Abstract

PROBLEM TO BE SOLVED: To enable the reuse of glass obtained from waist glass, etc., the baking at wide temperature zone, the reduction of the discharge of carbonic acid gas at a low temperature range and the use of glass as constructional material for building by baking a molded body produced using a specific molding raw material. SOLUTION: Glass granules generated in a glass manufacturing process, etc., and glass granules obtained by crushing waste glass, having an average particle diameter of 2-5mm, are used as raw materials. These granules with the upper limit of weight ratio of 80wt.% are kneaded with ceramic clay such as potter's clay, kibushi-clay or bentonite while adjusting water content to obtain a raw material for molding. A molded body produced from the obtained raw material for molding by wet extrusion molding or dry press molding is baked at a temperature in a wide temperature zone such as 700-1300 deg.C, and this process enables the control of baking by combining perfect sintering and partial sintering. That is, low temperature baking such as at about 700 deg.C gives lower strength than high temperature baking, but it reinforces the strength by the melt of glass and gives a sintered compact having a specific decorative effect.

However, the melting point of glass is considerably lower than that of baked goods, and from the viewpoint of strength, it is much lower than that of a fired body obtained by firing a clay material. The viscosity of the glass is 600
About 10 ° C, about 10 times higher than normal temperature, 700 ° C
In this case, partial sintering occurs by about 10 8 times.
That is, when the temperature reaches about 700 ° C., atoms or molecules move on the surface of the glass particles, and are bonded to other firing materials, thereby forming a partially sintered fired body. However, a method of realizing a fired body by partial sintering at an extremely low temperature of 700 ° C. is not practical and has hardly been performed conventionally.

In addition, when waste glass or the like is effectively used as a raw material, there is a problem that crushing to a small particle size requires a processing cost.

When the materials to be sintered are in contact with each other at the time of sintering, constituent atoms are first evaporated on the surface, and the atoms are aggregated at the contact portion to form a sintered contact portion.
This is the evaporation-condensation process. In the low-temperature sintering, surface diffusion of atoms occurs thereafter, and in the high-temperature sintering, volume diffusion occurs. In the present invention, a large glass particle having a particle diameter of 2 to 5 mm is used as a raw material and fired in a wide temperature range of 700 to 1300 ° C. This is controlled by a combination of complete sintering and partial sintering. It is because of that.

When firing at a low temperature such as 700 ° C. using glass particles having a particle size of 2 to 5 mm as a raw material, heat conduction is difficult due to the large glass particle size, and volume diffusion occurs only in a part of the material. The body is partially sintered. However, when glass particles having a large particle size are used even when obtained by firing at such a low temperature, the physical properties and colors of the fired body greatly change, and the unevenness of color and the interestingness of the fired product appear, and the decorativeness is increased. There is a characteristic that an effect can be obtained. In the case of ceramic clay, complete sintering at 1000 ° C or higher,
As the temperature further increases, volume shrinkage occurs. In the case of low-temperature firing at about 700 ° C., the clay is partially sintered to form a coarse fired body, but a suitable fired body cannot be obtained unless the clay content is reduced to some extent. If the glass content exceeds 60% by weight, the properties of the glass become stronger.

[0011] In the case of low-temperature firing, the strength of the fired body is lower than in the case of high-temperature firing. It has the advantage of gaining body. In the case of such low-temperature firing, although the strength is slightly lowered, a characteristic feature is that a fired body having a specific decorative effect can be obtained by using the glass particles as described above.

On the other hand, in the case of high temperature firing, the particle size is 2 to 5 m.
Even if glass particles such as m are used, sufficient heat conduction is performed, so that volume diffusion is likely to occur, and at the same time, glass is easily melted, glass is easily diffused, and the glass is uniformly mixed. A completely sintered body is obtained. The characteristic of the fired body by high temperature firing is that the degree of shrinkage by firing is large,
Therefore, the dimensional accuracy is reduced, but the strength of the fired body is improved, and a dense fired body having a low water absorption is obtained.

As described above, the method for producing a sintered fired body according to the method of the present invention is characterized in that a fired body is produced using glass particles having a large particle size of 2 to 5 mm as a raw material. By controlling the partial sintering and the complete sintering by widely combining the particle size and the sintering temperature, 700 to 13
It enables firing in a wide temperature range of 00 ° C. Normally, firing in a wide temperature range of 700 to 1300 ° C. requires changing the composition and type of the material to be sintered, but in the present invention, the particle size of the glass particles and the mixing ratio of the glass are changed without changing the composition. It is possible by changing.

Although the larger the ratio of the glass particles in the raw material for molding, the more efficient the glass waste material and the like is, the more efficient it is, it is necessary to obtain a dense and high-quality fired body. The weight ratio is preferably up to about 80% of the raw material for molding by weight. The raw material for molding prepared from the glass granules and the clay for ceramics is adjusted in moisture, molded into a predetermined shape such as a tile, and fired. As a molding method, any of a wet extrusion molding method and a dry press molding method can be used. The firing conditions can be either oxidation firing or reduction firing. The complete melting temperature of a simple glass is 1350 to 1500 ° C. However, when firing is performed using a molding raw material in which glass granules and ceramic clay are mixed as in the present invention, complete sintering by a simple glass is performed. It can be fired at much lower temperatures.

Further, since sintering can be performed in an extremely wide temperature range of 700 to 1300 ° C., firing in a low temperature range reduces carbon dioxide gas discharged during firing by 30% or more. It is possible to provide a sintered fired body having a high utility value that can be produced with consideration for the environment. In addition, since large glass particles such as 2 to 5 mm are used, particularly, glass particles obtained from waste glass can be processed at a lower cost as the particle size is larger, easier to handle, and easily used as a raw material for a fired body. It becomes possible. In addition, when used as a raw material for a fired body, it can be expected to consume a large amount in terms of quantity, making it possible to effectively use glass waste materials and to effectively reuse resources, and also to protect the environment. There are effects such as helping.

According to the method for producing a sintered body in a wide temperature range using glass particles as a raw material according to the present invention, it is possible to perform firing in a wide temperature range as a sintered body using glass particles as a raw material. It can be used as an architectural structural material having excellent properties in terms of physical properties such as strength, and can be used for various applications. In addition, by setting the particle size of the glass particles to be used as extremely large as 2 to 5 mm, which is not conventionally used, the effect of performing partial sintering due to incomplete melting of glass can be effectively used. Further, since the particle size is large, the cost for crushing the waste glass can be reduced, the economic efficiency can be increased, and the resources can be effectively reused. In addition, the sintering and firing in a low temperature range can reduce the amount of carbon dioxide gas emitted during firing, thereby providing significant effects such as effective contribution to environmental conservation.
