Embodiment 1

[0032] A carbon steel storage tank lining epoxy resin construction process, comprising the following steps:

[0033] S1. Clean the inner surface of the storage tank;

[0034] S2. Coating a layer of primer on the inner surface of the storage tank, wherein the primer needs to be fully stirred during the preparation process, and left to stand for 30 minutes to fully mature before painting;

[0035] S3, scraping putty powder on the primer surface;

[0036] S4. Prepare the interlining rubber material, apply the interlining rubber material on the part where the putty powder is applied, and then paste a layer of glass cloth on the surface. After the glass cloth is naturally dried, attach two layers of glass cloth to the surface in turn, and three layers. The glass cloth is attached using the fish-scale laying method, that is, the latter layer of glass cloth is partially overlapped and laid on the previous layer of glass cloth; among them, the glass cloth is soaked with glue before u...

Abstract

The invention discloses a construction process of a carbon steel storage tank lined with epoxy resins. The construction process of the carbon steel storage tank lined with the epoxy resins comprises the following steps that S1, cleaning treatment is carried out on the inner surface of the storage tank; S2, the inner surface of the storage tank is coated with a layer of bottom paint, the bottom paint needs to be fully stirred in the preparation process, and standing for 30 minutes is carried out and coating and brushing are carried out after the bottom paint is cured fully; S3, putty powder isscraped on the surface of the bottom paint; S4, a lining cloth sizing material is mixed, the lining cloth sizing material is coated and brushed on a part on which the putty powder is scraped on, thenthe surface of the lining cloth sizing materials is pasted with a layer of glass cloth, after the glass cloth dries naturally, then the surface of the lining cloth sizing material is sequentially attached to two layers of glass cloth, three layers of glass cloth are attached and a fish scale type paving method is adopted, and the later layer of glass cloth is paved on the front layer of glass cloth in a partial overlapping mode; S5, the surfaces of the glass cloth are coated and brushed with finishing paint; and S6, the quality is inspected, and qualified acceptance is achieved. The construction process of the carbon steel storage tank lined with the epoxy resins is easy to operate, can improve the construction quality, reduce the cost investment, improve the construction efficiency, and prolong the service life of the storage tank.
