Problems solved by technology

At present, the evaluation of the antifouling performance of antifouling materials mainly adopts the shallow sea hanging plate test (GB / T5370-2007) and the dynamic test method of antifouling performance of ship antifouling paint (GB / T7789-2007). The number and coverage area of ​​fouling organisms are analyzed. This method has the disadvantages of long cycle time and large consumption of raw materials.
In terms of bio-adhesion testing of marine fouling, in 2009, Dalian Fisheries Institute researched and established a "rotary hub" type adhesion testing device. Movement, by changing the flow rate of water to evaluate the adhesion of fouling organisms, this method has the disadvantages of low test accuracy, low degree of automation, and difficulty in meeting the needs of continuously developing research on antifouling materials.

Embodiment 1

[0011] In the present embodiment, the settling chamber 22 of the box structure is provided with water inlet 1, perforated stainless steel plate 2, honeycomb polycarbonate plate 3, stainless steel sieve plate 4, and exhaust valve 5 in order from right to left. The left end of the sedimentation chamber 22 is provided with a test chamber 7 transversely, a differential pressure transmitter 6 is provided on the left side of the test chamber 7, a vacuum pump 8 is installed in the test chamber 7, and a water tank 10 and a water tank 10 are provided at the left end of the test chamber 7 A light source 9 is made at the top of the tank 10, and the pipeline from the bottom of the water tank 10 is connected to the water inlet 1 through a multi-end valve control. The connected pipelines are respectively made with a variable frequency pump 11, a flow meter 12 and a pressure transmitter 13; a programmable controller 20 , The computer 21 communicates with the differential pressure transmitter 6...

Embodiment 2

[0013] In this embodiment, the sample to be tested is fixed on the sample mounting table 15, the vacuum pump 8 is turned on, and the vacuum is drawn to fix the sample to be tested on the stage 14, and then the sample mounting table 15 is mounted on the test chamber 7 and passed the height The regulator 19 adjusts the height of the sample so that the surface of the sample to be tested is level with the lower surface of the test chamber 7; when the exhaust valve 5 is opened, seawater enters the sedimentation chamber 22 from the water inlet 1, and then passes through the perforated stainless steel plate 2 in a honeycomb shape. Carbonate plate 3, 24 mesh stainless steel sieve plate 4, after sea water is filled with the whole device, and after observing that there are no bubbles in the test chamber 7, close the exhaust valve 5; increase the sea water flow rate and test the adhesion of the fouling organisms on the surface of the material.

Embodiment 3

[0015] In this example, Ulva pertusa Kjellm (Ulva pertusa Kjellm) was collected from the sea area, washed repeatedly with seawater, brought back to the laboratory at low temperature, and rinsed with filtered and disinfected seawater for 4-5 times to remove protozoa and epiphytes; The algae body was stored under constant conditions of temperature 4℃ and photoperiod 12L:12D for later use. Several strains were selected and placed in a Erlenmeyer flask containing sterilized seawater for aerated culture at a water temperature of 15℃ and continuous light for 15 hours. Collect the spores of Ulva vulgare; dilute the collected spores of Ulva vulgaris with f / 2 nutrient solution to a concentration of 1×10 5 Each / L, shake well for use; place the self-made experimental samples A, B, C, D, E obliquely into a 250ml beaker containing 200ml experimental spore solution, at 20℃, light intensity about 7000Lx, light to dark ratio 12 :Incubate for 24 hours under the condition of 12; after 24 hours, t...
