The national standard is that it is already seriously exceeded, and it must be treated in a timely manner, because formaldehyde is continuously volatile, and the release life is relatively long, and the release life of formaldehyde in some materials can even reach 3 to 15 years, so it is difficult to completely remove it in a short period of time.
1. Wise Stone.
It is a very popular purification product on the market in recent years, the main reason is that it has the dual function of absorption and decomposition, can actively absorb free formaldehyde in the air, and does not have to worry about the influence of external factors such as temperature, humidity, light, etc. The adsorbed formaldehyde will also be decomposed into water and carbon dioxide and discharged from the body, without drying and no secondary pollution. When choosing, it is important to note that it is a gray ore with an irregular shape and is not a round particle.
2. Plants.
Plants are the best products provided by nature to remove formaldehyde, and the more respected ones on the market are: pothos, spider plant, ivy, and aloe vera. These plants are a combination of beauty and talent, both to decorate the home and to purify the air
3. Open windows for ventilation.
Open the window ventilation is the best way to remove free formaldehyde, when the window is opened, there will be a steady stream of fresh air will dilute the indoor air containing formaldehyde to achieve the purpose of purifying formaldehyde, but the window is easily affected by the weather, and the effect is also affected by the house type when used.
Fourth, photocatalysts.
The main principle of photocatalyst is that the spray will adhere to the surface of the object to form a strong film, on the one hand, it will slow down the release of formaldehyde, on the other hand, it will contact with the film during the release process, and oxidize formaldehyde by using the photocatalytic performance of the photocatalyst. However, in daily life, the film may oxidize and wear, and the effect will be halved.
Fifth, high temperature.
High temperature can promote the release of formaldehyde, reduce the total content of formaldehyde inside the material, and reduce the release of formaldehyde in the later stage.
In fact, in addition to formaldehyde, everyone wants to control formaldehyde simply, but the process is generally very bumpy, so choosing the right method to remove formaldehyde is the key.
-
Your formaldehyde is exceeded:
There are two national standards, one is the national building standard, the maximum content in the air is milligram cubic meters, and the test requires closed ventilation two hours before testing.
The second is the decoration standard, the Ministry of Health requires that the air content is up to milligram cubic meters, and the indoor air must be sealed for more than 12 hours. The second standard is closer to the state of people when they live there, so the second standard is generally used for air testing now.
So your formaldehyde is exceeded!
-
The indoor formaldehyde concentration requirement is less than or equal to milligrams per cubic meter, that is, the formaldehyde concentration in each cubic meter of air shall not exceed milligrams. Formaldehyde has always been a nightmare for new families, with more and more health accidents caused by formaldehyde, people's awareness of formaldehyde is becoming more and more intense. In fact, we can use the following methods to deal with formaldehyde in new house decoration, saving time and effort.
1.As long as the window is opened, there will be a steady stream of air pouring into the room, and the indoor air containing formaldehyde will be discharged to the outdoors, but due to weather reasons, the window will remove aldehyde when it is windy and rainy, so the window ventilation must be optimistic about the weather forecast!
2.Choose plants that can adsorb formaldehyde, pothos, aloe vera, spider plant and other plants can adsorb a certain amount of formaldehyde pollution, and can indeed remove formaldehyde. Placing some greenery in your new home can also help to beautify the room and freshen the air.
However, the adsorption capacity of plants is relatively limited, and if the formaldehyde concentration is too high, the plants will wilt and die.
3.Activated carbon is a more effective way to purify the air, it has a strong adsorption effect on harmful substances such as formaldehyde, and the smaller the particles, the better the adsorption effect. It should be noted that most activated carbons have certain adsorption limits, and once saturated, they will no longer be absorbed, but will appear desorption, releasing absorbed harmful substances.
4.The fresh air system is to purify the outdoor air through the fresh air fan, and then pour the fresh air into the room, but because of its cumbersome installation, it must be completed before the decoration, and the first is high, so under normal circumstances, the fresh air system is only suitable for large industrial enterprises or large office areas, as well as families with high budgets.
5.Professional formaldehyde removal companies can also quickly remove indoor formaldehyde and harmful substances, but because China's indoor air purification industry started late, there is no particularly strict scientific norms, in the fish eye beads in the formaldehyde removal company, there are many unprofessional and irresponsible companies, we must keep our eyes open when choosing.
Formaldehyde is released for a long time, and it is often difficult to control formaldehyde in one way, so if you want to better deal with formaldehyde, you still need to combine a variety of methods, so as to show a better aldehyde removal effect!
-
If it is moderately exceeded, find a professional formaldehyde removal company or air purifier, charcoal bag, green plants, and open windows for ventilation.

Decoration air testing process: In strict accordance with GB T18883-2002 and GB50325-2010 standards, the testing personnel will come to collect air samples, laboratory testing and analysis, senior engineers will review and sign, and issue test reports; The cycle is about 3-4 working days.
1. The importance of laboratory testing for formaldehyde and other pollutants: Formaldehyde testing in new houses is related to the life and health of you and your family, and you must experience a rigorous and complex experimental process in order to get scientific test results; The instrument that can measure formaldehyde on the spot is not scientific, the instrument cannot pass the CMA measurement certification, and its cost and reagents are relatively low, so it is mostly free or low-cost testing, and formaldehyde is detected for treatment; It cannot support the protection of life and health.
2. What to do if the formaldehyde detection exceeds the standard: our center will tailor it according to your detection value and decoration situation; While doing a good job of component analysis, trace back to the source of pollution, and give you a scientific solution and recommended use time.
3. What kind of suggestions will the industry authorities give about the removal of formaldehyde: the traditional formaldehyde treatment process is mostly high-temperature fumigation, spraying aldehyde remover, spraying photocatalyst, releasing ozone, etc.; Such processes can produce secondary pollutants as well as corrosive furniture. Formaldehyde is generally used as an adhesive, mostly existing in the inside of the board, so it cannot be used; Moreover, indoor pollutants are not only formaldehyde.

If the formaldehyde content per cubic meter in the air exceeds the milligram, it proves that formaldehyde has exceeded the safe range, at this time we must pay attention to it, formaldehyde problem should not be underestimated, if you live in an environment where formaldehyde exceeds the standard for a long time, it will be harmful to human health, the following is for you to introduce some methods of removing aldehyde, I hope you will adopt.
1. This is a gift from nature to us, and it is the most economical way to remove aldehyde, as long as the window is opened, fresh air will enter the room, and formaldehyde will be purified by dilution.
2. Plants can remove formaldehyde, although formaldehyde can be removed, but the amount of formaldehyde absorbed by it is very limited, and when the indoor concentration is high, if the plant simply relies on the adsorption of formaldehyde, its dosage is very large.
3. There are a large number of irregular pores inside the activated carbon, among which the pores similar to the formaldehyde molecule will adsorb formaldehyde, which can achieve the purpose of purifying the air, but the number of internal pores is limited, and it may cause secondary pollution when the adsorption is saturated.
5. The fresh air system is a system that filters the outdoor air and transports it to the room through the pipeline, and discharges the harmful substances contained in the room from the corresponding pipeline.
6. We all know that formaldehyde is volatile at high temperature, and we can use some heating equipment to increase the temperature at home a lot, so that a large amount of formaldehyde gas can be volatilized, and then formaldehyde can be removed by opening windows for ventilation. Repeated operation a few times, you can remove most of the formaldehyde in the home, but we must pay attention to safety when using heating equipment to avoid fire

Super is already a serious excess. Let alone!
-
Formaldehyde exceeding the standard has a great impact. First of all, we can choose materials with low formaldehyde concentration for decorating new houses, so we can quickly and conveniently find ways to remove formaldehyde. 1. Activated carbon adsorption method.
Solid activated carbon has the characteristics of many pores, has a strong adsorption and decomposition effect on formaldehyde and other harmful substances, but is easy to saturate, Ye Guangni is a new type of activated carbon, containing graphene and SOD cellulase, will not be saturated, can be adsorbed and decomposed harmful substances.
2. Ventilation method.
The practical way is to ventilate, if the natural wind is not enough, enough, you can also use an electric fan as an auxiliary tool to speed up the movement of the airflow.
3. Plant absorption method.
Plants have a strong ability to absorb, such as cacti, spider plant, reed, ivy, iron tree, chrysanthemum, etc. Generally speaking, plants with large leaves and vanilla have a better absorption effect, such as spider plant, tiger tail orchid, etc.
The feeling of the testing company actually varies from person to person, and it is recommended that you can find a few more professional testing companies on the Internet to make comparisons, and it is best to have franchisees across the country. Because formaldehyde removal companies in small counties or remote areas are not necessarily professional, they are likely to be treated with unknown potions and a spray gun. >>>More
Greini's air catalyst removes formaldehyde and has a good effect.
Most portable formaldehyde detectors use electrochemical sensors, and HTV is no exception. This sensor is one of the most common gas sensors with high sensitivity, fast response and precise measurement. However, these sensors are susceptible to the influence of other substances that can undergo redox reactions, and problems such as high measured values or unstable readings. >>>More
