CLDS-i模拟月尘的基本性质及应用前景

Basic Properties and Potential Application of CLDS-i Lunar Dust Simulant

月尘对航天器、航天服性能和航天员的健康存在的危害迫切需要解决,在月尘样品稀缺的条件下,具有很高相似性的CLDS-i模拟月尘是开展尘埃防护技术攻关和毒性机理研究的重要基础。CLDS-i模拟月尘含75%玻璃组分和少量纳米金属铁颗粒,中值粒径为500~600 nm,具有复杂粒形和锋利棱角,其基本性质与实际月尘相似,可应用于月尘科学研究、月尘治理技术、月尘毒理学研究等诸多领域。

Lunar dust can make serious d amages to the space pr o b e, the space suit, and the health of astronaut, which is one of the key challenges faced in the m a n n e d lunar exploration. D u e to the rareness of the lunar dust samples, CLDS-i lunar dust simulant with high similarity to the real lunar dust is an important basis for the study of the lunar dust protection and dust toxicity. T h e CLDS-i lu-nar dust simulant developed by the Institute of Geochemistry of C A S contains 7 5 % glass and a little nanophase Fe0 , and has a median particle size about 500 ？600 n m . T h e CLDS-i lunar simulant par-ticles also have complicated shapes and sharp edges similar to those of the lunar dust which make the CLDS-i applicable to many fields such as the scientific research, the treatment technology and toxi-cological study of the lunar dust.
