Abstract
Description
15 20 25 30 35 2 förhindrar beväxning. Dessa substanser binds vid den marina konstruktionen antingen genom att denna är utförd av ett fibermaterial eller genom att den försetts med ett ytskikt av ett fibermaterial. 15 20 25 30 35 2 prevents overgrowth. These substances are bound to the marine structure either by being made of a fibrous material or by being provided with a surface layer of a fibrous material.
Med hjälp av fibrer som flockats genom känd teknik bildas en aktiv yta som kan vara förstorad med 30-50 gànger i förhållande till underlagets yta. Det har också visat sig att fiberflocket bildar en lämplig miljö för olika slag av bakterier och andra mikroorganismer. Bakterier som har en gynnsam inverkan mot de växter eller djur som utgör problem är tidigare kända, men det har före tillkomsten av föreliggande uppfinning inte varit möjligt att skapa en miljö i vilken bakterierna halls kvar pà en yta sä att en làngtidsverkan erhålles.With the help of fibers flocked by known technology, an active surface is formed which can be enlarged by 30-50 times in relation to the surface of the substrate. It has also been found that the fiber flock forms a suitable environment for different types of bacteria and other microorganisms. Bacteria which have a beneficial effect on the plants or animals which constitute problems are previously known, but before the advent of the present invention it has not been possible to create an environment in which the bacteria are retained on a surface so that a long-term effect is obtained.
En fiberflockad yta har visat sig bilda en sadan miljö som löser problemet att kvarhàlla aktiva substanser, bakterier eller andra mikroorganismer pá ytor som ligger i anslutning till eller under vattnet. Problemet med svar beväxning pà exempelvis skrovytor löses med en fiberflockad yta i vilken en lämplig substans, bakterie eller annan mikroorganism tillsatts.A fiber-flocked surface has been found to form such an environment that solves the problem of retaining active substances, bacteria or other microorganisms on surfaces adjacent to or underwater. The problem of responsive vegetation on, for example, hull surfaces is solved with a fiber-flocked surface in which a suitable substance, bacterium or other microorganism has been added.
Tekniken att belägga en yta med fiberflock är väl känd. Den bestàr i att en yta först belägges med ett adhesiv varefter elektriskt laddade fibrer fär landa i adhesivet och fastnar där. Adhesivet är ofta ett tvákomponents hartslim och fibrerna är vanligen syntetfiber av exempelvis polyamid.The technique of coating a surface with a fiber flock is well known. It consists in that a surface is first coated with an adhesive, after which electrically charged fibers land in the adhesive and stick there. The adhesive is often a two-component resin adhesive and the fibers are usually synthetic fibers of, for example, polyamide.
De fibrer som kan komma i fraga för föreliggande uppfinning är emellertid icke begränsade till någon speciell typ, utan även exempelvis kolfibrer, glasfibrer eller icke syntetiska fibrer kan komma i fraga. Speciellt lämpliga för att kvarhàlla bakterier är sàdana fibrer som binder en mindre mängd vatten såsom exempelvis polyamid, som normalt tar upp 2 - 4 % vatten. Även iháliga fibrer kan förväntas ha goda egenskaper för att kvarhàlla dessa substanser och organismer. 10 15 20 25 30 35 Cfš? fff' F* 3 \.«'Å'\.) k :xg Vid en föredragen utföringsform av föreliggande uppfinning utnyttjas en stor mängd fibrer soul vid elektrostatisk applicering till en stor del kommer att fixeras vinkelrätt mot underlaget. Fibertätheten kan uppgà till 50-300 fibrer per kvadratm, företrädesvis mer än 150 fibrer per kvadratmm, företrädesvis mindre till 0,5-5 mm, med en fibertjocklek mindre än 0,1 mm, än 0,05 företrädesvis mindre än 3 m. mm och en längd uppgàende Vid en andra föredragen utföringsform är den marina konstruktionen i sig' utförd. av ett garn eller nät av fibermaterial, varvid fiberlängden är àtskilligt längre. Dà dessa fibrer är av lämpligt slag för att binda den aktuella pàväxthämmande substansen, sä erfordras ej nagot fiberflock för att erhàlla den med uppfinningen asyftade effekten. I andra fall kan en fiberflockning vara lämplig även dà den marina konstruktionen är av fibermaterial.However, the fibers that may be contemplated for the present invention are not limited to any particular type, but also, for example, carbon fibers, glass fibers or non-synthetic fibers may be contemplated. Particularly suitable for retaining bacteria are those fibers which bind a small amount of water, such as, for example, polyamide, which normally absorbs 2-4% of water. Hollow fibers can also be expected to have good properties for retaining these substances and organisms. 10 15 20 25 30 35 Cfš? In a preferred embodiment of the present invention, a large amount of soul fibers utilized in electrostatic application will to a large extent be fixed perpendicular to the substrate. The fiber density may be 50-300 fibers per square mm, preferably more than 150 fibers per square mm, preferably less than 0.5-5 mm, with a fiber thickness less than 0.1 mm, than 0.05 preferably less than 3 mm. and a length upright In a second preferred embodiment, the marine structure itself is embodied. of a yarn or net of fibrous material, the fiber length being considerably longer. Since these fibers are of a suitable type for binding the antifouling substance in question, no fiber flock is required to obtain the effect intended by the invention. In other cases, a fiber flocculation may be suitable even when the marine structure is of fibrous material.
Bakterier som kan utnyttjas i samband med föreliggande uppfinning kan exempelvis vara av familjen Alteromonas, men även andra bakterier eller mikroorganismer kan utnyttjas enligt uppfinningen. Bakterierna kan appliceras pà ytor som är utförda av fibermaterial eller som tidigare belagts med fiberflock, men det är ocksa möjligt att förbehandla fibrerna med den aktuella bakterien innan de appliceras genom flockning eller innan de bearbetas till garn, nät eller att kvarhàlla bakteriekulturen i den fiberflockade ytan under lang tid, liknande. Det är troligen möjligt även under perioder med vinterförvaring under kyla e. dyl.Bacteria that can be utilized in connection with the present invention may, for example, be of the Alteromonas family, but other bacteria or microorganisms may also be utilized according to the invention. The bacteria can be applied to surfaces made of fibrous material or previously coated with fiber flock, but it is also possible to pre-treat the fibers with the bacterium in question before they are applied by flocculation or before they are processed into yarn, net or to retain the bacterial culture in the fiber flocked surface. for a long time, similar. It is probably possible even during periods of winter storage during cold or the like.
Bakterier som kan vara aktuella i detta sammanhang kan förvaras frystorkade under läng tid. Även andra substanser kan antingen appliceras pá tidigare fiberflockade ytor eller tillsättas till fibern innan denna appliceras.Bacteria that may be relevant in this context can be stored lyophilized for a long time. Other substances can also be applied to previously fiber-flocked surfaces or added to the fiber before it is applied.
