性的にも好ましくないものとなっていた。The conduit groove recess is a minute recess, and the depth and size (width, length) of the recess vary widely. The cross-sectional shape is U-shaped, V-shaped, mortar-shaped,
There are various shapes such as spherical. Therefore, the surface tension, viscosity,
Due to the influence of wetting and the like, the penetration of the coating material into the minute recesses is different from that of other surface portions. If the paint does not get into the minute recesses, cissing and bridging of the paint occur in the minute recesses, and as a result of foaming and pinholes due to air expansion in the minute recesses, the minute recesses are not colored. It may be left as a part. On the other hand, when the minute recesses are shallow, the recesses are filled with the paint and are colored dark. As described above, the imperfections such as uncolored or deep-colored color are generated in the minute recesses in the obtained coated product, the designability is deteriorated, the coating film has a defect, and the physical properties are not preferable.

まれる。After the coating material is applied, a high-speed air flow associated with air suction is uniformly applied to the surface of the base material to remove the excess coating material. This high-speed airflow is formed as a flow in a direction (preferably an angle direction of 15 to 90 degrees) oblique to the recess of the conduit groove on the surface of the substrate. As a result, a negative pressure due to air suction is exerted in the conduit groove recess, air and excess paint in the conduit groove recess are sucked, and the surface paint is drawn into the conduit groove recess, and in the conduit groove recess. Repelling of paint and bridge phenomenon are eliminated. Since the high-speed air flow due to the air suction is formed so as to be oblique to the conduit groove recess, the high-speed air flow acts more strongly in the conduit groove recess than at the surface and at a high speed, and the paint in the recess moves. Be drawn into.

とができる。As a method for causing a high-speed air flow associated with air suction to uniformly act on the surface of the substrate so as to be oblique to the recess of the conduit groove, a coating impregnation adjusting method proposed by the applicant of the present application JP-A-62-277184) is preferably adopted. In this method, a liquid material is supplied into a dipping box having a supply port and a take-out port for a base material, exceeding the level of the feed port and the take-out port, while the suction chamber is depressurized to reduce the pressure in the dip box. This is a method of preventing the liquid material from overflowing from the supply port and the outlet, and applying and impregnating the liquid material on the substrate while the substrate moves from the supply port to the outlet. High-speed air flow is generated at the outlet due to air suction in the immersion box,
This makes it possible to remove the liquid material that is excessively applied and impregnated on the surface of the base material. In such a method, the base material is conveyed parallel to the fiber direction and supplied into the dipping box through the supply port, and the outlet is extended outward so that its tip is at an arbitrary angle with respect to the base material conveyance direction. By obliquely sloping, a high-speed air flow associated with air suction is obtained in a direction oblique to the conduit groove recess. The velocity of the obtained high-speed air flow depends on the strength of the air suction force and the size of the space between the outlet and the substrate surface.
Further, since the treatment time by the high-speed air flow depends on the height of the carrier speed of the base material, the coating amount of the coating material applied on the surface of the base material can be arbitrarily adjusted by adjusting these factors.

できる。Even when the above-mentioned conduit groove recess is a pseudo conduit groove recess formed by embossing or the like, the same operation and effect can be obtained by the same processing. In other words, gypsum board, cement board, inorganic material such as calcium silicate board, fiber board, plywood with a decorative sheet attached, wood shaving board, wood material such as cement board, base material such as organic / inorganic composite material A pseudo conduit groove recess is formed on the surface by embossing etc., and a high-speed air flow associated with air suction is made to act obliquely with the pseudo conduit groove recess to form a coating layer with a substantially uniform film thickness. It can be formed following the surface of the base material including the recesses of the pseudo conduit groove.

で好ましくない。In the above treatment, it is essential that the high-speed air flow associated with the suction of air acts in a direction oblique to the recess of the conduit groove on the surface of the base material. Since the conduit groove recess is extremely narrow, when a high-speed air flow acts in a direction parallel to the conduit groove recess, it acts on the entire conduit groove recess at the same time, and air is sucked into the conduit groove recess. However, it is not preferable because there is no time for the surface coating material to be drawn into the conduit groove recess and the action of the high-speed air flow is released, resulting in the formation of no coating layer in the conduit groove recess.
