specific Embodiment approach

[0014] Take the case where the notch size is 50mm and the fenders are four layers as an example,

[0015] 1. Grinding

[0016] Grind and clean the damaged part of the fender that needs to be repaired at a distance of 35cm from the edge to the outside.

[0017] 2. Initial fixes

[0018] After leveling the parts to be repaired, apply primer evenly, and paste the cord fabric layer at the damaged part vertically to the center of the damaged part of the fender, and compact it.

[0019] 4. Strengthen repair

[0020] Spray polyurea at least 1mm thick on the damaged fender, then spread dipped canvas or cord fabric, spray polyurea again, repeat the above operation, spray polyurea four layers, after the last spraying is completed, cool and solidify for 24 hours, The fenders are now ready for use.

Abstract

The invention relates to an air bag repair method. The method is characterized in that an air bag is subjected to reinforced repair on the basis of initial repair, reinforced repair is carried out by adopting polyurea and gum dipped canvas or tyre fabrics, the strength and toughness meeting fender requirements can be completely achieved, the repair technology is economical, practical, simple, convenient and applicable to various fenders, particularly large fenders, and capital is greatly saved for the ship supplementary business.

Description

technical field [0001] The invention belongs to the field of ships, in particular to an airbag repair method. Background technique [0002] Inflatable or filled rubber fenders (airbags) are installed on docks or ships to absorb the collision energy between ships and docks or ships when docking or mooring, and to protect ships and docks from damage. supplies. Filled rubber fender has high energy absorption and reaction force, and has the advantages of low cost, long service life, simple installation and maintenance, etc. Since the inflatable or filled fender is a new type of fender, it is mostly used in harsh environments, such as offshore drilling platforms, etc., and the probability of fender damage is high. Once damage occurs, the user will repair the rubber fender according to the traditional method. The method has the problems of poor effect, long time, and high cost, especially the repair of large fenders is difficult, and often cannot be used after repair, the releva...
