High Strength Safety Airbags for Seawater Launch

Qingdao SunKai factory's High Strength Safety Airbags for Seawater Launch are optimized for the characteristics of seawater environment—high salt, high humidity, strong corrosion—and the requirements of ship launching—large load, instantaneous impact, and complex operation conditions. It adopts high-strength composite materials and advanced integral molding technology, fully complies with industry standards and international standards.

It is widely applicable to the launching of cargo ships, passenger ships, offshore work ships, etc., and can also be used for temporary lifting, shifting and maintenance of ships in seawater environments, providing reliable high-strength seawater launch solutions for global marine operation institutions.

Key Performance Features

- Ultra-High Strength Reinforcement Structure: Adopt a four-layer composite reinforcement design, the inner layer is a high-density airtight rubber layer, the middle two layers are reinforced with high-strength aramid cord (tensile strength up to 3000N/tex) cross winding, and the outer layer is a seawater-resistant protective rubber layer. The overall strength is 4 times that of ordinary marine airbags, the safety factor is up to 5.2, which can stably bear the weight of ships up to 100000DWT, and resist the instantaneous impact force during launching without deformation, tearing or air leakage.

- Professional Seawater Corrosion Resistance: The outer layer adopts imported seawater-resistant neoprene rubber, adding special anti-corrosion, anti-salt spray and anti-microbial additives, combined with high-temperature vulcanization technology, which can effectively resist the erosion of seawater, salt spray and marine microorganisms. After 3000 hours of seawater immersion test, the product performance remains more than 90% of the original, no swelling, no cracking, no performance degradation, suitable for long-term use in seawater environments.

- Extreme Sea Condition Adaptability: Optimized for complex sea conditions such as waves, tides and strong winds in seawater launching scenarios, the product is designed with a streamlined structure to reduce the impact of waves on the airbag during launching; the air chamber is divided into independent compartments, even if one compartment is damaged, it will not affect the overall use, ensuring the safety of launching operations in extreme sea conditions. The applicable temperature range is -30℃ to 70℃, which can cope with extreme weather such as marine low temperature, high temperature and heavy rain.

- Stable Load-Bearing & Anti-Impact: Adopt three-dimensional simulation stress optimization technology, make the stress distribution of the airbag uniform, avoid local stress concentration, and ensure stable load-bearing during launching. The airbag surface is designed with a wear-resistant and anti-slip texture, which can enhance the friction between the airbag and the hull, avoid slipping during launching, and effectively protect the hull from scratches. At the same time, it has excellent impact absorption performance, which can reduce the instantaneous impact force between the hull and the airbag, ensuring smooth launching.

- Efficient Operation & Easy Maintenance: Equipped with a high-pressure quick inflation and deflation valve, which can complete inflation and deflation in a short time, improving launching efficiency; the High Strength Safety Airbags for Seawater Launch are designed with a modular structure, which is easy to carry, install and disassemble, and can be quickly arranged according to the ship tonnage and launching site. The surface protective layer is smooth and easy to clean, and regular simple maintenance (such as cleaning, drying and anti-corrosion treatment) can further extend the service life, reducing maintenance costs for users.
