is still no good way to reduce overspray and rebound particles associated with spraying operations.

０μｍ以下の安定した膜をつくりだすことは難しかっ
た。[0003] Certainly, the electrostatic coating method in which spray particles are charged and applied to an object to be coated has been widely used in the general coating field because of improved coating efficiency.
It is known that the coating efficiency is extremely reduced when the speed of the object to be coated is increased. The spray particle diameter applied to the usual spray coating is generally 20 to 120 μm, but when the particle diameter is smaller than this spray particle diameter by one digit, that is, fine particles, almost no adhesion occurs. In a normal spraying method, a wet film thickness of 1
It was difficult to produce a stable film of 0 μm or less.

なか到達しないし、微粒子スピードが速くても、気流に
巻き上げられるため、塗着効率は著しく低下する。When the speed of an object to be coated is high, the decrease in the efficiency of applying fine particles is caused by an air flow over the object to be coated. If the speed of the fine particles ejected from the fine particle supply / discharge port is low, the air current becomes a barrier and does not easily reach the object to be coated. Even if the fine particle speed is high, the fine particles are wound up by the air flow, so that the coating efficiency is significantly reduced.

択されるべき事項であり公知技術といえる。Regarding the method of producing fine particles, the present inventors have already disclosed a method of applying while charging or dewing the fine particles, as well as a method disclosed in JP-A-63-93366 and JP-A-Hei.
The details are described in JP-A-189159, JP-A-1-310735, JP-A-1-304609, JP-A-2-229562, and the like. In the present invention, the presence or absence of charging or dew condensation on the fine particles is not particularly limited, and it is a matter which can be freely selected depending on the type of the object to be coated, the type of the liquid or the melt, and can be said to be a known technology.

え静電気的に帯電させたとしても付着率は低下する。When fine particles, particularly ultrafine particles having a small particle size, are electrostatically charged or dewed on a stopped object to be coated, they can be adhered to the object to be coated with a satisfactory value for the first time. . However, as the moving speed of the object increases, whether it is fine particles or ultrafine particles, an air current or a turbulent air flow is generated on the surface of the object, and the adhesion of the particles is hindered. Even if electrostatically charged, the adhesion rate decreases.

で、付着効率は一層向上する。This phenomenon becomes remarkable when the speed of the object 8 exceeds 20 meters per minute. Therefore, in the present invention, the first circulation moving body 1 is arranged on the upstream side of the fine particle coating outlet 10. If the gap between the article 8 and the circulating body 1 is set to zero or within a few millimeters, the occurrence of turbulence can be prevented, so that the adhesion rate of fine particles is improved. Further, in the present invention, the second circulation moving body 2 is disposed downstream of the fine particle discharge port 10. Thereby, the fine particles can be adhered to the object to be coated while suppressing the rebound flow of the fine particles, so that the adhesion efficiency is further improved.

Further, if electrostatic charge or the like is added to the fine particles, a value close to the result of the above-described adhesion efficiency when the object is stopped can be obtained. In order to expect even better results, the speed difference between the object 8 and the circulating moving bodies 1 and 2 is set to zero or ±
It is desirable to make it within 20%.

クレーパ９によって掻き取られる。In the embodiment shown in FIG. 2, instead of the fine particle discharge port 10, a spray flow of a liquid or a melt is made to collide with a circulating moving body to obtain fine particles, and the fine particles are applied on the surface of the object to be coated. It is. That is, at least the circulating moving bodies 1 and 2
The spray stream 5 sprayed by the spray generator 4 (hereinafter referred to as a nozzle) is caused to collide with any one of the above. Then, a thin film 7 is formed on the surface of the article 8 while generating fine particles 6 far smaller than the spray particles. Some of the fine particles attached to the circulating moving bodies 1 and 2 are scraped off by the scraper 9.

FIG. 1 shows that the first circulating moving body 1 has a role of preventing turbulent flow on the surface of the object to be coated, and the second circulating moving body 2 has a role of suppressing rebound of fine particles. This is the same as the embodiment described above.

In this case, in order to prevent interference between the lap portions of the spray flows 5 ejected from the plurality of nozzles 4, for example, the spray flows 5 in the odd-numbered order in the horizontal direction are transferred to the first circulation moving body 1.
In addition, by causing the even-numbered spray flow 5 to collide with the second circulating moving body 2, the interference of the luff can be smoothed. Further, the distance between the nozzle 4 and the collision point of the spray flows of the circulation moving bodies 1 and 2 is preferably 100 mm or less in order to increase the collision energy and generate finer particles.

It is desirable that the distance between the collision point and the object 8 at that time be 50 mm or less. Also, the rebound fine particles can be provided with a separate electrode and charged to further enhance the adhesion.In some cases, the function as an electrode is added to the circulating moving body itself, and even if the rebound particles are electrostatically charged.

Fine particles may be generated by colliding with the bodies 1 and 2 to form a thin film on the object to be coated.
Then, if the frequency of traverse is increased with respect to the moving speed of the object to be coated, a part of the fine particle pattern becomes over-coated,
A more uniform film thickness is formed.

For example, a web or coil of paper or plastic may be used as a one-way dummy instead of a belt and used repeatedly. Also, when forming a thin film by applying fine particles, it is known that it is difficult to form a stable thin film due to the air layer hindering the atmospheric pressure, and in the present invention, a more stable thin film is formed. In order to form, it may be applied in a vacuum.
