How to repair the airbag?
For the marine rubber airbag with small damage, as long as no serious aging (surface without cracking and tacky ) all can be repaired. Recommend using the heating method, process as below:
1. Clean airbag surface:
Rinse the airbag with water, make the damaged place (internal and external surface )clean, don’t have sediment, dirt, and oil, then dry the surface. When clean the airbag in water, the soaking time should be no more than 10 minutes.
2. Put the Nylon rubber:
Nylon rubber is rubber dipped Nylon cord fabric. The Nylon rubber used for airbag repairing should be the same as the airbag material. ( Our company can supply the Nylon rubber according to the customer request ). The Nylon direction of Nylon rubber should be the same as Nylon direction on the airbag wall. The laying method of Nylon rubber depends on different forms of breakage. The damage form can generally be divided into Longitudinal cracks ( Crack length direction along with the airbag extension ),Transverse crack (Cracks along the circumference direction outspread ),Nail hole (Including the shape less than 10cm diameter damage ). Operating steps as below:
(1) Mark the scope of repairing area out as the bound of the polish area. The repairing scope should extend to the surrounding of the damaged place, don’t ignore the hidden cracks. The extended range depends on the airbag size and damage size. Usually, extend 18~26cm larger than the damage place (Picture 6 for your reference).
(2) Polish the damaged surface needs to be repaired, till shows the Nylon fiber, but doesn’t damage the Nylon fiber.
(3) For the long crack, it has to be sewed with Nylon rubber first, please note that the distance from the pinhole to the crack is around 2~3cm, the space between the pinhole is around 10cm
(4) Clean the airbag surface need to repair using gasoline and waiting for the surface to be dry.
(5) Brush the glue on the surface. The glue is mixed pure rubber with gasoline. The weight proportion of pure rubber and gasoline is 1:5 . When brushing the first layer, thinner glue is better ( The weight proportion of pure rubber and gasoline can be 1:8 ). After the first layer become dry, brush the thick glue and wait until it dry.
(6) Seal the crack with the pure rubber strip with 1mm thickness and 1cm wider than the sewed area.
(7) Brush the gasoline and wait until the surface dry.
(8) Regarding longitudinal cracks, put one layer Nylon rubber with the width about 10cm vertically on the crack direction. For horizontal cracks and nail, holes can go directly to step 10.
(9) Brush the gasoline and wait until the surface dry.
(10) Put one layer Nylon rubber parallel to the longitudinal direction. The overlapped range around the crack should be 5cm larger and round the four corners
