Apply to the glass surface with a thickness of 0.1-1mm, 70-90 Temperature was maintained dried, over an hour or more at a temperature of 800 ℃ relates to a process for the preparation of the glass characterized by a stand and adhered to glass and centripetal naengham granite layer.

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 also 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 glass in which effects such as protecting various substances and skin are expressed.

The present invention is described in more detail as follows.

Glass manufacturing method of 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 0.86 Deep granite composed of wt% and other trace components 1.11 wt% containing 0.5 to 2 ppm germanium, 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% Deep granite, consisting of 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, SiO ₂ 73.53 wt%, Al ₂ O ₃ 12.52 wt% , Fe ₂ O ₃ 4.76wt%, K ₂ O 3.78wt%, Na ₂ O 2.07wt%, CaO 1.56wt%, MgO 0.51wt% and other minor components containing 0.5 ~ 2ppm germanium heartiness After producing at least one of the granite granite in the granite as a powder having a particle size of 500 mesh or more, the specific gravity of 1.5 to 1.8 is selected and melted, at a thickness of 0.1 to 1mm on a known glass surface of at least one surface Apply and dry at the temperature of 70-90 ℃, then 800 ℃ or more It was maintained for 1 hour at a temperature characterized by the adhesive and the glass gradual cooling and centripetal granite layer.

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, each having a unique color, the color is a unique color formed by cooling the hot magma of 4000 ℃ or more and far-infrared emissivity is 0.90 or more.

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 10wt%.

The granite granules used in the present invention may be added in various particle sizes depending on the quality of the glass to be manufactured, but those having a particle size of 500 mesh or more in consideration of the surface smoothness of the glass, the transparency of the glass, and the required physical properties It is preferable.

The deep granite may be preheated, ground and powdered, or may be used as it is without heat treatment. 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 500 mesh (mesh) or more It is preferable to use it by grinding. If the particle size is less than 500 mesh, the melting is difficult and not economical, and there is a problem that the ease of manufacturing into glass is reduced and the transparency of the glass is lowered. The components are easily melted and the adhesion between the glass and the deep hardened rock layer is easy. There is a drawback to not doing it.

In the glass used in the present invention, any glass material commonly used in the technical field to which the present invention pertains may be used as the glass material. For example, quartz glass composed of 100% SiO ₂ , soda-silica (Na ₂ O.SiO ₂ ) glass and soda-silica glass in which soda ash is added as a modifying agent to the quartz glass. Soda-lime-silica (Na ₂ O.CaO.SiO ₂ ) glass to which CaO is added as a stabilizer to satisfy mechanical properties is commonly used in the technical field to which the present invention belongs. All glass materials to which the known additives used are added can be used.

In particular, silica, which is one of the main materials for glass making, should be colorless but usually contains slightly blackish particles, so it is preferable to remove blackish particles or other impurities by flotation, washing or magnetic beneficiation. If it is large, it is difficult to melt, and if it is small, a lot of air is generated and bubbles are generated in the glass. Therefore, it is effective to use a particle size of 0.1 to 0.5 mm, and as a regulator for melting quartz glass and facilitating work on glass products. Limestone, dolomite, soda ash, etc. can be added to inject CaO, and sodium nitrate, which is used to accelerate the melting process of the batch, is very good at homogenizing the glass at the temperature when most other raw materials have already decomposed. Useful forget-me-not, to make a brighter glass and oysters of glass Potassium carbonate to increase the yield, alumina to improve the workability of the glass, increase the mechanical and chemical resistance and reduce the crystallization tendency, B ₂ O ₃ , glass added to impart high thermal and chemical resistance and improve the glass melting PbO which gives a high refractive index and increases the density of the glass, a coloring agent for coloring the glass and the like can be added.

First, the mental granite is heated to 705 ° C. and maintained for 5 minutes, then maintained at 625 ° C. for 5 minutes, maintained at 580 ° C. for 30 minutes, and then heat-treated in a manner that is maintained at 705 ° C. for 10 minutes to a particle size of 500 mesh or more. What is not pulverized or heat-treated is pulverized as it is, powdered, and then selected and melted with a specific gravity of 1.5 to 1.8. After drying, the glass is maintained at a temperature of 800 ° C. or higher for at least 1 hour, and the glass and the deep granite layer are bonded to each other and slowly cooled to prepare the glass of the present invention.

When the specific gravity of the deep granite is less than 1.5, there is a disadvantage in that the thickness of the coating is reduced due to the low far-infrared emissivity, and the specific gravity exceeding 1.8 is difficult to obtain and it is not economical.

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. It is effective to melt by heating to 1050 degreeC or more, and to hold for 2 hours or more.

It is preferable to apply the deep granite melt to a thickness of 0.1 to 1 mm on at least one surface of a known glass surface. When the applied thickness is less than 0.1 mm, the degree of expression of various effects expressed by the deep granite is weak, and 1 mm is applied. If it exceeds, there is a disadvantage that the transparency of the glass is lowered or the adhesion of the deep granite is not easy. In addition, it can be easily inferred by those skilled in the art that the coating thickness can be changed depending on the use of the glass to be manufactured.

After the deepening granite is applied, it is dried at a temperature of 70 to 90 ° C. and solidified. If the drying temperature is less than 70 ℃, the energy consumption required for heating in the heat bonding process is increased again, it is not economical, and if it exceeds 90 ℃, the viscosity of the deep granite is less than the desired degree, the handling is not easy There is this.

After the drying process is maintained at a temperature of 800 ℃ or more for 1 hour or more so that the hearth hardened layer and the known glass is partially melt-bonded and slowly cooled to prepare a glass. In the case of melt bonding, the adhesive may be pressurized at a pressure of about 100 kg / cm ² .

In the glass of the present invention, far-infrared rays are radiated from the applied deep granite component, so that discoloration and the like can be prevented by disinfection and insecticidal effect, and the radiation energy of the atmosphere and the deep granite component coated on the glass and extremely small amount of remaining moisture The structure produces a mutual resonance effect to effectively absorb the heat source of the atmosphere, and reaches the maximum absorption of energy in the wavelength range of 4 to 25μ to obtain a cold protection effect. 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.
