Product Description
1. INTRODUCTION Marine Rubber Airbag is china independent intellectual property rights of innovative products, the products are mainly applied to ship launching and landing, weight lifting and moving, installation of underwater buoyancy aid to salvage sunken vessels etc. 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 period and save the unnecessary cost. Through years of development practice, our products are become more safety, effective and green environmental protection and they can launching a ship up to 100,000 DWT. Nowadays, Marine rubber airbags are widely used in the world. 2. AIRBAG STRUCTURE & MATERIAL REQUIREMENTS2.1 Airbag Structure "XINCHENG" Marine Rubber Airbags' structure is consists of the outer rubber layer synthetic cord reinforced rubber layers and 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.

Storage: - When the airbags are not to be used for a long period of time, they should be drained,cleaned,dried,filled with talc powder, and the exterior surfaces should be coated with talc powder. 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.
