How to Repair A Broken Ship Launching Airbag

How to repair a broken marine airbag? Marine airbags are mainly composed of natural rubber-based mixed rubber and nylon cord, so we can use some methods to repair them.

Marine launching airbags are made of tough nylon dipped cords, with thick texture and strong tensile strength. Generally, they will not be damaged within the normal service life. However, sometimes the customer does not clean the site during the launching process, causing the airbag to be cut by sharp iron sheets and other objects. So it needs to be repaired.

Leakage at the airbag mouth and the edge of the airbag flange

This situation is mostly caused by excessive extrusion and collision, and is generally repaired by cold bonding and adding raw rubber pads.

1. Cold bonding method: remove the flange, polish the leaking part (with gauze, etc.), clean it, apply adhesive, cut a rubber sheet of appropriate size (such as a car inner tube, etc.), polish it and paste it, then fix the flange and tighten it.
2. Adding raw rubber pad method: prepare a 20mm thick raw rubber sheet (raw rubber sheet generally uses raw rubber sheet with similar physical properties to rubber materials such as automobile tires). Remove the airbag flange, clean the leaking area, cut the appropriate size to block the leaking area, and then cut a piece of rubber sheet with the same size as the flange. According to the size of the airbag flange screw, dig holes in the area and paste it on the airbag, put on the flange, and tighten it.

Leakage of airbag body

This situation is mostly caused by collision and contact with sharp objects during use. Generally, cold bonding and hot patching methods are adopted.

1. Cold bonding method: prepare elastic cooked rubber sheets such as automobile inner tubes, polish them clean, and treat the damaged leaking areas in the same way. Use adhesives with high bonding strength and water resistance to paste and compact them.
2. Hot patching method: Generally suitable for large cuts. If the cut is less than 80mm, it can be repaired on site.
