8 Layers Inflatable Marine Rubber Airbag With Many Different Size
Floating Rubber Airbag for ship launching/landing/slipping. Airbags
for ship are also known as air balloon,inflatable bags,roller
bags,air lifting bags,salvage bags.Standard floating rubber airbag
size range is 0.8m to 2.0m diameter,with length up to 18.0m
effective length and even more.
Floating Rubber Airbag now are used for ship launching ,loading and
floating.They are widely used in cargo boat/ship/vessel launching
and landing,lifting and moving sunken ships and salvaging strandde
boats. Floating Rubber Airbag have the benefit of not only saving
labor and time,but investment costs.Additionally they are
flexible,prortable and dependable.
1) Outer Rubber Layer
The outer rubber layer that covers the outside of marine airbag to
protect under layers from abrasion and other external forces. This
compound has sufficient tensile and tearing strength to withstand
any condition and hard usage.
2) Inner Rubber Layer
The inner rubber layer seals pressurized air inside marine airbags.
3) Synthetic-Tire-Cord Layer as Reinforcement
The reinforcement cord layers, which are made of
synthetic-tire-cord commonly used in tires, are arranged at ideal
angles to hold the internal pressure and distribute stress evenly.
So they can provide strong efficient reinforcement.
echnical Strengths:
1. Higher content Natural Rubber materials, 56%. Higher content
natural rubber prove to be superior quality.
2. Gas Tightness. We design to secure the Pressure Decrease is not
exceeding 5% around approximately 72 hours
3. Configuration of Airbag Layers. Layers should mean corresponding
synthetic tyre cord layers and additional rubber layers combination
to secure longer lifespan.
4. Breaking force of Synthetic-Tyre-Cord. Every strand is over
31kgs breaking force to reinforce the tensile strength.
