What are the places where the formaldehyde exceeds the standard in the newly renovated house? How is

1.Glue. Formaldehyde plays a stabilizing role in glue, and glue cannot exist without formaldehyde.

For the beauty of the house, will make a variety of roof shapes for the home, the gypsum board used at this time is also the source of formaldehyde, because a large amount of coagulation glue urea-formaldehyde resin used in bonding gypsum board volatilizes a large number of high concentrations of formaldehyde, polluting the air.

2.High-density pressed panel flooring. If the formaldehyde content of wood is small, but most of the wood floors are high-density pressed boards, which contain a large amount of urea-formaldehyde resin, which is the culprit of excessive formaldehyde, all over the whole corner of the home, so when choosing decoration, it is necessary to choose good quality, natural and environmentally friendly.

3.Latex paint. Latex paint is also a volatile organic compound of free formaldehyde, at present, some large brands of latex paint topcoat, and primer are water-based, water-based latex paint environmental protection indicators are much better than ordinary latex paint, the content of harmful substances in latex paint diluted with water is greatly reduced, so do not use oily products to paint the wall.

4.leather furniture. Some people like leather sofas, leather beds are hidden in the home formaldehyde hazards, formaldehyde is wrapped in the processing of leather, ** cheap quality leather, in order to achieve the gloss of the leather to use a large number of spraying and stabilizer, but the stabilizer is formaldehyde.

Excessive formaldehyde is inevitable.

Formaldehyde is a carcinogen, which is harmful to human health and has become an invisible killer in people's lives. Especially in the renovated new house, formaldehyde is hidden in all corners of our lives, and the decoration of formaldehyde exceeds the standard, which seriously threatens the health of the family, so we must do all kinds of ways to completely remove the formaldehyde in the home.

After you have a house, it will definitely be time to carry out the renovation work. However, this job is not as simple as it seems, and there are too many things to pay attention to. In addition to comfort, safety is even more important.

Of course, this safety is not only structural, but also chemical.

What are the places where formaldehyde is easy to exceed the standard in a newly renovated new house? Dad, what do you usually introduce? Then you are a new house after all, there must be formaldehyde, and anything new will exceed the standard, then you must buy things from Hualian Building to fake money, they are all very beneficial to keep the formaldehyde in fidelity, so such things must let you buy at ease, fake one pays ten.

I used to think that it was large pieces of furniture that had excessive formaldehyde, but later I watched my father's evaluation, and only then did I know that small household items such as cribs, magic wipers for washing dishes, and palm mats are also high-risk areas with excessive formaldehyde. For example, the palm mat itself does not contain formaldehyde, mainly because if a poor quality glue is used in the production of the palm mat, there may be a problem of excessive formaldehyde.

The room size is small. Once the area of the room is small, it is easy to cause the volatilized formaldehyde to exist in this small room, because the calculation of formaldehyde exceeding the standard is calculated as milligrams per cubic meter, the smaller the cubic meter, the higher the formaldehyde concentration, and the easier it is to exceed the standard.

First of all, let's first understand where the formaldehyde in the home comes from?

1. Walls. The wall can be said to be one of the biggest sources of formaldehyde pollution in the process of new house decoration, mainly because when painting the wall, a large amount of glue needs to be used to stick the paint to the wall, and where there is glue, there will be formaldehyde.

2. Flooring. I believe that many families will choose wooden floors instead of tiles when decorating, either the whole house or the bedroom, because it is not only warm, but also beautiful, but you may not know that even if it is an environmentally friendly material, there is a superposition in a certain space, which is likely to lead to excessive formaldehyde content. Over time, formaldehyde will gradually evaporate.

3. Furniture. The new furniture that everyone buys, such as beds, tables, chairs, sofas, cabinets, and wardrobes, is also a major source of formaldehyde pollution in new houses. Therefore, in procurement, we must choose products with low formaldehyde content and meet national standards, but we must not be greedy for cheap and buy inferior products, resulting in serious excess of indoor formaldehyde.

In addition, some fabrics such as curtains and carpets at home will also contain a small amount of formaldehyde, so we must pay attention to the formaldehyde problem in the new home and do a good job in removing aldehyde in daily life.

Which places in a new house are most likely to exceed formaldehyde?

1. Customize a room with a large number of furniture.

For many small houses, customizing furniture can effectively improve the utilization of space, so it is the choice of many people. However, this also means that a lot of boards are used. If the board is not an environmentally friendly material, then it is easy to lead to excessive formaldehyde in the new house.

In addition, the formaldehyde release of the board is also related to the finishing and edge banding process, and the formaldehyde is more likely to exceed the standard if the workmanship is not good, so it is necessary to carefully choose customized products when customizing furniture and using boards.

2. A room with tatami mats.

Tatami mats have always been loved by young people because of their beauty, fashion and novelty. However, since there is no particularly good tatami mat brand in China, it is up to the merchants themselves to decide what kind of glue and lacquer to use. If some businesses, for economic interests, use inferior materials, then it is easy to lead to excessive formaldehyde.

Another point is that the area of tatami rooms is generally relatively small, and if the furniture in the room is too dense, it is easy for the formaldehyde in the tatami room to exceed the standard.

3. Indoor floor material and workmanship.

In the process of decorating a new house, many people use wooden floors, and if it is wood, there is almost no formaldehyde. However, the wooden floor, most of which are high-density pressed boards, contains a large amount of urea-formaldehyde resin, which is the culprit of excessive formaldehyde, almost all over the entire corner of the home, so when choosing decoration, you must choose high-quality, natural and environmentally friendly wooden flooring.

October 10, 63 lunar calendar Rabbit The solar calendar is November 25, 1963 Monday If the birthday is Sagittarius Cheerful, active in thought, pay attention to cultural cultivation and do not forget to look at the world.

The substance that produces formaldehyde is generally mainly adhesive, if you have more furniture composite boards, compression boards, and more places where glue is used, the amount of formaldehyde will be more; There are many volatile substances in the paint that are benzene.

Formaldehyde does not only come from interior decoration, but also appears in these places, and must be correctly recognized When it comes to the place where formaldehyde exists, everyone must have thought of the new home that has just been renovated. Because the decoration of the house needs to use plates and also need to buy furniture, the smell is particularly strong, which makes everyone know that it is the existence of formaldehyde, in fact, in addition to the interior decoration, it will also appear in other places.

First of all, we should take a look at the formaldehyde of the newly renovated house must exceed the standard, because in recent years, there have been more places where formaldehyde exceeds the standard, so we will be concerned about this problem, at the same time, we should take a look at the reason why the formaldehyde in the decoration house exceeds the standard. First of all, we have to look at the formaldehyde that has just been renovated to see if the formaldehyde must exceed the standard, because in recent years, there are more places where formaldehyde exceeds the standard, so we will be concerned about this problem, and at the same time, we should take a look at the reason why the formaldehyde in the decoration house will exceed the standard.

Does the formaldehyde of the newly renovated house have to exceed the standard?

Generally, it will exceed the standard, decorate a 100 square meter home, need to use 60 kg of glue (distributed to furniture, adhesives, floors, doors and windows, walls, etc.) formaldehyde excess rate of 70 80!

Decomposes at room temperature for up to 15 years! Slowly release in the "home" of limited space, and be constantly absorbed by the family! According to statistics, the use of aldehyde removal spray has an upward trend, and various packaged sprays can be seen in the market.

However, the sprayer itself stays in the air, and it is also harmful to the human body if inhaled, especially for small children. As a result, it becomes difficult for families with small children to use. Opening windows for ventilation is a universally applicable method of removing aldehydes, as long as there are people in the house, they can safely open the windows to speed up air convection.

During convection, indoor formaldehyde is gradually transported to the outdoors. However, this method is only suitable for short-term use, and cannot be used for formaldehyde.

Why does formaldehyde exceed the standard when decorating a house?

1: Coating. Paint is the raw material needed for decoration, and at the same time it is the most prone to contamination. Large areas of paint create a pungent smell in the interior, which contains formaldehyde, a gas. As a result, newly renovated houses often do not move in immediately.

2: Wooden floors.

In recent years, the popularity of wooden flooring has been well known, and according to experts, low-quality man-made panels are easy to absorb fish into the market. Most of the man-made panels with formaldehyde added are hard and brightly colored. Therefore, everyone should always pay attention when choosing.

3: Sofa and other cloth products.

The piece of furniture that we commonly see when we enter the interior is the sofa, which means that the sofa is also one of the doors. However, there are also many manufacturers who add formaldehyde to the manufacturing process to reduce production costs. Therefore, the purchase of sofas through formal channels.

After the above introduction, I have learned that the formaldehyde of the newly renovated house must exceed the standard, this will definitely exceed the standard, because we use a lot of materials when decorating the house, and the furniture is also very much, no matter what the material, it contains some formaldehyde things, and all the materials are combined into a home, it will produce formaldehyde exceeding, and also tell you why the formaldehyde in the decoration of the house will exceed the standard.

1. Choose a third-party testing company. Generally, individuals cannot directly detect formaldehyde, and this invisible and intangible thing can only be detected by some physical and chemical methods, and they will issue relevant test certificates.

2. Formaldehyde self-test box. This is a simple and easy way to self-test, generally before asking a third-party testing company to test, you can use a self-test box for testing, if you find that the possible formaldehyde exceeds the standard score, you can find a third-party company for precise testing. The self-test box is similar to a pH test strip, and you can get a formaldehyde score by comparing colors.

If the test liquid is blue, it is a sign of exceeding the standard and should be tested by a professional company as soon as possible.

4. Physical and chemical methods: Formaldehyde is mostly detected by physical and chemical methods, which is the most sophisticated method and the method used by third-party testing companies, which ordinary people are not capable of using. The detection methods mainly include:

AHMT spectrophotometry, phenolic reagent spectrophotometry, gas chromatography, electrochemistry, sensor method.

The most reliable way to remove formaldehyde and odor in the house is to dry the house and ventilate frequently, because formaldehyde is widely found in boards, furniture, plastics, electrical appliances and even wall paint, and there is a slow release process, no matter what method is used, it can only temporarily eliminate or absorb the part of formaldehyde that has been released. In practice, there are no shortcuts and special effects, and spraying air fresheners personally believes that it is not advisable to use one odor to press another odor. There is also a few more activated carbon packets; Raise a few pots of green plants such as pothos, etc.
