Air Tightness Inflatable Marine Rubber Airbag Used For Boats And
Ships
Advantages of Florescence inflatable rubber airbag
New design of anti-bursting construction at the end
For our new generation of airbags. Both the rubber compounding and
making process are improved so that their structural tearing
strengths are improved and so for their capacity for twisting and
compression resistance. The deflating possibility would increase at
the joint of the end ironwork and the rubber as the working
pressure rises .Once it leaks at the end after repeated operation,
the end would be more likely to burst out under the high pressure
and injure the people. Such accidents due to poor air bag quality
have happened many times in the ship launching .We should keep
alert on it . To meet the requirement on the air tightness under
high internal pressure, the new anti-blasting construction is
designed with the end to enhance the binding strength and air
tightness at the joint of the bag body and end ironwork. . This
design could meet the increased working pressure and has been free
of the leakage so far in use and proved safe .
Optimized structural layout
The principle for optimizing the structural layout is to determine
the size and orientation of the major stress in the working
process, and then adjust the angle of the cord yarn at each layer
to equalize the stressing onto each later more or less in order to
give a full play to the efficiency of the fortifying fiber. For
this purpose .we have established the strength model for the
inflating rubber airbag and also tested the compressive property.
We also studied the variation law of the size and orientation of
the major stress on the bag wall and found out the best cord yarn
layout. The new design has been proved very successful through
bursting test and in-service use.
The structure of Florescence rubber airbag:
It consists of a bag body and an iron-end component. The bag body
is manufactured by vulcanizing the preliminary shaped airbag made
of base rubber and reinforced fiber material. The material of the
iron- end component is metal, and it is connected to the bag body
firmly.

Storage of the air bag
* If the air bag will not used for quite a long time, it shall be
washed and dried, filled with French chalk inside and coated with
French chalk outside as well as put in dry, shady and ventilated
place in the room.
* Place storing the air bag shall be far away from the heat source.
*The air bag can’t contact with acid, alkali, grease and organic
solvents.
* The air bag should be stretched flat when not used. it’s not
allowed to pole up and stack heavy object on the air bag.
