The clam shell used in the present invention is a clam shell that takes out and discards the contents of the clam from fishing villages, restaurants, and food companies.

Since the shells are not used for other purposes except for tourism products by drawing colors or paintings on the surface of them, most shells are discarded as waste, and the amount used for tourism products is also very small. It belongs to the waste which cannot be seen as being.

The present invention is to collect and recycle the shells that are mostly discarded as waste as described above.

Therefore, there is no cost to buy shells at first, or very small cost of transportation cost, so the raw material cost is very low, and the cost of finishing materials can be greatly reduced due to cost reduction and waste. By recycling the shells corresponding to the environmental pollution can be prevented in advance.

The present invention has been started from the research to recycle the shells corresponding to the waste as industrial resources as described above. On the other hand, clam shells are also described as shells (貝殼) below, and many collected clam shells as described above may also be described as clam shells.

Therefore, the present invention is collected from the site where the shells are generated, the shells collected in this way is carried out to remove the foreign matter.

Foreign material removal of the shell can be done manually, but may be carried out by the following shell pretreatment step (T) for efficient treatment.

The shell pretreatment step (T) is not only may be carried out at the site where the shells are generated, but may also be carried out with the shells transported to the manufacturing plant, the shell pretreatment step (T) of the present invention shells It is a step to remove foreign substances in.

Therefore, the shell pretreatment step (T) of the present invention is carried out the shell washing process (T1).

The shell washing process (T1) is a process of removing foreign matters by first washing numerous shells by spraying the washing water.

Next, the shell water heating process (T2) is carried out, which is a process of heating the clam shell in water for 2-3 hours.

Therefore, when the shell is heated at 100 ° C. for 2-3 hours, the inner contents of the shell or any other foreign matter adhering to the shell surface will ripen and fall off.

In other words, if the contents inside the clam are fully cooked, the adhesion that clings to the clam is almost lost. In this state, when the water boils over the water, the water flows. By this water flow force, the inner content lost adhesion is to fall from the shell.

In addition, the shell is hot sterilized by boiling water, so that the sanitary shell material can be obtained.

Next, the shell foreign matter removal process (T3) is performed. This process is to inject the shell taken out of the hot water by the high pressure washing water so that the foreign matter which is not separated from the shell is separated and removed by the high pressure washing water.

After the shell foreign matter removal process T3 is completed, the shell drying process T4 is performed.

Shell drying process (T4) is to allow the conveyor (not shown) to pass through the drying furnace (not shown) and the shell shells are dried by moving the shell shell on the conveyor to pass through the interior of the drying furnace.

The drying temperature is not only to allow the shells to dry completely, but also to be secondarily sterilized at a temperature of 120-150 ° C. to allow drying for 2-10 minutes.

As the above-mentioned dried shells vary in size and thickness, thin and small ones are dried quickly for about 2-5 minutes, and large and thick ones should be dried for 5-10 minutes. .

Since the shell drying process (T4) only needs to dry the water, in some cases it may be dried by natural sunlight.

Next, the present invention is a good shell separation process (T5) is carried out.

The high quality shell separation process (T5) is a process of separating only good quality shells from which foreign matter is completely removed by hand, and when this process is completed, a high quality shell material is obtained.

Therefore, the present invention is to obtain a high-quality shell raw material, the charcoal is to buy and use the charcoal, it is carried out the manufacturing step (S) with the shell and the raw material.

Manufacturing step (S) of the present invention is first carried out a raw material grinding process (S1).

The raw material grinding process (S1) is to obtain a shell powder and a charcoal powder by grinding the shell material and the charcoal raw material, respectively, by a grinder. Since the mill is a known mill, detailed descriptions and drawings will be omitted.

The shell powder and the charcoal powder may be a powder having a particle size of 200-600 mesh, but preferably 200-400 mesh powder is used.

Next, the raw material mixing process (S2) is carried out, this process is a process of combining the shell powder and charcoal powder.

In the raw material mixing process (S2) and the shell powder and the charcoal powder together with the pressure-sensitive adhesive to combine them is added and mixed.

The pressure-sensitive adhesive is to be obtained by mixing 70% by volume of water, 30% by volume of glue on the basis of 100% by volume of the pressure-sensitive adhesive.

In the pressure-sensitive adhesive component used in the present invention, water is a natural ingredient, and not only is harmless to the human body, but also glue is a natural adhesive since it is similar to gelatin extracted from animal tissues such as leather, bone, fish, casein (milk solid material), and vegetables. It is possible to use an adhesive that is harmless to the human body.

Therefore, in the raw material blending process (S2), shell powder of 70-85% by volume, charcoal powder of 5-20% by volume and water and glue 10% by volume of the pressure-sensitive adhesive is mixed and mixed by a mixer. Since the mixer is a known device, detailed descriptions and drawings will be omitted.

After the raw material blending process (S2) is completed, the finishing material forming process (S3) and the finishing material drying process (S4) is carried out to produce a finished product as a finished product, and the following Table 1 shows various mixing ratios in the raw material mixing process (S2). After blending to complete the above manufacturing process is shown an example of testing the flexural strength.

Table 1

   division    Shell powder (% by volume)     Charcoal Powder (Volume%)     Adhesive (volume%)    Flexural Strength (㎏ / ㎠)   Example 1     80-85     5-10       10    42.3-45.8   Example 2     76-79    11-14       10    36.1-38.2   Example 3     70-75    15-20       10    32.5-34.0   Example 4     66-69    21-24       10    26.2-28.7   Example 5     60-65    25-30       10    23.6-25.7   Example 6     56-59    31-34       10    21.4-23.2   Example 7     50-55    35-40       10    20.4-18.4

The flexural strength is a flexural strength obtained by compressing a sample in a strength tester by preparing a sample having a width of 60 mm, a length of 30 mm, and a thickness of 6 mm.

Therefore, in order to have a desirable strength as a building finishing material 10, 70-85% shell shell powder, 5-20% charcoal powder and 10% by volume of the pressure-sensitive adhesive mixed with water and glue in the raw material mixing process (S2). It has been tested to have a flexural strength of at least 30㎏ / ㎠, but as a finishing material (10) used for ceiling or wall surface, as a finishing material (10) for air purification and humidity control, shell powder is 70-72% by volume, charcoal powder is 18-20% It is most preferable to mix and manufacture by the mixing | blending ratio of% and 10 volume% of adhesives.

When the blending is completed in the raw material mixing process (S2), the mixed finish material 10 becomes a kneaded state, but the dough state of the moisture state is not the state of the dough does not come out even when touched by hand.

Therefore, after the raw material mixing process (S2) is completed, the finishing material forming process (S3) is carried out.

In the finishing material forming process (S3), the molding die 20 is used as illustrated in FIG. The mold 20 is schematically illustrated to aid the understanding of the present invention, and in actual mass production, the finishing material 10 may be separated from the bottom or may have a structure that can be continuously produced.

Therefore, in the finishing material forming process (S3) is to be pressed to a high pressure by the compression member 30 of the compressor after the finishing material of the dough state is put into the molding die 20. Since the compressor is a known device, detailed drawings and descriptions thereof will be omitted.

The compression force of the compression member 30 is preferably to be compressed by a compression force of 300-450kg / ㎠f, but in some cases the compression force is added or subtracted according to the size, shape and thickness of the finishing material 10 to be molded It can be done.

Therefore, as the raw material of the dough state is compressed in the molding die 20, the thickness of the finishing material 10 is determined, as well as being molded in the same shape as the plate material, and is formed to be a high-density finishing material 10.

When the finish 10 is molded as described above, the finish drying process (S4) is then performed.

In this process, the finishing material 10 may be dried in a state embedded in the molding die 20 or may be dried with only the finishing material 10 by leaving the finishing material 10 from the molding die 20, but as a preferred drying method. It is preferable to leave the finish 10 from the mold 20 to dry only with the finish 10.

And in the finishing material drying process (S4) can be dried by loading a large amount of the finishing material 10 in the drying furnace (not shown), or the conveyor (not shown) in the state in which the finishing material 10 is raised in the drying furnace. It is also possible to allow the drying furnace to dry while the finish passes.

Therefore, the finish drying process (S4) is allowed to dry for 48-72 hours at a drying temperature of 10-23 ℃.

In drying the finish 10, if the drying temperature is high, cracks may occur in the finish 10, and if the drying temperature is too low, the drying time may be too long or freezing may occur, resulting in a poor product. It is best to let it dry for 48-72 hours at a drying temperature of -23 ° C.

Therefore, the drying as described above is to be dried for 48-72 hours at a drying temperature of 10-23 ℃ it is preferable to dry in a drying room, but in some cases may be dried at the same outdoor temperature as the drying temperature as described above have.

Therefore, it may be to be dried outdoors in the spring and autumn with the same temperature as the drying temperature, it is to be dried in the drying furnace in the summer or winter when the temperature is high.

Therefore, when the finishing material drying process (S4) as described above is completed, since the moisture (water) contained in the pressure-sensitive adhesive is almost evaporated, the shell powder and the charcoal powder are adhered by the glue component and hardened at the same time to produce a finished product.

Finishing material 10 manufactured as described above is made of a finishing material 10 having a rigid rigid state as in the conventional gypsum board, so as to obtain a finishing material 10 having strength that can be used on the ceiling or walls. do.

In addition, since the shell powder, which is the main raw material, has almost a white color, the finished finishing material 10 has a gray or light gray color close to the white color because the small amount of charcoal powder is included, so the ceiling or wall finishing material (10) It can have good color and quality.

And since the main raw material of the finishing material 10 is an inorganic shell component and a charcoal component, it is made of a flame-retardant material, and thus not only a finishing material 10 having a fire resistance that is not burned or burned well, but also a shell and char is inorganic, You will get a safe finish (10) that is completely free of harmful gases and does not burn out.

In addition, the shell component and the char component has almost no elastic deformation due to temperature or humidity changes, and thus has stability in dimensions such that there is little fear of gaps between the finishing material 10 or the finishing material 10 after construction.

And shells and char, which is a component constituting the finishing material 10 of the present invention has a low thermal conductivity, so that the efficiency of blocking hot and cold air outside in summer and winter is good, thereby obtaining a finishing material 10 having thermal insulation.

In addition, since the main component is a hard shell component of the inorganic has excellent sound insulation performance, it has a sound insulation that can create a quiet indoor environment by blocking various kinds of noise.

And since the finishing material 10 is manufactured with the main components of the shells to be discarded as already described above, it is possible to have an economical price to spread the cheaper finishing material (10).

In particular, the finishing material 10 of the present invention is not only harmless to the human body because it consists of a shell component and a charcoal component, which is one of natural products, so that the finishing material 10 itself exhibits indoor moisture control and air function. Done.

In other words, if the indoor humidity is high, the charcoal component of the finishing material 10 absorbs moisture, and if the interior is dry, the moisture contained in the charcoal component evaporates and is discharged, thereby having a function of automatically controlling the indoor humidity. .

In addition, since the charcoal has a deodorizing effect as already known, it absorbs odors and odors in the room, and thus the finishing material 10 having a charcoal component naturally exhibits an air purifying function.

Therefore, the present invention is not only harmless to the human body, but also to supply the finishing material 10 having the indoor moisture control function and the air purification function.

And the present invention can be manufactured by allowing the release member 11 having a fine hole in the middle portion of the finishing material 10, as shown in FIG.

The release member 11 may use a woven paper such as a piece of cloth with a lot of fine holes, and in some cases, a screen member made of metal may be used.

Therefore, when the finish material 10 is manufactured in a relatively thin thickness because the fine material of the release member 11 is filled with the finish material 10, the finish material 10 is not only prevented from falling into the debris state in advance and flexed. It can also play a role of increasing the intensity.

According to the above description, the present invention provides a building finishing material which is completely harmless to the human body and has an indoor humidity control function and an air purifying function while having insulation, fire resistance, sound insulation, economical efficiency, and dimensional stability, which are requirements for a typical building finishing material. Not only does it provide the effect to be obtained, but it also has the effect of providing a building finish that is completely free of harmful gases in the event of a fire.

In addition, by using the shells discarded as waste as the main raw materials, it promotes the prevention of environmental pollution and recycles the shell wastes into industrial resources, thereby bringing economic benefits as well as providing cost-saving finishing materials for external competitiveness. Provide effect.

In addition, the finishing material of the present invention is made of shells and charcoal corresponding to natural materials without heavy metals or synthetic fibers at all, even if the finish is crushed again when discarded, there is no harm to the soil at all to improve the soil Therefore, there is an effect that it provides a useful finish that does not cause any environmental pollution even at the time of disposal.

And since the present invention is to provide a finishing material mainly made of shells and charcoal, it is obvious that the present invention should be widely applied and protected unless the claims are greatly deformed.
