Abstract

PROBLEM TO BE SOLVED: To improve a whole coating process by adopting a sand-blasting method in place of a process comprising polishing by sand paper, under coating, middle coating, and finish coating being implemented as a method for coating a wooden product. SOLUTION: In coating a wooden product, fine powder having a grinding capacity such as fine sand of 80 minus mesh, stone powder, metal powder, plastic powder, powder of hard seeds and shells of plants, and shell powder is ejected at a high pressure to a substrate to be ground to cut/grind conduits and tree fibers in grain or tree feathers or resin components and simultaneously to grind tree feathers adherent to the surface of the substrate clearly to form uniform, minute recessed holes like the surface of ground glass so that the packing of a filler in the grain is facilitated completely, and the substrate can be colored uniformly and clearly.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for coating a wide variety of wood products in the woodworking industry.

[0002]

2. Description of the Related Art Sandpaper is used as a conventional means of coating wooden products without exception for smoothing and polishing of fabrics and intermediate coatings. Although there is room for dissatisfaction, it has not yet been resolved.

[0003] As the current woodwork coating, there is polishing of the wood material of the object to be coated in the process, and the flatness is smoothed with sandpaper having a particle size of about 100 to 400 mesh to physically improve the adhesion of the paint.

[0004] In the wood, countless elongated small holes, which are commonly called wood grain, are developed on the surface. In order to fill the grain evenly with the paint, a sealing step is required in which the resin and the solvent such as tono powder, calcium carbonate and the like and the solvent are mud-like and the recessed portions are treated and smoothed.

[0005] In order to improve the adhesion of the paint and to ensure the beautification of the paint film, an undercoat is applied next to the sealing, and then the paint film is thickened to ensure a smooth mirror surface with a finish paint after the product. In the intermediate coating step, an intermediate coating having good abrasive properties is used.

Various paints are used as a top coat as a finishing step according to the purpose.

[0007]

SUMMARY OF THE INVENTION In view of the above situation, it is an urgent task of the present invention to pursue defects in sandpaper polishing and to reform them. It is a method that is established as a method

[0008]

Based on the above considerations, in order to eliminate defects caused by sandpaper polishing, sand, sand powder, metal powder, plastic powder, hard plant nuts and the like having a particle size of less than 80 mesh are required. A fine powder with a grinding ability such as shell powder, shell powder, etc. is sprayed on the target fabric at high pressure to cut and grind the duct wood fiber or wood wool and resin in the grain, and at the same time, to form a uniform micro concave like a glass surface on the fabric surface. This makes it easy to completely fill the grain with the filler, and enables uniform and clear dough coloring. This high-pressure spraying method of hard fine particles is known as a so-called sand blast method.

In order to further elucidate the polishing defects caused by the sandpaper, all the irregularities of the cloth are smoothed by repeated polishing of the paper, but the fine particles of the paper gradually lose the acute angle and the grinding ability is deteriorated. The inner surface of the wood is covered with thin wood fiber, wood wool and resin, etc., which cannot be cut off by grinding paper, and the wood feathers in the fabric are pressed flat against the fabric without being cut. The filling agent is not completely filled in the concave portion, the air becomes full, and if the paint is applied, the air has no destination, the solvent of the applied paint evaporates and the viscosity increases. When the coating film is formed, the filled air starts to rise and breaks the coating film and escapes to the atmosphere.Small dents are formed in the coating film, and some remain as bubbles on the surface. This is a phenomenon that is noticed as a coating neck that occurs at various places on the surface of the object to be coated.

As described above, by employing the "sand plast method", defects caused by sandpaper can be completely eliminated, and fine particles are sprayed at a high pressure, so that fluff such as tree hair and reverse hair on the wood surface can be cut finely. The hard paper is blown away with the hard fine particles and the paper does not cut and is pressed and laid down, without any discomfort, the hair that interferes with painting is completely removed, and the fine particles can be recycled and all polishing defects with existing paper are eliminated. Things.

Regarding the sandpaper, even if new paper having a cutting force is used without taking into account the cost burden, the wood fiber, wood fluff and resin in the grain are cut in accordance with the sandplast method and simultaneously with high pressure air. All the cut wood wool is blown away, and the small dents in the grain are cleaned thoroughly, making it easier to fill the filler and leaving no air pockets in the grain after the closure. Can be.

According to the sandplast method at the same time as the cleaning of the grain, the wood-coated material is made of fine particles by spraying fine particles to form microscopic indentations on the entire surface, which are invisible to the naked eye. Is a finer surface than the surface of the ground glass, and does not hinder any smooth coating at all, but rather the coating gives a very good adhesion to the object to be coated and gives good results. Thus, since the microholes uniformly cover the entire surface like a ground glass, the coloring agent is sucked very evenly when applying color to the coated wood, compared to the surface pressed and polished with sandpaper. This makes it possible to bring out a remarkably vivid color tone, and enables stunning coloring without any spots.

[0008]

Based on the above considerations, in order to eliminate the defects caused by sandpaper polishing, sand, sand powder, metal powder, plastic powder, hard plant nuts and the like having a particle size of less than 80 mesh are required. A fine powder with grinding ability such as shell powder and shell powder is sprayed onto the target fabric with high pressure to cut and grind the duct wood fiber or wood wool and resin in the grain, and at the same time the fabric surface is ground with sandpaper with weak grinding power.
Intended to make a uniform minimum concave hole such as Sri glass surface deprived of wood fluff, which is crimped to the dough surface, makes it possible to fully easily and to and uniformly crisp dough colored Metome replenishing the grain without is there. This high-pressure spraying method of hard fine particles is known as a so-called sand blast method.

In order to further elucidate the polishing defects caused by the sandpaper, all the irregularities of the cloth are smoothed by repeated polishing of the paper, but the fine particles of the paper gradually lose the acute angle and the grinding ability is deteriorated. The inner surface of the wood is covered with thin wood fiber, wood wool and resin, etc., which cannot be cut off by grinding paper, and the wood feathers in the fabric are pressed flat against the fabric without being cut. in sealer without being completely filled in a concave hole, now the air is filled, if Hodokose paint air is neither discharged destination, solvents painted coating evaporates, increasing the viscosity When the coating film is formed, the filled air starts to rise and breaks the coating film and escapes to the atmosphere.Small dents are formed in the coating film, and some remain as bubbles on the surface. This is a phenomenon that is noticed as a coating neck that occurs at various places on the surface of the object to be coated.

As described above, by employing the "sand plast method", defects caused by sandpaper can be completely eliminated, and fine particles are sprayed at a high pressure, so that fluff such as tree hair and reverse hair on the wood surface can be cut finely. The hard paper is blown away with the hard fine particles and the paper does not cut and is pressed and laid down, without any discomfort, the hair that interferes with painting is completely removed, and the fine particles can be recycled and all polishing defects with existing paper are eliminated. Things.

[0011] In addition, even if a new paper having a cutting force is used without taking into account the cost burden, it is not possible to remove the wood fiber, the fluff, and the resin in the grain.
No. However wood, hair and others that have been cut by the cutting and high-pressure air at the same time if follow example to the method of sandblasting method is all blown off grain small concave hole is clean cleaning, grain after the eye stop together makes it extremely easy filling of the Metomezai There is no need to worry about leaving an air pool inside.

[0012] Although cleaning a wood coating object, according to the sandblasting method at the same time the wood grain is entirely uniform fine concave holes invisible in microns by spraying the particles by sandblasting made, these small concave holes Is weak in grinding power
Pressure on the fabric surface without grinding
It is a surface that is even finer than the surface of the pickled glass by removing the wood fluff that has been worn, without any hindrance to the smooth coating at all, and rather the paint has extremely good adhesion to the object to be coated Is to give. Thus, the microholes uniformly cover the entire surface like a ground glass, so that when coloring the wood to be coated, the colorant is sucked in evenly and compared to the surface pressed and polished with sandpaper. This makes it possible to bring out a remarkably vivid color tone, and makes it possible to achieve excellent coloring without any spots.
