文章摘要
Abstract: Understanding the hydrate adhesion is important to tackling hydrate accretion in petro-pipelines. Herein, the relationship between the Tetrahydrofuran (THF) hydrate adhesion strength (AS) and surface stiffness on elastic coatings is systemically examined by experimental shear force measurements and theoretical methods. The mechanical factor-elastic modulus of the coatings greatly dictates the hydrate AS, which is explained by the adhesion mechanics theory, beyond the usual factors such as wettability and structural roughness. Moreover, the hydrate AS increases with reducing the thickness of the elastic coatings, resulted from the decrease of the apparent surface elastic modulus. The effect of critical thickness for the elastic materials with variable elastic modulus on the hydrate AS is also revealed. This study provides deep perspectives on the regulation of the hydrate AS by the elastic modulus of elastic materials, which is of significance to design anti-hydrate surfaces for mitigation of hydrate accretion in petro-pipelines.
