Abstract
The utility model discloses a test device for simulating a corrosion environment in a tide-difference zone of the ocean environment. A main body of the test device is a test box body. An elevation device is installed on a top panel of the box body, and a test hanger, an ultraviolet lamp tube and a corrosion medium test groove are arranged inside the box body. A porous separating plate is installed on the bottom part of the test box body, the porous separating plate is used for holding the test groove with the corrosion medium, and seawater or other corrosion medium is arranged inside the corrosion groove. A heater and a temperature sensor are installed in a space between the porous separating plate and the bottom surface of the box body. Fresh water is filled inside the test box, and water-bath temperature control is carried out. When a sample is completely soaked in the corrosion medium, the corrosion environment when tide rises in the ocean can be simulated. When the sample is lifted to leave away the liquid surface, the sample is radiated by the ultraviolet ray, and the corrosion environment of the sample being radiated by the sunlight can be simulated when the tide ebbs. Since the influence of the dry-wet alternation of the seawater and the radiation of the sunlight is comprehensively considered, the real corrosion environment can be approached, and an experiment foundation can be provided to research the corrosion prevention technology in the tide-difference zone.
Description
Technical field:
The utility model relates to a kind of marine corrosion simulated experimental provision, especially simulates the corrosion testing apparatus of tidal range district, ocean environment.
Background technology:
In ocean tidal range district, be coated with organic coating and be the steel construction process for protecting surface of normal employing, the useful life of organic coating mainly is subjected to the burn-in effects that periodicity sea water immersion effect that morning and evening tides causes and dried stage solar radiation cause.Carrying out the simulated experiment of respective environment, is the prerequisite of carrying out protective coating design, selection, life prediction and studying its corrosion failure mechanism.Once there was document to mention with alternation of wetting and drying soak test simulation dry wet alternating environment; Photoenvironment is simulated in also useful traditional ageing oven, but the former does not have coupling light aging, and the latter does not then consider the coupling dry wet alternating environment.So far do not see special report as yet at the corrosion simulated test unit in tidal range district.
Summary of the invention:
Technical problem to be solved in the utility model provides tidal range district, a kind of ocean corrosion simulated experiment device, and it can carry out the aging corrosion test of alternation of wetting and drying coupling light, can reflect the corrosion operating mode in tidal range district, ocean more exactly.
The technical scheme that its technical matters that solves the utility model adopts is, the height by the periodic variation sample changes the residing environment of sample.The external structure of experimental provision is a casing, adopt aluminium alloy or stainless steel to be welded, whole plate is all adopted at its end face, bottom surface, two sides and the back side, and its front panel then is divided into two parts up and down, lower part and base plate and biside plate are welded into one, and switching door then is processed on top.The inside of casing is followed successively by sample jacking gear, ultraviolet lamp tube arrange district, full bath unit from top to bottom.The sample jacking gear obtains mechanical support by the top panel of test casing.Lifting screw in the jacking gear passes chamber top board center, the hand-operated lifting disk is installed on the lifting screw and is positioned at the roof box top, and the sample hanger geometric center in the casing links to each other with the lower surface of lifting screw, sample then hangs from above on the sample hanger, like this, drive the lifting screw motion by manual rotation and lifting disk and just can realize moving up and down of sample hanger and sample.Above tank floor, be provided with dividing plate with holes, well heater and temperature sensor are housed in the space between dividing plate with holes and the casing.On dividing plate with holes, lay 6 glass test flumes, space mounting above the glass test flume has 8 ultraviolet lamp tubes, in two separate ranks, up and down four layers arrange, the front and back of the two row fluorescent tubes suspension sample that all has living space, sample hangs on glass test flume top, hold corrosive medium in each glass test flume, clear water is injected in the bottom of casing, and the water surface was not advisable not have the glass test flume.
The beneficial effects of the utility model are, ultraviolet lamp tube and the test flume that holds corrosive medium have been installed in the casing of experimental provision, at box top jacking gear has been installed, can regulate the suspension height of sample by rotating the lifting disk, thereby the control soak time of sample in corrosive medium and the irradiation time of ultraviolet light, simulated seawater alternation of wetting and drying and dried sunlit environment of stage in the oceanic tide difference ring border, thereby provide experiment basis for studying tidal range district's corrosion protection technology and corrosion failure mechanism.
Description of drawings:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural front view of tidal range district, the ocean corrosion simulated experiment device that proposes according to the utility model.
Fig. 2 is the structure vertical view of experimental provision shown in Figure 1.
Among the figure, 1. test casing, 2. lifting screw, 3. lifting disk, 4. sample hanger, 5. sample, 6. ultraviolet lamp tube, 7. test flume, dividing plate 8. with holes, 9. well heater, 10. temperature sensor.
Embodiment:
Fig. 1 and Fig. 2 are the experimental provision structural representation.The external structure of experimental provision is a casing 1, adopt aluminium alloy or stainless steel to be welded, its top panel, bottom panel, two side panels and backplate all adopt whole plate, its front panel then is divided into two parts up and down, lower part and base plate and two side panels are welded into one, and switching door then is processed on top.The inner structure of experimental provision is followed successively by sample jacking gear, ultraviolet lamp tube arrange district, full bath unit from top to bottom.The sample jacking gear obtains mechanical support by the top panel of test casing 1.Lifting screw 2 in the jacking gear passes test casing top panel center, hand-operated lifting disk 3 is installed on the lifting screw and is positioned at box top plate top, and the geometric center of the sample hanger 4 in the casing is fixed in the lower end of lifting screw 2, and sample 5 is suspended on the sample hanger.Like this, drive the lifting screw motion by the rotation and lifting disk and just can realize moving up and down of sample hanger and sample.Above tank floor, be provided with dividing plate 8 with holes, well heater 9 and temperature sensor 10 are housed in the space between dividing plate 8 with holes and the tank floor.On dividing plate 8 with holes, lay 6 glass test flumes 7, space mounting above glass test flume 7 has 8 ultraviolet lamp tubes 6, in two separate ranks, up and down four layers arrange, the front and back of two row fluorescent tubes all have living space and hang sample 5, sample 5 hangs on the top of glass test flume 7, hold corrosive medium in each glass test flume 7, water is injected in the bottom of casing 1, and the water surface was not advisable not have the glass test flume.
When sample 5 is immersed in the simulated seawater in the glass test flume 7, be simulated seawater corrosion environment at the incoming tide, and be raised when leaving liquid level when sample 5, be the sunlit at ebb tide corrosion situation of simulated seawater, therefore can reproduce tidal range district material corrosion environment of living in more truly.In addition, because environment temperature is controlled in the casing, so the temperature conditions that can simulate different waters, and experimental result can not help improving the repeatability of experimental result because of room temperature changes.
