Application of Adhesives and Sealants in Ship Repair

       In the traditional shipbuilding industry, riveting, screw joint, welding and other fixing methods are mostly adopted. These fixing methods are restricted by the material material, shape, thickness, size, hardness and other aspects. For example, the connection and fixing of some thinner materials cannot obtain satisfactory connection and fixing effects, and affect the aesthetic properties of materials. The traditional riveting, screw joint, welding and other methods are easy to produce stress concentration when connecting the load-bearing structure, causing damage to the main structure of the ship, reducing the reliability of the ship, and increasing the maintenance cost of the ship. With the development of adhesives technology, adhesives gradually replace the traditional riveting, screw bonding, welding and other fixed methods. Due to the ship sailing long jiang, river, lake and sea in the complex environment, climate changeable, common sudden accident, therefore puts forward special demands on adhesive, such as must be resistant to salt water, atmospheric aging resistant, oil resistant, resistant to high and low temperature alternating, flame retardant, resistance to vibration, some hold non-toxic, tasteless adhesive for adhesives, beautiful, ship building general requirements on-site, simple and easy to process requirement.
