Embodiment Construction

[0027] The present invention will be further described below in conjunction with drawings and embodiments.

[0028] Such as figure 1 , figure 2As shown, the test device of the present invention mainly includes a main working tank 1, a water storage tank 26, a constant temperature water bath 27 and a main control panel 25, etc. The main water tank 1 is filled with working solution (seawater or simulated seawater), and the sample holder 5 is installed on On the side wall of the main working box 1, it is used to install individual or electrical specimens. The blade-type rotating sample rack 2 is installed in the middle of the main working box, and the speed changer 37 is driven by a speed-regulating motor 36 arranged outside the main working box to drive the sample rack 2 to rotate. The upper part of the water storage tank is provided with a detachable baffle plate 6, which is used to prevent seawater from splashing to the upper sample and cover plate 8. Temperature sensor 7 ...

Abstract

A marine corrosion simulated accelerated test device belongs to the environmental corrosion test device technical field. The marine corrosion simulated accelerated test device is composed of a main operation box, a storage tank, a transmission system, a water-bath heating system and a main control panel. The main operation box comprises a fixation sample rack and a blade type rotary test rack which is driven to rotate by the transmission system on the exterior of the box, an infrared heating system, an air admission / exhaust system, a dehumidification system and a liquid-level sensing system, and a peristaltic pump set between the main operation box and the storage tank for transmitting the sea water. The marine corrosion simulated accelerated test device can realize the wet-damp alternation, the control of different corrosive gas environments and the simulation of the different marine corrosion regions and perform the indoor simulation / accelerated corrosion test under multi-factor complex marine environment through controlling the test parameter and process. The marine corrosion simulated accelerated test device is suitable for performing the corrosion simulated accelerated tests of various materials under marine environment.

Description

technical field [0001] The invention relates to a material corrosion test device, in particular to an indoor simulated acceleration test device for marine environment corrosion. Background technique [0002] The marine environment is one of the most severe natural environments for material corrosion, and the loss of materials caused by corrosion in the marine environment accounts for about 1 / 3 of the total corrosion loss. Seawater is a kind of natural electrolyte with complex composition. In addition to containing a large amount of salt, it also contains dissolved oxygen, marine organisms and decaying organic matter. At the same time, the temperature, flow rate, and pH value of seawater all have an impact on seawater corrosion. Therefore, the corrosion of metal materials in the marine environment is very serious. Generally, according to the ocean zone where the material or structure is located, it is divided into five typical corrosive environment areas: marine atmosphere ...
