The alkali return and moisture return of the wall are related to the atmospheric temperature and humidity.
The alkalinity of the back wall mainly occurs in late winter, early spring and late autumn. For these stations, temperature usually increases or decreases precipitation, resulting in a decrease in the amount of air in water vapor, which leads to the migration of water from the floor to the wall. Then the body evaporated on the wall. In this process, the salt in the water vapor will crystallize in the wall.
The alkali return and moisture return of the wall are related to light.
The alkalinity of the wall is also related to the illumination. Usually, in the case of sufficient light, the south exterior wall is sensitive to alkali resistance, while the north side is not easy to return to alkali.
The alkali return and moisture return of the wall are related to ventilation.
Generally speaking, the eutrophication of the inner wall makes the outer wall serious, while the outer wall is not well ventilated and the water vapor is not easy to gather, which makes the possibility of alkali returning to the wall very small.
The wall of the kitchen and bathroom is wet with water every day, which is the reason. This is a common reason for the resurrection of the wall. This is especially true for kitchen cabinets and bathroom cabinets. This is because water often spills along the wall of the kitchen cabinet when washing vegetables and dishes. It is suggested to fill cabinets and bathroom cabinets and use plastic glass walls to prevent water from disappearing between the walls.
The waterproof layer of the external wall is damaged.
The waterproof layer of the external wall of the building was damaged, which led to water infiltration into the building. If this is the reason why the wall recovered from the tide, you must contact the hotel or developer to completely correct the appearance of the building. The exterior of the building is leaking, especially after rain and snow. This is a big problem that the owners can't solve by themselves.
This wall doesn't work.
If the wall is not well insulated, the temperature difference between inside and outside will be great. In this way, the moisture in the indoor air will condense on the wall after cooling, making the wall wet. You can exclude it by performing a compression test. If the inhibition test fails, there is a leak somewhere in the pipeline.
The above is the introduction of the wall returning to alkali and moisture, I hope it will help you.
