Description

[DESCRIPTION] [Invention Title]
PELLETS FOR CONSTRUCTION MATERIAL, PANEL FOR BUILDING MATERIAL AND BLOCK FOR ARTIFICIAL FISHING REEF USING THE PELLETS, AND METHOD FOR MANUFACTURING THEREOF [Technical Field]
<i> The present invention relates to pellets for construction material, a panel for building material and a block for artificial fishing reef using the pellets, and a method for manufacturing them, and more specifically to pellets for construction material, a panel for building material and a block for artificial fishing reef using the pellets, and a method for manufacturing them, which can not only reduce environmental pollution due to waste glass by using pellets, which are prepared by mixing additives that contain loess powder with discarded waste glass that has been processed into powder below a certain size, as material for manufacturing various construction material, but also provide materials that can replace the existing panels with building material and blocks for artificial fishing reef that had a possibility of causing environmental problems. [Background Art]
<2> Due to the development of a modern building technology, the car industry and the packing industry, the uses and the quantity of use of glass have increased geometrically, and consequently the quantity disposed of as waste glass has increased just as much. Meanwhile, as part of an effort to recycle waste glass, recycled glass is obtained through a purification process in which impurities are separated from collected waste glass, and the recycled glass is mixed to manufacture new glass products. But because there are technological limits to separation of impurities contained in glass waste, not all waste glass is recycled.
<3> Meanwhile, panels for building material frequently used as finishing material in modern buildings include various forms such as gypsum board, cement mortar and sandwich panel, and of these, gypsum board is used much more than the other forms of finishing material.
<4> Harmful effects by excessive use of such gypsum board include not only the problem that indoor environment cannot be maintained in a comfortable condition but also the problem that it is difficult to recycle wasted gypsum board. In particular, the gypsum board removed together with other building wastes in buildings has also a secondary problem that it could become a cause of polluting the environment around the building refuse dump all the more.
<5> Especially the hot wind of well-being that started blowing from advanced countries has also affected the change in building material for decorating or finishing indoor spaces. Namely, as the gypsum board that was used to finish or decorate the existing indoor space is substituted by finishing material made of wood or loess as raw material, the quantity of discarded gypsum board tends to increase as well. However, since gypsum board has an advantage that it can be purchased and installed at relatively low prices, it can be said that the overall quantity of use has not changed greatly.
<6> Meanwhile, in modern natural environment, due to serious contamination in coastal areas caused by the increase of carbon dioxide in the air and the rise of water temperature due to global warming, it has been quite long since marine algae in littoral zones were dispersed and were washed away in rocky coastal areas because of the behavior of biotic community and the lack of biological action.
<7> In order to prevent adverse effects of such a phenomenon on aquatic animals and plants, efforts are made to install porous artificial fishing reefs of various forms under water, but because most of the raw material for making artificial fishing reefs is cement, it has a problem that secondary contamination arises from erosion by sea water due to chemical components contained in cement. Especially, such secondary contamination brings about sudden multiplication of polyps, which are the larvae of jellyfish, so it is pointed out as a cause of hastening population imbalance of marine resources. [Disclosure] [Technical Problem]

<9> Another object of the present invention is to provide a panel for building material to be used as finishing material or decoration material of more environmentally-friendly buildings by using a new form of pellets for construction material.
<io> Yet another object of the present invention is to provide a block for artificial fishing reef to make the vegetation space of aquatic animals and plants more environmentally-friendly by using a new form of pellets for construction material.

[Mode for Invention]
<5i> Below will be described in detail the pellets for construction material using waste glass as a main component according to the present invention, the panel for building material using the pellets, the block for artificial fishing reef, and the method of manufacturing them with reference to the accompanying diagrams.
<52> Fig. 1 is a view for describing the process for manufacturing pellets for construction material according to the present invention, and Fig. 2 is a block diagram showing the manufacturing process of the pellets according to the present invention. Reference numeral 100 marked in the drawing shows pellets for construction material. A pellet 100 for construction material spherical shape is roughly spherical in shape and has a size of 2-50 mm diameter. Meanwhile, in the course of description below, the name of pellets 100 for construction material can be contracted to pellets 100.
<53> The main raw material used in manufacturing the pellets for construction material is waste glass discarded from buildings, cars and packing containers. Waste glass collected for use in manufacturing pellets 100 for construction material goes through an impurities separation process for demolding impurities and a washing process and then goes through a crushing process through crusher, etc. to be first made into powder. Pulverized waste glass is ground by grinder in the raw material preparation step to be made into powder with a grain size of 200 mesh or less, which is a condition convenient for carrying out the present invention.
<54> In the raw material preparation step, loess powder, which is another raw material of pellets 100 for construction material, is ground by grinder to a grain size of 200 mesh or less. For reference, in the process for matching the grain size of powder, the process of passing powder through a screen having the relevant grain size may be carried out.
<55> Waste glass powder and loess powder pulverized through the grinding process are mixed with another raw material, sodium silicate. At this time, water is added in the mixing process so that waste glass powder and loess powder are mixed uniformly. The raw material mixing step for manufacturing pellets 100 for construction material can be divided into a dry mixing step in which waste glass powder 80-90 weight % and loess powder 3~5 weight % are put in a Hobart mixer for dry mixing and a wet mixing step in which dry-mixed waste glass powder and loess powder are mixed with sodium silicate 3~5 weight % and water 4-10 weight %. Especially, it is preferable to carry out the dry mixing step by the Hobart mixer for about 20 or more minutes and carry out the wet mixing step, in which water is added, for about 15-20 minutes.
<56> The mixed raw material that is mixed in the raw material mixing step goes through an agitation step by agitator to knead it to form sludge.
<57> The mixed raw material agitated like above goes through an injection step, in which it is put in a molding flask having a predetermined shape and injected in a form having a predetermined thickness and length. The injection substances injected in a long length in the injection step are hardened after a predetermined time has passed and are cut to a short length through a cutting step. The injection substances cut like this go through a molding step so as to have a nearly spherical shape.
<58> In the molding step, the injection substances may be molded by an automated machine such as a pill maker that is used to manufacture medicine, or the injection substances cut to a small size may be put into a separate metal container and then shaken for a predetermined time to form them in a suitable shape. As the injection substances that have gone through such a molding process are made into a nearly spherical shape, the chemical properties of the pellets are not changed but the physical properties such as the shape and strength of the pellets are changed to be advantageous for use as building material or civil engineering material. The pellets 100 after finishing the molding step have a size within 2-50 mm according to their use.
<59> Especially, the pellets 100 that were already made into spherical shapes by going through the aforementioned molding step can be manufactured or produced by baking in a separate baking step according to their use. In the baking step, the pellets molded to small sizes are baked in a high- temperature furnace, and it is preferable to set the temperature of the furnace at 800-900° C.
<60> The method of manufacturing pellets described above is just one embodiment for manufacturing pellets 100 for construction material, and the pellets 100 for construction material according to the present invention can be manufactured also by more various ways based on the aforementioned method. Namely, for manufacturing the pellets 100, starting from kneading waste glass powder 80-90 weight %, loess powder 3-5 weight %, sodium silicate 3-5 weight % and water 4-10 weight % until molding into nearly spherical shapes, it is not necessarily to apply the method the same as the aforementioned embodiment .
<6i> Meanwhile, the pellets 100 for construction material manufactured like above can be used as major material in the process of producing a panel 200 for building material or in the process of producing a block 300 for artificial fishing reef. Of course, it is not that the pellets 100 for construction material are supplied only to produce the panel 200 for construction material or the block 300 for artificial fishing reef. Below will be described the panel 200 for building material and the block 300 for artificial fishing reef.
<62> First, referring to Fig. 3 and Fig. 4, the panel for building material for which pellets 100 are used and its manufacturing method will be described in more detail. Fig. 3 is a view showing the production process of a panel for building material using the pellets for construction material, and Fig. 4 is a block diagram showing the manufacturing process of the panel for building material according to the present invention. The reference numeral 200 marked in the drawing shows a panel for building material, and the panel 200 for building material is manufactured by using waste glass as main raw material produced in the same way as the pellets 100.
<63> As shown in Fig. 3, the panel 200 for building material is made in a structure of three layers, and the middle layer is a pellet layer 202 which is made of a plurality of pellets 100 for construction material to a predetermined thickness. At the bottom and top of the pellet layer 202 are form a lower hard layer 204 and upper hard layer 206, respectively.
<64> The lower hard layer 204 and upper hard layer 206 are formed by molding to a predetermined thickness, after going through a baking process, the main raw material waste glass powder mixed with loess powder, sodium silicate, caustic lime, calcium carbonate, sodium hydroxide, ferrite and water.
<65> The lower hard layer 204 and upper hard layer 206 are prepared by mixing waste glass powder 60-75 weight %, loess powder 4-6 weight %, sodium silicate 6-10 weight %, caustic lime 2-3 weight %, calcium carbonate 2-3 weight %, sodium hydroxide 3-5 weight %, ferrite 3-5 weight %, and water 5-8 weight %. Meanwhile, the pellets 100 that form the pellet layer 202 are prepared by mixing waste glass powder 80-90 weight %, loess powder 3-5 weight %, sodium silicate 3-5 weight % and water 4-10 weight %, as mentioned above.
<66> The waste glass powder and loess powder mixed with the mixed raw material to form the lower hard layer 204 and upper hard layer 206 are pulverized to a grain size of 200 mesh or less, and ferrite is pulverized to a grain size of 250 mesh or less.
<67> The process for manufacturing the aforementioned panel 200 for building material goes through a hard layer raw material mixing step, agitation step, mixed raw material lamination step, baking step and demolding step, as shown in Fig.4.
<68> The hard layer raw material mixing step can be divided into a dry mixing step and wet mixing step. The dry mixing step is the process in which the main raw material waste glass powder is mixed with loess powder, ferrite powder and calcium carbonate, and the wet mixing step is the process in which sodium silicate, sodium hydroxide, caustic lime and water are added to the mixed raw material that was mixed in the dry mixing step. The hard layer mixed raw material mixed in this raw material mixing step is made of waste glass powder 60-75 weight %, loess powder 4-6 weight %, ferrite 3~5 weight %, calcium carbonate 2-3 weight %, sodium silicate 6-10 weight %, sodium hydroxide 3-5 weight %, caustic lime 2-3 weight % and water 5-8 weight %. At this time, the waste glass powder and loess powder mixed with the raw material to form the lower hard layer 204 and upper hard layer 206 have the grain size of 200 mesh or less, while the ferrite has the grain size of 250 mesh or less.
<69> The hard layer mixed raw material mixed in said raw material mixing step goes through the agitation step so as to be agitated for a predetermined time. And a step for drying the raw material and a step for pulverizing the dried mixed raw material again may be carried out additionally so as to remove the parts flocculated or coagulated between raw materials by the cohesive force of sodium silicate and water in the agitation step.
<70> The raw material lamination step for laminating the mixed raw material in the molding flask 210 provided separately can be divided into a lower hard layer lamination step for laminating the hard layer mixed raw material from the floor of the molding flask to a predetermined height for the lower hard layer to be formed, a pellet layer lamination step for laminating the pellets 100 for construction material manufactured separately by using the waste glass as main raw material on the top of the lower hard layer 204, and an upper hard layer lamination step for laminating the hard layer mixed raw material to a predetermined thickness to form an upper hard layer 206 on the top of the pellet layer 202.
<7i> It is preferable to use the pellets 100 for construction material that were prepared by mixing waste glass powder 80-90 weight %, loess powder 3~5 weight %, sodium silicate 3~5 weight % and water 4-10 weight %, as mentioned above.
<72> In the baking process, the molding flask, in which hard layer mixed raw material and pellets are laminated to form the lower hard layer 204, the pellet layer 202, and the upper hard layer 206, is put in a high-temperature furnace 400 to be baked. In the process, the temperature inside the furnace is maintained within 800-900° C. When the temperature of the furnace reaches about 700° C or above, the glass component contained in the hard layer mixed raw material starts melting and the mixed raw material in powder condition has its physical properties changed so a phenomenon of sticking together occurs. Also, a phenomenon, in which part of the hard layer mixed raw material located on the top of the pellet layer 202 to form an upper hard layer flows down to the pellet layer 202 and penetrates into the space between pellet 100 and pellet 100, occurs.
<73> Meanwhile, the loess powder will have its physical properties changed if the temperature of the furnace 400 becomes 1000° C or higher, but since the temperature of the furnace was set to be maintained within 800-900° C, there will be no change in the physical properties of loess powder. Accordingly, waste glass powder will melt into part of air gaps between loess powders naturally, so eventually the mixed raw material that was in a phase of powder or liquid forms one body called a panel 200 for building material.
<74> With the temperature of the furnace that was heated to high temperatures in the baking process dropped to 100° C or lower, the work manager takes the molding flask from the furnace, and carries out the demolding process in which the finished panel 200 for building material is separated from the molding flask 210. The panel 200 for building material demolded from the molding flask is inspected for a predetermined quality, etc. and shipped as finished product.
<75> The panel 200 for building material manufactured like above has the characteristics and advantages as follows.
<76> 1) Its excellent sound-proof effect makes it possible to solve a considerable part of the problem of privacy violation due to noises between floors of building.
<77> 2) It is possible to prevent new house syndrome and atopic diseases due to misuse of gypsum board.
<78> 3) Its fire resistance makes it possible to prevent fire breaking out due to the use of sandwich panel.
<79> 4) Whereas the existing cement, gypsum board and sandwich panel have a high possibility of polluting the environment when building waste is generated, the panel for building material according to the present invention is harmless to the human body thanks to its environmentally-friendly porous material and has a value of not causing environmental pollution through the use of waste resources.
<80> 5) It can be expected that international competitiveness is enhanced in the building market which is a huge consumer market and the living conditions of residents and office users are improved.
<8i> Next, referring to Fig.5 and Fig. 6, the block for artificial fishing reef using pellets 100 and method for manufacturing the same will be described in more detail. Fig. 5 is a view showing the production process of a block for artificial fishing reef using pellets for construction material, and Fig. 6 is a block diagram showing the manufacturing process of the block for artificial fishing reef according to the present invention. The reference numeral 300 marked in the drawing shows a block for artificial fishing reef, which is manufactured by through process in which the pellets for construction material 100 made as described above are put in a separate molding flask and baked.
<82> The aforementioned block 300 for artificial fishing reef is manufactured by using pellets 100 for construction material that were molded to a predetermined size after mixing the waste glass powder as a main component with loess powder, sodium silicate and water and kneading it to form sludge and agitating, thereby it is possible to provide more environmentally-friendly artificial fishing reef. The raw material used to manufacture the block 300 for artificial fishing reef is prepared by mixing waste glass powder 80-90 weight %, loess powder 3-5 weight %, sodium silicate 3-5 weight % and water 4-10 weight % as mentioned above.
<83> Up to a certain step in the process of producing the block 300 for artificial fishing reef, the steps described in the method of manufacturing the aforementioned pellets 100 are carried out likewise. Of course, in the case of using the already-manufactured pellets 100 for construction material, it is possible to greatly reduce the number of steps for manufacturing the block 300 for artificial fishing reef. Namely, it is possible to omit the basic steps such as the dry mixing step, wet mixing step, agitation step, injection step, cutting step and molding step which are necessary for manufacturing the pellets 100.
<84> To manufacture the block 300 for artificial fishing reef without using the already-manufactured pellets 100, the steps necessary for molding the block as well as most of the steps that were already described as a method for manufacturing the pellets 100 should be carried out. Namely, with the pellet forming step that is necessary for manufacturing the pellets 100 such as the dry mixing step, wet mixing step, agitation step, injection step, cutting step and molding step finished, the lamination step in which plurality of pellets 100 molded to be nearly spherical in shape are put in a molding flask 310, the baking step in which the molding flask with the pellets 100 laminated therein is put in a high-temperature furnace 400 to be baked, and the demolding step in which a baked block product is separated from the molding flask should be additionally carried out. <85> In the molding step of the pellet forming step, as described before, the injection substances cut to a predetermined size are put in a pill maker, and it is operated for a predetermined time; or the injection substances are put in a metal container having a predetermined volume and the metal container is shaken for a predetermined time. Through such a process, they are produced in a form near to a required sphere.
<86> In the baking step for baking the block 300 for artificial fishing reef, the temperature inside the furnace is set to be maintained within 800-900° C. Meanwhile, although loess powder would have its physical properties changed if the temperature of the furnace 400 reached 1000° C or higher, since the temperature of the furnace is set to be maintained with 800-900° C, there will be no change in the physical properties of the loess powder. Accordingly, waste glass powder will melt into part of air gaps between loess powders naturally, so eventually the mixed raw material that was in a phase of powder or liquid forms one body called a block 300 for artificial fishing reef.
<87> With the temperature of the furnace that was heated to high temperatures in the baking process dropped to 100° C or lower, the work manager takes the molding flask from the furnace, and carries out the demolding process in which the finished block 300 for artificial fishing reef is separated from the molding flask 310. The block 300 for artificial fishing reef deraolded from the molding flask is inspected for a predetermined quality, etc. and shipped as finished product.
<88> The block 300 for artificial fishing reef manufactured like above has the characteristics and advantages as follows:
<89> 1) It enables the creation of porous artificial fishing reef in coastal sea areas which provides a healthy habitat for feeding, spawning and growth of a variety of marine life.
<90> 2) It is possible to maintain continuous fishing reef functions through formation of submarine forest using blocks to which algae are adhered artificially or periodical provision of a new surface substrate which was impossible in the existing monolithic artificial fishing reef.
<9i> 3) It displays a functional effect as fishing reef for initial formation of submarine forest in the coastal area where algae are being washed away by melting of sea alga or strong external force.
<92> 4) Whereas the existing porous concrete or industrial waste blast furnace slag has a high possibility of secondary pollution of environment, the block for artificial fishing reef according to the present invention uses waste resources that are environmentally friendly and are harmless to the environment, so it has a value of environmental-friendly creation that reduces marine pollution.
<93> 5) By applying the block for artificial fishing reef of the present invention, it can be expected that economic competitiveness is enhanced by using fishery and marine resources and the living standard of fishermen is improved by their increased real income. [Industrial Applicability]
<94> As described above, according to the present invention, it is possible to manufacture and supply products such as environmentally-friendly panels for building material and blocks for artificial fishing reef by using waste glass collected from buildings, cars, beverage containers, etc., so it has a big advantage that they can substitute products that use gypsum, concrete or cement as main raw material.
<95> Another big advantage of the panel for building material according to the present invention is that it is excellent in sound-proof performance as it uses waste glass as main raw material and it can cut off noise transfer between spaces of buildings better than gypsum board.
<96> Moreover, the block for artificial fishing reef according to the present invention has an advantage that it can be very helpful to vegetation of aquatic plants because it can reduce the adverse effects of concrete or cement that was used to form existing artificial fishing reefs.
<97> Although the present invention has been described in connection with the exemplary embodiments illustrated in the drawings, it is only illustrative. It will be understood by those skilled in the art that various modifications and equivalents can be made to the present invention. Therefore, the true technical scope of the present invention should be defined by the appended claims.
