Rubber airbag technology for inflatable boats
According to CB/T 3795-1996, the Ship Launching Inflatable Airbag should meet the following requirements.
1. Dimensional tolerance
Deviation between diameter and effective length: ±2%
Total length deviation: ±4%
2. Elastic deformation: Under 1.2 times of working pressure, the diameter deformation is less than 5%.
3. Safety factor:> 4.5
4. Air tightness: pressure drop <5% after 1 hour of inflation
5. Product surface quality: streamlined, no cracks, no bubbles, no double skin, no impurities, no obvious defects such as obvious dirt.
6. Explosion-proof design at the end.
Marine Airbag For Ship Launching Introduction
The Ship Launching Inflatable Airbag is made of rubber and multi-layer impregnated tire fabric.
Marine rubber airbags are widely used for launching ships, lifting and carrying heavy objects, and rescuing stranded ships.
The use groups of marine rubber airbags are concentrated in shipyards, shipowners and marine supplies companies.

Used marine airbags technical details
Whole Intertwine Technology
"Henger" Ship Launching Inflatable Airbag overall frame structure uses cross whole intertwine technology, the overall structure is more reasonable, texture clear, no juncture, high loads, more safety than lap technology (roller), more than 20% bearing capacity.
Framework
Henger" airbag structure are consist of the outer rubber + synthetic cord reinforced rubber layers.
Its shape characteristics: central body cylindrical + tapered on both ends.
Cord layers: 4,5,6,7,8,9,10,11,12 layers.

Advantages of airbags
High capacity
The requirements for inflatable rubber airbags were regulated in CB/T 3795-1996 issued by China State Shipbuilding Corporation.
Hunger uses a new rubber formula and high-strength reinforced synthetic tire cord layer, which doubles the load-bearing capacity of the airbag, which is higher than the CB/T 3795-1996 standard.
The synthetic tire cord layer of Henger's marine airbag adopts impregnated Nylon-6 1400dtex / 3-V2 tire cord.
The strength and durability of the Airbag have been increased by 20%.
