The present invention relates to a method for producing a foamed ceramic panel to enable a simple and efficient manufacturing of a foamed ceramic panel to be usefully used for various building materials.

As is well known, there have been many studies on effervescent inorganic compounds, but there are no effervescent ceramic panels that can be effectively used as building materials using such effervescent inorganic compounds. There is almost nothing.

Therefore, in the present invention, in the manufacture of foamed ceramic bodies (or foamed ceramic panels) foamed by foaming the foamed inorganic compound at high temperature, the present invention is more focused on the characteristics of the foamed ceramics. It is intended to be manufactured in a shape and size suitable for building materials and at the same time to provide a large amount at a very low price, to further improve the patent application No. 94-4554.

On the other hand, Patent Application No. 94-4554 has many advantages and efficiencies in its own way, but in the manufacture of the prefabricated container for manufacturing the foamed ceramic panel, the number of shelf plates required for manufacturing the prefabricated container is, of course, such a Since the shelf plate is generally expensive, the manufacturing cost of the foamed ceramic panel manufactured using the shelf plate is naturally increased, and thus, it is expected that some difficulties are expected to spread the expanded ceramic panel, which can be usefully used for various building materials. There is a problem that excessive manpower is required to manufacture the container, and in particular, many processes issued by foaming the ceramic body are displayed on the outer surface of the foamed ceramic panel. It was not a lot.

The present invention has been drawn in consideration of such various matters, and the brick or tile material is put into a refining machine, and the relatively thin and wide plate is discharged and then set in a mold to form a rectangular box, and the foamed inorganic compound in the rectangular box. By firing and foaming, the foamed ceramic panel with integrated rectangular box and foamed inorganic compound is manufactured so that mass production of foamed ceramic panel can be made efficiently, and productivity improvement through automated process and significant reduction of manufacturing cost The purpose of the present invention is to provide a low-cost supply, and thus to be useful and widely used for various building materials such as roofing materials, interior and exterior materials. same.

Ready

First, the base material for brick or tile and the foamed inorganic compound 10 are provided. Herein, the expandable inorganic compound (10) is fluorite, feldspar, feldspar, clay, pottery stone, clay, silicon carbide, dolomite, silica, bentonite, zinc, zirconium, barium lactate, apatite, shale, bone ash, talc, quartz, In addition to pure inorganic compounds such as calcite and fluorspar, fly ash, martha dust, slate rock, waste glaze (remaining glaze from a ceramic factory), aluminum ash (AL ash) and sludge Waste material), a mixture of extracting industrial waste inorganic compounds such as stone powder at a predetermined ratio, and referring to one specific example, slate rock 30%, fluorite 30%, feldspar 10%, feldspar 5%, sludge Powder material mixed with 3%, clay 1.7%, and 0.3% silicon carbide is an expandable inorganic compound (10) to be directly put into the box 8 to be described later.

On the other hand, the individual substances constituting the expandable inorganic compound (10) and its composition ratio can be carried out in a variety of ways, and the components and composition ratios are slightly different composition even if the odor removal, soundproofing, sterilization, etc. The action and effect of the ceramics are not only similar to each other, but are not the main part of the present invention. Therefore, detailed descriptions of the components of the expanded inorganic compound (10) and the composition ratio thereof will be omitted.

1st process (the process of making your body)

This is to construct the base material (1) using a very low-cost brick material or tile material, such a material (1) is usually formed in the form of flour dough with a powder, it is a general Description is omitted.

Second process (discharge and cutting process of your body)

The base 1 prepared in the first step is placed in the refining machine 2, and discharged to the base plate 4 having a relatively wide plate shape, and then cut into a predetermined length through the cutting device 3.

On the other hand, when manufacturing the non-shaped base plate 4 (which is the same as saying that the outer surface of the foamed ceramic panel, which is the finished product of the present invention) is as described above, the surface portion of the base plate 4, as described above In order to engrave the pattern on each side, the pattern plate is passed through a separate stamping roller that forms a pattern shape before passing through the cutting device 3, and then the pattern is cut to cut the side and the bottom of the plate plate 4. It is to be imprinted naturally on the part, and thus the outer surface part of the foamed ceramic panel 12, which is a finished product according to the present invention, is to be reproduced with a beautiful and stylish pattern.

3rd process (square box formation process)

After placing the base plate 4 cut in the second process on the lower mold 21 through the transfer conveyor 15 to form a rectangular box 8 by setting the upper mold 22, the lower mold The structure of (21) is to allow the four sides of the side plate (21a) by using the hinges 23 and the like on each side of the base plate 21 'of the square so as to be retracted or unfolded as necessary, but the lower mold (21) ) Is placed in the unfolded state of the holding plate (4) cut to a certain length, the upper mold 22 is set, and then the side plate 21a of the lower mold 21 is opened, the rectangular box (8) is formed Will be.

In addition, the bottom surface of the upper mold 22 is slightly convex, so that the rectangular box 8 can be manufactured more smoothly, but by applying oil to the upper and lower molds from time to time, the failure rate of the box 8 itself is also reduced. This would be preferable.

In addition, since the bottom surface of the upper mold 22 is convex, the rectangular box 8 is also formed with a relatively thin bottom, and each corner portion is thicker so that the manufacture of the rectangular box 8 may be more desirable. do.

In addition, in this process, the upper and lower molds 21 and 22 can be operated by an automated facility, and the box box 8 can be formed also by semi-automatic and manual operation.

4th process (drying process)

Put the rectangular box (8) completed in the third step in the drying furnace (7) and dried for about 312 hours in the temperature range of about 150 ℃ 350 ℃, the temperature changes with the passage of the rise and fall repeatedly Of course.

5th process (rebuilding process)

The reason why the drying time is so wide is that the first dried rectangular box (8) through the fourth process is put in another drying furnace (7 ') and re-dried for about 524 hours in the temperature range of about 9001200 ° C. This is because when the thickness of the rectangular box 8 is very thick, the drying time can only be so long.

In addition, the reason for causing the blind box 8 to be re-dried again is that the foamed inorganic compound 10 described later in the state where the moisture content flow rate of the primary dried box 8 is high (about 15% or more). This is because a crack (carck) is formed in the wall surface part of the rectangular box 8 when it is put inside the rectangular box 8 and fired and foamed.

In addition, the reason for cracking is that when the foamed ceramic panel 12, which has completed foaming at a high temperature, is taken out to the outside, the inner and outer walls of the box 8 are different from each other due to a sudden temperature drop. The outer wall surface of (8) is quenched by the influence of ambient temperature inside and outside 3040 ° C, and the tissue itself tries to shrink (contract), while the inner wall surface tries to maintain the stretched (expanded) tissue as it is due to the internal high temperature effect. The tendency is due to the conflicting friction of the two properties, and this phenomenon is not only worse when the water flow rate of the box (8) is higher (ie, less dry), and once the product is cracked, it becomes less commercial. Inevitably, the construction decision according to the present invention is very important.

Therefore, if the thickness of the rectangular box (8) is not thin, but thick, if the crack (Crack) rate is high, it is preferable that the rectangular box (8) to lower the water content through the redrying process, it is preferable, and the moisture content is low The lower it is (no cracking if water content is below 78%), the lower the risk of cracking. In addition, although the drying process is described later, the firing environment (temperature, time, etc.) may vary depending on the size of the foamed ceramic panel 12. Thus, the water content of the box 8 is only a matter of the fourth drying process. It would be smooth to be terminated in the rebuilding process of 5.

6th process (firing process)

In the fifth process, the coarse rectangular box 8 is again conveyed by the conveying conveyor 15 'and then reaches a predetermined point. The foamable inorganic compound 10 is formed by the automatic feeding machine 9 on the upper part of the conveying conveyor 15'. Automatically insert it, but put it about 2/3 of the height of the rectangular box (8) and evenly spread it.

Then, the rectangular box 8 is gradually loaded by a carrier such as a trolley and pushed into the firing furnace 11 by several dozens, and then fired and foamed at a temperature range of 11001500 ° C. The box or box 8 is pushed one by one for a predetermined time, and another box 8, which has been pushed into the kiln 11 in order, is already foamed and fired to be discharged one by one. You may.

When the fire is fired while the box 8 is inserted into the firing furnace 11, the fire is directly transferred to the box 8, and at the same time, heat is directly transferred to the foamable inorganic compound 10, and the boiling point starts to gradually heat. When foaming starts at once (the foamable inorganic compound is a boiling point, the foaming point is a boiling point), the foamable inorganic compound (10) is formed integrally with the box body (8), thereby completing one foamed ceramic panel (12) Lose.

However, it should be noted here that the box 8 is completely integrated with the foamable inorganic compound 10 at the time of foaming, but the box 8 is itself only fired and is not foamed.

Therefore, the upper surface of the completed foam ceramic panel 12 is in a foamed state with a slight uneven surface, but the remaining surface is very smooth, but also a strong state.

On the other hand, the pigment may be mixed with the expandable inorganic compound (10) and put into a rectangular box (8) to be fired. In this case, only the upper surface of the expanded ceramic panel 12 may be expressed in various colors, but the expanded ceramic panel 12 may be divided into several parts. In the case of cutting with a color, it is considered that the color is expressed for each surface of the cut panel 12.

The finished foamed ceramic panel 12 is formed of a rectangular foamed ceramic plate having the expected thickness and size originally intended as shown in FIG. 4, and used as interior / exterior material of interior wall or ceiling. It can also be used for other building materials such as roofing and insulation.

In addition, it may be used directly, but as will be described later, the reworking process may be used to increase the decorative effect or to diversify or enhance the use.

7th process (reprocessing process)

The foamed ceramic panel 12, which has undergone the sixth process, can be used as a commodity itself, but in the case of the foamed ceramic panel 12 foamed in consideration of separation and cutting from the beginning, separation and cutting to a desired size and thickness. Afterwards, the outer surface is coated with glaze and then refired to improve or diversify the product. It is a matter of course that the method of refiring after treating the glaze or the like is possible even after finishing the sixth process, that is, without removing and cutting the foamed ceramic panel 12.

As such, the birth of the foamed ceramic panel 12, which has undergone a firing process or a reprocessing process, is expected to result in a breakthrough development of building materials. That is, when used as a ceiling plate, partition unit, exterior wall material, roof material, flooring material, insulation, hot-season aggregate, building beauty wall, sound-absorbing plate, brick, tile, anti-earthquake vegetation plate, wall board, fireproof plate, etc. The foamed ceramic panel itself is made of concrete or other materials, which is very light compared to the shaft material or civil engineering material, which makes it easier to transport and construct, and secondly, the body and foam ceramic are integrated The strength of the structure is also considerable, and the set material does not benefit from the properties of the existing building materials, while the foam ceramic panel according to the present invention is sprayed from the foam ceramic panel 12 in addition to the activation of the biorhythm. Due to the radiation energy of far-infrared rays, etc., the comfort of interior space is accompanied by the effects of aging, self-cleaning and resonance. You will be able to enjoy it.

In addition, as shown in FIG. 5, when the foamed ceramic panel 12 is cut into several sheets, both surface portions 5 (a) of each cut panel 12 are also referred to, or surface portions 5 (b) are also referred to. The particulate matter 14 may be applied.

The particulate matter 14 is placed in the kiln and the calcined material 18 is heated and calcined at a temperature of about 300 ° -600 ° C. for about 30 minutes, and then put into a grinder to be finely pulverized to 325 mesh or more, and this is again The inorganic binder 19 is mixed at a ratio of about 3: 7. Therefore, this is applied to the surface of each panel 12 at about 20100 mu and dried, so that not only various building materials but also especially interior and exterior materials of furniture may be used. It can also be used as an external board, preventing growth and breeding of various germs inhabiting interior spaces or furniture, removing moisture and odors, and reducing the amount of flame in case of fire (foamed ceramic panels coated with fine particles). Silver hardly melts unless the temperature of the flame is higher than 1000 ℃).

As described above, the foamed ceramic panel 12 having the desired size and thickness may be easily and easily obtained in large quantities through the sixth or seventh processes in the first process.

Therefore, unlike the conventional method, which requires careful attention and complicated work process, the present invention not only reduces manpower but also greatly increases productivity, and in particular, directly applies heat to the rectangular box (8) to increase the efficiency of thermal energy, thereby significantly reducing energy consumption. In addition, the outer wall surface of the foamed ceramic panel 12 is not in a foamed state, but because it is a brick material or a tile material as it has the advantage of having a rigid strength.

After all, the present invention is to produce a variety of building materials such as interior and exterior wall panels by making efficient mass production in the production of foamed ceramic panel 12, which is light and hard and gives great benefits to the human body, and at the same time can be supplied as land prices. To be used in various ways would be the effect of the present invention.

Hereinafter, the process from the first step to the sixth step will be described by way of example.

Example

Example 1 Process

14 kg of the base material (1) for red bricks used generally was prepared.

Example 2 Process

When the base was put into the refining machine 2 and discharged, a base plate 4 having a thickness of about 1 cm and a width of about 90 cm was continuously discharged, which was automatically cut to a length of 100 cm.

Example 3 Process

The plate 4 conveyed in the second process is placed on the upper surface of the lower mold 21 having 4 d side plates 21a, and the upper mold 22 is combined to form a horizontal 60 cm, a vertical 50 cm and a height. A 20 cm square box (8) was formed. (A base plate was molded with oil applied to the upper and lower mold outer surfaces.)

Example 4 Process

The blind box (8) was placed in a drying furnace (7) and dried for about 8 hours at a temperature of about 150 ° C-250 ° C.

Example 5 Process

Through the fourth process, the rectangular box 8 primarily dried was put back into another drying furnace 7 'and re-dried for about 5 hours within a temperature range of about 930 ° C to 1050 ° C.

Example 6 Process

In the middle of transferring the dried rectangular box (8) to the conveying conveyor (15 '), the foamable inorganic compound (10) was continuously introduced into the rectangular box (8) with an automatic feeding machine (9), and was evenly spread to a thickness of about 13.5 cm. .

Subsequently, when the fire fighting box (8) into which the expandable inorganic compound (10) was put was put into the firing furnace (11) and fired, the expandable inorganic compound (10) began to expand as it slowly swelled. ) And the foam are integrated into one foamed ceramic panel 12.

In addition, the upper surface of the foamed ceramic panel 12 was foamed with a slight uneven surface, while the remaining surface had a very smooth surface portion, and thus the foamed ceramic having a width of 60 cm, 50 cm, and 20 cm in height was completed. The panel will be immediately available for various building materials such as wallboard in the building.

The foamed ceramic panel 12 completed through several processes as described above was obtained, and by processing the panel 12 again, a superior product can be obtained. For example, by coating and glazing the outer surface of the panel, In order to improve visual beauty, and also to improve the health of the human body by applying fine particles (pigmentable) mixed with fluorite (18) and inorganic provider (19) on the outer surface of the panel (12) It can also be processed.

In addition, the finished product panel 12 may be decided whether or not to be reworked depending on the purpose of use, but whether or not a separate processing process is required, and thus, brick, tile, roofing material, exterior wall material, partition unit, inner wall material, wall plate, ceiling plate, It can be used in various applications such as hygroscopic plates, fireproof plates, blocks, slats, and non-combustible plates. Of course, once used as building materials, they can greatly contribute to the health of modern people.

In addition, the panel is foamed thick from the beginning and then cut several times in thin thickness to be used as various board materials such as nonflammable boards, and also processed and carved into stone shapes such as lions and tigers to be used as exterior wall materials or pillar decoration materials. Since most of the material is foamed, it is very easy to grind unlike stone such as granite, and after grinding, it can be applied to the outer surface by enamel glaze and fired again. Fine particles mixed with fluorite and inorganic binder It is also possible to apply (14) to beautifully treat the pores of the surface portion without a trace.

As described above, the present invention forms a foamed ceramic panel with a general base and an expandable inorganic compound, so that the weight is light and maintains the same strength as brick, so that it can be usefully used as various building materials. It is used to activate the biological rhythm by radiation energy such as far infrared rays emitted from foam ceramic panel, and to help the health of modern people in addition to the ripening, midnight and warming of various plants and animals. The method of manufacturing the panel itself can be automated in one line, so it can be said to be a useful invention in which various effects can be expected, such as mass production as well as low cost manufacturing.
