Example Embodiment

[0038] Example 1

[0039] In this embodiment, a super-hydrophobic copper sheet is prepared by using a metal copper sheet as a substrate, and a novel scale-inhibiting method of bionic super-hydrophobic surface synergistic physical field includes the following steps:

[0040] (1) Take a 5cm×5cm copper sheet for sanding, rinse with ethanol after grinding and dry it for use; after drying, place the polished and rinsed copper sheet in a 1.5mol / L HCl solution at 70°C Etched for 9 min, and rinsed with ethanol after taking out to obtain a super-hydrophilic copper sheet;

[0041] (2) place the super-hydrophilic copper sheet horizontally at 3 cm above the tallow, and then place it in a tube furnace for evaporation. After the evaporation process is completed, the tube furnace is cooled to room temperature and taken out to obtain a bionic super-hydrophobic copper sheet with low adhesion;

Abstract

The invention discloses a novel scale inhibition method of a bionic super-hydrophobic surface cooperating with a physical field, and belongs to the technical field of material scale inhibition. The method comprises the specific steps that firstly, metal copper is etched through etching liquid, then beef tallow is deposited on the copper surface in an evaporation mode to obtain the bionic super-hydrophobic copper surface, finally, the bionic super-hydrophobic copper surface is used for cooperating with a physical field for scale inhibition, and experiments show that the scale inhibition efficiency of cooperation of the bionic super-hydrophobic copper surface and the physical field can reach 100%. The novel scale inhibition method not only has an excellent scale inhibition effect and can greatly reduce the use energy consumption of a physical field, but also has the advantages of being green, free of fluorine-containing pollution, simple in process, low in cost and the like, the bionic super-hydrophobic copper surface has super-hydrophobicity and low adhesion at the same time, the maximum water contact angle can reach 156.1 degrees, and the scale inhibition effect is good. And the catalyst can be effectively applied to corrosion prevention, oil-water separation, self-cleaning and the like.

Description

technical field [0001] The invention relates to a novel scale-inhibiting method with a bionic super-hydrophobic surface synergistic physical field, and belongs to the technical field of material scale-inhibiting. Background technique [0002] Scaling on the surface of materials in industry and life is a common phenomenon. Scaling will have a huge impact on industrial production and life, such as reducing heat transfer efficiency, increasing energy loss, wasting a lot of financial resources, and even causing boilers or pipelines. An explosion occurred, seriously affecting life safety and industrial production. Therefore, it is very important to effectively solve the problem of scaling on the surface of materials. [0003] At present, there are two main methods of scale inhibition: the first is chemical method, and the second is physical method. The chemical method is mainly to treat the aqueous solution by using chemical agents, such as adding scale inhibitors. The chemica...
