Can you really smell formaldehyde after renovation?

Generally, it can't be smelled, and formaldehyde exceeds the standard by more than 5 times, so that people can smell it. Nowadays, people have a serious misconception about the pollution of new renovations.

1. Formaldehyde is only a small part of the pollution of new decoration, the decoration smell we smell is not actually the smell of formaldehyde, generally formaldehyde exceeds the standard by 5 times or less (most houses exceed the standard by 1 3 times, and there are also more than 5 times the standard, of, not more than 10), the human nose is not smellable. The smell is generally glue, paint, and wood. The solvents used in glue paints (benzene, xylene, ethyl acetate, cyclohexane, etc.) are much more toxic than formaldehyde.

Because there are many dangers of formaldehyde, most people think that it is enough to remove formaldehyde. In fact, the current formaldehyde removal company, the formaldehyde removal method is generally spraying agent. The agent reacts with formaldehyde to form non-formaldehyde substances.

Or it is to form a dense film on the furniture to seal the formaldehyde in the furniture, which is not advisable. What is the difference between spraying and spraying? Paint has been used for thousands of years, and it still produces toxic odors, are these agents safe?

Impossible. If the formaldehyde concentration is reduced, it will bring new pollutants, which will outweigh the losses.

2. Formaldehyde (it should be said that it is newly renovated pollution control) treatment is recommended to try to subtract as much as possible, not to add. Reduce the amount of materials that produce pollutants. For example, find out the furniture with excessive formaldehyde or high odor, and move it outdoors to ventilate and cool for a period of time before using it.

or permanently demolished. But domestic materials, no matter how careful, will always be a little over-standard, and at this time it is best to ventilate.

However, it is not convenient to turn on the heating and air conditioning for ventilation. If possible, it is recommended to use a special air purifier for formaldehyde removal. Generally, this type of air purifier filter is oversized.

The general machine only has one or two kilograms of filter element, and the effect of removing formaldehyde odor is not good. It is recommended to buy more than 3 kg. It is possible that foreign machines are generally only about one kilogram.

Some domestic models are specialized in removing formaldehyde, and the filter element weighs up to 8 kg (Forest C03). Such a machine has a good odor removal effect.

The smell of formaldehyde after decoration can indeed be smelled, and it is particularly pungent. If you are going to use an inferior product, the smell of formaldehyde will be greater, and people who are really smoked can't open their eyes.

After the renovation of the house, some paint smell, some is the smell of painting the wall, many kinds of smells mixed together, not only formaldehyde, formaldehyde smell is not smelled, can only be detected with an instrument, how much is its content?

Generally, it can't be smelled, and formaldehyde exceeds the standard by more than 5 times, so that people can smell it.

There is a smell, especially in a closed room after decoration, formaldehyde has a pungent smell, if you inhale too much, it is harmful to the human body.

If there is more, it can be smelled, if it is less, it is not obvious, but the throat will be uncomfortable, so you should go to such a place less and ventilate more.

If the formaldehyde content is high, it will be more obvious, and if the content is low, it will not be easy to smell.

It is a little pungent, but it is not obvious, it is recommended to ventilate for a period of time after decoration, and do not rush to live in.

The Japanese have never used photocatalyst to remove formaldehyde, Japan has no need to remove formaldehyde in terms of decoration, Japan has extremely high requirements for plates, the material does not contain formaldehyde at all, the photocatalyst is used by the Japanese to paint the exterior wall, the island country is damp, the photocatalyst can kill mold, prevent the wall from mold. Because Diallin is derived from the photoreceptor molecule of plants, its principle is similar to plant photosynthesis, which is more suitable for formaldehyde treatment and removal when decorating new homes.

Photocatalysts are generally used in industrial formaldehyde removal, and if they are used as aldehyde removal in civil buildings, they are generally not suitable for use, because the non-component of light in indoor environment often leads to incomplete decomposition of formaldehyde, which affects the effect of formaldehyde decomposition. Therefore, according to the existing situation, photocatalysts are generally used in tanneries, textile factories, plate factories and other industries for formaldehyde treatment of products, which usually require the participation of ultraviolet light.
