How to deal with formaldehyde after the formaldehyde detection exceeds the standard for decoration?

Jincheng Environmental Protection teaches you a few simple and practical ways to remove formaldehyde.

1.Ventilation method.

The ventilation method does not have to be explained too much, that is, through the flow of air, the harmful gases are discharged to the outdoors, which is a simple and effective method, the only disadvantage is that the formaldehyde release cycle is long, generally three to fifteen years, and it is obviously unrealistic to idle the new house for more than three years after decoration. Ventilation alone is not enough.

2.Formaldehyde scavengers or formaldehyde lyses.

Formaldehyde scavengers are chemical reactions that "remove" formaldehyde, the essence of which is to reduce the toxicity of the target substance or convert it into a non-toxic substance.

3.Activated carbon adsorption.

Activated carbon does have an effect in the early stage of use, but the adsorption capacity is limited. Activated carbon generally has a certain adsorption effect on benzene, and the adsorption effect on formaldehyde is not obvious, and the adsorption capacity of activated carbon will be weakened after one month.

4.Photocatalyst removes formaldehyde.

Photocatalyst is the best quality formaldehyde removal product, photocatalyst to play a role, there must be ultraviolet light to excite, and it is impossible to have ultraviolet light in the room all the time, especially in some drawers, cabinet backs and other places where formaldehyde release is most serious, and there is no light. This limits the role of photocatalysts.

5.Plants absorb formaldehyde.

Plants can inhale some harmful substances through photosynthesis, such as: spider plant, aloe vera, cactus, peace tree, pothos, agave, saxifolia, ivy, osmanthus, Brazilian keel, Milan, monstera, etc. However, the usefulness of such methods is extremely limited.

6.Haze doctor air purifier to remove formaldehyde.

In the case that indoor air is already polluted, the use of air purifiers can reduce the degree of pollution to a certain extent, but it does not mean that air pollution can be eliminated at all. It is difficult to remove harmful gases after decoration by one method alone, and it is best to choose several methods based on the actual situation. Minimize harmful indoor gases.

1. Keep indoor air circulation; Keep your home clean and dry, and avoid everyday items that contain volatile organic pollutants. The release period of formaldehyde in the board is three to fifteen years, which can not be solved by raising green plants or opening windows to allow wind. Therefore, formaldehyde removal of all kinds of man-made panels is the focus of solving decoration pollution, and it is also a truly effective method.

2. At present, there are some equipment and technologies to purify formaldehyde in indoor air on the market, which can be used according to their own indoor air pollution.

3. Activated carbon formaldehyde removal is a relatively cheap and practical method, characterized by physical adsorption, thorough adsorption, and not easy to cause secondary pollution. The physical effect of activated carbon is deodorization and detoxification; There are no chemical additives and no effect on the human body.

4. Plant deodorization method. Plant decontamination can be selected for medium and low pollution: general indoor environmental pollution in the environment with light and moderate pollution, and the pollution value is less than 3 times the national standard, and the use of plant purification can achieve better results.

Decoration formaldehyde exceeds the standard, and the following methods can be used to treat formaldehyde

1. Open windows for ventilation

Ventilation is the most basic and important step in removing formaldehyde, insist on ventilation, it is best to open the drawers and wardrobes in the furniture.

2. Green plants

Indoor placement of some green plants, not only can beautify the indoor environment but also absorb formaldehyde, better plants are spider plant, pothos, tiger tail orchid, aloe vera and other green plants can remove formaldehyde.

3. Activated carbon

Activated carbon adsorption is very effective, but the absorption capacity of activated carbon is limited, so it must be replaced regularly, when it reaches a saturated state, it will not only not absorb formaldehyde but also cause secondary pollution.

Fourth, fresh air system

When decorating the home, you can install a set of fresh air system, the fresh air system can exchange indoor air and outdoor air, and dilute indoor formaldehyde and other harmful gases by exchanging fresh air, therefore, the fresh air system has a certain effect on removing formaldehyde and can improve the indoor air environment.

The volatile point of formaldehyde is 19 degrees Celsius, so when the room temperature is lower than 19 degrees Celsius, formaldehyde does not volatilize in large quantities. Therefore, it is necessary to actively create a high-temperature environment. For every 1 degree Celsius increase in temperature, formaldehyde concentrations multiple.

You can turn on floor heating or air conditioning and other equipment, close all doors and windows in the home, accelerate the release of formaldehyde, increase the indoor temperature, and wait until the temperature drops before opening all windows for ventilation, and repeat several times to effectively remove formaldehyde.

Activated carbon can rely on its well-developed pore structure and surface area, which can be exposed to the surrounding air to a large extent, and passively adsorb some pollutants into its own pores, so it is widely used to remove indoor formaldehyde. However, the adsorption capacity of activated carbon for formaldehyde is weak, and the adsorption will reach saturation. Moreover, after reaching saturation, it is easy to be affected by external factors, desorption, resulting in secondary pollution.

Grapefruit peel doesn't actually do anything to remove formaldehyde.

The ventilation method, in which windows are often opened for ventilation, is the most common and effective method at this time.

Plant adsorption method, plants have the functions of purifying the air and adsorbing formaldehyde.

Photocatalyst removes formaldehyde, mainly using the action of light to decompose formaldehyde into harmless substances.

The activated carbon adsorption method can effectively adsorb formaldehyde and other harmful substances in the air by using the tiny voids in the activated carbon.

At the end of the decoration, the decoration in addition to formaldehyde as the main theme, some people think that you are not professional, directly lease Chengdu to choose formaldehyde to be responsible for all affairs, as long as the company is regular, professional, will be a good supplement. Others will choose to go into battle in person, and in any case will inevitably experience fewer detours.

Before indoor formaldehyde removal, we must formulate a long-term development plan, and know how to be ruthless in the peak period when formaldehyde can be released, that is, within 90 days from the date of completion of the decoration design, it is a good time to treat formaldehyde, and it is inevitable that it will be easy to miss. The selection of formaldehyde removal methods for decoration avoids some new enterprise products and methods, which is easy to lead to errors. Formaldehyde removal in new houses should be prevented and removed by double combination!

It should be noted that learning from the experience of formaldehyde removal in new houses is for reference, not a one-to-one copy of other people's formaldehyde removal process, I hope everyone will not misunderstand, thinking that learning is copying, because the density of decoration materials and formaldehyde pollution sources and indoor formaldehyde content are different in each house, so the formaldehyde removal method of each house is different!

In the process of decorating a new house, formaldehyde is something we can't avoid, and it may be present in any corner of the new house. As we all know, the harm of excessive formaldehyde is particularly great, so if you want to stay away from the harm caused by excessive formaldehyde, it is necessary to detect formaldehyde before moving in.

- Since 2020, many high-end places will no longer "remove formaldehyde", and they have done it using high-energy physics technology"Inside cleaning"for a quick and safe check-in.

Guangdong Taichang Environmental Protection Technology Co., Ltd. has been focusing on the research of indoor air treatment physical technology for more than 10 years, and has successfully developed the patented technology of "low-temperature plasma sauna" and Taichang 5A air handling machine, using plasma deep penetration technology to carry out sauna-style neutralization reaction on hidden harmful substance release sources such as deep concrete, wood-based panels, paint layers, paint layers, textiles, and mattresses.

Using internal cleaning technology, formaldehyde, benzene, toluene, xylene, ammonia, TVOC, odor and other pollution sources can be used in only 3 days, eliminating the phenomenon. Internal cleaning technology has ended the history of "20 years of chemical agents to remove formaldehyde".

- Do an internal cleaning after the renovation, that is, "detoxification of the whole house", you can:

1. Exempt from the cost of removing formaldehyde and removing formaldehyde many times;

2. Avoid the harm of decoration odor and secondary pollution of volatiles in aldehyde removal potion;

3. There is no need for the house to be vacant, ventilated for several months, half a year or even more than a year to release pollutants;

4. Safe occupancy, all pollutants are far below the national standard limit, and even close to 0;

5. Protect the immune system of the whole family from harm, and protect the health of the elderly, children, women and patients.

Taichang Environmental Protection Sanxin Air Pavilion Cleaning in the house (also known as whole house detoxification).

Decoration pollution has always been a concern. In addition to the contamination released by building materials and furniture, a variety of adhesives will be used. These adhesives may also release harmful gases such as formaldehyde.

In general, you can use a self-test box to test before inviting a third-party testing company to do the test. If you find that the score may exceed the formaldehyde standard, you can find a third-party company to conduct an accurate test. The self-test cassette is similar to a pH test strip.

You can get a portion of formaldehyde by color contrast.

Indoor formaldehyde smells. When the concentration reaches a certain level, it can be smelled. If you can clearly smell the odor of interior decoration, it means that formaldehyde exceeds the standard, which is a serious standard.

From their own experiences, after the family moved into the new home, they collectively caught a cold, had a low immunity, headaches and dizziness. Drop in energy is prone to fatigue and pungent smells, especially when near a certain piece of furniture, I feel tears, etc. A more precise inspection should be carried out as soon as possible, and good ventilation should be maintained in the room.

Formaldehyde can also be detected to some extent by observing the reactions of plants and animals, such as plants wilting and dying after moving into a new house.

After the renovation of the new house, I believe that many friends will prepare a lot of plants to remove formaldehyde, such as spider plant, green rose, tiger pill orchid and so on. Observe the growth of these plants. If there is a large area of wilting, yellowing or disease, it indicates that the indoor formaldehyde exceeds the standard.

Opening a window can remove formaldehyde more quickly. Because opening windows can not only help the indoor temperature rise, but also increase the formaldehyde content in the indoor air.

You can ask a professional formaldehyde measurement company to measure, or you can buy professional instruments for measurement, which is very simple and convenient.

I think you should buy a formaldehyde tester so that you can test the air in your new home to know the formaldehyde content.

I think you should buy a formaldehyde tester and measure the air in your new home to know the formaldehyde content.

I feel that there should be a formaldehyde content tester, so that the atmosphere of the new home will be informed of the formaldehyde content.

I feel that I should have a formaldehyde tester, and then measure the atmosphere of the new home to know the formaldehyde content.

Formaldehyde is an organic solvent, and because of its strong adhesion ability and low cost, it is widely used as an adhesive for boards, so it is also available"No formaldehyde, no glue"said.

In addition to wooden building materials such as floors and doors, including wooden furniture, paints and coatings, and detergents, they may also contain formaldehyde; Even fabric textiles such as curtains and carpets will use dyes and additives containing formaldehyde to achieve the effect of anti-wrinkle, color protection and color maintenance. The traces of formaldehyde can be said to be ubiquitous, and we must pay attention to it in our daily life and do a good job in protection and treatment. Do the front.

How to remove formaldehyde?

1.Open windows for ventilation.

Opening a window is definitely a good way to open the cabinet doors and drawers at the same time, and dilute the formaldehyde and discharge it to the outside through air convection. This is considered by experts to be one of the best ways to eliminate formaldehyde.

It is recommended to keep the windows open for ventilation as much as possible when the weather permits, or plan for a period of time to open the doors and windows for 4 to 6 hours a day to allow air circulation to take away the formaldehyde in the house.

2.Air purifier.

Most air purifiers can isolate particles of different diameters in the room through the filter, which can quickly achieve the purification effect, but the decoration pollutants are gaseous pollutants, and the diameter of the straight and pure is far smaller than the particle pollutants, therefore, most air purifiers are helpless against formaldehyde, benzene and other harmful substances, so we must be cautious when choosing, and it is more reliable to choose products marked with the function of "removing formaldehyde". Comparatively speaking, a stinky machine is a good choice.

3. Plant aldehyde removal method.

Formaldehyde is included, and more than 300 kinds of organic compounds can be detected indoors, so in addition to ventilation, cleaning and other methods, you may wish to use the photosynthesis of plant Hu Flame to adsorb toxic substances to purify indoor air, although the effect is relatively limited, but it is still very good as an auxiliary method and landscaping the environment.

4. Install fresh air system.

The principle of the fresh air system is to filter the outdoor fresh air through the air supply device and send it to the room, the outside air has a high oxygen content, but there are also many harmful gases and germs, and the filtration system of the fresh air can effectively intercept these harmful gases, which not only ensures that the indoor oxygen is sufficient, but also ensures the cleanliness and safety of the indoor air.
