Abstract

The invention discloses a liquid metal material for noise reduction in nuclear reactor environment and a processing technology thereof. The liquid metal material comprises, by weight, 0.1%-0.2% of Se,5.0%-15.0% of Sb, 20.0%-25.0% of In, 0.5%-1.0% of V, 1.5%-2.0% of Ag, 10.0%-15.0% of Pb, 5.0%-10.0% of Cd, and the balance Sn. The liquid metal type vibration reduction alloy material can be coated in a gap for vibration reduction through a simple heat source. The liquid metal material is characterized in that technology equipment is simple, the operation technology is easy to grasp, the construction cost is low, and the vibration reduction effect is remarkable.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a lead alloy. Background technique [0002] The use and research and development of nuclear energy is an important symbol to measure a country's national defense strength and national economic level. Nuclear power has become a clean, efficient and reliable energy source in the 21st century when energy is very scarce. Therefore, the research and industrialization of nuclear energy is an area of ​​widespread concern in various countries. During the normal production process of the reactor, a lot of mechanical facilities are needed to cooperate. Therefore, in the modern nuclear industry, the pollution and hazards caused by mechanical vibration are becoming more and more serious. [0003] The catastrophic consequences of vibration and noise on equipment and human health are manifold. For instruments and equipment, vibration can significantly reduce the accuracy of the instrument a...
