Toxin containing perforated antifouling polymer nozzle grommet |
摘要 |
An apparatus and method for the elimination of marine fouling of marine mechanisms such as underwater fluid distribution emission systems. A grommet nozzle made of plastic materials containing an antifoulant and having a capability of easy installation forms a basic part of the apparatus. The grommet nozzle of the invention is formed of a polymer or a mixture of polymers containing a material toxic to calcareous marine organisms and capable of release of the toxic material into the environment at such a rate that the marine organisms grow extremely slow, yet the release rate is not sufficiently fast to be a toxic hazard to the surrounding environment.
