[0012] A method for testing the super-hydrophobic anti-fouling and anti-icing performance based on DSAN comprises the following steps:

[0013] S1: Open the test door, place three test plates coated with DSAN material on the hollow placement plates of the superhydrophobic performance test chamber, the anti-icing performance test chamber, and the anti-fouling performance test chamber, respectively, and close the test door;

[0014] S2: Open the switch valves on the three connecting pipes respectively, start the air pump through the touch control screen, and the air pump sucks air to create a negative pressure environment in the three hollow placement plates through the three connecting pipes, so that the multiple suction cups of the three hollow placement plates can firmly adsorb the corresponding test plates coated with DSAN material;

[0015] S3: Pull out the pipe plug, add a certain amount of deionized water into the upper water storage shell through the water adding pipe, and cover the pipe plug after the water adding is completed;

[0016] S4: The upper water pump is started by controlling the touch control screen. The upper water pump draws the deionized water in the upper water storage shell into the upper spray pipe through the upper water suction pipe. The deionized water in the upper spray pipe is sprayed onto the test board coated with the DSAN material in the super-hydrophobic performance test chamber through the upper spray head. The liquid droplets on the test board are waited for to reach static equilibrium. The test board is photographed by controlling multiple imagers through the touch control screen.

[0017] S5: The deionized water in the super-hydrophobic performance test chamber flows into the middle water storage shell through the upper inclined water tank and the upper return pipe;

[0018] S6: The electronic scale weighs the weight G0 of the dry test board coated with the DSAN material in the anti-icing performance test chamber, and feeds back the weight data to the touch control screen.

The refrigerator is controlled to cool by the touch control screen. When the cooling time is up, the refrigerator is controlled to be turned off by the touch control screen. The electronic scale weighs the weight G1 of the test board with ice coating, and feeds back the weight data to the touch control screen.

The displacement sensor is controlled to work again through the touch control screen, and the static equilibrium line roughness R1 of the test plate surface is recorded, and the data is fed back to the touch control screen. Then, the touch control screen calculates the roughness change R2 of the test plate as R1-R0, and the anti-fouling property of the DSAN material can be evaluated by the roughness change.

5. A method for testing super-hydrophobic anti-fouling and anti-icing performance based on DSAN, characterized in that: The following steps are involved: S1: Open the test door (2) of the test device, place three test plates (14) coated with DSAN material on the hollow placement plates (13) of the superhydrophobic performance test chamber (8), the anti-icing performance test chamber (10), and the anti-fouling performance test chamber (11), respectively, and close the test door (2); S2: opening the switch valves (17) on the three connecting pipes (18) respectively, and starting the air pump (15) through the touch control screen (4), so that the air pump (15) draws air through the three connecting pipes (18) to create a negative pressure environment in the three hollow placement plates (13), so that the multiple suction cups (28) of the three hollow placement plates (13) can firmly adsorb the corresponding test plates (14) coated with the DSAN material; S3: Pull out the pipe plug (21), add a certain amount of deionized water into the upper water storage shell (23) through the water adding pipe (22), and cover the pipe plug (21) after the water adding is completed; S4: The upper water pump (20) is started by controlling the touch control screen (4), and the upper water pump (20) draws deionized water in the upper water storage shell (23) into the upper spray pipe (7) through the upper water suction pipe (19). The deionized water in the upper spray pipe (7) is sprayed onto the test plate (14) coated with the DSAN material in the super-hydrophobic performance test chamber (8) through the upper spray head (6), and the liquid droplets on the test plate (14) are waited to reach static equilibrium. The test plate (14) is photographed by controlling the touch control screen (4), and the multiple imagers (27) transmit the photographed pictures to the touch control screen (4). The test personnel establish a liquid droplet model through the touch control screen (4), read the bottom surface area and volume of the liquid droplet, and obtain the absolute contact area and residual absolute volume of the liquid droplet to evaluate the hydrophobicity of the DSAN material; S5: the deionized water in the super-hydrophobic performance test chamber (8) flows into the middle water storage housing (23) through the upper inclined water tank (12) and the upper return pipe (24); S6: The electronic scale (30) weighs the weight G0 of the test plate (14) coated with the DSAN material and dried in the anti-icing performance test chamber (10), and feeds back the weight data to the touch control screen (4). The touch control screen (4) controls the start of the intermediate water pump (20). The intermediate water pump (20) draws the deionized water in the intermediate water storage shell (23) into the intermediate spray pipe (7) through the intermediate water suction pipe (19). The deionized water in the intermediate spray pipe (7) is sprayed into the anti-icing performance test chamber through the intermediate spray head (6). On the test plate (14) coated with the DSAN material in (10), the refrigerator (29) is controlled to cool by the touch control screen (4). When the cooling time is up, the refrigerator (29) is controlled to be turned off by the touch control screen (4). The electronic scale (30) weighs the weight G1 of the test plate (14) with ice coating, and feeds the weight data back to the touch control screen (4). The touch control screen (4) calculates the weight change G2 of the test plate (14) as G1-G0, and the anti-icing property of the DSAN material can be evaluated by the weight change. S7: the deionized water in the anti-icing performance test chamber (10) flows into the lower water storage shell (23) through the middle inclined water tank (12) and the middle return pipe (24), and sewage is added to the deionized water in the lower water storage shell (23) through the sewage adding pipe (25) to obtain mixed water; S8: Control the drive motor (5) to move forward and reverse through the touch control screen (4), and the drive motor (5) drives the screw rod (31) to move forward and reverse. During the forward and reverse movement of the screw rod (31), the moving block (32) moves back and forth on the screw rod (31), and the moving block (32) drives the displacement sensor (33) to move back and forth. During the reciprocating movement of the displacement sensor (33), the initial line roughness RO of the surface of the test plate (14) coated with the DSAN material in the antifouling performance test chamber (11) is recorded, and the data is fed back to the touch control screen (4). After the data feedback is completed, the drive motor (5) is turned off through the touch control screen (4), and the lower water pump (20) is started through the touch control screen (4). The lower water pump (20) is turned on. 0) The mixed water in the lower water storage shell (23) is pumped into the lower spray pipe (7) through the lower water suction pipe (19), and the mixed water in the lower spray pipe (7) is sprayed onto the test plate (14) coated with the DSAN material in the antifouling performance test chamber (11) through the lower spray head (6), and the liquid droplets on the test plate (14) are waited to reach static equilibrium, and the displacement sensor (33) is controlled to work again through the touch control screen (4), and the static equilibrium line roughness R1 of the surface of the test plate (14) is recorded, and the data is fed back to the touch control screen (4), then the touch control screen (4) calculates the roughness change R2 of the test plate (14) as R1-R0, and the antifouling property of the DSAN material can be evaluated by the roughness change; S9: The mixed water in the anti-fouling performance test chamber (11) is discharged through the inclined water tank (12) below and the sewage pipe (26), and the test is completed.
