基酸塩が前記のような海息付着生物の成長を著しく抑制
することを見い出した。Thermal power plants and various factories that use seawater use seawater creatures (especially mussels, barnacles, etc.) in their cooling water systems.
Water beetles; bryozoans; moths, etc.) are attached to the plant, reducing its functionality. Among them, purple snails adhere to each other and grow quickly. For this reason, the purple mussels that attach to the bottom cannot absorb enough nutrients and oxygen and die. As the mussels die, their legs attached to the wall become weaker, and they fall off due to water pressure, etc., causing blockages in the cooling tubes, blocking the flow of seawater and reducing their functionality. In order to solve this problem, we have now discovered that the aliphatic amine represented by the above general formula or its monobasic acid salt significantly suppresses the growth of the above-mentioned sea-breath attached organisms.

対する脂肪族アミンまたはその一塩基酸塩の生理作用は
全く知られていない。Conventionally, aliphatic amines have generally been used as disinfectants, algae agents, corrosion inhibitors, etc., and are known to have activity against bacteria, molds, and algae. , water bugs, bryozoans, ascidians, etc., have significantly different living functions from fungi and algae, and as far as the inventors of this invention know, aliphatic amines or their monobasic acids have no effect on the above-mentioned marine enzoosis. The physiological effects of salt are completely unknown.

付着生物の付着成長時に、少量海水系統に添加すること
により、その成長を抑制し付着を防止しうる。By adding a small amount of the aliphatic amine or monobasic acid salt used in the present invention to the seawater system when sea breath attaches and grows, the growth can be suppressed and the attachment can be prevented.

い。Examples of monobasic acid salts of aliphatic amines that can be used in the present invention include hydrochlorides, acetates, and formates of aliphatic amines as described above. The amount of aliphatic amine or its monobasic acid salt to be added according to the method of the present invention is generally injected in an amount of 0.03 to 3 feet per flow rate of seawater for 1 to 24 hours a day.

用するのが好ましい。The amount to be added may vary depending on the type of compound, as its physiological activity against sea-breath organisms varies. In addition, if the amount of sea-breath attached organisms is particularly large, it is desirable to increase the amount. The aliphatic amine or monobasic acid salt thereof used in the method of the present invention is preferably diluted with water, methanol, ethanol, dimethylformamide, methyl cellosolve, or the like.
次に実施例を挙げてこの発明を説明する。Next, the present invention will be explained with reference to Examples.
