Naprawa wewnętrznego płaszcza stalowego zbiornika podziemnego na paliwo płynne laminatem poliestrowo-szklanym

The article presents the results of numerical analyses and experimental tests, the aim of which was to evaluate the method of repairing the inner shell of a double-walled underground tank with a laminate coating made of polyester resin and glass mat, in the context of the impact of this coating on the strength parameters of the inner shell as well as the properties of the laminate during its long-term use contact with fuel. The results of experimental tests, including the determination of porosity and absorption, as well as the assessment of flammability of laminate samples, indicated important features of the laminate coating in the context of the fire hazard of the tank. The results obtained also indicated the need to continue work on the development of effective and safe repair technologies using composite coatings.
