If the new house has not undergone strict formaldehyde testing before moving in, then it is very easy to develop the symptoms of formaldehyde poisoning, and the situation is even worse if there are babies living in the room. In general, the symptoms of formaldehyde poisoning in infants include allergies, frequent colds and other symptoms. Therefore, parents should be alert to the above symptoms of their babies and take corresponding measures. In order to remove the hazards of formaldehyde, air purifiers, activated carbon, ozone sterilization and other methods can be used to purify the air. Let's take a look at the relevant knowledge.
Symptoms of formaldehyde poisoning in infants.
Infants and young children in the period of rapid growth and development breathe twice the amount of formaldehyde, and the intake of pollutants in the air is also greater than that of **. Serious levels of formaldehyde can lead to allergies in infants and young children, and may even cause leukemia. The symptoms of formaldehyde poisoning in infants are as follows:
1. When you get up early in the morning, your baby feels stuffy, nauseous, or even dizzy;
2. The baby is often prone to colds, coughs, sneezes, and decreased immunity, and the newly renovated baby is reluctant to go home;
3. Although the baby is rarely exposed to the smoking environment, he often feels uncomfortable noise, foreign body sensation, and poor breathing;
4. Babies often have allergies and other problems, and they are frequent;
5. After the baby leaves this environment, the symptoms will change and improve significantly.
What to do if the formaldehyde in the baby's room exceeds the standard
1. Use activated carbon.
1. Principle: It can effectively absorb various peculiar smells in the air, and has a good absorption effect on benzene chemicals. However, the physical adsorption method can only temporarily adsorb certain pollutants, and cannot achieve the purpose of eliminating and removing pollutants, and when the temperature and wind speed rise to a certain extent, the adsorbed pollutants may be free and enter the breathing space again.
2. Tips: When the adsorption reaches saturation, it no longer has the adsorption capacity, it is necessary to replace the filter material, if not replaced, the formaldehyde and bacteria adsorbed by it may be released at any time to become a potential threat to home life.
2. Ozone purification method.
1. Principle: Ozone has strong oxidation, is internationally recognized as a commonly used physical treatment method, is not easy to produce secondary pollution, ozone concentration reaches 0Above 1ppm, ozone plays a role in sterilization and odor removal. But up to 0After 15ppm, ozone itself emits a strong foul odor and has the potential to cause cancer.
2. Tips: The harsh practical conditions and possible *** limit the popularization and use of this method, so it is not recommended.
3. Formaldehyde blocking wax.
1. Principle: Enclosing formaldehyde in blockboard is not a practical solution to the problem. The volatilization of formaldehyde is 2 years at the earliest, and decades at the slower. But you don't have to worry too much, because there are several ways to get the air out of the air. The most important thing is the size of the material itself and the space, relatively speaking, the space is large, and if the material is less, the possible coefficient of exceeding the standard will be smaller.
2. Tips: This method is to enclose formaldehyde in the furniture, which can be said to be a symptom but not a cure, and it is not recommended that you use this method to do excessive formaldehyde treatment.
4. Air purifier (photocatalytic technology, molecular complexation technology).
1. Principle: The most common photocatalyst material is titanium dioxide. Under the action of light, the electrons and holes produced by titanium dioxide photocatalyst react with water and oxygen to produce hydroxide radicals and super anion ions, thus giving the surface of the photocatalyst a strong oxidation ability, which can cut or decompose the chemical bonds that constitute organic molecules, and it does not consume electricity, no noise and no fault, which is one of the most ideal environmental purification technologies at present. Photocatalyst can effectively degrade the main polluting components in the air: formaldehyde, benzene, ammonia, volatile organic compounds, and can solidify virus proteins, destroy bacterial cell membranes, and have a bactericidal ability of 9999%。
2. Tips: The photocatalyst special effect board does not need to be replaced for life.
5. Negative oxygen ion purification method.
1. Principle: Negative oxygen ion is a negatively charged air ion, which can quickly oxidize harmful gases such as benzene and formaldehyde into negative ions, and after combining with air, reduce them to oxygen, water and carbon dioxide. This treatment method is fast-acting, pollution-free, and not easy to leave dead ends, but the life span of negative ions themselves is very short, and the existence in the air is only short-lived and fleeting.
2. Tips: Although negative oxygen ions can improve lung function and give people a relatively fresh feeling, they are helpless against pollutants.
Precautions for excessive formaldehyde in the baby's room.
1. Formaldehyde mainly comes from adhesives and related products, such as man-made boards (plywood, fiberboard, blockboard, large core board, MDF, particleboard, etc.), furniture, wallpaper (cloth), chemical fiber carpets, paints, coatings, some clothing, bags and footwear, and chemical smoke. The adhesive is mostly made of urea-formaldehyde resin, phenolic tree or melamine formaldehyde resin. To prevent formaldehyde, when using these materials, pay attention to environmental protection, which is the most critical one.
2. In the process of decoration of the baby room, even if it is an environmentally friendly product, it cannot be used excessively, such as an environmentally friendly large core board, and the dosage should not exceed 23 square meters for a living room with an area of 23 square meters.
3. Do not use the large core board with excessive formaldehyde as the liner of the composite wood floor, there have been many cases of formaldehyde pollution caused by this, the degree of pollution is proportional to the formaldehyde content in the large core board, and its release period is generally longer.
4. Do a good job in the six links of green decoration: scientific design, environmental protection building materials, standardized construction, quality supervision, green supervision and appropriate amount of flowers, the key of which is environmentally friendly building materials. To this end, when signing a contract with a decoration company, it is necessary to set a qualified authoritative unit monitoring instructions after the completion of the decoration to confirm that the harmful substances in the indoor environment meet the corresponding international standards.
5. When purchasing composite wood flooring and furniture, you must first smell and look at the safety certificate. For example, when purchasing laminate flooring, you should immediately take a piece of smell in the newly opened box, and the pungent smell is exceeded; When buying furniture, you must first read the instruction manual, and then open the door, when you smell a pungent smell, it is exceeded.
