Abstract

The invention discloses a flexible composite film, a flexible oil bag comprising the flexible composite film and a storage tank comprising the flexible oil bag. The flexible composite film comprises a first oil-resistant layer, and a polyester woven fabric, a second oil-resistant layer, a barrier layer and a static dissipation layer which sequentially cover the inner surface of the first oil-resistant layer; and the tensile strength of the flexible composite film is greater than or equal to 92 MPa. On one hand, the flexible composite film designed by the invention not only has very good rebound resilience, but also has very strong tear and puncture resistance, the flexible oil bag formed by the flexible composite film is used for separating an oil product from the air, so that'big breathing and small breathing 'are on the same side as the air, the volatilization space is eliminated, the volatilization loss is inhibited, flammable and combustible oil gas is prevented from being formed, meanwhile, random deformation is ensured under the condition of no fracture, and the safety index is improved; and on the other hand, the flexible oil bag and the storage tank are effectively combined, so that a double-layer gap is formed between tank walls of the storage tank to monitor leakage, and the technical problems existing in the storage and transportation industry are solved.

Description

technical field [0001] The invention relates to the technical field of oil and gas storage and transportation, in particular to a flexible composite film, a flexible oil bladder containing the same and a storage tank containing the same. Background technique [0002] The storage tanks used in oil and gas storage and transportation are generally atmospheric storage tanks. When oil products enter and exit the storage tanks, the air in the tank needs to be inhaled or discharged to maintain pressure balance, resulting in "big breathing"; , resulting in a change in volume, in order to balance the pressure brought by the volume change, it needs to enter and exit air, resulting in a "small breath". "Small breathing" will cause oil volatilization, oil volatiles mixed with air to become oil gas, oil gas is flammable, explosive and pollutes the environment. Microscopically, volatilization is the process of liquid molecules leaving from the liquid surface. The liquid molecules collid...
