However, a thin coating can be applied skillfully with a smooth coating operation, and no iron brush that meets the following requirements can be found.
(1) The application amount can be adjusted. With respect to the surface to be coated, a fixed amount of coating liquid per unit area can be temporarily stored and constantly supplied to the working surface.
(2) Uniform coating can be applied to corners or parting edges such as window frames.
(3) By applying the coating while pressing the working surface, the coating liquid (wet film) can be extended or pressurized to increase the adhesion strength.
(4) A thin film having a dry film thickness of 1 micrometer or less can be formed.
(5) Since it is possible to attach and detach the planar fibers consumed from the main body, it is economical, and it can always be used in a new state.
[0007]
This invention is made | formed in view of such a situation, eliminates the said subject, and performs functional coating | coated with a dry film thickness of 1 micrometer or less by the manual work with respect to the object surface (same as a to-be-coated surface). Therefore, it is an object of the present invention to provide a trowel brush that can be used to apply a thin film coating with a smooth coating operation.
[0008]
[Means for Solving the Problems]
In order to solve the problem, the present invention relates to a iron brush used for manually applying a photocatalyst coating film or other functional coating to a target surface (same as a surface to be coated) ,
Coating action that stores the photocatalyst solution and other low-viscosity coating liquids internally, supplies the liquid channel to the working area, and makes it possible to select the change or transition of the working area for coating operations that form a thin film or ultra-thin film. a trowel brush formed by Katachi設plane, its characteristic structure, a body having an outline knife-like cross-sectional thickness shape, and the planar fiber which is detachably applied to the coated working surface of the body , comprising a manipulation handle, the coating acting portion, in which the Kyokudo acting portion corresponding to end effector and blade surface which corresponds to the cutting edge are continuously arcuate surface forming.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the accompanying drawings.
[0010]
As shown in the drawing, the embodiment (hereinafter referred to as an example iron brush) is detachable from the main body (1) having a substantially knife-like cross-sectional thickness and the application working surface of the main body (1) as described above. And a planar fiber (2) to be attached to the handle and an operation handle (3). In addition, as FIG. 9 shows other Example iron brush (Y), the operation handle (3) may be a straight blade type, and the attachment angle is not particularly particular.
[0011]
Coating the working surface, by Kyokudo acting portion corresponding to the blade surface end effector (11) corresponding to the cutting edge (12) continuously arcuate surface forming, a change or transition region of action of the coating operation It is configured to be freely selectable.
[0012]
Specifically, regarding the arc surface shape of the application surface, when the tip action part (11) corresponding to the cutting edge abuts on the surface to be coated (6), the bending body action part (12) corresponding to the blade surface The rising gradient [contact angle θ] is formed to be 45 ° ± 5 ° in the tangential direction. [Especially FIG. 8]
[0013]
Further, the main body (1) has a built-in liquid path element (5) for temporarily storing a coating liquid injected from the outside and (2) supplying the sheet fiber with permeation. The liquid channel means a liquid channel, and is synonymous with a pipeline through which the liquid passes.
[0014]
Here, the liquid passage element (5) has a width direction liquid passage (51) that receives a predetermined amount of coating liquid from the outside of the main body (1) and temporarily stores the liquid passage element (5), and a tip that is emitted from the width direction liquid passage (51). A plurality of fluid channels are arranged in the direction, and are composed of a distal-direction liquid channel group (52) that permeates and supplies the coating liquid to the distal-end action portion (11) and the planar fibers (2).
[0015]
The planar fiber (2) is a pile-woven cloth material, and is detachably attached to the working surface of the main body (1) via the hook-and-loop fastener (4).
[0016]
The coating liquid is a photocatalyst solution or other low-viscosity functional paint that uses water or an alcohol-based solvent. For example, there is a titanium dioxide solution.
[0017]
In addition, it is preferable to attach a protective cover capable of sealing or semi-sealing at least the application working surface. (Not shown)
[0018]
For reference, a photocatalyst solution (for example, a titanium dioxide solution) is applied to a glass surface (6) with a frame (7) using an example iron brush (X), and a thin film having a dry film thickness of 1 micrometer or less is applied. An outline operation (in the drawing, the vertical direction in the figure) when forming is described.
[0019]
First, a coating liquid corresponding to the area of the glass surface (6) is quantitatively supplied to the liquid passage element (5; 51, 52) in the main body (1), and the application working surface of the example iron brush (X) is directed downward. Then, the coating liquid is introduced into the planar fiber (2).
[0020]
The tip action portion (11) is brought into contact with the upper corner or upper parting edge between the frame (7) and the glass surface (6), and the coating operation is started from the top to the bottom in the direction of the handle.
[0021]
For the glass surface (6) [flat surface or flat portion], the working surface is smoothly moved from the tip working portion (11) so as to come into contact with the curved body acting portion (12) and is applied by movement.
[0022]
The wrist is turned back so that the tip action portion (11) is again brought into contact with the lower corner of the frame (7) and the glass surface (6) or the lower parting edge, and the action surface is changed to the curved action portion (12 ) Smoothly, and the application is finished by pulling up (ending operation).
[0023]
By repeating this coating operation over the entire glass surface (6), a functional film having a desired film thickness can be formed.
[0024]
【The invention's effect】
The present invention has the above-described configuration. According to this, the glass surface and other coated surfaces starting from the upper corner or the upper parting edge and reaching the lower part corner or the lower parting edge are smooth. Thin film coating can be applied to the entire coated surface skillfully while repeating various coating operations.
[0025]
Specifically, the following effects are exhibited.
(1) The application amount can be adjusted. With respect to the surface to be coated, a fixed amount of coating liquid per unit area can be temporarily stored and constantly supplied to the working surface.
(2) Uniform coating can be applied to corners or parting edges such as window frames.
(3) By applying the coating while pressing the working surface, the coating liquid (wet film) can be extended or pressurized to increase the adhesion strength.
(4) A thin film having a dry film thickness of 1 micrometer or less can be formed.
(5) Since it is possible to attach and detach the planar fibers consumed from the main body, it is economical, and it can always be used in a new state.
