Embodiment Construction

[0027] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0028] The invention provides a method for coating a viscous quartz crystal probe of a lunar dust measuring instrument, which specifically includes the following steps:

[0029] Step 1, fixedly install the quartz crystal on such as figure 1 In the coating tooling shown.

[0030] Step 2, cleaning the quartz crystal.

[0031] Due to the good volatility and solubility of petroleum ether, there is no residue after cleaning with petroleum ether. Therefore, petroleum ether is used to clean the quartz crystal. Soak the cotton swab with petroleum ether, starting from the center of the viscous quartz crystal, rotate the cotton swab clockwise to clean the surface of the quartz crystal; replace the clean cotton swab and repeat three times; during the cleaning process, use light and uniform force to prevent crushing the quartz crystal. After cleaning, let stand for...

Abstract

The invention discloses a method for coating a sticky quartz crystal (SQCM) probe of a lunar dust measuring instrument. By using the method, a quartz crystal can be coated with vacuum grease, and the sticky quartz crystal formed after coating is carried out can be used for measuring lunar dust. According to the method, at first, petroleum ether is adopted for cleaning the quartz crystal, and the quartz crystal with the frequency within 9990000 Hz-9995000 Hz is selected for being coated; Apiezion H grease is adopted as laminating of the sticky quartz crystal for carrying out coating, the frequency of the quartz crystal is monitored in the coating process, the frequency difference of the quartz crystal before and after coating is carried out is about 2 MHz, coating is finished, a Q value, resonance impedance and dynamic capacity of the quartz crystal are detected, and if the Q value, the resonance impedance and the dynamic capacity meet the technical indexes, the quartz crystal can be applied to the sticky quartz crystal probe.

Description

technical field [0001] The invention relates to the technical field of space environment dust measurement, in particular to a method for coating a sticky quartz crystal (SQCM) probe of a moon dust measuring instrument. Background technique [0002] The lunar dust measuring instrument is an engineering parameter measurement device on the CE-3 lander of the second phase of the lunar exploration project. It has been launched to the surface of the moon and is working in orbit. The lunar dust measuring instrument includes two probes, one SQCM probe and one solar cell probe. The SQCM probe mainly measures the amount of lunar dust accumulated on the lunar surface over a long period of time, and monitors changes in the volume and quality of the lunar dust; the solar cell probe mainly measures the amount of lunar dust splashed when the lander lands on the lunar surface. It is the first time in the world to use the SQCM probe to measure the accumulated amount of lunar dust on the lun...
