Corrosion testing apparatus and implementing method thereof

Abstract

The invention discloses a corrosion testing apparatus which comprises a corrosion water supply device, a constant-temperature water bath bed, a corrosion tube, a constant-temperature water bath and a constant-temperature water supply device. The corrosion water supply device is used for providing corrosion water; the constant-temperature water bath bed is used for heating (or cooling) the corrosion water and keeping a constant-temperature state; the corrosion tube is placed in the constant-temperature water bath and is used for placing a rock sample so as to perform a corrosion reaction on the heated (or cooled) the constant-temperature corrosion water and the rock sample and collecting corrosion liquid after the reaction; the constant-temperature water bath is used for heating (or cooling) the corrosion tube to the same temperature with the temperature of the corrosion water, and keeping a constant-temperature state; the constant-temperature water supply device is used for respectively supplying constant-temperature water to the constant-temperature water bath bed and the constant-temperature water bath so as to enable the constant-temperature water bath bed to heat (or cooling) the corrosion water and enable the constant-temperature water bath to heat (or cooling) the corrosion tube. The corrosion testing apparatus lays a theoretical foundation for establishing a hydrochemical dynamics-fractal exponent evaluation mathematical model of karst development intensity.

Description

technical field

[0001] The invention relates to a corrosion test device and a realization method thereof. Background technique

[0002] Dissolution, also known as dissolution erosion, refers to the geological process in which any component in rocks, such as particles, matrix, cement and metasomats, dissolves in water under the action of formation water or solvents such as organic acids or carbonic acid. Generally, the dissolution and movement of soluble substances in rocks by surface water or groundwater is defined as dissolution.

[0003] In modern engineering, such as underground buildings, dam foundations, traffic tunnels or other rock-soil bodies (such as concrete), the dissolution phenomenon is very common, and has become one of the focal issues in the field of construction rock-soil durability research. In the limestone area, the dissolution is most obvious.

[0004] At present, the research on the dissolution phenomenon in the engineering field has been relatively m...
