INTRODUCTIonMarine Rubber Airbag is china independent intellectual property rights of innovative products, the products are mainly applied to shiplaunching and landing, weight liftingand moving, installation of underwater buoyancy aidto salvage sunken vesselsetc.Airbags launching technology was developed based on traditional slipway launching mode, it overcomes the restrictions of traditional slipway launching mode. Our marine rubber airbags are less limited by space, no large mechanical equipment, can shorten the working periodand save the unnecessary cost.Through years of development practice, our products arebecome more safety, effectiveandgreen environmental protectionand they can launching a ship up to 100,000 DWT. Nowadays, Marinerubber airbagsare widely used in the world. 2. AIRBAG STRUCTURE & MATERIAL REQUIREMENTS2.1 Airbag Structure "XINCHENG" Marine Rubber Airbags' structure isconsistsof the outer rubber layer synthetic cord reinforced rubber layersand inner rubber layer. Its shape characteristics: central body cylindrical + tapered on both ends.Cord layers: 4,5,6,7,8,9,10, layers Accessories: Pressure gage, Inlet valve, Pipe fitting and seal end ring. 2.2 Material Choose the best quality of imported natural rubber, such as smoked sheet rubber and 3L natural rubber from Thailand and Malaysia, which has good elasticity, ageing resistance, and will not take off layer. Meanwhile, During the process of produce rubber, we using efficient stabilizer to make rubber more environmentally friendly and no cracks.

The airbags should be maintained in a dry,ventilated room and be protected from light. The airbags should be stored in a relaxed condition free from tension,compression or other deformation. The airbags should be kept away from any heat source. The airbags should be protected from acids, alkalis, oils or organic solvents.
