How can we prevent formaldehyde poisoning?

Living in an environment with high formaldehyde content for a long time can cause poisoning in people. People who work in paint or are exposed to formaldehyde, or who have high formaldehyde levels in newly renovated houses, can also cause formaldehyde poisoning. The environment should be ventilated, especially in newly renovated houses, and windows should be opened frequently for ventilation to avoid long-term exposure to formaldehyde.

For the symptoms of formaldehyde poisoning, we should go to the hospital for further examination and targeted **. The ventilation method does not need to be explained too much, this principle is very simple, that is, the harmful gases are discharged to the outside through the air flow, which is a relatively simple and effective method. The only disadvantage may be that the time is relatively long, because the formaldehyde release cycle is long, usually taking three to fifteen years.

It is obviously unrealistic for a new house to be idle for more than three years after renovation, and the ventilation method alone cannot meet the requirements.

If low pollution is taken into account, plant purification is an option. In general, some mild pollution of the indoor environment can be purified by plants. Select and place suitable plants according to the different functions and areas of the room.

Bamboo charcoal is considered to be an expert in drug use. The adsorption capacity of bamboo charcoal is 2-3 times that of ordinary charcoal. Due to its low price, it is also a common material used to eliminate the situation of decoration pollution.

Bamboo charcoal adsorbs formaldehyde, due to the instability of this adsorption, when the adsorption reaches the saturation value, formaldehyde may be released again, we can put the bamboo charcoal bag for two or three days, put it in the sun, and then use it.

The way to prevent formaldehyde poisoning also includes the selection of qualified decorative materials. Now many decorative materials on the market will release methanol, so we must choose some quality assurance of big brand materials, which is very helpful to prevent formaldehyde poisoning, especially the children's room must choose environmentally friendly furniture, to avoid children because of substandard decoration materials and inhalation of excessive methanol.

I think in life, if we want to prevent formaldehyde poisoning, we need more ventilation, in fact, the most important thing is to ventilate more before the price disappears.

I think that in order to prevent the occurrence of formaldehyde poisoning, we should choose formal and environmentally friendly materials, and formaldehyde can be adsorbed through green plants.

The smell of formaldehyde is very large, and we should avoid inhaling the environment we usually come into contact with with this smell. The second is that the newly renovated house cannot be directly lived, and professional people should be invited to clean it up or wait for a while to live again, and the third is that people who usually come into contact with paint should wear gas masks.

Don't live in a renovated house immediately, at least ventilate it half a year ago, and don't buy some inferior furniture supplies.

It can cause bronchial asthma, and then it can also lead to bronchitis, which can also cause congestion of the conjunctiva of the eye, cough **dryness, **itching. When decorating the house, be sure to choose environmentally friendly boards, ventilate and dry for more than a year after decoration, and put some green plants at home, you can put some activated carbon, grapefruit peel. You can ask a company specializing in formaldehyde removal to remove formaldehyde.

Formaldehyde poisoning is followed by shortness of breath, redness, dryness of the eyes and frequent runny nose. To prevent formaldehyde poisoning, it is necessary to ventilate frequently, keep green plants at home, etc.

Formaldehyde poisoning will cause unclear mind and nausea and nausea, and to prevent formaldehyde, we must avoid staying in places with high formaldehyde content for a long time and avoiding staying in a room covered with paint for a long time.

There will be dizziness and nausea, and there will be very fatigue and hoarseness in the throat.

What to do about formaldehyde poisoning? What are the contingencies? How can it be prevented?

There are hundreds of types of indoor air pollutants, such as formaldehyde, ammonia, radon, benzene and its congeners, volatile organic compounds and particulate pollution, each of which is very serious, among many harmful substances, formaldehyde is the most typical. Formaldehyde is a slow volatile substance, as the temperature rises, it will volatilize faster, and in winter, due to the relatively few windows, the space pollution of the secret room will be very serious. In such cases, indoor air pollution removal is necessary.

"Primary titanium" uses high-tech nano-catalytic material photocatalyst technology to spray the product on the surface of various pollution sources, and under the irradiation of light, it has a strong catalytic degradation function on polluting substances, which can complete the decomposition process in a short period of time and completely solve the air pollution problems for residents.

1.Formaldehyde is removed by ventilation method.

Through the circulation of indoor air, the content of harmful substances in indoor air can be reduced, thereby reducing the harm of such substances to the human body. In winter, people often close doors and windows, indoor and outdoor air can not circulate, not only the content of formaldehyde in indoor air will increase, radon will also continue to accumulate, and even reach a high concentration.

2.Plant removal method.

Medium and low pollution can choose plant decontamination or spraying herb Di & Yalin: general indoor environmental pollution in light and moderate pollution, pollution value in the national standard of less than 3 times the environment, the use of plant purification can achieve better results. Choose and place plants according to the different functions and sizes of the room.

In general, in a room of about 10 square meters, it is more appropriate to put two pots of plants with a height of meters.

3.Formaldehyde is removed chemically.

Activated carbon is a kind of physical adsorption, like Huankang nano live ore, which is very safe and harmless to the human body, and the spray can directly target the pollution source to eliminate the pollution from the root. It should be noted that the spray is easy to form secondary pollution, please carefully identify when purchasing.

1. You can put some activated carbon products, some recommended Ye Guang mud, active volcanic ore material, placed in the corner of the house can effectively adsorb and decompose formaldehyde for a long time, compared with general activated carbon, the effect is better and will not cause secondary pollution.

2. Indoor green plants such as spider plant and tiger piran have a certain absorption effect, and living plants have a certain effect of purifying the air.

3. Modern furniture, latex paint, putty, and melamine will contain formaldehyde and other substances, and heating and ventilation are the best formaldehyde dilution methods.

4. In addition to formaldehyde, the practice that does not make much sense is: put vinegar, orange peel, tea, and charcoal. The addition of vinegar and orange peel only masks the smell, and it is not known what substances can be produced by vinegar and orange peel flavor.

Tea and charcoal only have a little adsorption, but due to the small amount of adsorption to saturation, due to factors such as temperature rise, formaldehyde and other harmful substances may volatilize again. Unless the amount is large and changes frequently. If you use daily materials for decoration, open, drying, and ventilation of the new home from 3 to 6 months, a large number of substances on the surface will be dissipated, and the substances within the surface will slowly volatilize, and in the case of good air quality, it is particularly important to maintain good living habits of ventilation.

No matter what is harmful and harmless, it will stay with you for life, just the density of the home.

In general, under the indoor environment of life and work, the following methods can be taken to prevent formaldehyde poisoning. 1) Before decoration, we should fully consider environmental protection issues such as indoor air quality, and take into account the formaldehyde pollution of decoration materials when decorating and designing, and try to avoid and reduce formaldehyde. 2) Decoration does not have to be overly complicated, you must know that any environmentally friendly products are not without formaldehyde, but the content is within a certain range, as little as possible to use decoration materials to avoid excessive formaldehyde poisoning caused by accumulation.

3) In the process of decoration and decoration, the formaldehyde emission of materials must be considered, and the use of artificial panels should be reduced as much as possible, and the amount of glue should be reduced. 4) Formaldehyde treatment of wood-based panels and floors is carried out during the decoration process, and comprehensive pollution control is carried out on newly purchased furniture and sofas. It is best to ventilate for half a year before moving in.

5) After the decoration is completed, ventilate for a period of time, and conduct an indoor air formaldehyde test. The above is how to prevent formaldehyde poisoning, and the following is a brief description of how to remove formaldehyde. In order to completely remove formaldehyde, it is necessary to start from the root cause and select appropriate and effective products for treatment of the release sources of polluting formaldehyde.

For the formaldehyde in the indoor environment and pollution sources, the difficulty of formaldehyde treatment in different pollution sources is different, formaldehyde in the air is the easiest to treat, choose oxidative decomposition, catalytic decomposition products, if formaldehyde pollution is very little, you can also choose adsorption and decomposition purification products, and even without any product ventilation for a period of time can be basically solved; The formaldehyde content in general decorations such as wallpaper, curtains, carpets, paints and coatings is not high compared with wood-based panels and furniture, and the volatilization period is not long. The most difficult to control is the formaldehyde pollution in wood-based panels and their products, because the formaldehyde in the wood-based panels is inside, and because the urea-formaldehyde resin glue used in the wood-based panels has the shortcomings of continuously releasing formaldehyde in the process of moisture decomposition and aging cracking, coupled with the fact that some wood-based panels use inferior urea-formaldehyde resin glue itself due to the unreasonable proportion, there is unfinished formaldehyde due to the unreasonable ratio, so the formaldehyde release of wood-based panels is relatively large, and the more effective product to solve the formaldehyde in wood-based panels and their products is formaldehyde scavenger or formaldehyde scavenger strong type. Formaldehyde scavenger products based on neutralization reaction (also known as polymerization reaction) technology can penetrate into the plate and neutralize with free formaldehyde to generate stable, non-toxic and irreversible solid resin. On the one hand, the product reacts with the existing free formaldehyde to eliminate the pollution caused by formaldehyde release, and on the other hand, the reaction products remain inside the plate, and the urea-formaldehyde resin is naturally and evenly distributed around and wrapped in the gaps of the plate to prevent moisture from entering the plate.

We all know that there are many kinds of decoration materials, not because the material itself contains formaldehyde (because formaldehyde itself is gaseous), but because the material contains a variety of resin adhesives (urea-formaldehyde resin) prepared from formaldehyde. They are not stable, and because these chemical reactions are bidirectional and reversible, they will decompose during use, resulting in free formaldehyde. Formaldehyde treatment is divided into source treatment and later treatment.

The removal methods are generally summarized as herbal dialin decomposition method, chemical reaction method, nano live ore adsorption method and biological method.

Precautions: Ventilation methods are required for both source and later treatment, and electric fans and other means can also be used to assist in ventilation.
