Apparatus of etching non iron metal for interior and exterior finishing of buildings}

The present invention relates to an etching treatment apparatus for the corrosion treatment of the surface of the non-ferrous metal used as interior and exterior materials of various buildings, in particular, the surface of the non-ferrous metal introduced from one side of the device by a continuously formed etching treatment tank and a plurality of cleaning tanks, removal tanks Etched and washed with polished or patterned surface, it can be discharged, so that non-ferrous metal panels for interior and exterior materials etched with high quality can be obtained, as well as mass production, which can reduce production costs and have a beautiful appearance and aesthetics. The present invention relates to a surface etching treatment apparatus for nonferrous metals for interior and exterior materials of buildings, which can greatly improve the finishing effect of interior and exterior materials of buildings.

Interior and exterior materials of non-ferrous metals used in elevator interior panels, etc. are usually formed on the surface of the non-ferrous metals such as aluminum, stainless steel, copper plate, etc. in various patterns and patterns, so the glossy surface and etching of the surface of the interior and exterior panels The beautiful interior and exterior materials of the building by the cotton, while improving the aesthetics to form a higher quality interior, exterior.

In addition, the interior and exterior non-ferrous metal material for the building is to form a variety of patterns and patterns by the method of painting and decorative signboard, stain immersion, silk screen, etching (etching), among which the formation of a variety of patterns and patterns Since this possible etching method has higher added value, non-ferrous metal panels for internal and external materials which have been etched in recent years are widely used.

Since the surface of the non-ferrous metal for the interior and exterior materials can take a variety of patterns and corrosion forms, such as a single pattern, a four-sided continuous pattern or a glossy surface and a corrosion surface formed at the same time, it is widely used in various fields and elements.

In addition, in order to etch the non-ferrous metal panel described above, by spraying or impregnating a corrosion solvent on the surface of the patterned non-ferrous metal panel to clean the corrosion solvent of the non-ferrous metal panel whose surface is corroded after a certain time and to remove various foreign substances. The finished non-ferrous metal panel is dried at room temperature for a certain time, and is supplied on site in a packaged state.

However, the non-ferrous metals for interior and exterior materials of the building as described above are very primitive and complex, so that not only the interior and exterior materials of uniform quality can be obtained, but also the corrosion state is not uniform and the reflectivity is poor in the case of glossy surfaces. There is a problem of low value.

That is, the etching treatment method that has to go through the multi-stage work process is usually the printing step of the workpiece to be used as the interior and exterior materials, the corrosion step to put the corrode to the surface of the workpiece, and the water to be corroded again. A non-ferrous metal panel having a predetermined pattern is formed through a washing step of putting in a tank, a removing step of putting a caustic soda tank in order to remove the printed layer of the washed object, and a washing step of putting it in a water tank again.

In order to perform each process, the work time is delayed by the repeated movement and transport of the processed object, and the occurrence of defective products due to careless handling is frequent. In particular, each process is separated because a plurality of process-specific devices are separated from each other. Indoor space utilization by the star device is significantly reduced.

In particular, in the above-described corrosion step, the production amount varies greatly depending on the skill of the operator, and the corrosion quality thereof is not uniform, and thus there is a limit to producing a higher quality interior and exterior materials.

The present invention is designed to eliminate the problems described above, and automatically transfers the workpiece on the feed roller, and removes the etching treatment tank, the first cleaning tank, the first cleaning tank, the second cleaning tank, and the second removal, respectively. The tank and the third washing tank are sequentially transported to perform the etching process, the cleaning solution of the corrosion solution, the acid resistant ink removal process, the caustic soda washing process, the residue removing process, and the final washing process, respectively.

Not only can you obtain high-quality building interior and exterior panels with uniform and stable etching, but also the injected processed materials are automatically etched and discharged through each process, which greatly improves the production speed and enables mass production. It is an object of the present invention to provide an apparatus for surface etching treatment of nonferrous metals for interior and exterior materials of buildings, which is very economical because it can reduce the cost.

As a technical means for achieving the above object, a plurality of discharge means for injecting a variety of solvents on the surface of the object to be treated, a solvent collecting means for collecting the solvent injected into the discharge means, the collected solvent is circulated It consists of a conveying means made of a conveying roller rotating at the same speed for conveying the circulating means for supplying, the supplied workpiece to each process step.

Opening and closing holes 70 are formed in the center of the cover 3 of the tub 30, the second washing tank 40, the second removing tank 50, and the third washing tank 60, respectively. Is configured to be removed.

In addition, the discharge side of the etching treatment tank 10, the entry and discharge side of the first washing tank 20, the first removing tank 30, the second washing tank 40, the second removing tank 50, On the discharge side of the three washing tubs 60, the feed rollers 1, 1 'are removed, and the rollers 72, 72', which are vertically symmetrical, are rotatably mounted, and the rollers 72, 72 'are rotated. Or to remove various solvents remaining on the surface of the workpiece 100,

At both ends of the collecting plate 4 of the etching treatment tank 10, a barrier wall 13 and 13 ′ having a collecting hole 12 are formed, and the fluid flowing out of the collecting plate 4 is collected in the collecting container 6. ) Can be collected internally,

Another spray nozzle 2 'is upwardly mounted on the lower portion of the transfer roller 1, 1' in the second washing tank 40, the second removing tank 50, and the third washing tank 60, and the water collecting tank By connecting to the circulation pump (7) mounted on the (6), the fluid in the sump (6) can be sprayed to the upper and lower surfaces of the object 100, the cleaning and spraying action can be improved more.

The surface etching apparatus for non-ferrous metals for interior and exterior materials of the present invention as described above will be described in more detail with reference to the accompanying drawings.

When the acid-resistant ink is printed on one side of the workpiece 100 to be corroded by a predetermined pattern or drawing, and it is injected from one side of the etching apparatus, a plurality of simultaneous rotations by a driving motor (not shown in the drawing) are performed. The workpiece 100 introduced by the feed rollers 1 and 1 'is introduced into the apparatus.

The treated object 100 thus entered is first introduced into the etching treatment tank 10. At the same time, the corrosion solvent by ferric chloride (FeCl ₃ ) is injected from the spray nozzle 2 mounted downward. Sprayed onto the surface.

Therefore, the surface of the workpiece 100 is corroded by the above-mentioned corrosion solvent, and this corrosion time is performed while the workpiece 100 passes completely through the etching bath 10, and this corrosion time is transferred. It is possible to adjust the degree of corrosion by adding or subtracting the rotational speed of the roller (1) (1 ').

The corroded object 100 passes through the etching treatment tank 10 to the first washing tank 20 on one side thereof, and a small amount of antifoaming agent is sprayed from the injection nozzle 2 inside the first washing tank 20. The mixed water is sprayed onto the surface of the workpiece 100 so that the above-mentioned corrosion solvent is washed so that the corrosion does not proceed any further.

In addition, the antifoaming agent is mixed with the purpose of making the circulating pump 7 circulating the washing water more smoothly while improving the washing efficiency by removing the foam of the washing water generated in the washing process.

The treated material 100 in which the corrosion solvent is washed is transferred back to the first removal tank 30. In the first removal tank 30, 5 wt% to 10 wt% of caustic soda and 90 wt% to 95% of water are used. The removal solvent mixed with the weight% is sprayed on the surface of the workpiece 100 through the injection nozzle 2 so that the acid-resistant ink on the surface is removed.

In addition, the caustic soda is a strong alkali, which is to neutralize the acid ink quickly to be removed, to completely remove the acid ink required only in the corrosion process to obtain a treated object having only a corrosion surface.

In addition, the caustic soda washing water sprayed by the first removal tank 30 is removed again by the second washing tank 40, in which the second washing tank 40 1% to 3% by weight of detergent and water 97 The washing water mixed with the weight% to 99% by weight is sprayed through the spray nozzle 2 so that the caustic soda washing water on the surface thereof is completely washed, and another spray nozzle on the lower side of the transfer roller 1 or 1 ' 2 ') is installed upward so that the upper surface as well as the lower surface of the object 100 can be washed.

The object 100 thus washed is transferred to the second removal tank 50 by the transfer roller 1, 1 ', and in the second removal tank 50, lactic acid (sulfuric acid) 3 wt% to 5 The removal solvent mixed with 95% by weight to 97% by weight of water completely removes various foreign substances remaining on the surface of the object 100 as well as rust on the surface to make the object more shiny and clean. .

Here, the lactic acid (sulfuric acid) has a strong dehydration action and metal dissolving power while decomposing organic matters, and decomposes various foreign substances, corrosion solvents and removal solvents, and cleans and polishes the treated object with a glossy surface. This improves the reflectivity of the polished surface while making the corrosion pattern of the corroded surface clearer.

The processed object 100, which has undergone the residue removal process, passes through the third washing tank 60, which is the final stage. In the third washing tank, water containing a small amount of detergent is sprayed at a high pressure to remove the lactic acid. And the final foreign matter will be completely removed.

In this way, each of the processed materials can be obtained an internal and external non-ferrous metal panel etched by a pattern or pattern desired by the producer, and the processed materials can be treated with an etching treatment part while the reflectance of the polished surface is significantly improved. It is also very stable and clearly formed.

In addition, as illustrated in FIG. 3, the etching treatment tank 10, the first washing tank 20, the first removing tank 30, the second washing tank 40, the second removing tank 50, and the third washing tank are described. A filter net 5 is formed on the upper portion of the sump 6 of 60 to remove impurities of various solvents circulated by the circulation pump 7 to make the surface of the workpiece 100 more clean. On both sides of (5), the inclined collection board 4 is formed, and the various solvents falling to the bottom become the inside of the sump 6 easily, without leaking to the outside.

In addition, since the discharge pipe 11 is formed in the upper part of the cover 3 and communicates with the inside of the cover 3 as shown in FIG. 4, the etching treatment tank 10 has a separate intake fan (not shown in the drawing). By drawing the air inside the cover (3) to discharge to the outside, since the residual solvent of the corrosion solvent scattered by the spray nozzle (2) is sucked out and discharged, water droplets of the corrosion solvent from the inner wall of the cover (3) The dropping prevents unnecessary corrosion and improves the working environment to enable a cleaner etching process.

In addition, as shown in FIG. 5, the cover 3 of the first washing tank 20, the first removing tank 30, the second washing tank 40, the second removing tank 50, and the third washing tank 60 is described. ) By forming a separate opening and closing hole 70 and inserting a removable opening and closing cover 71 so that the inside of the cover 3 is opened or closed by this, it is possible to check the working progress from time to time, or the corresponding position The feed roller (1) (1 ') and the injection nozzle (2) (2') of the replacement and repair is to make it easier to perform the operation.

In addition, as shown in FIG. 6, the barrier walls 13 and 13 ′ vertically placed at both ends of the collecting plate 4 of the etching treatment tank 10 have a corrosion solvent other than the etching treatment tank 10. Corrosion solvents leaking out of the barrier walls 13 and 13 'while preventing them from invading the area are again collected through a plurality of collection holes 12 formed below the barrier walls 13 and 13'. Will be introduced into the sump (6) through the collecting plate (4).

Therefore, the surface of the workpiece 100 introduced from one side of the apparatus is automatically discharged in a state where corrosion, washing, and removal of residues are completely completed according to the progress of each section, so that the polished surface and the corrosion surface are more clear. It is possible to realize high quality and mass production by speeding up production.
