Integral molded inflatable seals for research vessels

Technical Depth and Problem-Solving Capabilities of Integral molded inflatable seal in Extreme/Special Scenarios   Scenario 3: Low-Temperature Sealing for Polar Research Vessels (-50℃ to Room Temperature Cycling)   1. Extreme Challenges   Low-Temperature Embrittlement and Thermal Expansion/Contraction: Polar environments reach temperatures as low as -50℃, making traditional rubber seals prone to embrittlement and breakage. Furthermore, thermal expansion and contraction during temperature cycling (e.g., from -50℃ to 20℃) can cause the sealing surface to loosen.   Prevention of Ice Shavings Intrusion: Ice shavings formed from splashed seawater during ship navigation may become lodged in the inflatable seal gaps, scratching the sealing surface.   2. Technological Breakthroughs   Material Innovation: A blend of silicone rubber (VMQ) and fluorosilicone rubber (FVMQ) is used. By controlling the crosslinking density of the molecular chains, the glass transition temperature (Tg) is lowered to…
