Description
Technical Field
[0001] The invention belongs to the field of manufacturing laminated vacuum heat-insulating light-transmitting tempered glass plates. Background Art
[0002] At present, the mainstream functional glass are insulating glass and vacuum glass.
[0003] The thermal insulation performance of hollow glass is not ideal, because the two layers of glass do not support each other and cannot borrow strength from each other, making the glass's ability to resist wind pressure weak and easily broken due to glass resonance.
[0004] Vacuum glass relies on the special structure of the vacuum layer to effectively block the heat conduction between indoor and outdoor areas. It can significantly reduce the power consumption of air conditioners, the emission of pollutants and greenhouse gases, and reduce environmental pollution.
[0005] Choosing vacuum glass with an appropriate shading coefficient can effectively control solar heat gain and keep the room cool in summer; in winter, when the outdoor temperature is -20℃, the inner surface temperature of the vacuum glass is only 3-5℃ lower than the indoor air temperature, which can keep the room warm and comfortable.
[0006] With the increasing density of urban population and the increase of transportation vehicles, noise pollution is becoming increasingly serious, which directly harms people. The vacuum layer of vacuum glass can effectively block the transmission of sound, especially for the medium and low frequencies with strong penetration, the effect is very significant.
[0007] The interior of vacuum glass is in a vacuum state and is not affected by the ambient air pressure, making it suitable for use in areas of all altitudes. At the same time, vacuum glass can maintain its excellent performance when used in various locations of a building, including facades, slopes and roofs. There is no problem of increased gas convection leading to reduced performance when the insulating glass is laid flat, but vacuum glass is not tempered glass.
[0008] Vacuum glass is made of two layers of glass panels with internal support, and the periphery is bonded by hot-melt low-temperature glass sealing adhesive and vacuumed and sealed. Vacuum glass is currently the most energy-saving transparent functional glass. It has a series of advantages such as light weight, thin thickness, low heat transfer coefficient, and good sound insulation effect. It is an ideal energy-saving building material. However, due to its high production cost and the inability to meet the safety requirements of tempered glass required by high-rise buildings, it has not yet been widely used. However, since the sealing adhesive bonding of vacuum glass periphery is low-temperature glass melting and sealing, its manufacturing process, cost, yield rate, mechanical properties and size specifications are greatly limited, and it is difficult to achieve tempering of glass panels, which affects the strength and safety performance of the glass. Once the glass melting and sealing edge is damaged and leaks due to stress and other reasons, the entire vacuum glass will lose its good sound insulation and thermal insulation properties.
[0009] The above-mentioned shortcomings of existing vacuum glass are caused by its design structure and production process. Existing vacuum glass is that two glass sheets are separated by a tiny support matrix, the periphery is sealed with low-melting-point glass material, and the glass exhaust pipe is used to "exhaust" and then sealed to form a vacuum layer with a pressure lower than 0.1Pa and a thickness of only 0.1-0.3mm. Therefore, the production of vacuum glass must be completed through multiple processes, including: 1) exhaust port drilling, 2) support placement, 3) glass brazing material coating, 4) glass assembly, 5) high-temperature edge sealing / exhaust port brazing, 6) high-temperature exhaust / sealing, and 7) getter unsealing.
[0010] The above-mentioned high-temperature edge sealing process is the main reason why existing vacuum glass cannot meet the safety standards of high-rise buildings. The standard requires that glass components of high-rise buildings must be made of tempered glass. However, because the melting temperature of the existing high-temperature edge sealing glass brazing material exceeds 550℃, which is much higher than the annealing temperature of conventional tempered glass of 388℃, even if tempered glass is used to make vacuum glass, it will be annealed into ordinary glass during the edge sealing process.
[0011] The applicant [Liu Weijie] applied for "A low-cost tempered vacuum glass and its manufacturing method" application number CN200910188347.2
[0012] This application provides a vacuum glass and a manufacturing method thereof, which uses a micro-bump support integrated with the glass original sheet to replace the existing stainless steel support placement process, uses a low-temperature metal tin brazing technology that will not cause annealing of the tempered glass original sheet for edge sealing, and simply integrates the traditional vacuum layer exhaust process and the edge sealing process into an integrated exhaust and edge sealing process.
[0013] Compared with the existing vacuum glass and its manufacturing process, this application completes vacuuming and brazing sealing at one time, and the safety reaches the standard for use in high-rise buildings. However, due to the need to apply expensive molten gold for sintering, the low temperature of tin brazing, the low heating temperature of the vacuum furnace, the insufficient degassing of glass and tin brazing material, the poor vacuuming effect, the low vacuum degree of the glass vacuum interlayer, etc., the thermal insulation and sound insulation performance of the vacuum glass are not satisfactory.
[0014] The technical solution of "A Glass and Metal Vacuum Brazing Process" application number CN200910234678.5 applied by the applicant [Nanjing University of Technology] requires chemical copper electroplating metal surface treatment on the glass surface based on the original process. After starting the heating system, the workpiece needs to be heated to 550°C with the furnace and kept warm until the vacuum degree in the furnace is 4×10-2Pa, so that the temperature of each part of the workpiece is uniform. In addition, the temperature in the brazing furnace needs to be continued to be raised to the brazing temperature, and the heating needs to be stopped after keeping warm for 10 to 30 minutes, and the vacuum glass needs to be slowly cooled with the furnace. The temperature of the vacuum glass out of the furnace is below 50°C.
[0015] As we all know, glass is an insulator and cannot conduct electricity under normal conditions, but the situation changes at high temperatures (above 500°C). Glass is a transparent solid, a semi-liquid substance that forms a continuous network structure when melted, and its viscosity gradually increases during cooling and hardens without crystallizing. It is a silicate. The higher the temperature of the glass, the greater the voltage across the glass, and the stronger the conductivity of the glass. There are two factors that cause the glass to conduct electricity, one is high temperature and the other is voltage. Of course, high temperature is the most important factor. The so-called conductor and insulator refers to the distinction between the conductive properties of materials under normal conditions. Under abnormal conditions, some insulators can conduct electricity. High temperature allows electrons in the glass to break free from the constraints of atoms to form free electrons, thus having the ability to conduct electricity. The voltage across the two ends causes the glass to be ionized under high temperature, thereby conducting electricity. The higher the temperature of the glass, the higher the voltage across the two ends, and the stronger its conductivity. Summary of the invention
[0016] The present invention utilizes the property that after the edge of the tempered glass is heated, the tempered glass will change from an insulator to a conductor, and realizes the resistance welding of the tempered glass by applying a voltage on both sides of the tempered glass. Thus, in the absence of other dielectric materials as brazing flux, the resistance heat capacity welding of the raw materials is realized, thereby achieving the advantages of tempered glass hot melt welding, such as stable performance, low cost, simple process, low stress, etc.

Three groups of power supplies are supplied alternately, and the power supplies on the two electric heating rollers are arranged on the diameter of the rollers, and heat is generated by the rollers' own resistance, and the heat is transferred to the two glass plates through conduction, so that the temperature of the glass plates increases and conducts electricity. The resistance heat-melting welding power supply is arranged on the opposite sides of the two glass plates, and the glass plates are electrically heated and welded. When the glass changes from solid to soften, it gradually changes from an insulator to a semiconductor and a conductor.

Therefore, the glass will melt due to conduction, and a good glass hot-melt welding between the glass and the glass will be achieved.

The electric heating resistance hot melt welding roller wire welding welds two tempered glass plates together. After the glass resistance hot melt welding, the temperature rises and the glass resistance becomes smaller. When the voltage remains unchanged, the current will increase. Therefore, a ballast is provided on the glass resistance hot melt welding circuit. The electric heating resistance hot melt welding roller is provided with a heat preservation device.
