Airbag repair

The damage forms of marine airbags can generally be divided into longitudinal cracks (the cracks extend along the length of the airbag), transverse cracks (the cracks extend in the circumferential direction), and nail holes (including disc-shaped damages within 10cm in diameter). The operation steps are as follows:

1) Delineate the repair range as the boundary of the polished surface. The repair range should extend to the cracks, and do not miss any hidden injuries. The expansion range depends on the airbag model and damage range. Usually, the 3-layer is 18-20cm; the 4-layer is 20-22cm; the 5-layer is 22-24cm; the 6-layer is 24-26cm.

Laying of rubber cord with longitudinal cracks

2) Polish and repair part of the surface until the fiber thread is exposed, but do not damage the fiber thread.

3) For longer cracks, first use cord to sew. The stitch hole position is about 2 to 3 cm away from the crack, and the stitch distance is about 10 cm.

4) Clean the surface of the part to be repaired with gasoline and let it dry.

5) Apply a layer of glue. The glue is prepared by soaking raw rubber in gasoline. The weight ratio of raw rubber to gasoline is usually 1:5, and the first layer should be slightly thinner (the weight ratio of raw rubber to gasoline can be 1:8). After the first layer of glue has dried, apply a thicker glue and let it dry.

6) Seal the crack with a raw rubber strip with a thickness of 1mm and a width of 1cm larger than the crack.

7) Brush the gasoline and let it dry.

8) For longitudinal cracks, first apply a layer of rubberized cord cloth with a width of about 10cm perpendicular to the crack direction. For transverse cracks and nail holes, step (10) can be performed directly.

9) Brush the gasoline and let it dry.

10) Lay a layer of rubberized cord fabric parallel to the longitudinal direction. The overlap area around the crack should be greater than 5cm, and the surrounding area should be cut into rounded corners

11) Brush the gasoline and let it dry.

12) Lay a layer of hanging rubber cord diagonally. The direction of the cords should be the same as the oblique cords (or reinforcement fibers) in the bag wall. The surrounding overlap area should be 1cm larger than the previous layer of rubber curtain fabric, and the surrounding area should be cut into rounded corners

13) Brush the gasoline and let it dry.
