Newly renovated house, afraid of formaldehyde, I don t know if there is any good solution?

Newly renovated houses remove formaldehyde.

Is formaldehyde difficult to remove in a newly renovated house? Teach you a trick and never worry about formaldehyde at home again

The reasons for formaldehyde in newly renovated houses are: pollution from the outdoor air and pollution from the interior itself.

1. Pollution from outdoor air: industrial exhaust gas, automobile exhaust, photochemical smog, etc. can be emitted or produce a certain amount of formaldehyde at a certain degree of leakage, but the content of this part is very small. The annual average concentration of formaldehyde in urban air is about per cubic meter, generally not more than per cubic meter, this part of the gas can enter the room at some times, and it is one of the most important slags that constitute indoor formaldehyde pollution.

2. Pollution from the indoor itself: mainly the indoor use of chemical products such as building materials, decoration items and daily necessities, but also includes some secondary factors such as incomplete combustion of fuel and tobacco leaves. Formaldehyde has strong adhesion, and at the same time can strengthen the hardness and insect resistance and anti-corrosion ability of the board, so all kinds of particleboard, medium density fiberboard, and plywood on the market use urea-formaldehyde resin with formaldehyde as the main component as a binder, so it will inevitably contain formaldehyde.

A method for detecting whether formaldehyde exceeds the standard

1. Use formaldehyde detector: Formal qualified formaldehyde detector is very expensive, and it is not cost-effective to decorate the house and buy it for testing. At this time, you can ask a professional testing company, there is also a professional management company, ** is also more expensive, according to your actual economic situation to choose.

2. Smell the smell: indoor formaldehyde is smelly, the concentration reaches a certain level, it can be smelled, if you can clearly smell the indoor decoration smell, it means that the formaldehyde is exceeded, which is a serious exceedance.

3. Observe plant growth: After the decoration of the new house, I believe that many friends will prepare a lot of plants to remove formaldehyde, such as spider plant, pothos, tiger pill orchid and so on. This is when we can observe the growth of these plants.

If there is a large area of wilting, yellowing or sickness, etc., it means that the indoor formaldehyde has exceeded the standard.

4. Chemical detection: It is relatively simple to use a portable formaldehyde self-test box, which is still a reference for measurement. With this simple method, the results will be biased greatly, so it is best to prepare more checkboxes and find the average.

The decoration of new houses needs to pay attention to the superposition of formaldehyde, that is, the formaldehyde content of single furniture, coatings, etc. is qualified, but the formaldehyde content in the interior is exceeded. Inhaling excessive amounts of formaldehyde in a short period of time may cause you to feel dizzy, nausea, eyes, nose and throat discomfort, itching, etc. Exposure to excessive formaldehyde for a long time can lead to decreased immunity and even have a malignant effect on physical health.

If you want to stay healthy and secure, it is essential to remove aldehydes effectively

1. Ventilation is the universal law, to ensure a long period of ventilation, and at the same time, it is best to ensure high sleep, clear temperature and high humidity.

2. Aldehyde removal spray: select some high-quality photophyll that decomposes the source of formaldehyde pollution to achieve the effect of removing decomposition. This section has no requirements for light and ultraviolet rays, and will not decompose incompletely.

3. Ye Guang mud, activated carbon. This kind of tung can physically adsorb formaldehyde before, but the activated carbon has the problem of easy saturation and frequent replacement. Ye Guangni is more trouble-free, has stronger adsorption, and can also decompose adsorbates without secondary release.

4. Green plants and flowers. Theoretically, it is effective for the removal of aldehydes. However, it cannot remove aldehydes in large quantities and quickly, so it is mainly used for landscaping the indoor environment.

5. Air purifier. We need to understand that the main function of air purifiers is to deal with outdoor problems rather than indoor aldehyde removal, therefore, this is not as effective as ventilation in terms of aldezha removal, and I personally feel that it is not very necessary.

Above, choose the removal method according to your actual situation, and move into a new home after the wheel is safe.

1. Ventilation method.

The indoor air content of methanol and other harmful gases in newly renovated houses is high, and opening windows for ventilation can promote the air circulation of indoor air and outdoor air, and reduce the concentration of indoor formaldehyde and other harmful gases. The disadvantage is that it is convenient to ventilate at all times, and the release time is more than 3 years.

2. Hot air baking method.

In unventilated rooms, turn on the air conditioner and open the wardrobe doors or drawers to better allow the smell in the furniture and the moisture on the walls to evaporate. The disadvantage is that it cannot be carried out for a long time.

3. Activated carbon adsorption method.

Activated carbon can effectively adsorb formaldehyde in the air, and the effect is good and practical, without any chemical additives. The disadvantage is that it should be changed frequently, and the effect is not obvious for large spaces, and it is only suitable in some small spaces.
