Abstract
The invention discloses an experimental apparatus for simulating a corrosion environment in a tide range region in the ocean environment. A main body of the apparatus is a test box body. A top panel of the box body is provided with a lifting device. A test sample hanger, ultraviolet lamp tubes and corrosion medium testing tanks are arranged in the box body. The bottom of the test box body is provided with a clapboard with holes. The testing tanks for containing corrosion mediums are arranged on the clapboard with the holes. Seawater or other corrosion mediums are contained in the corrosion medium testing tanks. A heater and a temperature sensor are arranged in a space between the clapboard with the holes and the bottom surface of the box body. Clear water is filled in a testing box to carry out water bath temperature control; when test samples are all soaked in the corrosion mediums, the corrosion environment in the tide rising process of the ocean is simulated; and when the test samples are lifted up to leave from the liquid levels and are irradiated by ultraviolet light, the corrosion environment irradiated by the sunlight in the tide ebbing process of the ocean is simulated. Therefore, according to the experimental apparatus, the influence of alternation of wetting and drying of the seawater and the sunlight irradiation is comprehensively considered, the simulated corrosion environment is closer to the actual corrosion environment, and the experimental foundation is provided for researching a tide range region corrosion protection technology.
Description
Technical field:
The present invention relates to a kind of marine corrosion simulated experimental provision, especially simulate the corrosion testing apparatus of tidal range district, ocean environment.
Background technology:
The tidal range district in the ocean is coated with organic coating and is the steel construction process for protecting surface that the most often adopts, and the useful life of organic coating mainly receives 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 have the Considering Coupling Effect dry wet alternating environment.So far do not see special report as yet to the corrosion simulated test unit in tidal range district.
Summary of the invention:
Technical matters to be solved by this invention 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 solution adopted for the present invention to solve the technical problems is, the height through 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 through 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, drives the lifting screw motion through 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 invention has the beneficial effects as follows; 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 through rotating the up-down disk; Thereby the control soak time of sample in corrosive medium and the irradiation time of ultraviolet light have been simulated seawater alternation of wetting and drying and dried sunlit environment of stage in the oceanic tide difference ring border, thereby for studying tidal range district's corrosion protection technology and corrosion failure mechanism experiment basis are provided.
Description of drawings:
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1 is the structural front view according to tidal range district, ocean corrosion simulated experiment device proposed by the invention.
Fig. 2 is the structure vertical view of experimental provision shown in Figure 1.
Among the figure, 1. test casing, 2. lifting screw, 3. up-down 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, and 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 through 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 through 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 the suspension 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, the temperature conditions that therefore can simulate different waters, and also experimental result can not help improving the repeatability of experimental result because of room temperature changes.
