Floating ship airbag for ship launching have the best designed structure which consists of five different functional membranes in rubber layers.
1) Outer Rubber Layer
The outer rubber layer that covers the outside of ship airbag to protect under layers from abrasion and other external forces. This compound has sufficient tensile and tearing strength to withstand any condition and hard usage.
2) Inner Rubber Layer
The inner rubber layer seals pressurized air inside ship airbags.
3) Synthetic-Tire-Cord Layer as Reinforcement
The reinforcement cord layers, which are made of synthetic-tire-cord commonly used in tires, are arranged at ideal angles to hold the internal pressure and distribute stress evenly. So they can provide strong efficient reinforcement.
The bearing capacity of floating ship airbags was calculated based on the working pressure, contact area. Herein, working pressure was got upon the burst pressure and safety working factor.
Because of the flexibility of floating ship airbag the contact area will be affected by some terms which include the carried ship condition, the different position from gravity center during the process of ship launching and pulling. So the bearing capacity of airbags will vary as well as the contact area.
The approximate bearing capacity can be calculated as follows:
F=PS
S=π x (D1-D2)/2
Mark:
F: Bearing capacity
P: Inner pressure
S: Contact area
D1: Diameter of airbags when free of loat
D2: Working height of airbags when loaded
1 High bearing capacity
Floating ship airbag's main technical requirement is regulated in CB/T 3795--1996 published by China State Shipbuilding Corporation.
Florescence adopts new rubber formula and high-strength enhanced synthetic-tyre-cord layer, which improves the airbag's bearing capacity two times more than CB/T 3795--1996 standard
2 High kneading-resistance capability
When the airbag is rolling under the ship bottom, it will suffer a "kneading force" from ship bottom and ground because of not uniform rolling speed, which could case problems like delamination, layer buckling, etc.
Florescence improved the manufacturing technique and raw material formula to strengthen kneading-resistance capability of the airbag and avoid worse accident .
3 New anti-explosion design of end part
The possibility of air leakage in the joint area of metal part and rubber part is also increasing as working pressure of airbag is added. After using for times under high working pressure, the airbag would burst and metal part would hurt workers.
Florescence invented new anti-explosion design of the airbag end part, increasing the bonding strength and air tightness between rubber body part and end metal part. Florescence airbag is working very well under higher working pressure without potential safety hazard.
4 Optimizing structure configuration
Florescence built a strength and Intensity Model to test compression performance, stress intensity and direction. After testing for many times, we got the stress changeing regularity and optimized structure configuration design. The new optimized airbag successfully passed blasting experiment and achieved good performance in practical use.
5 Good Abrasion-resistance performance and high ageing resistance
The airbag is working under bad and poor condition, suffering from long time sunlight exposure, seawater corrosion, impurities pollution, etc. The surface of airbag must be equipped with high capability of abrasion resistance, ageing resistance, corrosion resistance.
Florescence airbag is made of natural rubber with special ingredients and unique manufacturing method. The finished airbag could working very well under above mentioned bad and poor working condition.
6 Higher flexibility and shock absorption capability
Florescence airbag is manufactured with unique integral twining technique. The airbag wall thickness is uniform with secondary seam in overlap joint. When rolling in slope and uneven ship path, the flexible airbag is helpful to reduce structure stress and ship launching risk.
