The Function of Insulating Glass Filled with Argon-gas

  1. Improve thermal insulation performance. Because inert gases have higher density and lower thermal conductivity than air, their performance is more stable. Therefore, it can slow down the heat convection in the middle layer and reduce the thermal conductivity of the gas. It can be seen that the higher the argon concentration, the better the insulation performance.
  2. Argon gas can bring the inner surface of the glass closer to room temperature, reducing the occurrence of condensation and making it less likely to cause condensation and frost in winter.
  3. Improve the safety of glass. The window glass area of modern buildings is large. If the hollow layer is uneven, the two layers of glass will be unevenly stressed under the action of atmospheric pressure and internal suction will occur. After filling with argon gas, the pressure difference between the inside and outside can be reduced, the pressure balance can be maintained, and the glass bursting caused by the pressure difference can be reduced.
  4. Argon is an inert gas that can effectively reduce resonance and greatly improve its sound insulation and noise reduction effect.
  5. Because the gas-filled is a dry inert gas, the air containing moisture in the insulating glass cavity can be replaced to keep the environment in the cavity dry and extend the service life of the molecular sieve in the aluminum spacer frame.
  6. When using low-emissivity Low-E glass or coated glass, since the filled gas is an inactive inert gas, it can protect the film layer, reduce the oxidation rate, and extend the service life of the glass.


Operation Steps

  1. Put the glass into the feeding section of the glass washing and drying machine, push the glass into the washing section by hand, and the glass will be washed and dried in the discharging section;
  2. Check the glass washng and drying quality in the discharging section;
  3. When the glass enters the laminating machine and reaches the end point close to the switch, the glass automatically stops at the positioning column;
  4. There is a foot switch at the end of the lamination machine. Step on the foot switch and the aluminum frame will be positioned and moved out. Position the glued aluminum frame and place it. Step on the foot switch again and the aluminum frame will be positioned and retracted;
  5. At the same time as the above step, after the second piece of glass has been cleaned and dried, it automatically stopped at the proximity switch at the end of the discharging section of the cleaning machine for use;
  6. Manually move the second piece of glass to the laminating machine and combine it with the first piece of glass;
  7. Press the start button of the roller laminating machine, and the laminated glass will automatically enter the roller laminating machine. After being rolled, the glass will reach the predetermined thickness size;
  8. The closed pieces of glass enter the turning table and automatically stop at the end of the turning table. Press foot switch 2 to release the flat material from the table.

The Air-floating Glass Transmission Section

At present, with the development of technology and market demand, the insulating glass format of glass curtain wall buildings continues to expand and its thickness continues to become thinner. Therefore, the production technology of the automatic insulating glass production line is required to be higher. At present, large-sized flat glass is mostly transported by contact transmission rollers. These contact methods can easily cause scratches and contamination to the flat glass, and can easily cause the glass to break, thus seriously affecting the quality of the product and thus the production efficiency.


Figure 1 The Air-floating Glass Transmission Section 1 Figure 1 The Air-floating Glass Transmission Section 1 

Based on the phenomena of scratches and contamination that often occur among glass deep processing practitioners, LIJIANG Glass independently developed and produced an air-floating glass transmission section, which is used for air-floating transportation of large-scale glass, including a bracket and an air-floating transportation platform installed on the bracket. , the air flotation conveying platform is assembled and spliced by several air flotation conveying plates; several floating holes are distributed on the air flotation conveying plate, and a conveying channel is opened inside the air flotation conveying plate, and the conveying channel runs through the side of the air flotation conveying plate, Each of the floating holes is connected to a transportation channel inside the air flotation transport platform; the floating holes are in the shape of a funnel with an upward opening, and diversion grooves are evenly provided around the edges. The new air-floating glass transmission section has a simple structure, easy processing, and flexible operation. Through airflow control, specific airflow distribution can be achieved to achieve air-floating lifting with uniform lifting force, stable load-bearing of large glass, and convenient transportation.

The External Plate Pressing Structure Section

Most of the insulating glass plate pressing structures currently in use use ball screws and hydraulic pressure. In the actual production process, most of the production line equipment and transportation structures require the insulating glass to be transported at an angle, resulting in subsequent plate pressing. The structure is also tilted. After long-term use, the plate-pressed structure is prone to metal fatigue, causing the insulating glass to collide with the plate-pressed structure, causing fragmentation and delaying production progress. Secondly, during the subsequent plate pressing process, the hydraulic pressure The mechanism and ball screw are easily prone to stroke deviation, resulting in uneven subsequent plate pressure, which may lead to loose sealing or fragmentation.


In response to this problem, LIJIANG Glass independently developed and produced an automated insulating glass outer sheet pressing production line using a plate pressing device. Through storage boxes, buffer rods, buffer springs, mounting blocks, balls, and negative pressure suction cups, it can ensure During the process of extrusion and transportation, the insulating glass is in a relatively stable state and will not be dislocated, which avoids the problem of loose sealing and improves the quality stability of the product. Through the limiting frame, limiting rollers, plate surface, and base, The working stroke of the limiting plate can be limited to avoid the problem of uneven force, which may lead to broken insulating glass or loose sealing.

LIJIANG Glass adopts the front and rear squeeze wheel drive, the front and rear wheels are powered, and glass of any size and thickness can pass through smoothly; like the drying section of the insulating glass production line of other manufacturers, some use supporting rollers, and the rear wheel is used as the driving wheel, and the front wheel is used as the driven wheel. These methods are easy to turn over when processing small-size glass, and easy to move when processing large-size glass, which affects the processing efficiency.
LIJIANG Glass uses a round-head Low-E Glass coating detection probe instead of a needle-type detection probe, which will not pierce the glass; it also does not use the photoelectric detection probe commonly used by other manufacturers. The disadvantage of photoelectric detection is that it encounters some high-transparency Low-E Glass is easy to detect the coating.
in the third section, one piece of 2.5-meter glass can be parked at the same time, and two pieces of 2-meter glass can be parked at the same time.
The glue depth of the aluminum frame installation of the upper frame section can be adjusted through the digital handle, which is simple and intuitive.
The fifth section, which could called the Flat Press Loading Section, measures the thickness of the glass and aluminum frame, mainly to provide accurate data for the sixth section of inflation and pressing, because the inflatable beam and the pressing section need servo motors to control the pressing distance, and the glass of the same specification does not need Measure glass thickness and aluminum frame thickness each time.
What structure is used by other manufacturers, and what are the advantages?

The inflatable beam and the conveyor belt in the pressure section of the LIJIANG Glass inflatable plate adopt an integrated synchronous belt structure. This method has better sealing performance, and the insulating glass is not easy to leak during the process of inflating and assembling; other manufacturers use a separate structure for the transmission wheel and the inflating beam. In this way, the bottom is prone to air leakage during the inflating and closing process.
The air hole in the pressure section of the LIJIANG Glass inflatable plate adopts the method of direct blowing air into the inside of the two pieces of glass, the argon-gas intake filling speed is faster, and the inflating effect is better when processing large-format glass; compared with other manufacturers, the air intake is reflected to the aluminum bar In the way of filling the inside of the two pieces of glass, the argon-gas intake filling speed is relatively slow. When processing large-format glass, the wide aluminum strip will block the flow of gas, and the gas filling concentration is difficult to reach the standard.
The plate pressing plate surface of the LIJIANG Glass inflatable plate pressing section can be adjusted individually, divided into 74 points for adjustment.
