利用化学转化与热处理的方法在钢铁表面制备了一种防结蜡涂膜,在含蜡的油水环境中,涂膜表面几乎没有蜡晶的沉积粘附,钢铁表面经过这种处理之后表现出了很好的防结蜡效果。研究表明,水和液体石蜡对涂层膜的润湿性不同是防结蜡的重要因素,在水中,蜡在这种涂膜表面的接触角高达158°,表现出明显的亲水憎油特征,这使得涂膜在含水原油中优先吸附一层水膜,而这层水膜可以阻止含蜡油水相与钢铁表面的直接接触,从而抑制蜡晶的沉积与粘附。
A method of chemical conversion and heat treatment was used to prepare an anti-wax coating film on the steel surface. In the wax-containing oil-water environment, there was almost no deposition of wax crystals on the surface of the coating film. After the steel surface was treated, Very good anti-wax effect. Studies have shown that the different wettability of water and liquid paraffin on the coating film is an important factor in wax prevention, the wax in the water, the contact angle of this coating surface up to 158 °, showing a clear hydrophilic oil-oleaginous characteristics , Which makes the coating preferentially adsorb a water film in the crude oil, and the water film can prevent the waxy water phase from directly contacting with the steel surface, thereby inhibiting wax crystal deposition and adhesion.
