| 摘要 |
<p>The invention concerns a method for repairing membranes, such as ultrafiltration, nanofiltration and hyperfiltration membranes, in particular shaped like tubular hollow fibres, which consists, after detecting and locating a leak in a damaged fibre, in injecting therein a crosslinkable adhesive. Said method is characterised in that it consists in injecting into the damaged fibre a plug of an accurately measured amount of a single-constituent synthetic adhesive and in hardening said adhesive plug by crosslinking/polymerisation under ultraviolet radiation focusing said radiation on the fibre section to be repaired, under high flux density in the form of parallel beam, via a waveguide.</p> |
