要因の一つである。Piping rehabilitation work to which the method of forming a coating film on the inner wall of a piping system according to the present invention is mainly applied has the following special characteristics. That is, firstly, since the inside of the pipe is painted, it is difficult to visually confirm the construction details. Second, since the paint is applied to a rusted pipe, it is more difficult to fix the paint film than on a newly installed pipe. For this reason, pinholes and incomplete coating film formation are likely to occur. Third, the construction costs are enormous. For example, in the case of a five-story building with 30 units and a total floor area of approximately 1,800m, the water supply pipe system will be approximately 1,600m long.In this case, the construction cost using the layered coating method will be approximately 10 million yen. In addition, in the case of hot water pipe rehabilitation work, it is usual that the cost per square meter is about 30% higher than the above cost.Fourthly, due to the above circumstances, the construction work is carried out both on the rehabilitation work itself and on the rehabilitation work itself. There is always anxiety about the results.For this reason, rehabilitation work currently relies on the track record and trustworthiness of construction contractors, and construction technology is not the main focus of selection.As a result, the prevalence of unscrupulous contractors, The current situation is that various problems are common, such as shoddy construction work.Fifth, work sites are difficult to see, such as inside buildings or underground, so they tend to get confused, and are not suitable for complex work. This is one of the factors that has hindered the progress of construction-related technology.

。[Prior Art] Against this background, in this type of technical field, reliable construction technology has not yet been established. For this reason, a single coating method, which is cost-effective, has conventionally been employed. This is done by removing the rust that has adhered to the inner wall of the piping, and then spraying pressurized gas from the inlet side to the outlet side.
This method transfers the paint and forms a paint film on the inner wall of the pipe. However, even if complete rust removal is achieved with this method, the paint is sprayed only once in one direction, so pinholes and Occurrence of unevenness could not be avoided. As a result, rust occurred and grew in areas where the paint film was incompletely formed, making it impossible to guarantee long-term rehabilitation work. Moreover, since conventional rust removal methods were incomplete, pinholes, uneven coating, etc. frequently occurred. Therefore, a layered coating method was proposed. This method is similar to the former method in that it is painted after rust removal and that pressurized gas is used, but after spraying the paint from the inlet side to the outlet side, it is sent backwards to each pipe connected to the main pipe. This method forms a coating film on the inner wall of the pipe by repeating this process for each branch pipe.
しかし、従来の前記重ね塗り法は同一塗料の往復塗装で

本願発明は、上記欠点を全て解消する配管系内壁の塗膜
形成方法を供することを目的とする。However, since the conventional multi-coating method involves re-coating the same paint, it has the following drawbacks. First, since the paint was the same, the coating film was formed by the base film,
The top layer was the same color, making it difficult for the owner and even the contractor to visually determine whether or not multiple coats had been applied. In particular, the interior of the piping was so dark that it was virtually impossible to see. Therefore, secondly, even if an unscrupulous contractor referred to one coat as multiple coats, the owner could not see through this. Thirdly, even if there were uneven coatings during overcoating, it was difficult or almost impossible to detect the presence or absence of uneven coatings because the base film and the top film were of the same color. As a result, even if there was a pinhole in the base film, it could not be covered by the top film. Fourthly, since it is a reciprocal painting process, special equipment is required, which further increases the construction cost. Fifth, because the painting is done back and forth, the work becomes complicated.
The drawback was that it was unsuitable for actual field work. Furthermore, sixthly, the more layers there are in multiple coatings, the smaller the inner diameter of the piping becomes, which is inconsistent with improving the flow of water and the like. In addition, the more multi-layered the coating, the higher the cost. The object of the present invention is to provide a method for forming a coating film on the inner wall of a piping system that eliminates all of the above-mentioned drawbacks.

Since visual inspections can be easily performed even by amateurs, construction inspections can be carried out easily, quickly and accurately, which can prevent the occurrence of pinholes, uneven coating, etc., and also prevent malicious construction. be able to. Furthermore, since visual inspection is easy, uneven coating can be easily detected, and a complete coating film without uneven coating or pinholes can be achieved. This makes it possible to extend the warranty period for pipe rehabilitation work and contributes to improving credibility of the rehabilitation work. Furthermore, there is no need to change the direction of painting, such as reverse feeding, and it is only necessary to change the paints for the base film and top film to the specified ones, so the work is simple and has the effect of being suitable for pipe rehabilitation work sites. It is also advantageous in terms of cost. Secondly, since the base film and the top film can be easily distinguished by color, it is easy to visually check whether the top film has peeled off or not, which has the effect of facilitating maintenance during pipe rehabilitation work. Since it is sufficient to form the coating film in two layers, the base film and the top film, there is an effect that the inner diameter of the pipe is not made too small.

目的を達成することができるのである。In order to carry out pipe rehabilitation work using the coating film forming method on the inner wall of the piping system according to the present invention, first, as a pretreatment, an abrasive is sent into the pipe l using pressurized air, etc. Remove any rust. After that, paint A is fed into pipe 1 using pressurized gas such as pressurized air, and
A base film 2 having a negative color is formed on the inner wall of the substrate. After painting,
The paint A becomes semi-dry in about 6 to 12 hours in the case of natural drying, and in about 2.5 to about 9 hours in the case of heated drying. In this state, another paint B is fed into the pipe 1 and coated on the base film 2. The thickness of the base film 2 is usually 0.3 m.
rrr" about 0.5 mm. After painting, paint B is completely dried by air drying for about 54 to about 15 hours, usually about 24 hours. As a result, the contrasting color (hereinafter referred to as A top film 3 having a contrasting color is formed.The thickness of the top film 3 is usually about 0.3 mm to 0.5 mm.The contrast color includes a contrast color in which the base film 2 and the top film 3 are complementary colors to each other. When there is a relationship between warm colors such as red and yellow and cool colors such as white and blue, when there is a relationship between chromatic colors such as gray,
There are cases where there is a relationship between an achromatic color such as white and a chromatic color such as blue, and there are cases where there is a relationship between a dark color and a bright color. According to recent color theory proposed by Moon and Spencer, it is known that there is a certain range of contrasting colors for a certain color. Therefore, for example, complementary colors do not necessarily have to be strictly based on the color scheme, and may have some range. Among the above contrasting colors, cases where they are complementary colors or cases where there is a relationship between warm and cool colors are more suitable for forming coatings on water supply pipes, cases where they are in a relationship between gray and chromatic colors, and cases where gray adjacent to black and white are more suitable. When there is a relationship between dark and light colors, it is more advantageous for forming a coating film on piping for hot water supply pipes. The reason why the base film 2 and the top film 3 are made in contrasting colors is as follows. For example, it has been proven in color theory that when the base film 2 and the top film 3 are complementary colors to each other, the two adjacent colors look outstanding. That is, when two colors that are complementary or have a similar relationship are placed side by side, for example, a red color and a blue color mutually enhance the other color, increasing the degree of saturation and making the color more vivid. This is called color contrast.
ast). At this time, if you stare at the boundary between the two colors,
Particularly striking contrasts can be seen along the boundaries. This is called border contrast. Therefore, if the base film 2 and the top film 3 are shown in FIG.
If there is uneven paint in between, edge contrast occurs along the boundary, making it extremely easy to spot uneven paint. If uneven coating is eliminated and the top film 3 completely covers the base film 2, there is no room for pinholes to occur.The above color contrast can also occur between gray and chromatic colors, where gray appears to have a pale color that is the opposite of the adjacent color. Therefore, in such a case as well, the base film 2,
If there is an uneven coating between the upper films 3, edge contrast occurs along the boundary, making it extremely easy to visually detect the uneven coating. Regarding gray, which has no color,
A kind of contrast occurs between two grays of considerably different brightness. In other words, gray adjacent to black appears white, and gray adjacent to white appears black. This is a comparison of brightness (
It is called brightness contrast). Therefore, in such a case as well, if there is uneven coating between the base film 2 and the upper film 3, edge contrast will occur along the boundary, making it extremely easy to visually detect uneven coating. . The same can be said for white and blue, warm and cool colors, and achromatic and chromatic colors.The paint A for the base film 2 and the other paint B for the top film 3 are of different colors. However, even if the colors of the paints before painting appear to be the same, the components are different, and as a result of painting another paint B on top of the base film 2, a chemical reaction occurs, and as a result, the top film 3 The color may be different from the base film 2, and the present invention also includes this case. In addition, if the paint A and the other paint B have different physical properties such as viscosity and shape, as well as having a different color,
As a result, the paint A of - and the other paint B complement each other, making it possible to form a stronger paint film in terms of strength and also being effective in preventing the occurrence of pinholes. Furthermore, since the formation of a coating film is sufficient between the base film 2 and the top film 3, the piping l
The inner diameter of the tube is not made excessively small. Next, in the method of forming a coating film on the inner wall of a piping system according to the present invention, there is no need to change the coating direction of the coating material A forming the base film 2 and the coating material B forming the top film 3, and the coating is applied twice in the same direction. It is painted. therefore,
There is no room for mistakes in work, even on sites that tend to be confusing. When the base film 2 and the top film 3 are of contrasting colors in this way, there is a color contrast, and a marginal contrast occurs along the boundary.
The visual inspection becomes self-explanatory, and as a result, the desired objective described above can be achieved.
