Is formaldehyde really as terrible as the legend?

Formaldehyde is the main cause of many diseases, and the most terrible thing is its carcinogenicity. Coupled with the help of intentional businesses, formaldehyde has now become the biggest polluting tiger in home improvement, and the title of the first murderer of home improvement pollution is well deserved. Formaldehyde is not terrible, because as long as the formaldehyde content does not exceed the standard, it will not endanger human health. We are always afraid of formaldehyde. In fact, formaldehyde is everywhere in our lives. Even the log itself contains about 0. 1 formaldehyde, but it is relatively low. Scientific understanding of formaldehyde allows us to choose building materials that can resist formaldehyde as much as possible in decoration, rather than relying on chaotic online public opinion or personal opinions of merchants. 1. What is formaldehyde? Formaldehyde can be obtained by dehydrogenation or oxidation of methanol under the catalysis of metals such as silver and copper, and can also be separated from hydrocarbon oxidation products. Used as pesticides and disinfectants, raw materials for preparing phenolic resin, urea-formaldehyde resin, vinylon, urotropine, pentaerythritol and dyes. 2. The characteristic decay period of formaldehyde is relatively long, generally as long as 10 years-15 years, and most of them are in a slow release state. The higher the temperature, the faster the release. The main harm of formaldehyde is irritation to skin and mucosa. When indoor formaldehyde reaches a certain concentration, people will feel uncomfortable. More than 0.08m? The concentration of formaldehyde can cause envy, itchy eyes, sore throat, hoarseness, sneezing, chest tightness, asthma, dermatitis and so on. 3. Sources of formaldehyde Wood products (adhesives in all kinds of furniture, beds, cabinets, floors and wooden doors), mattresses, curtains, wallpaper and putty glue. Collection 4. The common misunderstanding of formaldehyde is that formaldehyde is in wood products, while mattresses, curtains and wallpaper are ignored. In fact, these products contain a lot of formaldehyde, such as wallpaper. Many of our wallpaper sellers are promoting the use of good environmental protection glue, such as glutinous rice glue. In fact, we don't know that wallpaper itself is far more environmentally friendly than the glue used to paste wallpaper. The gap between the quality of glue and the quality of wallpaper itself is completely insignificant, and wallpaper merchants rarely provide inspection reports of wallpaper itself or do their own inspection, which has caused a misunderstanding in our current home decoration: buying curtains and wallpaper just depends on the color, which seems to be a simple decoration. As long as the color is right, you can go to Taobao to go to buy buy, and go to buy buy cheaper. Don't care about quality at all. When I found that formaldehyde exceeded the standard, I began to doubt the paint at home. In fact, the formaldehyde content in paint is very small, and even many paint formulas do not contain formaldehyde at all. Unless it's a poor paint, the formaldehyde contained in the general paint doesn't need to be considered at all, and there is very little. Now many paint brands have made some gimmicks, claiming that they do not contain formaldehyde. Hehe, just for publicity. The insiders look funny. At present, acrylic paint itself has little or no formaldehyde. Is it necessary to publicize?

In recent years, many media have reported the harm of formaldehyde. Someone asked, is formaldehyde really that terrible? Yes, it's really so terrible that formaldehyde exceeds the standard. First of all, we need to know how formaldehyde comes from.

Many people don't pay attention to it. After the renovation, office decoration moved in. I don't think formaldehyde is a big deal. This is completely wrong. Formaldehyde is the main cause of many diseases, the most serious of which is its carcinogenicity. Living in a home with excessive formaldehyde for a long time can easily lead to leukemia. In recent years, there have been many such cases. Children at home have lived in such a home for a long time, breathing the air with excessive formaldehyde. Finally, I got leukemia, which was a fatal blow to the children and even the whole family. Of course, serious formaldehyde exceeding the standard is only a case. Excessive formaldehyde is easy to make people dizzy and pungent, causing respiratory problems, the most serious of which is cancer. Therefore, it is very important to remove formaldehyde in time after renovation.

Of course, formaldehyde is not really that terrible. In fact, formaldehyde is everywhere, and its horror lies in the problem of exceeding the standard. As long as formaldehyde does not exceed the standard, it is harmless to human body. Formaldehyde exists in many places, the most common ones are decoration materials and furniture, so we should choose high-grade materials when decorating, and the quality of purchased materials should not be so bad, so we should consider the issue of formaldehyde release. Too inferior decoration materials will release formaldehyde for a long time. Although you ventilate and smell the smell, formaldehyde will continue to be released at a high concentration.

Correct understanding of formaldehyde, and then remove formaldehyde, everyone is not living in the air with excessive formaldehyde, which is the key to ensuring good health.

Formaldehyde treatment is a big business! China industry information shows that the output value of decoration/home improvement/decoration market reached 3.8 trillion in 20 15 years. According to the National Bureau of Statistics, the national commercial housing sales area in 20 15 is1284.95 million square meters (about120,000 sets, excluding second-hand houses and affordable housing). According to the data of "China Air Purification Products Industry Market Special Survey and Investment Strategy Research Report 20 19-2025" released by Zhiyan Consulting, the market scale of indoor environment purification industry in China in 20112.22 million yuan, reaching 39 1.

The above is the data of indoor environment purification industry. Many building materials industries make their products have a very large premium under the banner of zero formaldehyde. The market size of home improvement building materials is 1.06 trillion, with a compound growth rate of 5.5%; The market of home decoration soft clothes 1.59 trillion, with a compound growth rate of 15.5%. According to the current growth rate, it is estimated that the overall home improvement industry in China will reach 6 trillion by 2025. As a result, the market scale of low-formaldehyde and zero-formaldehyde home improvement building materials and soft-mounted materials is by no means below one trillion.

Formaldehyde is really as terrible as the legend, even more terrible than the legend. Many hazards of formaldehyde are also the needs of such a large market scale. The reason is obvious. Only by constantly exaggerating the harm of formaldehyde can these industries have room for survival.

For a simple example, many plate sellers face a huge number of plates every day. The quality of these plates is uneven, but there are no problems such as leukemia. A person who has just moved into a newly renovated house will get sick, and the reason is probably not formaldehyde.

About 4 million people worldwide die from indoor air pollution every year, of which 2,654,380+million children die from decoration pollution! Every year, 1 12000 people in China die from indoor decoration, and more than 98.7% of newly renovated families have formaldehyde exceeding the standard by more than 60%! 99% of children with hematological diseases in the hospital are caused by long-term adsorption of formaldehyde! Every year, more than 2 million people get sick because of formaldehyde pollution, and more than 50% of them are children under 5 years old! These data are definitely not to scare you, but real data, especially children! As one of the most harmful gases to human beings, it is called indoor "killer", especially in China, which seriously harms the health of newly decorated families, especially children, pregnant women and the elderly, so formaldehyde is really as terrible as the legend.

So what should be done with formaldehyde?

The picture comes from the internet.

1, activated carbon:

Activated carbon is a widely used product to remove formaldehyde. Because of its internal structure, it has a strong adsorption capacity. But the problem with activated carbon is that the saturation period is only about 20 days. After 20 days, it no longer has adsorption capacity and cannot effectively adsorb formaldehyde. On the contrary, there is a danger of secondary release. Among the car owners contacted by the author, more than 40% have used activated carbon, which failed to achieve the effect.

The picture comes from the internet.

2, photocatalyst:

Photocatalyst is a kind of catalyst originated in Japan, which can react with ultraviolet rays and decompose formaldehyde (HCHO) into carbon dioxide and water. However, due to the high dependence on ultraviolet rays, it is basically not used in Japan now (the Japanese now use a plant extract to treat plates and decorate), and photocatalyst is still widely used in some families in China.

3. Air purifier:

The air purifier mainly purifies the air. The air purifier has a filter screen made of activated carbon, which can absorb a certain amount of formaldehyde, but it has the same problem as using activated carbon alone, and it will soon reach saturation in a short time.

Formaldehyde is a very toxic and harmful substance. It is actually harmful for people to live indoors with excessive formaldehyde for a long time. Therefore, for the safety of family members, it is necessary to detect and control formaldehyde at home. You can still find a professional testing management company to manage the indoor indoor air testing.

The harm of formaldehyde should not be underestimated, and many unremarkable items may be the culprit.

Formaldehyde poisoning is far and near from our life. In daily life, we don't seem to have much intersection with formaldehyde poisoning, but news about formaldehyde poisoning of children at home is endless. In fact, the threat of formaldehyde has always been around us, especially some small things, which are probably the chief culprit of formaldehyde poisoning in children.

We all know that decoration will cause formaldehyde pollution. It is common knowledge that newly renovated houses and newly bought furniture need to be handled by in addition to formaldehyde. But besides these, we don't know what else is secretly releasing formaldehyde at home. We have already regretted the discovery of formaldehyde poisoning in children. So what else in the house contains formaldehyde? How can we get rid of it and ensure the safety of children?

Pollution source 1, fabric curtains, etc.

Cloth, sheets, curtains and other household items are the most common and familiar things, but people often ignore that they are also an important source of formaldehyde pollution at home. The fabric itself is safe, but after dyeing and special processing, if it is not handled properly, it is also a high probability that formaldehyde will exceed the standard, and these are also the places that are most easily overlooked by everyone.

Pollution source 2. Unqualified clothes and socks

Clothing products are divided into class A and class B, which is not only related to whether clothes can be worn next to the body, but also related to the level of formaldehyde content. Almost all clothes contain a certain amount of formaldehyde, which is nothing more than a question of how much. Buying substandard or fake rated clothes is a great threat to children's health, and we are completely unaware of it.

Pollution source 3, inferior toys

The prices of toys vary greatly. The same toy, the same brand, is several times more expensive than ordinary toys, but from the appearance and function, ordinary consumers are completely confused. In order to pursue cost performance, many people choose cheap ordinary models, but the actual situation is that the price difference is not the style, but the value of the material itself, and the toys with good brands are made in strict accordance with national standards, using safe and environmentally friendly materials, and safety and environmental protection must meet the standards. Ordinary models or especially cheap ones will inevitably cut corners and use some inferior raw materials. When children play with these inferior toys every day, the harm of formaldehyde also affects their health unconsciously.

Therefore, when we buy these products in our daily life, especially those that need close contact with children, we must carefully check the product's qualification and environmental safety, and try to choose brand-name things to avoid harm to children. Then, after understanding these hidden pollution sources, if we encounter formaldehyde exceeding the standard in our daily life, how should we prevent and deal with it? Here are some more reliable in addition to formaldehyde methods:

Method 1: Open the window for ventilation.

Ventilation is the simplest and most effective method in in addition to formaldehyde, which can effectively reduce the indoor formaldehyde content. But in our life, it is inevitable that we can't open the window, for example, we don't have time to open the window or it rains, so we can't just rely on ventilation, so we must use it together with other methods.

Method 2: Adsorption for aldehyde removal.

Activated carbon is the most commonly used product outside in addition to formaldehyde at present. Because of its low price and wide application, it can only adsorb formaldehyde, but can't decompose it. Therefore, the use of activated carbon must be dried regularly once a month or so, and replaced in time about half a year to avoid secondary pollution.

Method 3: Separation of aldehydes.

Baizaona Granule is a laboratory-grade in addition to formaldehyde material. Compared with activated carbon, its advantages are that it can not only adsorb formaldehyde, but also decompose formaldehyde, without secondary pollution and without drying in the process of use. Suitable for people who need to remove formaldehyde quickly and have no time to take care of it.

Method 4: Green plants absorb flavor.

Putting some green plants at home can not only purify the air, but also be beautiful. You can put some green plants that can purify the air at home, such as green radish, chlorophytum, tiger tail orchid and so on, which can purify the air to a certain extent.

It's really scary. Formaldehyde in decoration pollutants is the most harmful to human body and has the longest incubation period. Known as the "first killer of indoor pollution." Formaldehyde is the main cause of neonatal malformation, childhood leukemia and the decline of memory and intelligence of adolescents. It has been identified as a "carcinogen and teratogenic substance" by WHO. Long-term exposure to low-dose formaldehyde can cause chronic poisoning and diseases such as respiratory system, nervous system and reproductive system.

When the indoor formaldehyde seriously exceeds the standard, people will live in the new house with serious formaldehyde exceeding the standard for a long time, which is easy to cause acute poisoning. The manifestations of acute poisoning are: severe skin allergy, sneezing, coughing or obvious rhinitis symptoms, burning throat and sadness. It may even cause abdominal pain, convulsions and even death.

There are three ways to remove formaldehyde:

1, physical adsorption decomposition

Baicaona is a kind of aldehyde removal material highly praised by treatment engineers. Compared with charcoal bag, it not only has ten times faster adsorption and purification speed, but also adds two decomposition components, which can decompose formaldehyde. Sun-free for three years, you don't have to worry about adsorption saturation at home. It is suitable for urgent use, which is also an important reason why treatment engineers prefer it.

2. Natural decomposition medium

Hundred algae spray is a natural in addition to formaldehyde agent for furniture, which is mainly composed of natural minerals. It is safe, non-toxic and neutral in ph value, and has no harm to human body and furniture. After spraying on the surface of furniture, it can penetrate into the interior of furniture board, induce and accelerate the decomposition of pollutants in the board, purify formaldehyde from the source, and remove furniture pollution and odor.

3. Air purifier

Ventilation is greatly influenced by weather and environment. When the weather is bad or you can't open the window at night, you can use it with an air purifier, which can realize 24-hour uninterrupted ventilation and purification. It is also a good choice to use it together.

There are many hazards of formaldehyde, some of which are directly manifested, others are not, and they are potential hazards. The main harm of formaldehyde is the irritation to skin and mucosa. Formaldehyde is a poison of protoplasm, which can combine with protein. When inhaled in high concentration, it will cause serious irritation to respiratory tract, causing edema and headache. If not treated in time, staying indoors for a long time will have very serious consequences.

In the face of such terrible and difficult formaldehyde, you don't have to worry about safe check-in if you master the following three standard methods.

Keep continuous ventilation.

Ventilation is the simplest and most effective method in in addition to formaldehyde. As long as conditions permit, the newly renovated house must be ventilated with more windows. Under the condition of air circulation, the accumulation of indoor harmful gases can be avoided. This in addition to formaldehyde way is almost cost-free and environmentally friendly.

Nano-adsorption decomposition of algae

Baizaona is a professional in addition to formaldehyde material at laboratory level. Its advantage is not only that in addition to formaldehyde is faster, but also that it can decompose formaldehyde by adding two decomposition components. There is no need to worry about adsorption saturation and secondary pollution for three years, and formaldehyde can be purified and decomposed for a long time, which can ensure that the formaldehyde in the purified new house does not rebound.

Decomposition medium permeation purification

Furniture, curtains, wallpaper, floor, wooden door, etc. , is an important source of odor and pollution in the home. Proper use of natural seaweed spray will accelerate purification. It is infiltration-induced purification, which can decompose formaldehyde in furniture plates and further accelerate purification.

Last year, all kinds of tragedies caused by indoor air pollution were still fresh in my mind, and both adults and children were shrouded in the shadow of leukemia. In fact, it may be a bit shocking to say leukemia alone. In fact, formaldehyde affects every aspect of our lives, which may be dizziness, headache, skin allergies, sleep disorders, and even neurotoxicity, a deeper injury. In the dimension of life, we constantly receive information reported by the media, but in fact, our understanding of indoor air pollutants such as formaldehyde is not clear. Some people can see its harm in time, while others are still hiding it. Those lives delayed by formaldehyde cognitive errors are not only numbers, but also the truth.

Aldehydes and other indoor air pollutants can be found everywhere in our home environment. Whether we use wood-based panel furniture, floors, or decorative wallpapers and curtains, harmful substances are constantly being released. Moreover, the existence of harmful substances such as formaldehyde is not only in the first few months of decoration, but also the release cycle will even be as long as 3- 15 years.

Women need special protection during pregnancy preparation and early pregnancy, and their resistance is poor. Even if the indoor formaldehyde slightly exceeds the standard, it will have a great impact on pregnant women and fetuses.

For pregnant women, long-term exposure to low-concentration formaldehyde will also have an impact on the physique of newborns. If exposed to high concentrations of formaldehyde, it will not only be toxic to the mother's nervous system, immune system, liver and so on. It can also induce fetal malformation and infant leukemia.
