Six tips to prevent moisture
1. Intermittent ventilation method. Close the doors and windows facing south or southeast, that is, the upwind direction, and only open the doors and windows in the downwind direction to reduce the entry of water vapor into the room. When the weather gets nicer, all doors and windows can be opened to speed up the evaporation of water. However, the air humidity outside is at its highest value at noon, so it is not advisable to open windows. Windows should be opened in the afternoon or evening when the climate is relatively dry. 2. Lime moisture absorption method. Lime is a good and simple adsorbent. 1 kilogram of quicklime can absorb about 0.3 kilograms of moisture in the air. Quicklime can be wrapped in cloth or sacks and placed everywhere indoors to keep the indoor air dry. 3． Indoor heating method. Burn a charcoal fire or put a stove in the damp room to increase the indoor temperature so that water vapor cannot condense, thereby reducing indoor humidity. Pay attention to ventilation when doing this, otherwise the consequences will be serious. 4. Air conditioning dehumidification method. Although this move is feasible, it is better to use less in order to save energy. 5. Electrical appliances moisture-proof method. The color TV can always be on standby, and you can also use a hair dryer to blow out the dust and moisture inside the machine through the small holes on the back of the machine. It is best not to place the washing machine in a place with high water vapor density, such as the bathroom, and the position of the washing machine should be elevated; Although the air conditioner has a dehumidifying function, it should be turned on from time to time on humid days to keep it in good condition; computers, in particular, must be moisture-proof. The best way is to turn it on frequently, preferably for an hour every day, to keep it dry. For computers that are not used frequently, you should also open the case and stick a few packages of desiccant from food bags on the inner wall. 6. Use some moisture-proof items to prevent moisture. Such as moisture-absorbing boxes, common hygroscopic products on the market, generally contain calcium chloride particles as the main content, and most of them also add fragrance ingredients. They can integrate dehumidification, fragrance, anti-mold, deodorization and other functions. They are mostly used in wardrobes. , shoe cabinet; moisture-absorbent bag, the principle is similar to the moisture-absorbent box, and is mostly used in sealed spaces. The content is mainly made of absorbent resin. After absorbing water, it becomes jelly-like and is not easy to break into pieces. It can be widely used in clothing, electrical appliances, etc. The moisture absorption effect is better.
■Household Tips
Three Moisture-proof Tips
Intermittent ventilation: The afternoon is the best time. On cloudy and rainy days, close the doors and windows facing south or southeast to prevent ventilation. Reduce water vapor entering the room. At noon, the outside air humidity is at its highest, so it is not advisable to open windows. Instead, windows should be opened in the afternoon or evening when the climate is relatively dry to regulate indoor air.
Lime absorbs moisture: On rainy days, quicklime can be wrapped in cloth or sacks and placed everywhere indoors to keep the indoor air dry.
Air conditioning dehumidification: It is simpler than the first two methods, but now that we are in the power shortage season, it is recommended to use other environmentally friendly and moisture-proof methods to save energy.
■Moisture-proof gadgets
Moisture absorption box
A must-have for wardrobe dehumidification. The more common hygroscopic products on the market generally contain calcium chloride particles as the main content, and most of them also add fragrance ingredients, so they integrate dehumidification, fragrance, anti-mold, deodorization and other functions. Moisture-absorbing boxes are mostly used to absorb moisture in wardrobes and shoe cabinets. Just put it in the cabinet when using it.
Moisture-absorbent bags
Work best in confined spaces. The principle of the hygroscopic bag is similar to that of the hygroscopic box, but the content is mainly made of water-absorbent resin. After absorbing water, it becomes jelly-like and is not easy to break into pieces. The scope of use is also wider. In addition to clothing, you can use it to help dehumidify leather goods, stamps, cameras, pianos, computers, audio and video, etc. If placed in a closed space, the moisture absorption effect is better.
New moisture-proof product
The Japan Forestry Research Institute has developed an environmentally friendly device that effectively dehumidifies: a dehumidifying floor film. This film is made from crab shells and has a thickness of only 30 microns (1 micron is equal to one millionth of a meter). Its characteristic is that it only allows water vapor to pass through. Based on this characteristic, the moisture contained in the floor can be effectively removed by reducing the pressure with a vacuum pump on the other side of the film. If two square meters of this film are used, the humidity of a floor with a thickness of 5 centimeters and an area of ??50 square meters can be kept below 60% to 65%. Generally, if the humidity of the wood can be maintained below 60% to 65%, then the wood does not need to be preservative treated.
The components of the film can be naturally decomposed by microorganisms, so it will not cause environmental pollution even if it is accidentally buried in the soil. In addition, using this film can significantly save energy compared to the traditional method of using air conditioners to lower temperatures and condense moisture in the air.
This kind of dehumidification device can help improve the durability of building materials. Japanese building materials manufacturers and real estate developers plan to market it within five years.
The best and easiest way is to go to the mall and buy a dehumidifier. The humidity in the south in winter is really terrible! Cold to the bone!

Moisture-proof and dehumidification rescue operation
First Aid Methods for Moisture-Stricken Areas
On humid days, if the general home dehumidification method still cannot achieve satisfactory results, you might as well target the most affected corners of your home. Get special care. Due to their different characteristics, different hardest-hit areas have personalized moisture-proof methods.
Hardest hit area: wooden floor
Damage situation: The wooden floor was slippery, and obvious footprints were found when stepping on the wooden floor. Black mold spots were found at the interface between the wooden floor and the base line.
Prevention and treatment methods: Ground moisture is an important reason for wooden floors to become damp, moldy or even rot. The laying of wooden floors is an important part of laying a good moisture-proof foundation. When the wooden floor is laid, it is best to use it for a period of time and then ask a professional to come and wax it. This can evaporate as much moisture as possible during construction and extend the service life of the wooden floor. In addition, Japan has developed a moisture-proof film specifically for wooden floors, which can be laid on the surface of the wooden floor to isolate the contact surface between the wooden floor and the air, so as to better maintain the wooden floor.
Heaviest hit area: wooden furniture
Damage situation: Water droplets formed on the surface of wooden furniture. Even after wiping, water condensation on the surface of wooden furniture could not be alleviated.
Prevention and treatment methods: Nowadays, many wooden furniture have undergone strict drying procedures before leaving the factory, but this does not mean that moisture-proof care cannot be carried out frequently. To deal with water droplets on wooden furniture, you can dip a dry cloth into a special wooden furniture cleaner. This type of cleaner can form a protective film on the surface of the wooden furniture, preventing water vapor from penetrating into the interior of the wooden furniture to a certain extent. In addition, another good way to protect wooden furniture from moisture is to use some absorbent paper or plastic paper on the surface of the wooden furniture.
Hardest hit area: Carpet
Damage situation: Carpet gets dirty easily, and if you look closely, you can see small black hair balls on the surface.
Prevention and treatment methods: Many families lay carpets at the bottom of the coffee table, the end of the bed and other places. These carpets are most susceptible to the influence of the earth's atmosphere when laid on the floor, absorbing moist water vapor. When humid weather comes, you can first lay a piece of soft, absorbent tissue paper in the area where the carpet is laid, and then cover it with the carpet. However, if you are worried about the carpet being seriously affected by moisture, the best way is to put the carpet in a moisture-proof box and use it again when the weather improves.
Heaviest hit area: Home appliances
Damage situation: TVs and computers were found to have blurry images after they were turned on, and it took a few minutes to return to normal.
Prevention and control measures: TVs, computers, audio and other household appliances will become "sluggish in response" in humid weather. An effective way to prevent household appliances from getting damp is to use them at least once a day, energize them, and use the heat generated by the appliances to remove moisture. If the situation is serious, you can use a hair dryer with low-level warm air to dehumidify the appliance externally.
Hardest hit area: fabric furniture
Damage situation: Sitting on the fabric sofa, I felt heavy moisture.
Prevention and treatment methods: It is not easy to judge the moisture condition of fabric furniture from the surface. It is very likely that water vapor has entered the internal space of fabric furniture through the gaps in the fabric. The only way to remove moisture from fabric furniture is through external drying. You can turn on a heater and blow it on the fabric sofa for about half an hour, or use a hair dryer to gently blow the surface of the sofa to alleviate the moisture in the fabric furniture.
How to prevent moisture and dehumidification
There are many methods to prevent moisture and dehumidification, which can effectively improve the overall humid environment of the home. These moisture-proof and dehumidification methods are effortless and suitable for busy people to deal with the humid "back to the south".
Tips 1: Put prevention first
It’s rare that the sun is shining these days, so why not take this opportunity to dry all the “wet” quilts and pillows in your home under the sun? sun? The best way to prevent moisture and dehumidification is to focus on prevention. Generally speaking, home accessories such as quilts, pillows, and fabric sofa covers should be placed in the sun to dry for a few hours after being used continuously for about a month.
Because sunlight is the most environmentally friendly and effective fungicide, it not only makes the quilt fluffy and soft, but also smells full of the warm fragrance of the sun after being exposed to the sun, which is sure to give you a good night's sleep.
Second Tip: Close the windows in the morning and evening
When the humid "back to the south" hits, everyone must remember to close the windows at home, especially the windows facing south and southeast. , not giving any chance to the moisture that is staring at you outside the window to sneak in. The most important periods of moisture-proofing are in the morning and evening every day. The air humidity during these two periods is higher than that at noon. If the doors and windows are not closed in time, water vapor will seriously penetrate into every corner of the home. In addition, if you feel that the closed doors and windows prevent indoor air circulation, it is recommended that you open the windows for a short period of time at noon for ventilation.
Trick three: Instrument method
Moisture-proof and dehumidification can also use technological means to mobilize all dehumidifying appliances in the home to reduce indoor air humidity. Nowadays, most air conditioners used in homes have dehumidification functions. However, the method of using air conditioners to adjust indoor air humidity is slow to take effect, generally taking two to three hours, and will make people indoors feel cold. If you are not satisfied with the dehumidification effect of the air conditioner, you might as well go to the mall to buy a special dehumidifier, which is more effective but consumes more power. In addition, the heaters used by people for heating in winter can also alleviate indoor humidity to a certain extent, but the effective radiation range of the heater is small and cannot achieve an immediate dehumidification effect.
Tip 4: Hang desiccant
Nowadays, there are many desiccants in supermarkets specially designed for moisture-proof and dehumidification. The most common types are moisture absorption boxes and dehumidification bags. Many moisture-absorbing boxes have various scents, such as lemon, lavender, sweet orange, etc., which can make the home full of fragrance. They are suitable for placement in large spaces of daily life such as living rooms, rooms, bathrooms, and kitchens. After using it for a period of time, you can take out the contents of the moisture absorption box, buy bulk desiccant and put it into the box for reuse.
In addition, dehumidification bags made of absorbent resin and charcoal are more suitable for placement in smaller spaces, such as closets, shoe cabinets and other closed spaces where a bag of dehumidification bags can be hung. Drives away moisture. In addition, it is also quite interesting to make your own desiccant. Put an appropriate amount of lime in a small cloth bag, tie it into a small bag and place it in every corner of the room. The lime itself has the effect of absorbing moisture and can also reduce indoor humidity.

Dampproofing
Dampproofing is not only a matter for southerners, northerners’ homes should also be dampproofed. It is rainy in summer and the dampness of the room not only affects the indoor furniture, but also greatly harms the health of the residents and induces colds, rheumatism, asthma and other diseases. Therefore, how to "dehumidify" has become a worry for many people.
Three Tips for Moisture-proofing Your Room
Intermittent ventilation method: On rainy days, close the doors and windows facing the south or southeast (that is, the upwind direction), and only open the doors and windows in the downwind direction to reduce the entry of water vapor. indoor. When the weather clears up, all doors and windows can be opened to speed up the evaporation of water.
Lime moisture absorption method: Lime is an adsorbent. 1 kilogram of quicklime can absorb about 0.3 kilograms of moisture in the air. On rainy days, quicklime can be wrapped in cloth or sacks and placed anywhere in the room to keep the indoor air dry.
Indoor heating method: Burn a pot of charcoal fire and put it on the stove in a damp room (pay attention to ventilation) to increase the indoor temperature, which can prevent water vapor from condensing, thereby reducing indoor humidity.
Moisture-proof tips for household items
Solid wood furniture
Use special cleaning agents for solid wood furniture. The main point of maintenance is to maintain the luster. Apply special furniture cleaner evenly to the surface of the furniture every day, and then wipe it gently.
The fabric sofa
can be dried with a hair dryer. For higher-priced fabric sofas, you need to use a special vacuum cleaner to absorb all the dust on the surface.
In humid weather, gently blow the sofa with a hair dryer to remove moisture from the sofa.
Wrought iron furniture
Repair paint promptly if spots are found. Wrought iron furniture should be wiped regularly with a damp cloth and mild detergent, and attention should be paid to waterproofing and moisture-proofing. If spots appear on the surface as it fades, it should be repaired and painted in time to avoid affecting the overall beauty of the product.
Home appliances
When the humidity in the air is too high, water vapor can easily adhere to the surface and internal parts of electrical appliances. When turning on the computer, due to water vapor, sometimes there will be a hissing discharge sound; even the screen image and audio sound will be blurred. Home appliances should be used frequently in summer to prevent moisture.
Kitchen and bathroom
As long as the materials and workmanship are well grasped, and the corners are properly treated, the possibility of leakage in the kitchen and bathroom will be small, and moisture-proof The problem is solved.
TIPS
★ Make a waterproof layer on the kitchen and bathroom walls. The construction height of the waterproof layer should be no less than 30 cm. If the wall itself is a lightweight wall, the entire wall must be waterproofed.
★Moisture-proof materials are not equal to waterproof materials. The moisture-proof effect is caused by the penetration of moisture-proof agent into the board base material, and the moisture-proof agent has no effect on the waterproof performance of the board itself. Therefore, moisture-proofing only works on moisture in the air.
★You can purchase some practical small moisture-proof items, such as moisture-absorbing boxes and moisture-absorbing bags. The price of these two dehumidifiers is generally around 10 yuan per box/pack.
Removal of Mildew
The weather in summer is sometimes unbearably hot and sometimes heavy rains occur frequently, causing hair to often grow on the walls of the room or clothes, or mildew spots and mildew spots to form. These "hair" and mildew spots are mainly mold. The number of molds in the living environment is closely related to temperature and humidity. Humid summers and rooms where air conditioning is used for a long time without paying attention to ventilation are places where molds like to visit.
Mold is very harmful
Mold infection
A warm and humid environment is conducive to the growth and reproduction of mold, especially when it is originally "out of business" on human skin The mold will "resurgence" and spread in the toes and other parts, causing skin ringworm. If athlete's foot is not treated in time, it can also spread to other parts of the body and become tinea corporis, tinea cruris, tinea manuum, and tinea versicolor. Research shows that mold can also grow and multiply in the human body, causing diseases such as fungal pneumonia.
Respiratory allergy
Inhaling mold can cause respiratory allergy symptoms in people who are sensitive to allergic diseases. In mild cases, they may have symptoms of nasal congestion, runny nose, and sneezing. In severe cases, it may make people have difficulty breathing. , gasping for breath. Molds and their metabolites enter the human body through various channels, and can also cause allergic bronchitis, bronchial asthma, hay fever, dermatitis, etc., or cause the recurrence of original allergic diseases.
Joint pain
Due to the changeable temperature and high humidity in the air, the condition of rheumatoid arthritis and rheumatoid arthritis can easily be aggravated or worsened. It can also cause pain in areas such as back strains, sprains, fractures, surgical incisions and adjacent joints.
Food Poisoning
In a hot and humid environment, food is easily contaminated and becomes moldy. People who eat such moldy food can directly or indirectly cause poisoning and cause symptoms such as diarrhea. Symptoms such as vomiting and diarrhea. Research shows that eating food contaminated with aflatoxin can cause liver cancer, gastric cancer and other diseases.
Cardiovascular and cerebrovascular diseases
In the rainy season, meteorological factors such as air pressure, temperature, and air humidity change greatly, which can easily lead to disorders of the human autonomic nervous system, vasoconstriction, obstruction of blood flow, and blood pressure. When the blood pressure rises, myocardial oxygen consumption increases and the heart load becomes heavier, thereby inducing cardiovascular and cerebrovascular diseases such as myocardial infarction and stroke.
Four tricks to get rid of mold
Research shows that mold is afraid of light, oxygen, cold and dryness. According to these characteristics of mold, relevant anti-mold measures can be taken.
Exposure to the sun. Mold is afraid of sunlight, especially ultraviolet rays in the sun. UV rays can kill or inhibit fungal growth. Therefore, if mold-prone items are placed in the sun, mold cannot survive.
Ventilation. Mold likes warm, moist, and dark environments. According to experiments, mold is most likely to grow and reproduce when the temperature is around 25°C and the relative air humidity is 70%. Therefore, opening windows frequently to maintain indoor air circulation can reduce the number of indoor molds.
Dry.
Studies have found that people who live in dark and humid rooms have a higher incidence of allergic asthma. Keeping the surrounding environment dry can evaporate the moisture on the surface of mold-prone objects, and the indoor humidity will also be reduced, causing mold to lack the necessary moisture for growth and reproduction.
Cool down. According to research, mold cannot reproduce below 5°C. Therefore, keeping food in the refrigerator or freezer can prevent mildew.
Special reminder
★Inhalation of mold-contaminated food through the respiratory tract and ingestion of mold-contaminated food are the main ways for people to come into contact with mold and its metabolites. Therefore, moldy food must be disposed of in time and must not be edible.
★Some molds are toxic, such as Fusarium, which are found in moldy grains. Some fungi can produce toxins, such as Aspergillus aflatoxin. No matter what kind of fungus-contaminated food is ingested, it can cause acute or chronic food poisoning. (
