Product Introduction:

 

What were the first uses of airbags in the launching of ships?

 

The history of rubber marine airbag ship launching dates back to 1981. Xiao Qinghe ship repair and building shipyard, located in Jinan city of Shangdong Province, launched a 60 DWT tank barge with airbag suspension on January 20, 1981. Seven airbags were deployed in that project. One was 2 meters in diameter and 6 meters long and used for elevating. The remaining six airbags were 0.8 meters x 6 meters long and acted as the rollers. The first intention of that trial launch was to develop a prompt, less landform limited ship launching method for warfare purposes.

 

How has the technology advanced since then?

 

Over the past twenty years, the airbag ship launching system has made advancements in not only the airbag, but also the ship launching/landing technology. The first generation airbags used a rubber dipped canvas as a reinforcement layer to form the air chamber trunk. Two cone-shaped molds were then used to make the ends and everything was stuck together.

With today’s airbags, the whole-enlacing-technology used for manufacturing is done together. Rubber dipped synthetic-tyre-cords are used as the reinforcement layers with the trunk and two cone-shaped ends made at the same time. Everything is then-laced together, so the airbag doesn’t have any joints. Due to the development of rubber chemistry, the performance of the rubber employed in the latest airbags is highly enhanced and about 15 times that of the first generation bag with the same specifications.

The launching and landing technology has also developed. In the beginning, only small and flat bottom ships located on a fabricated slope could be launched with airbags. Now this technology is more flexible and less limited by the ship and landform. Now any type of ship with a DWT below 55,000 and in a place with enough launching space can be launched using airbags. The launching slope even can be sloped upward. It has really developed into a cutting edge technology for launching ships, and especially useful for some marine emergencies.

 

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.

Storage of the Airbags


1. If the airbags won’t be used for quite a long time, it shall be washed and dried, filled with talcum powder inside and coated with talcum powder outside, place it in dry, shady and ventilated place in the warehouse.
 

2. Place string the airbags should be far away from the heat source.
 

3. The temperature of the warehouse should be kept no more than 30℃.
 

4. Keep the airbags away from acid, alkali, grease and organic solvent.
 

5. The airbags should be stretched flat when not used. It is not allowed to pile up and stack heavy object on the airbag.
