The Introduction Of Marine Airbag
The first flexible ship launching technology is China's marine inflatable rubber airbag. It mainly relies on cylindrical rolling to place the marine airbag on the bottom of the ship and slowly drive it into the water to avoid damage to the hull structure and its surface coating. It dramatically reduces the cost of launching ships, has no limitations, and improves work efficiency. Thus, it has been widely promoted.
Marine airbags are a new product that has been independently developed in my country. They have been widely used in ship launching and launching operations, ship stranding to aid floatation, and heavy object handling and displacement. After more than 20 years of development and practice, most shipowners have accepted marine airbags. These advantages include fewer site restrictions during use, no need for large machinery and equipment, safety and efficiency, flexible operation, and low capital investment.
And recognized.
Luhang's Airbag
Qingdao Luhang Airbag Fender Co., Ltd. has been committed to the research and development of high-strength marine airbags since its early days. New mechanical models and damage mechanisms, new rubber formulas, new vulcanization processes, and new manufacturing methods have been developed specifically, and breakthroughs have been made in areas such as airbag structural layout.
Our company's marine airbags adopt the latest overall winding technology. Our company uses advanced three-dimensional animation simulation technology to adjust the cord layout for a series of undesirable factors caused by difficult situations, such as the direction and size of the ship's force on the airbag when the airbag rolls on the bottom of the boat, the squeezing of the airbag when it rolls, and so on. A reasonable and effective winding method is designed to improve the safety and reliability of the airbag launching into the water.
The Size
1. The size of diameter D is divided into 0.6m, 0.8m, 1.0m, 1.2m, 1.5m, 1.8m, 2.0m, 2.5m, 3.0m
2. Effective length L is from 3 meters to 30 meters
3. The number of cord fabric layers is divided into three curtains and four types of glue: SS-3, four curtains, and five types of glue; SS-4, five curtains and six types of glue; SS-5, and six curtains and seven types of glue, SS-6.
4. Special sizes can be processed according to customer requirements.
Raw material selection
1 rubber. To be suitable for airbags to work in harsh environments, our company selects high-quality natural rubber as the primary raw material, adds various auxiliary materials, and has a reasonable formula with durable anti-aging and wear-resistant properties.
2 Nylon "6" dipped cord fabric. The bladder skeleton material cord fabric density is (90±5) cords/10cm wide, and the breaking strength is not less than 205.8N/cord. The maximum breaking strength can reach 313.6N/root.
Advantages of Luhang's airbag
01
Our company uses high-quality natural rubber as raw material, adding styrene-butadiene and other auxiliary materials. The rubber content can reach more than 56%, and the rubber tensile strength is more significant than 20Mpa;
02
The skeleton is made of high-quality nylon dipped cord fabric with three strands per piece according to customer needs. Its single strand breaking strength is 313.6N, thus significantly improving the performance and service life of the product;
03
The end of the airbag adopts a new anti-explosion design structure, which enhances the bonding strength and sealing performance of the bag and the end iron parts. No deflation has occurred so far in use, eliminating potential safety hazards.

Customer Case
After many comparisons, the customer finally chose Qingdao Luhang Airbag Fender Co., Ltd., which produces 12 rubber airbags with a diameter of 1.8 meters, an adequate length of 12 meters, and a total of 7 layers. Production and shipment went smoothly, and customers once again recognized the quality.
Pressure And Airtightness Testing
The test was performed using a full-sized airbag with a diameter of 1.8 meters, an adequate length of 12 meters, and seven layers. The customer's required working measure is 0.25Mpa.
Without carrying any load, fill the airbag with an internal pressure of 0.25Mpa. The internal pressure was recorded, and the pressure loss was less than 5% after one hour.
All our products are strictly by ISO standards. Quality is our advantage.
