What does it mean to go back to Nantian

Every year from March to April, friends in southern China often see such a scene at home-the floor and walls are like "sweating", and many small drops of water are attached. If the tile floor is not careful, you will have to fall down, look upset and walk flustered. This phenomenon is called "Returning to Nantian" among the people in South China.

How did Huannantian come into being?

Huannantian is a weather resurgence phenomenon, which generally appears in February and March in spring. The main reason is that after the cold air leaves, the warm and humid airflow quickly counterattacks, resulting in the temperature rising and the air humidity increasing, and some cold objects are prone to produce water droplets when they encounter the warm and humid airflow. The phenomenon of returning to the south sky is more serious in the south, which is related to the fact that the south is close to the sea and the air is humid. When "Returning to the South Sky" appeared, the air humidity was close to saturation, and the walls and even the ground would be "bubbling with water". There were wet scenes everywhere, and the air seemed to be able to wring out water. The dense fog is the most distinctive appearance of "returning to the south sky". There are omens before the arrival of "returning to the south sky": first, there must be a continuous cold process, at least for more than three days, in order to make the temperature of indoor objects drop to the same level as that of outdoor, that is, the so-called "freezing". At this time, the weather changed suddenly, the warm and humid airflow in the south strengthened, and the outdoor temperature rose rapidly (the air dew point also rose rapidly). At this time, although the indoor object temperature also rose, it could not catch up with the outdoor temperature rising speed, and the indoor and outdoor temperature difference widened, which led to the indoor object temperature being lower than the air dew point, resulting in the phenomenon of "returning to the south".

moisture-proof strategy for returning to Nantian

moisture-proof cheats for rooms

Method 1: spread newspapers. Avoid opening doors and windows, and spread newspapers on the ground and tables to absorb moisture.

method 2: light candles. Lighting candles can prevent water vapor from condensing, thus reducing indoor humidity. If there is a musty smell at home, you can choose a candle containing natural plant essential oil, which can not only dry the air, but also remove the musty smell in the room.

method 3: mop the floor with hot water and salt. This method can accelerate the evaporation of water. After mopping the floor, put some waste cartons or newspapers on the doorstep to reduce the moisture brought in by the soles.

method 4: use equipment. Use dehumidifier, air conditioner or heater. At present, the dehumidification products on the market mainly include air conditioners, dehumidifiers and heaters, and the air conditioners used in general households all have dehumidification function.

method 5: blow the north wind. Open the doors and windows when the north wind turns. More than 8% of the returning days disappeared due to the cold air heading south. If the weather forecast says that there is cold air going south and the local wind direction turns to the north, you can safely open the doors and windows for ventilation.

method 6: lime absorbs moisture. In small space areas such as toilets and bathrooms, quicklime can be wrapped in cloth bags to absorb moisture. You can also poke holes in the bag of washing powder to absorb moisture with washing powder.

moisture-proof tips for clothes

Method 1: Use activated carbon. Don't arrange clothes in rainy days to avoid moisture invading the wardrobe; Go to the supermarket to buy absorbent boxes, activated carbon, etc. and put them in the closet, and remember to close the closet door.

method 2: heat water to dry clothes. Before using the washing machine to spin-dry clothes, add some hot water to the spin-dry bucket, which will help the evaporation of clothes moisture, but it should be noted that the temperature of hot water should not be too high.

method 3: use green tea, absorbent bags, etc. The moisture-absorbing bag has little effect on a large area of moisture-proof, but it can still play a certain role in moisture-proof when placed in the wardrobe. You can also buy some cheap green tea and put it in the wardrobe, which can absorb moisture and deodorize it.

Moisture-proof tips for furniture

For families undergoing renovation, you can put some charcoal and camphor wood blocks under the paved floor. Charcoal has the function of moisture absorption, which can keep the floor dry and not easy to deform, while camphor wood has the function of anti-moth. Putting some camphor wood in a proper amount can effectively prevent the floor from being eaten by insects.

solid wood furniture: to be maintained with a special cleaner, you can apply protective wax or a special cleaner evenly on the surface of the furniture, and then gently wipe it to keep it shiny and moisture-proof; If the edge of wood-based panel furniture is not well sealed or is damp, it is easy to absorb water, which will cause the furniture board to expand and be damaged. When using it, pay attention to waterproofing, install waterproof pads under the furniture legs that are easy to absorb water, and keep a good ventilation distance near the exterior wall and bathroom walls.

Fabric sofa: To clean the dust on its surface with a special vacuum cleaner, it is best to use a sofa towel with good water absorption and clean it frequently.

metal and wrought iron furniture: it should be scrubbed with oilcloth and mild detergent. If spots appear in wrought iron furniture, it should be repaired and painted in time. If dew is found on the surface, it should be wiped with dry cloth in time to prevent corrosion.

rattan furniture: it is easy to mold and breed mold between the gaps of rattan, so it should be cleaned and ventilated frequently, but don't expose to the sun after cleaning to prevent it from deformation or fracture; In addition, there is a good way to damp-proof wooden furniture, that is, stick some absorbent paper or plastic paper on the surface of wooden furniture. For leather sofas, you can put some desiccant to keep dry.

moisture-proof tips for home appliances

put home appliances in a ventilated place to increase the frequency of using electrical appliances, because the machine will generate heat when it is running, which can effectively disperse moisture. When home appliances such as TV or computer are not in use, it is best to put on a protective cover. At the same time, it is necessary to improve the utilization rate of household appliances, preferably once a day, and use the heat generated when household appliances are electrified to disperse moisture.

natural dehumidifier in the kitchen

baking soda powder: readily available baking soda powder in the kitchen can absorb moisture, and after caking, it can be used as a cleaning agent to scrub bathtubs, sinks, washbasins, etc., to remove oil, remove dirt and prevent mildew, with good effect.

Precautions

Don't open the south window when it is sunny at noon. It is necessary to close the doors and windows in advance, and prevent them from entering the outdoor warm and humid air flow. Some people think that it is sunny at noon and they can open the window for ventilation, which can not alleviate the humidity phenomenon. At noon, the outdoor temperature is the highest, and the temperature difference between indoor and outdoor is also the largest. Ventilation at this time sometimes leads to more serious condensation of water vapor on indoor floors and walls.

keep the bathroom door handy to prevent water vapor from spreading to other parts of the room. After cooking or taking a shower, remember to take the kitchen door and toilet door, and turn on the exhaust fan to reduce the water entering the living room.
