Marine Rubber Airbag Manufcturer | Ship Launching Airbag

해양용 고무 에어백 소개

A marine rubber airbag is based on the log rolling method, using soft rubber for lifting and bearing. It is an innovative product with independent intellectual property rights in China. It is widely used in the fields of heavy lifting, ship launching and upgrading, caisson lifting, and underwater engineering buoyancy aid. Marine rubber airbags are not restricted by space and heavy machinery, which can effectively shorten the construction period and save much money.

1. Ship Launching and Upgrading

After more than 20 years of development in China, marine rubber airbags have proved to be the most reliable and stable technology for ship launching and upgrading. It is suitable for tonnage flatbed to 10,000 tonnes giant ships. Meanwhile, foreign shipyards, dockyards, and port construction companies also widely recognized marine rubber airbags. The ship launching and upgrading technology of marine rubber airbags has also been vigorously promoted in America, Europe, Southeast Asia, and other markets.

Jerryborg Rubber Airbags Advantages

1. High Load Carrying Capacity

제리보그 마린에서 제조하는 선박용 고무 에어백의 주요 기술 요구 사항은 ISO 14409 "선박 및 해양 기술 - 선박 발사 에어백"을 준수합니다.

Jerryborg uses a new rubber formulation and a high-strength reinforced synthetic tire cord layer, making the airbag’s load-carrying capacity twice as high as the ISO 14409-2011 standard.

The synthetic-tyre-cord layer of Jerryborg marine rubber airbag adopts 1480D텍스/2 친론 타이어 코드.

The strength & durability of our rubber airbag improves 40%, compared to 폴리에스테르 타이어 코드.

1480dtex/3 타이어 코드가 특수 설계된 에어백에 언젠가 적용됩니다.

2. High Kneading Resistance

Due to the uneven rolling speed, when the marine airbag rolls under the ship, it is subject to the ‘kneading force’ of the ship’s bottom and the ground, which is prone to delamination, layer buckling, and other problems.

Jerryborg has improved the production process and raw material formula to enhance the kneading resistance of airbags to avoid more serious accidents.

Each layers of our rubber airbags are painting with specially formulated mucilage to dissolve impurities and dust.

The specially formulated mucilage also increases the adhesiveness of each layer to guarantee air tightness.

3. New End Metal Parts Anti-Explosion Design

As the working pressure of the airbag increases, the possibility of air leakage in the area where the metal part meets the end rubber body increases. After repeated use at high operating pressures, the airbag will burst at the end metal part, causing injury to nearby workers or facilities.

제리보그 발명 a third-generation anti-explosion design for the airbag ends, which improves the bonding strength and airtightness of the rubber body part to the metal part of the ends. Jerryborg Marine’s airbags work well at higher operating pressures without potential safety hazards.

4. 구조 구성 최적화

Jerryborg established a strength and intensity model to test the compression performance, stress intensity, and direction. After several tests, the change rule of stress was obtained, and the structural configuration design was optimized. The optimized airbag successfully passed the bursting test and achieved good practical use performance.

그리고 hydraulic burst test is a full-scale extreme test of marine rubber airbag performance, materials, structural design, and manufacturing process.

Jerryborg marine airbag test results exceed industry standards.

5. Good Abrasion Resistance & High Aging Resistance Performance

Airbags work in poor conditions, such as long sun exposure, seawater corrosion, and impurity pollution. The surface of the airbag must be highly resistant to wear, aging, and corrosion.

Jerryborg airbags are made from natural rubber, have a special composition, and use unique manufacturing methods. The finished airbags work well under the harsh operating conditions described above.

6. Higher Flexibility and Shock Absorbing Capacity

Jerryborg airbags are manufactured using a unique monolithic winding technology. The airbags have a uniform wall thickness and secondary seams at overlapping seams. The flexible airbag helps to reduce structural stresses and the risk of ship launching when the ship rolls on slopes and uneven channels.
