Abstract

PURPOSE:To keep a compounding ratio by forming mists having respectively adjusted necessary densities and successively applying the same to the surface of an object to be coated at every kind. CONSTITUTION:Mists AS adjusted in density are carried upwardly by carrier gas CG and reach the surface of an object O to be coated, which is to be adhered thereto. The object O to be coated is further carried by a conveyor 10 to reach above the emission opening part of a fine particle forming apparatus 11 of pigment A. The fine particles of the pigment A are also applied to the surface of the coating film of a binder through the same process as the formation of the fine particles of the binder by the fine particle forming apparatus 11. Subsequently, the coating of pigment B being the next process is also performed in the same way. Further, in order to enhance the mutual adhesive strength of pigments, a binder is applied between the coating layers of the respective pigments. By this method, uniform coating can be performed and cleaning can be omitted.

Description

[Detailed description of the invention]

[Industrial Field of Application] The present invention relates to a toning method for applying pigments or dyes of different colors. [Prior art] Conventionally, when coloring pigments or dyes, etc., the desired shade (TL) was first determined, and in order to obtain the shade A, multiple colors were mixed in small amounts. The colors were toned. Originally, producing 11 colors was a very difficult process, and even if the mixing ratio was slightly different, the same 7 shades could be produced.''':)
: has been considered to be 1N11. Specifically, even if there is a difference in the blending ratio of -, it is not possible to produce the same shade. It is extremely difficult to get the smell as strong as the knees, and each one has 1! ! The reality is that this knowledge is kept secret as top secret know-how. In addition, when applying pigments toned in this way, the pigment and binder were first mixed and then applied. It is used to enhance the adhesion to the paint, but if the amount of the binder is less than 2O/100 by weight to the pigment, it will not adhere to the paint. Due to poor durability, it was actually necessary to use more than 2 binders.When mixing the pigment and the binder, the particles of the M material are branched (not molecularly dispersed) into the binder. Therefore, strictly speaking, the particles are not necessarily homogeneously dispersed.In particular, the smaller the particles, that is, the finer the particles, the easier they are to agglomerate (block). , when applied, flAl: in the form of 5 agglomerations or clumps (Bi, B, , B, . . . ) as seen in FIG.
)

[Who is it? At the beginning of coating or when the amount of coating is small, there is a gap (811 sin s,,,=) between the lumps (i31.B,, B,, -), that is, there are irregularities. It is necessary to fill in and level them out, and then apply more pigment to the first layer, that is, apply more pigment on the side to make it thicker. Therefore, it has been difficult to obtain an extremely thin and transparent coating film. However, the single tube used for the application required time and effort to clean the entire line every time the color changed λ, that is, every time the pigment was changed. [IM to be solved] The objective of the present invention is to set the compounding ratio of various colors such as pigments to a strict ratio of 1/1000, and to maintain these ratios. Furthermore, in order to be able to reproduce the $JIL system, it is also necessary to omit the cleaning work of the same equipment line when changing the blending ratio. [Means for solving R-opening] First, two aspects of the present invention: Generation of the track unit to be used.
Outline 1 explanation. Dowa 1. -There are various types of craftsmen,
For the time being, I will take up two types. One of them is a submerged foaming type. Figure 18 is #illustrated.
- Yes. A liquid is placed in a closed container (122), and a gas (A) is injected into the liquid from a gas jet nozzle (124).

becomes fine particles and disperses in the gas, producing atomized air (AS). The density of the atomized body (AS) is determined by the amount of gas ejected to a certain extent, i.e., by the pressure of the body (injected), or in other words, by the gradual adjustment of the amount of gas emitted.
〔can get. However, it is peculiar that the density of the smoke produced by the I7 method is relatively small (ρ'7''), which is the spray WJ type. In the hydraulic method, a liquid with relatively high density can be obtained, i.e., the liquid is sprayed from the nozzle (132) and it is applied to the collision plate (134) at F'Tchil!1-(,t This method is used to obtain fine particles that have been pulverized, rebounded, and scattered into the gas (such as fine dust).When using the cough method.By adjusting the supply of the liquid that is ejected, a fume is generated. There is a need to adjust to the body's density a'!!!All!
The force is lowered, and therefore the 819 force is also reduced (5. It becomes more difficult to turn the liquid into fine particles). ■ In order to solve the problem mentioned above, in the present invention No. 5, in the case of the present invention, jetting or spraying is performed intermittently at i' instead of t without changing the ejecting liquid pressure ♂. - 10 is what you are trying to get, and there is no P at all.
The number of oil bodies ejected is 11+7, and there is no doubt that one oil body will be ejected when the oil is ready, that is, when the pulp of the ejecting gun is opened. Therefore, the total amount of these eruptions is,! - It can be said that the total time when opening the opening is proportional to 1.:1.In that case, if the opening time is short, the application will be striped, but the spray m-type In the case of 2 milliseconds (ms), there is little concern. That is, by repeating the duration 5-millisecond 11, the density of the 7-mist mass 1i is completely uniform 4. This is what you get. Give @ and explain. First, I will give an example of an extreme case. If you want to obtain the density of smoke (1) for (1) when a continuous streak is 1 noise, please refer to the graphs of 11a (11a) and (1) (1) of (1) and (1) of (1). "1315" is the ejection pressure when ejected for 1 millisecond (InlI) in the] cycle
). Mathematically, the density of the aerosol will be -100,000 for continuous spraying. This is, of course, assuming that the density of the smoke for both continuous spinois is equal. Next, the blending ratio of the two-color pigment liquid atomizer was set to 1:8.
In the case of 5 (#Determine the mixture by converting it from the density of each liquid)#J, Su''i-, late Pa's The eruption during the J cycle was determined to be 34, and that of "dpfL" was determined to be 41111 (4: : M = 1811.5> i
t, that means it's okay. The premise of the present invention is to utilize buried bodies with different densities. In addition, as a practical matter,
In addition to 14 liquid density, viscosity, room temperature, humidity, ejection pressure,
It is not necessary to consider each factor such as the characteristics of the nozzle (and determine the blending ratio). The opening and closing of valves in the gun, such as the two series, can be easily set in milliseconds for cycle and intermittent times by using a commercially available pulse controller. 1".In addition, in such a short time 1111, 1l17$/i+, Misao!

Any of the following methods may be used: a rolling method, a rolling method, an l-ting method, etc.) or a lamination method. In the above-mentioned IIQ 1llfllll, the basic method was to first apply a binder to the R substrate, but due to the characteristics of the object to be coated and the 11W material, a binder may not be necessary. 1. In order to bond the pigment directly (sometimes it may be applied to the cloth), add a binder between the coated layers of the famous pigment. In this way, the combination of application orders can be easily selected depending on the application.
- The above coating is based on the adhesion of vII grains -f to the surface of the object to be coated due to A, j, - of the smoke electric body. Electrostatic coating can also be used. This state is also shown by the imaginary line in FIG. 2, r. In this case, it goes without saying that the materials to be handled must be non-ul1 emitting materials. However, there is also a method in which one crystal of each color is used to obtain the desired shade and then applied. In other words, a mixed coating power is used.

In addition to the application described in L, electrostatic application is also effective in the same manner as in the sequential application described in 1'jj. According to the method 7, it is possible to apply a thin layer to the nose, which means that the number of particles that should be distributed can be kept to the minimum necessary.
For example, fine particles of pigment are applied to the surface 1 of the object to be coated. 'Calculate the number N of fine particles that are arranged without gaps, that is, one layer j1
