Description

Glass stretching support frame and stainless steel frame and metal brazing vacuum control glass Technical field

The invention relates to using vacuum brazing technology to braze and seal glass and metal to manufacture a functional vacuum glass plate. It belongs to the field of glass building materials.

Background technique

At present, the mainstream of functional glass is insulating glass and vacuum glass.

technical problem

Insulating glass insulation performance is not ideal, because there is no mutual support between the two layers of glass, can not rely on each other, making the glass weak resistance to wind pressure, easy to break due to glass resonance. At the same time, because there is no protective frame around the insulating glass, it is easy to break the insulating glass due to bumping the glass corners during transportation and installation.

Vacuum glass is supported by sandwiching two layers of glass plates, and the periphery is sealed and sealed by sealing and adhesive bonding. Vacuum glass is the best transparent energy-saving vacuum glass at present. It has a series of advantages such as light weight, thin thickness, small heat transfer coefficient and good sound insulation effect. It is an ideal energy-saving building material. However, because of its expensive production cost and the inability to meet the safety requirements of toughened glass required by high-rise buildings, it has not yet been applied on a large scale. Because the sealing adhesive around the vacuum glass is bonded to a low-temperature glass fusion seal, its manufacturing process, cost, yield, mechanical properties and size specifications are greatly restricted, and it is difficult to achieve the tempering treatment of the glass plate. The glass strength and safety performance are affected. Once the glass frit edge is damaged due to stress and other reasons, the entire vacuum glass will lose good sound insulation and thermal insulation performance.

And connect the compression electric clip to the stainless steel frame wrapped outside the junction of the "mountain" shaped closed-loop aluminum or aluminum alloy frame, and connect another compression electric clip to another point at an equal distance from the stainless steel frame to form a package Two conductive loops with equal glass frame resistance. Close the vacuum brazing furnace door, heat and evacuate the hollow laminated glass sheet blank in the vacuum brazing furnace. When the heating temperature, vacuum degree and set vacuum time are reached, the two compact electric clamps on the hollow laminated glass sheet blank Connect low-voltage, high-current heating power supply.

Since the resistance of the aluminum or aluminum alloy frame among the three of the stainless steel frame, glass, aluminum or aluminum alloy frame is the smallest, the current in the aluminum or aluminum alloy frame is the largest, the aluminum or aluminum alloy frame quickly heats up, and itself quickly heats up and melts evenly. Under the capillary action of the contact gap between stainless steel and glass, glass and glass, stainless steel and stainless steel, and the cohesion of the brazing material after melting, the molten brazing material and glass brazing surface and stainless steel brazing surface are fully immersed and wetted To realize the brazing of aluminum paste to the glass surface and stainless steel surface.

In this process, aluminum quickly heats up and turns into liquid aluminum, and the glass brazed with stainless steel and aluminum is not completely softened due to its poor thermal conductivity and short heating time. At 720℃, the main component of the glass, Si02 and Al, has a chemical reaction: 4A1+3Si0 ₂ = 2A1 ₂ 0 ₃ +3Si, that is, the interface between the glass and aluminum can be firmly bonded due to the chemical reaction. At the same time, at 720°C, the stainless steel is not softened, and the surface of the oxide layer of the stainless steel reacts with aluminum, that is, the interface between the stainless steel and aluminum is also firmly bonded due to the chemical reaction. However, after all, the temperature of 720°C is already the softening temperature of ordinary glass. Therefore, if the brazing temperature is lowered, it not only ensures that the glass is not significantly softened, but also meets the process requirements. Aluminum alloy brazing material is used to reduce the brazing temperature between the glass and stainless steel frame, improve the brazing quality between glass and stainless steel, and reduce the difficulty of the brazing process.

Although aluminum or aluminum alloy brazing material has good cutting properties, considering that the linear expansion coefficients of glass and aluminum or aluminum alloy brazing material differ greatly, in the cooling process, due to inconsistent shrinkage, it will be on the brazed surface A certain amount of stress is generated. Therefore, the stainless steel frame is deformed as much as possible to absorb the stress caused by the thermal expansion and contraction of the aluminum or aluminum alloy brazing material to ensure the brazing quality between the stainless steel frame and the glass.

At the same time, due to the deeper design of the U-shaped closed-loop stainless steel frame groove, the corresponding closed-loop aluminum or aluminum alloy frame is also longer, so the brazed connection sealing layer formed is thicker, making the aluminum or aluminum alloy and glass It has high brazing strength with stainless steel and good airtight sealing performance.

After the aluminum or aluminum alloy frame is heated and evenly melted, the resistance will suddenly increase and the current will instantly decrease. Therefore, this phenomenon can be used to automatically and intelligently control the energized heating time, accurately control the brazing temperature, and achieve good vacuum brazing of aluminum or aluminum alloys with flat glass and stainless steel frames.

When the brazing heating power is cut off in time, the aluminum paste brazing layer cools down, and gradually forms a temperature field with glass and stainless steel frame that tends to be consistent, and achieves a good brazing connection. After that, water is directly sprayed into the vacuum brazing furnace, so that the water evaporates and vaporizes in a vacuum state to generate air pressure, and the exhaust check valve provided on the mouth of the connected sealing pipe is instantly closed. Under the action of air pressure, the stainless steel frame quickly compacts the softened aluminum paste brazing layer and allows it to exotherm and solidify, and realizes a rapid and sharp cooling of the vacuum brazing furnace. Since stainless steel and aluminum paste are good thermal conductors, And the edge of the glass is wrapped with aluminum paste brazing material, so it can make the glass in the stainless steel frame evenly radiate heat and cool down, so that the glass in the stainless steel frame is tempered, after that, air is introduced, or the vacuum brazing furnace is opened The cooling device is provided to cool the vacuum brazing furnace.

Or when the brazing heating power is cut off in time, the aluminum paste brazing layer cools down, and gradually forms a temperature field with glass and stainless steel frame temperature tending to be consistent, and achieves a good brazing connection. After that, the vacuum brazing furnace is ventilated with air, and the exhaust check valve provided at the mouth of the joint sealing pipe fitting is instantly closed. The air absorbs heat and expands to produce pressure. Under the action of air pressure, the stainless steel frame quickly compacts the softened aluminum paste brazing layer and allows it to radiate and solidify. After that, spray water to the vacuum brazing furnace to make the water absorb the air heat Reduce the temperature of the vacuum brazing furnace to make the glass in the stainless steel frame moderately tempered. After that, or turn on the cooling device provided in the vacuum brazing furnace to cool the vacuum brazing furnace.

Or when the brazing heating power is cut off in time, the aluminum paste brazing layer cools down, and gradually forms a temperature field with glass and stainless steel frame temperature tending to be consistent, and achieves a good brazing connection. After that, the vacuum brazing furnace is ventilated with air, and the exhaust check valve provided at the mouth of the joint sealing pipe fitting is instantly closed. The air absorbs heat and expands to produce pressure. Under the action of air pressure, the stainless steel frame quickly compacts the softened aluminum paste brazing layer and allows it to radiate and solidify. After that, the hot air is released and cold air is filled to braze the vacuum. Cool the furnace, or turn on the cooling device in the vacuum brazing furnace to cool the vacuum brazing furnace. The aluminum paste brazing material in the stainless steel frame will naturally cool and solidify, causing the glass in the stainless steel frame to lose its tempering characteristics.

Through the above process, the quality of glass and stainless steel brazed by aluminum paste is improved, and the characteristics of the glass in the tempered glass stainless steel frame are changed, so that the flat glass within the inner edge of the closed-loop stainless steel frame is still tempered glass, or wrapped in the closed-loop stainless steel frame groove The glass is moderately tempered, or the glass wrapped in the closed-loop stainless steel frame groove loses the tempering characteristics, and has the function of regulating the vacuum degree of the vacuum interlayer.

When the temperature of the vacuum brazing furnace is reduced to 50°C-55°C, the door of the vacuum brazing furnace is opened, and finally a vacuum-regulated thermal insulation glass plate is obtained by vacuum electrothermal brazing of glass plates and glass plates and stainless steel frames and aluminum paste.

Two glass edge blanks are produced, which are wrapped with a closed-loop aluminum paste brazing film layer, and closely fit with a stainless steel closed-loop protection frame, and the hollow laminated glass plate blank is dried.

After that, at least one blank of the glass plate is sent into a vacuum brazing furnace, heated and evacuated, and electrically brazed to achieve vacuum brazing of the stainless steel frame, aluminum or aluminum alloy and glass, and unsealing the long-acting getter. After the vacuum brazing furnace is ventilated and cooled, the furnace is opened, and the glass tensile supporting frame, the stainless steel frame and the metal brazing vacuum control glass are prepared.

A method for manufacturing glass stretching support frame, stainless steel frame and metal brazing vacuum control glass, including glass plate, aluminum or aluminum alloy brazing profile, stainless steel frame, vacuum brazing furnace. Between the two glass plates, a hollow interlayer is separated by a supporting frame. The two glass plate sealing covers and the surface and the edge of the glass plate are provided with aluminum or aluminum alloy brazed profiles. The aluminum alloy brazed profile frames are wrapped with stainless steel frames , Made into hollow laminated glass blank.

After that, at least one hollow laminated glass sheet blank is placed horizontally in a vacuum brazing furnace provided with a supporting base, a fixed supporting jig or a tray. The glass tray of the brazing furnace may be provided with an ultrasonic transducer for improving the brazing quality of glass to glass, glass to metal, and metal to metal. And connect the compact electric clip to the stainless steel frame wrapped in the outer shape of the U-shaped closed-loop aluminum paste brazing film layer, and connect another compact electric clip to the stainless steel frame at another point at an equal distance to form a wrapped glass frame Two conductive loops with equal resistance. Close the vacuum brazing furnace door, heat and evacuate the hollow laminated glass sheet blank in the vacuum brazing furnace. When the heating temperature, vacuum degree and set vacuum time are reached, the two compact electric clamps on the hollow laminated glass sheet blank Connect low-voltage, high-current heating power supply.

Since the resistance of the aluminum paste brazing film layer among the three of the stainless steel frame, glass, and aluminum paste brazing film layer is the smallest, the current in the aluminum paste brazing film layer is the largest, the aluminum paste brazing film layer rapidly heats up, and itself quickly heats up Melt evenly. Under the capillary action of the contact gap between stainless steel and glass, glass and glass, stainless steel and stainless steel, and the cohesion of the brazing material after melting, the molten brazing material and glass brazing surface and stainless steel brazing surface are fully immersed and wetted To realize the brazing of aluminum paste to the glass surface and stainless steel surface.

During this process, the aluminum paste brazing material quickly heats up and becomes liquid aluminum, while the glass brazed with stainless steel aluminum paste is not fully softened due to its poor thermal conductivity and short heating time. At 720℃, the main component of the glass, Si02 and Al, has a chemical reaction: 4A1+3Si0 ₂ = 2A1 ₂ 0 ₃ +3Si, that is, the interface between the glass and aluminum can be firmly bonded due to the chemical reaction. At the same time, at 720°C, the stainless steel is not softened, and the surface of the oxide layer of the stainless steel reacts with aluminum, that is, the interface between the stainless steel and aluminum is also firmly bonded due to the chemical reaction. However, after all, the temperature of 720°C is already the softening temperature of ordinary glass. Therefore, if the brazing temperature is lowered, it not only ensures that the glass is not significantly softened, but also meets the process requirements. Aluminum alloy brazing material is used to reduce the brazing temperature between the glass and stainless steel frame, improve the brazing quality between glass and stainless steel, and reduce the difficulty of the brazing process.

Although the aluminum paste brazing material has good cutting properties, considering that the linear expansion coefficients of glass and aluminum paste brazing material are very different, in the cooling process, due to inconsistent shrinkage, a certain stress will be generated on the brazed surface. Therefore, the stainless steel frame is deformed as much as possible to absorb the stress caused by the thermal expansion and contraction of the aluminum paste brazing material to ensure the brazing quality between the stainless steel frame and the glass.

At the same time, due to the deeper design of the U-shaped closed-loop stainless steel frame groove, the corresponding closed-loop aluminum paste frame is also longer, so the formed brazing connection sealing layer is thicker, making the aluminum paste braze with glass and stainless steel High strength and good airtight sealing performance.

After the aluminum paste frame heats up and melts evenly, the resistance will suddenly increase and the current will instantly decrease. Therefore, this phenomenon can be used to automatically and intelligently control the heating time of energization, accurately control the brazing temperature, and realize the vacuum brazing of aluminum paste, flat glass, and stainless steel frame.

When the brazing heating power is cut off in time, the aluminum paste brazing layer cools down, and gradually forms a temperature field with glass and stainless steel frame that tends to be consistent, and achieves a good brazing connection. After that, water is directly sprayed into the vacuum brazing furnace, so that the water evaporates and vaporizes in a vacuum state to generate air pressure, and the exhaust check valve provided on the mouth of the connected sealing pipe is instantly closed. Under the action of air pressure, the stainless steel frame quickly compacts the softened aluminum paste brazing layer and allows it to exotherm and solidify, and realizes a rapid and sharp cooling of the vacuum brazing furnace. Since stainless steel and aluminum paste are good thermal conductors, And the edge of the glass is wrapped with aluminum paste brazing material, so it can make the glass in the stainless steel frame evenly radiate heat and cool down, so that the glass in the stainless steel frame is tempered, after that, air is introduced, or the vacuum brazing furnace is opened The cooling device is provided to cool the vacuum brazing furnace.

Or when the brazing heating power is cut off in time, the aluminum paste brazing layer cools down, and gradually forms a temperature field with glass and stainless steel frame temperature tending to be consistent, and achieves a good brazing connection. After that, the vacuum brazing furnace is ventilated with air, and the exhaust check valve provided at the mouth of the joint sealing pipe fitting is instantly closed. The air absorbs heat and expands to generate pressure. Under the action of air pressure, the stainless steel frame quickly compacts the softened aluminum paste brazing layer and makes it exothermic and solidifies. After that, spray water to the vacuum brazing furnace to make the water absorb the heat of the air Reduce the temperature of the vacuum brazing furnace to make the glass in the stainless steel frame moderately tempered. After that, or turn on the cooling device provided in the vacuum brazing furnace to cool the vacuum brazing furnace.

Or when the brazing heating power is cut off in time, the aluminum paste brazing layer cools down, and gradually forms a temperature field with glass and stainless steel frame temperature tending to be consistent, and achieves a good brazing connection. After that, the vacuum brazing furnace is ventilated with air, and the exhaust check valve provided at the mouth of the joint sealing pipe fitting is instantly closed. The air absorbs heat and expands to generate pressure. Under the action of air pressure, the stainless steel frame quickly compacts the softened aluminum paste brazing layer and allows it to radiate and solidify. After that, the hot air is released and cold air is filled to braze the vacuum. Cool the furnace, or turn on the cooling device in the vacuum brazing furnace to cool the vacuum brazing furnace. The aluminum paste brazing material in the stainless steel frame will naturally cool and solidify, causing the glass in the stainless steel frame to lose its tempering characteristics.

Through the above process, the quality of glass and stainless steel brazed by aluminum paste is improved, and the characteristics of the glass in the tempered glass stainless steel frame are changed, so that the flat glass within the inner edge of the closed-loop stainless steel frame is still tempered glass, or wrapped in the closed-loop stainless steel frame groove The glass is moderately tempered, or the glass wrapped in the closed-loop stainless steel frame groove loses the tempering characteristics, and has the function of regulating the vacuum degree of the vacuum interlayer.

Since stainless steel and aluminum paste are good thermal conductors, and the glass edge is wrapped with aluminum paste brazing material, it can make the glass in the stainless steel frame uniform Quickly release heat and cool down, so that the glass in the stainless steel frame is tempered, and then pass air or turn on the cooling device provided in the vacuum brazing furnace to cool the vacuum brazing furnace; Or when the brazing heating power is cut off in time, the aluminum paste brazing layer cools down, gradually forming a temperature field with glass and stainless steel frames that tend to be consistent in temperature, and achieving a good brazing connection; after that, the vacuum brazing furnace is ventilated with air , The exhaust check valve provided on the mouth of the Unicom sealing pipe is closed instantly; the air absorbs heat and expands to produce pressure, and the stainless steel frame quickly compacts the softened aluminum paste brazing layer under the effect of air pressure and makes it radiate heat After solidification, spray water to the vacuum brazing furnace to make the water absorb the heat of the air and cool the vacuum brazing furnace, so that the glass in the stainless steel frame is moderately tempered. After that, or turn on the cooling device provided in the vacuum brazing furnace. Vacuum brazing furnace cooling; Or when the brazing heating power is cut off in time, the aluminum paste brazing layer cools down, gradually forming a temperature field with glass and stainless steel frames that tend to be consistent in temperature, and achieving a good brazing connection; after that, the vacuum brazing furnace is ventilated with air , The exhaust check valve provided on the mouth of the Unicom sealing pipe is closed instantly; the air absorbs heat and expands to produce pressure, and the stainless steel frame quickly compacts the softened aluminum paste brazing layer under the effect of air pressure and makes it radiate heat After solidification, cool the vacuum brazing furnace by releasing hot air and charging cold air, or turn on the cooling device in the vacuum brazing furnace to cool the vacuum brazing furnace.
