How to Produce the Tempered Insulating Glass?

Tempered insulating glass is a glass product that uses an aluminum frame or extruder strip injected with desiccant to separate the glass between two or more pieces of tempered glass, and is sealed on all sides by sealing to keep argon-gas filling in the middle cavity at all times.

How to produce the tempered glass homogenization treatment
  • Principle of tempered homogenization treatment 
Homogenization tempering treatment is to heat the tempered glass to (290±10)℃ and keep it warm for a certain period of time, so that nickel sulfide can quickly complete the crystal phase transformation in the tempered glass, so that the tempered glass that would explode after use can be artificially broken in the homogenization furnace of the factory in advance, thereby reducing the self-explosion of tempered glass in use after installation.

  • Process of tempered homogenization treatment
1. Heating stage The heating stage starts at the ambient temperature of all glasses and ends when the surface temperature of the last glass reaches 280℃. The temperature in the furnace may exceed 310℃, but the temperature of the glass surface cannot exceed 320℃. The time when the glass surface temperature exceeds 300℃ should be shortened as much as possible.
2. Insulation stage The insulation stage starts when the surface temperature of all glasses reaches 280℃, and the insulation time is at least 2h. During the entire insulation stage, the temperature of the glass surface should be kept within the range of (290±10)℃.
3. Cooling stage When the glass that finally reaches 280℃ has been kept warm for 2h, the cooling stage begins, during which the glass temperature drops to the ambient temperature. When the temperature in the furnace drops to 70℃, the cooling stage is considered to be terminated.

8 steps to understand the process of insulating a glass machine

1. Bending of aluminum spacers: First, cut and bend the aluminum spacers into a shape of appropriate size according to the glass processing size requirements. This step is usually completed by automated bending equipment to improve production efficiency and reduce manual errors. At the same time, laser coding can be performed according to the OA work order system to identify the model. 

2. Filling of aluminum spacers: After the aluminum spacers are bent, the aluminum spacers are filled with adsorbents. Generally, a 3A molecular sieve is used as the adsorbent for filling. 

3. Low-E film layer detection: The film layer is detected through the Low-E Glass photoelectric detection switch in the feeding section to effectively prevent the Low-E Glass from being placed upside down. 

4. Washing and Drying: The cut glass blocks will go through the cleaning process to remove dirt, grease, and other impurities on the surface to ensure that the next process can proceed smoothly. Glass washing usually uses an efficient washing and drying machine, which can complete the cleaning of large quantities of glass in a shorter time. 

5. Inspection: The washed glass blocks need to undergo strict quality inspection to ensure that they meet the standards and requirements. The inspection process is usually carried out by manual visual observation, which can detect the flatness, thickness, surface defects, and whether the glass is clean. 

6. Assembly: The glass blocks that have passed the inspection will be sent to the insulating glass plate pressing segment for assembly. The insulating glass machine will automatically place two or more pieces of glass at the required interval and inflate them. 

7. Sealing: The assembled glass undergoes a sealing process to ensure that the gas or air in the insulated layer does not leak. Sealing generally uses high-efficiency sealants, such as hot melt sealant or structural sealant, and fully automatic sealing lines for sealant application. 

8. Inspection: Finally, the insulating glass is inspected again to ensure that the quality and performance meet the requirements. For example, glass appearance inspection, sealing test, thermal performance test, etc. can be carried out.

How to produce the insulating glass units: The Aluminum Spacer Strips Coating.
  • Assemble the Aluminum Spacer Strips 
According to the processing order, pick up the cut aluminum strips from the aluminum strip cutting process. Batch select aluminum strips for framing, install the pin connector at one end, and wipe it clean with a cloth dipped in xylene or alcohol. Put the aluminum strips with the pin connector installed and wipe clean on the molecular sieve desiccant filling device to fill the desiccant. Take down the aluminum strips filled with desiccant and place them on the work surface to assemble them into aluminum strip spacer frames. Hang or place the aluminum strip spacers in an orderly manner in a clean place.

  • Apply the Butyl Extruder Coating
Turn on the power of the butyl extruder coating machine and preheat the butyl extruder coated to the set temperature (or automatically preheat if the temperature was set when the machine was turned on last time). Start the synchronous belt and check whether the synchronous belt transmission speed and extrusion pressure need to be readjusted until they meet the requirements; Put one of the aluminum strip spacer frames into the distance adjustment device to measure the width of the aluminum strip. The distance between the sealant nozzles can be automatically adjusted according to the width of the aluminum strip; Each aluminum strip spacer frame is coated with sealant on the four sides and hung on the iron hook of the inspection frame sealing station.
How to produce the Insulating glass units: The Glass Pressing and Argon-gas Filling.
  • Check Frame Sealing and Glass Plate Pressing 
According to the process requirements, adjust the frame sealing positioning mechanism to ensure that the injection concentration meets the processing requirements. Start the frame gluing machine to check the aluminum sheet closing and switch to automatic operation. The glass automatically enters the upper frame section for inspection. Manually check whether the appearance of the glass meets the quality requirements. If it does not meet the requirements, it will be processed or taken off the line. After the first piece of glass passes the inspection, step on the switch to enter the plate pressing section; after the second piece of glass passes the inspection, seal the frame as required and step on the switch to the plate-pressing section. (When checking, please note that the Low-E coating surface is on the second side of the first piece of glass) The plate-pressing section is automatically closed inflated and extruded.

  • Automatic Sealing 
Start the automatic sealing robot line. When the assembly process is ready, start mixing the sealant until it is uniform, and then put the automatic control sealant sealing line into automatic operation. The assembled insulating glass enters the automatic sealing robot line, and the sealant sealing machine head starts to apply sealant. Check whether the sealing injection quality meets the requirements.
