Problems solved by technology
[0005] The above scheme can realize the simultaneous completion of the coupon experiments in three areas by relying on a single coupon device, but the above scheme can only measure the corrosiveness of the gas phase, the corrosiveness of the liquid phase and the corrosiveness of the gas-liquid interface in a specific area, which cannot be carried out. buoyancy adjustment, and for the same object, the buoyancy in fresh water and seawater is different, so the above-mentioned hanger device cannot be applied to fresh water and seawater areas at the same time, the applicability is not wide enough, and the flexibility is not strong enough; and the above-mentioned hanger device is also There are disadvantages such as complex structure and weak fixation

Embodiment 2
[0053] This embodiment is similar to Embodiment 1, the difference is that the buoyancy adjustment structure of this embodiment includes an adjustment channel for the user to take or put a buoyancy regulator into the buoy 2, and the regulator here can be foam Boards, place foam boards in the buoyancy cylinder, and then adjust the overall buoyancy by adjusting the number of foam boards.
[0054] Specifically, the buoy 2 here is composed of two semicircles, the aforementioned adjustment channel is obtained when the two semicircles are opened, and the adjustment channel is closed when the semicircles are closed, and the two semicircles are connected to each other by threads.
Embodiment 3
[0056] Such as Figure 4 As shown, the present embodiment is similar to the first embodiment, the difference is that each buoy 2 of the present embodiment has two symmetrically arranged lugs 22, so that the rack can maintain a good balance.

The invention discloses a water test piece hanging rack with an adjustable floating force. The water test piece hanging rack comprises a strip-shaped support and floating cylinders, wherein the floating cylinders are respectively arranged at two ends of the strip-shaped support, a floating force adjustment structure is arranged on at least one of the floating cylinders, a plurality of pieces to betested are sequentially and axially arranged on the strip-shaped support, and the pieces to be tested are fixed on the strip-shaped support by fastening pieces. The floating cylinder is provided withthe floating force adjustment structure, the pieces to be texted can be enabled to be arranged at a target region by adjusting the floating force of the hanging rack, and meanwhile, the water test piece is suitable for experiment of a seawater area and a freshwater area.
Description
technical field [0001] The invention belongs to the technical field of substrate coating corrosion test, in particular to an adjustable buoyancy test piece hanging rack on water. Background technique [0002] At present, coatings, as an effective means of metal or nonmetal corrosion protection, have been widely used in scientific research and engineering fields. The performance evaluation and analysis of coatings mainly include "Visual Colorimetry of Paints and Varnishes" GB / T 9761; "Determination of Film Thickness of Paints and Varnishes" GB / T 13452.2; "Paints and Varnishes Cross-cut test of the film" GB / T 9286;, "Grading method of paint and varnish coating aging" GB / T 1766;, "Measurement method and evaluation of powdering degree of paint coating" GB / T14826;, among them The thickness measurement and scratch test of the paint film are the most representative experimental data, but because they are destructive, the substrate will be damaged to varying degrees.
