Description

Foamed ceramic material using silicon carbide

The present invention focuses on Si2 + 3C → SiC + 2CO based on ultrafine silicon carbide particles obtained through the reaction time of 1800 ℃ ~ 1900 ℃ and the reaction time of 10 ~ 30 hours, and it is clay, loess, feldspar, pottery stone, silica, lead stone, volcanic ash. After combining a certain ratio with the fine particles, such as zeolite and bentonite, and then firing within a temperature range of about 1050 ℃ to 1250 ℃ to prepare a foamable ceramic material.

As is well known, when firing complex inorganic compounds such as clay, loess, feldspar, etc., which are not mixed with silicon carbide, firstly, it is difficult to foam a certain size (pore formation) and secondly, the size of the pores is very irregular. Third, the voids may be formed only on one side of the molding, and the fourth: one side of the molding may have a large void, and the other side may have small voids. There are some problems that can be said, such as a big change and a bumpy effect, but there may be problems such as mixing problems and temperature deviations in the kiln, but the main cause is expansion by heat when leading to a cooling line at the melting point where foaming is completed. The main problem occurs in the shrinkage of the fired material itself during the cooling process, which is converted to low temperature. Crushed or distorted phenomena occur a lot).

On the other hand, modern buildings are becoming increasingly higher on a limited land area, and thus, the weight reduction of building materials is more urgently required, but it is not an exaggeration to date, but it is still lighter and cheaper than cement materials. Development has not been achieved, and therefore, the construction and transportation of construction materials due to prolonged periods of construction and excessive weight had to be a big challenge. Since the end was followed, in recent years, the transition to steel frame and steel structure has spurred the assembling of buildings, and therefore, it is urgent to develop lighter construction materials.

Therefore, the present invention has a primary purpose of providing a very lightweight foamable ceramic material which is much lighter than the building materials made of general cement and is very beneficial in relation to the human body, but more importantly, the use of silicon carbide is highly effective for foaming properties. It is to provide a ceramic material.

In other words, there have been some cases in which conventional silicon materials are partially included in the manufacture of general ceramic materials, but these are only secondary parts rather than used in consideration of the importance of silicon carbide. Silicon carbide according to the present invention can be said to have been developed in consideration of the correlation with the composite inorganic compound which will play a pivotal role and function in the present invention, and at the same time, which will be described in more detail with respect to the manufacture of traditional ceramic materials The explanation is as follows. In other words, the difference between the manufacture of ceramic material and the foam ceramic material, which has been traditionally followed, first of all, in the former case, the hot-fired materials are contracted in addition to the maintenance of the vacuum state, whereas the foam ceramic material expands and expands so that the opposite phenomenon occurs. However, both the former and the latter are equally required for the absolute stability of the substance after high temperature and firing. In addition, the former has been developed for the stabilization of raw materials and substances for thousands of years. Not only are there many examples, but among these raw materials, there are a lot of expandable raw materials and the main factor for using the expandable raw materials is to lower the firing temperature and to shorten the firing time due to the expansion of the material, but sometimes a part of the fired material due to incorrect composition Doors that cause a fire While there are some problems (such as air holes in the interior and surface areas of the traditional ceramic materials, they are treated as defective products), the inorganic raw materials of the foamed ceramic materials are the most smooth among the many expandable raw materials. At the same time, only the raw materials are selected and the raw materials are formulated according to the combination ratio, and the mixed composition is calcined again at high temperature to produce the foamed ceramic material. The foamed ceramic material thus prepared has different specificity according to the combined composition. According to the use can be divided into various ways.

However, as mentioned above, when high temperature firing is performed in which a mixed inorganic compound (composition) such as clay or silicon carbide, which is not mixed with silicon carbide and mixed at an appropriate ratio, (i) foaming of a certain size (pore formation) It is difficult to cause a large amount of problems such as (ii) the voids are foamed in a very irregular state, and (iii) the voids are formed only on one of the moldings.

Therefore, in order to solve these problems, various inorganic materials such as clays are formed according to the combination ratio, and the ratio of silicon carbide (SIC) is added or mixed at the same or different ratio according to the properties or characteristics of each composition so that high temperature and When firing, it is possible to completely eliminate the above-mentioned problems such as difficult formation of a certain size of pores or foaming with very irregular sizes of pores, thereby making construction materials such as various interior and exterior materials, which are beneficial to the human body, most economical. There is another big purpose in that it can be provided.

In addition, the use of silicon carbide according to the present invention can produce high quality products at the lowest cost, and at the same time, the formation of even pores has various effects such as light weight of the product and the vacuum of the pores, resulting in sound insulation, sound absorption, and heat storage. This is also another object that the present invention aims at.

As described above, the technical problem to be achieved by the present invention will be described in more detail as follows.

The fine particles of clay, loess, feldspar, pottery stone, quartzite, feldspar, volcanic ash, zeolite, bentonite, etc. are mixed with silicon carbide under a combination (so-called combination inorganic particles such as clay or loess). This is first molded into plate, block, aggregate (artificial gravel), artificial sand, etc., and then dried to less than 10% of moisture, and then calcined at 1050 ℃ ~ 1250 ℃, while maintaining a certain time at the melting point to give a part of porous particles When dissolved, the fine particles dissolve and act as nuclei during sublimation, resulting in foaming. In addition, some components in the volcanic ash, zeolite, and bentonite are dissolved in the raw material of the composite inorganic compound, and dissolved into alkali to decompose the silicon carbide, and the silicon carbide is decomposed (pore). It gives a strong feeling of expansion to the inside and accordingly the cooling curve of the cooling stage (from the melting point of about 1200 ℃ to about 300 ℃ from the melting point to about 300 ℃ slowly slow down while cooling, the cooling graph at this time is not curved It is possible to produce a lightweight foamed ceramic material having a foaming (pore) size required by controlling the amount of silicon carbide and the amount of particulate matter formed without changing the foamed material in the straight form). There is a purpose.

The present invention is very beneficial to the human body while being able to realize a light weight, first look at the preparation process before entering the manufacturing, the primary grinding the ore ore in the specialized processing company such as hammer mill or roller crusher or jao crusher Subsequently, after having 60 or more meshes finely pulverized with a Raymond mill, a vibrating mill or a wet ball mill, the combined composition is pulverized again to about 200 mesh or more according to the mixing ratio, and then mixed. After mixing and kneading 1000 micron or more silicon carbide ultrafine particles, which are the main materials, and molding them into a large pottery machine or a large press (when the mixed fine particles are dry, they make a box with a shelf and apply kaolin, etc. A method of firing and foaming the box containing two-thirds of the fine particles mixed therein is adopted. After yojeok to that to be produced by sintering and a firing ceramic material is light weight foamed at 1050 ℃ ~ 1250 ℃, it will now be described below for each method step follows.

However, as mentioned above, what is most emphasized and pointed out in the present invention is the combination ratio between the raw materials of the composite inorganic compound and silicon carbide described below, especially the input ratio of silicon carbide and the composite inorganic compound. It is the function and role of silicon carbide in the environment.

1st process: raw material preparation process

Clay and loess have more than about 60 mesh crushed, feldspar, pottery stone, quartzite, feldspar, dolomite, calcite, waste glaze, aggregate quarry sludge, volcanic ash, zeolite, bentonite, etc. Silicon carbide is provided with 1000 mesh or more.

In addition, the composite inorganic compound used in the present invention refers to particulate matter that is suitably mixed in accordance with the combination ratio of the third process described later in the state of granulating each raw material such as clay and feldspar. Among the raw materials mentioned, volcanic ash, waste glazing, aggregate quarries sludge, etc., are actually exaggerated to be over 200 mesh at the time of raw material input (because these raw materials are finely pulverized so that they can no longer be used). In the present invention, it is a very good raw material because it is easier to foam as it becomes finer in the present invention.

2nd process: simple test process

It refers to the process of analyzing and testing the properties of each inorganic material such as melting point, plasticity, water content, and viscous force. The principle is to go through such simple test process whenever each raw material is received.

Third Process: Combination Composition Process

Based on the simple test, the raw materials are formulated to have a trouble-free combination ratio in the foamed phase. Here again, this combination process is the core and most important process in the present invention.

In other words, the processes for preparing and inspecting the foamed ceramics after the first raw material preparation process are completely introduced by the applicant's prior application patents. The combination ratio between the compounds and silicon carbide is the result obtained after numerous studies and repeated experiments for the formation of a certain size of foam and the like. It is not an exaggeration to say that the development of general ceramics and foamed ceramics is not only a series of processes, but also the selection of raw materials and the composition of the composition ratio. Greater weight To be sure a timely manner.

And in addition to the combination process according to the present invention is a fact that there are a number of combination ratios, but it is hardly economical. In other words, the present applicant is also inexpensive and easy to find a method that can be manufactured by combining as described below can be produced at a low price high-quality foam ceramic material.

※ Table 1: Combination Ratio Relationship between Complex Inorganic Compounds and Silicon Carbide

※ For example, the reason why limestone can be used instead of Park Unseok is because the characteristics and characteristics of each other are generally the same.

Fourth Process: Grinding Process

Of each raw material created by combination ratio of the third process

1) In the case of fine grinding using dry method (raw material grinding), ocher and clay are finely ground with palm mill to be 100 mesh or more, and feldspar, silica, pottery stone, dolomite, dolomite, calcite, waste oil. Weak ground, aggregate quarry sludge, volcanic ash, zeolite and bentonite are ground in a vibrating mill for 2 to 12 hours so that the average is 200 mesh or more, and the specific gravity is calculated as the specific gravity of 1.1 to 1.4.

2) In the case of pulverizing by using the wet method (the method of pulverizing with the addition of moisture to the raw materials), grind it with a ball mill for 10 to 24 hours, but add 45% to 65% of water so that the average is over 200 mesh. At this time, the specific gravity is 1.1-1.4, and the fineness is pulverized so that the residue amount is 0.4g ~ 5g or less.

3) Of the raw materials mentioned above, the finer particles than 200 mesh from the time of receipt do not need to go through the fine grinding process of the fourth process.

5th process: stirring process

[Section 1) of the fourth process does not require the fifth process]

The pulverized composite inorganic compound is placed in a slip tank, stirred to prevent the formation of precipitates, and 2.4 / 1000 calcium chloride is used to prevent precipitation.

6th process: Filter Pressing process (cake making process)

[Section 1) of the fourth process does not require the sixth process]

In the fifth step, the finely ground pulverized product is removed by moisture with a filterta press and then caked. At this time, the dihydrate content is 20% to 25% and possessed.

※ Separate process [another method of the sixth process]

When the finely ground product is required to be dry or pressed after the fine grinding of the composition of the fourth step 2) with a ball mill, the wheeltapressing step of the sixth step is carried out after the stirring air in the fifth step. The drying step of the eighth step, which will be switched to the following, will be omitted.

7th process: molding process

1) The cake cake in the sixth process can be molded with a large scale grinder (this means molding the dough into a variety of building materials such as interior and exterior materials while being slightly rusted and flour-like.

2) As shown in the separate process shown in the bottom of the 6th process, as shown in the separate process of the table, the material dried by the spray dryer machine can be molded by pressing with a press machine or squared without the upper surface formed by baking board. It is also possible to shape the dried body in the box.

③ Paragraph 2 of the 7th process is to dry the material to some extent such as the state of the dough dough and then to shape it into the desired manufacturing form with a press or to put the material into a rectangular box having a certain mold (molding) to fire and foam.

3) And as previously described in 1) of the fourth process, by filling a predetermined amount of finely ground dry powder into a predetermined rectangular box containing no upper surface, the finely ground pulverized powder in the dry state is formed of a baking board. Finish the molding work.

(Moulding in this tree means filling two-thirds of the finely ground dry powder in a rectangular box with a constant mold)

8th process: drying process

In the case of paragraph 1) of the seventh co-operation, the molded product after the molding process is dried in a drying chamber at 150 ° C. to 300 ° C. for about 10 hours or more until the water content is 10% or less.

In the case of 2) and 3) of 7th process, the drying process which is 8th process is unnecessary.

9th process: loading process

The dried molded product is to be loaded on a trolley which is one of the conveying means.

10th process: firing process

The firing temperature varies slightly depending on the combination ratio of the third process, but the melting time should be appropriately given from the melting point. In the subsequent cooling after the melting, the cooling temperature is slowly cooled while allowing the falling temperature to be linear rather than curved.

In addition, the loading of the trolley described in the ninth process is a method used when the trolley is put into a tunnel kiln or a shackle kiln and fired. This method is used when the finely ground dry powder is pushed into the firing state as it is, but the firing process is the same for both firing furnaces, and the firing curve and melting point are different in some of them. The melting time and the atmosphere in the kiln where the cooling temperature in the cooling process should be cooled slowly in a straight line form are all the same.

(See Chart II below)

Table Ⅱ: Firing Process Chart

And the temperature rising to the molding from the firing process of the curved form to the melting point is usually 1050 ℃ ~ 1250 ℃, there is no problem according to the temperature rise time, but the melting time for each composition combined, that is, the melting point at which the composition began to melt (foam) The continuous melting time starting from, and will usually need to last about 25-30 minutes.

On the other hand, when looking at the operation and role of silicon carbide, which is the most important matter and the core of the present invention, in terms of the firing process, firstly, when the plastic melting point is reached, the foaming properties such as zeolite and bentonite are mixed among inorganic materials mixed with feldspar and silica. Strong materials act as foaming cores to form voids and stimulate the foaming of other materials around them, followed by melting alkails generated during melting to break down silicon carbide. by disassembling and allowing the expanded pores to expand further as the silicon carbide decomposes, thus making the silicon carbide lighter.

In addition, it should be noted in the present invention that the foam having the pores further expanded by silicon carbide is gradually lowered the cooling temperature such that there is no shrinkage or distortion of the foamed pores generated during the cooling process in the kiln, It is necessary to cool slowly in a straight state, and one very important fact is the proper input of silicon carbide. In other words, only a small amount of silicon carbide should be added and mixed to the inorganic raw materials mixed at a certain ratio, so that the foaming stability can be achieved without any side effects or adverse effects.

Hereinafter, the present invention will be described with reference to Examples. (Only Examples according to a dry process will be described.)

4th process: fine grinding process (dry process only)

The expanded composite inorganic compound prepared at the combination ratio of the third step was put into a vibration mill and pulverized for 4 hours, and then pulverized into fine particles of about 220 mesh, and the specific gravity was 1.3.

5th process: forming process

A box-shaped box-shaped box without a lid is made of a shelf for baking, and then kaolin powder is applied therein, and therein, the particulate powder of the expandable composite inorganic compound prepared in the fourth step is put thereinto form a molded article. In order to achieve or to put the dried material in a spray dryer in the rectangular box to form a molded body to be formed.

6th process: loading process

By the fifth process, moldings deposited on the baking shelf were loaded on a trolley one after another.

7th step: firing process

As mentioned above, the firing environment of the kilns such as tunnel kilns and lorskin kilns is slightly different, but the firing furnaces have to be cooled slowly and slowly with the main firing curve, the melting time at the melting point, and the cooling temperature at the cooling zone in a straight state. The atmosphere inside was the same, and the temperature rising to the molding from the firing curve to the melting point was mainly 1050 ° C to 1250 ° C. The problem of the temperature rise time was not restricted (although time is not critical), but the combined composition Melting time (melting time) at each melting point was important to achieve the completeness of the foam, so it had to be observed.

The results obtained in the test firing will be described below, and the cooling temperature graph should be very slow cooling as a straight line, so the cooling zone in the kiln was extended to be slow cooling.

Firing example

Example In the inorganic raw material combination example of a 3rd process,

In the case of 1), it melted for about 25 minutes at 1100 ° C, which is a melting point temperature, and cooled slowly.

In the case of 2) and 3), the melting point was set at 1170 ℃ and then cooled for 30 minutes.

After the plastic was sufficiently cooled, the rectangular box was dismantled to remove the plastic, and then the screening was checked to see if the foaming was correct, whether the void phenomenon was not oriented too much, and the pore size was uniform.

As mentioned above, foamed ceramics (floating ceramics) can be obtained through various processes.The finished foamed ceramic materials may be reworked depending on the purpose of use, but depending on the processing, bricks, tiles, roofing materials, ceiling materials, interior and exterior materials, etc. Not only can be used in various ways, but as described in the previous molding process, if it is completed through the whole process in the state of being formed with gravel or sand, etc., it can be used immediately regardless of processing.
