Indoor air testingOur country only recognizes the atmospheric sampling method, don't be deceived by the direct reading instrument or the six-in-one sampling instrument. Formal indoor air testing is to close the doors and windows and then use an atmospheric sampler to sample and collect air samples, and the samples are taken to the CMA laboratory for laboratory analysis in a standard environment. The results of the test will be issued with a CMA test report, and those that cannot issue a CMA test report are false (CMA institutions are not allowed to issue reports other than CMA format, that is, all data reports are illegal and untrustworthy).
When a new house is moved in or just renovated, it is necessary to test five conventional items: formaldehyde, benzene, toluene, xylene, and TVOC. Regarding these five test contents, our country has two testing standards:
One is "GB50325-2020", which is a mandatory national standard, which is generally used for tooling inspection....

1. Walls.
2. Wardrobe cabinets and other furniture.
Wardrobes, cabinets, etc., most of them need to be painted with color and more paint. In order to ensure that the paint does not peel off, a lot of glue is also used, so wardrobes, cabinets, etc. will also emit formaldehyde. In addition, the furniture made of solid wood emits less formaldehyde than the furniture of synthetic wood, because many artificial wood needs to use formaldehyde in the processing process, so the formaldehyde content is far greater than that of solid wood.
Solid wood furniture will be more environmentally friendly.
3. Laminate flooring.
In the process of processing composite flooring, formaldehyde needs to be used or formaldehyde is produced, and when the floor is pasted, it also needs to be fixed with adhesive with strong adhesion, so there is more formaldehyde emitted.
4. Wallpaper. Formaldehyde is produced in the manufacturing process of wallpaper. In order for the wallpaper to adhere better to the wall, it is also necessary to use glue and the like to produce formaldehyde.
5. a door. The door needs to be painted, and many of them are processed by artificial wood, and a lot of formaldehyde is used in the processing process, so the door will also emit formaldehyde.

First of all, wall decoration coating, formaldehyde basically comes from wall decoration coating, and the adhesive contains a lot of formaldehyde and benzene, so the toxic substance lies in the glue. Secondly, flooring, because the man-made board is made of wood and some scraps, the board produced by machinery will use urea-formaldehyde resin glue during the period. Finally furniture, some of the panels are combined using scraps of wood and sawdust together with an adhesive.
As everyone knows. Formaldehyde is very harmful to the human body, so how much is formaldehyde harmful to the human body? Formaldehyde is generally found in **?
1. Formaldehyde generally exists in **.

2. How to judge whether there is formaldehyde.
1. If formaldehyde reaches a certain concentration, you may wish to use sensory reactions to judge, which can be determined according to the body's own reaction. If there is formaldehyde in the home, it is easy to feel difficult to breathe when you enter the room, and if you stay for a long time, your immunity will become weaker and weaker, and you may have a foreign body sensation in your throat.
2. Whether at work or at home, if dizziness occurs for no reason during the period of residence, the immunity will be reduced. **Spots and itching are very likely to occur on the surface layer, and it is very likely that there are harmful substances in the environment where people live.
3. If you can smell some odors when you walk indoors, and this smell makes you feel nauseous and vomiting, which is particularly uncomfortable, this smell is very likely to have formaldehyde, and the content is particularly high. If you can't smell the strange smell in the room, and there is no discomfort, it doesn't mean that there is no formaldehyde, only that the formaldehyde content is low.

Glue is used in these cases.
1. Plywood, blockboard, MDF and other man-made boards used for interior decoration.
The adhesive used in the production of wood-based panels contains a lot of formaldehyde, and the residual and non-reactive formaldehyde in the board will be gradually released to the surrounding environment, which is the main body of formaldehyde in the indoor air.
2. Furniture made of wood-based panels.
In order to pursue profits, some manufacturers use substandard boards, or use inferior glue when bonding veneer materials, and the formaldehyde in the boards and glues seriously exceeds the standard.
Other types of decorative materials that contain formaldehyde and may be emitted to the outside world, such as wall coverings, wallpaper, chemical fiber carpets, paints and coatings, etc.
The production of new furniture, the decoration of walls and floors, all use adhesives. Wherever adhesives are used in large quantities, formaldehyde is always released. In addition, some chemical fiber carpets and paints also contain a certain amount of formaldehyde.
Formaldehyde can also come from cosmetics. Cosmetics, detergents, pesticides, disinfectants, preservatives, printing inks, paper, textile fibers and other chemical light products.

Wooden furniture flooring: If you want to install wooden flooring at home, we must pay attention to the choice of wooden flooring, we must choose environmentally friendly wood materials, wood flooring itself contains trace amounts of formaldehyde, if there are children or the elderly at home, you can choose other materials of flooring. This can reduce the amount of formaldehyde released to a certain extent.
Glass glue: the largest formaldehyde is the glass glue used in interior decoration, glass glue is used very frequently in home decoration, and it is a very important decoration accessory.
Coatings: A large number of paints and paints used in decoration also contain a small amount of formaldehyde, although the content of formaldehyde is not high, but it will still cause serious pollution, this is because these substances contain a large amount of benzene, and benzene is not less harmful to human health than formaldehyde.

It exists in a variety of decoration materials, as long as the materials, furniture, and soft decoration used in the decoration of new houses will have different levels of formaldehyde, and various materials are easy to exceed the standard after superposition. Therefore, when we decorate, we should pay attention to the following 3 points, and formaldehyde will be reduced by at least half.
Point 1: Choose environmentally friendly materials as much as possible for auxiliary materials. We need to know that a lot of glue is needed to glue when decorating, and latex paint, paint, etc. will be used to paint the wall in the later stage, so we will use a large number of different kinds of auxiliary materials, and if we use more environmentally friendly materials, the formaldehyde content will be relatively less.
Point 2: Try to choose solid wood for the board. We choose furniture such as wardrobes, floors, and tables, and try to choose solid wood materials when conditions permit. Its formaldehyde content will also be much lower.
Point 3: Try to avoid complicated decoration styles. The complex decoration style brings a variety of materials superimposed, and no matter how environmentally friendly the materials are, they contain formaldehyde, and the formaldehyde content after the superposition will inevitably be much more, so the light decoration style is simple and fashionable, and it will also make the formaldehyde content at home relatively small.
In addition to paying attention to these 3 points, we can use the following methods to remove aldehydes better and faster. Friends who do not pay attention to the selection of materials for decoration can learn without worrying.
Aldehyde removal method 1: Keep ventilation
According to the indoor air quality experiment, it is concluded that ventilation can effectively reduce the indoor formaldehyde content. Therefore, we try to maintain daily ventilation when conditions allow, and we can use fans to blow air when conditions do not allow.
Aldehyde removal method 2: physical purification
Physical purification is currently the safest and most effective way to remove aldehyde, Baizao Na is a laboratory-level professional aldehyde removal material, its advantage is not only faster to remove aldehyde, but also added with a double group of decomposition components, can decompose formaldehyde, three years of sun-free do not have to worry about adsorption saturation and secondary pollution, can continue to purify and decompose formaldehyde, can ensure that the purified new house formaldehyde is not **.
Aldehyde removal method 3: aldehyde removal spray
Furniture, plates and other materials are the main odor of the new house, and the aldehyde spray is a natural aldehyde remover for furniture, mainly natural mineral components, its own safety and non-toxic, pH value is also neutral, there is no harm to the human body and furniture, spraying the surface of the furniture can penetrate the inside of the furniture board, the pollution in the board is induced to accelerate the decomposition, formaldehyde can be purified from the source, and the effect of removing furniture pollution and odor is obvious.
Aldehyde removal method 4: green plant placement
Although the effect of green plants on removing formaldehyde is not particularly obvious, green plants such as spider plant, pothos, tiger piran, yew and other green plants still have a certain effect of purifying the air, which can make the air quality in the room fresher.
