Shunhang Wear Resistant Natural Rubber Ship Launching Airbag
History if Ship Launching Airbags
6000 years ago, our ancestor begin to use log-rolling method to lift and move weights, which is still widely used in daily production and actual life nowadays. Marine rubber airbag is designed with soft rubber to lift and carry weights, based on log-rolling method.
Ship Launching airbag is an innovative product of Chinese own
proprietary intellectual property rights. It has wide application
like ship launching & upgrading, caisson lifting & moving,
heavy weights lifting, underwater-engineering buoyancy aid. The
marine rubber airbag is not limited to space and heavy machinery,
which could efficiently shorten the construction period and save
lots of funds.
Feature of Shunhang Products:
1. Big carrying capacity
The carrying capacity of the inflating marine rubber airbag is an
important indicator of its quality. The CB/T 37951996, The Airbag
For The Ships Up To Slipway And Launching, specifies its working
pressure and the load-bearing capacities per meter under various
compression ratio. Our new generation of airbags are made of novel
rubber compounding and high-tension fortifying fiber. Their
carrying capacities have been over one times stronger than the
standard requirements. That means that less airbags are needed for
the ships up to the slipway and launching if with Shun hang marine
rubber airbags meanwhile the safe reliability is also guaranteed.
2. High capacity against compression and twisting
When the airbag moves under the ship bottom, it will be compressed
between the ship bottom and the ground. As the rolling velocities
are not the same among them, they would be torsional deformed. This
composite deformation created by both the compression and twisting
is described as compressed and twisted movement. When such
compression and twisting happens on the air bag, its partial wall
would buckle. Then the wall in structure of the multi-layer
fortifying fibers would very easily laminate and tear out,
resulting the breaking of the fortifying fiber and consequentially
the bursting of the entire airbag.
3.New design of anti-bursting construction at the end
For our new generation of airbags, both the rubber compounding and
making process are improved so that their structural tearing
strengths are improved and so for their capacity for twisting and
compression resistance. The deflating possibility would increase at
the joint of the end ironwork and the rubber as the working
pressure rises.Once it leaks at the end after repeated operation,
the end would be more likely to burst out under the high pressure
and injure the people.Such accidents due to poor air bag quality
have happened many times in the ship launching. We should keep
alert on it. To meet the requirement on the air tightness under
high internal pressure, the new anti-blasting construction is
designed with the end to enhance the binding strength and air
tightness at the joint of the bag body and end ironwork. This
design could meet the increased working pressure and has been free
of the leakage so far in use and proved safe.
