Embodiment Construction

[0029]Such asFigure 1 to 8As shown, the material corrosion rate and the wall wetting characteristic test system include a control terminal, a water wetting tester 3, an electrochemical work station 2, and a high speed camera 4, and the control terminal of the present invention is a computer 1, the computer 1 connected electrochemical workstation 2, high speed camera 4 and related electronically controlled components within the water moisture tester 3.

[0030]The water moisturizing tester 3 includes a separatory funnel 8, a glass cover 5, and a test piece holder 12, and a sealing cover 6 is provided at the top of the glass cover 5, which is a cover, which is convenient in the open state. Tester adjusts the test piece holder 12, improves the test accuracy; in the closed state, the sealing cover 6 has high sealing, prevents volatilization of the experimental liquid. A sealing gasket 11 is also provided between the sealing cover 6 and the glass cover 5. The sealing gasket 11 fills the gap...

Abstract

The invention discloses a test system for material corrosion rate and wall surface wetting characteristics, which includes a control terminal, a water wetting tester and an electrochemical workstation. The lower end penetrates into the cavity in the glass cover, and an electric valve is provided on the separating funnel; a test piece support is installed in the glass cover, and electrodes are clamped on the test piece support, and the electrodes are connected to the electrochemical workstation. The present invention studies the wettability and corrosion of materials and the relationship between them by changing various parameters; it can also be used to study the damping characteristics of oil film on water wetting, corrosion and the correlation between them, and the front and rear droplet These studies will provide important theoretical basis and practical guidance for engineering.

Description

Technical field[0001]The present invention belongs to the field of material testing, and specifically, the material corrosion rate and the wall wetting characteristic test system are related.Background technique[0002]Wetrability refers to the ability of a certain liquid to spread or extends in a particular solid surface, or represents two mutually incompatible liquids, and a liquid is first wetting the surface of the solid surface. During the process of oil mining, processing, refining, the medium is generally existing in multi-phase flow forms such as oil-water, oil-gas-water, oil-gas. Corrosive medium (such as H2S, CO2, O2Elements such as HCl have different solubility in each phase, and in contact with the material in the flow process, different wetting properties and corrosion rates are formed. Therefore, the caused corrosion process tends to have local and sudden, unable to perform precise prediction and prevention and control.Inventive content[0003]It is an object of the presen...
