Description
Technical Field

Background
Separation processes play an important role in industrial production, mainly in relation to gas phase separation, liquid phase separation and multi-phase separation. Currently, separation processes are mainly achieved by distillation or adsorption units. Such processes typically consume large amounts of energy and have large footprint, high maintenance and operating costs, and low efficiency. The supply and demand proportion of industrial production and chemical products is severely limited. Therefore, under the social background of rapid development of industrialization, a method for replacing the traditional separation means needs to be solved urgently.
At present, the membrane separation technology has the advantages of flexible operation, small occupied area, large operable area, low energy consumption, high separation efficiency, no phase change or chemical change in the operation process and the like, and becomes the most promising alternative separation technology at present. The technology is a process of selectively separating and purifying a system to be separated by using membrane materials with channels or mass transfer holes with different sizes under the condition of concentration gradient or external driving force.
Currently, the film materials are mainly classified into organic films and inorganic films, and the organic films are most widely applied in the field of commercialization due to the advantage of low price, but the corrosion resistance of the materials is poor. Compared with the inorganic film, the inorganic film has better corrosion resistance, but the cost is higher, and the preparation process is not comparable to an organic film system which can be continuously prepared. The currently emerging two-dimensional membranes have a nanoscale thickness, a centimeter-scale size and excellent separation efficiency, and are gradually exposed in the industrialized process. At present, the preparation method of the two-dimensional membrane mainly adopts vacuum-assisted suction filtration, and the requirement of large-scale continuous industrial preparation is severely limited.

Example 2
A two-dimensional film continuous production process based on an electrophoresis strategy,
the apparatus of example 1 was used, comprising the following steps:
step 1, connecting all reels with electrodes, fixedly connecting and convoluting a stainless steel mesh (2500 meshes) porous substrate with the average pore diameter of 0.25 mu m and the thickness of 2 mu m on a first reel 1-1 through conductive adhesive, and enabling the porous substrate to pass through an electrodeposition tank 3 and a dryer 5 through a second reel 1-2, a third reel 1-3 and a fourth reel 1-4; the overlapping size of the adjacently deposited porous substrates is controlled to be within 0.5 cm. The conductive paste is used to connect the substrates to each other to facilitate uniform deposition of the two-dimensional film on the substrates during the electro-deposition process.
And 3, setting the temperature of the dryer to 80 ℃, and ensuring that the film can be completely dried at the current reel rotating speed.
And 4, collecting the dried film by a 1-4 reel to obtain the final two-dimensional film coiled material.
Compared with the traditional suction filtration, the electrodeposition can quickly form a film within 2min to reach the same thickness of the film obtained by the suction filtration method, and the time for frequently replacing the substrate material is saved after the electrodeposition is combined with a roll-to-roll process, so that the time can be saved by more than 60 percent compared with the film formed by single electrodeposition.
