Effect test
Embodiment 1
[0043] refer to figure 2 , four-in-one glue pollution component test
[0044] The test stable temperature is 125°C, and the test pressure is better than 1×10 -4 Pa. The test parameters used in the test are shown in the table below:
[0045] parameter name
[0046] Observe that the peaks of the four-in-one glue appear at positions 2, 18, 28, 29, 41, 43, 57, 77, 91, 105, 121, 149, 166, 205, 224, etc., among which the obvious point is at mass number 149 , its peak height is larger than that of water vapor, and after the heating is stabilized, it still maintains a considerable height. This shows that there are a lot of phthalates in the four-in-one glue, and some long-chain alkanes in the gas.
Embodiment 2
[0048] refer to image 3 , glue plus polluting component test
[0049] The conditions and parameters of the test were the same as in Example 1.
[0050] Mass spectrum peaks mainly appear in mass numbers 2, 12, 18, 28, 39, 41, 43, 73, 77, 91, 105, 121, 131, 149, 156, 179, 186, 224, 246, 254, etc., in the outgas The components include butane, butanone, isobutanol, aromatic aldehydes, propylbenzene, phthalates, etc. For several peaks with large mass numbers, it is difficult to determine their components, of which 156 and 254 are long-chain alkanes.
Embodiment 3
[0052] refer to Figure 4 , polyimide contamination component test
[0053] The conditions and parameters of the test were the same as in Example 1.
[0054] As can be seen from the figure, except for a large amount of water vapor, polyimide has very little outgassing.

Abstract
The invention discloses a detection method of the components of the gassing pollution of a non-metallic material used in a satellite, which is characterized in that the invention designs a sampling and sample storing system that can effectively detect the components of the gassing pollution of the non-metallic material used in the satellite under the simulated space environment. When in testing process, a sample is put in the sampling system, and the material under test completely generates gassing release action as fully as possible by the sample storing system, thus the detection system can fully detect the components of the gassing pollution. The detection method realizes the analysis of the gassing pollution from the qualitative aspect, overcomes single analyzing the gassing pollution from the quantitative pollution aspect in existence, effectively and deeply analyzes the gassing pollution of the non-metallic material used in the satellite and provides reference data for screening and processing the non-metallic material used in the satellite and carries out control and protection of satellite pollution from the aspect of pollution source.
Description
technical field [0001] The invention relates to a mass spectrometry detection method, in particular to a detection method for gas pollution components of non-metallic materials used in stars. Background technique [0002] During the operation of the aircraft in orbit, various space environmental effects will seriously affect its reliability and life. In the space environment, outgassing pollutants from non-metallic materials used in satellites may remain near the spacecraft, or may adhere to the surface of sensitive systems of the spacecraft. If these pollutants adhere to the surface of the spacecraft, or are within the observation field of view of the optical system of the spacecraft, they will produce different degrees of pollution effects, so it is necessary to study the components of air pollution. Foreign countries have already carried out work in this area, such as NASA in-depth The study analyzes the outgassing of aircraft coating Z306 in the space environment. Howe...
