And safety, environment is polluted, or even destroy the ecological balance.So how to find a kind of method of simple and effective
These pollutants are handled, carrying out water-oil separating becomes a problem of concern.
Traditional oil-water separation mesh film or oil-water separating net, the effect with water-oil separating, but there is also
Different deficiencies, as manufacturing process is complex, some has used fluorochemical, and some also needs high temperature
Solidification, it is not suitable in a large amount of water containing a small amount of oily separation of oil water mixture etc..
The content of the invention
It is of the prior art to overcome it is an object of the invention to provide a kind of super hydrophilic processing method of copper mesh
Deficiency.
To achieve the above object, the present invention provides following technical scheme：
The embodiment of the present application discloses a kind of super hydrophilic processing method of copper mesh, including step：
(1), copper mesh is cleaned by ultrasonic with acetone and ethanol solution respectively；
(2) copper mesh after cleaning, is immersed into HS (CH2)11Soaked in OH ethanol solutions, on copper mesh surface
Corrosion forms nano-porous structure, then clean with alcohol flushing；
(3), hydroxy thiol is assembled in copper mesh surface modification.
Preferably, in the above-mentioned super hydrophilic processing method of copper mesh, the copper mesh immerses HS (CH2)11OH
Soaked 12~24 hours in ethanol solution.
Preferably, in the above-mentioned super hydrophilic processing method of copper mesh, 40~45 μm of the copper mesh aperture.
