626 results about "Marine life" patented technology

Marine life, or sea life or ocean life, is the plants, animals and other organisms that live in the salt water of the sea or ocean, or the brackish water of coastal estuaries. At a fundamental level, marine life affects the nature of the planet. Marine organisms produce oxygen and sequester carbon. Shorelines are in part shaped and protected by marine life, and some marine organisms even help create new land. The term marine comes from the Latin mare, meaning sea or ocean.

Preparation method for tantalum-contained interlayer metallic oxide electrode

The invention belongs to the electrochemical technical field, and relates to a preparation method for a tantalum-contained interlayer metallic oxide electrode. The electrode is suitable for occasions including steel plate high-speed electroplating, seawater electrolysis marine life pollution and damage prevention devices, sodium hypochlorite electrolysis production devices, sewage treatment, cathode protection and the like in the electrochemistry industrial field. The main process comprises three steps, namely substrate pretreatment, tantalum-contained interlayer preparation and oxide coatingpreparation: firstly, a tantalum-contained interlayer is prepared on a titanium substrate by adopting a thermal decomposition method, and then a mixed metallic oxide electro-catalysis coating is prepared on the tantalum-contained interlayer; the mass percent purity of the metallic titanium substrate is larger than 99%; and the process is simple and convenient to carry out, the metallic oxide electrode with larger size or more complicated structure can be prepared, and the tantalum-contained interlayer can better protect the titanium substrate, delay the titanium substrate inactivation, improve the stability of the oxide electrode and prolong the service life.

Quaternary ammonium salt modified organosilicon polyurethane ocean antifouling paint and preparation method and application thereof

The invention discloses a quaternary ammonium salt modified organosilicon polyurethane ocean antifouling paint, the structure is shown as the formula (1); in the formula, an organosilicon soft segment containing quaternary ammonium salt side chain is an isocyanate hard segment; the quaternary ammonium salt modified organosilicon polyurethane ocean antifouling paint is prepared by the following steps: preparing 2,4,6-tri(3- chlorine propyl group)-2,4,6- trimethyl-ring trisiloxane; preparing 1,3-bi(3-(1-methoxy group-2-hydroxy propyl group) propyl group)-tetramethyl disiloxane; preparing 1,3-bi(3-(1-methoxy group-2-hydroxy propyl group) propyl group)-tetramethyl disiloxane; preparing dihydroxy ended chloropropylated polysiloxane; preparing polysiloxane compound containing the quaternary ammonium salt and hydroxyl; mixing the compound with the isocyanate, and adding gamma-aminopropyl triethoxy silane for chain extension to obtain a prepolymer, and the prepolymer being crosslinked and condensed in air. In the invention, the double effect of low surface energy and poison killing are achieved, so as to suppress the adsorption of marine organisms and kill bacteria adsorbed on the surface of a ship body through the quaternary ammonium salt.

Cleaning of submerged surfaces by discharge of pressurized cavitating fluids

InactiveUS20060151634A1Increased hydrodynamic dragDeterioration of operational specificationVessel cleaningPlug valvesHand heldEngineering
A fluid discharge apparatus adapted to discharge a cavitating stream of pressurized liquid along with the selective discharge of a secondary material, such as an abrasive, for removing dirt, debris, barnacles, marine growth, and other substances from submerged surfaces is provided. More particularly, the invention contemplates a introducing a pressurized liquid into a cavitation generating chamber to create and discharge a cavitating stream, and a secondary inlet for injecting abrasive material, such as silica, into the chamber to improve cleaning effectiveness. The gas bubbles within the cavitating liquid stream that essentially explode upon impacting debris resulting in tremendous pressure fluxuations provides improved effectiveness in removing debris and aquatic growth from the submerged surface. The combination of a secondary substance, such as an abrasive material, foam, or compressed gas enhances cleaning effectiveness. The invention further improves upon the control of such devices with controls, such as a pistol grip or rotational grip controllers, that allow the diver/operator to adjust flow rates and thrust without releasing his grasp. An improved hand-held apparatus is disclosed with a pistol grip and trigger actuator, and an improved wheeled vehicle is disclosed with improved control handles adapted to actuate valves and closure ports.
