Description

Technical Field

[0001] The present invention relates to the technical field of glass manufacturing, and more particularly to a near-zero self-explosion video photoelectric glass and a preparation method thereof. Background Art

[0002] Currently, the price of LED video glass on the market ranges from 3,000 to 28,500 yuan per square meter, depending primarily on the model and specifications. Key factors influencing cost include resolution, pixel count, brightness, and maintenance costs during the warranty period. Maintenance costs are a significant constraint on the widespread adoption and use of LED video glass, particularly the common and challenging issue of patch replacement caused by tempered glass spontaneously exploding over long periods of use. Currently, the tempered glass used on the market is mostly standard clear white glass, ultra-clear glass, or colored glass, with spontaneous exploding rates of approximately 3‰, 1‰, and 0.5‰, respectively. Even with high-quality glass, the risk of spontaneous exploding cannot be completely eliminated. The primary cause of tempered glass spontaneous exploding is nickel sulfide (NiS) impurities within the glass. During use, the glass undergoes a crystal transformation and volume expansion, causing it to suddenly shatter without external force. This spontaneous exploding cannot be detected visually and has no fixed time of occurrence; it can occur anywhere from days to years after leaving the factory, leading to frequent maintenance requirements for LED video glass during project operation.

[0003] During the warranty period, replacement of patches for LED video glass typically falls into three categories: replacement due to tempered glass spontaneous explosion; replacement due to LED lamp failure resulting in display loss; and replacement due to other causes such as damage to the wiring, integrated circuit board, or human impact. Tempered glass spontaneous explosion is a physical phenomenon that cannot be completely controlled and is a major factor contributing to the high repair rate. The spontaneous explosion rate of ordinary tempered glass typically ranges from 1‰ to 3‰, and can even reach as high as 3% for some manufacturers due to process variations. Even with the use of ultra-clear glass or controlled impurity content, it is difficult to fundamentally avoid the risk of hidden damage caused by nickel sulfide phase transitions. This uncertainty seriously hinders the application of LED video glass in high-end architecture, outdoor advertising, and other applications requiring high safety and stability. Consequently, existing technologies commonly suffer from the following issues: a high tempered glass spontaneous explosion rate, unpredictable glass explosion timing, and high subsequent maintenance costs. In particular, the need for module replacement due to spontaneous explosion has become a core bottleneck limiting the reliability and application value of LED video glass. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a near-zero self-explosion video photoelectric glass and a preparation method thereof, comprising a tempered glass layer made of ice crystal blue glass raw material and subjected to heat-dip homogenization treatment, wherein the glass layer is sandwiched with LED lamp beads, a controller and an integrated power board, and double-layer glass is encapsulated on the outside. The nickel sulfide phase change is promoted by high-purity low-sulfur raw material and heat treatment, and the self-explosion rate is dually controlled from the source and the process link, thereby solving the problem of patch replacement caused by frequent self-explosion of tempered glass in existing LED video glass, and realizing the effective unity of structural safety and display stability.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a near-zero self-explosion video photoelectric glass, the photoelectric glass comprising an ice crystal blue tempered glass layer and an LED display layer, the ice crystal blue tempered glass layer being made of an ice crystal blue glass original sheet, the LED display layer being arranged on the ice crystal blue tempered glass layer, the ice crystal blue tempered glass layer being subjected to a heat-dip homogenization treatment, the heat-dip homogenization treatment comprising heating the tempered glass to 260°C±10°C and keeping it warm to accelerate the phase change of nickel sulfide and reduce the self-explosion rate.

[0006] As a further solution of the present invention, the self-explosion rate of the ice crystal blue glass original piece is one in one hundred thousand (10 ppm).

[0007] As a further solution of the present invention, the self-explosion rate of the ice crystal blue tempered glass after the heat-dip homogenization treatment is reduced to below one part per million (1ppm). Hot-dip homogenization treatment is an industry-recognized effective method to reduce the self-explosion rate of tempered glass. Its effect is verified by EU standards and a large amount of experimental data. The specific reduction varies depending on the process level and the quality of the original glass, but the self-explosion rate can generally be reduced from 0.3% to 0.8% to below 0.1%, or even close to 0.01%. According to EU standard EN14179-1, the self-explosion rate of homogenized tempered glass that has been heat-dip treated needs to be reduced to less than 1 case per 400 tons of glass, which is equivalent to a self-explosion rate of about 0.0025% or less in actual application scenarios. The present invention combines the low self-explosion characteristics of the ice crystal blue glass original sheet to further reduce the self-explosion rate to below 1ppm.

[0008] As a further embodiment of the present invention, the ice blue glass raw sheet is produced by a sodium sulfate clarification process. The sodium sulfate clarification process includes decomposing sodium sulfate in a reducing atmosphere to reduce the residual sulfur content. The sodium sulfate (Na2SO4) undergoes the following reaction during the glass melting process. In the first stage, in a reducing atmosphere, the sodium sulfate begins to decompose at 400°C and reacts violently at 500°C to generate Na2S and sulfide. The specific chemical equation is:

[0009] Na2SO4+2C→Na2S+2CO2↑;

[0010] Na2S+Na2SO4+2SiO2→2Na2SiO3+SO2↑+S↑(865℃);

[0011] In the second stage, at high temperature (1200℃~1300℃), the saltpeter decomposes into SO2 and O2, achieving clarification of the glass liquid. The chemical equation is:

[0012] 2Na2SO4→2Na2O+2SO2↑+O2↑;

[0013] 2Na2SO4+2SiO2+C→2Na2SiO3+CO2↑+2SO2↑(720℃~1000℃);

[0014] In the third stage, SO2 reacts with O2 to form SO3 in an oxidizing atmosphere, further improving the clarification quality. The chemical equation is:

[0015]

[0016] O 2- +SO3=SO4 2- ;

[0017] By controlling the melting furnace atmosphere (weakly reducing atmosphere near the hot spot and weakly oxidizing atmosphere behind the hot spot), the ice blue glass raw material maintains a low residual sulfur state during the production process, significantly reducing the generation of nickel sulfide impurities.

[0018] As a further solution of the present invention, the LED display layer includes LED lamp beads and a driving circuit, and the LED lamp beads are evenly distributed on the ice blue tempered glass layer. The present invention aims to solve the problem of patch replacement of LED video glass caused by self-explosion of tempered glass. By reducing the self-explosion rate, the damage to the LED display layer caused by self-explosion and the replacement cost are significantly reduced.

[0019] As a further scheme of the present invention, the present invention also provides a research and development method for manufacturing near-zero self-explosion video photoelectric glass, the method comprising the following steps: providing an ice crystal blue glass original sheet, the self-explosion rate of the ice crystal blue glass original sheet being one hundred thousandth (10ppm), tempering the ice crystal blue glass original sheet to make ice crystal blue tempered glass, and performing a heat-dip homogenization treatment on the ice crystal blue tempered glass, the heat-dip homogenization treatment comprising heating the tempered glass to 260°C±10°C and keeping it warm to accelerate the phase change of nickel sulfide, and arranging an LED display layer on the ice crystal blue tempered glass that has been subjected to the heat-dip homogenization treatment to make near-zero self-explosion video photoelectric glass.

[0020] As a further solution of the present invention, the time of the hot-dip homogenization treatment is determined according to the glass thickness and the nickel sulfide content to ensure that the nickel sulfide undergoes sufficient phase transformation. During the tempering process, the α-phase nickel sulfide at high temperature does not have time to transform into the low-temperature stable β-phase due to rapid cooling. During use, the metastable α-phase at room temperature slowly transforms into the stable β-phase, accompanied by about 4% volume expansion, which will cause the tempered glass to self-explode. The hot-dip homogenization treatment promotes the rapid completion of the crystal phase transformation of the nickel sulfide in the tempered glass by heating to 260°C±10°C and keeping it warm, so that the glass that may self-explode is broken in advance in the hot-dip furnace of the factory.

[0021] As a further solution of the present invention, the preparation of the ice blue glass raw sheet includes controlling the atmosphere in the melting furnace so that the atmosphere near the hot spot is a weak reducing atmosphere and the atmosphere behind the hot spot is a weak oxidizing atmosphere to reduce the solubility of sulfur. In order to reduce the solubility of sulfur near the hot spot, the flame near the hot spot must be kept in a weak reducing atmosphere and the flame behind the hot spot must be kept in a weak oxidizing atmosphere so that the reaction equilibrium proceeds in the direction of SO3, thereby optimizing the clarification effect of the glass liquid and reducing the residual sulfur content.

[0022] As a further solution of the present invention, the setting of the LED display layer includes fixing the LED lamp beads on the ice crystal blue tempered glass through an adhesive and connecting the drive circuit. The present invention uses ice crystal blue glass raw sheets with a self-explosion rate of one in one hundred thousand. After producing tempered glass, the ice crystal blue tempered glass is again subjected to hot dip homogenization treatment to ensure that the self-explosion rate is reduced to below 1 ppm, achieving a near-zero self-explosion effect.

[0023] Compared with the prior art, the near-zero self-explosion video photoelectric glass and its preparation method of the present invention have the following beneficial effects:

[0024] This invention uses ice crystal blue glass sheets, which have a self-explosion rate of only 1 in 100,000, as its base material. After tempering, the glass is further subjected to a high-temperature aging process using a hot-dip homogenization process. This allows any nickel sulfide impurities in the glass to undergo a phase transition before shipment, thus preemptively eliminating glass sheets with a risk of self-explosion. This technological approach simultaneously addresses both raw material purity control and post-processing, significantly reducing the self-explosion rate of the final product. The self-explosion rate of tempered glass treated with this method can be further reduced from 1 in 100,000 in the raw sheet stage to 1 in a million. In comparison, conventional clear white glass has a self-explosion rate of approximately 3‰, ultra-clear glass has a self-explosion rate of approximately 1‰, and colored glass, such as green glass, has a self-explosion rate of approximately 0.5‰. Even high-quality glass carries the risk of unpredictable cracking. Through these innovative processes, this invention effectively avoids the problem of sudden breakage of tempered glass during use, significantly reducing the frequency of LED video glass patch replacements due to self-explosion, lowering maintenance costs, and improving product stability, safety, and commercial value.

[0030] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] A method for preparing near-zero self-explosion video photoelectric glass, the specific implementation steps are as follows:

[0032] First, we selected ice blue glass sheets as the substrate, which has a self-explosion rate of 1 in 100,000 (10ppm). Ice blue glass sheets are produced through a Glauber's salt clarification process to reduce the residual sulfur content in the glass, thereby reducing the formation of nickel sulfide (NiS) impurities. The reaction of Glauber's salt (Na2SO4) during the glass melting process is divided into three stages: In the first stage, in a reducing atmosphere, Glauber's salt begins to decompose at 400°C, and the reaction is intense at 500°C, generating Na2S and sulfides. The specific chemical equation is:

[0033] Na2SO4+2C→Na2S+2CO2↑;

[0034] Na2S+Na2SO4+2SiO2→2Na2SiO3+SO2↑+S↑(865℃);

[0035] In the second stage, at high temperature (1200℃~1300℃), the saltpeter decomposes into SO2 and O2, achieving clarification of the glass liquid. The chemical equation is:

[0036] 2Na2SO4→2Na2O+2SO2↑+O2↑;

[0037] 2Na2SO4 + 2SiO2 + C → 2Na2SiO3 + CO2↑ + 2SO2↑ (720℃ - 1000℃);

[0038] In the third stage, under an oxidizing atmosphere, SO2 reacts with O2 to form SO3, further improving the clarification quality. The chemical equation is:

[0039]

[0040] O 2- + SO3 = SO4 2- .

[0041] To optimize the clarification effect, the atmosphere in the melting furnace is controlled so that the area near the hot spot is in a weakly reducing atmosphere and the area behind the hot spot is in a weakly oxidizing atmosphere to reduce the sulfur solubility. As Figure 3 shown in the relationship curve of sulfur solubility and glass redox potential, where the horizontal axis is Fe 2+ / Fe (%), and the vertical axis is the sulfur content (calculated as SO3, %). The empirical redox curve shows that the sulfur content in the glass melt of typical ordinary soda-lime glass calculated as SO3 reaches a minimum value in the reducing state where Fe 2+ / Fe is about 75%. In this embodiment, by controlling the batch and flame redox, keeping the glass melt at the hot spot with a low SO3 solubility is one of the conditions for producing high-quality glass products.

[0042] Subsequently, the original ice crystal blue glass sheet is tempered to make ice crystal blue tempered glass. During the tempering process, the glass is heated to 620℃ to make the internal core temperature reach about 620℃. At this time, all the nickel sulfide in the glass is in the high-temperature α-NiS phase (hexagonal crystal).

[0043] Generally, the state of nickel sulfide in glass is as follows: when the temperature exceeds 1000℃, any NiS in the glass melt will form tiny droplets; when the glass cools to 797℃, these small droplets crystallize and solidify, and the nickel sulfide is in the high-temperature α-NiS crystal phase, with its diameter usually between 0.1 - 0.4mm, and some are even less than 0.06mm; when the temperature continues to drop to 379℃, the crystal phase transforms into the low-temperature β-NiS (trigonal system), accompanied by a 2.38% volume expansion. The speed of the crystal form transformation process depends not only on the percentage content of different components in the NiS particles but also on the surrounding temperature. If the NiS phase transformation is not completely converted, this process will still continue even under the temperature conditions of natural storage and normal use, but at a very low speed.

[0044] During the tempering process, since the glass enters the air grid and is rapidly cooled, the nickel sulfide undergoes a phase change at 379℃, but the rapid cooling time is short, and it fails to transform into the low-temperature β-NiS and is "frozen" in the glass in the high-temperature α-NiS phase.

[0045] Glass is inherently brittle, resistant to pressure but not to tension. Rapid cooling causes the glass to enter a state of equilibrium between external pressure and internal tension, resulting in surface compressive stress of approximately 100 MPa and internal tensile stress of approximately 45 MPa. In tempered glass, the NiS phase transition continues at a slow rate, expanding in volume and exerting a correspondingly greater force on the surrounding glass. The tempered glass core itself is a tensile stress layer. The volume expansion of the NiS within this tensile stress layer during the phase transition also creates tensile stress. The combined effects of these two tensile stresses multiply the stress, triggering spontaneous explosion of the glass. Even if the glass does not spontaneously explode, the presence of α-NiS in the surface compressive stress layer can significantly reduce the tempering strength. Experiments have shown that nickel sulfide with a diameter greater than 0.06 mm in the tensile stress layer can trigger spontaneous explosion. Over 95% of spontaneous explosions are caused by nickel sulfide particles between 0.04 mm and 0.65 mm, with an average particle size of 0.2 mm.

[0046] To further reduce the self-explosion rate, the ice crystal blue tempered glass is subjected to a hot dip homogenization treatment. The principle of the hot dip homogenization treatment is to utilize the crystal phase transition characteristics of nickel sulfide at different temperatures. The tempered glass is heated to 260℃±10℃ and kept warm for 2 hours. During the tempering process, the α-phase nickel sulfide at high temperature fails to transform into the low-temperature stable β-phase due to rapid cooling. During use, the metastable α-phase at room temperature will slowly transform into the stable β-phase, accompanied by about 4% volume expansion, leading to self-explosion. The hot dip homogenization treatment accelerates the transformation of nickel sulfide from α-phase to β-phase by heating to 260℃±10℃, so that glass that may self-explode will be broken in advance in the hot dip furnace of the factory. The time of the hot dip homogenization treatment is determined according to the thickness of the glass and the nickel sulfide content. In this embodiment, ice crystal blue tempered glass with a thickness of 8mm is selected, and keeping warm for 2 hours can ensure sufficient phase transformation of nickel sulfide. After hot-dip homogenization treatment, the self-explosion rate of ice blue tempered glass drops from 10ppm to below 1ppm, which is much lower than the 1-3‰ of ordinary tempered glass and 1‰ of ultra-white tempered glass.

[0047] Finally, an LED display layer was placed on the heat-dip homogenized ice blue tempered glass. The LED display layer included LED lamp beads and a driver circuit. The LED lamp beads were evenly fixed to the ice blue tempered glass surface with a high-temperature-resistant adhesive and connected to the driver circuit, creating a near-zero self-explosion video photoelectric glass. The video photoelectric glass produced in this embodiment exhibited an extremely low self-explosion rate in practical applications, effectively reducing the cost of patch replacement due to self-explosion.

[0048] Example 1

[0049] A method for preparing near-zero self-explosion video photoelectric glass, the specific implementation steps are as follows:

[0050] First, select the ice crystal blue glass sheet as the base material, with a self-explosion rate of one in one hundred thousand (10 ppm). The ice crystal blue glass sheet is produced through the glauber's salt clarification process to reduce the residual sulfur content in the glass, thereby reducing the formation of nickel sulfide (NiS) impurities. The reaction of glauber's salt (Na2SO4) during the glass melting process is divided into three stages: In the first stage, under a reducing atmosphere, glauber's salt begins to decompose at 400 °C and the reaction becomes intense at 500 °C, generating Na2S and sulfides. The chemical equation is:

[0051] Na2SO4 + 2C → Na2S + 2CO2↑;

[0052] Na2S + Na2SO4 + 2SiO2 → 2Na2SiO3 + SO2↑ + S↑ (865 °C);

[0053] In the second stage, at high temperatures (1200 °C - 1300 °C), glauber's salt decomposes into SO2 and O2 to achieve glass liquid clarification. The chemical equation is:

[0054] 2Na2SO4 → 2Na2O + 2SO2↑ + O2↑;

[0055] 2Na2SO4 + 2SiO2 + C → 2Na2SiO3 + CO2↑ + 2SO2↑ (720 °C - 1000 °C);

[0056] In the third stage, under an oxidizing atmosphere, SO2 reacts with O2 to form SO3, further improving the clarification quality. The chemical equation is:

[0057]

[0058] O 2- + SO3 = SO4 2- .

[0059] To optimize the clarification effect, control the atmosphere in the melting furnace so that it is a weakly reducing atmosphere near the hot spot and a weakly oxidizing atmosphere after the hot spot to reduce the sulfur solubility.

[0060] Subsequently, temper the ice crystal blue glass sheet to make ice crystal blue tempered glass. During the tempering process, the glass is heated to 620 °C to make the internal core temperature reach about 620 °C, and then rapidly cooled through the air grille to make the glass form a stress balance state with external compressive stress and internal tensile stress. The surface compressive stress is about 100 MPa, and the internal tensile stress is about 45 MPa.

[0061] To further reduce the spontaneous explosion rate, the Ice Blue tempered glass was subjected to a heat-dip homogenization treatment. The tempered glass was heated to 260°C and held at this temperature for two hours. In this example, 8mm thick Ice Blue tempered glass was used. Holding the glass for two hours ensured sufficient phase transformation of the nickel sulfide. After the heat-dip homogenization treatment, the spontaneous explosion rate of the Ice Blue tempered glass was reduced from 10ppm to below 1ppm.

[0062] Finally, an LED display layer is set on the ice crystal blue tempered glass that has undergone heat-dip homogenization treatment to produce near-zero self-explosion video photoelectric glass.

[0063] like Figure 4 and Figure 5 As shown, this photovoltaic glass comprises a multi-layer structure. Its core structure includes two outer layers of encapsulating glass, an LED display assembly and an integrated power board sandwiched between them, and a junction box and cable connector located on the top. Both outer layers of encapsulating glass are tempered from raw ice crystal blue glass, which boasts excellent raw material purity control and impurity suppression, resulting in a self-destruction rate as low as one in 100,000. After tempering, the glass undergoes a further heat-dip homogenization treatment, which involves holding it at 260°C ± 10°C for a period of time. This causes potential nickel sulfide impurity particles within the glass to undergo a crystalline transformation from α to β phase, thereby prematurely releasing volume expansion stress and effectively detonating potentially hazardous glass sheets. This results in a final product with a self-destruction rate of less than one in a million, achieving a near-zero self-destruction risk.

[0064] In terms of structural layout, the upper end of the photovoltaic glass is equipped with a junction box and cables for power input and signal connection. In the glass structure shown on the front, two pieces of tempered encapsulated glass form a sandwich space, in which a number of LED lamp beads and controllers are arranged evenly to realize the display function, and the controller performs logical scheduling and driving of the display content. Located behind the LED lamp beads and controller is an integrated power board, which provides constant current power to the lamp bead assembly through a preset electrical connection method and achieves stable output. The LED display assembly and the power board are both fixed to the inner surface of the glass with adhesive and are securely encapsulated inside by the front and back layers of glass, forming a structurally stable and airtight display unit.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.

[0066] Finally, the above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
