Embodiment 1

[0054] like figure 1 The shown anti-corrosion structure for the edge plate of an oil depot storage tank includes an anti-corrosion primer layer 4, a flexible slope-seeking layer 3 arranged on the outside of the anti-corrosion primer layer 4, and a first slope-seeking layer arranged on the outside of the flexible slope-seeking layer 3. The anti-corrosion oil tape layer 5 and the second anti-corrosion oil tape layer 6 covering the outside of the first anti-corrosion oil tape layer 5, and the anti-corrosion primer layer 4 includes a storage tank for covering at least part of the outer side of the tank wall plate 10 Wall plate anti-corrosion section 4-1, edge plate surface anti-corrosion section 4-2 used to cover the upper surface of edge plate 2, edge plate outer side anti-corrosion section 4-3 used to cover the outer side of edge plate 2, used to cover storage The anti-corrosion section 4-4 on the upper surface of the tank foundation 1 and the anti-corrosion section 4-5 on the o...

Embodiment 2

[0088] like Image 6 As shown, the difference between this embodiment and Embodiment 1 is only that: the outer side of the first anti-corrosion oil tape layer 5 is also coated with an anti-corrosion primer for bonding with the second anti-corrosion oil tape layer 6 to strengthen Layer 13.

[0089]In this embodiment, when the construction temperature is -20°C to 15°C, the anti-corrosion primer reinforcement layer 13 is added in order to enhance the bonding strength of the first anti-corrosion oil tape layer 5 and the second anti-corrosion oil tape layer 6 . The anti-corrosion primer reinforcement layer 13 can effectively improve the bonding strength of the first anti-corrosion oil tape layer 5 and the second anti-corrosion oil tape layer 6 .

[0090] In the present embodiment, the anti-corrosion primer reinforcement layer 13 is made of petrolatum anti-corrosion primer, and the petrolatum anti-corrosion primer adopts the model STAC oil-based petrolatum primer produced by Centra...

Abstract

The invention discloses an oil depot storage tank margin plate anticorrosion structure. The oil depot storage tank margin plate anticorrosion structure includes an anticorrosion priming paint layer, a flexible slope finding layer arranged outside the anticorrosion priming paint layer, a first anticorrosion oil band layer arranged outside the flexible slope finding layer, and a second anticorrosion oil band layer covering the first anticorrosion oil band layer. The anticorrosion structure can effectively isolate corrosives such as water in a large range, has a certain anticorrosion thickness, and then can achieve an effective anticorrosion effect on an oil depot storage tank margin plate. The invention further discloses a construction method for the oil depot storage tank margin plate anticorrosion structure. The construction method includes the following steps: a first step, construction of the anticorrosion priming paint layer; a second step, construction of the flexible slope finding layer; a third step, construction of the first anticorrosion oil band layer; a fourth step, construction of the second anticorrosion oil band layer; and a fifth step, construction of a protection device. The construction method can rapidly and effectively achieve construction work of the oil depot storage tank margin plate anticorrosion structure.

Description

technical field [0001] The invention belongs to the technical field of anti-corrosion of storage tanks in oil depots, and in particular relates to an anti-corrosion structure for edge plates of storage tanks in oil depots and a construction method thereof. Background technique [0002] The storage tank of the oil depot is the most important facility and equipment in the oil depot, and it is also the biggest accident source in the oil depot. Therefore, it has always been listed as the most important safety protection object of the oil depot. Among the combined components of the oil depot storage tank, the tank bottom plate is the most important of all components, because the accident caused by the problem of the oil tank bottom plate is the most destructive. At the edge plate of the tank bottom plate, there are substrate surfaces composed of metal substrates, welds, building materials and other materials, which are easily corroded. Temporary measures can be taken to repair a...
