Was added to pre-heat treatment of granite and glass composition characterized by the following, pressing, molding was also held for 4 hours then heated to melt 1050 ℃ and a method for producing a glass using the same.

In general, glass is manufactured using SiO ₂ as a main raw material, and is used for various uses such as window glass, plate glass, and bottle glass because of its transparency, excellent light transmittance, and low thermal conductivity. The structure of such glass is not as well known as most metals, it has a unique state, called the glass phase, and is defined as a 'melt product that is cooled to a hard state without crystallization'.

On the other hand, glass is generally manufactured through raw material preparation → weighing → batch mixing → molding → slow cooling → inspection and quality control → secondary process → inspection → packaging. Special processes may be added, such as strengthening, laminating, cladding, sand blasting, etching, metalling, and the like.

In addition, the glass can be made of glass of different colors by adding different colorants to the batch. For example, most metal oxides dissolve in glass to form colored transparent glass, and sulfur and selenium components appear colloidally in the glass, giving transparency to the glass, and opal glass gives fine fluorine to the glass. It is formed by having a crystalline content of the compound.

However, conventional glass is endowed with only glass intrinsic properties and effects, but no other beneficial properties. In particular, the radiant energy of the atmosphere, the deep granite component mixed with the glass, and the molecular structure of the extremely small amount of residual water have mutual resonance effects, effectively absorbing the heat source of the atmosphere and reaching the maximum absorption of energy in the wavelength range of 4-25μ. Not only can it obtain cold and warm effect, but the deep granite blocks the electromagnetic waves, expresses the functions of deodorization and deodorization, and the far-infrared rays emitted by the deep granite itself reflect the durable rays of paper harmful to the human body such as ultraviolet rays. There have been no studies and descriptions of various glass materials and colored glass expressing effects such as protecting the skin.

It is characterized by.

Further, the glass production process of the present invention, _{SiO 2 70 ~ 90wt%, Al} 2 O 3 2 ~ 10wt%, SiC 1 ~ 4wt%, ferrite (ferrite) 1 ~ 5wt% and _{SiO 2 79.76wt%, Al 2 O} 3 9.87 wt%, Fe ₂ O ₃ 0.21 wt%, K ₂ O 3.79 wt%, Na ₂ O 2.81 wt%, CaO 1.59 wt%, MgO 0.86 wt% and other trace components 1.11 wt% containing 0.5 to 2 ppm germanium Deep granite, SiO ₂ 73.41 wt%, Al ₂ O ₃ 14.56 wt%, Fe ₂ O ₃ 1.13 wt%, K ₂ O 4.13 wt%, Na ₂ O 2.48 wt%, CaO 2.28 wt%, MgO 0.72 wt% And deep granite composed of 1.29 wt% of other trace components containing 0.5 to 2 ppm of germanium, SiO ₂ 73.53 wt%, Al ₂ O ₃ 12.52 wt%, Fe ₂ O ₃ 4.76 wt%, K ₂ O 3.78 wt%, Na 2.07wt% O _2, CaO 1.56wt%, 0.51wt% MgO and a germanium-containing 2ppm 0.5 - other minor components of at least one of concentric granite consisting of 1.27wt% bell concentric granite powder 1 and glass compositions of a 3wt% to known To prepare a glass by adding to, but the heat treatment of the granite granite is added in advance and heated to 1050 ℃ to melt It was maintained for over four hours, and then characterized by, forming pressure.

The deep granite used in the present invention is SiO ₂ 79.76wt%, Al ₂ O ₃ 9.87wt%, Fe ₂ O ₃ 0.21wt%, K ₂ O 3.79wt%, Na ₂ O 2.81wt%, CaO 1.59wt%, MgO Deep granite (hereinafter referred to as "deep granite A") consisting of 0.86 wt% and 1.11 wt% of other trace components containing 0.5 to 2 ppm of germanium, SiO ₂ 73.41 wt%, Al ₂ O ₃ 14.56 wt%, Fe ₂ Deep granite consisting of 1.13 wt% O _3, 4.13 wt% K ₂ O 2.48 wt% Na ₂ O, 2.28 wt% CaO, 0.72 wt% MgO and 1.29 wt% of other trace components containing 0.5 to 2 ppm germanium Or "sintered granite B") or 73.53 wt% SiO _2, 12.52 wt% Al ₂ O _3, 4.76 wt% Fe ₂ O ₃ , K ₂ O 3.78 wt%, Na ₂ O 2.07 wt%, CaO 1.56 wt% , Which is composed of 0.51 wt% of MgO and 1.27 wt% of other trace components containing 0.5 to 2 ppm of germanium (hereinafter referred to as "deep granite C"), and at least one or more of the three types of granite It is preferable to select and use.

The deep granite used in the present invention is a pure magma in the crust is cooled in the reduced state and each has a unique color, the color is a unique color formed by cooling the high temperature magma of 4000 ℃ or more and known as far-infrared emissivity is 0.90 or more It is added in a ratio of 1 to 3wt% with respect to the weight of the glass composition, and when the addition rate of deep granite is less than 1% by weight, there is a disadvantage in that the desired effect is insufficient in the present invention. Not only is it not easy to manufacture, but the glass inherent properties are lowered and there is no economic effect because there is no synergistic effect of addition. Far-infrared emissivity changes according to the type of deep granite, the mixing method, and the mixing ratio used, so that glass of various characteristics and uses can be manufactured. That is, the deep granite A, the deep granite B, the deep granite C can be used independently, two or more kinds may be used in combination, and when used in combination, each of the deep granite is preferably used in more than 3wt%.

The granite granules used in the present invention may be added in various granularities depending on the quality of the glass to be manufactured, but it is preferable to use those having a particle size of 200 mesh or less in consideration of the surface smoothness of the glass and various required properties.

The carded granite is heat treated in advance, pulverized and powdered, and then added to a known glass composition. Heat treatment is carried out by heating to 705 ℃ for 5 minutes, then 5 minutes at 625 ℃, 30 minutes at 580 ℃, 10 minutes at 705 ℃, pulverizing is carried out by a particle size of 200 mesh (mesh) or more It is preferable to use it by grinding. If the particle size is less than 200 mesh, not only is it difficult to be economical due to melting is difficult, there is a problem that the ease of manufacturing work into glass is lowered, and it is sufficient that the components have a particle size that is easy to melt.

As the glass material, any glass material conventionally used in the technical field to which the present invention belongs can be used. For example, 70 to 90 wt% of SiO _{2 ,} 2 to 10 wt% _of Al ₂ O ₃ , 1 to 4 wt% of SiC, and 1 to 5 wt% of ferrite were used. Experimental results have been found to be preferred and it will be readily appreciated that known additives may be added to improve the use and product properties of the glass to be produced.

That is, silica sand (SiO ₂ ) is one of the main materials for glass manufacturing, and the silica sand particles should be colorless but usually contain some blackish particles, which removes blackish particles or other impurities by flotation, washing or magnetite mineralization. Preferably, the particle size should be about 0.1 ~ 0.5mm. If the silica particle size is large, it is difficult to melt, and if the particle size is smaller than 0.1 mm, a lot of air is injected to cause a lot of bubbles in the glass. The amount of silica sand is preferably 70 to 90wt%, and if the amount is less than 70wt%, the mechanical and chemical strength decreases and the thermal expansion rate increases, which weakens the thermal shock. If it exceeds 90wt%, it is difficult to melt and is a glass product. There is a problem that is difficult to work with.

In addition, Al ₂ O ₃ is added to improve the workability of the glass, increase the mechanical and chemical resistance, and reduce the crystallization tendency, and it is preferable to add 2 to 10 wt% in view of the above role, and SiC Is a stabilizer added to satisfy unsatisfactory chemical and mechanical properties, preferably 1 to 4 wt% is added. When the amount is less than 1 wt%, the addition effect is weak, and when it exceeds 4 wt%, the synergistic effect is added. There is no economic disadvantage.

Ferrite is added as a colorant component for producing colored glass, and it is preferable to use 1 to 5 wt%, and when used below 1 wt%, the coloring effect is insignificant, and when used in excess of 5 wt%, coloring is performed. Not only does not have a synergistic effect, there is a problem in reducing the chemical and mechanical stability of the glass. Instead of ferrite, a known colorant such as cobalt oxide, chromium oxide, iron oxide, manganese dioxide, nickel oxide, selenium, sulfur, uranium and the like can be added in an appropriate amount to obtain a colored glass of a desired color.

The above ingredients are powdered, put into a furnace and melted. When the powder is powdered, the particle size of the powder is preferably carried out at 200 mesh (mesh) or more, and when the particle size is less than 200 mesh, there is a problem in that melting is difficult and not economical, and the ease of manufacturing work into glass is reduced. It is sufficient that the components only have a particle size that is easy to melt. For melting, any melting apparatus conventionally used in the art to which the present invention pertains may be used, but it is effective to use a pot or a tank. Melting is effective by heating to 1300 degreeC or more at the temperature increase rate of 250-300 degreeC / hour, and holding it for 2 hours or more. If the temperature increase rate is out of the above range, the melting of the components may not be completed, so that the components may not be homogeneously mixed or the amount of fuel used for melting may be uneconomical. Maintain two hours at 1300 ° C. to ensure uniform mixing of each component.

The molten mixture is pressed and molded to a constant size using conventional methods and apparatus to produce the colored glass of the present invention.

In the glass of the present invention, the deep granulated granules contained in the glass are homogeneously mixed in the glass manufacturing, and far infrared rays are radiated from the mixed deep granulated steel to exhibit disinfection and insecticidal effects, thereby preventing discoloration and the like. The homogeneous mixed granite component of glass and the extremely low molecular structure of the remaining water cause mutual resonance effect, effectively absorbing the heat source of the air, and reaching the maximum energy absorption in the wavelength range of 4 ~ 25μ. Can be obtained. In addition, the deep granite blocks the electromagnetic waves, expresses the functions of deodorization and deodorization, and the far-infrared rays emitted by the deep granite components themselves are harmful to the human body such as ultraviolet rays and reflect the rays that cause the durability of the glass to deteriorate. And various effects such as protecting the skin.
