Atmospheric corrosion simulator capable of adjusting temperature, humidity, ultraviolet light and pollution gas

Abstract

The invention relates to an atmospheric corrosion simulator capable of adjusting temperature, humidity, ultraviolet light and pollution gas. The atmospheric corrosion simulator consists of an air compressor, a purifying and drying system, a humidifying system, a pollution gas generating and controlling system, a mixing box, a relative humidity detector, a constant-temperature water bath and an atmospheric corrosion simulation test box, wherein the purifying and drying system consists of a needle valve, a rotor flow meter and four organic glass tubes which are filled with purification components; through the humidifying system, wet air is formed by dry air through a water tank which is filled with medium-temperature bubbling distilled water; a tail gas absorbing device consists of different washing bottles which are filled with diluted hydrochloric acid and diluted sodium hydroxide solutions; an ultraviolet light system is used for adjusting and controlling the type and the strength of the ultraviolet light in the atmospheric corrosion simulation test box; the purifying and drying system, the humidifying system and all pipelines are fixed on a frame. Through using the atmospheric corrosion simulator, the efficiency of durability research on materials in a marine pollution atmosphere can be greatly improved; meanwhile, the pollution conditions can be controlled precisely; compared with a conventional method, the atmospheric corrosion simulator is more approximate to the accrual engineering application condition.

Description

technical field [0001] The invention belongs to the technical field of material engineering, and in particular relates to an atmospheric corrosion acceleration simulation device capable of adjusting temperature and humidity, ultraviolet light and polluted gas. Background technique [0002] Environmental parameters in the atmosphere, such as temperature, humidity, wetting time, polluted gases, suspended solid particles, etc., have a serious impact on the atmospheric corrosion of materials. With the development of society and the deterioration of the natural environment, the reliability of materials in the natural environment is more challenged. [0003] With the rapid development of the global ocean strategy in recent years, the materials used in the marine environment have been more seriously challenged. In particular, the ultraviolet light in the marine atmospheric environment has an important effect on materials and coatings, and has a serious impact on their service li...

AI Technical Summary

Problems solved by technology

These methods provide great convenience for indoor research on the mechanism of atmospheric corrosion, but they do not take into account the combined effects of ultraviolet light, temperature, humidity, and pollutants in the marine atmospheric environment, and cannot simulate the real atmospheric environment well. Reliability studies of materials used in the environment are of little significance
