る。"Conventional technology" Cooling water intakes for power plants, seawater intakes, large diameter water pipes,
A technique (for example, Japanese Patent Nos. 854316 and 854319) in which a wax is applied to a water-contacting wall surface of a waterway, a waterway, or a ship after launching in order to reduce surface stains by living organisms is well known. .
「発明が解決しようとする問題点」 しかるに、叙上の従来の塗布要領では単に壁面に塗膜

しており、そのための下地処理や仕上げ処理について詳
細に指示していない。"Problems to be solved by the invention" However, in the above-mentioned conventional coating procedure, it is sufficient to simply form a coating film on the wall surface, and the usual surface cleaning is all that is required. Didn't tell you in detail.

が実情である。However, for ships, it is hardly used because it is inferior in the effect of mooring, and if wax coating is applied to the concrete wall of the waterway, it is demonstrated that the biofouling is extremely low for the first year or so. However, in the second year, the activity (smoothness) of the surface gradually decreases due to the adhesion of biological residues, scales, etc., and the effect of preventing biological adhesion also decreases.

付着防止効果の持続化技術が望まれている。However, the wax used is a mixture of paraffin wax and microcrystalline wax, which is used as a food additive, packaging, etc., is completely harmless, has no effect on fish and shellfish, and is suitable as a material for use. A technique for sustaining the biofouling prevention effect of is desired.

し、生物付着防止経費の低廉化を果した点にある。"Means for Solving Problems" and "Operation" The present invention has been made in view of the above circumstances, and its gist is to provide a method for cleaning kerosene after cleaning the wall surface prior to wax application. The surface of the wall whose surface has been cleaned by a flame is burned to burn off biological residues and improve the adhesion of wax to the wall, and the wax surface is heated and melted after applying the wax, and the mist of the surface wax is melted and integrated. In addition to measuring the temperature, a process to heat the wax surface again with a flame such as kerosene in order to allow the wax to melt and infiltrate into the fine pores on the wall surface, and to use a water jet or an underwater disk sander for half a year to one year after the start of use Prevention of biofouling by wax by setting a surface cleaning process to remove wax larvae on the wax surface and measure activation of the wax surface. The effect is maintained and the cost for preventing biofouling is reduced.

果は表面の物理的性質に依存する。In a waterway with a constant flow velocity, by coating the concrete wall surface with a wax, the surface is made smooth and the flow velocity on the wall surface is increased to prevent the attachment of biological larvae. Fall,
The total amount of shellfish (mainly mussel) can be reduced by stopping the growth, but this is because the wax surface has extremely low surface tension, so that larvae attach and secrete proteins and stick to them. The effect depends on the physical properties of the surface.

Paying attention to the fact that the adhesion is maintained and the effect is maintained on the surface activation, after the normal surface cleaning is completed as a base treatment, the burner burns to burn off the biological residues and the wall surface. Was preheated to prevent the sprayed molten wax from becoming mist and to improve the adhesive force of the wax.

入することを利用し、更に付着力の向上を得た。Further, the reheating, which is usually performed for the purpose of polishing the wax after the application of the wax, has a heat-sealing function and penetrates into the fine voids on the wall surface, and the adhesive force is further improved.

る。Furthermore, during the latter half year to one year after the start of use, before the light weight larva attached to the wax surface destroys the wax coating film, the surface is cleaned with a water jet or an underwater disc sander. By removing the wax, it is possible to prevent the wax surface from being ruined, and in particular, to prevent the growth of barnacles where mussels tend to form a community. It was discovered that the antifouling effect of wax can be sustained for a certain period by performing this treatment regularly.
「実施例」 以下これを実施要領にて詳細に説明する。"Example" Hereinafter, this will be described in detail in accordance with a practical procedure.
1.施工前の表面処理 ワックス塗布前のコンクリート壁面処理 ワックス塗布に先だち、コンクリート表面をサンダー
等で清掃するが生物の残渣等は完全に除去されない。1. Surface treatment before construction Treatment of concrete wall surface before application of wax Prior to application of wax, the concrete surface is cleaned with a sander etc., but biological residues etc. are not completely removed.
従ってサンダー掛けの後、大型燈油バーナーで表面を
炙り生物残渣等を焼くことにより、ワックスを塗布しや
すい表面を形成させる。Therefore, after sanding, the surface is roasted with a large kerosene burner to bake biological residues and the like to form a surface on which wax is easily applied.
2.ワックス塗布後の表面処理 ワックスをスプレーした後、更に上記バーナーで表面
を炙る。2. Surface treatment after applying wax After spraying wax, the surface is further broiled with the above burner.
この処理により、表面に付着しているワックス微粒子
は溶解しかつ、壁面に付着したワックスが再溶解し、コ
ンクリートの微細な空隙に滲み込み（熱封作用），強い
付着力が得られる。また、表面は極めて平滑になる。By this treatment, the wax fine particles adhering to the surface are dissolved and the wax adhering to the wall surface is re-dissolved, so that the wax permeates into the minute voids of the concrete (heat sealing action) and a strong adhesive force is obtained. Also, the surface becomes extremely smooth.
この処理により、従来行っていた表面清掃工程が省略
できる。By this treatment, the surface cleaning process which has been conventionally performed can be omitted.
3.使用後の表面処理 ワックス塗布後、半年〜１年以内にウォータージェッ
トまたは水中ディスクサンダー等により、表面を清掃す
る。3. Surface treatment after use After applying wax, clean the surface with a water jet or underwater disc sander within 6 months to 1 year.
この時点では、生物の付着量は少なく、付着力も弱い
ため、簡単に表面付着物を除去できるとともに、ワック
ス表面は再び活性化され防汚効果も増大する。At this point, the amount of organisms attached is small and the adherence is weak, so that the substances attached to the surface can be easily removed, and the wax surface is reactivated and the antifouling effect is increased.
特に、フジツボが付着し、ワックス塗膜を突き破って
生長する前にこの処理を行えば、ワックス塗膜の損傷を
防ぐとともに、フジツボ上に群落を形成し易いカラス貝
等の付着を防止できる。In particular, if this treatment is carried out before the barnacles adhere and break through the wax coating and grow, it is possible to prevent the wax coating from being damaged and to prevent the adhesion of crows and the like that tend to form a community on the barnacles.
また、この処理を定期的に行うことにより、長期に亘
る防汚効果を持続させることが出来る。Further, by carrying out this treatment regularly, the antifouling effect can be maintained for a long period of time.
ワックスコーティング施工前及び施工後、表面をバー

し、ワックス表面を滑らかにすると共にワックス塗布
後、一定期間後、水中に於て付着物を除去する組合せに
より、ワックス表面の活性を維持し、防汚効果の持続を
達成することが出来た。Before and after the wax coating is applied, the surface of the concrete is colored with a burner to make it suitable for application, the wax surface is made smooth, and after the wax is applied, a fixed period of time is followed by a combination of removing deposits in water. The activity of the wax surface was maintained and the antifouling effect could be sustained.
「発明の効果」 本方法を採用することによりワックス塗布による防汚
効果を低経費にて回復させることが出来、この工法を繰
返すことにより、従来の再塗布期間２年程に比べ５年以
上に延長することが出来る。このため年間の貝類除去費
用を大巾に低下させることが出来る。"Effect of the invention" By adopting this method, the antifouling effect of wax coating can be recovered at low cost. By repeating this construction method, the recoating period of 5 years or more can be achieved compared with the conventional recoating period of 2 years. It can be extended. Therefore, the annual shellfish removal cost can be greatly reduced.
