Insulating Glass argon filling detection technology

Whether the chamber is filled with argon gas and the content of argon gas has a great influence on the heat transfer coefficient K value, and has a certain influence on the shading coefficient Sc and the relative heating RHG, but the influence is slightly smaller. In addition, Low-E film, especially offline Low-E film, can be well protected after being filled with inert gas, making it more durable and extending the service life of Insulating Glass. At the same time, the sound insulation performance of the glass filled with inert gas will be improved. After being filled with inert gas argon, the heat transfer coefficient value of Insulating Glass is lower than that of vacuum state
It is 5% lower, and the insulation performance is better.

First of all, the detection system of the Insulating Glass argon filling equipment is used for detection and control. At present, some domestically produced gas filling equipment use gas sensors as the detection and control unit. The test of this inflatable device can fully meet the test requirements. (Some are particularly cheap
Of inflators do not use gas sensors for detection, although this equipment is sold very cheaply. But it cannot meet the requirements of accurate measurement).

The second is to use an inert gas detector for qualitative detection
The high-voltage electric spark from the inert gas detector probe directly touches the surface of the insulating glass. If the spark can pass through a layer of glass and enter the hollow Insulating Glass, it is an Insulating Glass filled with argon. Electric sparks can only be generated on the surface of insulating glass that is not filled with argon. This detection method is mainly for qualitative customers. This method can also be used as a simple test to determine whether the Insulating Glass is inflated.

The third is the detection of Insulating Glass inert gas detector
Insulating Glass inert gas detector is mainly used for contact quantitative detection of argon content in Insulating Glass. The accuracy of this instrument is generally within plus or minus one percent. This kind of measuring instrument will not bring loss to the pressure and gas content inside the Insulating Glass. It is an economical and practical detection method, which is generally used for random inspection in the production process of the Insulating Glass production line.
