Study on the compressive performance of reactive gel catalyst in underwater robot shell
Introduction
With the development and exploration of marine resources, underwater robots (ROVs) play an increasingly important role in the fields of deep-sea exploration, submarine resource development, marine environmental monitoring, etc. As one of its core components, the underwater robot shell not only needs to have good sealing and corrosion resistance, but also needs to maintain stable mechanical properties in deep-sea high-pressure environments. As a new material, reactive gel catalysts have been gradually applied to the manufacturing of underwater robot shells due to their unique chemical and physical properties. This article will discuss in detail the compressive performance of reactive gel catalysts in the underwater robot shell, and analyze them in combination with actual product parameters.
1. Characteristics of reactive gel catalyst
1.1 Definition of reactive gel catalyst
Reactive gel catalyst is a gel-like material formed by chemical reactions, with high elasticity, high strength and self-healing ability. Its unique molecular structure allows it to maintain stable physical properties under high pressure environments.
1.2 Main features
- High elasticity: Can quickly return to its original state when subjected to external forces.
- Self-repair ability: After being damaged, it can be automatically repaired through chemical reactions.
- Corrosion resistance: It has high tolerance to salts and microorganisms in seawater.
- Lightweight: Low density, which can reduce the overall weight of the underwater robot.
1.3 Application Areas
Reactive gel catalysts are widely used in aerospace, automobile manufacturing, medical devices and other fields. In recent years, with the increase in the demand for deep-sea exploration, its application in marine engineering has also gradually increased.
2. Design requirements for underwater robot shells
2.1 Characteristics of deep-sea environment
- High Pressure: Every 10 meters of water depth increases, the pressure increases by about 1 atmosphere.
- Low Temperature: The deep sea temperature is usually between 0-4℃.
