Is there an easy way to test if a newly renovated house contains harmful substances?

With the improvement of living standards, people pay more and more attention to environmental protection and will choose products with environmental protection labels. However, the owner reported that the decoration materials at home are all environmentally friendly materials, and there is still a pungent smell after decoration. We should be clear that the so-called environmentally friendly materials are not free of formaldehyde pollution, but the relative content of formaldehyde is low.

The national control standards for various environmentally friendly materials only control the materials themselves. A single standard is issued in a limited environment and is not equivalent to a concentration value converted to an indoor air quality standard. That's why sometimes indoor air quality isn't ideal even with a single eco-friendly material.

We can't just use one eco-friendly material for interior decoration. There is at least one bed, wardrobe, walls, curtains, etc. in the bedroom, so there will be another common problem, which is to accumulate more than the standard. Each material is eco-friendly and does not exceed the standard, but if accumulated in one room, they may exceed the standard.

In a certain space, there are two possibilities for formaldehyde exceeding the standard, and there are serious sources of formaldehyde pollution. There are too many sources of formaldehyde pollution, or both, so even eco-friendly furniture will release formaldehyde.

Flooring made of eco-friendly materials does not guarantee the eco-friendly materials used in other cabinet curtains, let alone eco-friendly materials. Decoration must use a large amount of urea-formaldehyde resin binders. Once you've bought eco-friendly furniture, it's hard to guarantee that your home is free of indoor air pollution.

The formaldehyde testing agency detected that so many newly renovated houses exceeded the formaldehyde standard. Formaldehyde should be solved from the source, reduce the emission of formaldehyde in furniture, and control the emission source of formaldehyde.

If you want to decorate the house beautifully and to your heart's content, then simple decoration can't have that kind of visual effect. When decorating, open the windows for ventilation. This method prevents excessive accumulation of formaldehyde in the space.

The formaldehyde release is the strongest during the decoration period. Ventilation can reduce free formaldehyde in the air, it cannot solve the problem of long-term release of formaldehyde by pollutants.

This is due to the superimposed effect of furniture and building materials pollution, so even if environmentally friendly decoration materials are used, the formaldehyde in the home will still exceed the standard. Because glue bonding is indispensable in the installation process of traditional decoration materials, the superimposed pollution of each furniture combination will make formaldehyde exceed the standard.

1.The materials used are environmentally friendly, but the installation process is not environmentally friendly!

If the material is genuinely environmentally friendly, then why does formaldehyde exceed the standard? This may be related to the glue used during installation. Many homeowners tend to focus only on the material itself when decorating, but ignore the seemingly inconspicuous material adhesive.

2.It is also necessary to consider the superimposed effect of furniture and building materials pollution.

In a renovated room, the formaldehyde emission of a single material may be within the safety range stipulated by the state, but in a limited space, the pollution sources of various materials such as flooring, coatings, wallpaper, and home furnishings are added together, and the possibility of formaldehyde exceeding the standard is very high, which is called the "superposition effect".

Although eco-friendly materials are environmentally friendly, they are not formaldehyde-free. The modern industrial level is not completely formaldehyde-free, so for the newly renovated new house, we must do a good job of removing formaldehyde before moving in. The following methods of removing aldehyde are simple to operate and fast to remove aldehyde, so let's learn them together.

Method 1: Air purifier.

Air purifier is a more popular method of removing formaldehyde in recent years, there are many kinds of air purifiers on the market, choose to clearly mark the ability to remove formaldehyde and other decorative pollutants, when choosing a purifier, we must pay attention to the CADR value of the purifier, that is, the output air ratio of the purifier, when the purification value CADR is higher, the higher the efficiency of its air purification. Method 2: Physical adsorption.

Physical adsorption is the safest and most reliable way to remove formaldehyde, carbon ladle and algae are more commonly used adsorption materials, carbon ladle is suitable for light pollution and needs to be dried and replaced regularly, so as to avoid the problem of adsorption saturation. It can adsorb and decompose formaldehyde, and it is sun-free for three years, which is more suitable for urgent or heavy pollution. Method 3:

Plant purification. Green plants also have a certain ability to remove formaldehyde, benzene and other pollution in the new home, but the removal ability is limited, so I put it last. Generally speaking, pothos, spider plant and other purification ability is the best among plants, and many families will place some plants, which are both eye-catching and can purify the air! At the same time, the growth of plants reflects the quality of indoor air quality.

This is the "additive effect of pollution". Even if each material is environmentally friendly, there is a high possibility of formaldehyde exceeding the standard when multiple sources of pollution such as furniture, flooring, paint, wallpaper, glue and so on are added together in a limited space.

The simple and straightforward sentence is that formaldehyde cannot be completely eliminated.

Even if you use environmentally friendly materials, there is also a certain amount of formaldehyde.

One material bidding, two are not exceeded, three 5, 10 and 50, is it over the standard together? Therefore, ventilation is still needed after decoration.

Because environmentally friendly materials are not completely free of formaldehyde, formaldehyde is an oxidation reaction produced by combining air with some materials.

Attention should also be paid to ventilation with environmentally friendly materials, and environmentally friendly materials meet the standards within one square meter, but there are more materials that may exceed the standard.

Now most people decorate, will always fall into a misunderstanding, that is, the use of environmentally friendly materials, the decoration of the house is environmentally friendly, even ventilation is saved, immediately move in, the result is not to make themselves dizzy and nauseous, or serious damage to health to hospital, in fact, whether you are a rough house home decoration, or second-hand house renovation, even if it is the use of environmentally friendly materials, there will still be formaldehyde in the indoor air, which is unavoidable, so when we are facing environmental protection problems, Litian decoration company reminds, We must recognize these four major environmental protection decoration misunderstandings!

Myth 1: Decoration cannot be zero formaldehyde.

Decorate the whole house, the materials used can be a lot, tiles, plates, wall paint, coatings, glue, etc., in fact, each link will produce formaldehyde, all piled together the natural concentration will be increased, even if it is a solid wood board, it is impossible to achieve zero formaldehyde, after processing, and then use glue, coatings, etc., the board that is originally very environmentally friendly, will also be swallowed by formaldehyde.

Myth 2: Green materials are not zero formaldehyde.

Since you want to avoid formaldehyde damage, then when decorating, it is good to choose green materials! Although this idea is good, but the environmental protection material is not equal to zero formaldehyde, the reason why it is called environmental protection material, because its own formaldehyde content is low, to meet the national standards.

Myth 3: Imported materials are not necessarily better than domestic ones.

In fact, imported materials are not necessarily better than domestic ones, and the same quality materials are more expensive than domestic ones, and even some unscrupulous merchants will be sold under the banner of discounted imports, selling inferior products, so when buying materials, you have to keep your eyes open.

Myth 4: If you use environmentally friendly materials, you don't need to remove formaldehyde.

As long as you use environmentally friendly materials, you don't need to remove formaldehyde, you can move in immediately after decoration, if you think so, it is completely irresponsible for your own health, and it is not the use of environmentally friendly materials, you can not remove formaldehyde, you must remember that the decoration must be done correctly to remove formaldehyde, it is not recommended to move in immediately.

The newly renovated house must be ventilated in time to open the windows for ventilation, and to put a little more green plants in the house, ensure that the doors and windows are all open every day, 1 2 hours to achieve the best ventilation efficiency, you can put a little mothballs in the house, so that these harmful substances can be well removed, and a comprehensive test is required before entering the house.

It can be ventilated, or it can be volatilized by increasing the temperature, using some activated carbon, or asking a professional company to remove it.

Be sure to clean all the furniture before ventilating it for a long time. You can put some greenery and you can use some activated charcoal.

Let's talk about a few more auxiliary methods, just auxiliary! Green plants can also be used to adsorb indoor formaldehyde, such as ivy, spider plants, pothos, etc.; Some research institutions have done experiments on the adsorption of formaldehyde by green plants, and the adsorption rate is only maintained at about 1; Take a 90-square-meter interior as an example, if the house has just been billiards for a long time, for example, it is not more than three months to move in, or it has been renovated for a long time, but the doors and windows are often closed and there is no ventilation, then it is best to find a professional formaldehyde removal company to remove it. My second house was renovated for more than a month, and I felt that the smell was quite big, and I was afraid that it would not be good for my health.

<>Greenery is our best friend, it's something that everyone knows. What a sensible slogan to have fewer children and more trees, green plants can photosynthesize. Help us absorb exhaust gases and exhale green air.

Therefore, after the decoration is completed, all corners of the home are placed in all corners of the house, which is easier to understand, through indoor air circulation, the content of harmful substances in the indoor air can be reduced, thereby reducing the serious harm of formaldehyde to the human body. If the content of formaldehyde in indoor air will increase, radon will also increase accordingly, which is more harmful.

Normal new house has just been decorated, because the doors and windows are fully open, the doors and windows that can be removed are best dismantled into the maximum vents, and then the furniture drawers in the room, the cabinet doors can be removed and all are removed, and they can not be dismantled to be fully opened.

This method is especially effective after the renovation is completed, especially in the summer. The specific method is that after the decoration is completed, close all doors and windows, close the house for 1 week, so that the furniture, floor, walls and other internal formaldehyde harmful substances in the house volatilize like a sauna, and ventilate for 3 days after being sealed, the most economical method is to open the window for ventilation, but it takes a long time, according to the different decoration materials, it generally takes 6-12 months, and occasionally the house for more than three years is still exceeded. In addition, opening windows for ventilation causes indoor dust to penetrate into the room, which is also unacceptable to many people.

Then it should be ventilated for almost half a year, so that formaldehyde and other substances can be completely eliminated.

Put some plants and increase ventilation. After a period of time, these harmful substances can be effectively removed.

These substances generally volatilize when heated, so heating the house, letting them volatilize, and then ventilating the room is fine.

If you want to remove these harmful substances from the newly renovated house, then you should open more windows for ventilation and buy some activated carbon.
