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
