Technical Depth and Problem-Solving Capabilities of Integral Molded Inflatable Seals in Extreme/Special Scenarios
Scenario 1: Inflatable seal of Deep-Sea Exploration Equipment (Pressure ≥110MPa, Temperature 4℃)
1. Extreme Challenges
Dual Effects of Pressure and Corrosion: Deep-sea environmental pressure increases exponentially with depth (1MPa increase per 10 meters), while the salinity of seawater (3.5%) accelerates corrosion of metal components. Traditional seals are prone to leakage due to material creep or stress relaxation.
Dynamic Sealing Requirements: Exploration equipment must withstand sudden pressure changes during ascent and descent (e.g., rapid ascent from a depth of 1000 meters to the surface). Seals must possess elastic compensation capabilities to prevent tearing.
2. Technological Breakthroughs
Material Innovation: Utilizing hydrogenated nitrile butadiene rubber (HNBR) and carbon fiber composite materials, nanoscale carbon fiber dispersion technology enhances…
