Advantages of Gu Te rubber airbag

1.Big carrying capacity

The carrying capacity of the inflating marine rubber airbag is an important indictor 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 Gu Te 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 torsionally 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.

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.

3.New design of anti-bursting construction at the end

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.

4.Optimized structural layout

The principle for optimizing the structural layout is to determine the size and orientation of the major stress in the working process, and then adjust the angle of the cord yarn at each layer to equalize the stressing onto each later more or less in order to give a full play to the efficiency of the fortifying fiber.

For this purpose, we have established the strength model for the inflating rubber airbag and also tested the compressive property. We also studied the variation law of the size and orientation of the major stress on the bag wall and found out the best cord yarn layout. The new design has been proved very successful through bursting test and in-service use. .

5.Durable aging resistance and anti-wear characteristic

The marine airbag works in very harsh environment where it is exposed to the sunlight, seawater, grits and pollutants. So the surface of the airbag must be wear resistant, sea water and chemical resistant and anti-aging. With its substrate made of natural rubber and auxiliary materials, Gu Te marine rubber airbag with the high carrying capacity is proved to be of durable aging resistance and wearing quality.

6.Higher flexibility and damping capacity

Gu Te inflating marine rubber airbag is made by the special overall windup process and low-temperature long curing. Its wall thickness is even without the secondary seam coming from the lap joint. So Gu Te inflating rubber airbag can be made more thin, flexible and elastic under the same strength. When it rolls under the ship bottom, the contact pressure with the bottom would be less and even and it also has higher damping capacity. When the ground is sloped or rugged, such soft elastic property is in favor of eliminating the structural stress and lowering risk of ship going into the water.
