How to repair the airbag?
(11) Brush the gasoline and wait until the surface dry.
(12) Put one layer Nylon rubber obliquely . The Nylon direction should be the same as Nylon direction on the airbag wall . The scope of overlapped should be 1cm larger than last layer and round the four corners. (Picture 7c for your reference).
(13) Brush the gasoline again and wait until the surface dry.
(14) Put one layer Nylon rubber obliquely with symmetric direction of last layer with the same angle. The scope of overlapped should be 1cm larger than last layer and round the four corners. (Picture 7d for your reference). For 4 layers or less than 4 layers airbag with longitudinal cracks, can stop put more Nylon rubber layer and turn to the step 17. For 4 layers airbag with transverse crack and nail eye damage , go on step 15 and 16
(15) Brush the gasoline again and wait until the surface dry.
(16) Put one layer Nylon rubber perpendicularly to longitudinal direction. The scope of overlapped should be 1cm larger than last layer and round the four corners. For airbag less than 5 layers, can stop put more Nylon rubber layer and turn to the step 17. For airbag with 5 layers , repeat the step 9, 10. The scope of overlapped should be 1cm larger than last layer and round the four corners. Then turn to the step 17.
For airbag more than 5 layers, repeat step 11 to 14. Then turn to the step 17.
(17) Brush the gasoline again and wait until the surface dry.
(18) Put one layer pure rubber on the surface.
(19) Compaction the Nylon rubber layers , remove the air from the Nylon rubberlayer.
3. Heating
The shipyard can make a working platform as shown on the picture and prepare Jack , U-steel , steel heating plate, cotton cushion , sandbag,steel plate. The heating steel plate thickness 25mm, Length 0.5m, Width 0.4m, all the four corners and edge should be smooth.
Put the airbag in the center and heat the steel plate ,using the thermometer to check the temperature of the steel plate. When the temperature rise to 150 ±5 degree centigrade, can be put on the cotton cushion and the damaged airbag area , tight the Jack (pressure up to about 0.6MPa) . With steel plate cooling , heating process can be finished (takes about 40 minutes ) . If the damaged place is larger than the heating steel plate, heating the center first, then heat the two side in order. When heat next part, the heating steel plate should overlap 15mm in the position of the last heating place.
