２回程度海上から陸上に引き上げて海洋生物を除去して

燃料費等の経費が嵩んだり、あげくの果てには船自体が
沈没してしまったりする為である。また、船や飛行機の
安全航行の為の役目を果たす浮標の場合も、同様に、海
洋生物が付着して浮標が片むいたり沈んだりしてしまっ
ては、その役目を果たせない為である。[Prior Art] For many years, ships, buoys, etc. had marine organisms such as oysters and barnacles attached to them, so once or twice every two years the marine organisms were removed from the sea by being pulled onto land. . The reason for this is that when marine life attaches to the bottom of a ship, the weight of the ship increases, which slows down the ship's sailing speed, increases fuel costs and other expenses, and ultimately causes the ship to sink. This is because they end up doing something wrong. Similarly, buoys, which play a role in the safe navigation of ships and airplanes, cannot fulfill their role if marine life attaches to them and the buoy becomes lopsided or sinks.

アン化合物で殺す方法であった。Conventionally, foreign-made paints containing a mixture of fluorine, cyanide, and copper powder have been commercially available as paints for preventing the adhesion of marine organisms to ships, buoys, and the like. This method used cyanide to kill any marine organisms that may be attached to it.

ておらず、付着防止効果は著大であった。[0009] The effect of preventing the adhesion of marine organisms was tested using the method described below. A steel plate with a thickness of 3.2 mm and a length and width of 200 mm x 200 mm was coated with a two-component epoxy resin as an undercoat and a heavy anti-corrosion paint (trade name: Polex) as an intermediate coat to form the test material. did. The test material was coated with a mixture of 60% by weight sinigrin and 40% by weight myrosinase and left in the sea for one year. After one year, no marine organisms had adhered to the test material, and the adhesion prevention effect was remarkable.

着したが、付着防止効果は充分あった。As another example, a mixture of 90% by weight sinigrin and 10% by weight myrosinase was applied as a top coat to the test material after the intermediate coating of the previous example, and the material was left in the sea for one year. After one year, a very small amount of marine organisms adhered to the test material, but the adhesion prevention effect was sufficient.

分あった。As yet another example, a mixture of 10% by weight sinigrin and 90% by weight myrosinase was applied as a top coat to the test material after the intermediate coating, and the material was left in the sea for one year. After one year, marine organisms were attached to the test material in a small amount, although slightly more than in the previous example, and the adhesion prevention effect was sufficient.

の付着をよく防止する。[0012] As for the mixing ratio of sinigrin and myrosinase, the preferred weight ratio (sinigrin:myrosinase) is (30:70) to (80:20), and more preferably (40:60) to (70: 30), and the most preferred is (60:40). Here, the enzymatic activity of myrosinase increases at temperatures above 25°C, so during the summer months when marine organisms such as oysters are likely to adhere to it, myrosinase hydrolyzes sinigrin well and releases decomposed products, allowing marine organisms to adhere to it. well prevented.

You are free to choose a paint that prevents the adhesion of marine organisms. Further, if a red, orange or yellow paint is used as the paint, the adhesion prevention effect will be further improved.

保つ。[0017] Hydrolyzing the glycoside with a hydrolase,
Marine organisms such as oysters and barnacles dislike the odor and taste of the resulting decomposition products, and it is possible to prevent these marine organisms from adhering to the product. In addition, the rate of progress of hydrolysis and the timing of the emergence of marine organisms (speed of attachment) are both affected by water temperature, and since they match well, the effect of preventing marine organisms from attaching can be maintained for a long period of time. .
【００１８】また、配糖体も加水分解酵素も人間に対し

い。即ち、海洋汚染を生じない。[0018] Furthermore, since both glycosides and hydrolytic enzymes are harmless to humans, they do not cause any damage to the marine environment. In other words, it does not cause marine pollution.
