Damp-proofing is to prevent excessive humidity in the air. Excessive humidity in the air will cause mold to reproduce rapidly, and mold can not only cause items to mildew and deteriorate.
Damage
The vast majority of people experience various troubles caused by dampness and mold every year: clothes often have an unpleasant smell, and they are afraid of being noticed when entering public places; a good white garment and bed sheet develop black, yellow, and brown spots overnight, which can no longer be washed off; beloved handbags, leather clothing, and shoes have to be painfully discarded because they have become hairy, discolored, or deformed; children and adults often experience itching, which is uncomfortable and damages the skin; foot odor is unpleasant; stored mushrooms, Cordyceps, dried scallops, red dates, wood ear, ginseng, and precious medicinal materials have also become hairy and deteriorated, and cannot be consumed…
Cause Analysis
Many people don't know that mold is caused by excessively high humidity in the air. Scientific research shows that when the temperature of the home environment is between 25℃ and 30℃, and the relative humidity exceeds 60%RH, the oxygen in the air is very sufficient, at which time mold will be unusually active and will reproduce rapidly. Therefore, every year during the rainy season, the troubles caused by mold will widely erode people's lives. According to statistics, the economic losses caused by dampness and mildew worldwide every year amount to hundreds of billions of US dollars (referring only to the household aspect).
There are numerous types of mold, including Ascomycetes, Phycomycetes, and Deuteromycetes in the Fungi division. Mold spreads mainly through spores, which are in the form of tiny powder and are not easily visible to the naked eye. Due to their small size and light weight, they can float around with air currents, dust, and the movement of people and objects. During the flow process,
Once they encounter a suitable environment for development (temperature and humidity), they will immediately grow and reproduce. The mildew, spoilage, and deformation of items occur as a result. The mildew of items can cause damage to items and discomfort, and in severe cases, it can affect the health of family members (leading to skin diseases and food poisoning), especially the harm to infants and the elderly with weaker resistance is more direct.
Damp-proof and Dehumidification Methods
There are many methods for damp-proofing and dehumidification, which can effectively improve the overall humid environment of the home.
Prevention is Key
The best way for damp-proofing and dehumidification is prevention. Generally speaking, home accessories such as quilts, pillows, and fabric sofa covers should be placed in the sun for a few hours after continuous use for about a month. Because sunlight is the most environmentally friendly and effective bactericide, it not only makes the quilt fluffy and soft, but also the quilt smells of the warmth of the sun after drying, which will surely bring you a good night's sleep.
Close Windows in the Morning and Evening
When the humid "return of south" weather strikes, everyone must remember to close the windows of the house, especially the south and southeast facing windows, not giving the lurking moisture outside any chance to enter. The most important time for damp-proofing is in the morning and evening, when the air humidity is higher than at noon. If the doors and windows are not closed in time, the moisture will seriously penetrate into every corner of the home. In addition, if you feel that the doors and windows are closed, making the indoor air unventilated, it is recommended that you open the windows for ventilation for a short time at noon.
Instrumental Method
Damp-proofing and dehumidification can also be achieved through technological means, mobilizing all appliances with dehumidification functions in the home to reduce indoor air humidity. Nowadays, most household air conditioners have dehumidification functions. However, using air conditioners to adjust indoor air humidity is slow, generally taking two or three hours, and will make people in the room feel cold. If you are not satisfied with the dehumidification effect of the air conditioner, you can buy a dedicated dehumidifier from the mall, which is faster but consumes more electricity. In addition, the warm air blower used for heating in winter can also alleviate the humid condition indoors to a certain extent, but the effective radiation range of the warm air blower is small, and it cannot achieve an immediate dehumidification effect.
Hang Damp-proof Agents (Desiccants)
Nowadays, there are many damp-proof agents (desiccants) for damp-proofing and dehumidification in supermarkets. The most common are two types: moisture-absorbing boxes and dehumidification bags. Many moisture-absorbing boxes have various fragrances, such as lemon, lavender, and sweet orange, which can make the home fragrant and are suitable for placing in large living spaces such as living rooms, bedrooms, bathrooms, and kitchens. After using it for a period of time, the substance in the moisture-absorbing box can be removed, and loose desiccant can be purchased and put into the box for reuse.
In addition, dehumidification bags made of water-absorbing resin and charcoal are more suitable for placement in smaller spaces, such as wardrobes and shoe cabinets. A bag of dehumidification bags can be hung in closed spaces to expel moisture. In addition, making your own desiccant is also a very interesting thing. Put an appropriate amount of lime in a small cloth bag, tie it into a small bag, and place it in various corners of the room. Lime itself has a moisture-absorbing effect, and it can also alleviate the dampness in the room.
Damp-proof Cabinet Furniture
Damp-proof cabinet furniture has recently appeared on the market. Damp-proof shoe cabinets can store leather shoes, sports shoes, casual shoes, insoles, etc.; damp-proof wardrobes can store leather goods, leather clothing, quilts, baby products, etc.; damp-proof food cabinets can store high-end medicinal materials (such as Cordyceps sinensis) and dried goods; damp-proof general-purpose cabinets can store optical equipment (such as cameras, cameras, lenses), digital products (such as storage devices, optical discs), and precious calligraphy and paintings, stamps, photo albums, etc. The humidity is controlled by setting the humidity itself from 25-60%RH, the cabinet reaches constant humidity, dehumidification is fully automatic, safe and environmentally friendly, and noise-free. In addition to dehumidification, the shoe cabinet can also achieve sterilization, disinfection, and deodorization functions. The product adopts "condensation dehumidification" technology, the principle of which is to absorb the water vapor in the cabinet into liquid and discharge it through a semiconductor condensation device, and then naturally evaporate it into the air outside the cabinet.
Home Damp-proofing
1. Buy 10-20 kg of lime, put it in a wooden box or cardboard box, and place it under the wardrobe or in the corner of the room. When it is not humid, cover it; when it is humid, open the lid. Do not open the windows wide. The lime absorbs moisture, and the room is dry and pleasant.
2. Stir the sugar in a pan. Then put it in a paper bag and place it in a damp place to absorb moisture. Alternatively, you can use lime to absorb moisture as described above.
3. Open the windows frequently to ventilate the room. Underwear and trousers should be regularly sunned to kill bacteria and maintain health.
4. Some wardrobes on the market are equipped with ultraviolet disinfection lamps. You may also consider buying a UV disinfection lamp for regular disinfection.
5. When using a dehumidifier, remember not to put in food with moisture. Because dehumidifiers are different from refrigerators, they dehumidify at room temperature, while refrigeration is achieved by lowering the temperature (refrigerators achieve preservation by lowering the temperature), dehumidifiers cannot achieve preservation.
Archives Dehumidification
Due to underground moisture and moisture in the air, the interior of archives is easily damp, making the materials stored in the archives susceptible to dampness and mildew, which is detrimental to preservation. Many city archives still use some chemical dehumidifying materials (such as pills), which not only have the smell of volatile solids, but also make the air in the storage room very dry, with low negative ion levels and high levels of inhalable particulate matter, which is also very detrimental to the health of archive staff.
Un-environmentally friendly dehumidifying materials will fill the air with liquid or solid small particles. Anything small can become inhalable particulate matter. Pb, Mn, Cd, Sb, Sr, As, Ni, sulfates, and polycyclic aromatic hydrocarbons are heavily polluting substances, generally used as environmental monitoring targets. Fine particulate matter formed by the interaction of sulfur oxides, nitrogen oxides, volatile organic compounds, and other compounds in the air, their chemical and physical composition varies greatly depending on location, temperature, and humidity, which is very harmful to the human body. After inhalable particulate matter is inhaled, it accumulates in the respiratory system, causing many diseases. Exposure to coarse particulate matter can damage the respiratory system and induce asthma. Fine particulate matter may cause heart disease, lung disease, respiratory diseases, and reduced lung function. Therefore, the risk is higher for sensitive groups such as the elderly, children, and those with existing heart and lung diseases.
Therefore, for archives to do a good job of dehumidification, the key lies in choosing suitable environmentally friendly dehumidification materials.
To get rid of the dampness in the archives, we can reasonably treat the floor and walls of the archive room. However, some people believe that since the archives have been dehumidified, there is no need for dehumidification, which is a misconception. Because of the professional field, people are very easy to confuse the concepts of dehumidification and waterproofing, often using waterproof materials and construction methods to deal with dehumidification problems. This not only fails to achieve good dehumidification results, but also leads to irreparable consequences. Dehumidification aims to prevent moisture (water vapor) from entering the archives, while waterproofing aims to prevent liquid water from seeping into the archives. Usually, the requirements for dehumidification are much higher than those for waterproofing. The molecular density of the waterproof layer is difficult to prevent water vapor from passing through. Dehumidification is a hidden project that needs to be handled on the base surface. If problems are found after dampness appears in the archives, it is usually very difficult to make up for them, and the cost will be very high.
To solve the problem of dehumidification in archives, we need to consider several points: the dehumidification material must be environmentally friendly and green, the dehumidification ability should be 100% dehumidification, the dehumidification period should be as long as possible, and it is best to be permanent.
Dehumidification is essential. For the happiness of family life, the health of family members, everyone can properly dehumidify, and using dehumidifiers can also help everyone.
