Embodiment 1
[0023] A method for preparing a superhydrophobic wire, comprising winding a single wire on a pay-off roller, and sequentially and continuously performing surface pretreatment, sandblasting, chemical etching, surface modification and collection of the single wire through traction. The wire is wound to obtain the finished wire. Specifically, it is divided into the following steps:
[0024] (1) Surface pretreatment: At 40°C, use carbon tetrachloride, absolute ethanol and 0.5mol / L sodium hydroxide solution to ultrasonically clean for 60 minutes at 30 Hz, and then rinse with deionized water for 5 minutes to obtain a single pre-processing wires;
[0025] (2) Sand blasting treatment: perform surface sandblasting treatment on the single pretreated wire obtained in step (1), that is, use a high-speed jet machine to directly spray 250-mesh shot peening onto the surface of the wire to obtain a single microporous wire;
[0026] (3) Chemical etching treatment: immerse the single microporo...
Embodiment 2
[0031] A method for preparing a superhydrophobic wire, comprising winding a single wire on a pay-off roller, and sequentially and continuously performing surface pretreatment, sandblasting, chemical etching, surface modification and collection of the single wire through traction. The wire is wound to obtain the finished wire. Specifically, it is divided into the following steps:
[0032] (1) Surface pretreatment: At 45°C, use carbon tetrachloride, absolute ethanol, and 1mol / L sodium hydroxide solution to ultrasonically clean for 90 minutes at 40 Hz, and then rinse with deionized water for 3 minutes to obtain a single pre-treated surface. handling wires;
[0033] (2) Sandblasting: Sandblasting the surface of the single pretreated wire obtained in step (1), that is, using a high-speed jet machine to directly spray 300-mesh shot peening onto the surface of the wire to obtain a single microporous wire;
[0034] (3) Chemical etching treatment: immerse the single microporous wire o...
Embodiment 3
[0039]A method for preparing a superhydrophobic wire, comprising winding a single wire on a pay-off roller, and sequentially and continuously performing surface pretreatment, sandblasting, chemical etching, surface modification and collection of the single wire through traction. The wire is wound to obtain the finished wire. Specifically, it is divided into the following steps:
[0040] (1) Surface pretreatment: At 43°C, use carbon tetrachloride, absolute ethanol and 0.7mol / L sodium hydroxide solution to ultrasonically clean for 70 minutes at 35 Hz, and then rinse with deionized water for 4 minutes to obtain a single pre-processing wires;
[0041] (2) Sandblasting: Sandblasting the surface of the single pretreated wire obtained in step (1), that is, using a high-speed jet machine to directly spray 300-mesh shot peening onto the surface of the wire to obtain a single microporous wire;
