Introduction

As the country's requirements for building energy efficiency increase, insulating glass is widely used in the field of building energy conservation as an energy-saving glass product. Inert The gas content has a direct impact on the energy-saving performance of the insulating glass. The gas content requirement has been included in the national standard for insulating glass, making the hollow glass The test method for the inert gas content of the glass is particularly important. There are many test principles and methods for the inert gas content of insulating glass. Some methods can be used for production process monitoring, and some methods can be used. Used for laboratory testing. This standard covers two methods for testing the inert gas content of insulating glass, namely. gas chromatography and Magnetic oxygen analysis. The tester may use any method of this standard to test the inert gas content in the insulating glass. But use different parties The test results of the inert gas content obtained by the law may be different, which is due to different test principles, so it is recommended. Mark the test results in the test report. Hollow glass inert gas content test method

1 Scope

This standard specifies the equipment, calibration, environmental conditions, samples, gas extraction points, and tests of the test method for the inert gas content of insulating glass. Process, inert gas content calculation formula and test report. This standard applies to the test of the inert gas content in the hollow glass chamber.

2 Normative references

The following documents are indispensable for the application of this document. For dated references, only dated versions apply to this article. Pieces. For undated references, the latest edition (including all amendments) applies to this document. JJG700 gas chromatograph verification procedure

3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Oxygen analysis methodhodoxygenanalysis By accurately testing the oxygen content in the mixed gas in the hollow glass chamber, according to the principle that the volume ratio of oxygen in the air is constant, In order to obtain the content of air in the mixed gas, a method of calculating the content of the inert gas is finally derived.

4 gas chromatography analysis

4.1 Principle Gas chromatography analysis utilizes the components in the sample gas, and the distribution and adsorption coefficient between the gas phase and the stationary phase in the column are not Similarly, when the carrier gas brings the sample gas into the column, the running speed of each component is different. After a certain column length, the color is colored in a different order. Separated in the column, entered the tester for testing, qualitative and quantitative analysis according to the retention time and response value of each component, and finally measured The content of each component of the sample gas. 4.2 Equipment 4.2.1 Gas chromatograph, qualified according to JJG700 and satisfying the following conditions. a) being capable of separating an inert gas from the mixed gas; b) having a thermal conductivity detector (TCD); c) Test accuracy is at least 0.1%. 4.2.2 A sampler with a volume of 50 mL, as shown in Figure 1. ......
