Dry and wet cycle ultraviolet light automatic corrosion test chamber and test method

Abstract

The invention simulates the dry-wet cycle ultraviolet light automatic corrosion test box and the test method for simulating the degradation of organic materials in the tidal zone in the marine environment. The inside of the box is equipped with a parallel ultraviolet light source system, an adjustable sample hanger and a temperature detection system. There is an electric lifting device in the middle of the top surface of the cabinet, and the rigid connection directly below the electric lifting device is connected to the adjustable sample hanger, and the adjustable sample hanger is equipped with corrosion samples; an exhaust cooling system is also installed on the top surface of the box. And the total control system; the adjustable sample hanger is composed of adjusting bolts and two identical sample stands; each sample stand has an adjustable sample hanger support rod, a sample support and a lateral support rod, The corrosion sample is installed on the sample support; the dry-wet cycle, ultraviolet light source, temperature probe and ventilation cooling system are controlled through the linkage of the general control system, and the electric lifting device is automatically lifted and lowered at regular intervals, with a high degree of automation, which improves the experimental results reliability.

Description

technical field [0001] The invention relates to a corrosion test device and method, in particular to a test box and a test method for simulating the degradation of organic materials in a tidal zone in a marine environment, which are widely used in the evaluation of the protective performance of organic coatings and the life evaluation of other organic materials. Background technique [0002] The marine environment has the characteristics of high humidity, high temperature, high concentration of corrosive media, strong ultraviolet radiation, etc., and various environmental conditions change frequently, so various materials corrode and deteriorate quickly, especially the degradation and failure of organic materials in the marine environment is particularly rapid. Organic materials located in the tidal zone of the ocean rapidly fail under the dual effects of alternating dryness and wetness and strong ultraviolet light irradiation. Therefore, it is of great significance to grasp ...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problems of long on-site corrosion test period in the tidal zone, difficulty in collecting corrosion results and data, and the existing simulation test device cannot accurately control relevant parameters and consume a lot of manpower, the present invention proposes a combination of dry and wet alternating and ultraviolet light irradiation. Automatic corrosion test chamber and test method, realize precise automatic control of relevant corrosion parameters such as ultraviolet light source, temperature, dry and wet cycle through programmable controller
