Air bag with high intensity and its manufacturing technique

Abstract

The invention is a high-intension gas cell and its facture. The gas cell comprises the cell body, the cell head and the air gate mouth. The cell body is composed of the inner sleeving layer and plural layers of curtain cloth. The cell head and the cell body are jointed together to form the conoid shape, the cell head is solidified with the air gate mouth. The facture is to longitudinal arrange the curtain cloth, adhere the two sides and roll them to barrel shape to be the inner sleeve. The demolishing inner pressure of the gas cell is higher than 1.11 MPa, and the cell wall is sealed well. The invention has a wide range of appliance.

Description

Technical field

[0001] The invention relates to a high-strength air bag and a production process thereof, in particular to an air bag used for the upper discharge and launching of ships and the production process thereof. Background technique

[0002] Airbag launching technology for ships first appeared in the early 1980s. Due to the low carrying capacity of airbags at that time, they could only be applied to small wide-bottomed barges with a self-weight of tens of tons, and it was difficult to break through the threshold of launching weight exceeding 500 tons. In order to meet the needs of the safe launch of larger ships, the strength of the airbag itself must be improved. The material selection, bladder structure, manufacturing method and process flow are the key factors that determine whether the strength of the airbag can be improved.

[0003] At present, the manufacturing process of marine airbags mainly has the following methods. One is to use the method of overlappin...
