Accelerated corrosion test device for nonferrous metal soil

Abstract

The invention relates to the field of accelerated corrosion research of nonferrous metal soil, in particular to an accelerated corrosion test device for the nonferrous metal soil. The accelerated corrosion test device is used for detecting and judging the corrosion degree of the soil in a test region to a metal material. A corrosive medium is placed in a conductive capacitor of the device. An upper rubber eraser and a lower rubber eraser are plugged at the upper part and the lower part of a metal pipe respectively. The metal pipe is arranged in the corrosive medium in the conductive capacitor. A direct-current positive terminal is connected to the upper end of the metal pipe and connected with an anode of a direct-current power supply through a lead wire. A direct-current negative terminal is arranged on the outer side surface of the conductive capacitor and connected with a cathode of the direct-current power supply through the lead wire. The corrosion of the nonferrous metal soil is accelerated through an external direct current, thus facilitating quick judge of the corrosion degree of the soil in the test region to the metal material. Related data of metal soil corrosion (weight loss) can be quickly obtained in 24 hours. The accelerated corrosion test device is simple in structure and convenient in measurement, is not limited by regions and is convenient to carry.

Description

technical field [0001] The invention relates to the research field of accelerated corrosion of non-ferrous metal soil, and specifically relates to a non-ferrous metal soil accelerated corrosion test device, which is used to detect and determine the degree of corrosion of the soil in the experimental area to metal materials. Background technique [0002] The normal non-ferrous metal soil corrosion test is buried in the soil environment of a specific area, which is taken out regularly for observation and weight loss is measured, but the time is very long. The non-ferrous metal soil accelerated corrosion test device is in the laboratory, and the soil in the experimental area is retrieved and loaded into it. In the container, the non-ferrous metal soil corrosion is accelerated by the external current, which can save the measurement time and cycle.
