Heavy - Duty Marine Rubber Airbag
Introduction
Our Heavy - Duty Marine Rubber Airbag is a top - of - the - line product designed to meet the most demanding requirements in the marine industry. Engineered with precision and built to last, these airbags are essential tools for a variety of marine applications, providing reliable support and protection.
Development
In 1981, Qiao Changlin, the deputy director of the Xiaoqing River Shipping Bureau of the Shandong Provincial Department of Communications, invented the first - generation lap - joint rubber airbag. Its skeleton material was rubber - coated canvas. On January 20, 1981, the first ship - launching test using this airbag was carried out at the Xiaoqing River Shipyard and achieved success. In the early 1990s, technological innovations were made. Nylon cord fabric replaced canvas as the new skeleton material, and a new integral winding manufacturing process emerged.
Key Features
Robust Construction
Crafted from high - quality, thick - walled rubber, our heavy - duty airbags are built to withstand extreme pressures and harsh marine environments. The rubber used is a special blend that offers exceptional strength, tear resistance, and abrasion resistance. This ensures that the airbag can endure the rigors of continuous use, whether it's in rough seas or during intense ship - related operations.
High Load - Bearing Capacity
One of the most remarkable features of our Heavy - Duty Marine Rubber Airbag is its extraordinary load - bearing capacity. These airbags are designed to support substantial weights, making them ideal for applications such as ship launching, ship lifting, and underwater salvage operations. They can safely handle the weight of large vessels, providing a stable and secure means of support during critical marine tasks.
Excellent Sealing Performance
The airbags are equipped with advanced sealing mechanisms that prevent air leakage, even under high - pressure conditions. This ensures consistent performance and reliability during use. The tight seal not only maintains the necessary pressure within the airbag but also extends its lifespan by protecting the internal structure from moisture and other contaminants.
Temperature Resistance
Marine environments can experience a wide range of temperatures, from extreme heat in tropical regions to freezing cold in polar waters. Our Heavy - Duty Marine Rubber Airbag is designed to perform optimally in these varying temperature conditions. The rubber material used has excellent temperature resistance properties, allowing the airbag to remain flexible and functional in both hot and cold climates.
Application
Ship Launching and Landing: This is the most common application. From small flat - bottomed boats to large - scale ocean - going vessels, airbags are widely used. For example, the Chinese research mother ship “Zhang Qian” was launched using marine airbags in Zhejiang Wenling in March 2016.
Heavy - Object Handling: They are extensively used in port construction, such as for lifting, moving, and launching caissons.
Salvage and Flotation Assistance: With their large buoyancy and high load - bearing capacity, they are effective in rescuing stranded ships.
Maintenance
Storage: When not in use for an extended period, airbags should be cleaned, dried, coated with talcum powder both inside and outside, and stored in a dry, cool, and well - ventilated indoor area. They should be laid flat and not stacked, and no heavy objects should be placed on them.
Repair: In case of damage, specific procedures need to be followed. For example, for different types of cracks (longitudinal, transverse) and punctures, steps such as demarcating the repair area, sanding, cleaning, and patching with appropriate materials should be carried out.
