Test device for simulating splash zone

Abstract

The invention relates to the technical field of corrosion and protection of materials and particularly relates to a test device for simulating a splash zone. The test device includes a box body which is provided with a solution circulating system. A splash generating device, which is wrapped by a water-absorbing material wrapping layer, is disposed in the middle of the box body. A corrosion sample rack, a ventilating device, a temperature detecting and controlling element are disposed around the splash generating device. The splash generating device is respectively connected to the solution circulating system and a power device which is connected to a controlling system in which program controlling is contained. By means of the test device, a splash solution particle can be generated and a splash environment can be simulated. Splash efficiency, splash speed and splash form can be accurately controlled so that an excellent correspondence is achieved between a simulation result of a corrosion experiment and a site corrosion result in the splash zone is achieved, thereby increasing experimental efficiency, saving labor intensity and resources and reducing an experimental cost. Meanwhile, experimental data is convenient to be collected so that integrity of the experimental data and reliability of the experimental result are ensured.

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 area. 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...
