る。[Operation] Therefore, the method for preventing leakage of the fluid storage facility of the present invention uses the sealing agent applied in the second to fourth steps to prevent the polymerization step 3
The sealing agent used in the present invention is obtained by mixing a vulcanizing agent into liquid synthetic rubber thiocol, and therefore, at room temperature for a predetermined period of time after vulcanization. It solidifies underneath to form a rubber-like elastic body. In general, vulcanized and hardened and solidified rubber bodies are not evident from the fact that molded products cannot be removed from the mold unless a release agent such as silicon is applied to the mold for molding rubber products. Although it is inferior to epoxy resin, it has strong adhesion, strong oil resistance, and of course has high elasticity, so it follows local movement and deflection of fluid storage equipment, and is less likely to crack or peel. Is provided.

る。Further, the present invention is to apply the sealing agent a plurality of times in the second to fourth steps, the properties of the sealing agent in each of these steps,
In particular, the viscosity can be appropriately changed, and the first coating layer B1 applied in the second step and the finishing layer B3 applied in the fourth step can be applied in a state of high fluidity. It can be reliably applied to uneven surfaces, and it can be applied in the third step by reducing the amount of the vulcanizing agent to be mixed to increase flexibility and adhesion. The main coating layer B2 can be made to be laminated thicker in a state where the fluidity is small and the viscosity is high, as a result, this pre-coating layer B1 is as an adhesion basic surface, and the main coating layer B2 is as a pressure-resistant surface, The finishing layer B3 interacts with the final coating layer as an anti-peeling surface.

A predetermined width along 3a is polished with a buff or sandpaper, or wiped with a methyl-ethyl-ketone cleaning liquid. In the case where the fluid storage facility is a rivet connection structure using steel plate 1,1 rivets 2,2,2..., The width of the cleaning surface A is such that the rivets 2,2,2. Like that.

体裁を良くすることは無論望ましいことである。In the second step, an encapsulant obtained by mixing a vulcanizing agent with liquid synthetic rubber thiocol is applied as a first coating layer B1 on the entire surface of the cleaning surface A. The application of the first coating layer B1 is generally performed by brush coating, but may be performed by spray coating. In addition,
The entire surface of the cleaning surface A does not necessarily mean the entire area that has been cleaned. The cleaning surface A having a somewhat wide width is formed, a tape is attached to an end portion, the cleaning surface A is limited by the tape, and a finished appearance is obtained. Better is, of course, desirable.

積層して本塗り層B2を積層する。The third step is to fill a caulking gun with a high-viscosity sealant of the same material as the above-mentioned sealant that has reached a predetermined viscosity after a certain period of time after vulcanization, and using this caulking gun, The sealing agent is injected into the overlapping step portion 3 or the concrete seam 3a from the top of the pre-coated layer B1, and the sealing agent is laminated thicker on the upper surface of the rivet 2 and near the periphery thereof. The main coating layer B2 is laminated.
この第三工程に使用される封滅剤は、第二工程及び後
述する第四工程で使用されるものと全く同一のものを使
用するが、多少加硫剤を多く混入したものを使用するこ
とが望ましい。加硫剤が多いと固く固化して漏洩流体圧
に対して充分な耐力が得られることになるからである
が、必要以上に加硫剤を混入すると弾性・付着力・引裂
き強度ともに低下するので注意が必要である。The sealing agent used in the third step is exactly the same as that used in the second step and the fourth step described below, but a mixture containing a little vulcanizing agent is used. Is desirable. This is because if the vulcanizing agent is too much, it will solidify and provide sufficient strength against leakage fluid pressure.However, if the vulcanizing agent is mixed in more than necessary, the elasticity, adhesion and tear strength will decrease. Caution must be taken.

ことが望ましく、特に錆の発生が多いリベッチ2の頭部
には厚めに本塗り層B2を積層するとよい。In other words, the main purpose of the main coating layer B2 is to seal the leakage gap, and the thickness of the leakage gap is large enough to withstand the pressurization because the pressure in the fluid storage facility is applied to the leakage gap. It is necessary to have a thickness of 1 to 2 mm or more in order to prevent the generation of rust due to the infiltration of moisture. Should be laminated.

のを防止する。The main coating layer B2 includes a portion where there is a possibility that there is a leakage gap between the overlapped step portion 3, the concrete seam 3a, and the periphery of the head of the rivet 2, and the rivet 2 where rust is often generated.
May be applied only to the head or the like, but may be applied to other parts, that is, to the entire surface of the first coating layer B1, and further, if necessary, locally after the main coating layer B2 is solidified. A reinforcing coating layer B2 'may be applied so that the main coating layer B2 does not peel off. This reinforcing coating layer B2 'is composed of the first coating layer B1 and the main coating layer.
It is applied over the edge of B2 to prevent the main coating layer B2 from peeling off.

Further, this finishing layer B3 also has an action of preventing peeling of the main coating layer B2, and therefore, it is applied not only on the upper surface of the locally applied main coating layer B2 but also on the entire surface of the pre-coat layer B1. It has become. Although not shown, when the main coating layer B2 is laminated on the entire surface of the first coating layer B1, the finishing layer B3 projects further outward from the main coating layer B2 and is applied to one surface of the steel material or the like. Good to do.
