My home is a little humid, and there are many tide insects and small flying insects in summer. What should I do?

1. intermittent ventilation. South or southeast? That is, close the doors and windows in the windward direction, and only open the doors and windows in the downwind direction to reduce the water vapor entering the room. When the weather turns fine, all doors and windows can be opened to accelerate the evaporation of water. However, the outdoor air humidity is at the highest value at noon, so it is not suitable to open the window. It should be adjusted in the afternoon or at night when the climate is dry. 2. Lime moisture absorption method. Lime is a good and simple adsorbent. 1 kg quicklime can absorb about 0.3 kg of water in the air. It can be wrapped in cloth or sacks and placed in various places indoors to keep the indoor air dry. 3. Indoor heating mode. Burn a pot of charcoal fire or put a stove in a humid room to raise the indoor temperature, so that the water vapor cannot condense, thus reducing the indoor humidity. Pay attention to ventilation, otherwise the consequences will be serious. 4. Air conditioning pumping method. Although this move is feasible, in order to save energy, it is better to use less. 5. Electrical moisture-proof method. Color TV can always be in standby state, or you can use a hair dryer to blow out dust and moisture from the machine through the small hole at the back of the machine. It is best not to put the washing machine in places with high water vapor density such as toilets, but also to raise the position of the washing machine; Although the air conditioner has dehumidification function, it should not be turned on regularly in rainy days to keep it in good condition; Especially computers should be moisture-proof. The best way is to turn it on frequently, preferably for an hour every day to keep it dry. Computers that are not often used should also be opened and desiccant should be attached to several food bags on the inner wall. 6. You can use some moisture-proof objects to prevent moisture. For example, water-absorbing boxes, common water-absorbing products on the market, generally take calcium chloride particles as the main component, and most of them also add essence components, which can integrate dehumidification, fragrance, mildew prevention, deodorization and other functions, and are mostly used in wardrobes and shoe cabinets; The principle of moisture-absorbing bag is similar to that of moisture-absorbing box, and it is mostly used to seal the space. The content is mainly water-absorbing resin, which becomes jelly-like after water absorption and is not easy to disperse into powder. Can be widely used for moisture absorption of clothes, electrical appliances and the like, and has good effect.

Moisture-proof triaxial

Intermittent ventilation: afternoon is the best time. Close the doors and windows facing south or southeast in rainy days to reduce water vapor entering the room. At noon, the outdoor air humidity is at the highest value, so it is not suitable to open the window. In the afternoon or evening, when the climate is dry, open the window to adjust the indoor air.

Lime absorbs moisture: In rainy days, you can wrap quicklime with cloth or sack and put it indoors to keep the indoor air dry.

Air conditioning dehumidification: simpler than the first two methods, but now it is in the season of power shortage, so it is recommended to use other environmental protection and moisture-proof methods to save energy.

■ Moisture-proof gadgets

Moisture absorption box

It is necessary to dehumidify the wardrobe. Generally, the common absorbent products on the market are mainly composed of calcium chloride particles, and most of them are added with essence, so they have the functions of dehumidification, fragrance, mildew prevention and deodorization. Moisture absorption boxes are mostly used for moisture absorption in wardrobes and shoe cabinets. When you use it, just put it in the cupboard.

Moisture absorption packaging

Confined space works best. The principle of water-absorbing bag is similar to that of water-absorbing box, but the contents are mainly water-absorbing resin, which becomes jelly-like after absorbing water and cannot be easily broken into pieces. It has a wider range of applications. Besides clothes, leather goods, stamps, cameras, pianos, computers, audio-visual equipment, etc. Can seek its help in dehumidification. If placed in a closed space, the moisture absorption effect is better.

Moisture-proof new products

Japan Forest Research Institute has developed an effective dehumidifying and environmental protection device: dehumidifying floor film. This film made of crab shells is only 30 microns thick (1 micron is equal to 1 millionth of a meter), which is characterized by allowing only water vapor to pass through. According to this characteristic, the moisture contained in the floor can be effectively removed by decompressing the other side of the film with a vacuum pump. If two square meters of this film is used, the humidity of the floor with a thickness of 5 cm and an area of 50 square meters can be kept below 60% to 65%. Generally, if the humidity of wood can be kept below 60% to 65%, then wood does not need to be preserved.

The composition of the film can be naturally decomposed by microorganisms, so even if it is buried in soil by mistake, it will not cause environmental pollution. In addition, compared with the traditional method of using air conditioner to reduce the temperature and condense the moisture in the air, using this film can greatly save energy. This dehumidifier is conducive to improving the durability of building materials, and Japanese building materials manufacturers and real estate developers plan to put it on the market within five years.

The best and easiest way is to go to the mall to buy a dehumidifier. The humidity in winter in the south is really terrible! It's freezing!

Moisture-proof and dehumidification rescue operation

First-aid methods in moisture-proof disaster areas

In wet days, if the general household dehumidification method still can't achieve satisfactory results, we may wish to carry out special care according to the seriously affected corners of the home. Due to their own characteristics, different disaster areas have personalized moisture-proof methods.

Hardest hit area: wooden floor

Disaster situation: the wooden floor is slippery, and there are obvious footprints when stepping on it. Black mildew was found at the junction of wooden floor and footstone.

Prevention and cure: The damp ground is an important reason why the wooden floor is damp, moldy and even rotten. The laying of wooden floor is an important link to lay a good foundation for moisture prevention. After the wooden floor is laid, it is best to use it for a period of time, and then ask professionals to wax it. In this way, the residual moisture in the construction can be volatilized as much as possible, and the service life of the wood floor can be prolonged. In addition, Japan has also developed a kind of moisture-proof film specially for wood floors, which can be spread on the surface of wood floors to isolate the contact surface between wood floors and air, so as to better maintain wood floors.

The hardest hit area: wooden furniture

Disaster situation: water droplets are formed on the surface of wooden furniture, and the condensation on the surface of wooden furniture cannot be alleviated after wiping.

Prevention: Now many wooden furniture have gone through strict drying procedures before leaving the factory, but this does not mean that moisture-proof care cannot be carried out frequently. To deal with the water drops on wooden furniture, dry cloth can be soaked in special cleaning agent for wooden furniture, and a protective film can be formed on the surface of wooden furniture to prevent water vapor from infiltrating into the interior of wooden furniture to some extent. 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.

The hardest hit is the carpet.

Disaster situation: the carpet is easy to get dirty, and careful observation shows that the surface is covered with small black balls.

Prevention and control measures: Many families lay carpets at the bottom of the coffee table and at the end of the bed. When these carpets are laid on the floor, they are most vulnerable to the influence of the earth's atmosphere and absorb moisture vapor. When wet weather comes, you can first lay a soft and absorbent tissue skin on the carpeted area, and then cover it with carpet. However, if you are worried about the carpet getting seriously wet, the best way is to store the carpet in moistureproof box until the weather improves.

The hardest hit area: home appliances

Disaster situation: after the TV and computer are turned on, the picture is blurred and returns to normal after a few minutes.

Prevention: TV sets, computers, stereos and other household appliances will be "slow to respond" in wet weather. The effective way to prevent household appliances from getting damp is to use them at least once a day, electrify the appliances, and achieve the purpose of eliminating damp through the heat generated by the fuselage. If the situation is serious, you can use the low-grade warm air of the blower to dehumidify the electric appliance externally.

The hardest hit area: fabric furniture

Disaster: Sitting on the fabric sofa, I feel the steam is very heavy.

Prevention: 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 interior space of fabric furniture through the gap of fabric. The damp condition of fabric furniture can only be eliminated by external drying. You can turn on the heater and blow it on the fabric sofa for about half an hour, or you can gently blow the sofa surface with a hair dryer, which can alleviate the humidity of fabric furniture.

Wonderful method of moisture-proof and dehumidification

There are many methods of moisture-proof and dehumidification, which can effectively improve the overall humid environment of the home. These moisture-proof and dehumidification methods are effortless to do, and are suitable for busy people to deal with the humid "returning to the south".

Coup 1: prevention first.

It's rare for the sun to shine these days. Why not take this opportunity to dry all the "wet" quilts and pillows in the sun? Prevention is the best moisture-proof and dehumidification method. Generally speaking, quilts, pillows, fabric sofa cover and other home accessories should be placed in the sun for several hours after being used continuously for about one month. Because sunlight is the most environmentally-friendly and effective fungicide, it can not only make the quilt fluffy and soft, but also smell the warm fragrance of sunlight after drying, which will definitely bring you a good night's sleep.

Tip 2: Close the window in the morning and evening.

When the damp "returning to the south sky" strikes, everyone must remember to close the windows at home, especially those facing south and southeast, so as not to give any chance for the moisture eyeing outside the window to sneak in. The most important period of moistureproof is in the morning and evening of every day. The air humidity in 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 house. In addition, if you think that the indoor air cannot circulate because the doors and windows are closed, I suggest you open the window for a short time at noon.

Coup 3: Instrument Method

Moisture-proof and dehumidification can also use scientific and technological means to mobilize all electrical appliances with dehumidification function in the home to reduce indoor air humidity. Nowadays, the air conditioners used in general families have the function of dehumidification. But it takes two or three hours to adjust the indoor air humidity with air conditioner, and it will make people feel very cold indoors. 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 faster, but consumes more electricity. In addition, the heater used for heating in winter can also alleviate the indoor humidity to a certain extent, but the effective radiation range of the heater is small, which can not achieve immediate dehumidification effect.

Tip 4: Hang desiccant.

Now there are many desiccants specially used for moisture-proof and dehumidification in the supermarket. The most common types are moisture absorption boxes and bags. Many water-absorbing boxes have various scents, such as lemon, lavender, sweet orange, etc., which can make the house full of scents and are suitable for being placed in living rooms, rooms, bathrooms, kitchens and other large spaces in daily life. After using it for a period of time, you can take out the substances in the moisture absorption box and buy bulk desiccant and put it in the box for reuse.

In addition, the dehumidifying bag made of water-absorbent resin and charcoal is more suitable to be placed in narrow spaces, such as closets such as wardrobes and shoe cabinets, and a bag of dehumidifying bag can be hung to discharge moisture. In addition, it is quite interesting to make desiccant by hand. Fill a small cloth bag with a proper amount of lime, tie it into a small bag and put it in every corner of the room. Lime itself has the function of absorbing water, and can also slow down the indoor humidity.

Moisture-proof articles

Moisture-proof is not only for southerners, but also for northern Renye Fang. Rainy and humid rooms in summer not only affect indoor furniture, but also greatly endanger residents' health and induce diseases such as colds, rheumatism and asthma. Therefore, how to "dehumidify" has become a lot of people's troubles.

Three wonderful methods of damp-proof in living room

Intermittent ventilation method: in rainy days, close the doors and windows facing south or southeast (that is, upwind direction) and only open the doors and windows facing downwind direction, which can reduce the water vapor entering the room. When the weather clears up, all doors and windows can be opened to accelerate the evaporation of water.

Lime moisture absorption method: lime is an adsorbent, and 1 kg quicklime can absorb about 0.3 kg of water in the air. In rainy days, quicklime can be wrapped in cloth or sacks and kept indoors to keep the indoor air dry.

Indoor heating method: burn a pot of charcoal fire in a humid room, put on a stove (pay attention to ventilation), raise the indoor temperature, so that water vapor can not condense, thus reducing indoor humidity.

Moisture-proof tips for household items

solid wood furniture

Use special cleaning agent for solid wood furniture. The focus of maintenance is to keep luster. Apply the special furniture cleaner evenly on the furniture surface on weekdays, and then gently wipe it.

Fabric sofa

You can dry it with a hair dryer. For the fabric sofa with higher price, it is necessary to use a special vacuum cleaner to absorb all the dust on the surface. In wet weather, gently blowing the sofa with a fan can remove the moisture in the sofa.

Steel art furniture

When stains are found, touch up the paint in time. Wrought iron furniture should always be scrubbed with wet cloth and soft detergent, and pay attention to waterproof and moistureproof. If spots appear on the faded surface, it should be repaired and painted in time to avoid affecting the overall beauty of its products.

household appliances

When the humidity in the air is too high, water vapor can easily adhere to the surface and inside of electrical appliances. When the machine is turned on, it sometimes makes a hissing discharge sound because of water vapor; Even the images and sounds on the screen are blurred. Household appliances should be used frequently in summer to prevent moisture.

Kitchen and bathroom

As long as the materials and technology are well grasped and the edges and corners are well handled, the possibility of water leakage in kitchen and bathroom will be small, and the problem of moisture prevention will be solved.

skill

Taken the kitchen, bathroom wall waterproof layer, waterproof layer construction height of not less than 30cm. If the wall itself is a lightweight wall, then the whole wall must be waterproof.

★ Moisture-proof material is not equal to waterproof material. The moisture-proof effect is produced by infiltrating moisture-proof agent into the board substrate, and the moisture-proof agent has no effect on the waterproof performance of the board itself. So moistureproof only affects the moisture in the air.

★ You can buy some practical moisture-proof small items, such as moisture-absorbing boxes and bags. The prices of these two dehumidifiers are generally around 10 yuan/box/bag.

Demoulding product

It is sultry in summer, and sometimes it rains frequently, which often leads to long hair or mildew spots on the walls or clothes of the room. These "hairs" and mildew spots are mainly molds. The amount of mold in living environment is closely related to temperature and humidity. Moist summer and rooms that use air conditioning for a long time without paying attention to ventilation are places that mold likes to visit.

Mold is harmful.

Fungal infection

The warm and humid environment is conducive to the growth and reproduction of mold, especially the mold that was originally in a "closed" state on human skin, which will "revive" and spread in toes and other parts, causing beriberi. If athlete's foot is not treated in time, it will spread to other parts of the body and become tinea corporis, tinea cruris, tinea manus and tinea versicolor. Studies have shown that mold can also grow and reproduce in the human body, causing fungal pneumonia and other diseases.

Respiratory allergy

Allergic diseases: Inhalation of mold in sensitive person can cause respiratory allergic symptoms, ranging from stuffy nose, runny nose and sneezing, and in severe cases, it can make people have difficulty breathing and wheezing. Mold and its metabolites enter the human body through various channels, and can also cause allergic bronchitis, bronchial asthma, hay fever, dermatitis and so on. , or make the original allergic disease relapse.

arthralgia

Due to the changeable temperature and high humidity in the air, it is easy to aggravate or worsen the conditions of rheumatoid arthritis and rheumatoid arthritis. It can also lead to lumbar strain, sprain, fracture and pain in surgical incision and adjacent joints.

food poisoning

In a hot and humid environment, food is easily polluted and moldy. People who eat this moldy food will directly or indirectly cause poisoning, vomiting, diarrhea and other symptoms. Studies have shown that eating food contaminated with aflatoxin can lead to liver cancer, stomach cancer and other diseases.

Cardiovascular disease

Meteorological factors such as air pressure, temperature and air humidity change greatly in rainy season, which can easily lead to autonomic nervous dysfunction, vasoconstriction, blocked blood flow, increased blood pressure, increased myocardial oxygen consumption and increased heart load, thus inducing cardiovascular and cerebrovascular diseases such as myocardial infarction and stroke.

Four tricks to remove mold

Studies have shown that mold is afraid of light, oxygen, cold and dryness. In view of these characteristics of mold, relevant anti-mildew measures can be taken.

Exposure. Mold is afraid of sunlight, especially ultraviolet rays in sunlight. Ultraviolet rays can kill or inhibit the growth of fungi. Therefore, if the moldy things are exposed to the sun, mold can't survive.

Ventilation. Mould likes warm, humid and dark environment. According to experiments, when the temperature is about 25℃ and the relative humidity of air is 70%, mold is the easiest to grow and reproduce. Therefore, often opening windows to keep indoor air circulation can reduce the number of indoor molds.

Dry. Studies have found that people living in dark and humid rooms have a higher incidence of allergic asthma. Keeping the surrounding environment dry can make the moisture on the surface of moldy objects volatilize, and the indoor humidity will also decrease, so that molds lack the moisture needed for growth and reproduction.

Calm down. According to research, mold can't reproduce below 5℃. Therefore, putting food in the refrigerator and freezer can achieve the effect of mildew prevention.

Special reminder

★ Inhaling and eating food contaminated by mold through respiratory tract is the main way for people to contact mold and its metabolites, so moldy food should be treated in time and must not be eaten.

★ Some molds are poisonous, such as Fusarium, which exist in moldy grains. Some fungi can produce toxins, such as Aspergillus flavus. No matter what kind of food contaminated by fungi is eaten by mistake, it will cause acute or chronic food poisoning.
