As long as the system remains open, the water moves in the wet direction all the time, and does not flow back to enter the inside of the structure again.
However, in practical application, the water content in the concrete structure is not as low as possible, and if the water content of the concrete structure is too low, dehydration and cracking of the concrete structure may be caused; and the situation of the structure as the object to be dehumidified is different from place to place, and therefore cannot be considered in a lump. The discharged free water does not flow to the same position, but moves to the positions of the plurality of negative electrodes, and only water is actually removed, but the discharged free water cannot be collected.
As shown in fig. 1, fig. 1 is a top view of a room, but the moisture content of the respective interiors of the four walls of the room is not the same, and two phenomena may occur when electro-osmosis technology is applied to the room. One is that free water in the pores and surfaces of the wall does not collect after exiting the wall. Secondly, the water content inside the four walls is different, and under the condition that the water content inside the four walls is different greatly, the same pulse current output to the four walls can cause excessive water loss of some walls or cause the electroosmosis effect of some walls to be not obvious enough.
