Embodiment 1

[0037] 1. Test conditions and test process:

[0038] 1.1. The real sea test is a natural environment, and the sample speed is controlled at 8-50 knots. At the same time, the real sea environment is monitored, such as seawater salinity, pH value, water temperature, etc.

[0039] 1.2. The actual sea test needs to make the surface of the sample reach a turbulent state, and the stop ratio is 1:30 to 30:1. Set the test rotation and rest time; according to the actual situation, it is also possible not to set the stop ratio .

[0040] 1.3. During the test, the torque of the sample can be monitored in real time or periodically, and the surface roughness of the coating can be measured.

[0041] 1.4. Process the test data, draw the working curve, and evaluate the resistance performance of the antifouling paint.

[0042] 1.5. In this embodiment, PVC is used as the sample substrate, and the cylindrical sample has a diameter of 200 mm and a height of 200 mm. Before coating the antifouli...

Abstract

The invention relates to a test method for testing the resistance performance of an antifouling coating in a real sea environment. The method includes the following steps that: a cylindrical sample isprepared, and antifouling paint is applied to the treated cylindrical sample until the thickness of the antifouling paint achieves a target coating thickness; the cylindrical sample is soaked into areal sea for d1 days through the buoyant raft of a ship or a real sea resistance performance simulation test device under a condition that a navigation-immobilization ratio ranges from 1:30 to 30:1 and a condition that a speed ranges from 8 to 5 Knots, so that fouling organisms or slime can be attached to the surface of the sample, torque and surface roughness testing is performed on the socked sample; the sample is driven to rotate in seawater by the real sea resistance performance simulation test device at a speed from 8 to 50 Knots, and a turbulent state is generated on the surface of the sample; and the sample is made to rotate in the real sea for d2 days, the sum of d1 and d2 is a test period, after the sample rotates, torque and surface roughness testing is performed on the sample. With the test method of the invention adopted, the state and resistance performance change of the ship in sailing can be simulated realistically; and the comprehensive performance and effect of the resistance of the coating are evaluated by means of monitoring the change of roughness.

Description

technical field [0001] The invention relates to the technical field of test methods, in particular to a test method for the resistance performance of an antifouling coating in a real sea environment. Background technique [0002] The performance of antifouling paint directly affects the sailing resistance of ships, and sailing resistance is one of the research hotspots in the world in recent years. How to set up a simple and efficient test method to evaluate the resistance performance change of antifouling paint during ship navigation is very important. [0003] At present, the inspection and evaluation methods of the resistance performance of antifouling paints in the world mainly rely on real ships. By installing an energy efficiency acquisition system on a real ship, the actual navigation energy efficiency data of the ship is accumulated, and evaluated through a series of complex data processing and analysis. However, the actual ship test is expensive, the test period i...
