1. The best method to remove formaldehyde from a house
1. Ventilation method is to discharge harmful gases outdoors through the circulation of air. This method costs almost nothing and is simple and effective. The disadvantage is that the formaldehyde release cycle is long, usually three to five years, so relying on ventilation alone is unrealistic
2. New houses can use air purifiers to remove part of the formaldehyde and decompose bacteria. For example, this air purifier adopts an integrated touch button design, which continuously releases negative ions and circulates to purify indoor air quality. Air purifiers use activated carbon to adsorb formaldehyde, but the amount of carbon is limited and will gradually fail as it is used for a long time.
3. Formaldehyde scavengers rely on chemical reactions to \”remove\” formaldehyde. The essence of this method is to reduce the toxicity of target substances or convert them into non-toxic substances. substance. Formaldehyde can be oxidized to formic acid or reduced to methanol. Although the toxicity and irritation of these two substances are lower than those of formaldehyde, their toxicity still exists. For example, some highly oxidizing formaldehyde scavengers can oxidize formaldehyde, but they are easy to decompose. Spraying on wooden boards will damage the wood and lose their effectiveness within a few hours. It is impossible to achieve \”one spray and forever.\” Moreover, high-concentration scavengers sprayed in the air will cause new pollution hazards to people. Other oxidants and reducing agents cannot effectively remove formaldehyde, and will introduce similar new pollution.
4. Photocatalyst is also a photocatalyst.It originated in Japan. The photocatalyst is mainly made of nanoscale titanium dioxide solution, which is sprayed on the surface of the substrate using spray construction technology. In this way, under the condition of light, the substrate will catalytically react with the moisture in the air, allowing oxidation and decomposition to be carried out, promoting the production of active oxygen and hydroxyl radicals. Through the strong redox ability of ions, harmful substances such as formaldehyde are decomposed, and the decomposed products are carbon dioxide and water.
5. It is composed of plant extracts and highly absorbent materials, which can quickly remove odors caused by decoration.
6. The active ingredients are extracted from the roots of more than 300 kinds of plants, which can quickly decompose with various odor molecules. They are natural, non-toxic and have no secondary pollution.
7. Activated carbon itself has a certain adsorption effect on harmful substances and volatile harmful gases. It is recommended that if the newly decorated interior or the formaldehyde content itself The environment that exceeds the standard can be effectively adsorbed by activated carbon.
8. The fresh air system is an independent air treatment system composed of an air supply system and an exhaust system. The outdoor air is purified by the fresh air fan and introduced into the room through the pipeline. Exhaust room air.
9. Firefighting forced exhaust is a very important part of the firefighting system. It is linked with the central control and is mainly used to discharge dense smoke from the room after a fire. Currently, the firefighting system The forced exhaust system will be equipped with a smoke exhaust fan and a supply fan, which means that the exhaust fan of the air conditioning system (which can be turned on at ordinary times) and the smoke exhaust fan use the same fan and air duct.
10. The high-speed axial flow fan performs forced ventilation on the site, accelerates the flow of indoor air, and forcibly discharges the air with pollution sources into the room to clean the indoor air. Purpose
11. Plants have a strong ability to absorb formaldehyde. They will absorb formaldehyde and carbon dioxide and release oxygen, such as cactus, reeds, ivy, chrysanthemums, etc. . Generally speaking, plants with large leaves and herbs absorb formaldehyde better, such as Chlorophytum, Sansevieria, etc.
2. How to remove formaldehyde when decorating a new house
1. After renovating their new homes, many people open doors and windows for ventilation. This is because harmful gases such as formaldehyde and benzene are volatile. Opening doors and windows can allow indoor formaldehyde and other harmful substances to be discharged. If the indoor temperature is high, the amount of formaldehyde released will be relatively large. However, because the release cycle of formaldehyde is as long as 3-15 years ago, simply opening windows for ventilation cannot fundamentally solve the problem of formaldehyde pollution. In addition, with this method, be sure to close the doors and windows at night to avoid theft.
2. It is worth noting that formaldehyde is a gas that volatilizes very slowly. If you want to increase the amount of formaldehyde released in a short period of time, it is best to The best way is to raise the indoor temperature as much as possible. You can turn on the air conditioner for an appropriate amount of time to raise the indoor temperature to speed up the volatilization of formaldehyde.
3. If you want to quickly remove formaldehyde, you can also use physical adsorption method. For example, put more activated carbon indoors. It is recommended to place about 50g of activated carbon per square meter. It has a good adsorption effect on formaldehyde. It is worth noting that you should pay attention to the replacement of activated carbon, generally once every 7-8 months. In addition, everyone needs to be reminded that the adsorption function of tea water, salt water, grapefruit peels, onion slices, pineapple chunks, etc. is very weak, and may cover odors, making it impossible to effectively judge the pollution situation, so it is not recommended to use them.
4. In addition, you can also plant some flowers and plants indoors, which can not only green your new home, but also remove formaldehyde. According to scientific experiments, many green plants such as spider plants, cacti, sansevieria, iron trees, chrysanthemums, etc. have a certain ability to absorb formaldehyde. However, the adsorption effect of plants is limited, and some plants are not suitable for placing in large numbers in the room. Therefore, it is unrealistic to completely rely on the adsorption function of plants to solve the problem of decoration pollution.
3. How to remove formaldehyde quickly and effectively in new house decoration
There are many ways to remove formaldehyde. The following are some of the fastest and most effective methods:
1. Ventilation method: This is the most basic method. Open windows to allow fresh air to circulate and carry away formaldehyde. First of all, you need to ensure that the indoor air is dry, otherwise the formaldehyde in the air will evaporate too slowly. It is recommended to ventilate for at least 1-2 hours a day.
2. Indoor green plants: Indoor plants can absorb formaldehyde in the air, especially green plants with large leaves, such as spider plants and monstera. About 6-8 pots of plants need to be placed in a room, which can significantly improve the formaldehyde concentration in the indoor air.
3. Activated carbon: Activated carbon is a good adsorbent and can adsorb formaldehyde molecules. In newly renovated rooms, the amount of activated carbon can be increased to absorb formaldehyde.
4. Photocatalyst: Photocatalyst can produce oxygen ions and hydroxyl radicals by absorbing ultraviolet rays, thereby decomposing harmful gases such as formaldehyde. The effect of formaldehyde removal can be achieved by spraying photocatalyst on walls or floors.
5. Formaldehyde detection and treatment: You can purchase air detection instruments to detect indoor formaldehyde concentration. If the concentration is too high, you can choose to hire a professional formaldehyde treatment company to solve the problem. Question. Although this method is more expensive, it is the most intuitive and effective.
4. How to remove formaldehyde from a new house
1. Formaldehyde will be released very quickly in a high temperature and high humidity environment (when the temperature reaches its boiling point -19°C, for every 5°C increase in temperature, its release rate will be When the humidity increases by 15% to 30%, the evaporation rate of formaldehyde increases by 10% to 20%. This is also true. During heating in winter and high temperature in summer, the indoor formaldehyde concentration will be higher.
2. Therefore, if we want to get a more accurate detection reference value, we need to detect indoor formaldehyde concentration in a high temperature and high humidity environment.
5. How to remove formaldehyde in a new house
1. Ask professional formaldehyde removal personnel to remove it. On the one hand, they Be more professional in indoor formaldehyde control, and secondly, save worry and effort.
2. Open windows for ventilation every day to increase indoor and outdoor air circulation. In seasons when it is inconvenient to open windows, you can use a fresh air fan or fresh air system to replace indoor and outdoor air.
3. Place more plants in the house, especially. They are some round-leaf plants, which are not only effective and safe, but will not cause secondary pollution.
4. Use activated carbon to remove them, but it usually takes 3 to 6 months. Replace with new ones.
5. If you want to increase the amount of formaldehyde released in a short period of time, you can turn on the air conditioner for an appropriate amount of time to increase the indoor temperature to speed up the evaporation of formaldehyde. Speed.
6. Using an ozone generator for one month and two to three hours a day can reduce formaldehyde content.
7. LightCatalyst purifier, under the action of ultraviolet light or visible light, produces catalytic degradation function and plays the role of decomposing formaldehyde.
6. Tips for formaldehyde removal in new homes
1. Open all windows to maintain ventilation;
2. Keep turning the lights on and off to increase the temperature and lower the room temperature to allow formaldehyde to evaporate as quickly as possible;
3. Soak black tea in hot water, and put a pot of black tea in each room to remove formaldehyde through ventilation
Through the circulation of indoor air, the content of harmful substances in indoor air can be reduced, thereby reducing the harm of such substances to the human body. In winter, people often close their doors and windows tightly, and indoor and outdoor air cannot circulate. Not only will the content of formaldehyde in the indoor air increase, but radon will also continue to accumulate, even reaching very high concentrations
This ends the sharing of formaldehyde removal in new homes and how to remove formaldehyde in new homes. If your problem is solved, we will be very happy.
