Now people are very concerned about physical health, what is the indoor formaldehyde concentration s

The formaldehyde content of the national standard is not higher.

mg mildly contaminated.

Symptoms: susceptibility to colds, weakened immunity, dry throat and sore throat when waking up in the morning, etc.

Suggestion: Spray bedrooms, living rooms....

mg mg m3 heavily contaminated.

Symptoms: cough, respiratory discomfort, indoor flowers and plants are easy to die, etc

mg mg m3 or above is extremely polluting.

Symptoms: Asthma, etc....Susceptible to leukemia, lung cancer, etc....

There are a few ways to remove formaldehyde:

One: open more windows for ventilation, and put it for as long as possible.

Two: with plants, spider plants or herbs Diya.

Lynn et al. decompose formaldehyde.

Three: activated carbon, nano live ore and other adsorption materials.

Exceeding this range is exceeded. You can put some spider plant plants, you can also put onions, vinegar and other things that can absorb odors, the most important thing is not to be in a hurry to live in, with Huankang nano aldehyde enzyme comprehensive treatment, although it is better to open windows for ventilation for a period of time.

The formaldehyde content of the national standard is not higher than ,,mg mild pollution.

1. Soil method: tea residue, grapefruit peel, onion slices, pineapple pieces, etc. are placed in the newly renovated room or fumigated with white vinegar throughout the room. However, this method generally only removes the smell and basically cannot absorb formaldehyde.

2. Ventilation method; The best way to do this is natural ventilation, where convective air movement brings harmful gases out of the room.

3. Plants; Plants have a strong ability to absorb formaldehyde, such as cacti, spider plant, reed, ivy, iron tree, chrysanthemum, etc. Generally speaking, plants with large leaves and vanilla have a better effect on absorbing formaldehyde, such as spider plant, tiger tail orchid, etc.

4. Physical adsorption method: some materials have the characteristics of porous structure, such as nano live ore and other materials, this small pores can contain formaldehyde, toluene and other harmful gas molecules, so it is a good formaldehyde removal material.

5. Or use some herbal Diallin content air purifier. This one is the most useful and fastest.

Hope years old you help.

Indoor air quality testing measures whether the house meets the health requirements of the living environment, based on the standard GB T18883-2002 indoor air quality standard.

Indoor environmental pollutant detection Civil construction engineering and interior decoration engineering environmental protection acceptance testing, based on the standard GB50325-2001 civil construction engineering environmental pollutant control code.

Class architecture ;

Quasi-civil construction projects: residential, hospital, elderly buildings, kindergartens, school classrooms and other civil construction projects;

Civil construction projects: office buildings, shops, hotels, cultural and entertainment venues, bookstores, libraries, exhibition halls, gymnasiums, public transportation waiting rooms, restaurants, barber shops and other civil construction projects.

The national standard is lower, and the international standard is.

In addition to formaldehyde to ventilate, it is best to stay in the house for more than half a year after decoration, if you have to live in a hurry, you can use other methods, open doors and windows to release formaldehyde odor, pay attention to the time and method, otherwise it will cause cracking of the wall, affecting the decoration effect.

Plant purification method, the most common indoor plants are aloe vera, spider plant, tiger tail orchid, one-leaf orchid, monstera bamboo, they can remove harmful substances in the air, especially formaldehyde.

It is better to leave the newly renovated house for a while before living. Because the current paint, wood, etc. contain substances that are harmful to the human body, especially formaldehyde, which is very harmful to the body.

The criteria are: Formaldehyde has a serious harm to human health, when the indoor formaldehyde reaches a certain concentration, the human body will have discomfort, greater than the formaldehyde concentration can cause eye redness, itching, throat discomfort or pain, hoarseness, chest tightness, asthma, dermatitis, etc. The release of formaldehyde is long-term, with a period of 3 to 15 years, so it is necessary to pay more attention to this piece in daily life, and it will be safer to adhere to the treatment.

Here's what I've used before, you can refer to:

1. After ventilation, use some photocatalyst and photophyll materials, photocatalyst needs light to play a role, photophyll is its upgrade material, it is pure plant extraction can also adsorb and decompose formaldehyde and other harmful substances without light, and is an indispensable helper in daily life.

2. Plant selection aloe vera, spider plant, tiger tail orchid, one-leaf orchid, and monstera are natural formaldehyde purifiers, which can not only help purify the air but also decorate the living room to make a pleasant mood.

3. Place more activated carbon adsorption in the corner of the home, and remember to dry each one outdoors to release the harmful substances that have been adsorbed.

1. The national standard of the People's Republic of China "Solid Wood Parquet" stipulates:

Class A parquet:

Formaldehyde emission less than or equal to 9 mg 100 grams;

Class B parquet:

Formaldehyde release is equal to 9 mg - 40 mg 100 g.

2. "Technical Requirements for National Environmental Labeling Products - Artificial Wood Panels" stipulates:

The formaldehyde emission in man-made panels should be less than milligrams of cubic meters;

The amount of formaldehyde released in wood flooring should be less than milligrams of cubic meters.

3. The National Standard of the People's Republic of China "Hygienic Standards for Formaldehyde in Indoor Air" stipulates:

The maximum allowable concentration of formaldehyde in indoor air is milligrams of cubic meters.

The European E1 environmental protection standard is: formaldehyde content 9mg 100g.

The E0 environmental protection standard is: formaldehyde content 3mg 100g.

However, with China's current E0 environmental protection standard: formaldehyde content 5mg grade is 15mg 100g. Europe divides wood products into three levels according to the formaldehyde emission content:

E1 (formaldehyde content less than 10mg 100g,), E2 (formaldehyde content less than 30mg 100g), E3 (formaldehyde content less than 60mg 100g).

The house is simply the most important thing in life, we can have a happy life that can be expected with it, it gives us shelter from the wind and rain, provides us with a warm environment, which is why it is valued by people, the first thing to buy a new house is to decorate according to their preferences, some people like a clean and fresh style, some people like a noble and elegant style,However, there is a problem that cannot be ignored in either style. That is the harmful substance in the renovation.

Among these substances, we probably know the most about formaldehydePeople have long recognized its harm, and use a variety of methods to solve this problem, the most commonly used is to open the window after decoration ventilation for a few months and in the physical plant to clean the air, but these two methods are often not so useful, the most effective way to solve the problem is to find it from the source, that is, to use less formaldehyde content when decorating.

Most people like bright colors and textured furniture, such furniture is placed in the interior is very stylish, can enhance the happiness of life, but in order to look good, many furniture in the production of materials will exceed the formaldehyde standard, in the indoor to the human body is very harmful.

Some decoration paints are very popular with the public, but these paints also have a lot of unqualified placesPaint is most likely to exceed the formaldehyde standard, so we must be careful when choosing paint and other decoration materials, and try to choose a guaranteed brand, which can greatly reduce the probability of formaldehyde poisoning.

1. All kinds of phenolic resin-based plates, used as decorative wall materials, panels, ceilings, etc. Such as plywood, blockboard, fiberboard and particleboard, etc.

2. Decorative materials containing formaldehyde can be dissipated to the outside world, such as wall cloth, wallpaper, paint and paint pipes;

3. Indoor display and daily necessities that may emit formaldehyde, such as furniture, chemical fiber carpets and styrofoam.

It is decorations and decorations containing formaldehyde. When decorating a new house, you should pay attention to the proportion when buying materials. After the decoration, it should also be ventilated in time.

Because the adhesive used in bonding contains formaldehyde, the man-made board will also carry formaldehyde residues, especially the fiber density board and plywood use a lot of glue. All kinds of lacquers and coatings are also indispensable decoration materials for decoration, which can play a certain role in decoration and protection of furniture. However, paints and lacquers also contain formaldehyde, so lacquers and paints themselves, including furniture that have used paints and lacquers, continue to release formaldehyde, causing indoor air pollution.

Soft furnishings such as curtains, sofa covers, etc., which seem to be safe, are actually prone to excessive formaldehyde, because adding formaldehyde during production can improve the toughness of the fabric and prevent it from fading. Therefore, when choosing this kind of jewelry, you should pay attention to its **, and don't be greedy for cheap. Man-made panels are currently used in large quantities, and this material is also prone to excessive formaldehyde.

In its production process, a lot of adhesives will be used to bond, and as we all know, "no formaldehyde, no glue", naturally its formaldehyde content will not be less, and you should be cautious when choosing.

The more paint we use when decorating, the more formaldehyde will be.

Paint, this must be used a lot of formaldehyde, the smell is very big, and there is a new kitchen, new furniture to buy too much.

It is used as a decorative wall material, panel, ceiling, etc. Such as plywood, blockboard, fiberboard and particleboard, etc. furniture, chemical fiber carpets and styrofoam, etc.
