A test device for simulating spray splash zone

Abstract

The invention relates to the technical field of material corrosion and protection, in particular to a test device for simulating a spray splash area. It includes a box body equipped with a solution circulation system, a spray generating device covered with a water-absorbing material coating layer is set in the middle of the box body, and a corrosion sample stand, a ventilation device, and a temperature detection and control element are set around the spray generating device. The spray generating device is respectively connected with the solution circulation system and the power device, and the power device is connected with the control system including program control. The invention can generate splash solution particles, simulate the spray splash environment, realize precise control of spray splash efficiency, spray splash rate, spray shape, etc., and make the simulated corrosion test results have good correspondence with the on-site corrosion results in the spray splash area. Therefore, the experimental efficiency is improved, manpower and material resources are saved, and the cost of the experiment is reduced; at the same time, the experimental data collection is convenient, which ensures the integrity of the experimental data and the reliability of the experimental results.

Description

technical field [0001] The invention relates to the technical field of material corrosion and protection, in particular to a test device for simulating a spray splash zone. Background technique [0002] Marine corrosion not only causes huge economic losses, but also creates potential safety hazards if not properly protected, affecting the normal operation of marine structures. Components in the spray splash zone are most severely corroded due to the coupling effect of various harsh environmental factors such as alternating dry and wet, fully inflated surface, sea water splash, and sunlight exposure. Design has important scientific significance. At present, the corrosion experimental research in the spray splash zone is mainly based on the on-site corrosion experiment. However, the on-site experiment is not only limited by geographical location, site conditions and other factors, but the experiment period is long and data collection is difficult. In addition, the on-site ex...
