Marine rubber balloon layout
Rubber Airbags, basic body consists of rubber layers, synthetic-cord-reinforced rubber layers, are kind of a cylindrical airbags with hemispherical heads at the both ends. All of these are vulcanized together, and then compress air inside to enable in to roll.
Culvert Making Rubber Balloon Materials
An airbag is to be constructed of an outer rubber layer, one or more synthetic-tyre-cord layers, and an inner rubber layer. The arrangement of synthetic-tyre-cord reinforcement layers is shown in the picture below, all materials shall be vulcanized firmly.
Prior to the airbag production, the outer and inner rubber layers shall be tested to meet criteria in the following table in accordance with the test methods given in the international standard list in the table.
While only one satisfactory sample per batch is required for test numbers 1 through 3, all others must be tested for test numbers 4 through 9 annually. If the first sample fails, two additional sample should be tested. If the additional samples pass the test requirements, the materials will be deemed to have passed the test. Otherwise, the materials will be deemed to have failed the test and another batch of materials shall be selected.
The appearance of an airbag shall be smooth, glossy and without blemish such as crack, blister, decontamination, pits or impurities.
Rubber airbag Size information:
Diameter from 0.5m to 2.8m
Length from 5m to 24m
Marine airbag Parts：
Florescence Rubber Balloon Repair:
Structure and equipment as following pic1
Operation steps see pic 2: heat airbags and repair rubber pad together by heater steel plate.
when the temperature reach about 135℃, you can stop the heater and wait, till the temperature
cool down to 80℃(cooling need about 40 minutes).
The heater, like picture 1, will put on the airbag, but need a cotton cloth between heater and airbag to protect. Then above the heater is a wood and then jack. After all things are put in order, you can switch on electricity and heat the airbag.
