8 Layer Ship Launching Airbags

The overall winding process ofp Ship Launching Airbags has strong bearing capacity

Advantages of Marine Airbag:

1. The construction of the 1, save a lot of money Ship airbag on the way, the water is a promising new technology, changing the repaired the ship can only adopt slipway, floating dock, the dock water way, thereby saving the chute, dock, the dock into the constructed a lot of money, and thus reduce the upfront costs of the construction yard.

2, greatly improve the ability of shipyard built Because the traditional way of fluctuation restricted the shipyard's production capacity, flexible fluctuation fundamentally changed the airbag to only use slipway, dock in the work of the traditional way of the ground can be used in the work of then use air bag launching way, so that it can greatly improve the repaired the ability of shipyard.

Multi-purpose Ship Launching Airbags:

Marine airbag can not only provide buoyancy for ship salvage, but also has great advantages in rescuing stranded ships. The airbag can be inserted into the bottom of the stranded ship. The airbag can be inflated to lift the ship, and under the action of towing or after thrust, the ship can enter the water smoothly.

Maximum working pressure of ship launching airbag:

The maximum working pressure of the Marine airbag shall be determined according to the diameter, number of layers and working height of the airbag. The maximum working pressure of all types of airbags is not the same. The general working pressure range is from 0.1MPa to 0.35MPa, and the specific pressure range shall be determined according to the actual situation

How to repair ship launching airbag

The damage forms of Marine launching airbag can be generally divided into longitudinal cracks, transverse cracks and nail holes.

The operation steps are as follows:

(1) mark out the repair range as the boundary of the polished surface. Repair scope to the crack around the expansion, do not omit hidden damage. The extension range varies depending on the type of airbag and the damage range, usually 18-20cm for 3-layer; 4-layer is 20-22cm; The 5th layer is 22-24cm; The six layers are 24-26cm.

(2) polish and repair part of the surface until the fiber line is exposed, but do not damage the fiber line.

(3) For long cracks, cord thread should be used first. The location of the stitching pinhole is about 2-3cm away from the crack, and the stitching needle spacing is about 10cm.

(4) clean the surface of the part to be repaired with gasoline and dry it.

(5) coated with a layer of glue. Slurry is made by soaking raw rubber in gasoline. The weight ratio of raw glue and gasoline is usually 1:5, and the first layer is slightly thinner (the weight ratio of raw glue and gasoline is desirable 1:8). After the first layer of slurry cool dry, then coated with a slightly thicker slurry and air dry.

(6) with a thickness of 1mm, width of 1cm than the crack sealing rubber strip.

(7) Brush the gasoline and dry it.

(8) For longitudinal cracks, a layer of hanging rubber cord cloth with a width of about 10cm is applied perpendicular to the direction of the crack.

(9) lay a layer of hanging rubber cord cloth parallel to the longitudinal direction. The lap area around the crack should be greater than 5cm and should be cut and pasted into rounded corners.

(10) lay a layer of hanging rubber cord cloth diagonally. The direction of the cord should be the same as that of the oblique cord (or reinforcing fiber) in the cyst wall. The surrounding lap area should be 1cm larger than the previous layer of hanging plastic cord cloth, and all sides should be cut and pasted into rounded corners.
