Hollow layer can be installed leak detection instrument, at original oil tank wall brushing adhesive-layer, paste soft outsideLayer, at soft outer brushing adhesive-layer, pastes hollow layer, adopts at hollow layer brushing adhesive-layer bondingSoft internal layer, its structure is soft internal layer from the inside to the outside, hollow layer and soft skin, soft internal layer is fixedA closed cavity of composition after connecting, hollow layer connects in length and breadth.
After tested, withstand voltage of the present invention is all greater than 0.08MPa, proper operation pressure-2kPa～3kPa,Heatproof is-20 DEG C～50 DEG C. The inspection of positive/negative-pressure air tightness test is normal.
The present invention can make up raw steel liquefaction in-tank corrosion defect, and it is repaired and reinforcement. Even oil tankShell produces local corrosion, as long as inner canister can keep integrality, oil leak will never occur. The present inventionThe three-dimensional hollow liner of polymer composite of transforming for gas station's sunken tankers was to both burying with gas stationGround individual layer steel oil tank is transformed, and its maximum feature is both to have realized the anticorrosion of individual layer tank and environmental protection is wantedAsk, avoided again extensive civil engineering excavation.
The present invention saves cost, economizes on resources, and the downtime is short, and it is convenient to install, and mechanical strength is high, asThe abilities such as bearing capacity, impact resistance, damping property are outstanding, have the spy of oil resistant, water-fast, leakproof, environmental protectionProperty.
Above-described specific embodiment, the technical problem to solution of the present invention, technical scheme and usefulEffect further describes, and institute it should be understood that and the foregoing is only concrete reality of the present inventionExecute example, be not limited to the present invention, within the spirit and principles in the present invention all, that does appointsWhat revises, is equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
